```restructuredtext .. _bluetooth_mesh_dfd_srv: Firmware Distribution Server ############################ The Firmware Distribution Server model implements the Distributor role for the :ref:`bluetooth_mesh_dfu` subsystem. It extends the :ref:`bluetooth_mesh_blob_srv`, which it uses to receive the firmware image binary from the Initiator node. It also instantiates a :ref:`bluetooth_mesh_dfu_cli`, which it uses to distribute firmware updates throughout the mesh network. .. note:: Currently, the Firmware Distribution Server supports out-of-band (OOB) retrieval of firmware images over SMP service only. The Firmware Distribution Server does not have an API of its own, but relies on a Firmware Distribution Client model on a different device to give it information and trigger image distribution and upload. Firmware slots ************ The Firmware Distribution Server is capable of storing multiple firmware images for distribution. Each slot contains a separate firmware image with metadata, and can be distributed to other mesh nodes in the network in any order. The contents, format and size of the firmware images are vendor specific, and may contain data from other vendors. The application should never attempt to execute or modify them. The slots are managed remotely by a Firmware Distribution Client, which can both upload new slots and delete old ones. The application is notified of changes to the slots through the Firmware Distribution Server's callbacks (:cpp:type:`bt_mesh_fd_srv_cb`). While the metadata for each firmware slot is stored internally, the application must provide a :ref:`bluetooth_mesh_blob_stream` for reading and writing the firmware image.

```restructuredtext .. _bluetooth_mesh_sar_cfg: Segmentation and reassembly (SAR) ################################# Segmentation and reassembly (SAR) provides a way of handling larger upper transport layer messages in a mesh network, with a purpose of enhancing the Bluetooth Mesh throughput. The segmentation and reassembly mechanism is used by the lower transport layer. The lower transport layer defines how the upper transport layer PDUs are segmented and reassembled into multiple Lower Transport PDUs, and sends them to the lower transport layer on a peer device. If the Upper Transport PDU fits, it is sent in a single Lower Transport PDU. For longer packets, which do not fit into a single Lower Transport PDU, the lower transport layer performs segmentation, splitting the Upper Transport PDU into multiple segments. The lower transport layer on the receiving device reassembles the segments into a single Upper Transport PDU before passing it up the stack. Delivery of a segmented message is acknowledged by the lower transport layer of the receiving node, while an unsegmented message delivery is not acknowledged. However, an Upper Transport PDU that fits into one Lower Transport PDU can also be sent as a single-segment segmented message when acknowledgment by the lower transport layer is required. Set the ``send rel`` flag (see :c:struct:`bt_mesh_msg_ctx`) to use the reliable message transmission and acknowledge single-segment segmented messages. The transport layer is able to transport up to 32 segments with its SAR mechanism, with a maximum message (PDU) size of 384 octets. To configure message size for the Bluetooth Mesh stack, use the following Kconfig options: * :kconfig:option:`CONFIG_BT_MESH_RX_SEG_MAX` to set the maximum number of segments in an incoming message. * :kconfig:option:`CONFIG_BT_MESH_TX_SEG_MAX` to set the maximum number of segments in an outgoing message. The Kconfig options :kconfig:option:`CONFIG_BT_MESH_TX_SEG_MSG_COUNT` and :kconfig:option:`CONFIG_BT_MESH_RX_SEG_MSG_COUNT` define how many outgoing and incoming segmented messages can be processed simultaneously. When more than one segmented message is sent to the same destination, the messages are queued and sent one at a time. Incoming and outgoing segmented messages share the same pool for allocation of their segments. This pool size is configured through the :kconfig:option:`CONFIG_BT_MESH_SEG_BUFS` Kconfig option. Both incoming and outgoing messages allocate segments at the start of the transaction. The outgoing segmented message releases its segments one by one as soon as they are acknowledged by the receiver, while the incoming message releases the segments first after the message is fully received. Keep this in mind when defining the size of the buffers. SAR does not impose extra overhead on the access layer payload per segment. Segmentation and reassembly (SAR) Configuration models ****************************************************** With Bluetooth Mesh Protocol Specification version 1.1, it became possible to configure SAR behavior, such as intervals, timers and retransmission counters, over a mesh network using SAR Configuration models: * :ref:`bluetooth_mesh_sar_cfg_cli` * :ref:`bluetooth_mesh_sar_cfg_srv` The following SAR behavior applies regardless of the presence of a SAR Configuration Server on a node. Transmission of segments is separated by a segment transmission interval (see the `SAR Segment Interval Step`_ state). Other configurable time intervals and delays available for the segmentation and reassembly are: * Interval between unicast retransmissions (see the states `SAR Unicast Retransmissions Interval Step`_ and `SAR Unicast Retransmissions Interval Increment`_). * Interval between multicast retransmissions (see the `SAR Multicast Retransmissions Interval Step`_ state). * Segment reception interval (see the `SAR Receiver Segment Interval Step`_ state). * Acknowledgment delay increment (see the `SAR Acknowledgment Delay Increment`_ state). When the last segment marked as unacknowledged is transmitted, the lower transport layer starts a retransmissions timer. The initial value of the SAR Unicast Retransmissions timer depends on the value of the TTL field of the message. If the TTL field value is greater than ``0``, the initial value for the timer is set according to the following formula: .. math:: unicast~retransmissions~interval~step + unicast~retransmissions~interval~increment \times (TTL - 1) If the TTL field value is ``0``, the initial value of the timer is set to the unicast retransmissions interval step. The initial value of the SAR Multicast Retransmissions timer is set to the multicast retransmissions interval. When the lower transport layer receives a message segment, it starts a SAR Discard timer. The discard timer tells how long the lower transport layer waits before discarding the segmented message the segment belongs to. The initial value of the SAR Discard timer is the discard timeout value indicated by the `SAR Discard Timeout`_ state. SAR Acknowledgment timer holds the time before a Segment Acknowledgment message is sent for a received segment. The initial value of the SAR Acknowledgment timer is calculated using the following formula: .. math:: min(SegN + 0.5 , acknowledgment~delay~increment) \times segment~reception~interval The ``SegN`` field value identifies the total number of segments the Upper Transport PDU is segmented into. Four counters are related to SAR behavior: * Two unicast retransmissions counts (see `SAR Unicast Retransmissions Count`_ state and `SAR Unicast Retransmissions Without Progress Count`_ state) * Multicast retransmissions count (see `SAR Multicast Retransmissions Count`_ state) * Acknowledgment retransmissions count (see `SAR Acknowledgment Retransmissions Count`_ state) If the number of segments in the transmission is higher than the value of the `SAR Segments Threshold`_ state, Segment Acknowledgment messages are retransmitted using the value of the `SAR Acknowledgment Retransmissions Count`_ state. .. _bt_mesh_sar_cfg_states: SAR states ********** There are two states defined related to segmentation and reassembly: * SAR Transmitter state * SAR Receiver state The SAR Transmitter state is a composite state that controls the number and timing of transmissions of segmented messages. It includes the following states: * SAR Segment Interval Step * SAR Unicast Retransmissions Count * SAR Unicast Retransmissions Without Progress Count * SAR Unicast Retransmissions Interval Step * SAR Unicast Retransmissions Interval Increment * SAR Multicast Retransmissions Count * SAR Multicast Retransmissions Interval Step The SAR Receiver state is a composite state that controls the number and timing of Segment Acknowledgment transmissions and the discarding of reassembly of a segmented message. It includes the following states: * SAR Segments Threshold * SAR Discard Timeout * SAR Acknowledgment Delay Increment * SAR Acknowledgment Retransmissions Count * SAR Receiver Segment Interval Step SAR Segment Interval Step ========================= SAR Segment Interval Step state holds a value that controls the interval between transmissions of segments of a segmented message. The interval is measured in milliseconds. Use the :kconfig:option:`CONFIG_BT_MESH_SAR_TX_SEG_INT_STEP` Kconfig option to set the default value. Segment transmission interval is then calculated using the following formula: .. math:: (\mathtt{CONFIG\_BT\_MESH\_SAR\_TX\_SEG\_INT\_STEP} + 1) \times 10~\text{ms} SAR Unicast Retransmissions Count ================================= SAR Unicast Retransmissions Count holds a value that defines the maximum number of retransmissions of a segmented message to a unicast destination. Use the :kconfig:option:`CONFIG_BT_MESH_SAR_TX_UNICAST_RETRANS_COUNT` Kconfig option to set the default value for this state. SAR Unicast Retransmissions Without Progress Count ================================================== This state holds a value that defines the maximum number of retransmissions of a segmented message to a unicast address that will be sent if no acknowledgment was received during the timeout, or if an acknowledgment with already confirmed segments was received. Use the Kconfig option :kconfig:option:`CONFIG_BT_MESH_SAR_TX_UNICAST_RETRANS_WITHOUT_PROG_COUNT` to set the maximum number of retransmissions. SAR Unicast Retransmissions Interval Step ========================================= The value of this state controls the interval step used for delaying the retransmissions of unacknowledged segments of a segmented message to a unicast address. The interval step is measured in milliseconds. Use the :kconfig:option:`CONFIG_BT_MESH_SAR_TX_UNICAST_RETRANS_INT_STEP` Kconfig option to set the default value. This value is then used to calculate the interval step using the following formula: .. math:: (\mathtt{CONFIG\_BT\_MESH\_SAR\_TX\_UNICAST\_RETRANS\_INT\_STEP} + 1) \times 25~\text{ms} SAR Unicast Retransmissions Interval Increment ============================================== SAR Unicast Retransmissions Interval Increment holds a value that controls the interval increment used for delaying the retransmissions of unacknowledged segments of a segmented message to a unicast address. The increment is measured in milliseconds. Use the Kconfig option :kconfig:option:`CONFIG_BT_MESH_SAR_TX_UNICAST_RETRANS_INT_INC` to set the default value. The Kconfig option value is used to calculate the increment using the following formula: .. math:: (\mathtt{CONFIG\_BT\_MESH\_SAR\_TX\_UNICAST\_RETRANS\_INT\_INC} + 1) \times 25~\text{ms} SAR Multicast Retransmissions Count =================================== The state holds a value that controls the total number of retransmissions of a segmented message to a multicast address. Use the Kconfig option :kconfig:option:`CONFIG_BT_MESH_SAR_TX_MULTICAST_RETRANS_COUNT` to set the total number of retransmissions. SAR Multicast Retransmissions Interval Step =========================================== This state holds a value that controls the interval between retransmissions of all segments in a segmented message to a multicast address. The interval is measured in milliseconds. Use the Kconfig option :kconfig:option:`CONFIG_BT_MESH_SAR_TX_MULTICAST_RETRANS_INT` to set the default value that is used to calculate the interval using the following formula: .. math:: (\mathtt{CONFIG\_BT\_MESH\_SAR\_TX\_MULTICAST\_RETRANS\_INT} + 1) \times 25~\text{ms} SAR Discard Timeout =================== The value of this state defines the time in seconds that the lower transport layer waits after receiving segments of a segmented message before discarding that segmented message. Use the Kconfig option :kconfig:option:`CONFIG_BT_MESH_SAR_RX_DISCARD_TIMEOUT` to set the default value. The discard timeout will be calculated using the following formula: .. math:: (\mathtt{CONFIG\_BT\_MESH\_SAR\_RX\_DISCARD\_TIMEOUT} + 1) \times 5~\text{seconds} SAR Acknowledgment Delay Increment ================================== This state holds a value that controls the delay increment of an interval used for delaying the transmission of an acknowledgment message after receiving a new segment. The increment is measured in segments. Use the Kconfig option :kconfig:option:`CONFIG_BT_MESH_SAR_RX_ACK_DELAY_INC` to set the default value. The increment value is calculated to be :math:`\verb\|CONFIG_BT_MESH_SAR_RX_ACK_DELAY_INC\| + 1.5`. SAR Segments Threshold ====================== SAR Segments Threshold state holds a value that defines a threshold in number of segments of a segmented message for acknowledgment retransmissions. Use the Kconfig option :kconfig:option:`CONFIG_BT_MESH_SAR_RX_SEG_THRESHOLD` to set the threshold. When the number of segments of a segmented message is above this threshold, the stack will additionally retransmit every acknowledgment message the number of times given by the value of :kconfig:option:`CONFIG_BT_MESH_SAR_RX_ACK_RETRANS_COUNT`. SAR Acknowledgment Retransmissions Count ======================================== The SAR Acknowledgment Retransmissions Count state controls the number of retransmissions of Segment Acknowledgment messages sent by the lower transport layer. It gives the total number of retranmissions of an acknowledgment message that the stack will additionally send when the size of segments in a segmented message is above the :kconfig:option:`CONFIG_BT_MESH_SAR_RX_SEG_THRESHOLD` value. Use the Kconfig option :kconfig:option:`CONFIG_BT_MESH_SAR_RX_ACK_RETRANS_COUNT` to set the default value for this state. The maximum number of transmissions of a Segment Acknowledgment message is :math:`\verb\|CONFIG_BT_MESH_SAR_RX_ACK_RETRANS_COUNT\| + 1`. SAR Receiver Segment Interval Step ================================== The SAR Receiver Segment Interval Step defines the segments reception interval step used for delaying the transmission of an acknowledgment message after receiving a new segment. The interval is measured in milliseconds. Use the Kconfig option :kconfig:option:`CONFIG_BT_MESH_SAR_RX_SEG_INT_STEP` to set the default value and calculate the interval using the following formula: .. math:: (\mathtt{CONFIG\_BT\_MESH\_SAR\_RX\_SEG\_INT\_STEP} + 1) \times 10~\text{ms} ```	/content/code_sandbox/doc/connectivity/bluetooth/api/mesh/sar_cfg.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	2,938
```restructuredtext .. _bluetooth_mesh_shell: Bluetooth Mesh Shell #################### The Bluetooth Mesh shell subsystem provides a set of Bluetooth Mesh shell commands for the :ref:`shell_api` module. It allows for testing and exploring the Bluetooth Mesh API through an interactive interface, without having to write an application. The Bluetooth Mesh shell interface provides access to most Bluetooth Mesh features, including provisioning, configuration, and message sending. Prerequisites *********** The Bluetooth Mesh shell subsystem depends on the application to create the composition data and do the mesh initialization. Application ******* The Bluetooth Mesh shell subsystem is most easily used through the Bluetooth Mesh shell application under ``tests/bluetooth/mesh_shell``. See :ref:`shell_api` for information on how to connect and interact with the Bluetooth Mesh shell application. Basic usage ********* The Bluetooth Mesh shell subsystem adds a single ``mesh`` command, which holds a set of sub-commands. Every time the device boots up, make sure to call ``mesh init`` before any of the other Bluetooth Mesh shell commands can be called:: uart:~$ mesh init This is done to ensure that all available log will be printed to the shell output. Provisioning ============ The mesh node must be provisioned to become part of the network. This is only necessary the first time the device boots up, as the device will remember its provisioning data between reboots. The simplest way to provision the device is through self-provisioning. To do this the user must provision the device with the default network key and address ``0x0001``, execute:: uart:~$ mesh prov local 0 0x0001 Since all mesh nodes use the same values for the default network key, this can be done on multiple devices, as long as they're assigned non-overlapping unicast addresses. Alternatively, to provision the device into an existing network, the unprovisioned beacon can be enabled with ``mesh prov pb-adv on`` or ``mesh prov pb-gatt on``. The beacons can be picked up by an external provisioner, which can provision the node into its network. Once the mesh node is part of a network, its transmission parameters can be controlled by the general configuration commands: * To set the destination address, call ``mesh target dst <Addr>``. * To set the network key index, call ``mesh target net <NetKeyIdx>``. * To set the application key index, call ``mesh target app <AppKeyIdx>``. By default, the transmission parameters are set to send messages to the provisioned address and network key. Configuration ============= By setting the destination address to the local unicast address (``0x0001`` in the ``mesh prov local`` command above), we can perform self-configuration through any of the :ref:`bluetooth_mesh_shell_cfg_cli` commands. A good first step is to read out the node's own composition data:: uart:~$ mesh models cfg get-comp This prints a list of the composition data of the node, including a list of its model IDs. Next, since the device has no application keys by default, it's a good idea to add one:: uart:~$ mesh models cfg appkey add 0 0 Message sending =============== With an application key added (see above), the mesh node's transition parameters are all valid, and the Bluetooth Mesh shell can send raw mesh messages through the network. For example, to send a Generic OnOff Set message, call:: uart:~$ mesh test net-send 82020100 .. note:: All multibyte fields model messages are in little endian, except the opcode. The message will be sent to the current destination address, using the current network and application key indexes. As the destination address points to the local unicast address by default, the device will only send packets to itself. To change the destination address to the All Nodes broadcast address, call:: uart:~$ mesh target dst 0xffff With the destination address set to ``0xffff``, any other mesh nodes in the network with the configured network and application keys will receive and process the messages we send. .. note:: To change the configuration of the device, the destination address must be set back to the local unicast address before issuing any configuration commands. Sending raw mesh packets is a good way to test model message handler implementations during development, as it can be done without having to implement the sending model. By default, only the reception of the model messages can be tested this way, as the Bluetooth Mesh shell only includes the foundation models. To receive a packet in the mesh node, you have to add a model with a valid opcode handler list to the composition data in ``subsys/bluetooth/mesh/shell.c``, and print the incoming message to the shell in the handler callback. Parameter formats ***************** The Bluetooth Mesh shell commands are parsed with a variety of formats: .. list-table:: Parameter formats :widths: 1 4 2 :header-rows: 1 * - Type - Description - Example * - Integers - The default format unless something else is specified. Can be either decimal or hexadecimal. - ``1234``, ``0xabcd01234`` * - Hexstrings - For raw byte arrays, like UUIDs, key values and message payloads, the parameters should be formatted as an unbroken string of hexadecimal values without any prefix. - ``deadbeef01234`` * - Booleans - Boolean values are denoted in the API documentation as ``<val(off, on)>``. - ``on``, ``off``, ``enabled``, ``disabled``, ``1``, ``0`` Commands ******** The Bluetooth Mesh shell implements a large set of commands. Some of the commands accept parameters, which are mentioned in brackets after the command name. For example, ``mesh lpn set <value: off, on>``. Mandatory parameters are marked with angle brackets (e.g. ``<NetKeyIdx>``), and optional parameters are marked with square brackets (e.g. ``[DstAddr]``). The Bluetooth Mesh shell commands are divided into the following groups: .. contents:: :depth: 1 :local: .. note:: Some commands depend on specific features being enabled in the compile time configuration of the application. Not all features are enabled by default. The list of available Bluetooth mesh shell commands can be shown in the shell by calling ``mesh`` without any arguments. General configuration ===================== ``mesh init`` ------------- Initialize the mesh shell. This command must be run before any other mesh command. ``mesh reset-local`` -------------------- Reset the local mesh node to its initial unprovisioned state. This command will also clear the Configuration Database (CDB) if present. Target ====== The target commands enables the user to monitor and set the target destination address, network index and application index for the shell. These parameters are used by several commands, like provisioning, Configuration Client, etc. ``mesh target dst [DstAddr]`` ----------------------------- Get or set the message destination address. The destination address determines where mesh packets are sent with the shell, but has no effect on modules outside the shell's control. * ``DstAddr``: If present, sets the new 16-bit mesh destination address. If omitted, the current destination address is printed. ``mesh target net [NetKeyIdx]`` ------------------------------- Get or set the message network index. The network index determines which network key is used to encrypt mesh packets that are sent with the shell, but has no effect on modules outside the shell's control. The network key must already be added to the device, either through provisioning or by a Configuration Client. * ``NetKeyIdx``: If present, sets the new network index. If omitted, the current network index is printed. ``mesh target app [AppKeyIdx]`` ------------------------------- Get or set the message application index. The application index determines which application key is used to encrypt mesh packets that are sent with the shell, but has no effect on modules outside the shell's control. The application key must already be added to the device by a Configuration Client, and must be bound to the current network index. * ``AppKeyIdx``: If present, sets the new application index. If omitted, the current application index is printed. Low Power Node ============== ``mesh lpn set <Val(off, on)>`` ------------------------------- Enable or disable Low Power operation. Once enabled, the device will turn off its radio and start polling for friend nodes. * ``Val``: Sets whether Low Power operation is enabled. ``mesh lpn poll`` ----------------- Perform a poll to the friend node, to receive any pending messages. Only available when LPN is enabled. Testing ======= ``mesh test net-send <HexString>`` ----------------------------------- Send a raw mesh message with the current destination address, network and application index. The message opcode must be encoded manually. * ``HexString`` Raw hexadecimal representation of the message to send. ``mesh test iv-update`` ----------------------- Force an IV update. ``mesh test iv-update-test <Val(off, on)>`` ------------------------------------------- Set the IV update test mode. In test mode, the IV update timing requirements are bypassed. * ``Val``: Enable or disable the IV update test mode. ``mesh test rpl-clear`` ----------------------- Clear the replay protection list, forcing the node to forget all received messages. .. warning:: Clearing the replay protection list breaks the security mechanisms of the mesh node, making it susceptible to message replay attacks. This should never be performed in a real deployment. Health Server Test ------------------ ``mesh test health-srv add-fault <FaultID>`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Register a new Health Server Fault for the Linux Foundation Company ID. * ``FaultID``: ID of the fault to register (``0x0001`` to ``0xFFFF``) ``mesh test health-srv del-fault [FaultID]`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Remove registered Health Server faults for the Linux Foundation Company ID. * ``FaultID``: If present, the given fault ID will be deleted. If omitted, all registered faults will be cleared. Provisioning ============ To allow a device to broadcast connectable unprovisioned beacons, the :kconfig:option:`CONFIG_BT_MESH_PROVISIONEE` configuration option must be enabled, along with the :kconfig:option:`CONFIG_BT_MESH_PB_GATT` option. ``mesh prov pb-gatt <Val(off, on)>`` ------------------------------------ Start or stop advertising a connectable unprovisioned beacon.

Defaults to 0 if omitted. ``mesh prov beacon-listen <Val(off, on)>`` ------------------------------------------ Enable or disable printing of incoming unprovisioned beacons. Allows a provisioner device to detect nearby unprovisioned devices and provision them. To enable this command, the :kconfig:option:`CONFIG_BT_MESH_SHELL_PROV_CTX_INSTANCE` option must be enabled. * ``Val``: Whether to enable the unprovisioned beacon printing. ``mesh prov remote-pub-key <PubKey>`` ------------------------------------- Provide Device public key. * ``PubKey`` - Device public key in big-endian. ``mesh prov auth-method input <Action> <Size>`` ----------------------------------------------- From the provisioner device, instruct the unprovisioned device to use the specified Input OOB authentication action. * ``Action`` - Input action.

This is implemented as a separate module (``mesh models cfg``) inside the ``mesh models`` subcommand list. This module will work on any instance of the Configuration Client model if the mentioned shell configuration options is enabled, and as long as the Configuration Client model is present in the model composition of the application. This shell module can be used for configuring itself and other nodes in the mesh network. The Configuration Client uses general message parameters set by ``mesh target dst`` and ``mesh target net`` to target specific nodes. When the Bluetooth Mesh shell node is provisioned, given that the :kconfig:option:`CONFIG_BT_MESH_SHELL_PROV_CTX_INSTANCE` option is enabled with the shell provisioning context initialized, the Configuration Client model targets itself by default. Similarly, when another node has been provisioned by the Bluetooth Mesh shell, the Configuration Client model targets the new node. In most common use-cases, the Configuration Client is depending on the provisioning features and the Configuration database to be fully functional. The Configuration Client always sends messages using the Device key bound to the destination address, so it will only be able to configure itself and the mesh nodes it provisioned. The following steps are an example of how you can set up a device to start using the Configuration Client commands: * Initialize the client node (``mesh init``). * Create the CDB (``mesh cdb create``). * Provision the local device (``mesh prov local``). * The shell module should now target itself. * Monitor the composition data of the local node (``mesh models cfg get-comp``). * Configure the local node as desired with the Configuration Client commands. * Provision other devices (``mesh prov beacon-listen``) (``mesh prov remote-adv``) (``mesh prov remote-gatt``). * The shell module should now target the newly added node. * Monitor the newly provisioned nodes and their addresses (``mesh cdb show``). * Monitor the composition data of the target device (``mesh models cfg get-comp``). * Configure the node as desired with the Configuration Client commands. ``mesh models cfg target get`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Get the target Configuration server for the Configuration Client model. ``mesh models cfg help`` ^^^^^^^^^^^^^^^^^^^^^^^^ Print information for the Configuration Client shell module. ``mesh models cfg reset`` ^^^^^^^^^^^^^^^^^^^^^^^^^ Reset the target device. ``mesh models cfg timeout [Timeout(s)]`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Get and set the Config Client model timeout used during message sending. * ``Timeout``: If present, set the Config Client model timeout in seconds.

Health Client ------------- The Health Client model is an optional mesh subsystem that can be enabled through the :kconfig:option:`CONFIG_BT_MESH_HEALTH_CLI` configuration option. This is implemented as a separate module (``mesh models health``) inside the ``mesh models`` subcommand list. This module will work on any instance of the Health Client model if the mentioned shell configuration options is enabled, and as long as one or more Health Client model(s) is present in the model composition of the application. This shell module can be used to trigger interaction between Health Clients and Servers on devices in a Mesh network. By default, the module will choose the first Health Client instance in the model composition when using the Health Client commands. To choose a specific Health Client instance the user can utilize the commands ``mesh models health instance set`` and ``mesh models health instance get-all``. The Health Client may use the general messages parameters set by ``mesh target dst``, ``mesh target net`` and ``mesh target app`` to target specific nodes.

Can only be called after a DFU transfer is completed, and the Distributor has requested that the transfer is applied. As the mesh shell Firmware Update Server doesn't actually apply the incoming firmware image, this command can be used to emulate an applied status, to notify the Distributor that the transfer was successful. ``mesh models dfu srv progress`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Check the progress of the current transfer. ``mesh models dfu srv rx-cancel`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Cancel incoming DFU transfer. ``mesh models dfu srv instance-set <ElemIdx>`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Use the Firmware Update Server model instance on the specified element when using the other Firmware Update Server model commands. * ``ElemIdx``: The element on which to find the Firmware Update Server model instance to use. ``mesh models dfu srv instance-get-all`` ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Get a list of all Firmware Update Server model instances on the node. .. _bluetooth_mesh_shell_dfd_server: Firmware Distribution Server model ---------------------------------- The Firmware Distribution Server model commands can be added to the mesh shell by enabling the :kconfig:option:`CONFIG_BT_MESH_DFD_SRV` configuration option.

```restructuredtext .. _bluetooth_mesh_core: Core #### The core provides functionality for managing the general Bluetooth Mesh state. .. _bluetooth_mesh_lpn: Low Power Node ************ The Low Power Node (LPN) role allows battery powered devices to participate in a mesh network as a leaf node. An LPN interacts with the mesh network through a Friend node, which is responsible for relaying any messages directed to the LPN. The LPN saves power by keeping its radio turned off, and only wakes up to either send messages or poll the Friend node for any incoming messages. The radio control and polling is managed automatically by the mesh stack, but the LPN API allows the application to trigger the polling at any time through :c:func:`bt_mesh_lpn_poll`. The LPN operation parameters, including poll interval, poll event timing and Friend requirements is controlled through the :kconfig:option:`CONFIG_BT_MESH_LOW_POWER` option and related configuration options. When using the LPN feature with logging, it is strongly recommended to only use the :kconfig:option:`CONFIG_LOG_MODE_DEFERRED` option. Log modes other than the deferred may cause unintended delays during processing of log messages. This in turns will affect scheduling of the receive delay and receive window. The same limitation applies for the :kconfig:option:`CONFIG_BT_MESH_FRIEND` option. Replay Protection List ****************** The Replay Protection List (RPL) is used to hold recently received sequence numbers from elements within the mesh network to perform protection against replay attacks. To keep a node protected against replay attacks after reboot, it needs to store the entire RPL in the persistent storage before it is powered off. Depending on the amount of traffic in a mesh network, storing recently seen sequence numbers can make flash wear out sooner or later. To mitigate this, :kconfig:option:`CONFIG_BT_MESH_RPL_STORE_TIMEOUT` can be used. This option postpones storing of RPL entries in the persistent storage. This option, however, doesn't completely solve the issue as the node may get powered off before the timer to store the RPL is fired. To ensure that messages can not be replayed, the node can initiate storage of the pending RPL entry (or entries) at any time (or sufficiently before power loss) by calling :c:func:`bt_mesh_rpl_pending_store`. This is up to the node to decide, which RPL entries are to be stored in this case. Setting :kconfig:option:`CONFIG_BT_MESH_RPL_STORE_TIMEOUT` to -1 allows to completely switch off the timer, which can help to significantly reduce flash wear out. This moves the responsibility of storing RPL to the user application and requires that sufficient power backup is available from the time this API is called until all RPL entries are written to the flash. Finding the right balance between :kconfig:option:`CONFIG_BT_MESH_RPL_STORE_TIMEOUT` and calling :c:func:`bt_mesh_rpl_pending_store` may reduce a risk of security vulnerability and flash wear out. .. warning: Failing to enable :kconfig:option:`CONFIG_BT_SETTINGS`, or setting :kconfig:option:`CONFIG_BT_MESH_RPL_STORE_TIMEOUT` to -1 and not storing the RPL between reboots, will make the device vulnerable to replay attacks and not perform the replay protection required by the spec. .. _bluetooth_mesh_persistent_storage: Persistent storage ************** The mesh stack uses the :ref:`Settings Subsystem <settings_api>` for storing the device configuration persistently. When the stack configuration changes and the change needs to be stored persistently, the stack schedules a work item. The delay between scheduling the work item and submitting it to the workqueue is defined by the :kconfig:option:`CONFIG_BT_MESH_STORE_TIMEOUT` option. Once storing of data is scheduled, it can not be rescheduled until the work item is processed. Exceptions are made in certain cases as described below. When IV index, Sequence Number or CDB configuration have to be stored, the work item is submitted to the workqueue without the delay. If the work item was previously scheduled, it will be rescheduled without the delay. The Replay Protection List uses the same work item to store RPL entries. If storing of RPL entries is requested and no other configuration is pending to be stored, the delay is set to :kconfig:option:`CONFIG_BT_MESH_RPL_STORE_TIMEOUT`. If other stack configuration has to be stored, the delay defined by the :kconfig:option:`CONFIG_BT_MESH_STORE_TIMEOUT` option is less than :kconfig:option:`CONFIG_BT_MESH_RPL_STORE_TIMEOUT`, and the work item was scheduled by the Replay Protection List, the work item will be rescheduled. When the work item is running, the stack will store all pending configuration, including the RPL entries. Work item execution context =========================== The :kconfig:option:`CONFIG_BT_MESH_SETTINGS_WORKQ` option configures the context from which the work item is executed. This option is enabled by default, and results in stack using a dedicated cooperative thread to process the work item. This allows the stack to process other incoming and outgoing messages, as well as other work items submitted to the system workqueue, while the stack configuration is being stored. When this option is disabled, the work item is submitted to the system workqueue. This means that the system workqueue is blocked for the time it takes to store the stack's configuration. It is not recommended to disable this option as this will make the device non-responsive for a noticeable amount of time. .. _bluetooth_mesh_adv_identity: Advertisement identity ****************** All mesh stack bearers advertise data with the :c:macro:`BT_ID_DEFAULT` local identity. The value is preset in the mesh stack implementation. When Bluetooth Low Energy (LE) and Bluetooth Mesh coexist on the same device, the application should allocate and configure another local identity for Bluetooth LE purposes before starting the communication.

```restructuredtext .. _bluetooth_mesh_models_priv_beacon_srv: Private Beacon Server ##################### The Private Beacon Server model is a foundation model defined by the Bluetooth mesh specification. It is enabled with :kconfig:option:`CONFIG_BT_MESH_PRIV_BEACON_SRV` option. The Private Beacon Server model is introduced in the Bluetooth Mesh Protocol Specification version 1.1, and controls the mesh node's Private Beacon state, Private GATT Proxy state and Private Node Identity state. The Private Beacons feature adds privacy to the different Bluetooth Mesh beacons by periodically randomizing the beacon input data. This protects the mesh node from being tracked by devices outside the mesh network, and hides the network's IV index, IV update and the Key Refresh state. The Private Beacon Server must be instantiated for the device to support sending of the private beacons, but the node will process received private beacons without it. The Private Beacon Server does not have an API of its own, but relies on a :ref:`bluetooth_mesh_models_priv_beacon_cli` to control it. The Private Beacon Server model only accepts messages encrypted with the node's device key. The application can configure the initial parameters of the Private Beacon Server model through the :c:struct:`bt_mesh_priv_beacon_srv` instance passed to :c:macro:`BT_MESH_MODEL_PRIV_BEACON_SRV`. Note that if the mesh node stored changes to this configuration in the settings subsystem, the initial values may be overwritten upon loading. If present, the Private Beacon Server model must only be instantiated on the primary element.

```restructuredtext .. _bluetooth_mesh_cfg: Runtime Configuration ##################### The runtime configuration API allows applications to change their runtime configuration directly, without going through the Configuration models. Bluetooth Mesh nodes should generally be configured by a central network configurator device with a :ref:`bluetooth_mesh_models_cfg_cli` model. Each mesh node instantiates a :ref:`bluetooth_mesh_models_cfg_srv` model that the Configuration Client can communicate with to change the node configuration. In some cases, the mesh node can't rely on the Configuration Client to detect or determine local constraints, such as low battery power or changes in topology.

```restructuredtext .. _bluetooth_mesh_blob_srv: BLOB Transfer Server #################### The Binary Large Object (BLOB) Transfer Server model implements reliable receiving of large binary objects. It serves as the backend of the :ref:`bluetooth_mesh_dfu_srv`, but can also be used for receiving other binary images. BLOBs *** As described in :ref:`bluetooth_mesh_blob`, the binary objects transferred by the BLOB Transfer models are divided into blocks, which are divided into chunks. As the transfer is controlled by the BLOB Transfer Client model, the BLOB Transfer Server must allow blocks to come in any order. The chunks within a block may also come in any order, but all chunks in a block must be received before the next block is started. The BLOB Transfer Server keeps track of the received blocks and chunks, and will process each block and chunk only once. The BLOB Transfer Server also ensures that any missing chunks are resent by the BLOB Transfer Client. Usage *** The BLOB Transfer Server is instantiated on an element with a set of event handler callbacks: .. code-block:: C static const struct bt_mesh_blob_srv_cb blob_cb = { /* Callbacks / }; static struct bt_mesh_blob_srv blob_srv = { .cb = &blob_cb, }; static const struct bt_mesh_model models[] = { BT_MESH_MODEL_BLOB_SRV(&blob_srv), }; A BLOB Transfer Server is capable of receiving a single BLOB transfer at a time. Before the BLOB Transfer Server can receive a transfer, it must be prepared by the user. The transfer ID must be passed to the BLOB Transfer Server through the :c:func:`bt_mesh_blob_srv_recv` function before the transfer is started by the BLOB Transfer Client. The ID must be shared between the BLOB Transfer Client and the BLOB Transfer Server through some higher level procedure, like a vendor specific transfer management model. Once the transfer has been set up on the BLOB Transfer Server, it's ready for receiving the BLOB. The application is notified of the transfer progress through the event handler callbacks, and the BLOB data is sent to the BLOB stream. The interaction between the BLOB Transfer Server, BLOB stream and application is shown below: .. figure:: images/blob_srv.svg :align: center :alt: BLOB Transfer Server model interaction BLOB Transfer Server model interaction Transfer suspension **************** The BLOB Transfer Server keeps a running timer during the transfer, that is reset on every received message. If the BLOB Transfer Client does not send a message before the transfer timer expires, the transfer is suspended by the BLOB Transfer Server. The BLOB Transfer Server notifies the user of the suspension by calling the :c:member:`suspended <bt_mesh_blob_srv_cb.suspended>` callback. If the BLOB Transfer Server is in the middle of receiving a block, this block is discarded. The BLOB Transfer Client may resume a suspended transfer by starting a new block transfer. The BLOB Transfer Server notifies the user by calling the :c:member:`resume <bt_mesh_blob_srv_cb.resume>` callback. Transfer recovery ************* The state of the BLOB transfer is stored persistently. If a reboot occurs, the BLOB Transfer Server will attempt to recover the transfer. When the Bluetooth Mesh subsystem is started (for instance by calling :c:func:`bt_mesh_init`), the BLOB Transfer Server will check for aborted transfers, and call the :c:member:`recover <bt_mesh_blob_srv_cb.recover>` callback if there is any. In the recover callback, the user must provide a BLOB stream to use for the rest of the transfer. If the recover callback doesn't return successfully or does not provide a BLOB stream, the transfer is abandoned. If no recover callback is implemented, transfers are always abandoned after a reboot. After a transfer is successfully recovered, the BLOB Transfer Server enters the suspended state. It will stay suspended until the BLOB Transfer Client resumes the transfer, or the user cancels it. .. note:: The BLOB Transfer Client sending the transfer must support transfer recovery for the transfer to complete. If the BLOB Transfer Client has already given up the transfer, the BLOB Transfer Server will stay suspended until the application calls :c:func:`bt_mesh_blob_srv_cancel`.

```restructuredtext .. _bluetooth_mesh_provisioning: Provisioning ############ Provisioning is the process of adding devices to a mesh network. It requires two devices operating in the following roles: * The provisioner represents the network owner, and is responsible for adding new nodes to the mesh network. * The provisionee is the device that gets added to the network through the Provisioning process. Before the provisioning process starts, the provisionee is an unprovisioned device. The Provisioning module in the Zephyr Bluetooth Mesh stack supports both the Advertising and GATT Provisioning bearers for the provisionee role, as well as the Advertising Provisioning bearer for the provisioner role. The Provisioning process ************************ All Bluetooth Mesh nodes must be provisioned before they can participate in a Bluetooth Mesh network. The Provisioning API provides all the functionality necessary for a device to become a provisioned mesh node. Provisioning is a five-step process, involving the following steps: * Beaconing * Invitation * Public key exchange * Authentication * Provisioning data transfer Beaconing ========= To start the provisioning process, the unprovisioned device must first start broadcasting the Unprovisioned Beacon. This makes it visible to nearby provisioners, which can initiate the provisioning. To indicate that the device needs to be provisioned, call :c:func:`bt_mesh_prov_enable`. The device starts broadcasting the Unprovisioned Beacon with the device UUID and the ``OOB information`` field, as specified in the ``prov`` parameter passed to :c:func:`bt_mesh_init`. Additionally, a Uniform Resource Identifier (URI) may be specified, which can point the provisioner to the location of some Out Of Band information, such as the device's public key or an authentication value database. The URI is advertised in a separate beacon, with a URI hash included in the unprovisioned beacon, to tie the two together. Uniform Resource Identifier --------------------------- The Uniform Resource Identifier shall follow the format specified in the Bluetooth Core Specification Supplement. The URI must start with a URI scheme, encoded as a single utf-8 data point, or the special ``none`` scheme, encoded as ``0x01``. The available schemes are listed on the `Bluetooth website <path_to_url`_. Examples of encoded URIs: .. list-table:: URI encoding examples * - URI - Encoded * - ``path_to_url`` - ``\x16//example.com`` * - ``path_to_url`` - ``\x17//www.zephyrproject.org/`` * - ``just a string`` - ``\x01just a string`` Provisioning invitation ======================= The provisioner initiates the Provisioning process by sending a Provisioning invitation. The invitations prompts the provisionee to call attention to itself using the Health Server :ref:`bluetooth_mesh_models_health_srv_attention`, if available. The Unprovisioned device automatically responds to the invite by presenting a list of its capabilities, including the supported Out of Band Authentication methods and algorithms. Public key exchange =================== Before the provisioning process can begin, the provisioner and the unprovisioned device exchange public keys, either in-band or Out of Band (OOB). In-band public key exchange is a part of the provisioning process and always supported by the unprovisioned device and provisioner. If the application wants to support public key exchange via OOB, it needs to provide public and private keys to the mesh stack. The unprovisioned device will reflect this in its capabilities. The provisioner obtains the public key via any available OOB mechanism (e.g. the device may advertise a packet containing the public key or it can be encoded in a QR code printed on the device packaging). Note that even if the unprovisioned device has specified the public key for the Out of Band exchange, the provisioner may choose to exchange the public key in-band if it can't retrieve the public key via OOB mechanism. In this case, a new key pair will be generated by the mesh stack for each Provisioning process. To enable support of OOB public key on the unprovisioned device side, :kconfig:option:`CONFIG_BT_MESH_PROV_OOB_PUBLIC_KEY` needs to be enabled. The application must provide public and private keys before the Provisioning process is started by initializing pointers to :c:member:`bt_mesh_prov.public_key_be` and :c:member:`bt_mesh_prov.private_key_be`. The keys needs to be provided in big-endian bytes order. To provide the device's public key obtained via OOB, call :c:func:`bt_mesh_prov_remote_pub_key_set` on the provisioner side. Authentication ============== After the initial exchange, the provisioner selects an Out of Band (OOB) Authentication method. This allows the user to confirm that the device the provisioner connected to is actually the device they intended, and not a malicious third party. The Provisioning API supports the following authentication methods for the provisionee: * Static OOB: An authentication value is assigned to the device in production, which the provisioner can query in some application specific way. * Input OOB: The user inputs the authentication value. The available input actions are listed in :c:enum:`bt_mesh_input_action_t`. * Output OOB: Show the user the authentication value. The available output actions are listed in :c:enum:`bt_mesh_output_action_t`. The application must provide callbacks for the supported authentication methods in :c:struct:`bt_mesh_prov`, as well as enabling the supported actions in :c:member:`bt_mesh_prov.output_actions` and :c:member:`bt_mesh_prov.input_actions`. When an Output OOB action is selected, the authentication value should be presented to the user when the output callback is called, and remain until the :c:member:`bt_mesh_prov.input_complete` or :c:member:`bt_mesh_prov.complete` callback is called. If the action is ``blink``, ``beep`` or ``vibrate``, the sequence should be repeated after a delay of three seconds or more. When an Input OOB action is selected, the user should be prompted when the application receives the :c:member:`bt_mesh_prov.input` callback. The user response should be fed back to the Provisioning API through :c:func:`bt_mesh_input_string` or :c:func:`bt_mesh_input_number`. If no user response is recorded within 60 seconds, the Provisioning process is aborted. If Provisionee wants to mandate OOB authentication, it is mandatory to use the BT_MESH_ECDH_P256_HMAC_SHA256_AES_CCM algorithm. Data transfer ============= After the device has been successfully authenticated, the provisioner transfers the Provisioning data: * Unicast address * A network key * IV index * Network flags * Key refresh * IV update Additionally, a device key is generated for the node. All this data is stored by the mesh stack, and the provisioning :c:member:`bt_mesh_prov.complete` callback gets called. Provisioning security ******************* Depending on the choice of public key exchange mechanism and authentication method, the provisioning process can be secure or insecure. On May 24th 2021, ANSSI `disclosed <path_to_url`_ a set of vulnerabilities in the Bluetooth Mesh provisioning protocol that showcased how the low entropy provided by the Blink, Vibrate, Push, Twist and Input/Output numeric OOB methods could be exploited in impersonation and MITM attacks. In response, the Bluetooth SIG has reclassified these OOB methods as insecure in the Bluetooth Mesh Profile Specification v1.0.1 `erratum 16350 <path_to_url`_, as AuthValue may be brute forced in real time. To ensure secure provisioning, applications should use a static OOB value and OOB public key transfer.

```restructuredtext .. _bluetooth_mesh_models_rpr_cli: Remote Provisioning Client ########################## The Remote Provisioning Client model is a foundation model defined by the Bluetooth mesh specification. It is enabled with the :kconfig:option:`CONFIG_BT_MESH_RPR_CLI` option. The Remote Provisioning Client model is introduced in the Bluetooth Mesh Protocol Specification version 1.1. This model provides functionality to remotely provision devices into a mesh network, and perform Node Provisioning Protocol Interface procedures by interacting with mesh nodes that support the :ref:`bluetooth_mesh_models_rpr_srv` model. The Remote Provisioning Client model communicates with a Remote Provisioning Server model using the device key of the node containing the target Remote Provisioning Server model instance. If present, the Remote Provisioning Client model must be instantiated on the primary element. Scanning ******** The scanning procedure is used to scan for unprovisioned devices located nearby the Remote Provisioning Server. The Remote Provisioning Client starts a scan procedure by using the :c:func:`bt_mesh_rpr_scan_start` call: .. code-block:: C static void rpr_scan_report(struct bt_mesh_rpr_cli cli, const struct bt_mesh_rpr_node srv, struct bt_mesh_rpr_unprov unprov, struct net_buf_simple adv_data) { } struct bt_mesh_rpr_cli rpr_cli = { .scan_report = rpr_scan_report, }; const struct bt_mesh_rpr_node srv = { .addr = 0x0004, .net_idx = 0, .ttl = BT_MESH_TTL_DEFAULT, }; struct bt_mesh_rpr_scan_status status; uint8_t uuid = NULL; uint8_t timeout = 10; uint8_t max_devs = 3; bt_mesh_rpr_scan_start(&rpr_cli, &srv, uuid, timeout, max_devs, &status); The above example shows pseudo code for starting a scan procedure on the target Remote Provisioning Server node. This procedure will start a ten-second, multiple-device scanning where the generated scan report will contain a maximum of three unprovisioned devices. If the UUID argument was specified, the same procedure would only scan for the device with the corresponding UUID. After the procedure completes, the server sends the scan report that will be handled in the client's :c:member:`bt_mesh_rpr_cli.scan_report` callback. Additionally, the Remote Provisioning Client model also supports extended scanning with the :c:func:`bt_mesh_rpr_scan_start_ext` call. Extended scanning supplements regular scanning by allowing the Remote Provisioning Server to report additional data for a specific device. The Remote Provisioning Server will use active scanning to request a scan response from the unprovisioned device if it is supported by the unprovisioned device. Provisioning ********* The Remote Provisioning Client starts a provisioning procedure by using the :c:func:`bt_mesh_provision_remote` call: .. code-block:: C struct bt_mesh_rpr_cli rpr_cli; const struct bt_mesh_rpr_node srv = { .addr = 0x0004, .net_idx = 0, .ttl = BT_MESH_TTL_DEFAULT, }; uint8_t uuid[16] = { 0xaa }; uint16_t addr = 0x0006; uint16_t net_idx = 0; bt_mesh_provision_remote(&rpr_cli, &srv, uuid, net_idx, addr); The above example shows pseudo code for remotely provisioning a device through a Remote Provisioning Server node. This procedure will attempt to provision the device with the corresponding UUID, and assign the address 0x0006 to its primary element using the network key located at index zero. .. note:: During the remote provisioning, the same :c:struct:`bt_mesh_prov` callbacks are triggered as for ordinary provisioning. See section :ref:`bluetooth_mesh_provisioning` for further details. Re-provisioning ************* In addition to scanning and provisioning functionality, the Remote Provisioning Client also provides means to reconfigure node addresses, device keys and Composition Data on devices that support the :ref:`bluetooth_mesh_models_rpr_srv` model. This is provided through the Node Provisioning Protocol Interface (NPPI) which supports the following three procedures: * Device Key Refresh procedure: Used to change the device key of the Target node without a need to reconfigure the node. * Node Address Refresh procedure: Used to change the nodes device key and unicast address. * Node Composition Refresh procedure: Used to change the device key of the node, and to add or delete models or features of the node. The three NPPI procedures can be initiated with the :c:func:`bt_mesh_reprovision_remote` call: .. code-block:: C struct bt_mesh_rpr_cli rpr_cli; struct bt_mesh_rpr_node srv = { .addr = 0x0006, .net_idx = 0, .ttl = BT_MESH_TTL_DEFAULT, }; bool composition_changed = false; uint16_t new_addr = 0x0009; bt_mesh_reprovision_remote(&rpr_cli, &srv, new_addr, composition_changed); The above example shows pseudo code for triggering a Node Address Refresh procedure on the Target node. The specific procedure is not chosen directly, but rather through the other parameters that are inputted. In the example we can see that the current unicast address of the Target is 0x0006, while the new address is set to 0x0009. If the two addresses were the same, and the ``composition_changed`` flag was set to true, this code would instead trigger a Node Composition Refresh procedure. If the two addresses were the same, and the ``composition_changed`` flag was set to false, this code would trigger a Device Key Refresh procedure.

The model is enabled if the node has the :ref:`bluetooth_mesh_od_srv` enabled. The Solicitation PDU RPL Configuration Server model was introduced in the Bluetooth Mesh Protocol Specification version 1.1, and manages the Solicitation Replay Protection List (SRPL) saved on the device. The SRPL is used to reject Solicitation PDUs that are already processed by a node. When a valid Solicitation PDU message is successfully processed by a node, the SSRC field and SSEQ field of the message are stored in the node's SRPL. The Solicitation PDU RPL Configuration Server does not have an API of its own, and relies on a :ref:`bluetooth_mesh_srpl_cli` to control it.

```restructuredtext .. _bt_mesh_proxy: Proxy ##### The Proxy feature allows legacy devices like phones to access the Bluetooth Mesh network through GATT. The Proxy feature is only compiled in if the :kconfig:option:`CONFIG_BT_MESH_GATT_PROXY` option is set. The Proxy feature state is controlled by the :ref:`bluetooth_mesh_models_cfg_srv`, and the initial value can be set with :c:member:`bt_mesh_cfg_srv.gatt_proxy`. Nodes with the Proxy feature enabled can advertise with Network Identity and Node Identity, which is controlled by the :ref:`bluetooth_mesh_models_cfg_cli`. The GATT Proxy state indicates if the Proxy feature is supported. Private Proxy *********** A node supporting the Proxy feature and the :ref:`bluetooth_mesh_models_priv_beacon_srv` model can advertise with Private Network Identity and Private Node Identity types, which is controlled by the :ref:`bluetooth_mesh_models_priv_beacon_cli`. By advertising with this set of identification types, the node allows the legacy device to connect to the network over GATT while maintaining the privacy of the network. The Private GATT Proxy state indicates whether the Private Proxy functionality is supported. Proxy Solicitation ************** In the case where both GATT Proxy and Private GATT Proxy states are disabled on a node, a legacy device cannot connect to it. A node supporting the :ref:`bluetooth_mesh_od_srv` may however be solicited to advertise connectable advertising events without enabling the Private GATT Proxy state. To solicit the node, the legacy device can send a Solicitation PDU by calling the :func:`bt_mesh_proxy_solicit` function. To enable this feature, the device must to be compiled with the :kconfig:option:`CONFIG_BT_MESH_PROXY_SOLICITATION` option set. Solicitation PDUs are non-mesh, non-connectable, undirected advertising messages containing Proxy Solicitation UUID, encrypted with the network key of the subnet that the legacy device wants to connect to. The PDU contains the source address of the legacy device and a sequence number. The sequence number is maintained by the legacy device and is incremented for every new Solicitation PDU sent. Each node supporting the Solicitation PDU reception holds its own Solicitation Replay Protection List (SRPL). The SRPL protects the solicitation mechanism from replay attacks by storing solicitation sequence number (SSEQ) and solicitation source (SSRC) pairs of valid Solicitation PDUs processed by the node. The delay between updating the SRPL and storing the change to the persistent storage is defined by :kconfig:option:`CONFIG_BT_MESH_RPL_STORE_TIMEOUT`. The Solicitation PDU RPL Configuration models, :ref:`bluetooth_mesh_srpl_cli` and :ref:`bluetooth_mesh_srpl_srv`, provide the functionality of saving and clearing SRPL entries. A node that supports the Solicitation PDU RPL Configuration Client model can clear a section of the SRPL on the target by calling the :func:`bt_mesh_sol_pdu_rpl_clear` function. Communication between the Solicitation PDU RPL Configuration Client and Server is encrypted using the application key, therefore, the Solicitation PDU RPL Configuration Client can be instantiated on any device in the network. When the node receives the Solicitation PDU and successfully authenticates it, it will start advertising connectable advertisements with the Private Network Identity type. The duration of the advertisement can be configured by the On-Demand Private Proxy Client model.

```restructuredtext .. _bluetooth_mesh_models_rpr_srv: Remote Provisioning Server ########################## The Remote Provisioning Server model is a foundation model defined by the Bluetooth mesh specification. It is enabled with the :kconfig:option:`CONFIG_BT_MESH_RPR_SRV` option. The Remote Provisioning Server model is introduced in the Bluetooth Mesh Protocol Specification version 1.1, and is used to support the functionality of remotely provisioning devices into a mesh network. The Remote Provisioning Server does not have an API of its own, but relies on a :ref:`bluetooth_mesh_models_rpr_cli` to control it. The Remote Provisioning Server model only accepts messages encrypted with the node's device key. If present, the Remote Provisioning Server model must be instantiated on the primary element. Note that after refreshing the device key, node address or Composition Data through a Node Provisioning Protocol Interface (NPPI) procedure, the :c:member:`bt_mesh_prov.reprovisioned` callback is triggered. See section :ref:`bluetooth_mesh_models_rpr_cli` for further details. Limitations ----------- The following limitations apply to Remote Provisioning Server model: * Provisioning of unprovisioned device using PB-GATT is not supported. * All Node Provisioning Protocol Interface (NPPI) procedures are supported. However, if the composition data of a device gets changed after device firmware update (see :ref:`firmware effect <bluetooth_mesh_dfu_firmware_effect>`), it is not possible for the device to remain provisioned. The device should be unprovisioned if its composition data is expected to change.

```restructuredtext .. _bluetooth_mesh_access: Access layer ############ The access layer is the application's interface to the Bluetooth Mesh network. The access layer provides mechanisms for compartmentalizing the node behavior into elements and models, which are implemented by the application. Mesh models *********** The functionality of a mesh node is represented by models. A model implements a single behavior the node supports, like being a light, a sensor or a thermostat. The mesh models are grouped into elements. Each element is assigned its own unicast address, and may only contain one of each type of model. Conventionally, each element represents a single aspect of the mesh node behavior. For instance, a node that contains a sensor, two lights and a power outlet would spread this functionality across four elements, with each element instantiating all the models required for a single aspect of the supported behavior. The node's element and model structure is specified in the node composition data, which is passed to :c:func:`bt_mesh_init` during initialization. The Bluetooth SIG have defined a set of foundation models (see :ref:`bluetooth_mesh_models`) and a set of models for implementing common behavior in the `Bluetooth Mesh Model Specification <path_to_url`_. All models not specified by the Bluetooth SIG are vendor models, and must be tied to a Company ID. Mesh models have several parameters that can be configured either through initialization of the mesh stack or with the :ref:`bluetooth_mesh_models_cfg_srv`: Opcode list =========== The opcode list contains all message opcodes the model can receive, as well as the minimum acceptable payload length and the callback to pass them to. Models can support any number of opcodes, but each opcode can only be listed by one model in each element. The full opcode list must be passed to the model structure in the composition data, and cannot be changed at runtime. The end of the opcode list is determined by the special :c:macro:`BT_MESH_MODEL_OP_END` entry. This entry must always be present in the opcode list, unless the list is empty. In that case, :c:macro:`BT_MESH_MODEL_NO_OPS` should be used in place of a proper opcode list definition. AppKey list =========== The AppKey list contains all the application keys the model can receive messages on. Only messages encrypted with application keys in the AppKey list will be passed to the model. The maximum number of supported application keys each model can hold is configured with the :kconfig:option:`CONFIG_BT_MESH_MODEL_KEY_COUNT` configuration option. The contents of the AppKey list is managed by the :ref:`bluetooth_mesh_models_cfg_srv`. Subscription list ================= A model will process all messages addressed to the unicast address of their element (given that the utilized application key is present in the AppKey list). Additionally, the model will process packets addressed to any group or virtual address in its subscription list. This allows nodes to address multiple nodes throughout the mesh network with a single message. The maximum number of supported addresses in the Subscription list each model can hold is configured with the :kconfig:option:`CONFIG_BT_MESH_MODEL_GROUP_COUNT` configuration option. The contents of the subscription list is managed by the :ref:`bluetooth_mesh_models_cfg_srv`. Model publication ================= The models may send messages in two ways: * By specifying a set of message parameters in a :c:struct:`bt_mesh_msg_ctx`, and calling :c:func:`bt_mesh_model_send`. * By setting up a :c:struct:`bt_mesh_model_pub` structure and calling :c:func:`bt_mesh_model_publish`. When publishing messages with :c:func:`bt_mesh_model_publish`, the model will use the publication parameters configured by the :ref:`bluetooth_mesh_models_cfg_srv`. This is the recommended way to send unprompted model messages, as it passes the responsibility of selecting message parameters to the network administrator, which likely knows more about the mesh network than the individual nodes will. To support publishing with the publication parameters, the model must allocate a packet buffer for publishing, and pass it to :c:member:`bt_mesh_model_pub.msg`. The Config Server may also set up period publication for the publication message. To support this, the model must populate the :c:member:`bt_mesh_model_pub.update` callback. The :c:member:`bt_mesh_model_pub.update` callback will be called right before the message is published, allowing the model to change the payload to reflect its current state. By setting :c:member:`bt_mesh_model_pub.retr_update` to 1, the model can configure the :c:member:`bt_mesh_model_pub.update` callback to be triggered on every retransmission. This can, for example, be used by models that make use of a Delay parameter, which can be adjusted for every retransmission. The :c:func:`bt_mesh_model_pub_is_retransmission` function can be used to differentiate a first publication and a retransmission. The :c:macro:`BT_MESH_PUB_MSG_TOTAL` and :c:macro:`BT_MESH_PUB_MSG_NUM` macros can be used to return total number of transmissions and the retransmission number within one publication interval. Extended models =============== The Bluetooth Mesh specification allows the mesh models to extend each other. When a model extends another, it inherits that model's functionality, and extension can be used to construct complex models out of simple ones, leveraging the existing model functionality to avoid defining new opcodes. Models may extend any number of models, from any element. When one model extends another in the same element, the two models will share subscription lists. The mesh stack implements this by merging the subscription lists of the two models into one, combining the number of subscriptions the models can have in total. Models may extend models that extend others, creating an "extension tree". All models in an extension tree share a single subscription list per element it spans. Model extensions are done by calling :c:func:`bt_mesh_model_extend` during initialization. A model can only be extended by one other model, and extensions cannot be circular. Note that binding of node states and other relationships between the models must be defined by the model implementations. The model extension concept adds some overhead in the access layer packet processing, and must be explicitly enabled with :kconfig:option:`CONFIG_BT_MESH_MODEL_EXTENSIONS` to have any effect. Model data storage ================== Mesh models may have data associated with each model instance that needs to be stored persistently. The access API provides a mechanism for storing this data, leveraging the internal model instance encoding scheme. Models can store one user defined data entry per instance by calling :c:func:`bt_mesh_model_data_store`. To be able to read out the data the next time the device reboots, the model's :c:member:`bt_mesh_model_cb.settings_set` callback must be populated. This callback gets called when model specific data is found in the persistent storage. The model can retrieve the data by calling the ``read_cb`` passed as a parameter to the callback. See the :ref:`settings_api` module documentation for details. When model data changes frequently, storing it on every change may lead to increased wear of flash. To reduce the wear, the model can postpone storing of data by calling :c:func:`bt_mesh_model_data_store_schedule`. The stack will schedule a work item with delay defined by the :kconfig:option:`CONFIG_BT_MESH_STORE_TIMEOUT` option. When the work item is running, the stack will call the :c:member:`bt_mesh_model_cb.pending_store` callback for every model that has requested storing of data. The model can then call :c:func:`bt_mesh_model_data_store` to store the data. If :kconfig:option:`CONFIG_BT_MESH_SETTINGS_WORKQ` is enabled, the :c:member:`bt_mesh_model_cb.pending_store` callback is called from a dedicated thread. This allows the stack to process other incoming and outgoing messages while model data is being stored. It is recommended to use this option and the :c:func:`bt_mesh_model_data_store_schedule` function when large amount of data needs to be stored. Composition Data ================ The Composition Data provides information about a mesh device. A device's Composition Data holds information about the elements on the device, the models that it supports, and other features. The Composition Data is split into different pages, where each page contains specific feature information about the device. In order to access this information, the user may use the :ref:`bluetooth_mesh_models_cfg_srv` model or, if supported, the :ref:`bluetooth_mesh_lcd_srv` model. Composition Data Page 0 ----------------------- Composition Data Page 0 provides the fundamental information about a device, and is mandatory for all mesh devices. It contains the element and model composition, the supported features, and manufacturer information. Composition Data Page 1 ----------------------- Composition Data Page 1 provides information about the relationships between models, and is mandatory for all mesh devices. A model may extend and/or correspond to one or more models. A model can extend another model by calling :c:func:`bt_mesh_model_extend`, or correspond to another model by calling :c:func:`bt_mesh_model_correspond`. :kconfig:option:`CONFIG_BT_MESH_MODEL_EXTENSION_LIST_SIZE` specifies how many model relations can be stored in the composition on a device, and this number should reflect the number of :c:func:`bt_mesh_model_extend` and :c:func:`bt_mesh_model_correspond` calls. Composition Data Page 2 ----------------------- Composition Data Page 2 provides information for supported mesh profiles. Mesh profile specifications define product requirements for devices that want to support a specific Bluetooth SIG defined profile. Currently supported profiles can be found in section 3.12 in `Bluetooth SIG Assigned Numbers <path_to_url`_. Composition Data Page 2 is only mandatory for devices that claim support for one or more mesh profile(s). Composition Data Pages 128, 129 and 130 --------------------------------------- Composition Data Pages 128, 129 and 130 mirror Composition Data Pages 0, 1 and 2 respectively. They are used to represent the new content of the mirrored pages when the Composition Data will change after a firmware update. See :ref:`bluetooth_mesh_dfu_srv_comp_data_and_models_metadata` for details. Delayable messages ================== The delayable message functionality is enabled with Kconfig option :kconfig:option:`CONFIG_BT_MESH_ACCESS_DELAYABLE_MSG`. This is an optional functionality that implements specification recommendations for messages that are transmitted by a model in a response to a received message, also called response messages. Response messages should be sent with the following random delays: * Between 20 and 50 milliseconds if the received message was sent to a unicast address * Between 20 and 500 milliseconds if the received message was sent to a group or virtual address The delayable message functionality is triggered if the :c:member:`bt_mesh_msg_ctx.rnd_delay` flag is set. The delayable message functionality stores messages in the local memory while they are waiting for the random delay expiration. If the transport layer doesn't have sufficient memory to send a message at the moment the random delay expires, the message is postponed for another 10 milliseconds. If the transport layer cannot send a message for any other reason, the delayable message functionality raises the :c:member:`bt_mesh_send_cb.start` callback with a transport layer error code. If the delayable message functionality cannot find enough free memory to store an incoming message, it will send messages with delay close to expiration to free memory. When the mesh stack is suspended or reset, messages not yet sent are removed and the :c:member:`bt_mesh_send_cb.start` callback is raised with an error code. .. note:: When a model sends several messages in a row, it may happen that the messages are not sent in the order they were passed to the access layer. This is because some messages can be delayed for a longer time than the others. Disable the randomization by setting the :c:member:`bt_mesh_msg_ctx.rnd_delay` to ``false``, when a set of messages originated by the same model needs to be sent in a certain order. Delayable publications ====================== The delayable publication functionality implements the specification recommendations for message publication delays in the following cases: * Between 20 to 500 milliseconds when the Bluetooth Mesh stack starts or when the publication is triggered by the :c:func:`bt_mesh_model_publish` function * Between 20 to 50 milliseconds for periodically published messages This feature is optional and enabled with the :kconfig:option:`CONFIG_BT_MESH_DELAYABLE_PUBLICATION` Kconfig option. When enabled, each model can enable or disable the delayable publication by setting the :c:member:`bt_mesh_model_pub.delayable` bit field to ``1`` or ``0`` correspondingly. This bit field can be changed at any time.

```restructuredtext Bluetooth: Broadcast Audio Profile Broadcast Assistant ###################################################### This document describes how to run the BAP Broadcast Assistant functionality. Note that in the examples below, some lines of debug have been removed to make this shorter and provide a better overview. The Broadcast Assistant is responsible for offloading scan for a resource restricted device, such that scanning does not drain the battery. The Broadcast Assistant shall support scanning for periodic advertisements and may optionally support the periodic advertisements synchronization transfer (PAST) protocol. The Broadcast Assistant will typically be phones or laptops. The Broadcast Assistant scans for periodic advertisements and transfer information to the server. It is necessary to have :kconfig:option:`CONFIG_BT_BAP_BROADCAST_ASSISTANT_LOG_LEVEL_DBG` enabled for using the Broadcast Assistant interactively. When the Bluetooth stack has been initialized (:code:`bt init`), and a device has been connected, the Broadcast Assistant can discover BASS on the connected device calling :code:`bap_broadcast_assistant discover`, which will start a discovery for the BASS UUIDs and store the handles, and subscribe to all notifications. .. code-block:: console uart:~$ bap_broadcast_assistant --help bap_broadcast_assistant - Bluetooth BAP broadcast assistant client shell commands Subcommands: discover : Discover BASS on the server scan_start : Start scanning for broadcasters scan_stop : Stop scanning for BISs add_src : Add a source <address: XX:XX:XX:XX:XX:XX> <type: public/random> <adv_sid> <sync_pa> <broadcast_id> [<pa_interval>] [<sync_bis>] [<metadata>] add_broadcast_id : Add a source by broadcast ID <broadcast_id> <sync_pa> [<sync_bis>] [<metadata>] add_pa_sync : Add a PA sync as a source <sync_pa> <broadcast_id> [bis_index [bis_index [bix_index [...]]]]> mod_src : Set sync <src_id> <sync_pa> [<pa_interval> \| "unknown"] [<sync_bis>] [<metadata>] broadcast_code : Send a string-based broadcast code of up to 16 bytes <src_id> <broadcast code> rem_src : Remove a source <src_id> read_state : Remove a source <index> Example usage ************* Setup ===== .. code-block:: console uart:~$ bt init uart:~$ bap init uart:~$ bt connect xx:xx:xx:xx:xx:xx public When connected ============== Start scanning for periodic advertisements for a server: -------------------------------------------------------- .. note:: The Broadcast Assistant will not actually start scanning for periodic advertisements, as that feature is still, at the time of writing, not implemented. .. code-block:: console uart:~$ bap_broadcast_assistant discover BASS discover done with 1 recv states uart:~$ bap_broadcast_assistant scan_start true BASS scan start successful Found broadcaster with ID 0x05BD38 and addr 1E:4D:0A:AA:6E:49 (random) and sid 0x00 Adding a source to the receive state with add_src: -------------------------------------------------- .. code-block:: console uart:~$ bap_broadcast_assistant add_src 11:22:33:44:55:66 public 5 1 1 BASS recv state: src_id 0, addr 11:22:33:44:55:66 (public), sid 5, sync_state 1, encrypt_state 000000000000000000000000000000000 [0]: BIS sync 0, metadata_len 0 Adding a source to the receive state with add_broadcast_id (recommended): your_sha256_hash--------- .. code-block:: console uart:~$ bap_broadcast_assistant add_broadcast_id 0x05BD38 true [DEVICE]: 1E:4D:0A:AA:6E:49 (random), AD evt type 5, RSSI -28 Broadcast Audio Source C:0 S:0 D:0 SR:0 E:1 Prim: LE 1M, Secn: LE 2M, Interval: 0x03c0 (1200000 us), SID: 0x0 Found BAP broadcast source with address 1E:4D:0A:AA:6E:49 (random) and ID 0x05BD38 BASS recv state: src_id 0, addr 1E:4D:0A:AA:6E:49 (random), sid 0, sync_state 0, encrypt_state 0 [0]: BIS sync 0x0000, metadata_len 0 BASS add source successful BASS recv state: src_id 0, addr 1E:4D:0A:AA:6E:49 (random), sid 0, sync_state 2, encrypt_state 0 [0]: BIS sync 0x0000, metadata_len 0 BASS recv state: src_id 0, addr 1E:4D:0A:AA:6E:49 (random), sid 0, sync_state 2, encrypt_state 0 [0]: BIS sync 0x0000, metadata_len 4 Metadata length 2, type 2, data: 0100 Modifying a receive state: -------------------------- .. code-block:: console uart:~$ bap_broadcast_assistant mod_src 0 true 0x03c0 0x02 BASS modify source successful BASS recv state: src_id 0, addr 1E:4D:0A:AA:6E:49 (random), sid 0, sync_state 2, encrypt_state 0 [0]: BIS sync 0x0001, metadata_len 4 Metadata length 2, type 2, data: 0100 Supplying a broadcast code: --------------------------- .. code-block:: console uart:~$ bap_broadcast_assistant broadcast_code 0 secretCode Sending broadcast code: 00000000: 73 65 63 72 65 74 43 6f 64 65 00 00 00 00 00 00 \|secretCo de....\| uart:~$ BASS broadcast code successful ```	/content/code_sandbox/doc/connectivity/bluetooth/api/audio/shell/bap_broadcast_assistant.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	1,415

```restructuredtext Media control for Generic Audio Content Control ############################################### This document describes how to run the media control functionality, using the shell, both as a client and as a server. The media control server consists of to parts. There is a media player (mpl) that contains the logic to handle media, and there is a media control service (mcs) that serves as a GATT-based interface to the player. The media control client consists of one part, the GATT based client (mcc). The media control server may include an object transfer service (ots) and the media control client may include an object transfer client (otc). When these are included, a richer set of functionality is available. The media control server and client both implement the Generic Media Control Service (only), and do not use any underlying Media Control Services. Note that in the examples below, in many cases the debug output has been removed and long outputs may have been shortened to make the examples shorter and clearer. Also note that this documentation does not list all shell commands, it just shows examples of some of them. The set of commands is explorable from the mcc shell and the mpl shell, by typing :code:`mcc` or :code:`mpl` and pressing TAB. A help text for each command can be found by doing :samp:`mcc {<command>} help` or :samp:`mpl {<command>} help`. Overview ******** A media player has a name and an icon that allows identification of the player for the user. The content of the media player is structured into tracks and groups. A media player has a number of groups. A group contains tracks and other groups. (In this implementation, a group only contains tracks, not other groups.) Tracks can be divided into segments. An active player will have a current track. This is the track that is playing now (if the player is playing). The current track has a title, a duration (given in hundredths of a second) and a position - the current position of the player within the track. There is also a current group (the group of the current track), a parent group (the parent group of the current group) and a next track. The media player is in a state, which will be one of playing, paused, seeking or inactive. When playing, playback happens at a given playback speed, and the tracks are played according to the playing order, which is one of the playing orders supported. Track changes are signalled as notifications of the track changed characteristic. When seeking (fast forward or fast rewind), the track position is moved according to the seeking speed. The opcodes supported tells which operations are supported by the player by writing to the media control point. There is also a search control point that allows to search for groups and tracks according to various criteria, with the result returned in the search results. Finally, the content control ID is used to associate the media player with an audio stream. Media Control Client (MCP) ************************ The media control client is used to control, and to get information from, a media control server. Control is done by writing to one of the two control points, or by writing to other writable characteristics. Getting information is done by reading characteristics, or by configuring the server to send notifications. Using the media control client ============================== Before use, the media control client must be initialized by the command :code:`mcc init`. To achieve a connection to the peer, the :code:`bt` commands must be used - :code:`bt init` followed by :code:`bt advertise on` (or :code:`bt connect` if the server is advertising). When the media control client is connected to a media control server, the client can discover the server's Generic Media Control Service, by giving the command :code:`mcc discover_mcs`. This will store the handles of the service, and (optionally, but default) subscribe to all notifications. After discovery, the media control client can read and write characteristics, including the media control point and the search control point.

Some operations (e.g. goto track) take an argument. Currently, raw opcode values are used as input to the control point shell command. These opcode values can be found in the mpl.h header file. Send the play command (opcode "1"), the command to go to track (opcode "52") number three, and the pause command (opcode "2"): .. code-block:: console uart:~$ mcc set_cp 1 Media State: 1 Operation: 1, result: 1 Operation: 1, param: 0 uart:~$ mcc set_cp 52 3 Track changed Track title: Interlude #3 (Levanto Seventy) Track duration: 7800 Track Position: 0 Current Track Object ID: 0x000000000104 Next Track Object ID: 0x000000000105 Operation: 52, result: 1 Operation: 52, param: 3 uart:~$ mcc set_cp 2 Media State: 2 Operation: 2, result: 1 Operation: 2, param: 0 Using the included object transfer client ----------------------------------------- When object transfer is supported by both the client and the server, a larger set of characteristics is available.

If the result is successful, the search results are stored in an object in the object transfer service. The ID of the search results ID object can be read from the search results object ID characteristic. The search result object can then be downloaded as for the current group object above. (Note that the search results object ID is empty until a search has been done.) This implementation has a working implementation of the search functionality interface and the server-side search control point parameter parsing. But the actual searching is faked, the same results are returned no matter what is searched for. There are two commands for search, one (:code:`mcc set_scp_raw`) allows to input the search control point parameter (the sequence of search control items) as a string. The other (:code:`mcc set_scp_ioptest`) does preset IOP test searches and takes the round number of the IOP search control point test as a parameter. Before the search, the search results object ID is empty .. code-block:: console uart:~$ mcc read_search_results_obj_id Search Results Object ID: 0x000000000000 <dbg> bt_mcc.mcc_read_search_results_obj_id_cb: Zero-length Search Results Object ID Run the search corresponding to the fourth round of the IOP test: The search control point parameter generated by this command and parameter has one search control item. The length field (first octet) is 16 (0x10). (The length of the length field itself is not included.) The type field (second octet) is 0x04 (search for a group name). The parameter (the group name to search for) is "TSPX_Group_Name". .. code-block:: console uart:~$ mcc set_scp_ioptest 4 Search string: 00000000: 10 04 54 53 50 58 5f 47 72 6f 75 70 5f 4e 61 6d \|..TSPX_G roup_Nam\| 00000010: 65 \|e \| Search control point notification result code: 1 Search Results Object ID: 0x000000000107 Search Control Point set After the successful search, the search results object ID has a value: .. code-block:: console uart:~$ mcc read_search_results_obj_id Search Results Object ID: 0x000000000107 Media Control Service (MCS) ************************* The media control service (mcs) and the associated media player (mpl) typically reside on devices that can provide access to, and serve, media content, like PCs and smartphones. As mentioned above, the media player (mpl) has the player logic, while the media control service (mcs) has the GATT-based interface. This separation is done so that the media player can also be used without the GATT-based interface. Using the media control service and the media player ==================================================== The media control service and the media player are in general controlled remotely, from the media control client. Before use, the media control client must be initialized by the command :code:`mpl init`. As for the client, the :code:`bt` commands are used for connecting - :code:`bt init` followed by :code:`bt connect <address> <address type>` (or :code:`bt advertise on` if the server is advertising). Example Usage ============= Setup ----- .. code-block:: console uart:~$ bt init Bluetooth initialized uart:~$ mpl init [Large amounts of debug output] uart:~$ bt connect F9:33:3B:67:D2:A7 (random) Connection pending Connected: F9:33:3B:67:D2:A7 (random) When connected -------------- Control is done from the client. The server will give debug output related to the various operations performed by the client. Example: Debug output by the server when the client gives the "next track" command: .. code-block:: console [00:13:29.932,373] <dbg> bt_mcs.control_point_write: Opcode: 49 [00:13:29.932,403] <dbg> bt_mpl.mpl_operation_set: opcode: 49, param: 536880068 [00:13:29.932,403] <dbg> bt_mpl.paused_state_operation_handler: Operation opcode: 49 [00:13:29.932,495] <dbg> bt_mpl.do_next_track: Track ID before: 0x000000000104 [00:13:29.932,586] <dbg> bt_mpl.do_next_track: Track ID after: 0x000000000105 [00:13:29.932,617] <dbg> bt_mcs.mpl_track_changed_cb: Notifying track change [00:13:29.932,708] <dbg> bt_mcs.mpl_track_title_cb: Notifying track title: Interlude #4 (Vesper Dreams) [00:13:29.932,800] <dbg> bt_mcs.mpl_track_duration_cb: Notifying track duration: 13500 [00:13:29.932,861] <dbg> bt_mcs.mpl_track_position_cb: Notifying track position: 0 [00:13:29.933,044] <dbg> bt_mcs.mpl_current_track_id_cb: Notifying current track ID: 0x000000000105 [00:13:29.933,258] <dbg> bt_mcs.mpl_next_track_id_cb: Notifying next track ID: 0x000000000106 [00:13:29.933,380] <dbg> bt_mcs.mpl_operation_cb: Notifying control point - opcode: 49, result: 1 Some server commands are available. These commands force notifications of the various characteristics, for testing that the client receives notifications. The values sent in the notifications caused by these testing commands are independent of the media player, so they do not correspond the actual values of the characteristics nor to the actual state of the media player. Example: Force (fake value) notification of the track duration: .. code-block:: console uart:~$ mpl duration_changed_cb [00:15:17.491,058] <dbg> bt_mcs.mpl_track_duration_cb: Notifying track duration: 12000 ```	/content/code_sandbox/doc/connectivity/bluetooth/api/audio/shell/mcp.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	4,289

```restructuredtext Bluetooth: Call Control Profile ############################### This document describes how to run the call control functionality, both as a client and as a (telephone bearer service (TBS)) server. Note that in the examples below, some lines of debug have been removed to make this shorter and provide a better overview. Telephone Bearer Service Client ***************************** The telephone bearer service client will typically exist on a resource restricted device, such as headphones, but may also exist on e.g. phones or laptops. The call control client will also thus typically be the advertiser. The client can control the states of calls on a server using the call control point. It is necessary to have :kconfig:option:`CONFIG_BT_TBS_CLIENT_LOG_LEVEL_DBG` enabled for using the client interactively. Using the telephone bearer service client ========================================= When the Bluetooth stack has been initialized (:code:`bt init`), and a device has been connected, the telephone bearer service client can discover TBS on the connected device calling :code:`tbs_client discover`, which will start a discovery for the TBS UUIDs and store the handles, and optionally subscribe to all notifications (default is to subscribe to all). Since a server may have multiple TBS instances, most of the tbs_client commands will take an index (starting from 0) as input. Joining calls require at least 2 call IDs, and all call indexes shall be on the same TBS instance. A server may also have a GTBS instance, which is an abstraction layer for all the telephone bearers on the server. If the server has both GTBS and TBS, the client may subscribe and use either when sending requests if :code:`BT_TBS_CLIENT_GTBS` is enabled. .. code-block:: console tbs_client --help tbs_client - Bluetooth TBS_CLIENT shell commands Subcommands: discover :Discover TBS [subscribe] set_signal_reporting_interval :Set the signal reporting interval [<{instance_index, gtbs}>] <interval> originate :Originate a call [<{instance_index, gtbs}>] <uri> terminate :terminate a call [<{instance_index, gtbs}>] <id> accept :Accept a call [<{instance_index, gtbs}>] <id> hold :Place a call on hold [<{instance_index, gtbs}>] <id> retrieve :Retrieve a held call [<{instance_index, gtbs}>] <id> read_provider_name :Read the bearer name [<{instance_index, gtbs}>] read_bearer_uci :Read the bearer UCI [<{instance_index, gtbs}>] read_technology :Read the bearer technology [<{instance_index, gtbs}>] read_uri_list :Read the bearer's supported URI list [<{instance_index, gtbs}>] read_signal_strength :Read the bearer signal strength [<{instance_index, gtbs}>] read_signal_interval :Read the bearer signal strength reporting interval [<{instance_index, gtbs}>] read_current_calls :Read the current calls [<{instance_index, gtbs}>] read_ccid :Read the CCID [<{instance_index, gtbs}>] read_status_flags :Read the in feature and status value [<{instance_index, gtbs}>] read_uri :Read the incoming call target URI [<{instance_index, gtbs}>] read_call_state :Read the call state [<{instance_index, gtbs}>] read_remote_uri :Read the incoming remote URI [<{instance_index, gtbs}>] read_friendly_name :Read the friendly name of an incoming call [<{instance_index, gtbs}>] read_optional_opcodes :Read the optional opcodes [<{instance_index, gtbs}>] In the following examples, notifications from GTBS is ignored, unless otherwise specified.

It is necessary to have :kconfig:option:`CONFIG_BT_TBS_LOG_LEVEL_DBG` enabled for using the TBS server interactively. Using the telephone bearer service ================================== TBS can be controlled locally, or by a remote device (when in a call). For example a remote device may initiate a call to the device with the TBS server, or the TBS server may initiate a call to remote device, without a TBS_CLIENT client. The TBS implementation is capable of fully controlling any call. .. code-block:: console tbs --help tbs - Bluetooth TBS shell commands Subcommands: init :Initialize TBS authorize :Authorize the current connection accept :Accept call <call_index> terminate :Terminate call <call_index> hold :Hold call <call_index> retrieve :Retrieve call <call_index> originate :Originate call [<instance_index>] <uri> join :Join calls <id> <id> [<id> [<id> [...]]] incoming :Simulate incoming remote call [<{instance_index, gtbs}>] <local_uri> <remote_uri> <remote_friendly_name> remote_answer :Simulate remote answer outgoing call <call_index> remote_retrieve :Simulate remote retrieve <call_index> remote_terminate :Simulate remote terminate <call_index> remote_hold :Simulate remote hold <call_index> set_bearer_provider_name :Set the bearer provider name [<{instance_index, gtbs}>] <name> set_bearer_technology :Set the bearer technology [<{instance_index, gtbs}>] <technology> set_bearer_signal_strength :Set the bearer signal strength [<{instance_index, gtbs}>] <strength> set_status_flags :Set the bearer feature and status value [<{instance_index, gtbs}>] <feature_and_status> set_uri_scheme :Set the URI prefix list <bearer_idx> <uri1 [uri2 [uri3 [...]]]> print_calls :Output all calls in the debug log Example Usage ============= Setup ----- .. code-block:: console uart:~$ bt init uart:~$ bt connect xx:xx:xx:xx:xx:xx public When connected -------------- Answering a call for a peer device originated by a client: .. code-block:: console <dbg> bt_tbs.write_call_cp: Index 0: Processing the originate opcode <dbg> bt_tbs.originate_call: New call with call index 1 <dbg> bt_tbs.write_call_cp: Index 0: Processed the originate opcode with status success for call index 1 uart:~$ tbs remote_answer 1 TBS succeeded for call_id: 1 Incoming call from a peer device, accepted by client: .. code-block:: console uart:~$ tbs incoming 0 tel:123 tel:456 Peter TBS succeeded for call_id: 4 <dbg> bt_tbs.bt_tbs_remote_incoming: New call with call index 4 <dbg> bt_tbs.write_call_cp: Index 0: Processed the accept opcode with status success for call index 4 ```	/content/code_sandbox/doc/connectivity/bluetooth/api/audio/shell/ccp.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	2,414
```restructuredtext Bluetooth: Coordinated Set Identification Profile ################################################# This document describes how to run the coordinated set identification functionality, both as a client and as a server. Note that in the examples below, some lines of debug have been removed to make this shorter and provide a better overview. Set Coordinator (Client) ********************** The client will typically be a resource-rich device, such as a smartphone or a laptop. The client is able to lock and release members of a coordinated set. While the coordinated set is locked, no other clients may lock the set. To lock a set, the client must connect to each of the set members it wants to lock. This implementation will always try to connect to all the members of the set, and at the same time. Thus if the set size is 3, then :code:`BT_MAX_CONN` shall be at least 3. If the locks on set members shall persists through disconnects, it is necessary to bond with the set members. If you need to bond with multiple set members, make sure that :code:`BT_MAX_PAIRED` is correctly configured. Using the Set Coordinator ========================= When the Bluetooth stack has been initialized (:code:`bt init`), and a set member device has been connected, the call control client can be initialized by calling :code:`csip_set_coordinator init`, which will start a discovery for the TBS uuids and store the handles, and optionally subscribe to all notifications (default is to subscribe to all). Once the client has connected and discovered the handles, then it can read the set information, which is needed to identify other set members. The client can then scan for and connect to the remaining set members, and once all the members has been connected to, it can lock and release the set. It is necessary to enable :kconfig:option:`CONFIG_BT_CSIP_SET_COORDINATOR_LOG_LEVEL_DBG` to properly use the set coordinator. .. code-block:: console csip_set_coordinator --help csip_set_coordinator - Bluetooth CSIP_SET_COORDINATOR shell commands Subcommands: init :Initialize CSIP_SET_COORDINATOR discover :Run discover for CSIS on peer device [member_index] discover_members :Scan for set members <set_pointer> lock_set :Lock set release_set :Release set lock :Lock specific member [member_index] release :Release specific member [member_index] lock_get :Get the lock value of the specific member and instance [member_index [inst_idx]] Example usage ============= Setup ----- .. code-block:: console uart:~$ init uart:~$ bt connect xx:xx:xx:xx:xx:xx public When connected -------------- Discovering sets on a device: .. code-block:: console uart:~$ csip_set_coordinator init <dbg> bt_csip_set_coordinator.primary_discover_func: [ATTRIBUTE] handle 0x0048 <dbg> bt_csip_set_coordinator.primary_discover_func: Discover complete, found 1 instances <dbg> bt_csip_set_coordinator.discover_func: Setup complete for 1 / 1 Found 1 sets on device uart:~$ csip_set_coordinator discover_sets <dbg> bt_csip_set_coordinator.SIRK 36 04 9a dc 66 3a a1 a1 \|6...f:.. 1d 9a 2f 41 01 73 3e 01 \|../A.s>. <dbg> bt_csip_set_coordinator.csip_set_coordinator_discover_sets_read_set_size_cb: 2 <dbg> bt_csip_set_coordinator.csip_set_coordinator_discover_sets_read_set_lock_cb: 1 <dbg> bt_csip_set_coordinator.csip_set_coordinator_discover_sets_read_rank_cb: 1 Set size 2 (pointer: 0x566fdfe8) Discover set members, based on the set pointer above: .. code-block:: console uart:~$ csip_set_coordinator discover_members 0x566fdfe8 <dbg> bt_csip_set_coordinator.csip_found: Found CSIS advertiser with address 34:02:86:03:86:c0 (public) <dbg> bt_csip_set_coordinator.is_set_member: hash: 0x33ccb1, prand 0x5bfe6a <dbg> bt_csip_set_coordinator.is_discovered: 34:02:86:03:86:c0 (public) <dbg> bt_csip_set_coordinator.is_discovered: 34:13:e8:b3:7f:9e (public) <dbg> bt_csip_set_coordinator.csip_found: Found member (2 / 2) Discovered 2/2 set members Lock set members: .. code-block:: console uart:~$ csip_set_coordinator lock_set <dbg> bt_csip_set_coordinator.bt_csip_set_coordinator_lock_set: Connecting to 34:02:86:03:86:c0 (public) <dbg> bt_csip_set_coordinator.csip_set_coordinator_connected: Connected to 34:02:86:03:86:c0 (public) <dbg> bt_csip_set_coordinator.discover_func: Setup complete for 1 / 1 <dbg> bt_csip_set_coordinator.csip_set_coordinator_lock_set_init_cb: <dbg> bt_csip_set_coordinator.SIRK 36 04 9a dc 66 3a a1 a1 \|6...f:.. 1d 9a 2f 41 01 73 3e 01 \|../A.s>. <dbg> bt_csip_set_coordinator.csip_set_coordinator_discover_sets_read_set_size_cb: 2 <dbg> bt_csip_set_coordinator.csip_set_coordinator_discover_sets_read_set_lock_cb: 1 <dbg> bt_csip_set_coordinator.csip_set_coordinator_discover_sets_read_rank_cb: 2 <dbg> bt_csip_set_coordinator.csip_set_coordinator_write_lowest_rank: Locking member with rank 1 <dbg> bt_csip_set_coordinator.notify_func: Instance 0 lock was locked <dbg> bt_csip_set_coordinator.csip_set_coordinator_write_lowest_rank: Locking member with rank 2 <dbg> bt_csip_set_coordinator.notify_func: Instance 0 lock was locked Set locked Release set members: .. code-block:: console uart:~$ csip_set_coordinator release_set <dbg> bt_csip_set_coordinator.csip_set_coordinator_release_highest_rank: Releasing member with rank 2 <dbg> bt_csip_set_coordinator.notify_func: Instance 0 lock was released <dbg> bt_csip_set_coordinator.csip_set_coordinator_release_highest_rank: Releasing member with rank 1 <dbg> bt_csip_set_coordinator.notify_func: Instance 0 lock was released Set released Coordinated Set Member (Server) ******************************************** The server on devices that are part of a set, consisting of at least two devices, e.g. a pair of earbuds.

Most API functions are prefixed by the specification acronym (e.g. `bt_bap` for the Basic Audio Profile (BAP) and `bt_vcp` for the Volume Control Profile (VCP)). The functions are then further prefixed with the specific role from each profile where applicable (e.g. :c:func:`bt_bap_unicast_client_discover` and :c:func:`bt_vcp_vol_rend_set_vol`). There are usually a function per procedure defined by the profile or service specifications, and additional helper or meta functions that do not correspond to procedures. The structure of the files generally also follow this, where BAP related files are prefixed with `bap` and VCP related files are prefixed with `vcp`. If the file is specific for a profile role, the role is also embedded in the file name. Generic Audio Framework (GAF) *************************** The Generic Audio Framework (GAF) is considered the middleware of the Bluetooth LE Audio architecture. The GAF contains the profiles and services that allows higher layer applications and profiles to set up streams, change volume, control media and telephony and more. The GAF builds on GATT, GAP and isochronous channels (ISO). GAF uses GAP to connect, advertise and synchronize to other devices. GAF uses GATT to configure streams, associate streams with content (e.g. media or telephony), control volume and more. GAF uses ISO for the audio streams themselves, both as unicast (connected) audio streams or broadcast (unconnected) audio streams. GAF mandates the use of the LC3 codec, but also supports other codecs. .. graphviz:: :caption: Generic Audio Framework (GAF) digraph gaf { node [shape=record]; edge [style=invis]; compound=true; nodesep=0.1; subgraph hap_layer { cluster=true; label="HAP"; HAS; BAS [style=dashed]; IAS [style=dashed]; } subgraph pbp_layer { cluster=true; label="PBP"; PBS[style=invis]; // Make it possible to treat PBP like the others } subgraph tmap_layer { cluster=true; label="TMAP"; TMAS; } subgraph gmap_layer { cluster=true; label="GMAP"; GMAS; } subgraph gaf_layer { cluster=true; label="Generic Audio Framework"; subgraph transition_and_coordination_control_layer { cluster=true; label="Transition and Coordination Control"; style=dashed; subgraph cap_layer { cluster=true; style=solid; label="CAP"; CAS; } subgraph csip_layer { cluster=true; style=solid; label="CSIP"; CSIS; } } subgraph stream_control_layer { cluster=true; label="Stream Control"; style=dashed; subgraph bap_layer { cluster=true; label="BAP"; style=solid; PACS [style=dashed]; ASCS [style=dashed]; BASS [style=dashed]; } } subgraph content_control_layer { cluster=true; label="Content Control"; style=dashed; subgraph mcp_layer { cluster=true; label="MCP"; style=solid; MCS; } subgraph ccp_layer { cluster=true; label="CCP"; style=solid; TBS; } } subgraph rendering_and_capture_control_layer { cluster=true; label="Rendering and Capture Control"; style=dashed; subgraph micp_layer { cluster=true; label="MICP"; style=solid; MICS; MICP_AICS [style=dashed]; } subgraph vcp_layer { cluster=true; label="VCP"; style=solid; VCS; VOCS [style=dashed]; VCP_AICS [style=dashed]; } } } HAS -> CAS; PBS -> CAS; TMAS -> CAS; GMAS -> CAS; CAS -> MCS; CAS -> TBS; CAS -> ASCS; CAS -> PACS; CAS -> BASS; CAS -> MICS; CAS -> MICP_AICS; CAS -> VCS; CAS -> VOCS; CAS -> VCP_AICS; CSIS -> MCS; CSIS -> TBS; CSIS -> ASCS; CSIS -> PACS; CSIS -> BASS; CSIS -> MICS; CSIS -> MICP_AICS; CSIS -> VCS; CSIS -> VOCS; CSIS -> VCP_AICS; } The top-level profiles TMAP and HAP are not part of the GAF, but rather provide top-level requirements for how to use the GAF.

In these tables 'Server' refers to acting in the GATT server role, and 'Client' refers to acting in the GATT client role for the specific service. If a profile role depends on another profile that depends on a service, then that dependency is implicitly also applied to that profile. For example, if the CAP Acceptor uses the BAP Unicast Server role, then the requirements on the ASCS Server and PACS Server also apply to the CAP Acceptor. The dependencies for Stream Control (BAP) are in the following table. .. table:: BAP dependencies :widths: auto :align: center

+--------+-------------------------------+---------+------------------+-----------------------+--------------------------------------------------+ Using the Bluetooth Audio Stack =============================== To use any of the profiles in the Bluetooth Audio Stack, including the top-level profiles outside of GAF, :kconfig:option:`CONFIG_BT_AUDIO` shall be enabled. This Kconfig option allows the enabling of the individual profiles inside of the Bluetooth Audio Stack. Each profile can generally be enabled on its own, but enabling higher-layer profiles (such as CAP, TMAP and HAP) will typically require enabling some of the lower layer profiles. It is, however, possible to create a device that uses e.g. only Stream Control (with just the BAP), without using any of the content control or rendering/capture control profiles, or vice versa. Using the higher layer profiles will however typically provide a better user experience and better interoperability with other devices. Common Audio Profile (CAP) -------------------------- The Common Audio Profile introduces restrictions and requirements on the lower layer profiles. The procedures in CAP works on one or more streams for one or more devices. Is it thus possible via CAP to do a single function call to setup multiple streams across multiple devices. The figure below shows a complete structure of the procedures in CAP and how they correspond to procedures from the other profiles. The circles with I, A and C show whether the procedure has active involvement or requirements from the CAP Initiator, CAP Accept and CAP Commander roles respectively. .. figure:: img/cap_proc.svg :align: center :alt: Common Audio Profile Procedures Common Audio Profile Procedures The API reference for CAP can be found in :ref:`Common Audio Profile <bluetooth_cap>`. Stream Control (BAP) -------------------- Stream control is implemented by the Basic Audio Profile. This profile defines multiple roles: * Unicast Client * Unicast Server * Broadcast Source * Broadcast Sink * Scan Delegator * Broadcast Assistant Each role can be enabled individually, and it is possible to support more than one role. Notes about the stream control services ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ There are 3 services primarily used by stream control using the Basic Audio Profile. Audio Stream Control Service (ASCS) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ASCS is a service used exclusively for setting up unicast streams, and is located on the BAP Unicast Server device. The service exposes one or more endpoints that can either be a sink or source endpoint, from the perspective of the Unicast Server. That means a sink endpoint is always audio from the Unicast Client to the Unicast Server, and a source endpoint is always from the Unicast Server to the Unicast Client. Unlike most other GATT services, ASCS require that each characteristic in the service has unique data per client. This means that if a Unicast Server is connected to multiple Unicast Clients, the Unicast Clients are not able to see or control the endpoints configured by the other clients. For example if a person's smartphone is streaming audio to a headset, then the same person will not be able to see or control that stream from their smartwatch. Broadcast Audio Scan Service (BASS) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ BASS is a service that is exclusively used by the Scan Delegator and Broadcast Assistant. The main purpose of the service is to offload scanning from low power peripherals to e.g. phones and PCs. Unlike ASCS where the data is required to be unique per client, the data in BASS (called receive states) are (usually) shared among all connected clients. That means it is possible for a person to tell their headphones to synchronize to a Broadcast Source using their phone, and then later tell their headphones to stop synchronizing using their smartwatch. A Broadcast Assistant can be any device, and may only support this one role without any audio capabilities. This allows legacy devices that do not support periodic advertisements or isochronous channels to still provide an interface and scan offloading for peripherals. The Bluetooth SIG have provided a guide on how to develop such legacy Broadcast Assistants that can be found at path_to_url An important note about this guide is that many operating systems (especially on phones), do not allow generic usage of the BASS UUID, effectively making it impossible to implement your own Broadcast Assistant, because you cannot access the BASS. Published Audio Capabilities Service (PACS) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ PACS is used to expose a device's audio capabilities in Published Audio Capabilities (PAC) records. PACS is used by nearly all roles, where the Unicast Client and Broadcast Assistant will act as PACS clients, and Unicast Server and Broadcast Sink will act as PACS servers. These records contain information about the codec, and which values are supported by each codec. The values for the LC3 codec are defined by the Bluetooth Assigned numbers (path_to_url and the values for other codecs such as SBC are left undefined/implementation specific for BAP. PACS also usually share the same data between each connected client, but by using functions such as :c:func:`bt_pacs_conn_set_available_contexts_for_conn`, it is possible to set specific values for specific clients. The API reference for stream control can be found in :ref:`Bluetooth Audio <bluetooth_audio>`. Rendering and Capture Control ----------------------------- Rendering and capture control is implemented by the Volume Control Profile (VCP) and Microphone Control Profile (MICP). The VCP implementation supports the following roles * Volume Control Service (VCS) Server * Volume Control Service (VCS) Client The MICP implementation supports the following roles * Microphone Control Profile (MICP) Microphone Device (server) * Microphone Control Profile (MICP) Microphone Controller (client) The API reference for volume control can be found in :ref:`Bluetooth Volume Control <bluetooth_volume>`. The API reference for Microphone Control can be found in :ref:`Bluetooth Microphone Control <bluetooth_microphone>`. Content Control --------------- Content control is implemented by the Call Control Profile (CCP) and Media Control Profile (MCP). The CCP implementation is not yet implemented in Zephyr. The MCP implementation supports the following roles * Media Control Service (MCS) Server via the Media Proxy module * Media Control Client (MCC) The API reference for media control can be found in :ref:`Bluetooth Media Control <bluetooth_media>`. Generic TBS and Generic MCS ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Both the Telephone Bearer Service (TBS) used by CCP and the Media Control Service (MCS) used by MCP have the concept of generic instances of the services called Generic TBS (GTBS) and Generic MCS (GMCS). While these share a common name prefix, the behavior of these two may be significantly different. Generic TBS ^^^^^^^^^^^ The TBS spec defines GTBS as GTBS provides a single point of access and exposes a representation of its internal telephone bearers into a single telephone bearer. This service provides telephone status and control of the device as a single unit with a single set of characteristics. It is left up to the implementation to determine what telephone bearer a characteristic of GTBS represents at any time. There is no specified manner of representing a characteristic from each individual TBS that resides on the device to the same characteristic of the GTBS. For example, if there is more than one TBS on a device and each has a unique telephone bearer name (e.g., Name1 and Name2), the way the GTBS represents the telephone bearer name is left up to the implementation. GTBS is suited for clients that do not need to access or control all the information available on specific telephone bearers. This means that a GTBS instance represents one or more telephone bearers. A telephone bearer could be any application on a device that can handle (telephone) calls, such as the default Call application on a smartphone, but also other applications such as Signal, Discord, Teams, Slack, etc. GTBS may be standalone (i.e.the device only has a GTBS instance without any TBS instances), and the behavior of the GTBS is mostly left up to the implementation. In Zephyr the implementation of GBTS is that it contains some generic information, such as the provider name which is defined to simply be "Generic TBS", but the majority of the information in the GTBS instance in Zephyr has been implemented to be a union of the data of the other bearers. For example if you have a bearer for regular phone calls and Teams and have an active call in both bearers, then each of those bearers will report a single call, but the GTBS instance will report 2 calls, making it possible for a simple Call Control Client to control all calls from a single bearer. Similarly the supported URIs for each bearer are also made into a union in GTBS, and when placing a call using the GTBS the server will pick the most suited bearer depending on the URI. For example calls with URI `tel` would go to the regular phone application, and calls with the URI `skype` would go to the Teams application. In conclusion the GTBS implementation in Zephyr is a union of the non-generic telephone bearers. Generic MCS ^^^^^^^^^^^ The MCS spec defines GMCS as The GMCS provides status and control of media playback for the device as a single unit. An MCS instance describes and controls the media playback for a specific media player within the device. A device implements MCS instances to allow clients to access the separate internal media player entities. and where the behavior of GMCS is defined as ... the behavior of MCS and GMCS is identical, and all the characteristics and the characteristics' behaviors are the same. The term MCS is used throughout the document. Unless otherwise specifically stated in this specification, the same meaning applies to GMCS as well. This means that a GMCS instance works the same way as an MCS instance, and it follows that GMCS controls the media playback for a specific media player within the device A media player on a device could be anything that plays media, such as a Spotify or Youtube application on a smartphone. Thus if a device has multiple MCS instances, then each of these control media for that specific application, but the GMCS also controls media playback for a specific media player. GMCS can thus be considered a pointer to a specific MCS instance, and control either e.g. Spotify or Youtube, but not both. The MCS spec does however provide an example of GMCS where a device can Implement a GMCS that provides status and control of media playback for the device as a whole. Which may indicate that an implementation may use GMCS to represent all media players with GMCS and not a specific media player as stated above. In the case where a device does not have any MCS instances and only GMCS, then GMCS will point to a generic instance. The Zephyr implementation of MCS and GMCS is incomplete, and currently only supports instantiating a single instance that can either be an MCS or GMCS. This means that the implementation is neither complete nor spec-compliant. Difference between GTBS and GMCS ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The definitions and implementations of GTBS and GMCS as stated above are notably different. GTBS works as a union between the other TBS instances (if any), and GMCS works as a pointer to a specific MCS instance (if any). This effectively means that a simple Call Control Client can control all calls just using GTBS, but a Media Control Client may only be able to control a single player using GMCS. Coordinated Sets ---------------- Coordinated Sets is implemented by the Coordinated Sets Identification Profile (CSIP). The CSIP implementation supports the following roles * Coordinated Set Identification Service (CSIP) Set Member * Coordinated Set Identification Service (CSIP) Set Coordinator The API reference for media control can be found in :ref:`Bluetooth Coordinated Sets <bluetooth_coordinated_sets>`. Specification correctness and data location ------------------------------------------- The implementations are designed to ensure specification compliance as much as possible. When a specification introduces a requirement with e.g. a shall then the implementation should attempt to ensure that this requirement is always followed. Depending on the context of this, the implementation ensures this by rejecting invalid parameters from the application, or from the remote devices. Some requirements from the specifications are not or can not be handled by the stack itself for various reasons. One reason when the stack cannot handle a requirement is if the data related to the requirement is exclusively controlled by the application. An example of this is the advertising data, where multiple service have requirements for what to advertise and when, but where both the advertising state and data is exclusively controlled by the application. Oppositely there are also requirements from the specification, where the data related to the requirement is exclusively controlled by the stack. An example of this is the Volume Control Service (VCS) state, where the specifications mandata that the VCP Volume Renderer (VCS server) modify the values without a choice, e.g. when setting the absolutely volume. In cases like this the application is only notified about the change with a callback, but cannot reject the request (the stack will reject any invalid requests). Generally when the data is simple (like the VCS state which only take up a few bytes), the data is kept in and controlled by the stack, as this can ensure that the requirements can be handled by the stack, making it easier to use a profile role correctly. When the data is more complex (e.g. the PAC records), the data may be kept by the application and the stack only contains a reference to it. When the data is very application specific (e.g. advertising data), the data is kept in and controlled by the application. As a rule of thumb, the return types of the callbacks for each profile implementation indicate whether the data is controlled by the stack or the application. For example all the callbacks for the VCP Volume Renderer have the return type of `void`, but the return type of the BAP Unicast Server callbacks are `int`, indicating that the application not only controls a lot of the Unicast Server data, but can also reject the requests. The choice of what the return type of the callbacks often depend on the specifications, and how much control the role has in a given context. Things worth knowing or considering when using LE Audio ======================================================= This section describes a few tings to consider when contributing to or using LE Audio in Zephyr. The things described by this section are not unique to Zephyr as they are defined by the specifications. Security requirements --------------------- All LE Audio services require Security Level 2 but where the key must be 128-bit and derived via an OOB method or via LE Secure connections. There is no Core-spec defined way of reporting this in GATT, as ATT does not have a specific error code for missing OOB method or LE Secure Connections (although there is a way to report wrong key size). In Zephyr we do not force the device to always use these, as a device that uses LE Audio may also use other profiles and services that do not require such security. We guard all access to services using a custom security check implemented in :zephyr_file:`subsys/bluetooth/audio/audio.c`, where all LE Audio services must use the internal `BT_AUDIO_CHRC` macro for proper security verification. Access to the LTK for encrypted SIRKs in CSIS --------------------------------------------- The Coordinated Set Identification Service (CSIS) may encrypt the SIRK (set identity resolving key). The process of encrypting the SIRK requires the LTK as the encryption key, which is typically not exposed to higher layer implementations such as CSIS. This does not have any effect on the security though. MTU requirements ---------------- The Basic Audio Profile (BAP) has a requirement that both sides shall support a minimum ATT_MTU of at least 64 on the unenhanced ATT bearer or at least one enhanced ATT bearer. The requirement comes from the preferred (or sometimes mandatory) use of GATT Write Without Response, and where support for Write Long Characteristic Value is optional in most cases. If a ASCS device supports values larger than the minimum ATT_MTU of 64 octets, then it shall support Read long Characteristic Value by setting :kconfig:option:`CONFIG_BT_ATT_PREPARE_COUNT` to a non-zero value. LE Audio resources ################## This section contains some links and reference to resources that are useful for either contributors to the LE Audio Stack in Zephyr, LE Audio application developers or both. The LE audio channel on Discord ***************************** Zephyr has a specific Discord channel for LE Audio development, which is open to all. Find it here at path_to_url or simply search for `ble-audio` from within Discord. Since the `ble-audio` channel is open for all, we cannot discuss any specifications that are in development in that channel. For discussions that require a Bluetooth SIG membership we refer to the `bluetooth-sig` Discord channel found at path_to_url Zephyr weekly meetings ****************** Anyone who is a Bluetooth SIG member and a Zephyr member can join the weekly meetings where we discuss and plan the development of LE Audio in Zephyr. You can find the time of the meetings by joining the Bluetooth-sig group at path_to_url Github project ********** LE Audio in Zephyr has its own Github project available at path_to_url The project is mostly automated, and the LE Audio contributors almost only rely on the automated workflows to present the state of development. Anyone is able to pick any of the open issues and work on it. If you cannot assign the issue to yourself, please leave a comment in the issue itself or ping the Discord channel for help. Bluetooth SIG errata for LE Audio ******************************* There are many specifications for LE Audio, and several of them are still being updated and developed. To get an overview of the errata for the LE Audio specifications you can visit * Generic Audio (GA) errata path_to_url * Hearing Aid (HA) errata path_to_url * Audio, Telephony and Automotive (ATA) errata path_to_url Access to errata requires a Bluetooth SIG membership. Bluetooth SIG working groups for LE Audio ***************************************** There are 3 working groups in the Bluetooth SIG related to LE Audio: * Generic Audio (GA) path_to_url * Hearing Aid (HA) path_to_url * Audio, Telephony, and Automotive (ATA) path_to_url By joining these groups you will also get emails from their respective mailing lists, where multiple questions and discussions are handled. The working groups also have scheduled weekly meetings, where issues and the development of the specifications are handled. Access to the Bluetooth SIG working groups requires a Bluetooth SIG membership. The LE Audio Book *************** There is a free ebook on LE Audio at path_to_url The book was released in January 2022, and thus before some of the specifications were finalized, but also before some of the released updates to the specifications. Nevertheless the book still provides a good explanation for many of the concepts and ideas, but please refer to the individual specifications for technical information. Bluetooth SIG informational papers, reports and guides **************************************************** The Bluetooth SIG occasionally release new informational papers, report and guides. These can be found at path_to_url Here you will also find the aforementioned LE Audio book, among many other good resources. ```	/content/code_sandbox/doc/connectivity/bluetooth/api/audio/bluetooth-le-audio-arch.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	13,551
```restructuredtext Bluetooth: Common Audio Profile Shell ##################################### This document describes how to run the Common Audio Profile functionality. CAP Acceptor ********** The Acceptor will typically be a resource-constrained device, such as a headset, earbud or hearing aid. The Acceptor can initialize a Coordinated Set Identification Service instance, if it is in a pair with one or more other CAP Acceptors. Using the CAP Acceptor ====================== When the Bluetooth stack has been initialized (:code:`bt init`), the Acceptor can be registered by calling :code:`cap_acceptor init`, which will register the CAS and CSIS services, as well as register callbacks. .. code-block:: console cap_acceptor --help cap_acceptor - Bluetooth CAP acceptor shell commands Subcommands: init :Initialize the service and register callbacks [size <int>] [rank <int>] [not-lockable] [sirk <data>] lock :Lock the set release :Release the set [force] sirk :Set the currently used SIRK <sirk> get_sirk :Get the currently used SIRK sirk_rsp :Set the response used in SIRK requests <accept, accept_enc, reject, oob> Besides initializing the CAS and the CSIS, there are also commands to lock and release the CSIS instance, as well as printing and modifying access to the SIRK of the CSIS. Setting a new SIRK ------------------ This command can modify the currently used SIRK. To get the new RSI to advertise on air, :code:`bt adv-data` or :code:`bt advertise` must be called again to set the new advertising data. If :code:`CONFIG_BT_CSIP_SET_MEMBER_NOTIFIABLE` is enabled, this will also notify connected clients. .. code-block:: console uart:~$ cap_acceptor sirk 00112233445566778899aabbccddeeff SIRK updated Getting the current SIRK ------------------------ This command can get the currently used SIRK. .. code-block:: console uart:~$ cap_acceptor get_sirk SIRK 36 04 9a dc 66 3a a1 a1 \|6...f:.. 1d 9a 2f 41 01 73 3e 01 \|../A.s>. CAP Initiator ********* The Initiator will typically be a resource-rich device, such as a phone or PC. The Initiator can discover CAP Acceptors's CAS and optional CSIS services. The CSIS service can be read to provide information about other CAP Acceptors in the same Coordinated Set. The Initiator can execute stream control procedures on sets of devices, either ad-hoc or Coordinated, and thus provides an easy way to setup multiple streams on multiple devices at once. Using the CAP Initiator ======================= When the Bluetooth stack has been initialized (:code:`bt init`), the Initiator can discover CAS and the optionally included CSIS instance by calling (:code:`cap_initiator discover`). The CAP initiator also supports broadcast audio as a source. .. code-block:: console uart:~$ cap_initiator --help cap_initiator - Bluetooth CAP initiator shell commands Subcommands: discover : Discover CAS unicast_start : Unicast Start [csip] [sinks <cnt> (default 1)] [sources <cnt> (default 1)] [conns (<cnt> \| all) (default 1)] unicast_list : Unicast list streams unicast_update : Unicast Update <all \| stream [stream [stream...]]> unicast_stop : Unicast stop streams [stream [stream [stream...]]] (all by default) unicast_cancel : Unicast cancel current procedure ac_1 : Unicast audio configuration 1 ac_2 : Unicast audio configuration 2 ac_3 : Unicast audio configuration 3 ac_4 : Unicast audio configuration 4 ac_5 : Unicast audio configuration 5 ac_6_i : Unicast audio configuration 6(i) ac_6_ii : Unicast audio configuration 6(ii) ac_7_i : Unicast audio configuration 7(i) ac_7_ii : Unicast audio configuration 7(ii) ac_8_i : Unicast audio configuration 8(i) ac_8_ii : Unicast audio configuration 8(ii) ac_9_i : Unicast audio configuration 9(i) ac_9_ii : Unicast audio configuration 9(ii) ac_10 : Unicast audio configuration 10 ac_11_i : Unicast audio configuration 11(i) ac_11_ii : Unicast audio configuration 11(ii) broadcast_start : broadcast_update : <meta> broadcast_stop : broadcast_delete : ac_12 : Broadcast audio configuration 12 ac_13 : Broadcast audio configuration 13 ac_14 : Broadcast audio configuration 14 Before being able to perform any stream operation, the device must also perform the :code:`bap discover` operation to discover the ASEs and PAC records. The :code:`bap init` command also needs to be called. When connected -------------- Discovering CAS and CSIS on a device: .. code-block:: console uart:~$ cap_initiator discover discovery completed with CSIS Discovering ASEs and PAC records on a device: .. code-block:: console uart:~$ bap discover conn 0x81cc260: #0: codec 0x81d5b28 dir 0x01 codec 0x06 cid 0x0000 vid 0x0000 count 5 data #0: type 0x01 len 2 00000000: f5 \|. \| data #1: type 0x02 len 1 data #2: type 0x03 len 1 data #3: type 0x04 len 4 00000000: 1e 00 f0 \|... \| data #4: type 0x05 len 1 meta #0: type 0x01 len 2 00000000: 06 \|. \| dir 1 loc 1 snk ctx 6 src ctx 6 Conn: 0x81cc260, Sink #0: ep 0x81e4248 Conn: 0x81cc260, Sink #1: ep 0x81e46a8 conn 0x81cc260: #0: codec 0x81d5f00 dir 0x02 codec 0x06 cid 0x0000 vid 0x0000 count 5 data #0: type 0x01 len 2 00000000: f5 \|. \| data #1: type 0x02 len 1 data #2: type 0x03 len 1 data #3: type 0x04 len 4 00000000: 1e 00 f0 \|... \| data #4: type 0x05 len 1 meta #0: type 0x01 len 2 00000000: 06 \|. \| dir 2 loc 1 snk ctx 6 src ctx 6 Conn: 0x81cc260, Source #0: ep 0x81e5c88 Conn: 0x81cc260, Source #1: ep 0x81e60e8 Discover complete: err 0 Both of the above commands should be done for each device that you want to use in the set. To use multiple devices, simply connect to more and then use :code:`bt select` the device to execute the commands on. Once all devices have been connected and the respective discovery commands have been called, the :code:`cap_initiator unicast_start` command can be used to put one or more streams into the streaming state. .. code-block:: console uart:~$ cap_initiator unicast_start sinks 1 sources 0 conns all Setting up 1 sinks and 0 sources on each (2) conn Starting 1 streams Unicast start completed To stop all the streams that has been started, the :code:`cap_initiator unicast_stop` command can be used. .. code-block:: console uart:~$ cap_initiator unicast_stop all Unicast stop completed When doing broadcast -------------------- To start a broadcast as the CAP initiator there are a few steps to be done: 1. Create and configure an extended advertising set with periodic advertising 2. Create and configure a broadcast source 3. Setup extended and periodic advertising data The following commands will setup a CAP broadcast source using the 16_2_1 preset (defined by BAP): .. code-block:: console bt init bap init bt adv-create nconn-nscan ext-adv name bt per-adv-param bap preset broadcast 16_2_1 cap_initiator ac_12 bt adv-data discov bt per-adv-data cap_initiator broadcast_start The broadcast source is created by the :code:`cap_initiator ac_12`, :code:`cap_initiator ac_13`, and :code:`cap_initiator ac_14` commands, configuring the broadcast source for the defined audio configurations from BAP. The broadcast source can then be stopped with :code:`cap_initiator broadcast_stop` or deleted with :code:`cap_initiator broadcast_delete`. The metadata of the broadcast source can be updated at any time, including when it is already streaming. To update the metadata the :code:`cap_initiator broadcast_update` command can be used. The command takes an array of data, and the only requirement (besides having valid data) is that the streaming context shall be set. For example to set the streaming context to media, the command can be used as .. code-block:: console cap_initiator broadcast_update 03020400 CAP Broadcast source updated with new metadata. Update the advertised base via `bt per-adv-data` bt per-adv-data The :code:`bt per-adv-data` command should be used afterwards to update the data is the advertised BASE. The data must be little-endian, so in the above example the metadata :code:`03020400` is setting the metadata entry with :code:`03` as the length, :code:`02` as the type (streaming context) and :code:`0400` as the value :code:`BT_AUDIO_CONTEXT_TYPE_MEDIA` (which has the numeric value of 0x). CAP Commander *********** The Commander will typically be a either co-located with a CAP Initiator or be on a separate resource-rich mobile device, such as a phone or smartwatch. The Commander can discover CAP Acceptors's CAS and optional CSIS services. The CSIS service can be read to provide information about other CAP Acceptors in the same Coordinated Set. The Commander can provide information about broadcast sources to CAP Acceptors or coordinate capture and rendering information such as mute or volume states. Using the CAP Commander ======================= When the Bluetooth stack has been initialized (:code:`bt init`), the Commander can discover CAS and the optionally included CSIS instance by calling (:code:`cap_commander discover`). .. code-block:: console cap_commander --help cap_commander - Bluetooth CAP commander shell commands Subcommands: discover :Discover CAS cancel :CAP commander cancel current procedure change_volume :Change volume on all connections <volume> change_volume_mute :Change volume mute state on all connections <mute> change_volume_offset :Change volume offset per connection <volume_offset [volume_offset [...]]> change_microphone_mute :Change microphone mute state on all connections <mute> change_microphone_gain :Change microphone gain per connection <gain [gain [...]]> Before being able to perform any stream operation, the device must also perform the :code:`bap discover` operation to discover the ASEs and PAC records. The :code:`bap init` command also needs to be called.

```restructuredtext .. _introducing_zephyr: Introduction ############ The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained and embedded systems: from simple embedded environmental sensors and LED wearables to sophisticated embedded controllers, smart watches, and IoT wireless applications. The Zephyr kernel supports multiple architectures, including: - ARCv2 (EM and HS) and ARCv3 (HS6X) - ARMv6-M, ARMv7-M, and ARMv8-M (Cortex-M) - ARMv7-A and ARMv8-A (Cortex-A, 32- and 64-bit) - ARMv7-R, ARMv8-R (Cortex-R, 32- and 64-bit) - Intel x86 (32- and 64-bit) - MIPS (MIPS32 Release 1 specification) - NIOS II Gen 2 - RISC-V (32- and 64-bit) - SPARC V8 - Tensilica Xtensa The full list of supported boards based on these architectures can be found :ref:`here <boards>`. In the context of the Zephyr OS, a :term:`subsystem` refers to a logically distinct part of the operating system that handles specific functionality or provides certain services. Subsystems can include components such as networking, file systems, device driver classes, power management, and communication protocols, among others. Each subsystem is designed to be modular and can be configured, customized, and extended to meet the requirements of different embedded applications. Licensing ******* Zephyr is permissively licensed using the `Apache 2.0 license`_ (as found in the ``LICENSE`` file in the project's `GitHub repo`_). There are some imported or reused components of the Zephyr project that use other licensing, as described in :ref:`Zephyr_Licensing`. .. _Apache 2.0 license: path_to_url .. _GitHub repo: path_to_url Distinguishing Features ******************* Zephyr offers a large and ever growing number of features including: Extensive suite of Kernel services** Zephyr offers a number of familiar services for development: * Multi-threading Services for cooperative, priority-based, non-preemptive, and preemptive threads with optional round robin time-slicing. Includes POSIX pthreads compatible API support. * Interrupt Services for compile-time registration of interrupt handlers. * Memory Allocation Services for dynamic allocation and freeing of fixed-size or variable-size memory blocks. * Inter-thread Synchronization Services for binary semaphores, counting semaphores, and mutex semaphores. * Inter-thread Data Passing Services for basic message queues, enhanced message queues, and byte streams. * Power Management Services such as overarching, application or policy-defined, System Power Management and fine-grained, driver-defined, Device Power Management. Multiple Scheduling Algorithms Zephyr provides a comprehensive set of thread scheduling choices: * Cooperative and Preemptive Scheduling * Earliest Deadline First (EDF) * Meta IRQ scheduling implementing "interrupt bottom half" or "tasklet" behavior * Timeslicing: Enables time slicing between preemptible threads of equal priority * Multiple queuing strategies: * Simple linked-list ready queue * Red/black tree ready queue * Traditional multi-queue ready queue .. _zephyr_intro_configurability: Highly configurable / Modular for flexibility Allows an application to incorporate only the capabilities it needs as it needs them, and to specify their quantity and size. Cross Architecture Supports a wide variety of :ref:`supported boards<boards>` with different CPU architectures and developer tools. Contributions have added support for an increasing number of SoCs, platforms, and drivers. Memory Protection Implements configurable architecture-specific stack-overflow protection, kernel object and device driver permission tracking, and thread isolation with thread-level memory protection on x86, ARC, and ARM architectures, userspace, and memory domains. For platforms without MMU/MPU and memory constrained devices, supports combining application-specific code with a custom kernel to create a monolithic image that gets loaded and executed on a system's hardware. Both the application code and kernel code execute in a single shared address space. Compile-time resource definition Allows system resources to be defined at compile-time, which reduces code size and increases performance for resource-limited systems. Optimized Device Driver Model Provides a consistent device model for configuring the drivers that are part of the platform/system and a consistent model for initializing all the drivers configured into the system and allows the reuse of drivers across platforms that have common devices/IP blocks. Devicetree Support Use of :ref:`devicetree <dt-guide>` to describe hardware. Information from devicetree is used to create the application image. Native Networking Stack supporting multiple protocols Networking support is fully featured and optimized, including LwM2M and BSD sockets compatible support. OpenThread support (on Nordic chipsets) is also provided - a mesh network designed to securely and reliably connect hundreds of products around the home. Bluetooth Low Energy 5.0 support Bluetooth 5.0 compliant (ESR10) and Bluetooth Low Energy Controller support (LE Link Layer). Includes Bluetooth Mesh and a Bluetooth qualification-ready Bluetooth controller. * Generic Access Profile (GAP) with all possible LE roles * Generic Attribute Profile (GATT) * Pairing support, including the Secure Connections feature from Bluetooth 4.2 * Clean HCI driver abstraction * Raw HCI interface to run Zephyr as a Controller instead of a full Host stack * Verified with multiple popular controllers * Highly configurable Mesh Support: * Relay, Friend Node, Low-Power Node (LPN) and GATT Proxy features * Both Provisioning bearers supported (PB-ADV & PB-GATT) * Highly configurable, fitting in devices with at least 16k RAM Native Linux, macOS, and Windows Development A command-line CMake build environment runs on popular developer OS systems. A native port (:ref:`native_sim <native_sim>`) lets you build and run Zephyr as a native application on Linux, aiding development and testing. Virtual File System Interface with ext2, FatFs, and LittleFS Support ext2, LittleFS and FatFS support; FCB (Flash Circular Buffer) for memory constrained applications. Powerful multi-backend logging Framework Support for log filtering, object dumping, panic mode, multiple backends (memory, networking, filesystem, console, ...) and integration with the shell subsystem. User friendly and full-featured Shell interface A multi-instance shell subsystem with user-friendly features such as autocompletion, wildcards, coloring, metakeys (arrows, backspace, ctrl+u, etc.) and history. Support for static commands and dynamic sub-commands. Settings on non-volatile storage The settings subsystem gives modules a way to store persistent per-device configuration and runtime state. Settings items are stored as key-value pair strings. Non-volatile storage (NVS) NVS allows storage of binary blobs, strings, integers, longs, and any combination of these. Native port :ref:`Native sim <native_sim>` allows running Zephyr as a Linux application with support for various subsystems and networking. .. include:: ../../README.rst :start-after: start_include_here Fundamental Terms and Concepts ****************************** See :ref:`glossary` ```	/content/code_sandbox/doc/introduction/index.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	1,691

```python # """ A Sphinx extension for documenting devicetree content. It adds a role and a directive with the same name, 'dtcompatible'. :dtcompatible:`vnd,foo` This role can be used inline to make a reference to the generated documentation for a devicetree compatible given as argument. For example, :dtcompatible:`vnd,foo` would create a reference to the generated documentation page for the devicetree binding handling compatible "vnd,foo". There may be more than one page for a single compatible. For example, that happens if a binding behaves differently depending on the bus the node is on. If that occurs, the reference points at a "disambiguation" page which links out to all the possibilities, similarly to how Wikipedia disambiguation pages work. The Zephyr documentation uses the standard :option: role to refer to Kconfig options. The :dtcompatible: option is like that, except using its own role to avoid using one that already has a standard meaning. (The :option: role is meant for documenting options to command-line programs, not Kconfig symbols.) .. dtcompatible:: vnd,foo This directive marks the page where the :dtcompatible: role link goes. Do not use it directly. The generated bindings documentation puts these in the right places.

```python """ External content ################ Introduction ============ This extension allows to import sources from directories out of the Sphinx source directory. They are copied to the source directory before starting the build. Note that the copy is smart, that is, only updated files are actually copied. Therefore, incremental builds detect changes correctly and behave as expected. Paths for external content included via e.g. figure, literalinclude, etc. are adjusted as needed. Configuration options ===================== - ``external_content_contents``: A list of external contents. Each entry is a tuple with two fields: the external base directory and a file glob pattern. - ``external_content_directives``: A list of directives that should be analyzed and their paths adjusted if necessary. Defaults to ``DEFAULT_DIRECTIVES``. - ``external_content_keep``: A list of file globs (relative to the destination directory) that should be kept even if they do not exist in the source directory.

It is meant to be used with other plugins such as ``breathe`` in order to improve the user experience. The principal features offered by this plugin are: - Doxygen build is run before Sphinx reads input files - Doxyfile can be optionally pre-processed so that variables can be inserted - Changes in the Doxygen input files are tracked so that Doxygen build is only run if necessary. - Synchronizes Doxygen XML output so that even if Doxygen is run only changed, deleted or added files are modified. References: - path_to_url Configuration options ===================== - ``doxyrunner_doxygen``: Path to the Doxygen binary. - ``doxyrunner_doxyfile``: Path to Doxyfile. - ``doxyrunner_outdir``: Doxygen build output directory (inserted to ``OUTPUT_DIRECTORY``) - ``doxyrunner_outdir_var``: Variable representing the Doxygen build output directory, as used by ``OUTPUT_DIRECTORY``. This can be useful if other Doxygen variables reference to the output directory. - ``doxyrunner_fmt``: Flag to indicate if Doxyfile should be formatted. - ``doxyrunner_fmt_vars``: Format variables dictionary (name: value). - ``doxyrunner_fmt_pattern``: Format pattern. - ``doxyrunner_silent``: If Doxygen output should be logged or not.

```python """ Zephyr Extension ################ Introduction ============ This extension adds a new ``zephyr`` domain for handling the documentation of various entities specific to the Zephyr RTOS project (ex. code samples). Directives ---------- - ``zephyr:code-sample::`` - Defines a code sample. The directive takes an ID as the main argument, and accepts ``:name:`` (human-readable short name of the sample) and ``:relevant-api:`` (a space separated list of Doxygen group(s) for APIs the code sample is a good showcase of) as options. The content of the directive is used as the description of the code sample. Example: ``` .. zephyr:code-sample:: blinky :name: Blinky :relevant-api: gpio_interface Blink an LED forever using the GPIO API. ``` Roles ----- - ``:zephyr:code-sample:`` - References a code sample. The role takes the ID of the code sample as the argument. The role renders as a link to the code sample, and the link text is the name of the code sample (or a custom text if an explicit name is provided). Example: ``` Check out :zephyr:code-sample:`sample-foo` for an example of how to use the foo API. You may also be interested in :zephyr:code-sample:`this one <sample-bar>`. ``` """ from typing import Any, Dict, Iterator, List, Tuple from docutils import nodes from docutils.nodes import Node from docutils.parsers.rst import Directive, directives from sphinx import addnodes from sphinx.domains import Domain, ObjType from sphinx.roles import XRefRole from sphinx.transforms import SphinxTransform from sphinx.transforms.post_transforms import SphinxPostTransform from sphinx.util import logging from sphinx.util.nodes import NodeMatcher, make_refnode from zephyr.doxybridge import DoxygenGroupDirective from zephyr.gh_utils import gh_link_get_url import json __version__ = "0.1.0" logger = logging.getLogger(__name__) class CodeSampleNode(nodes.Element): pass class RelatedCodeSamplesNode(nodes.Element): pass class ConvertCodeSampleNode(SphinxTransform): default_priority = 100 def apply(self): matcher = NodeMatcher(CodeSampleNode) for node in self.document.traverse(matcher): self.convert_node(node) def convert_node(self, node): """ Transforms a `CodeSampleNode` into a `nodes.section` named after the code sample name.

This is useful, for example, when adding features like "Open on GitHub" on top of pages, direct links to open a GitHub issue regarding a page, or date of the most recent commit to a page. The extension installs the following Jinja filter: * ``gh_link_get_blob_url``: Returns a URL to the source of a page on GitHub. * ``gh_link_get_edit_url``: Returns a URL to edit the given page on GitHub. * ``gh_link_get_open_issue_url``: Returns a URL to open a new issue regarding the given page. * ``git_info``: Returns the date and SHA1 of the last commit made to a page (if this page is managed by Git). Configuration options ===================== - ``gh_link_version``: GitHub version to use in the URL (e.g. "main") - ``gh_link_base_url``: Base URL used as a prefix for generated URLs. - ``gh_link_prefixes``: Mapping of pages (regex) <> GitHub prefix. - ``gh_link_exclude``: List of pages (regex) that will not report a URL.

```python """ Kconfig Extension ################# Introduction ============ This extension adds a new domain (``kconfig``) for the Kconfig language. Unlike many other domains, the Kconfig options are not rendered by Sphinx directly but on the client side using a database built by the extension. A special directive ``.. kconfig:search::`` can be inserted on any page to render a search box that allows to browse the database. References to Kconfig options can be created by using the ``:kconfig:option:`` role. Kconfig options behave as regular domain objects, so they can also be referenced by other projects using Intersphinx. Options ======= - kconfig_generate_db: Set to True if you want to generate the Kconfig database. This is only required if you want to use the ``.. kconfig:search::`` directive, not if you just need support for Kconfig domain (e.g. when using Intersphinx in another project). Defaults to False. - kconfig_ext_paths: A list of base paths where to search for external modules Kconfig files when they use ``kconfig-ext: True``. The extension will look for ${BASE_PATH}/modules/${MODULE_NAME}/Kconfig.

```restructuredtext .. _bug_reporting: Bug Reporting ############## To maintain traceability and relation between proposals, changes, features, and issues, it is recommended to cross-reference source code commits with the relevant GitHub issues and vice versa. Any changes that originate from a tracked feature or issue should contain a reference to the feature by mentioning the corresponding issue or pull-request identifiers. At any time it should be possible to establish the origin of a change and the reason behind it by following the references in the code. Reporting a regression issue **************************** It could happen that the issue being reported is identified as a regression, as the use case is known to be working on earlier commit or release. In this case, providing directly the guilty commit when submitting the bug gains a lot of time in the eventual bug fixing. To identify the commit causing the regression, several methods could be used, but tree bisecting method is an efficient one that doesn't require deep code expertise and can be used by every one. For this, `git bisect`_ is the recommended tool. Recommendations on the process: * Run ``west update`` on each bisection step. * Once the bisection is over and a culprit identified, verify manually the result. .. _git bisect: path_to_url ```	/content/code_sandbox/doc/project/issues.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	270
```restructuredtext TSC Working Groups **************** Overview ######## The TSC, at its discretion, may establish working groups or subcommittees to serve as focused teams dedicated to specific technical areas, initiatives, or tasks. Membership ########## Working Group Membership Eligibility ++++++++++++++++++++++++++++++++++++ - Each Working group (WG) shall determine its own membership eligibility, in consultation with the TSC. - Each working group shall have a team of members who are actively involved in its activities and decision-making processes. - It is expected that WG membership shall be open to all Zephyr project :ref:`Collaborators <collaborator>`**; however, working groups may impose restrictions such as the number of participants from a single company. - All TSC members are eligible to join a working group as members, part of the responsibilities being a TSC member. - The minimal number of members may vary depending on the complexity of the tasks and the breadth of expertise required to address them effectively. - A working group should aim to have at least five to seven members to ensure diversity of perspectives, collaboration, and continuity. - The structure of each working group within the Zephyr Project should be designed to ensure effectiveness, productivity, and inclusivity. While the optimal size of a working group can vary depending on the specific context and scope of its activities. - Participation in WG meetings and discussions is open to all project :ref:`contributors <contributor>`. Working Group Chair / Co-chair ++++++++++++++++++++++++++++++ Each working group may elect a Chair and optionally a Co-Chair who is responsible for leading meetings and representing the working group to the TSC. Working Group Chair / Co-Chair Elections ++++++++++++++++++++++++++++++++++++++++ - The Chair and Co-Chair shall be elected by the members of the working group - Any member of the working group has the right to nominate themselves for the chair/co-chair positions. - The term for the chair/co-chair is one year - If a chair/co-chair resigns from the position before the end of the term, a vote is to be held to elect a new chair/co-chair.

```restructuredtext .. _feature-tracking: Feature Tracking ################# For feature tracking we use Github labels to classify new features and enhancements. The following is the description of each category: Enhancement Changes to existing features that are not considered a bug and would not block a release. This is an incremental enhancement to a feature that already exists in Zephyr. Feature request A request for the implementation or inclusion of a new unit of functionality that is not part of any release plans yet, that has not been vetted, and needs further discussion and details. Feature A committed and planned unit of functionality with a detailed design and implementation proposal and an owner. Features must go through an RFC process and must be vetted and discussed in the TSC before a target milestone is set. Hardware Support A request or plan to port an existing feature or enhancement to a particular hardware platform. This ranges from porting Zephyr itself to a new architecture, SoC or board to adding an implementation of a peripheral driver API for an existing hardware platform. Meta A label to group other GitHub issues that are part of a single feature or unit of work. The following workflow should be used to process features:. This is the formal way for asking for a new feature in Zephyr and indicating its importance to the project. Often, the requester may have a readiness and willingness to drive implementation of the feature in an upcoming release, and should assign the request to themselves. If not though, an owner will be assigned after evaluation by the TSC. A feature request can also have a companion RFC with more details on the feature and a proposed design or implementation. - Label new features requests as ``feature-request`` - The TSC discusses new ``feature-request`` items regularly and triages them. Items are examined for similarity with existing features, how they fit with the project goals and other timeline considerations. The priority is determined as follows: - High = Next milestone - Medium = As soon as possible - Low = Best effort - After the initial discussion and triaging, the label is moved from ``feature-request`` to ``feature`` with the target milestone and an assignee. All items marked as ``feature-request`` are non-binding and those without an assignee are open for grabs, meaning that they can be picked up and implemented by any project member or the community. You should contact an assigned owner if you'd like to discuss or contribute to that feature's implementation Roadmap and Release Plans ************************* Project roadmaps and release plans are both important tools for the project, but they have very different purposes and should not be confused. A project roadmap communicates the high-level overview of a project's strategy, while a release plan is a tactical document designed to capture and track the features planned for upcoming releases. - The project roadmap communicates the why; a release plan details the what - A release plan spans only a few months; a product roadmap might cover a year or more Project Roadmap ================ The project roadmap should serve as a high-level, visual summary of the project's strategic objectives and expectations. If built properly, the roadmap can be a valuable tool for several reasons. It can help the project present its plan in a compelling way to existing and new stakeholders, to help recruit new members and it can be a helpful resource the team and community can refer to throughout the project's development, to ensure they are still executing according to plan. As such, the roadmap should contain only strategic-level details, major project themes, epics, and goals. Release Plans ============== The release plan comes into play when the project roadmap's high-level strategy is translated into an actionable plan built on specific features, enhancements, and fixes that need to go into a specific release or milestone. The release plan communicates those features and enhancements slated for your project' next release (or the next few releases). So it acts as more of a project plan, breaking the big ideas down into smaller projects the community and main stakeholders of the project can make progress on. Items labeled as ``features`` are short or long term release items that shall have an assignee and a milestone set. ```	/content/code_sandbox/doc/project/proposals.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	905
```restructuredtext .. _code-flow-and-branches: Code Flow and Branches ###################### Introduction ************ The zephyr Git repository has three types of branches: main Which contains the latest state of development collab-\* Collaboration branches that are used for shared development of new features to be introduced into the main branch when ready. Creating a new collaboration branch requires a justification and TSC approval. Collaboration branches shall be based off the main branch and any changes developed in the collab branch shall target the main development branch. For released versions of Zephyr, the introduction of fixes and new features, if approved by the TSC, shall be done using backport pull requests. vx.y-branch Branches which track maintenance releases based on a major release Development in collaboration branches before features go to mainline allows teams to work independently on a subsystem or a feature, improves efficiency and turnaround time, and encourages collaboration and streamlines communication between developers. Changes submitted to a collaboration branch can evolve and improve incrementally in a branch, before they are submitted to the mainline tree for final integration. By dedicating an isolated branch to complex features, it's possible to initiate in-depth discussions around new additions before integrating them into the official project. Collaboration branches are ephemeral and shall be removed once the collaboration work has been completed. When a branch is requested, the proposal should include the following: * Define exit criteria for merging the collaboration branch changes back into the main branch. * Define a timeline for the expected life cycle of the branch. It is recommended to select a Zephyr release to set the timeline. Extensions to this timeline requires TSC approval. Roles and Responsibilities ************************** Collaboration branch owners have the following responsibilities: - Use the infrastructure and tools provided by the project (GitHub, Git) - All changes to collaboration branches shall come in form of github pull requests. - Force pushing a collaboration branch is only allowed when rebasing against the main branch. - Review changes coming from team members and request review from branch owners when submitting changes. - Keep the branch in sync with upstream and update on a regular basis. - Push changes frequently to upstream using the following methods: - GitHub pull requests: for example, when reviews have not been done in the local branch (one-man branch). - Merge requests: When a set of changes has been done in a local branch and has been reviewed and tested in a collaboration branch. ```	/content/code_sandbox/doc/project/code_flow.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	532
```restructuredtext .. _modifying_contributions: Modifying Contributions made by other developers ************************************************ Scenarios ######### Zephyr contributors and collaborators are encouraged to assist as reviewers in pull requests, so that patches may be approved and merged to Zephyr's main branch as part of the original pull requests. The authors of the pull requests are responsible for amending their original commits following the review process. There are occasions, however, when a contributor might need to modify patches included in pull requests that are submitted by other Zephyr contributors. For instance, this is the case when: * a developer cherry-picks commits submitted by other contributors into their own pull requests in order to: * integrate useful content which is part of a stale pull request, or * get content merged to the project's main branch as part of a larger patch * a developer pushes to a branch or pull request opened by another contributor in order to: * assist in updating pull requests in order to get the patches merged to the project's main branch * drive stale pull requests to completion so they can be merged Accepted policies ################# A developer who intends to cherry-pick and potentially modify patches sent by another contributor shall: * clarify in their pull request the reason for cherry-picking the patches, instead of assisting in getting the patches merged in their original pull request, and * invite the original author of the patches to their pull request review. A developer who intends to force-push to a branch or pull request of another Zephyr contributor shall clarify in the pull request the reason for pushing and for modifying the existing patches (e.g. stating that it is done to drive the pull request review to completion, when the pull request author is not able to do so). .. note:: Developers should try to limit the above practice to pull requests identified as stale. Read about how to identify pull requests as stale in :ref:`development processes and tools <dev-environment-and-tools>` If the original patches are substantially modified, the developer can either: * (preferably) reach out to the original author and request them to acknowledge that the modified patches may be merged while having the original sign-off line and author identity, or * submit the modified patches as their own work (i.e. with their own sign-off line and author identity). In this case, the developer shall identify in the commit message(s) the original source the submitted work is based on (mentioning, for example, the original PR number). .. note:: Contributors should uncheck the box Allow Edits By Maintainers" to indicate that they do not wish their patches to be amended, inside their original branch or pull request, by other Zephyr developers. ```	/content/code_sandbox/doc/project/modifying_contributions.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	601
```restructuredtext .. _development_model: Project and Governance ####################### .. toctree:: :maxdepth: 1 tsc project_roles.rst working_groups release_process proposals code_flow modifying_contributions.rst dev_env_and_tools issues communication documentation The Zephyr project defines a development process workflow using GitHub Issues to track feature, enhancement, and bug reports together with GitHub Pull Requests (PRs) for submitting and reviewing changes. Zephyr community members work together to review these Issues and PRs, managing feature enhancements and quality improvements of Zephyr through its regular releases, as outlined in the `program management overview <path_to_url`_. We can only manage the volume of Issues and PRs, by requiring timely reviews, feedback, and responses from the community and contributors, both for initial submissions and for followup questions and clarifications. Read about the project's :ref:`development processes and tools <dev-environment-and-tools>` and specifics about :ref:`review timelines <review_time>` to learn about the project's goals and guidelines for our active developer community. :ref:`project_roles` describes in detail the Zephyr project roles and associated permissions with respect to the development process workflow. Terminology *********** - mainline: The main tree where the core functionality and core features are being developed. - subsystem/feature branch: is a branch within the same repository. In our case, we will use the term branch also when referencing branches not in the same repository, which are a copy of a repository sharing the same history. - upstream: A parent branch the source code is based on. This is the branch you pull from and push to, basically your upstream. - LTS: Long Term Support ```	/content/code_sandbox/doc/project/index.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	397
```restructuredtext .. _code-documentation: Code Documentation ################### API Documentation **************** Well documented APIs enhance the experience for developers and are an essential requirement for defining an API's success. Doxygen is a general purpose documentation tool that the zephyr project uses for documenting APIs. It generates either an on-line documentation browser (in HTML) and/or provides input for other tools that is used to generate a reference manual from documented source files. In particular, doxygen's XML output is used as an input when producing the Zephyr project's online documentation. Reference to Requirements ********************** APIs for the most part document the implementation of requirements or advertised features and can be traced back to features. We use the API documentation as the main interface to trace implementation back to documented features. This is done using custom _doxygen_ tags that reference requirements maintained somewhere else in a requirement catalogue. Test Documentation *************** To help understand what each test does and which functionality it tests we also document all test code using the same tools and in the same context and generate documentation for all unit and integration tests maintained in the same environment. Tests are documented using references to the APIs or functionality they validate by creating a link back to the APIs and by adding a reference to the original requirements. Documentation Guidelines ********************* Test Code ========= The Zephyr project uses several test methodologies, the most common being the :ref:`Ztest framework <test-framework>`. Test documentation should only be done on the entry test functions (usually prefixed with test\_) and those that are called directly by the Ztest framework. Those tests are going to appear in test reports and using their name and identifier is the best way to identify them and trace back to them from requirements. Test documentation should not interfere with the actual API documentation and needs to follow a new structure to avoid confusion. Using a consistent naming scheme and following a well-defined structure we will be able to group this documentation in its own module and identify it uniquely when parsing test data for traceability reports. Here are a few guidelines to be followed: - All test code documentation should be grouped under the ``all_tests`` doxygen group - All test documentation should be under doxygen groups that are prefixed with tests\_ The custom doxygen ``@verify`` directive signifies that a test verifies a requirement:: / * @brief Tests for the Semaphore kernel object * @defgroup kernel_semaphore_tests Semaphore * @ingroup all_tests * @{ / ... /* * @brief A brief description of the tests * Some details about the test * more details * * @verify{@req{1111}} / void test_sema_thread2thread(void) { ... } ... /* * @} / To get coverage of how an implementation or a piece of code satisfies a requirements, we use the ``satisfy`` alias in doxygen:: /* * @brief Give a semaphore. * * This routine gives @a sem, unless the semaphore is already at its maximum * permitted count. * * @note Can be called by ISRs. * * @param sem Address of the semaphore. * * @satisfy{@req{015}} / __syscall void k_sem_give(struct k_sem sem); To generate the matrix, you will first need to build the documentation, specifically you will need to build the doxygen XML output:: $ make doxygen Parse the generated XML data from doxygen to generate the traceability matrix. ```	/content/code_sandbox/doc/project/documentation.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	771
```restructuredtext .. _release_process: Release Process ############### The Zephyr project releases on a time-based cycle, rather than a feature-driven one. Zephyr releases represent an aggregation of the work of many contributors, companies, and individuals from the community. A time-based release process enables the Zephyr project to provide users with a balance of the latest technologies and features and excellent overall quality. A roughly 4-month release cycle allows the project to coordinate development of the features that have actually been implemented, allowing the project to maintain the quality of the overall release without delays because of one or two features that are not ready yet. The Zephyr release model was loosely based on the Linux kernel model: - Release tagging procedure: - linear mode on main branch, - release branches for maintenance after release tagging. - Each release period will consist of a development phase followed by a stabilization phase. Release candidates will be tagged during the stabilization phase. During the stabilization phase, only stabilization changes such as bug fixes and documentation will be merged unless granted a special exemption by the Technical Steering Committee. - Development phase: all changes are considered and merged, subject to approval from the respective maintainers. - Stabilisation phase: the release manager creates a vN-rc1 tag and the tree enters the stabilization phase - CI sees the tag, builds and runs tests; Test teams analyse the report from the build and test run and give an ACK/NAK to the build - The release owner, with test teams and any other needed input, determines if the release candidate is a go for release - If it is a go for a release, the release owner lays a tag release vN at the same point .. figure:: release_cycle.svg :align: center :alt: Release Cycle :figclass: align-center :width: 80% Release Cycle .. note:: The milestones for the current major version can be found on the `Official GitHub Wiki <path_to_url`_. Information on previous releases can be found :ref:`here <zephyr_release_notes>`. Development Phase *************** A relatively straightforward discipline is followed with regard to the merging of patches for each release. At the beginning of each development cycle, the main branch is said to be open for development. At that time, code which is deemed to be sufficiently stable (and which is accepted by the maintainers and the wide community) is merged into the mainline tree. The bulk of changes for a new development cycle (and all of the major changes) will be merged during this time. The development phase lasts for approximately three months. At the end of this time, the release owner will declare that the development phase is over and releases the first of the release candidates. For the codebase release which is destined to be 3.1.0, for example, the release which happens at the end of the development phase will be called 3.1.0-rc1. The -rc1 release is the signal that the time to merge new features has passed, and that the time to stabilize the next release of the code base has begun. Stabilization Phase *************** Over the next weeks and depending on the release milestone, only stabilization, cosmetic changes, tests, bug and doc fixes are allowed (See :ref:`table <release_milestones>` below). On occasion, more significant changes and new features will be allowed, but such occasions are rare and require a TSC approval and a justification. As a general rule, if you miss submitting your code during the development phase for a given feature, the best thing to do is to wait for the next development cycle. (An occasional exception is made for drivers for previously unsupported hardware; if they do not touch any other in-tree code, they cannot cause regressions and should be safe to add at any time). As fixes make their way into the mainline, the patch rate will slow over time. The mainline release owner releases new -rc drops once or twice a week; a normal series will get up to somewhere between -rc4 and -rc6 before the code base is considered to be sufficiently stable and the release criteria have been achieved at which point the final 3.1.0 release is made. At that point, the whole process starts over again. .. _release_quality_criteria: Release Criteria ************ The main motivation is to clearly have the criteria in place that must be met for a release. This will help define when a release is "done" in terms that most people can understand and in ways that help new people to understand the process and participate in creating successful releases: - The release criteria documents all the requirements of our target audience for each Zephyr release - The target audiences for each release can be different, and may overlap - The criteria at any given time are not set in stone: there may be requirements that have been overlooked, or that are new, and in these cases, the criteria should be expanded to ensure all needs are covered. Below is the high level criteria to be met for each release: - No blocker bugs / blocking issues - All relevant tests shall pass on ``Tier 0`` platforms - All relevant tests shall pass on Tier 0 and 1 platforms (at least 1 per architecture/architecture variant/Hardware features) - All applicable samples/tests shall build on Tiers 0, 1 and 2 - All high and critical static analysis and security issues addressed - Release Notes are up-to-date. Blocker Bugs ============ Blocker bug process kicks in during the release process and is in effect after the feature freeze milestone. An issue labeled as a blocker practically blocks a release from happening. All blocker bugs shall be resolved before a release is created. A fix for a bug that is granted `blocker` status can be merged to 'main' and included in the release all the way until the final release date. Bugs of moderate severity and higher that have impact on all users are typically the candidates to be promoted to blocker bugs Contributors and member of the release engineering team shall follow these guidelines for release blocker bugs: - Only mark bugs as blockers if the software (Zephyr) must not be released with the bug present. - All collaborators can add or remove blocking labels. - Evaluate bugs as potential blockers based on their severity and prevalence. - Provide detailed rationale whenever adding or removing a blocking label. - Ensure all blockers have the milestone tagged. - Release managers have final say on blocking status; contact them with any questions. .. _release_milestones: Release Milestones ***************** .. list-table:: Release Milestones :widths: 15 25 100 25 :header-rows: 1 * - Timeline - Checkpoint - Description - Owner * - T-5M - Planning - Finalize dates for release, Assign release owner and agree on project wide goals for this release. - TSC * - T-7W - Review target milestones - Finalize target milestones for features in flight. - Release Engineering * - T-4W - Release Announcement - Release owner announces feature freeze and timeline for release. - Release Manager * - T-3W - Feature Freeze (RC1) - No new features after RC1, ONLY stabilization and cosmetic changes, bug and doc fixes are allowed.

Release notes need to be complete by this checkpoint. Release Criteria is met. - Release Manager * - T-0W - Release - - Release Manager Releases ******* The following syntax should be used for releases and tags in Git: - Release [Major].[Minor].[Patch Level] - Release Candidate [Major].[Minor].[Patch Level]-rc[RC Number] - Tagging: - v[Major].[Minor].[Patch Level]-rc[RC Number] - v[Major].[Minor].[Patch Level] - v[Major].[Minor].99 - A tag applied to main branch to signify that work on v[Major].[Minor+1] has started. For example, v1.7.99 will be tagged at the start of v1.8 process. The tag corresponds to VERSION_MAJOR/VERSION_MINOR/PATCHLEVEL macros as defined for a work-in-progress main branch version. Presence of this tag allows generation of sensible output for "git describe" on main branch, as typically used for automated builds and CI tools. .. figure:: release_flow.png :align: center :alt: Releases :figclass: align-center :width: 80% Zephyr Code and Releases .. _release_process_lts: Long Term Support (LTS) ======================= Long-term support releases are designed to be supported and maintained for an extended period and is the recommended release for products and the auditable branch used for certification. An LTS release is defined as: - Product focused - Extended Stabilisation period: Allow for more testing and bug fixing - Stable APIs - Quality Driven Process - Long Term*: Maintained for an extended period of time (at least 2.5 years) overlapping previous LTS release for at least half a year. Product Focused +++++++++++++++ Zephyr LTS is the recommended release for product makers with an extended support and maintenance which includes general stability and bug fixes, security fixes. An LTS includes both mature and new features. API and feature maturity is documented and tracked. The footprint and scope of mature and stable APIs expands as we move from one LTS to the next giving users access to bleeding edge features and new hardware while keeping a stable foundation that evolves over time. Extended Stabilisation Period +++++++++++++++++++++++++++++ Zephyr LTS development cycle differs from regular releases and has an extended stabilization period. Feature freeze of regular releases happens 3-4 weeks before the scheduled release date. The stabilization period for LTS is extended by 3 weeks with the feature freeze occurring 6-7 weeks before the anticipated release date. The time between code freeze and release date is extended in this case. Stable APIs +++++++++++ Zephyr LTS provides a stable and long-lived foundation for developing products. To guarantee stability of the APIs and the implementation of such APIs it is required that any release software that makes the core of the OS went through the Zephyr API lifecycle and stabilized over at least 2 releases. This guarantees that we release many of the highlighted and core features with mature and well-established implementations with stable APIs that are supported during the lifetime of the release LTS. - API Freeze (LTS - 2) - All stable APIs need to be frozen 2 releases before an LTS. APIs can be extended with additional features, but the core implementation is not modified. This is valid for the following subsystems for example: - Device Drivers (i2c.h, spi.h)... - Kernel (k_): - OS services (logging,debugging, ..) - DTS: API and bindings stability - Kconfig - New APIs for experimental features can be added at any time as long as they are standalone and documented as experimental or unstable features/APIs. - Feature Freeze (LTS - 1) - No new features or overhaul/restructuring of code covering major LTS features. - Kernel + Base OS - Additional advertised LTS features - Auxiliary features on top of and/or extending the base OS and advertised LTS features can be added at any time and should be marked as experimental if applicable Quality Driven Process ++++++++++++++++++++++ The Zephyr project follows industry standards and processes with the goal of providing a quality oriented releases. This is achieved by providing the following products to track progress, integrity and quality of the software components provided by the project: - Compliance with published coding guidelines, style guides and naming conventions and documentation of deviations. - Static analysis reports - Regular static analysis on the complete tree using available commercial and open-source tools, and documentation of deviations and false positives. - Documented components and APIS - Requirements Catalog - Verification Plans - Verification Reports - Coverage Reports - Requirements Traceability Matrix (RTM) Each release is created with the above products to document the quality and the state of the software when it was released. Long Term Support and Maintenance ++++++++++++++++++++++++++++++++++ A Zephyr LTS release is published every 2 years and is branched and maintained independently from the main tree for at least 2.5 years after it was released. Support and maintenance for an LTS release stops at least half a year after the following LTS release is published. .. figure:: lts.svg :align: center :alt: Long Term Support Release :figclass: align-center :width: 80% Long Term Support Release Changes and fixes flow in both directions. However, changes from main branch to an LTS branch will be limited to fixes that apply to both branches and for existing features only. All fixes for an LTS branch that apply to the mainline tree shall be submitted to mainline tree as well. Auditable Code Base =================== An auditable code base is to be established from a defined subset of Zephyr OS features and will be limited in scope. The LTS, development tree, and the auditable code bases shall be kept in sync after the audit branch is created, but with a more rigorous process in place for adding new features into the audit branch used for certification. This process will be applied before new features move into the auditable code base. The initial and subsequent certification targets will be decided by the Zephyr project governing board. Processes to achieve selected certification will be determined by the Security and Safety Working Groups and coordinated with the TSC. Hardware Support Tiers ********************* Tier 0: Emulation Platforms =========================== - Tests are both built and run in these platforms in CI, and therefore runtime failures can block Pull Requests. - Supported by the Zephyr project itself, commitment to fix bugs in releases. - One Tier 0 platform is required for each new architecture. - Bugs reported against platforms of this tier are to be evaluated and treated as a general bug in Zephyr and should be dealt with the highest priority. Tier 1: Supported Platforms =========================== - Commitment from a specific team to run tests using twister device testing for the "Zephyr compatibility test suite" (details TBD) on a regular basis using open-source and publicly available drivers. - Commitment to fix bugs in time for releases. Not supported by "Zephyr Project" itself. - General availability for purchase - Bugs reported against platforms of this tier are to be evaluated and treated as a general bug in Zephyr and should be dealt with medium to high priority. Tier 2: Community Platforms =========================== - Platform implementation is available in upstream, no commitment to testing, may not be generally available. - Has a dedicated maintainer who commits to respond to issues / review patches. - Bugs reported against platforms of this tier are NOT considered as a general bug in Zephyr. Tier 3: Deprecated and unsupported Platforms ============================================ - Platform implementation is available, but no owner or unresponsive owner. - No commitment to support is available. - May be removed from upstream if no one works to bring it up to tier 2 or better. - Bugs reported against platforms of this tier are NOT considered as a general bug in Zephyr. Release Procedure **************** This section documents the Release manager responsibilities so that it serves as a knowledge repository for Release managers. Release Checklist ================= Each release has a GitHub issue associated with it that contains the full checklist. After a release is complete, a checklist for the next release is created. Tagging ======= The final release and each release candidate shall be tagged using the following steps: .. note:: Tagging needs to be done via explicit git commands and not via GitHub's release interface. The GitHub release interface does not generate annotated tags (it generates 'lightweight' tags regardless of release or pre-release). You should also upload your gpg public key to your GitHub account, since the instructions below involve creating signed tags. However, if you do not have a gpg public key you can opt to remove the ``-s`` option from the commands below. .. tabs:: .. tab:: Release Candidate .. note:: This section uses tagging 1.11.0-rc1 as an example, replace with the appropriate release candidate version. #. Update the version variables in the :zephyr_file:`VERSION` file located in the root of the Git repository to match the version for this release candidate. The ``EXTRAVERSION`` variable is used to identify the rc[RC Number] value for this candidate:: EXTRAVERSION = rc1 #. Post a PR with the updated :zephyr_file:`VERSION` file using ``release: Zephyr 1.11.0-rc1`` as the commit subject. Merge the PR after successful CI. #. Tag and push the version, using an annotated tag:: $ git pull $ git tag -s -m "Zephyr 1.11.0-rc1" v1.11.0-rc1 $ git push git@github.com:zephyrproject-rtos/zephyr.git v1.11.0-rc1 #. Send an email to the mailing lists (``announce`` and ``devel``) with a link to the release .. tab:: Final Release .. note:: This section uses tagging 1.11.0 as an example, replace with the appropriate final release version. When all final release criteria has been met and the final release notes have been approved and merged into the repository, the final release version will be set and repository tagged using the following procedure: #. Update the version variables in the :zephyr_file:`VERSION` file located in the root of the Git repository. Set ``EXTRAVERSION`` variable to an empty string to indicate final release:: EXTRAVERSION = #. Post a PR with the updated :zephyr_file:`VERSION` file using ``release: Zephyr 1.11.0`` as the commit subject. Merge the PR after successful CI. #. Tag and push the version, using two annotated tags:: $ git pull $ git tag -s -m "Zephyr 1.11.0" v1.11.0 $ git push git@github.com:zephyrproject-rtos/zephyr.git v1.11.0 #. Find the new ``v1.11.0`` tag at the top of the releases page and edit the release with the ``Edit tag`` button with the following: * Copy the overview of ``docs/releases/release-notes-1.11.rst`` into the release notes textbox and link to the full release notes file on docs.zephyrproject.org. #. Send an email to the mailing lists (``announce`` and ``devel``) with a link to the release ```	/content/code_sandbox/doc/project/release_process.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	4,295

Maintainers shall also serve as the areas representative on the TSC as needed. Maintainers may become voting members of the TSC under the guidelines stated in the project Charter. Collaborator: A highly involved Contributor in one or more areas. May become a Maintainer with approval of existing TSC voting members. Contributor: anyone in the community that contributes code or documentation to the project. Contributors may become Collaborators by approval of the existing Collaborators and Maintainers of the particular code base areas or subsystems. .. _contributor: Contributor +++++++++++ A Contributor is a developer who wishes to contribute to the project, at any level. Contributors are granted the following rights and responsibilities: * Right to contribute code, documentation, translations, artwork, etc. * Right to report defects (bugs) and suggestions for enhancement. * Right to participate in the process of reviewing contributions by others. * Right to initiate and participate in discussions in any communication methods. * Right to approach any member of the community with matters they believe to be important. * Right to participate in the feature development process. * Responsibility to abide by decisions, once made. They are welcome to provide new, relevant information to reopen decisions. * Responsibility for issues and bugs introduced by ones own contributions. * Responsibility to respect the rules of the community. * Responsibility to provide constructive advice whenever participating in discussions and in the review of contributions. * Responsibility to follow the projects code of conduct (path_to_url Contributors are initially only given `Read <path_to_url`_ access to the Zephyr GitHub repository. Specifically, at the Read access level, Contributors are not allowed to assign reviewers to their own pull requests. An automated process will assign reviewers. You may also share the pull request on the `Zephyr devel mailing list <path_to_url`_ or on the `Zephyr Discord Server <path_to_url`_. Contributors who show dedication and skill are granted the Triage permission level to the Zephyr GitHub repository. You may nominate yourself, or another GitHub user, for promotion to the Triage permission level by creating a GitHub issue, using the :github:`nomination template <new?assignees=&labels=Role+Nomination&template=006_nomination.md&title=>`. Contributors granted the Triage permission level are permitted to add reviewers to a pull request and can be added as a reviewer by other GitHub users. Contributor change requests or approval on pull requests are not counted with respect to accepting and merging a pull request. However, Contributors comments and requested changes should still be considered by the pull request author. .. _collaborator: Collaborator ++++++++++++ A Collaborator is a Contributor who is also responsible for the maintenance of Zephyr source code. Their opinions weigh more when decisions are made, in a fully meritocratic fashion. Collaborators have the following rights and responsibilities, in addition to those listed for Contributors: * Right to set goals for the short and medium terms for the project being maintained, alongside the Maintainer. * Responsibility to participate in the feature development process. * Responsibility to review relevant code changes within reasonable time. * Responsibility to ensure the quality of the code to expected levels. * Responsibility to participate in community discussions. * Responsibility to mentor new contributors when appropriate * Responsibility to participate in the quality verification and release process, when those happen. Contributors are promoted to the Collaborator role by adding the GitHub user name to one or more ``collaborators`` sections of the :ref:`maintainers_file` in the Zephyr repository. Collaborator change requests on pull requests should be addressed by the original submitter. In cases where the changes requested do not follow the :ref:`expectations <reviewer-expectations>` and the guidelines of the project or in cases of disagreement, it is the responsibility of the assignee to advance the review process and resolve any disagreements. Collaborator approval of pull requests are counted toward the minimum required approvals needed to merge a PR. Other criteria for merging may apply. .. _maintainer: Maintainer ++++++++++ A Maintainer is a Collaborator who is also responsible for knowing, directing and anticipating the needs of a given zephyr source code area. Maintainers have the following rights and responsibilities, in addition to those listed for Contributors and Collaborators: * Right to set the overall architecture of the relevant subsystems or areas of involvement. * Right to make decisions in the relevant subsystems or areas of involvement, in conjunction with the collaborators and submitters. See :ref:`pr_technical_escalation`. * Responsibility to convey the direction of the relevant subsystem or areas to the TSC * Responsibility to ensure all contributions of the project have been reviewed within reasonable time. * Responsibility to enforce the code of conduct. * Responsibility to triage static analysis issues in their code area. See :ref:`static_analysis`. Contributors or Collaborators are promoted to the Maintainer role by adding the GitHub user name to one or more ``maintainers`` sections of the :ref:`maintainers_file` in the Zephyr repository. Maintainer approval of pull requests are counted toward the minimum required approvals needed to merge a PR. Other criteria for merging may apply. Role Retirement ############### * Individuals elected to the following Project roles, including, Maintainer, Release Engineering Team member, Release Manager, but are no longer engaged in the project as described by the rights and responsibilities of that role, may be requested by the TSC to retire from the role they are elected. * Such a request needs to be raised as a motion in the TSC and be approved by the TSC voting members. By approval of the TSC the individual is considered to be retired from the role they have been elected. * The above applies to elected TSC Project roles that may be defined in addition. Teams and Supporting Activities ############################### Assignee ++++++++ An Assignee is one of the maintainers of a subsystem or code being changed. Assignees are set either automatically based on the code being changed or set by the other Maintainers, the Release Engineering team can set an assignee when the latter is not possible. * Responsibility to drive the pull request to a mergeable state * Right to dismiss stale and unrelated reviews or reviews not following :ref:`expectations <reviewer-expectations>` from reviewers and seek reviews from additional maintainers, developers and contributors * Right to block pull requests from being merged until issues or changes requested are addressed * Responsibility to re-assign a pull request if they are the original submitter of the code * Solicit approvals from maintainers of the subsystems affected * Responsibility to drive the :ref:`pr_technical_escalation` process Static Analysis Audit Team ++++++++++++++++++++++++++ The Static Analysis Audit team works closely with the release engineering team to ensure that static analysis defects opened during a release cycle are properly addressed. The team has the following rights and responsibilities: * Right to revert any triage in a static analysis tool (e.g: Coverity) that does not follow the project expectations. * Responsibility to inform code owners about improper classifications. * Responsibility to alert TSC if any issues are not adequately addressed by the responsible code owners.

We already require at least 2 approvals (basic four eye principle), however, such reviews and approvals might be unintentionally biased in the case where the submitter is from the same organisation as the approvers. To allow for project wide review and approvals, the merge criteria is extended with the guidelines below: * Changes or additions to common and shared code shall have approvals from different organisations (at least one approval from an organisation different than the submitters'). Common and shared code is defined as anything that does not fall under :file:`soc`, :file:`boards` and :file:`drivers//`. * Changes or additions to hardware support (driver, SoC, boards) shall at least have the merger be from a different organisation. This applies only to implementation of an API supporting vendor specific hardware and not the APIs. * Release engineers may make exceptions for areas with contributions primarily coming from one organisation and where reviews from other organisations are not possible, however, merges shall be completed by a person from a different organisation. In such cases, the minimum review period of at least 2 days shall be strictly followed to allow for additional reviews. * Release engineers shall not merge code changes originating and reviewed only by their own organisation. To be able to merge such changes, at least one review shall be from a different organisation. * A minimum review period of 2 business days, 4 hours for trivial changes (see :ref:`review_time`). * Hotfixes can be merged at any time after CI has passed and are excluded from most of the conditions listed above. * All required checks are passing: * Codeowners * Device Tree * Documentation * Gitlint * Identity/Emails * Kconfig * Checkpatch (Coding Style) * Pylint * Integration Tests (Via twister) on emulation/simulation platforms * Simulated Bluetooth Tests * Planned * Footprint * Code coverage * Coding Guidelines * Static Analysis (Coverity) * Documentation coverage (APIs) ```	/content/code_sandbox/doc/project/project_roles.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	3,512
```restructuredtext .. _dev-environment-and-tools: Development Environment and Tools ################################# Code Review ********** GitHub is intended to provide a framework for reviewing every commit before it is accepted into the code base. Changes, in the form of Pull Requests (PR) are uploaded to GitHub but don't actually become a part of the project until they've been reviewed, passed a series of checks (CI), and are approved by maintainers. GitHub is used to support the standard open source practice of submitting patches, which are then reviewed by the project members before being applied to the code base. Pull requests should be appropriately :ref:`labeled<gh_labels>`, and linked to any relevant :ref:`bug or feature tracking issues<bug_reporting>` . The Zephyr project uses GitHub for code reviews and Git tree management. When submitting a change or an enhancement to any Zephyr component, a developer should use GitHub. GitHub Actions automatically assigns a responsible reviewer on a component basis, as defined in the :zephyr_file:`MAINTAINERS.yml` file stored with the code tree in the Zephyr project repository. A limited set of release managers are allowed to merge a pull request into the main branch once reviews are complete. .. _review_time: Give reviewers time to review before code merge ================================================ The Zephyr project is a global project that is not tied to a certain geography or timezone. We have developers and contributors from across the globe. When changes are proposed using pull request, we need to allow for a minimal review time to give developers and contributors the opportunity to review and comment on changes. There are different categories of changes and we know that some changes do require reviews by subject matter experts and owners of the subsystem being changed. Many changes fall under the "trivial" category that can be addressed with general reviews and do not need to be queued for a maintainer or code-owner review. Additionally, some changes might require further discussions and a decision by the TSC or the Security working group. To summarize the above, the diagram below proposes minimal review times for each category: .. figure:: pull_request_classes.png :align: center :alt: Pull request classes :figclass: align-center Pull request classes Workflow --------- - An author of a change can suggest in his pull-request which category a change should belong to. A project maintainers or TSC member monitoring the inflow of changes can change the label of a pull request by adding a comment justifying why a change should belong to another category. - The project will use the label system to categorize the pull requests. - Changes should not be merged before the minimal time has expired. Categories/Labels ----------------- Hotfix ++++++ Any change that is a fix to an issue that blocks developers from doing their daily work, for example CI breakage, Test breakage, Minor documentation fixes that impact the user experience. Such fixes can be merged at any time after they have passed CI checks. Depending on the fix, severity, and availability of someone to review them (other than the author) they can be merged with justification without review by one of the project owners. Trivial +++++++ Trivial changes are those that appear obvious enough and do not require maintainer or code-owner involvement. Such changes should not change the logic or the design of a subsystem or component. For example a trivial change can be: - Documentation changes - Configuration changes - Minor Build System tweaks - Minor optimization to code logic without changing the logic - Test changes and fixes - Sample modifications to support additional configuration or boards etc. Maintainer +++++++++++ Any changes that touch the logic or the original design of a subsystem or component will need to be reviewed by the code owner or the designated subsystem maintainer. If the code changes is initiated by a contributor or developer other than the owner the pull request needs to be assigned to the code owner who will have to drive the pull request to a mergeable state by giving feedback to the author and asking for more reviews from other developers. Security +++++++++++ Changes that appear to have an impact to the overall security of the system need to be reviewed by a security expert from the security working group. TSC and Working Groups ++++++++++++++++++++++ Changes that introduce new features or functionality or change the way the overall system works need to be reviewed by the TSC or the responsible Working Group. For example for :ref:`breaking API changes <breaking_api_changes>`, the proposal needs to be presented in the Architecture meeting so that the relevant stakeholders are made aware of the change. A Pull-Request should have an Assignee ======================================= - An assignee to a pull request should not be the same as the author of the pull-request - An assignee to a pull request is responsible for driving the pull request to a mergeable state - An assignee is responsible for dismissing stale reviews and seeking reviews from additional developers and contributors - Pull requests should not be merged without an approval by the assignee. Pull Request should not be merged by author without review =========================================================== All pull requests need to be reviewed and should not be merged by the author without a review. The following exceptions apply: - Hot fixes: Fixing CI issues, reverts, and system breakage - Release related changes: Changing version file, applying tags and release related activities without any code changes. Developers and contributors should always seek review, however there are cases when reviewers are not available and there is a need to get a code change into the tree as soon as possible. Reviewers shall not 'Request Changes' without comments or justification ======================================================================= Any change requests (-1) on a pull request have to be justified. A reviewer should avoid blocking a pull-request with no justification. If a reviewer feels that a change should not be merged without their review, then: Request change of the category: for example: - Trivial -> Maintainer - Assign Pull Request to yourself, this will mean that a pull request should not be merged without your approval. Pull Requests should have at least 2 approvals before they are merged ====================================================================== A pull-request shall be merged only with two positive reviews (approval). Beside the person merging the pull-request (merging != approval), two additional approvals are required to be able to merge a pull request. The person merging the request can merge without approving or approve and merge to get to the 2 approvals required. Reviewers should keep track of pull requests they have provided feedback to =========================================================================== If a reviewer has requested changes in a pull request, he or she should monitor the state of the pull request and/or respond to mention requests to see if his feedback has been addressed. Failing to do so, negative reviews shall be dismissed by the assignee or an owner of the repository. Reviews will be dismissed following the criteria below: - The feedback or concerns were visibly addressed by the author - The reviewer did not revisit the pull request after 2 week and multiple pings by the author - The review is unrelated to the code change or asking for unjustified structural changes such as: - Split the PR - Can you fix this unrelated code that happens to appear in the diff - Can you fix unrelated issues - Etc. Closing Stale Issues and Pull Requests ======================================= - The Pull requests and issues sections on Github are NOT discussion forums. They are items that we need to execute and drive to closure. Use the mailing lists for discussions. - In case of both issues and pull-requests the original poster needs to respond to questions and provide clarifications regarding the issue or the change. After one week without a response to a request, a second attempt to elicit a response from the contributor will be made. After one more week without a response the item may be closed (draft and DNM tagged pull requests are excluded). Continuous Integration ********************* All changes submitted to GitHub are subject to tests that are run on emulated platforms and architectures to identify breakage and regressions that can be immediately identified. Testing using Twister additionally performs build tests of all boards and platforms. Documentation changes are also verified through review and build testing to verify doc generation will be successful. Any failures found during the CI test run will result in a negative review assigned automatically by the CI system. Developers are expected to fix issues and rework their patches and submit again. The CI infrastructure currently runs the following tests: - Run ``checkpatch`` for code style issues (can vote -1 on errors; see note) - Gitlint: Git commit style based on project requirements - Run ``twister`` script - Run kernel tests in QEMU (can vote -1 on errors) - Build various samples for different boards (can vote -1 on errors) - Verify documentation builds correctly. .. note:: ``checkpatch`` is a Perl script that uses regular expressions to extract information that requires a C language parser to process accurately. As such it sometimes issues false positives. Known cases include constructs like: .. code-block:: c static uint8_t __aligned(PAGE_SIZE) page_pool[PAGE_SIZE * POOL_PAGES]; IOPCTL_Type base = config->base; Both lines produce a diagnostic regarding spaces around the ```` operator: the first is misidentified as a pointer type declaration that would be correct as ``PAGE_SIZE POOL_PAGES`` while the second is misidentified as a multiplication expression that would be correct as ``IOPCTL_Type base``. Maintainers can override the -1 in cases where the CI infrastructure gets the wrong answer. .. _gh_labels: Labeling issues and pull requests in GitHub ***************************************** The project uses GitHub issues and pull requests (PRs) to track and manage daily and long-term work and contributions to the Zephyr project. We use GitHub labels** to classify and organize these issues and PRs by area, type, priority, and more, making it easier to find and report on relevant items. All GitHub issues or pull requests must be appropriately labeled. Issues and PRs often have multiple labels assigned, to help classify them in the different available categories. When reviewing a PR, if it has missing or incorrect labels, maintainers shall fix it. This saves us all time when searching, reduces the chances of the PR or issue being forgotten, speeds up reviewing, avoids duplicate issue reports, etc. These are the labels we currently have, grouped by applicability: Labels applicable to issues only ================================ .. list-table:: :header-rows: 1 * - Label - Description * - :guilabel:`priority: {high\|medium\|low}` - To classify the impact and importance of a bug or :ref:`feature <feature-tracking>`. Note: Issue priorities are generally set or changed during the bug-triage or TSC meetings. * - :guilabel:`Regression` - Something, which was working, but does not anymore (bug subtype). * - :guilabel:`Enhancement` - Changes/Updates/Additions to existing :ref:`features <feature-tracking>`. * - :guilabel:`Feature request` - A request for a new :ref:`feature <feature-tracking>`. * - :guilabel:`Feature` - A :ref:`planned feature<feature-tracking>` with a milestone. * - :guilabel:`Hardware Support` - Covers porting an existing feature (including Zephyr itself) to new hardware. * - :guilabel:`Duplicate` - This issue is a duplicate of another issue (please specify). * - :guilabel:`Good first issue` - Good for a first time contributor to take. * - :guilabel:`Release Notes` - Issues that need to be mentioned in release notes as known issues with additional information. Any issue must be classified and labeled as either Bug, Enhancement, RFC, Feature, Feature Request or Hardware Support. More information on how feature requests are handled and become features can be found in :ref:`Feature Tracking<feature-tracking>`. Labels applicable to pull requests only ======================================= The issue or PR describes a change to a stable API. .. list-table:: :header-rows: 1 * - Label - Description * - :guilabel:`Hotfix` - Fix for an issue blocking development. * - :guilabel:`Trivial` - Simple changes that can have shorter review time and be reviewed by anyone, i.e. typos, straightforward one-liner bug fixes, etc. * - :guilabel:`Maintainer` - Maintainer review required. * - :guilabel:`Security Review` - To be reviewed by a security expert. * - :guilabel:`DNM` - This PR should not be merged (Do Not Merge). For work in progress, GitHub "draft" PRs are preferred. * - :guilabel:`Needs review` - The PR needs attention from the maintainers. * - :guilabel:`Backport` - The PR is a backport or should be backported. * - :guilabel:`Licensing` - The PR has licensing issues which require a licensing expert to review it. .. note:: For all labels applicable to PRs: Please note that the label, together with PR complexity, affects how long a merge should be held to ensure proper review. See :ref:`review process <review_time>` for details. Labels applicable to both pull requests and issues ================================================== .. list-table:: :header-rows: 1 * - Label - Description * - :guilabel:`area: {area-name}` - Indicates Zephyr subsystems (e.g, :guilabel:`area: Kernel`, :guilabel:`area: I2C`, :guilabel:`area: Memory Management`), project functions (e.g., :guilabel:`area: Debugging`, :guilabel:`area: Documentation`, :guilabel:`area: Process`), or other categories (e.g., :guilabel:`area: Coding Style`, :guilabel:`area: MISRA-C`) affected by the bug or the pull request. An area maintainer should be able to filter by an area label and find all issues and PRs which relate to that area. * - :guilabel:`platform: {platform-name}` - An issue or PR which affects only a particular platform. * - :guilabel:`dev-review` - The issue is to be discussed in the following `dev-review`_ if time permits. .. _`dev-review`: path_to_url#zephyr-dev-meeting * - :guilabel:`TSC` - TSC stands for Technical Steering Committee. The issue is to be discussed in the following `TSC meeting`_ if time permits. .. _`TSC meeting`: path_to_url#technical-steering-committee-tsc * - :guilabel:`Breaking API Change` - The issue or PR describes a breaking change to a stable API. See additional information in :ref:`breaking_api_changes`. * - :guilabel:`bug` - The issue is a bug, or the PR is fixing a bug. * - :guilabel:`Coverity` - A Coverity detected issue or its fix. * - :guilabel:`Waiting for response` - The Zephyr developers are waiting for the submitter to respond to a question, or address an issue. * - :guilabel:`Blocked` - Blocked by another PR or issue. * - :guilabel:`Stale` - An issue or a PR which seems abandoned, and requires attention by the author. * - :guilabel:`In progress` - For PRs: is work in progress and should not be merged yet.

```restructuredtext .. _communication-and-collaboration: Communication and Collaboration ############################### The `Zephyr Discord Server <path_to_url`_ is the primary chat forum used by Zephyr developers, contributors, and users. The `Zephyr project mailing lists <path_to_url`_ are used as an additional communication tool by project members, contributors, and the community. There are specialized mailing lists for specific interests. Several lists are public and open. Mailing lists are always available for use in situations where Discord is unavailable or an unsuitable forum. In general, bug reports and other issues should be reported as `GitHub Issues <path_to_url`_ and not broadcasted to the mailing list. The same applies to code reviews. ```	/content/code_sandbox/doc/project/communication.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	157

```restructuredtext Technical Steering Committee (TSC) ******************************** TSC Member Role ############### The TSC role and its responsibilities is defined in the `Zephyr project charter`_. Membership ++++++++++ A TSC member plays a pivotal role in shaping the technical direction of the Zephyr Project. TSC members work collaboratively with other TSC members, contributors, and stakeholders to ensure the project's success and sustainability. By fulfilling the rights and responsibilities below, TSC members contribute to the overall success and growth of the Zephyr Project, ensuring that it remains a vibrant and thriving open-source community for years to come. Rights ------ Decision Making Participate in key decisions related to the project's technical direction, including architectural changes, feature additions, and release planning. Voting Exercise voting rights on important matters discussed within the TSC, including feature proposals, code contributions, and community initiatives. Access Gain access to relevant project repositories, documentation, and communication channels to stay informed and contribute effectively. Leadership Take on leadership roles within working groups or subcommittees dedicated to specific technical areas or initiatives. Representation Act as a representative of the broader Zephyr community, advocating for the interests of contributors, users, and stakeholders. Responsibilities ---------------- TSC members are expected to fulfill the following responsibilities, though it is not mandatory to fulfill all: Technical Oversight Provide guidance and oversight on technical matters, ensuring alignment with project goals, standards, and best practices through active participation as core members in working groups and committees. Code Review Participate in code reviews to maintain code quality, consistency, and compatibility with project standards. Community Engagement Engage with the community through forums, mailing lists, conferences, and other channels to foster collaboration, address concerns, and gather feedback. Documentation Contribute to the development and maintenance of project documentation, including technical guides, API references, and best practices. Release Management Collaborate with the release manager and other stakeholders to plan and coordinate project releases, ensuring timely delivery and quality assurance. Contributor Support Support and mentor new contributors, helping them navigate the project's codebase, processes, and community norms. Issue Triage Assist in triaging and prioritizing issues reported by users and contributors, facilitating timely resolution and communication. Compliance and Licensing Ensure compliance with project licensing requirements and open-source best practices, addressing any licensing-related issues that may arise. Conflict Resolution Facilitate constructive discussions and resolution of technical disagreements or conflicts within the community, promoting a healthy and inclusive environment. Continuous Improvement Continuously seek opportunities to improve project governance, processes, and infrastructure, driving innovation and sustainability. Appointed TSC Members +++++++++++++++++++++ See `Zephyr project charter`_ for more details. - Appointed TSC members have no term limits besides the term of their employment at the organization they represent or their organization's membership in the Zephyr Project. - Appointed TSC members can select an Alternate from the same organization. Elected TSC Members +++++++++++++++++++ Per the `Zephyr project charter`_, TSC members can nominate representatives from the technical community at the rate of no more than one per quarter. - Majority vote is required to confirm a candidate. - Once elected, a TSC member serves for 2 years. - Elected TSC members do not have the right to appoint an Alternate. - To ensure continuity of the TSC, at the end of the 2 year term, the TSC is required to reconfirm the membership of elected members. If the elected member declines a new term or if the TSC fails to reconfirm the term, the seat will be open for new nominations. - If an elected TSC member resigns before the end of the 2 year term, their spot will be open for new members outside of the quarterly nomination limit. The elected member will serve a 2 year term. - The TSC has the right to terminate elected members who become inactive and are not fulfilling the responsibilities of TSC members as described in this document. - The number of elected members shall not exceed 20% of the total of appointed members. - Existing TSC members who were elected before May 2024 shall be re-confirmed after completing the 2 year term since they were first elected. Suspensions +++++++++++ As noted under Section 8b of the Project Charter, voting rights for a representative who misses three consecutive meetings are subject to suspension and suspended representatives do not count towards the quorum requirement. A representatives suspension will end and voting rights be restored at the start of the next attended meeting. The TSC enforces the suspension policy for voting members who miss three consecutive TSC weekly meetings. Multi-day meetings (F2F events) are counted as "one" meeting. The TSC voted on February 16, 2022 to discontinue default enforcement of the suspension policy. The TSC voted on January 18, 2023 to re-enact default enforcement of the suspension policy. Notice of suspension will be sent to representatives who miss three consecutive meetings, noting that rights will be restored upon next attendance of a TSC meeting. .. note:: As per Section 4b of the Project Charter, Platinum and Silver Members may choose to opt out of a voting seat on the TSC. Members who opt out and then wish to reclaim their seat later will have their voting rights restored at the start of the second consecutive meeting attended following notification to the TSC Chair. Voting ++++++ Voting in the Zephyr Project is defined under Section 8 of the Project Charter. Additional points of clarity / TSC interpretation have been added below. The Governing Board may opt to update the Charter to include the below refinements. Until then, additional clarifications (if/where needed) will be discussed in the Process Working Group, and approved in the TSC. - TSC In-Meeting Voting For items requesting an in-meeting vote of the Zephyr Technical Steering Committee (TSC), assuming quorum requirements have been met, the default voting mechanism will be a verbal motion to determine if there is general consensus. - If there are no objections to a motion being brought forward, general consensus is assumed and the motion passes. - Should there be any objections raised, the vote will move to email, and be executed using the Voting Guidelines outlined in Section 8 of the Project Charter. - Should a motion be deemed urgent by the TSC Chair, and assuming quorum requirements have been met, the Chair may call for a roll call vote in-meeting. Voting Options -------------- - Voting Options are: - "Yes", - "No" or - "Abstain" Abstention ---------- Abstentions do not count in tallying the vote negatively or positively; when members abstain, they are in effect attending only to contribute to a quorum. Abstentions do not impact the number of votes needed to decide a vote. Quorum ------ Quorum for TSC meetings shall require 60% of the voting representatives... (ref 8b of the Charter) Decisions --------- Decisions by vote shall be based on a majority vote, provided that at least sixty percent (60%) of the TSC** representatives must be either present or participating electronically or by written action in order to conduct a valid vote. (ref 8c of the Charter) Example A: 40 eligible TSC voters. 3 abstain from a vote on a motion. 12 vote Yes. 11 vote No. Quorum reached: 26 votes cast (quorum = 60% of 40 = 24) Majority vote: 12 Yes vs. 11 No. Yes wins. Motion adopted. Example B: 40 eligible TSC voters. 5 abstain from a vote on a motion. 12 vote Yes. 6 vote No. Quorum reached? 23 votes cast (quorum = 60% of 40 = 24) Vote is not valid. Quorum not reached. Example C: 40 eligible TSC voters. 21 abstain from a vote on a motion. 2 vote Yes. 1 votes No. Quorum reached? 24 votes cast (quorum = 60% of 40 = 24) Majority vote: 2 Yes vs. 1 No. Yes wins. Immutable Votes +++++++++++++++ Votes are considered immutable once cast. A voter may not change their vote, once cast, between the time a Motion is brought forth and the time at which results are announced. .. _Zephyr project charter: path_to_url ```	/content/code_sandbox/doc/project/tsc.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	1,905

```restructuredtext :orphan: .. _migration_3.5: Migration guide to Zephyr v3.5.0 ################################ This document describes the changes required or recommended when migrating your application from Zephyr v3.4.0 to Zephyr v3.5.0. Any other changes (not directly related to migrating applications) can be found in the :ref:`release notes<zephyr_3.5>`. Required changes **************** Kernel ====== * The kernel :c:func:`k_mem_slab_free` function has changed its signature, now taking a ``void mem`` pointer instead of a ``void mem`` double-pointer. The new signature will not immediately trigger a compiler error or warning, instead likely causing a invalid memory access at runtime. A new ``_ASSERT`` statement, that you can enable with :kconfig:option:`CONFIG_ASSERT`, will detect if you pass the function memory not belonging to the memory blocks in the slab. :c:macro:`CONTAINER_OF` now performs type checking, this was very commonly misused to obtain user structure from :c:struct:`k_work` pointers without passing from :c:struct:`k_work_delayable`. This would now result in a build error and have to be done correctly using :c:func:`k_work_delayable_from_work`. C Library ========= * The default C library used on most targets has changed from the built-in minimal C library to Picolibc. While both provide standard C library interfaces and shouldn't cause any behavioral regressions for applications, there are a few side effects to be aware of when migrating to Picolibc. * Picolibc enables thread local storage (:kconfig:option:`CONFIG_THREAD_LOCAL_STORAGE`) where supported. This changes some internal operations within the kernel that improve performance using some TLS variables. Zephyr places TLS variables in the memory reserved for the stack, so stack usage for every thread will increase by 8-16 bytes. * Picolibc uses the same malloc implementation as the minimal C library, but the default heap size depends on which C library is in use. When using the minimal C library, the default heap is zero bytes, which means that malloc will always fail. When using Picolibc, the default is 16kB with :kconfig:option:`CONFIG_MMU` or :kconfig:option:`ARCH_POSIX`, 2kB with :kconfig:option:`CONFIG_USERSPACE` and :kconfig:option:`CONFIG_MPU_REQUIRES_POWER_OF_TWO_ALIGNMENT`. For all other targets, the default heap uses all remaining memory on the system. You can change this by adjusting :kconfig:option:`CONFIG_COMMON_LIBC_MALLOC_ARENA_SIZE`. * Picolibc can either be built as part of the OS build or pulled from the toolchain. When building as part of the OS, the build will increase by approximately 1000 files. * When using the standard C++ library with Picolibc, both of those must come from the toolchain as the standard C++ library depends upon the C library ABI. * Picolibc removes the ``-ffreestanding`` compiler option. This allows significant compiler optimization improvements, but also means that the compiler will now warn about declarations of `main` which don't conform to the Zephyr required type -- ``int main(void)``. * Picolibc has four different printf/scanf variants supported in Zephyr, 'double', 'long long', 'integer', and 'minimal. 'double' offers a complete printf implementation with exact floating point in decimal and hexadecimal formats, full integer support including long long, C99 integer size specifiers (j, z, t) and POSIX positional arguments. 'long long' mode removes float support, 'integer' removes long long support while 'minimal' mode also removes support for format modifiers and positional arguments. Building the library as a module allows finer control over the feature set provided at each level. * Picolibc's default floating point input/output code is larger than the minimal C library version (this is necessary to conform with the C language "round trip" requirements for these operations). If you use :kconfig:option:`CONFIG_CBPRINTF_FP_SUPPORT`, you will see increased memory usage unless you also disable :kconfig:option:`CONFIG_PICOLIBC_IO_FLOAT_EXACT`, which switches Picolibc to a smaller, but inexact conversion algorithm. This requires building Picolibc as a module. Optional Modules ================ The following modules have been made optional and are not downloaded with `west update` by default anymore: * ``chre`` * ``lz4`` * ``nanopb`` * ``psa-arch-tests`` * ``sof`` * ``tf-m-tests`` * ``tflite-micro`` * ``thrift`` * ``zscilib`` To enable them again use the ``west config manifest.project-filter -- +<module name>`` command, or ``west config manifest.group-filter -- +optional`` to enable all optional modules, and then run ``west update`` again. Device Drivers and Device Tree ============================== * ``zephyr,memory-region-mpu`` was renamed ``zephyr,memory-attr`` and its type moved from 'enum' to 'int'. To have a seamless conversion this is the required change in the DT: .. code-block:: none - "RAM" -> <( DT_MEM_ARM(ATTR_MPU_RAM) )> - "RAM_NOCACHE" -> <( DT_MEM_ARM(ATTR_MPU_RAM_NOCACHE) )> - "FLASH" -> <( DT_MEM_ARM(ATTR_MPU_FLASH) )> - "PPB" -> <( DT_MEM_ARM(ATTR_MPU_PPB) )> - "IO" -> <( DT_MEM_ARM(ATTR_MPU_IO) )> - "EXTMEM" -> <( DT_MEM_ARM(ATTR_MPU_EXTMEM) )> * Device dependencies (incorrectly referred as "device handles" in some areas) are now an optional feature enabled by :kconfig:option:`CONFIG_DEVICE_DEPS`. This means that an extra linker stage is no longer necessary if this option is not enabled. * On all STM32 ADC, it is no longer possible to read sensor channels (Vref, Vbat or temperature) using the ADC driver. The dedicated sensor driver should be used instead. This change is due to a limitation on STM32F4 where the channels for temperature and Vbat are identical, and the impossibility of determining what we want to measure using solely the ADC API. * The RAM disk driver has been changed to support multiple instances and instantiation using devicetree. As a result, Kconfig option :kconfig:option:`CONFIG_DISK_RAM_VOLUME_SIZE` and Kconfig option :kconfig:option:`CONFIG_DISK_RAM_VOLUME_NAME` are removed, and the application using the RAM disk must instantiate it using devicetree, as in the following example: .. code-block:: devicetree / { ramdisk0 { compatible = "zephyr,ram-disk"; disk-name = "RAM"; sector-size = <512>; sector-count = <192>; }; }; * The :dtcompatible:`goodix,gt911`, :dtcompatible:`xptek,xpt2046` and :dtcompatible:`hynitron,cst816s` drivers have been converted from Kscan to Input, they can still be used with Kscan applications by adding a :dtcompatible:`zephyr,kscan-input` node. * The ``zephyr,gpio-keys`` binding has been merged into :dtcompatible:`gpio-keys` and the callback definition has been renamed from ``INPUT_LISTENER_CB_DEFINE`` to :c:macro:`INPUT_CALLBACK_DEFINE`. * The :dtcompatible:`ti,bq274xx` driver was using incorrect units for capacity and power channels, these have been fixed and scaled by x1000 factor from the previous implementation, any application using them has to be changed accordingly. * The configuration options for the SSD1306 display driver can now be provided via the Devicetree binding :dtcompatible:`solomon,ssd1306fb`. The following Kconfig options: ``CONFIG_SSD1306_DEFAULT``, ``CONFIG_SSD1306_SH1106_COMPATIBLE``, and ``CONFIG_SSD1306_REVERSE_MODE`` have been removed. * You can remove ``CONFIG_SSD1306_DEFAULT`` without any other modification. * ``CONFIG_SSD1306_SH1106_COMPATIBLE`` was used to assert that the device is (compatible with) SH1106. This has been replaced by a dedicated dts compatible declaration. You may update an existing sh1106 node to change the ``compatible`` designation from :dtcompatible:`solomon,ssd1306fb` to :dtcompatible:`sinowealth,sh1106`. * ``CONFIG_SSD1306_REVERSE_MODE`` is now set using the ``inversion-on`` property of the devicetree node. * GPIO drivers not implementing IRQ related operations must now provide ``NULL`` to the relevant operations: ``pin_interrupt_configure``, ``manage_callback``, ``get_pending_int``. The public API will return ``-ENOSYS`` when these are not available, instead of ``-ENOTSUP``. * STM32 Ethernet driver was misusing :c:func:`hwinfo_get_device_id` to generate last 3 bytes of mac address, resulting in a high risk of collision when using SoCs from the same lot. This is now fixed to use the whole range of entropy available from the unique ID (96 bits). Devices using unique ID based mac address will see last 3 bytes of their MAC address modified by this change. * On all STM32 (except F1x and F37x series), two new required properties have been added to ADC to configure the source clock and the prescaler. ``st,adc-clock-source`` allows choosing either synchronous or asynchronous clock source. ``st,adc-prescaler`` allows setting the value of the prescaler for the chosen clock source. Not all combinations are allowed. Refer to the appropriate RefMan for more information. When choosing asynchronous clock, the choice of the kernel source clock is made in the ``clocks`` node as it is done for other peripherals, for example, to select HSI16 as clock source for STM32G0: .. code-block:: devicetree &adc { clocks = <&rcc STM32_CLOCK_BUS_APB1_2 0x00100000>, <&rcc STM32_SRC_HSI ADC_SEL(2)>; }; * On NXP boards with LPC DMA, the DMA controller node used to have its ``dma-channels`` property set in the board DTS as a way to configure the amount of structures the driver will allocate. This did not match the zephyr dma-controller binding, so this property is now fixed and set in the SOC devicetree definition. Downstream boards should not override this property and instead use the new driver Kconfig :kconfig:option:`CONFIG_DMA_MCUX_LPC_NUMBER_OF_CHANNELS_ALLOCATED`. * The LPC55XXX series SOC (except LPC55S06) default main clock has been updated to PLL1 source from XTAL32K running at 144MHZ. If the new kconfig option :kconfig:option:`CONFIG_INIT_PLL1` is disabled then the main clock is muxed to FRO_HR as before. * The Kconfig option ``CONFIG_GPIO_NCT38XX_INTERRUPT`` has been renamed to :kconfig:option:`CONFIG_GPIO_NCT38XX_ALERT`. * The CAN controller timing API functions :c:func:`can_set_timing` and :c:func:`can_set_timing_data` no longer fallback to the (Re-)Synchronization Jump Width (SJW) value set in the devicetree properties for the given CAN controller upon encountering an SJW value corresponding to ``CAN_SJW_NO_CHANGE`` (which is no longer available). The caller will therefore need to fill in the ``sjw`` field in :c:struct:`can_timing`. To aid in this, the :c:func:`can_calc_timing` and :c:func:`can_calc_timing_data` functions now automatically calculate a suitable SJW. The calculated SJW can be overwritten by the caller if needed. The CAN controller API functions :c:func:`can_set_bitrate` and :c:func:`can_set_bitrate_data` now also automatically calculate a suitable SJW, but their SJW cannot be overwritten by the caller. * The CAN ISO-TP message configuration in :c:struct:`isotp_msg_id` is changed to use the following flags instead of bit fields: * :c:macro:`ISOTP_MSG_EXT_ADDR` to enable ISO-TP extended addressing * :c:macro:`ISOTP_MSG_FIXED_ADDR` to enable ISO-TP fixed addressing * :c:macro:`ISOTP_MSG_IDE` to use extended (29-bit) CAN IDs The two new flags :c:macro:`ISOTP_MSG_FDF` and :c:macro:`ISOTP_MSG_BRS` were added for CAN FD mode. * NXP i.MX RT based boards should now enable :kconfig:option:`CONFIG_DEVICE_CONFIGURATION_DATA` at the board level when using a DCD with the RT bootrom, and enable :kconfig:option:`CONFIG_NXP_IMX_EXTERNAL_SDRAM` when using external SDRAM via the SEMC * NXP i.MX RT11xx series SNVS pin control name identifiers have been updated to match with the source data for these SOCs. The pin names have had the suffix ``dig`` added. For example, ``iomuxc_snvs_wakeup_gpio13_io00`` has been renamed to ``iomuxc_snvs_wakeup_dig_gpio13_io00`` Power Management ================ * Platforms that implement power management hooks must explicitly select :kconfig:option:`CONFIG_HAS_PM` in Kconfig. This is now a dependency of :kconfig:option:`CONFIG_PM`. Before this change all platforms could enable :kconfig:option:`CONFIG_PM` because empty weak stubs were provided, however, this is no longer supported. As a result of this change, power management hooks are no longer defined as weaks. * Multiple platforms no longer support powering the system off using :c:func:`pm_state_force`. The new :c:func:`sys_poweroff` API must be used. Migrated platforms include Nordic nRF, STM32, ESP32 and TI CC13XX/26XX. The new API is independent from :kconfig:option:`CONFIG_PM`. It requires :kconfig:option:`CONFIG_POWEROFF` to be enabled, which depends on :kconfig:option:`CONFIG_HAS_POWEROFF`, an option selected by platforms implementing the required new hooks. Bootloader ========== * The :kconfig:option:`CONFIG_BOOTLOADER_SRAM_SIZE` default value is now ``0`` (was ``16``). Bootloaders that use a part of the SRAM should set this value to an appropriate size. :github:`60371` Bluetooth ========= * The ``accept()`` callback's signature in :c:struct:`bt_l2cap_server` has changed to ``int (accept)(struct bt_conn conn, struct bt_l2cap_server server, struct bt_l2cap_chan chan)``, adding a new ``server`` parameter pointing to the :c:struct:`bt_l2cap_server` structure instance the callback relates to. :github:`60536` Networking ========== A new networking Kconfig option :kconfig:option:`CONFIG_NET_INTERFACE_NAME` defaults to ``y``. The option allows user to set a name to a network interface. During system startup a default name is assigned to the network interface like ``eth0`` to the first Ethernet network interface. The option affects the behavior of ``SO_BINDTODEVICE`` BSD socket option. If the Kconfig option is set to ``n``, which is how the system worked earlier, then the name of the device assigned to the network interface is used by the ``SO_BINDTODEVICE`` socket option. If the Kconfig option is set to ``y`` (current default), then the network interface name is used by the ``SO_BINDTODEVICE`` socket option. * Ethernet PHY devicetree bindings were updated to use the standard ``reg`` property for the PHY address instead of a custom ``address`` property. As a result, MDIO controller nodes now require ``#address-cells`` and ``#size-cells`` properties. Similarly, Ethernet PHY devicetree nodes and corresponding driver were updated to consistently use the node name ``ethernet-phy`` instead of ``phy``. Devicetrees and overlays must be updated accordingly: .. code-block:: devicetree mdio { compatible = "mdio-controller"; #address-cells = <1>; #size-cells = <0>; ethernet-phy@0 { compatible = "ethernet-phy"; reg = <0>; }; }; Other Subsystems ================ * ZBus runtime observers implementation now relies on the HEAP memory instead of a memory slab. Thus, zbus' configuration (kconfig) related to runtime observers has changed. To keep your runtime observers code working correctly, you need to: - Replace the integer ``CONFIG_ZBUS_RUNTIME_OBSERVERS_POOL_SIZE`` with the boolean :kconfig:option:`CONFIG_ZBUS_RUNTIME_OBSERVERS`; - Set the HEAP size with the :kconfig:option:`CONFIG_HEAP_MEM_POOL_SIZE`. * The zbus VDED delivery sequence has changed. Check the :ref:`documentation<zbus delivery sequence>` to verify if it will affect your code. * MCUmgr SMP version 2 error codes entry has changed due to a collision with an existing response in shell_mgmt. Previously, these errors had the entry ``ret`` but now have the entry ``err``. ``smp_add_cmd_ret()`` is now deprecated and :c:func:`smp_add_cmd_err` should be used instead, ``MGMT_CB_ERROR_RET`` is now deprecated and :c:enumerator:`MGMT_CB_ERROR_ERR` should be used instead. SMP version 2 error code defines for in-tree modules have been updated to replace the ``_RET_RC_`` parts with ``_ERR_``. * MCUmgr SMP version 2 error translation (to legacy MCUmgr error code) is now handled in function handlers by setting the ``mg_translate_error`` function pointer of :c:struct:`mgmt_group` when registering a group. See :c:type:`smp_translate_error_fn` for function details. Any SMP version 2 handlers made for Zephyr 3.4 need to be updated to include these translation functions when the groups are registered. ARM === * ARM SoC initialization routines no longer need to call `NMI_INIT()`. The macro call has been removed as it was not doing anything useful. RISC V ====== * The :kconfig:option:`CONFIG_RISCV_MTVEC_VECTORED_MODE` Kconfig option was renamed to :kconfig:option:`CONFIG_RISCV_VECTORED_MODE`. Recommended Changes ******************* * Setting the GIC architecture version by selecting :kconfig:option:`CONFIG_GIC_V1`, :kconfig:option:`CONFIG_GIC_V2` and :kconfig:option:`CONFIG_GIC_V3` directly in Kconfig has been deprecated. The GIC version should now be specified by adding the appropriate compatible, for example :dtcompatible:`arm,gic-v2`, to the GIC node in the device tree. * Nordic nRF based boards using :kconfig:option:`CONFIG_NFCT_PINS_AS_GPIOS` to configure NFCT pins as GPIOs, should instead set the new UICR ``nfct-pins-as-gpios`` property in devicetree. It can be set like this in the board devicetree files: .. code-block:: devicetree &uicr { nfct-pins-as-gpios; }; * Nordic nRF based boards using :kconfig:option:`CONFIG_GPIO_AS_PINRESET` to configure reset GPIO as nRESET, should instead set the new UICR ``gpio-as-nreset`` property in devicetree. It can be set like this in the board devicetree files: .. code-block:: devicetree &uicr { gpio-as-nreset; }; * The :kconfig:option:`CONFIG_MODEM_GSM_PPP` modem driver is obsolete. Instead the new :kconfig:option:`CONFIG_MODEM_CELLULAR` driver should be used. As part of this :kconfig:option:`CONFIG_GSM_MUX` and :kconfig:option:`CONFIG_UART_MUX` are being marked as deprecated as well. The new modem subsystem :kconfig:option:`CONFIG_MODEM_CMUX` and :kconfig:option:`CONFIG_MODEM_PPP` should be used instead. * Device drivers should now be restricted to ``PRE_KERNEL_1``, ``PRE_KERNEL_2`` and ``POST_KERNEL`` initialization levels. Other device initialization levels, including ``EARLY``, ``APPLICATION``, and ``SMP``, have been deprecated and will be removed in future releases. Note that these changes do not apply to initialization levels used in the context of the ``init.h`` API, e.g. :c:macro:`SYS_INIT`. * The following CAN controller devicetree properties are now deprecated in favor specifying the initial CAN bitrate using the ``bus-speed``, ``sample-point``, ``bus-speed-data``, and ``sample-point-data`` properties: * ``sjw`` * ``prop-seg`` * ``phase-seg1`` * ``phase-seg1`` * ``sjw-data`` * ``prop-seg-data`` * ``phase-seg1-data`` * ``phase-seg1-data`` * ``<zephyr/arch/arm/aarch32/cortex_a_r/cmsis.h>`` and ``<zephyr/arch/arm/aarch32/cortex_m/cmsis.h>`` are now deprecated in favor of including ``<cmsis_core.h>`` instead. The new header is part of the CMSIS glue code in the ``modules`` directory. * Random API header ``<zephyr/random/rand32.h>`` is deprecated in favor of ``<zephyr/random/random.h>``. The old header will be removed in future releases and its usage should be avoided. ```	/content/code_sandbox/doc/releases/migration-guide-3.5.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	5,098

The following sections provide detailed lists of changes by component. Security Vulnerability Related ****************************** The following CVEs are addressed by this release: More detailed information can be found in: path_to_url * CVE-2023-1901: Under embargo until 2023-07-04 * CVE-2023-1902: Under embargo until 2023-07-04 API Changes *********** Changes in this release ======================= * Any applications using the mcuboot image manager (:kconfig:option:`CONFIG_MCUBOOT_IMG_MANAGER`) will now need to also select :kconfig:option:`CONFIG_FLASH_MAP` and :kconfig:option:`CONFIG_STREAM_FLASH`, this prevents a cmake dependency loop if the image manager Kconfig is enabled manually without also manually enabling the other options. * Including hawkbit in an application now requires additional Kconfig options to be selected, previously these options would have been selected automatically but have changed from ``select`` options in Kconfig files to ``depends on``: +--------------------------------------------------+ \| :kconfig:option:`CONFIG_NVS` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_FLASH` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_FLASH_MAP` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_STREAM_FLASH` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_REBOOT` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_HWINFO` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_NET_TCP` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_NET_SOCKETS` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_IMG_MANAGER` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_NETWORKING` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_HTTP_CLIENT` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_DNS_RESOLVER` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_JSON_LIBRARY` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_NET_SOCKETS_POSIX_NAMES` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_BOOTLOADER_MCUBOOT` \| +--------------------------------------------------+ * Including updatehub in an application now requires additional Kconfig options to be selected, previously these options would have been selected automatically but have changed from ``select`` options in Kconfig files to ``depends on``: +--------------------------------------------------+ \| :kconfig:option:`CONFIG_FLASH` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_STREAM_FLASH` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_FLASH_MAP` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_REBOOT` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_MCUBOOT_IMG_MANAGER` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_IMG_MANAGER` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_IMG_ENABLE_IMAGE_CHECK` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_BOOTLOADER_MCUBOOT` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_MPU_ALLOW_FLASH_WRITE` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_NETWORKING` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_NET_UDP` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_NET_SOCKETS` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_NET_SOCKETS_POSIX_NAMES` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_COAP` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_DNS_RESOLVER` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_JSON_LIBRARY` \| +--------------------------------------------------+ \| :kconfig:option:`CONFIG_HWINFO` \| +--------------------------------------------------+ * The sensor driver API clarified :c:func:`sensor_trigger_set` to state that the user-allocated sensor trigger will be stored by the driver as a pointer, rather than a copy, and passed back to the handler. This enables the handler to use :c:macro:`CONTAINER_OF` to retrieve a context pointer when the trigger is embedded in a larger struct and requires that the trigger is not allocated on the stack. Applications that allocate a sensor trigger on the stack need to be updated. * Converted few drivers to the :ref:`input` subsystem. * ``gpio_keys``: moved out of ``gpio``, replaced the custom API to use input events instead, the :dtcompatible:`zephyr,gpio-keys` binding is unchanged but now requires ``zephyr,code`` to be set. * ``ft5336``: moved from :ref:`kscan_api` to :ref:`input`, renamed the Kconfig options from ``CONFIG_KSCAN_FT5336``, ``CONFIG_KSCAN_FT5336_PERIOD`` and ``KSCAN_FT5336_INTERRUPT`` to :kconfig:option:`CONFIG_INPUT_FT5336`, :kconfig:option:`CONFIG_INPUT_FT5336_PERIOD` and :kconfig:option:`CONFIG_INPUT_FT5336_INTERRUPT`. * ``kscan_sdl``: moved from :ref:`kscan_api` to :ref:`input`, renamed the Kconfig option from ``KSCAN_SDL`` to :kconfig:option:`CONFIG_INPUT_SDL_TOUCH` and the compatible from ``zephyr,sdl-kscan`` to :dtcompatible:`zephyr,input-sdl-touch`. * ``nuvoton,npcx-kscan`` moved to :ref:`input`, renamed the Kconfig option names from ``KSCAN_NPCX_...`` to ``INPUT_NPCX_KBD...`` and the compatible from ``nuvoton,npcx-kscan`` to :dtcompatible:`nuvoton,npcx-kbd`. * Touchscreen drivers converted to use the input APIs can use the :dtcompatible:`zephyr,kscan-input` driver to maintain Kscan compatibility. * The declaration of :c:func:`main` has been changed from ``void main(void)`` to ``int main(void)``. The main function is required to return the value zero. All other return values are reserved. This aligns Zephyr with the C and C++ language specification requirements for "hosted" environments, avoiding compiler warnings and errors. These compiler messages are generated when applications are built in "hosted" mode (which means without the ``-ffreestanding`` compiler flag). As the ``-ffreestanding`` flag is currently enabled unless the application is using picolibc, only applications using picolibc will be affected by this change at this time. * The following network interface APIs now take additional, ``struct net_if * iface`` parameter: * :c:func:`net_if_ipv4_maddr_join` * :c:func:`net_if_ipv4_maddr_leave` * :c:func:`net_if_ipv6_maddr_join` * :c:func:`net_if_ipv6_maddr_leave` * MCUmgr transports now need to set up the struct before registering it by setting the function pointers to the function handlers, these have been moved to a ``functions`` struct object of type :c:struct:`smp_transport_api_t`. Because of these changes, the legacy transport registration function and object are no longer available. The registration function now returns a value which is 0 for success or a negative error code if an error occurred. * Added a new flag :c:struct:`dac_channel_cfg` ``buffered`` for DAC channels in :c:struct:`dac_channel_cfg` to allow the configuration of the output buffer. The actual interpretation of this depends on the hardware and is so far only implemented for the STM32 DAC driver. Implicitly for this driver this changes the default from being buffered to unbuffered. * MCUmgr fs_mgmt group's file access hook is now called for all fs_mgmt group functions (adding support for file status and file hash/checksum). In addition, if the file access state is not lost, it will now only be called once for the file access instead of each time a command is received. Note that the structure for the notification has changed, the ``upload`` bool has been replaced with an enum to indicate what function is used, see :c:struct:`fs_mgmt_file_access` for the new structure definition. * Iterable sections API is now available at :zephyr_file:`include/zephyr/sys/iterable_sections.h`. LD linker snippets are available at :zephyr_file:`include/zephyr/linker/iterable_sections.h`. * Cache API functions are now fully inlined by compilers. * The Bluetooth HCI headers have been reworked, with ``hci.h`` now containing only the function prototypes and the new ``hci_types.h`` defining all HCI-related macros and structs. The previous ``hci_err.h`` has been merged into ``hci_types.h``. Removed APIs in this release ============================ * Pinmux API has been removed. Pin control needs to be used as its replacement, refer to :ref:`pinctrl-guide` for more details. Deprecated in this release ========================== * Configuring applications with ``prj_<board>.conf`` files has been deprecated, this should be replaced by using a prj.conf with the common configuration and board-specific configuration in board Kconfig fragments in the ``boards`` folder of the application. * On nRF51 and nRF52-based boards, the behavior of the reset reason being provided to :c:func:`sys_reboot` and being set in the GPREGRET register has been dropped. This function will now just reboot the device without changing the register contents. The new method for setting this register uses the boot mode feature of the retention subsystem, see the :ref:`boot mode API <boot_mode_api>` for details. To restore the deprecated functionality, enable :kconfig:option:`CONFIG_NRF_STORE_REBOOT_TYPE_GPREGRET`. * Deprecated :c:macro:`PTHREAD_BARRIER_DEFINE` in favor of the standardized :c:func:`pthread_barrier_init` * On all STM32 targets except STM32F2 series, Ethernet drivers implementation based on STM32Cube Ethernet API V1 (:kconfig:option:`CONFIG_ETH_STM32_HAL_API_V1`) is now deprecated in favor of implementation based on more reliable and performant STM32Cube Ethernet API V2. * Legacy Ztest API was deprecated. All new tests shall use the new Ztest API. Stable API changes in this release ================================== * Removed `bt_set_oob_data_flag` and replaced it with two new API calls: * :c:func:`bt_le_oob_set_sc_flag` for setting/clearing OOB flag in SC pairing * :c:func:`bt_le_oob_set_legacy_flag` for setting/clearing OOB flag in legacy paring * :c:macro:`SYS_INIT` callback no longer requires a :c:struct:`device` argument. The new callback signature is ``int f(void)``. A utility script to automatically migrate existing projects can be found in :zephyr_file:`scripts/utils/migrate_sys_init.py`. * Changed :c:struct:`spi_config` ``cs`` (:c:struct:`spi_cs_control`) from pointer to struct member. This allows using the existing SPI dt-spec macros in C++. SPI controller drivers doing ``NULL`` checks on the ``cs`` field to check if CS is GPIO-based or not, must now use :c:func:`spi_cs_is_gpio` or :c:func:`spi_cs_is_gpio_dt` calls. New APIs in this release ======================== * Introduced :c:func:`flash_ex_op` function. This allows to perform extra operations on flash devices, defined by Zephyr Flash API or by vendor specific header files. Support for extra operations is enabled by :kconfig:option:`CONFIG_FLASH_EX_OP_ENABLED` which depends on :kconfig:option:`CONFIG_FLASH_HAS_EX_OP` selected by driver. * Introduced :ref:`rtc_api` API which adds experimental support for real-time clock devices.

To build for an older revision of the nRF9160 DK without external flash, specify that older board revision when building. * ``nrf9160dk_nrf52840``: Enabled external_flash_pins_routing switch by default. * ``nrf9160dk_nrf9160``: Changed the order of buttons and switches on the GPIO expander to match the order when using GPIO directly on the nRF9160 SoC. * ``STM32H747i_disco``: Enabled support for ST B-LCD40-DSI1 display extension * ``qemu_cortex_m0``: Fixed prescaler of the system timer so that its frequency is actually 1 MHz, not 2 MHz. * Made these changes for ARM64 boards: * FVP revc_2xaemv8a / aemv8r: Added ethernet, PHY and MDIO nodes * Made these changes to POSIX boards: * nrf52_bsim now includes support and models for: * 802.15.4 in the RADIO. * EGU. * FLASH (NVMC & UICR). * TEMP. * UART connected to a host ptty. * Many more minor CMSIS API and nRF APIs and drivers. * Made these changes for RISC-V boards: * ``gd32vf103``: No longer requires special OpenOCD version. * Made these changes for X86 boards: * Made these changes for Xtensa boards: * Removed support for these ARC boards: * Removed support for these ARM boards: * Removed support for these RISC-V boards: * BeagleV Starlight JH7100 * Removed support for these X86 boards: * Removed support for these Xtensa boards: * Made these changes in other boards: * Added support for these following shields: * Adafruit Data Logger Shield * nPM1300 EK (Power Management Integrated Circuit (PMIC)) * Panasonic Grid-EYE Shields * ST B_LCD40_DSI1_MB1166 Build system and infrastructure ******************************* * Fixed an issue whereby older versions of the Zephyr SDK toolchain were used instead of the latest compatible version. * Fixed an issue whereby building an application with sysbuild and specifying mcuboot's verification to be checksum only did not build a bootable image. * Fixed an issue whereby if no prj.conf file was present then board configuration files would not be included by emitting a fatal error. As a result, prj.conf files are now mandatory in projects. * Introduced support for extending/replacing the signing mechanism in zephyr, see :ref:`West extending signing <west-extending-signing>` for further details. * Fixed an issue whereby when using ``_ROOT`` variables with Sysbuild, these were lost for images. Enhanced ``zephyr_get`` CMake helper function to optionally support merging of scoped variables into a list. * Added a new CMake helper function for setting/updating sysbuild CMake cache variables: ``sysbuild_cache_set``. * Enhanced ``zephyr_get`` CMake helper function to lookup multiple variables and return the result in a variable of different name. * Introduced ``EXTRA_CONF_FILE``, ``EXTRA_DTC_OVERLAY_FILE``, and ``EXTRA_ZEPHYR_MODULES`` for better naming consistency and uniform behavior for applying extra build settings in addition to Zephyr automatic build setting lookup. ``EXTRA_CONF_FILE`` replaces ``OVERLAY_CONFIG``. ``EXTRA_ZEPHYR_MODULES`` replaces ``ZEPHYR_EXTRA_MODULES``. ``EXTRA_DTC_OVERLAY_FILE`` is new, see :ref:`Set devicetree overlays <set-devicetree-overlays>` for further details. * Twister now supports ``gtest`` harness for running tests written in gTest. * Added an option to validate device initialization priorities at build time. To use it, enable :kconfig:option:`CONFIG_CHECK_INIT_PRIORITIES`, see :ref:`check_init_priorities.py` for more details. * Added a new option to disable tracking of macro expansion when compiling, :kconfig:option:`CONFIG_COMPILER_TRACK_MACRO_EXPANSION`. This option may be disabled to reduce compiler verbosity when errors occur during macro expansions, e.g. in device definition macros. * Twister now supports loading test configurations from alternative root folder/s by using ``--alt-config-root``. When a test is found, Twister will check if a test configuration file exist in any of the alternative test configuration root folders. For example, given ``$test_root/tests/foo/testcase.yaml``, Twister will use ``$alt_config_root/tests/foo/testcase.yaml`` if it exists. * Twister now uses native YAML lists for fields that were previously defined using space-separated strings. For example: .. code-block:: yaml platform_allow: foo bar can now be written as: .. code-block:: yaml platform_allow: - foo - bar This applies to the following properties: - ``arch_exclude`` - ``arch_allow`` - ``depends_on`` - ``extra_args`` - ``extra_sections`` - ``platform_exclude`` - ``platform_allow`` - ``tags`` - ``toolchain_exclude`` - ``toolchain_allow`` Note that the old behavior is kept as deprecated. The :zephyr_file:`scripts/utils/twister_to_list.py` script can be used to automatically migrate Twister configuration files. * When MCUboot image signing is enabled, a warning will now be emitted by cmake if no signing key is set in the project, this warning can be safely ignored if signing is performed manually or outside of zephyr. This warning informs the user that the generated image will not be bootable by MCUboot as-is. * Babblesim is now included in the west manifest. Users can fetch it by enabling the ``babblesim`` group with west config. * `west sign` now uses DT labels, of "fixed-partition" compatible nodes, to identify application image slots, instead of previously used DT node label properties. If you have been using custom partition layout for MCUboot, you will have to label your MCUboot slot partitions with proper DT node labels; for example partition with "image-0" label property will have to be given slot0_partition DT node label. Label property does not have to be removed from partition node, but will not be used. DT node labels used are listed below .. table:: :align: center +---------------------------------+---------------------------+ \| Partition with label property \| Required DT node label \| +=================================+===========================+ \| "image-0" \| slot0_partition \| +---------------------------------+---------------------------+ \| "image-1" \| slot1_partition \| +---------------------------------+---------------------------+ * Fixed an issue whereby relative paths supplied for the ``BOARD_ROOT`` value might wrongly emit a warning about a ``boards`` directory not being found. * Fixed an issue whereby relative paths did not work for sysbuild images. Drivers and Sensors ******************* * Device model * Devices that do not require an initialization routine can now pass ``NULL`` to the ``DEVICE__DEFINE()`` macros. Auxiliary display * New auxiliary display (auxdisplay) peripheral has been added, this allows for interfacing with simple alphanumeric displays that do not feature graphic capabilities. This peripheral is marked as unstable. * HD44780 driver added. * Noritake Itron driver added. * Grove LCD driver added (ported from existing sample). * ADC * MCUX LPADC driver now uses the channel parameter to select a software channel configuration buffer. Use ``zephyr,input-positive`` and ``zephyr,input-negative`` devicetree properties to select the hardware channel(s) to link a software channel configuration to. * MCUX LPADC driver ``voltage-ref`` and ``power-level`` devicetree properties were shifted to match the hardware as described in reference manual instead of matching the NXP SDK enum identifiers. * Added support for STM32C0 and STM32H5. * Added DMA support for STM32H7. * STM32: Resolutions are now listed in the device tree for each ADC instance * STM32: Sampling times are now listed in the device tree for each ADC instance * Added driver for Atmel SAM family ADC. * Added driver for Gecko Incremental ADC. * Added driver for Infineon CAT1 ADC. * Added driver for TI ADS7052. * Added driver for TI ADS114S0x family. * Added drivers for Renesas SmartBond GPADC and SDADC. * Battery-backed RAM * Added MCP7940N battery-backed RTC SRAM driver. * CAN * The CAN statistics are now reset when calling :c:func:`can_start`. * Renamed the NXP FlexCAN devicetree binding compatible from ``nxp,kinetis-flexcan`` to :dtcompatible:`nxp,flexcan`. * Added support for the CAN-FD variant of the NXP FlexCAN controller using devicetree binding :dtcompatible:`nxp,flexcan-fd`. * Added support for the NXP NXP S32 CANEXCEL controller using devicetree binding :dtcompatible:`nxp,s32-canxl`. * Added support for the Atmel SAM0 CAN controller using devicetree binding :dtcompatible:`atmel,sam0-can`. * Refactored the Bosch M_CAN controller driver backend to allow for per-instance configuration via devicetree. * Now supports STM32H5 series. * Clock control * Atmel SAM/SAM0: Introduced peripheral clock control. * Atmel SAM0: Improved ``samd20``/``samd21``/``samr21`` clocking mechanism. * STM32F4: Added support for PLL I2S * Console: * The native_posix and bsim console drivers have been merged into one generic driver usable by all POSIX arch based boards. * Counter * Added support on timer based counter on STM32H7 and STM32H5 * Added support on RTC based counter on STM32C0 and STM32H5 * Crypto * Added support for STM32H5 AES * DAC * Added support on STM32H5 series. * Disk * SDMMC STM32L4+: Now compatible with internal DMA * NVME disks are now supported using FATFS, with a single I/O queue enabled * Display * Improved MCUX ELCDIF and SSD16XX display controller drivers * Added support for ILI9342C display controller * Added support for OTM8009A panel * DMA * STM32C0: Added support for DMA * STM32H5: Added support for GPDMA * STM32H7: Added support for BDMA * Added DMA support for the RP2040 SoC * EEPROM * Switched from :dtcompatible:`atmel,at24` to dedicated :dtcompatible:`zephyr,i2c-target-eeprom` for I2C EEPROM target driver. * Entropy * Added support for STM32H5 series. * Flash * Introduced new flash API call :c:func:`flash_ex_op` which calls :c:func:`ec_op` callback provided by a flash driver. This allows to perform extra operations on flash devices, defined by Zephyr Flash API or by vendor specific header files. :kconfig:option:`CONFIG_FLASH_HAS_EX_OP` should be selected by the driver to indicate that extra operations are supported. To enable extra operations user should select :kconfig:option:`CONFIG_FLASH_EX_OP_ENABLED`. * STM32F4: Now supports write protection and readout protection through new flash API call :c:func:`flash_ex_op`. * nrf_qspi_nor: Replaced custom API function ``nrf_qspi_nor_base_clock_div_force`` with ``nrf_qspi_nor_xip_enable`` which apart from forcing the clock divider prevents the driver from deactivating the QSPI peripheral so that the XIP operation is actually possible. * flash_simulator: * A memory region can now be used as the storage area for the flash simulator. Using the memory region allows the flash simulator to keep its contents over a device reboot. * When building in native_posix, command line options have been added to select if the flash should be cleared at boot, the flash content kept in RAM, or the flash content file be deleted on exit. * spi_flash_at45: Fixed erase procedure to properly handle chips that have their initial sector split into two parts (usually marked as 0a and 0b). * STM32H5 now supports OSPI * GPIO * Converted the ``gpio_keys`` driver to the input subsystem. * Added single-ended IO support for the RP2040 SoC * STM32: Supports newly introduced experimental API to enable/disable interrupts without re-config * I2C * Added support for STM32C0 and STM32H5 series * I2S * STM32: Domain clock should now be configured by device tree. * Input * Introduced the :ref:`input` subsystem. * KSCAN * Added a :dtcompatible:`zephyr,kscan-input` input to kscan compatibility driver. * Converted the ``ft5336`` and ``kscan_sdl`` drivers to the input subsystem. * MIPI-DSI * Added support on STM32H7 * Misc * Added PIO support for the RP2040 SoC * PCIE * Enable filtering PCIe devices by class/revision. * PECI * Retained memory * Retained memory (retained_mem) driver has been added with backends for Nordic nRF GPREGRET, and uninitialised RAM. * Pin control * Added support for Infineon CAT1 * Added support for TI K3 * Added support for ARC emdsp * PWM * Added support for STM32C0. * STM32: Now supports 6-PWM channels * Added PWM driver for Microchip XEC BBLED. * Power domain * Regulators * The regulator API can now be built without thread-safe reference counting by using :kconfig:option:`CONFIG_REGULATOR_THREAD_SAFE_REFCNT`.

Libraries / Subsystems ********************** * File systems * Added :kconfig:option:`CONFIG_FS_FATFS_REENTRANT` to enable the FAT FS reentrant option. * With LittleFS as backend, :c:func:`fs_mount` return code was corrected to ``EFAULT`` when called with ``FS_MOUNT_FLAG_NO_FORMAT`` and the designated LittleFS area could not be mounted because it has not yet been mounted or it required reformatting. * The FAT FS initialization order has been updated to match LittleFS, fixing an issue where attempting to mount the disk in a global function caused FAT FS to fail due to not being registered beforehand. FAT FS is now initialized in POST_KERNEL. * Added :kconfig:option:`CONFIG_FS_LITTLEFS_FMP_DEV` to enable possibility of using LittleFS for block devices only, e.g. without Flash support. The option is set to 'y' by default in order to keep previous behaviour. * IPC * :c:func:`ipc_service_close_instance` now only acts on bounded endpoints. * ICMSG: removed race condition during bonding. * ICMSG: removed internal API for clearing shared memory. * ICMSG: added mutual exclusion access to SHMEM. * Fixed CONFIG_OPENAMP_WITH_DCACHE. * Management * Added optional input expiration to shell MCUmgr transport, this allows returning the shell to normal operation if a complete MCUmgr packet is not received in a specific duration. Can be enabled with :kconfig:option:`CONFIG_MCUMGR_TRANSPORT_SHELL_INPUT_TIMEOUT` and timeout set with :kconfig:option:`CONFIG_MCUMGR_TRANSPORT_SHELL_INPUT_TIMEOUT_TIME`. * MCUmgr fs_mgmt upload and download now caches the file handle to improve throughput when transferring data, the file is no longer opened and closed for each part of a transfer. In addition, new functionality has been added that will allow closing file handles of uploaded/downloaded files if they are idle for a period of time, the timeout is set with :kconfig:option:`MCUMGR_GRP_FS_FILE_AUTOMATIC_IDLE_CLOSE_TIME`. There is a new command that can be used to close open file handles which can be used after a file upload is complete to ensure that the file handle is closed correctly, allowing other transports or other parts of the application code to use it. * A new version of the SMP protocol used by MCUmgr has been introduced in the header, which is used to indicate the version of the protocol being used. This updated protocol allows returning much more detailed error responses per group, see the :ref:`MCUmgr SMP protocol specification <mcumgr_smp_protocol_specification>` for details. * MCUmgr has now been marked as a stable Zephyr API. * The MCUmgr UDP transport has been refactored to resolve some concurrency issues and fixes a potential issue whereby an application might call the open transport function whilst it is already open, causing an endless log output loop. * The MCUmgr fs_mgmt group Kconfig ``Insecure`` text has been replaced with a CMake warning which triggers if fs_mgmt hooks are not enabled, as these hooks can be used to ensure security of file access allowed by MCUmgr clients. * Fixed an issue with MCUmgr fs_mgmt file download not checking if the offset parameter was provided. * Fixed an issue with MCUmgr fs_mgmt file upload notification hook not setting upload to true. * Fixed an issue with MCUmgr img_mgmt image upload ``upgrade`` field wrongly checking if the new image was the same version of the application and allowing it to be uploaded if it was. * MCUmgr img_mgmt group will only verify the SHA256 hash provided by the client against the uploaded image (if support is enabled) if a full SHA256 hash was provided. * MCUmgr Kconfig options have changed from ``select`` to ``depends on`` which means that some additional Kconfig options may now need to be selected by applications. :kconfig:option:`CONFIG_NET_BUF`, :kconfig:option:`CONFIG_ZCBOR` and :kconfig:option:`CONFIG_CRC` are needed to enable MCUmgr support, :kconfig:option:`CONFIG_BASE64` is needed to enable shell/UART/dummy MCUmgr transports, :kconfig:option:`CONFIG_NET_SOCKETS` is needed to enable the UDP MCUmgr transport, :kconfig:option:`CONFIG_FLASH` is needed to enable MCUmgr fs_mgmt, :kconfig:option:`CONFIG_FLASH` and :kconfig:option:`CONFIG_IMG_MANAGER` are needed to enable MCUmgr img_mgmt. * MCUmgr img_mgmt group now uses unsigned integer values for image and slot numbers, these numbers would never have been negative and should have been unsigned. * POSIX API * Improved the locking strategy for :c:func:`eventfd_read()` and :c:func:`eventfd_write()`. This eliminated a deadlock scenario that was present since the initial contribution and increased performance by a factor of 10x. * Reimplemented :ref:`POSIX <posix_support>` threads, mutexes, condition variables, and barriers using native Zephyr counterparts. POSIX synchronization primitives in Zephyr were originally implemented separately and received less maintenance as a result. Unfortunately, this opened POSIX up to unique bugs and race conditions. Going forward, POSIX will benefit from all improvements to Zephyr's synchronization and threading API and race conditions have been mitigated. * Retention * Retention subsystem has been added which adds enhanced features over retained memory drivers allowing for partitioning, magic headers and checksum validation. See :ref:`retention API <retention_api>` for details. Support for the retention subsystem is experimental. * Boot mode retention module has been added which allows for setting/checking the boot mode of an application, initial support has also been added to MCUboot to allow for applications to use this as an entrance method for MCUboot serial recovery mode. See :ref:`boot mode API <boot_mode_api>` for details. * RTIO * Added policy that every ``sqe`` will generate a ``cqe`` (previously an RTIO_SQE_TRANSACTION entry would only trigger a ``cqe`` on the last ``sqe`` in the transaction. * Power management * Added a new policy event API that can be used to register expected events that will wake the system up in the future. This can be used to influence the system on which low power states can be used. * Added a new device tree property ``zephyr,pm-device-runtime-auto`` to automatically enable device runtime power management on a device after its initialization. HALs **** * Nordic * Updated nrfx to version 3.0.0. * STM32 * stm32cube: updated STM32F0 to cube version V1.11.4. * stm32cube: updated STM32F3 to cube version V1.11.4 * stm32cube: updated STM32L0 to cube version V1.12.2 * stm32cube: updated STM32U5 to cube version V1.2.0 * stm32cube: updated STM32WB to cube version V1.16.0 * Raspberry Pi Pico * Updated hal_rpi_pico to version 1.5.0 MCUboot ******* * Relocated the MCUboot Kconfig options from the main ``Kconfig.zephyr`` file to a new ``modules/Kconfig.mcuboot`` module-specific file. This means that, for interactive Kconfig interfaces, the MCUboot options will now be located under ``Modules`` instead of under ``Boot Options``. * Added :kconfig:option:`CONFIG_MCUBOOT_CMAKE_WEST_SIGN_PARAMS` that allows to pass arguments to west sign when invoked from cmake. Storage ******* * Added :kconfig:option:`CONFIG_FLASH_MAP_LABELS`, which will enable runtime access to the labels property of fixed partitions. This option is implied if kconfig:option:`CONFIG_FLASH_MAP_SHELL` is enabled. These labels will be displayed in a separate column when using the ``flash_map list`` shell command. Trusted Firmware-M ****************** * Enable routing of PSA Crypto API calls from NS to S, thanks to separating MbedTLS into three distinct libraries at build time (crypto, TLS, X.509). This also resolves header conflicts with earlier integrations of TF-M and MbedTLS. * Added psa_crypto sample back. zcbor ***** Updated from 0.6.0 to 0.7.0. Among other things, this update brings: * C++ improvements * float16 support * Improved docs * -Wall and -Wconversion compliance Tests and Samples ***************** * Two Babblesim based networking (802.15.4) tests have been added, which are run in Zephyr's CI system. One of them including the OpenThread stack. * For native_posix and the nrf52_bsim: Many tests have been fixed and enabled. * LittleFS sample has been given SPI example configuration for nrf52840dk_nrf52840. * Migrated all tests to new Ztest API and deprecated legacy Ztest. ```	/content/code_sandbox/doc/releases/release-notes-3.4.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	13,980
```restructuredtext :orphan: .. _zephyr_3.1: Zephyr 3.1.0 ############ The following sections provide detailed lists of changes by component. API Changes *********** Changes in this release ======================= * All Zephyr public headers have been moved to ``include/zephyr``, meaning they need to be prefixed with ``<zephyr/...>`` when included. Because this change can potentially break many applications or libraries, :kconfig:option:`CONFIG_LEGACY_INCLUDE_PATH` is provided to allow using the old include path. This option is now enabled by default to allow a smooth transition. In order to facilitate the migration to the new include prefix, a script to automate the process is also provided: :zephyr_file:`scripts/utils/migrate_includes.py`. * LoRaWAN: The message type parameter in :c:func:`lorawan_send` was changed from ``uint8_t`` to ``enum lorawan_message_type``. If ``0`` was passed for unconfirmed message, this has to be changed to ``LORAWAN_MSG_UNCONFIRMED``. * Bluetooth: Applications where :kconfig:option:`CONFIG_BT_EATT` is enabled must set the :c:member:`chan_opt` field on the GATT parameter structs. To keep the old behavior use :c:enumerator:`BT_ATT_CHAN_OPT_NONE`. * Disk Subsystem: SPI mode SD cards now use the SD subsystem to communicate with SD cards. See :ref:`the disk access api <disk_access_api>` for an example of the new devicetree binding format required. * Kconfig preprocessor function ``dt_nodelabel_has_compat`` was redefined, for consistency with the ``dt_nodelabel_has_prop`` function and devicetree macros like :c:func:`DT_NODE_HAS_COMPAT`. Now the function does not take into account the status of the checked node. Its former functionality is provided by the newly introduced ``dt_nodelabel_enabled_with_compat`` function. * CAN * Added ``const struct device`` parameter to the following CAN callback function signatures: * ``can_tx_callback_t`` * ``can_rx_callback_t`` * ``can_state_change_callback_t`` * Allow calling the following CAN API functions from userspace: * :c:func:`can_set_mode()` * :c:func:`can_calc_timing()` * :c:func:`can_calc_timing_data()` * :c:func:`can_set_bitrate()` * :c:func:`can_get_max_filters()` * Changed :c:func:`can_set_bitrate()` to use a sample point of 75.0% for bitrates over 800 kbit/s, 80.0% for bitrates over 500 kbit/s, and 87.5% for all other bitrates. * Split CAN classic and CAN-FD APIs: * :c:func:`can_set_timing()` split into :c:func:`can_set_timing()` and :c:func:`can_set_timing_data()`. * :c:func:`can_set_bitrate()` split into :c:func:`can_set_bitrate()` and :c:func:`can_set_bitrate_data()`. * Converted the ``enum can_mode`` into a ``can_mode_t`` bitfield and renamed the CAN mode definitions: * ``CAN_NORMAL_MODE`` renamed to :c:macro:`CAN_MODE_NORMAL`. * ``CAN_SILENT_MODE`` renamed to :c:macro:`CAN_MODE_LISTENONLY`. * ``CAN_LOOPBACK_MODE`` renamed to :c:macro:`CAN_MODE_LOOPBACK`. * The previous ``CAN_SILENT_LOOPBACK_MODE`` can be set using the bitmask ``(CAN_MODE_LISTENONLY \| CAN_MODE_LOOPBACK)``. * STM32H7: :kconfig:option:`CONFIG_NOCACHE_MEMORY` is no longer responsible for disabling data cache when defined. Use ``CONFIG_DCACHE=n`` instead. * Converted the STM32F1 pin nodes configuration names to include remap information (in cases other than NO_REMAP/REMAP_0) For instance: * ``i2c1_scl_pb8`` renamed to ``i2c1_scl_remap1_pb8`` Removed APIs in this release ============================ * STM32F1 Serial wire JTAG configuration (SWJ CFG) configuration choice was moved from Kconfig to :ref:`devicetree <dt-guide>`. See the :dtcompatible:`st,stm32f1-pinctrl` devicetree binding for more information. As a consequence, the following Kconfig symbols were removed: * ``CONFIG_GPIO_STM32_SWJ_ENABLE`` * ``CONFIG_GPIO_STM32_SWJ_NONJTRST`` * ``CONFIG_GPIO_STM32_SWJ_NOJTAG`` * ``CONFIG_GPIO_STM32_SWJ_DISABLE`` * Removed experimental 6LoCAN protocol support. * Removed the following deprecated CAN APIs: * Custom CAN error codes * ``can_configure()`` * ``can_attach_workq()`` * ``can_attach_isr()`` * ``can_attach_msgq()`` * ``can_detach()`` * ``can_register_state_change_isr()`` * ``can_write()`` Deprecated in this release ========================== * :c:func:`nvs_init` is deprecated in favor of utilizing :c:func:`nvs_mount`. * :c:func:`lwm2m_engine_set_res_data` is deprecated in favor of :c:func:`lwm2m_engine_set_res_buf` * :c:func:`lwm2m_engine_get_res_data` is deprecated in favor of :c:func:`lwm2m_engine_get_res_buf` * The TinyCBOR module has been deprecated in favor of the new zcbor CBOR library, included with Zephyr in this release. * GPIO * Deprecated the ``GPIO_INT_DEBOUNCE`` flag and the ``GPIO_DS_`` and ``GPIO_VOLTAGE_`` groups of flags. Controller/SoC specific flags should now be used instead. * SPI * Deprecated the ``gpio_dev``, ``gpio_pin``, and ``gpio_dt_flags`` members in struct :c:struct:`spi_cs_control` in favor of a new struct :c:struct:`gpio_dt_spec` member named ``gpio``. * PWM * The ``pin`` prefix has been removed from all PWM API calls. So for example, ``pwm_pin_set_cycles`` is now ``pwm_set_cycles``. The old API calls are still provided, but are now deprecated. * PWM periods are now always set in nanoseconds, so ``_nsec`` and ``_usec`` set functions such as ``pwm_pin_set_nsec()`` and ``pwm_pin_set_usec()`` have been deprecated. Other units can be specified using, e.g. ``PWM_USEC()`` macros, which convert other units to nanoseconds. * Utilities * :c:macro:`UTIL_LISTIFY` has been deprecated. Use :c:macro:`LISTIFY` instead. * Mesh * The following functions related to the Bluetooth Mesh Health Client model: * :c:func:`bt_mesh_health_fault_get()` replace with :c:func:`bt_mesh_health_cli_fault_get()` * :c:func:`bt_mesh_health_fault_clear()` replace with :c:func:`bt_mesh_health_cli_fault_clear()` * :c:func:`bt_mesh_health_fault_clear_unack()` replace with :c:func:`bt_mesh_health_cli_fault_clear_unack()` * :c:func:`bt_mesh_health_fault_test()` replace with :c:func:`bt_mesh_health_cli_fault_test()` * :c:func:`bt_mesh_health_fault_test_unack()` replace with :c:func:`bt_mesh_health_cli_fault_test_unack()` * :c:func:`bt_mesh_health_period_get()` replace with :c:func:`bt_mesh_health_cli_period_get()` * :c:func:`bt_mesh_health_period_set()` replace with :c:func:`bt_mesh_health_cli_period_set()` * :c:func:`bt_mesh_health_period_set_unack()` replace with :c:func:`bt_mesh_health_cli_period_set_unack()` * :c:func:`bt_mesh_health_attention_get()` replace with :c:func:`bt_mesh_health_cli_attention_get()` * :c:func:`bt_mesh_health_attention_set()` replace with :c:func:`bt_mesh_health_cli_attention_set()` * :c:func:`bt_mesh_health_attention_set_unack()` replace with :c:func:`bt_mesh_health_cli_attention_set_unack()` * The following function related to the Bluetooth Mesh Health Server model: * :c:func:`bt_mesh_fault_update()` replace with :c:func:`bt_mesh_health_srv_fault_update()` Stable API changes in this release ================================== New APIs in this release ======================== * Util * Added :c:macro:`IN_RANGE` for checking if a value is in the range of two other values. * SDHC API * Added the :ref:`SDHC api <sdhc_api>`, used to interact with SD host controllers. * MIPI-DSI * Added a :ref:`MIPI-DSI api <mipi_dsi_api>`. This is an experimental API, some of the features/APIs will be implemented later. * CAN * Added support for getting the minimum/maximum supported CAN timing parameters: * :c:func:`can_get_timing_min()` * :c:func:`can_get_timing_max()` * :c:func:`can_get_timing_data_min()` * :c:func:`can_get_timing_data_max()` * Added support for enabling/disabling CAN-FD mode at runtime using :c:macro:`CAN_MODE_FD`. Bluetooth ********* * Extended and Periodic advertising are no longer experimental * Direction Finding is no longer experimental * Added support for disabling Bluetooth, including a new ``bt_disable()`` API call * Audio * Changed the implementation of PACS to indicate instead of notifying * Added support for the Broadcast Audio Scan Service (BASS) * Added support for the Hearing Access Service (HAS) * Added support for the Telephone Bearer Service (TBS) * Direction Finding * Added sampling and switching offset configuration * Mesh * Added support for Proxy Client * Added support for Provisioners over PB-GATT * Added a new heartbeat publication callback option * Controller * Added support for the full ISO TX data path, including ISOAL * Added support for ISO Broadcast Channel Map Update * Added support for ISO Synchronized Receiver Channel Map Update * The new implementation of LL Control Procedures is now the default whenever Direction Finding is enabled * Added support for all missing v3 and v4 DTM commands * Implemented ISO-AL TX unframed fragmentation * Added support for back-to-back receiving of PDUs on nRF5x platforms * Increased the maximum number of simultaneous connections to 250 * HCI Driver * Added support for a new optional :c:member:`bt_hci_driver.close` API which closes HCI transport. * Implemented :c:member:`bt_hci_driver.close` on stm32wb HCI driver. * Host * The :c:enum:`bt_l2cap_chan_state` values ``BT_L2CAP_CONNECT`` and ``BT_L2CAP_DISCONNECT`` have been renamed to ``BT_L2CAP_CONNECTING`` and ``BT_L2CAP_DISCONNECTING`` respectively. * The callbacks :c:func:`pairing_complete`, :c:func:`pairing_failed`, and :c:func:`bond_delete` have been moved from struct :c:struct:`bt_auth_cb` to a newly created informational-only callback struct :c:struct:`bt_conn_auth_info_cb`. * :c:func:`bt_conn_index` now takes a ``const struct bt_conn`` argument. The :c:struct:`bt_gatt_subscribe_params` structure's ``write`` callback function has been deprecated. Use the new ``subscribe`` callback instead. * :c:func:`bt_disable` was added to enable the caller to disable the Bluetooth stack. * Added new Kconfig options to select ISO Central and Peripheral role support separately * Added a new :c:func:`bt_get_appearance()` API call * Implemented support for dynamic appearance, including a new :c:func:`bt_set_appearance()` API call * Implemented support for L2CAP collision mitigation * Changed the scheduling of auto-initiated HCI commands so that they execute synchronously * Added a new :c:func:`bt_is_ready()` API call to find out if Bluetooth is currently enabled and initialized * Added support for automatic MTU exchange right after a connection is established * Created a new :c:struct:`bt_conn_auth_info_cb` to group the security-related callbacks under a single struct * Optimized the memory usage of the Object Transfer Service * Added a new :c:func:`bt_hci_le_rand()` API call to obtain a random number from the LE Controller * Added a new public API to connect EATT channels, :c:func:`bt_eatt_connect()` * Optimized L2CAP channels resource usage when not using dynamic channels * Added the ability to run the Bluetooth RX context from a workqueue, in order to optimize RAM usage. See :kconfig:option:`CONFIG_BT_RECV_CONTEXT`. * Added support for TX complete callback on EATT channels * Corrected the calling of the MTU callback to happen on any reconfiguration Kernel ****** * Aborting an essential thread now causes a kernel panic, as the documentation has always promised but the kernel has never implemented. * The k_timer handler can now correct itself for lost time due to very late-arriving interrupts. * SMP interprocessor interrupts are deferred so that they are sent only at schedule points, and not synchronously when the scheduler state changes. This prevents IPI "storms" with code that does many scheduler operations at once (e.g. waking up a bunch of threads). * The timeslicing API now allows slice times to be controlled independently for each thread, and provides a callback to the app when a thread timeslice has expired. The intent is that this will allow apps the tools to implement CPU resource control algorithms (e.g. fairness or interactivity metrics, budget tracking) that are out of scope for Zephyr's deterministic RTOS scheduler. Architectures ************* * ARC * Added ARCv3 32 bit (HS5x) support - both GNU and MWDT toolchains, both UP and SMP * Worked around debug_select interference with MDB debugger * Switched to hs6x mcpu usage (GNU toolchain) for HS6x * ARM * AARCH32 * Added Cortex-R floating point support * AARCH64 * Added support for GICv3 for the ARMv8 Xen Virtual Machine * Fixed SMP boot code to take into account multiple cores booting at the same time * Added more memory mapping types for device memory * Simplified and optimize switching and user mode transition code * Added support for CONFIG_IRQ_OFFLOAD_NESTED * Fixed booting issue with FVP V8R >= 11.16.16 * Switched to the IRQ stack during ISR execution * Xtensa * Optimized context switches when KERNEL_COHERENCE is enabled to avoid needless stack invalidations for threads that have not migrated between CPUs. * Fixed a bug that could return directly into a thread context from a nested interrupt instead of properly returning to the preempted ISR. * x64_64 * UEFI devices can now use the firmware-initialized system console API as a printk/logging backend, simplifying platform bringup on devices without known-working serial port configurations. Boards & SoC Support ******************** * Added support for these SoC series: * STM32H725/STM32H730/STM32H73B SoC variants * Made these changes in other SoC series: * Added Atmel SAM UPLL clock support * Raspberry Pi Pico: Added HWINFO support * Raspberry Pi Pico: Added I2C support * Raspberry Pi Pico: Added reset controller support * Raspberry Pi Pico: Added USB support * Changes for ARC boards: * Added nsim_hs5x and nsim_hs5x_smp boards with ARCv3 32bit HS5x CPU * Added MWDT toolchain support for nsim_hs6x and nsim_hs6x_smp * Overhauled memory layout for nSIM boards. Added a mechanism to switch between ICCM/DCCM memory layout and flat memory layout (i.e DDR). * Did required platform setup so nsim_hs5x, nsim_hs5x_smp, nsim_hs6x, nsim_hs6x_smp can be run on real HW (HAPS FPGA) with minimum additional configuration * Enabled MWDT toolchain support for hsdk_2cores board * Adjusted test duration for SMP nSIM boards with timeout_multiplier * Added support for these ARM boards: * b_g474e_dpow1 * stm32f401_mini * Added support for these ARM64 boards: * NXP i.MX8MP EVK (i.MX8M Plus LPDDR4 EVK board) * NXP i.MX8MM EVK (i.MX8M Mini LPDDR4 EVK board) * Added support for these RISC-V boards: * GigaDevice GD32VF103C-EVAL * Made these changes in other boards: * sam4s_xplained: Added support for HWINFO * sam_e70_xlained: Added support for HWINFO and CAN-FD * sam_v71_xult: Added support for HWINFO and CAN-FD * gd32e103v_eval: Added prescaler to timer * longan_nano: Added support for TF-Card slot * Added support for these following shields: * Keyestudio CAN-BUS Shield (KS0411) * MikroElektronika WIFI and BLE Shield * X-NUCLEO-53L0A1 ranging and gesture detection sensor expansion board Drivers and Sensors ******************* * ADC * Atmel SAM0: Fixed adc voltage reference * STM32: Added support for :c:enumerator:`adc_reference.ADC_REF_INTERNAL`. * Added the :c:struct:`adc_dt_spec` structure and associated helper macros, e.g. :c:macro:`ADC_DT_SPEC_GET`, to facilitate getting configuration of ADC channels from devicetree nodes. * CAN * Switched from transmitting CAN frames in FIFO/chronological order to transmitting according to CAN-ID priority (NXP FlexCAN, ST STM32 bxCAN, Bosch M_CAN, Microchip MCP2515). * Added support for ST STM32U5 to the ST STM32 FDCAN driver. * Renamed the base Bosch M_CAN devicetree binding compatible from ``bosch,m-can-base`` to :dtcompatible:`bosch,m_can-base`. * Added CAN controller statistics support (NXP FlexCAN, Renesas R-Car, ST STM32 bxCAN). * Added CAN transceiver support. * Added generic SocketCAN network interface and removed driver-specific implementations. * Clock_control * STM32: Driver was cleaned up and overhauled for easier maintenance with a deeper integration of device tree inputs. Driver now takes into account individual activation of clock sources (High/Medium/Low Internal/external speed clocks, PLLs, ...) * STM32: Additionally to above change it is now possible for clock consumers to select an alternate source clock (Eg: LSE) by adding it to its 'clocks' property and then configure it using new clock_control_configure() API. See :dtcompatible:`st,stm32-rcc`, :dtcompatible:`st,stm32h7-rcc` and :dtcompatible:`st,stm32u5-rcc` for more information. * Counter * Added driver for NXP QTMR. * DAC * Added support for STM32F1 SoCs to the STM32 DAC driver. * Disk * Added a generic SDMMC disk driver, that uses the SD subsystem to interact with disk devices. This disk driver will be used with any disk device declared with the ``zephyr,sdmmc-disk`` compatible string. * Display * STM32: Added basic support for LTDC driver. Currently supported on F4, F7, H7, L4+ and MP1 series. * DMA * Added a scatter gather test for DMAs that support it * Cleanly shared Synopsis DW-DMA driver and Intel cAVS GPDMA driver code. * Added support for Synposis DW-DMA transfer lists. * Added support for Intel HDA for audio device and host streams. * Fixes for NXP eDMA to pass scatter gather tests * Entropy * STM32: Prevented the core from entering stop modes during entropy operations. * Ethernet * eth_native_posix: Added support for setting MAC address. * eth_stm32_hal: Fixed a bug which caused a segfault in case of a failed RX buffer allocation. * eth_mcux: Added support for resetting PHY. * eth_liteeth: Refactored driver to use LiteX HAL. * eth_w5500: Fixed possible deadlock due to incorrect IRQ processing. * Flash * Added STM32 OCTOSPI driver. Initial support is provided for L5 and U5 series. Interrupt driven mode. Supports 1 and 8 lines in Single or Dual Transfer Modes. * STM32L5: Added support for Single Bank. * STM32 QSPI driver was extended with QER (SFDP, DTS), custom quad write opcode and 1-1-4 read mode. * Added support for STM32U5 series. * GPIO * Refactored GPIO devicetree flags. The upper 8 bits of ``gpio_dt_flags_t`` are now reserved for controller/SoC specific flags. Certain hardware-specific flags previously defined as common configuration (IO voltage level, drive strength, and debounce filter) were replaced with ones defined in this controller/SoC specific space. * Added Xilinx PS MIO/EMIO GPIO controller driver. * Extended the NXP PCA95XX driver to support also PCAL95XX. * HWINFO * Atmel SAM: Added RSTC support * Raspberry Pi Pico: Added Unique ID and reset cause driver * I2C * Added arbitrary I2C clock speed support with :c:macro:`I2C_SPEED_DT` * NXP flexcomm now supports target (slave) mode * Fixed Atmel SAM/SAM0 exclusive bus access * Added ITE support * I2S * Ported I2S drivers to pinctrl. * Fixed multiple bugs in the NXP I2S (SAI) driver, including problems with DMA transmission and FIFO under/overruns. * MEMC * STM32: Extended FMC driver to support NOR/PSRAM. See :dtcompatible:`st,stm32-fmc-nor-psram.yaml`. * Pin control * Platform support was added for: * Atmel SAM/SAM0 * Espressif ESP32 * ITE IT8XXX2 * Microchip XEC * Nordic nRF (completed support) * Nuvoton NPCX Embedded Controller (EC) * NXP iMX * NXP Kinetis * NXP LPC * RV32M1 * SiFive Freedom * Telink B91 * TI CC13XX/CC26XX * STM32: It is now possible to configure plain GPIO pins using the pinctrl API. See :dtcompatible:`st,stm32-pinctrl` and :dtcompatible:`st,stm32f1-pinctrl` for more information. * PWM * Added :c:struct:`pwm_dt_spec` and associated helpers, e.g. :c:macro:`PWM_DT_SPEC_GET` or :c:func:`pwm_set_dt`. This addition makes it easier to use the PWM API when the PWM channel, period and flags are taken from a devicetree PWM cell. * STM32: Enabled complementary output for timer channel. A PWM consumer can now use :c:macro:`PWM_STM32_COMPLEMENTARY` to specify that PWM output should happen on a complementary channel pincfg (eg:``tim1_ch2n_pb14``). * STM32: Added counter mode support. See :dtcompatible:`st,stm32-timers`. * Aligned nRF PWM drivers (pwm_nrfx and pwm_nrf5_sw) with the updated PWM API. In particular, this means that the :c:func:`pwm_set` and :c:func:`pwm_set_cycles` functions need to be called with a PWM channel as a parameter, not with a pin number like it was for the deprecated ``pwm_pin_set_`` functions. Also, the ``flags`` parameter is now supported by the drivers, so either the :c:macro:`PWM_POLARITY_INVERTED` or :c:macro:`PWM_POLARITY_NORMAL` flag must be provided in each call. Reset * Added reset controller driver API. * Raspberry Pi Pico: Added reset controller driver * Sensor * Added NCPX ADC comparator driver. * Enhanced the BME680 driver to support SPI. * Enhanced the LIS2DW12 driver to support additional filtering and interrupt modes. * Added ICM42670 6-axis accelerometer driver. * Enhanced the VL53L0X driver to support reprogramming its I2C address. * Enhanced the Microchip XEC TACH driver to support pin control and MEC172x. * Added ITE IT8XXX2 voltage comparator driver. * Fixed register definitions in the LSM6DSL driver. * Fixed argument passing bug in the ICM42605 driver. * Removed redundant DEV_NAME helpers in various drivers. * Enhanced the LIS2DH driver to support device power management. * Fixed overflow issue in sensor_value_from_double(). * Added MAX31875 temperature sensor driver. * Serial * STM32: Added tx/rx pin swap and rx invert / tx invert capabilities. * SPI * Ported all SPI drivers to pinctrl * Added support for SPI on the GD32 family * Timer * Ported timer drivers to use pinctrl * LiteX: Ported the timer driver to use the HAL * USB * Added RP2040 (Raspberry Pi Pico) USB device controller driver Networking ********** * CoAP: * Changed :c:struct:`coap_pending` allocation criteria. This now uses a data pointer instead of a timestamp, which does not give a 100% guarantee that structure is not in use already. * Ethernet: * Added a :kconfig:option:`CONFIG_NET_ETHERNET_FORWARD_UNRECOGNISED_ETHERTYPE` option, which allows to forward frames with unrecognised EtherType to the network stack. * HTTP: * Removed a limitation where the maximum content length was limited up to 100000 bytes. * Fixed ``http_client_req()`` return value. The function now correctly reports the number of bytes sent. * Clarified the expected behavior in case of empty response from the server. * Made use of ``shutdown`` to tear down HTTP connection instead of closing the socket from a system work queue. * LwM2M: * Various improvements towards LwM2M 1.1 support: * Added LwM2M 1.1 Discovery support. * Added attribute handling for Resource Instances. * Added support for Send, Read-composite, Write-composite, Observe-composite operations. * Added new content formats: SenML JSON, CBOR, SenML CBOR. * Added v1.1 implementation of core LwM2M objects. * Added support for dynamic Resource Instance allocation. * Added support for LwM2M Portfolio object (Object ID 16). * Added LwM2M shell module. * Added option to utilize DTLS session cache in queue mode. * Added :c:func:`lwm2m_engine_path_is_observed` API function. * Fixed a bug with hostname verification setting, which prevented DTLS connection in certain mbedTLS configurations. * Fixed a bug which could cause a socket descriptor leak, in case :c:func:`lwm2m_rd_client_start` was called immediately after :c:func:`lwm2m_rd_client_stop`. * Added error reporting from :c:func:`lwm2m_rd_client_start` and :c:func:`lwm2m_rd_client_stop`. * Misc: * Added :c:func:`net_if_set_default` function which allows to set a default network interface at runtime. * Added :kconfig:option:`CONFIG_NET_DEFAULT_IF_UP` option which allows to make the first interface which is up the default choice. * Fixed packet leak in network shell TCP receive handler. * Added :c:func:`net_pkt_rx_clone` which allows to allocated packet from correct packet pool when cloning. This is used at the loopback interface. * Added :kconfig:option:`CONFIG_NET_LOOPBACK_SIMULATE_PACKET_DROP` option which allows to simulate packet drop at the loopback interface. This is used by certain test cases. * MQTT: * Removed custom logging macros from MQTT implementation, in favour of the common networking logging. * OpenThread: * Updated OpenThread revision up to commit ``130afd9bb6d02f2a07e86b824fb7a79e9fca5fe0``. * Implemented ``otPlatCryptoRand`` platform API for OpenThread. * Added support for PSA MAC keys. * Multiple minor fixes/improvements to align with upstream OpenThread changes. * Sockets: * Added support for ``shutdown()`` function. * Fixed ``sendmsg()`` operation when TCP reported full transmission window. * Added support for ``getpeername()`` function. * Fixed userspace ``accept()`` argument validation. * Added support for :c:macro:`SO_SNDBUF` and :c:macro:`SO_RCVBUF` socket options. * Implemented ``POLLOUT`` reporting from ``poll()`` for STREAM sockets. * Implemented socket dispatcher for offloaded sockets. This module allows to use multiple offloaded socket implementations at the same time. * Introduced a common socket priority for offloaded sockets (:kconfig:option:`CONFIG_NET_SOCKETS_OFFLOAD_PRIORITY`). * Moved socket offloading out of experimental. * TCP: * Implemented receive window handling. * Implemented zero-window probe processing and sending. * Improved TCP stack throughput over loopback interface. * Fixed possible transmission window overflow in case of TCP retransmissions. This could led to TX buffer starvation when TCP entered retransmission mode. * Updated ``FIN_TIMEOUT`` delay to correctly reflect time needed for all FIN packet retransmissions. * Added proper error reporting from TCP to upper layers. This solves the problem of connection errors being reported to the application as graceful connection shutdown. * Added a mechanism which allows upper layers to monitor the TCP transmission window availability. This allows to improve throughput greatly in low-buffer scenarios. * TLS: * Added :c:macro:`TLS_SESSION_CACHE` and :c:macro:`TLS_SESSION_CACHE_PURGE` socket options which allow to control session caching on a socket. * Fixed :c:macro:`TLS_CIPHERSUITE_LIST` socket option, which did not set the cipher list on a socket correctly. USB *** * Moved USB device stack code to own directory in preparation for upcoming rework of USB support. Build System ************ * The build system's internals have been completely overhauled for increased modularity. This makes it easier to reuse individual components through the Zephyr CMake package mechanism. With the improved Zephyr CMake package, the following examples are now possible: * ``find_package(Zephyr)``: load a standard build system, as before * ``find_package(Zephyr COMPONENTS unittest)``: load a specific unittest build component * ``find_package(Zephyr COMPONENTS dts)``: only load the dts module and its direct dependencies * ``find_package(Zephyr COMPONENTS extensions west zephyr_module)``: load multiple specific modules and their dependencies Some use cases that this work intends to enable are: * The sysbuild proposal: `Zephyr sysbuild / multi image #40555 <path_to_url`_ * Running Zephyr CMake configure stages individually. One example is only processing the devicetree steps of the build system, while skipping the rest. This is a required feature for extending twister to do test case filtering based on the devicetree contents without invoking a complete CMake configuration. For more details, see :zephyr_file:`cmake/package_helper.cmake`. * A new Zephyr SDK has been created which now supports macOS and Windows in addition to Linux platforms. For more information, see: path_to_url Devicetree ********** * API * New macros for creating tokens in C from strings in the devicetree: :c:macro:`DT_STRING_UPPER_TOKEN_OR`, :c:macro:`DT_INST_STRING_TOKEN`, :c:macro:`DT_INST_STRING_UPPER_TOKEN`, :c:macro:`DT_INST_STRING_UPPER_TOKEN_OR` * :ref:`devicetree-can-api`: new * Bindings * Several new bindings were created to support :ref:`Pin Control <pinctrl-guide>` driver API implementations. This also affected many peripheral bindings, which now support ``pinctrl-0``, ``pinctrl-1``, ..., and ``pinctrl-names`` properties used to configure peripheral pin assignments in different system states, such as active and low-power states. In some cases, this resulted in the removal of old bindings, or other backwards incompatible changes affecting users of the old bindings. These changes include: * :dtcompatible:`atmel,sam-pinctrl` and :dtcompatible:`atmel,sam0-pinctrl` have been adapted to the new pinctrl bindings interface * :dtcompatible:`espressif,esp32-pinctrl` has replaced ``espressif,esp32-pinmux`` * :dtcompatible:`ite,it8xxx2-pinctrl` and :dtcompatible:`ite,it8xxx2-pinctrl-func` have replaced ``ite,it8xxx2-pinmux`` and ``ite,it8xxx2-pinctrl-conf`` * :dtcompatible:`microchip,xec-pinctrl`: new * :dtcompatible:`nuvoton,npcx-pinctrl`: new * :dtcompatible:`nxp,kinetis-pinctrl` has replaced the ``nxp,kinetis-port-pins`` property found in the ``nxp,kinetis-pinmux`` binding. * :dtcompatible:`nxp,mcux-rt-pinctrl`, :dtcompatible:`nxp,mcux-rt11xx-pinctrl`, :dtcompatible:`nxp,lpc-iocon-pinctrl`, :dtcompatible:`nxp,rt-iocon-pinctrl`, :dtcompatible:`nxp,lpc11u6x-pinctrl`, :dtcompatible:`nxp,imx7d-pinctrl`, :dtcompatible:`nxp,imx8m-pinctrl`, :dtcompatible:`nxp,imx8mp-pinctrl` and :dtcompatible:`nxp,imx-iomuxc`: new * :dtcompatible:`openisa,rv32m1-pinctrl`: new * :dtcompatible:`sifive,pinctrl` has replaced ``sifive,iof`` * :dtcompatible:`telink,b91-pinctrl` has replaced ``telink,b91-pinmux`` * :dtcompatible:`ti,cc13xx-cc26xx-pinctrl` has replaced ``ti,cc13xx-cc26xx-pinmux`` * PWM bindings now generally have ``#pwm-cells`` set to 3, not 2 as it was in previous releases. This was done to follow the Linux convention that each PWM specifier should contain a channel, period, and flags cell, in that order. See pull request `#44523 <path_to_url`_ for more details on this change and its purpose. * Some bindings had their :ref:`compatible properties <dt-important-props>` renamed: * :dtcompatible:`nxp,imx-elcdif` has replaced ``fsl,imx6sx-lcdif`` * :dtcompatible:`nxp,imx-gpr` has replaced ``nxp,imx-pinmux`` * :dtcompatible:`nordic,nrf-wdt` has replaced ``nordic,nrf-watchdog`` * :dtcompatible:`bosch,m_can-base` has replaced ``bosch,m-can-base`` * :dtcompatible:`nxp,imx-usdhc` has replaced ``nxp,imx-sdhc`` * Bindings with ``resets`` (and optionally ``reset-names``) properties were added to support the :ref:`reset_api` API. See the list of new bindings below for some examples. * The ``zephyr,memory-region-mpu`` property can be set to generate MPU regions from devicetree nodes. See commit `b91d21d32c <path_to_url`_ * The generic :zephyr_file:`dts/bindings/can/can-controller.yaml` include file used for defining CAN controller bindings no longer contains a ``bus: yaml`` statement. This was unused in upstream Zephyr; out of tree bindings relying on this will need updates. * Bindings for ADC controller nodes can now use a child binding to specify the initial configuration of individual channels in devicetree. See pull request `43030 <path_to_url`_ for details. * New bindings for the following compatible properties were added: * :dtcompatible:`arduino-nano-header-r3` * :dtcompatible:`arm,cortex-r52` * :dtcompatible:`atmel,sam-rstc` * :dtcompatible:`can-transceiver-gpio` (see also :ref:`devicetree-can-api`) * :dtcompatible:`gd,gd32-spi` * :dtcompatible:`hynitron,cst816s` * :dtcompatible:`intel,cavs-gpdma` * :dtcompatible:`intel,cavs-hda-host-in` and :dtcompatible:`intel,cavs-hda-host-out` * :dtcompatible:`intel,cavs-hda-link-in` and :dtcompatible:`intel,cavs-hda-link-out` * :dtcompatible:`intel,ssp-dai` * :dtcompatible:`intel,ssp-sspbase` * :dtcompatible:`invensense,icm42670` * :dtcompatible:`ite,enhance-i2c` * :dtcompatible:`ite,it8xxx2-vcmp` * :dtcompatible:`ite,it8xxx2-wuc` and :dtcompatible:`ite,it8xxx2-wuc-map` * :dtcompatible:`ite,peci-it8xxx2` * :dtcompatible:`maxim,max31875` * :dtcompatible:`microchip,cap1203` * :dtcompatible:`microchip,mcp4728` * :dtcompatible:`microchip,mpfs-qspi` * :dtcompatible:`microchip,xec-bbram` * :dtcompatible:`motorola,mc146818` * :dtcompatible:`nordic,nrf-acl` * :dtcompatible:`nordic,nrf-bprot` * :dtcompatible:`nordic,nrf-ccm` * :dtcompatible:`nordic,nrf-comp` * :dtcompatible:`nordic,nrf-ctrlapperi` * :dtcompatible:`nordic,nrf-dcnf` * :dtcompatible:`nordic,nrf-gpio-forwarder` * :dtcompatible:`nordic,nrf-lpcomp` * :dtcompatible:`nordic,nrf-mpu` * :dtcompatible:`nordic,nrf-mutex` * :dtcompatible:`nordic,nrf-mwu` * :dtcompatible:`nordic,nrf-nfct` * :dtcompatible:`nordic,nrf-oscillators` * :dtcompatible:`nordic,nrf-ppi` * :dtcompatible:`nordic,nrf-reset` * :dtcompatible:`nordic,nrf-swi` * :dtcompatible:`nordic,nrf-usbreg` * :dtcompatible:`nuvoton,adc-cmp` * :dtcompatible:`nxp,imx-mipi-dsi` * :dtcompatible:`nxp,imx-qtmr` * :dtcompatible:`nxp,imx-tmr` * :dtcompatible:`raspberrypi,pico-reset` * :dtcompatible:`raspberrypi,pico-usbd` * :dtcompatible:`raydium,rm68200` * :dtcompatible:`riscv,sifive-e31`, :dtcompatible:`riscv,sifive-e51`, and :dtcompatible:`riscv,sifive-s7` CPU bindings * :dtcompatible:`seeed,grove-lcd-rgb` * :dtcompatible:`st,lsm6dso32` * :dtcompatible:`st,stm32-clock-mux` * :dtcompatible:`st,stm32-fmc-nor-psram` * :dtcompatible:`st,stm32-lse-clock` * :dtcompatible:`st,stm32-ltdc` * :dtcompatible:`st,stm32-ospi` and :dtcompatible:`st,stm32-ospi-nor` * :dtcompatible:`st,stm32h7-fmc` * TI ADS ADCs: :dtcompatible:`ti,ads1013`, :dtcompatible:`ti,ads1015`, :dtcompatible:`ti,ads1113`, :dtcompatible:`ti,ads1114`, :dtcompatible:`ti,ads1115`, :dtcompatible:`ti,ads1014` * :dtcompatible:`ti,tlc5971` * :dtcompatible:`xlnx,fpga` * :dtcompatible:`xlnx,ps-gpio` and :dtcompatible:`xlnx,ps-gpio-bank` * :dtcompatible:`zephyr,bt-hci-entropy` * :dtcompatible:`zephyr,ipc-icmsg` * :dtcompatible:`zephyr,memory-region` * :dtcompatible:`zephyr,sdhc-spi-slot` * Bindings for the following compatible properties were removed: * ``bosch,m-can`` * ``nxp,imx-usdhc`` * ``shared-multi-heap`` * ``snps,creg-gpio-mux-hsdk`` * ``snps,designware-pwm`` * ``zephyr,mmc-spi-slot`` * Numerous other additional properties were added to bindings throughout the tree. Libraries / Subsystems ********************** * C Library * Minimal libc * Added ``[U]INT_{FAST,LEAST}N_{MIN,MAX}`` minimum and maximum value macros in ``stdint.h``. * Added ``PRIx{FAST,LEAST}N`` and ``PRIxMAX`` format specifier macros in ``inttypes.h``. * Fixed ``gmtime()`` access fault when userspace is enabled and ``gmtime()`` is called from a user mode thread. This function can be safely called from both kernel and user mode threads. * Newlib * Fixed access fault when calling the newlib math functions from a user mode thread. All ``libm.a`` globals are now placed into the ``z_libc_partition`` when userspace is enabled. * C++ Subsystem * Renamed all C++ source and header files to use the ``cpp`` and ``hpp`` extensions, respectively. All Zephyr upstream C++ source and header files are now required to use these extensions. * Management * MCUMGR has been migrated from using TinyCBOR, for CBOR encoding, to zcbor. * MCUMGR :kconfig:option:`CONFIG_FS_MGMT_UL_CHUNK_SIZE` and :kconfig:option:`CONFIG_IMG_MGMT_UL_CHUNK_SIZE` have been deprecated as, with the introduction of zcbor, it is no longer needed to use an intermediate buffer to copy data out of CBOR encoded buffer. The file/image chunk size is now limited by :kconfig:option:`CONFIG_MCUMGR_BUF_SIZE` minus all the other command required variables. * Added support for MCUMGR Parameters command, which can be used to obtain MCUMGR parameters; :kconfig:option:`CONFIG_OS_MGMT_MCUMGR_PARAMS` enables the command. * Added mcumgr fs handler for getting file status which returns file size; controlled with :kconfig:option:`CONFIG_FS_MGMT_FILE_STATUS` * Added mcumgr fs handler for getting file hash/checksum, with support for IEEE CRC32 and SHA256, the following Kconfig options have been added to control the addition: * :kconfig:option:`CONFIG_FS_MGMT_CHECKSUM_HASH` to enable the command; * :kconfig:option:`CONFIG_FS_MGMT_CHECKSUM_HASH_CHUNK_SIZE` that sets size of buffer (stack memory) used for calculation: * :kconfig:option:`CONFIG_FS_MGMT_CHECKSUM_IEEE_CRC32` enables support for IEEE CRC32. * :kconfig:option:`CONFIG_FS_MGMT_HASH_SHA256` enables SHA256 hash support. * When hash/checksum query to mcumgr does not specify a type, then the order of preference (most priority) is CRC32 followed by SHA256. * Added mcumgr os hook to allow an application to accept or decline a reset request; :kconfig:option:`CONFIG_OS_MGMT_RESET_HOOK` enables the callback. * Added mcumgr fs hook to allow an application to accept or decline a file read/write request; :kconfig:option:`CONFIG_FS_MGMT_FILE_ACCESS_HOOK` enables the feature which then needs to be registered by the application. * Added supplied image header to mcumgr img upload callback parameter list which allows the application to inspect it to determine if it should be allowed or declined. * Made the ``img_mgmt_vercmp()`` function public to allow application- level comparison of image versions. * mcumgr will now only return ``MGMT_ERR_ENOMEM`` when it fails to allocate a memory buffer for request processing, when previously it would wrongly report this error when the SMP response failed to fit into a buffer; now when encoding of response fails ``MGMT_ERR_EMSGSIZE`` will be reported. This addresses issue :github:`44535`. * Added :kconfig:option:`CONFIG_IMG_MGMT_USE_HEAP_FOR_FLASH_IMG_CONTEXT` that allows user to select whether the heap will be used for flash image context, when heap pool is configured. Previously usage of heap has been implicit, with no control from a developer, causing issues reported by :github:`44214`. The default, implicit, behaviour has not been kept and the above Kconfig option needs to be selected to keep previous behaviour. * SD Subsystem * Added the SD subsystem, which is used by the :ref:`disk access api <disk_access_api>` to interact with connected SD cards. This subsystem uses the :ref:`SDHC api <sdhc_api>` to interact with the SD host controller the SD device is connected to. * Power management * Added :kconfig:option:`CONFIG_PM_DEVICE_POWER_DOMAIN_DYNAMIC`. This option enables support for dynamically bind devices to a Power Domain. The memory required to dynamically bind devices is pre-allocated at build time and is based on the number of devices set in :kconfig:option:`CONFIG_PM_DEVICE_POWER_DOMAIN_DYNAMIC_NUM`. The API introduced to use this feature are: * :c:func:`pm_device_power_domain_add()` * :c:func:`pm_device_power_domain_remove()` * The default policy was renamed from ``PM_POLICY_RESIDENCY`` to ``PM_POLICY_DEFAULT``, and ``PM_POLICY_APP`` was renamed to ``PM_POLICY_CUSTOM``. * The following functions were renamed: * :c:func:`pm_power_state_next_get()` is now :c:func:`pm_state_next_get()` * :c:func:`pm_power_state_force()` is now :c:func:`pm_state_force()` * Removed the deprecated function :c:func:`pm_device_state_set()`. * The state constraint APIs were moved (and renamed) to the policy API and accounts substates. * :c:func:`pm_constraint_get()` is now :c:func:`pm_policy_state_lock_is_active()` * :c:func:`pm_constraint_set()` is now :c:func:`pm_policy_state_lock_get()` * :c:func:`pm_constraint_release()` is now :c:func:`pm_policy_state_lock_put()` * Added a new API to set maximum latency requirements. The ``DEFAULT`` policy will account for latency when computing the next state. * :c:func:`pm_policy_latency_request_add()` * :c:func:`pm_policy_latency_request_update()` * :c:func:`pm_policy_latency_request_remove()` * The API to set a device initial state was changed to be usable independently of :kconfig:option:`CONFIG_PM_DEVICE_RUNTIME`. * :c:func:`pm_device_runtime_init_suspended()` is now :c:func:`pm_device_init_suspended()` * :c:func:`pm_device_runtime_init_off()` is now :c:func:`pm_device_init_off()` * IPC * static_vrings: Fixed work queue (WQ) initialization * static_vrings: Introduced atomic helpers when accessing atomic_t variables * static_vrings: Moved to one WQ per instance * static_vrings: Added "zephyr,priority" property in the DT to set the WQ priority of the instance * static_vrings: Added configuration parameter to initialize shared memory to zero * Extended API with NOCOPY functions * static_vrings: Added support for NOCOPY operations * Introduced inter core messaging backend (icmsg) that relies on simple inter core messaging buffer * Logging * Added UART frontend which supports binary dictionary logging. * Added support for MIPI SyS-T catalog messages. * Added cAVS HDA backend. * Shell * Added API for creating subcommands from multiple files using memory section approach: * :c:macro:`SHELL_SUBCMD_SET_CREATE` for creating a subcommand set. * :c:macro:`SHELL_SUBCMD_COND_ADD` and :c:macro:`SHELL_SUBCMD_ADD` for adding subcommands to the set.

```restructuredtext :orphan: .. _zephyr_2.3: Zephyr 2.3.0 ############ We are pleased to announce the release of Zephyr RTOS version 2.3.0. Major enhancements with this release include: * A new Zephyr CMake package has been introduced, reducing the need for environment variables * A new Devicetree API, based on hierarchical macros, has been introduced. This new API allows the C code to access virtually all nodes and properties in a clean, organized fashion * The kernel timeout API has been overhauled to be flexible and configurable, with future support for features like 64-bit and absolute timeouts in mind * A new k_heap/sys_heap heap allocator has been introduced, with much better performance than the existing k_mem_pool/sys_mem_pool * Zephyr now integrates with the TF-M (Trusted Firmware M) PSA-compliant framework * The Bluetooth Low Energy Host now supports LE Advertising Extensions * The CMSIS-DSP library is now included and integrated The following sections provide detailed lists of changes by component. Security Vulnerability Related ****************************** The following CVEs are addressed by this release: * CVE-2020-10022: UpdateHub Module Copies a Variable-Sized Hash String into a fixed-size array. * CVE-2020-10059: UpdateHub Module Explicitly Disables TLS Verification * CVE-2020-10061: Improper handling of the full-buffer case in the Zephyr Bluetooth implementation can result in memory corruption. * CVE-2020-10062: Packet length decoding error in MQTT * CVE-2020-10063: Remote Denial of Service in CoAP Option Parsing Due To Integer Overflow * CVE-2020-10068: In the Zephyr project Bluetooth subsystem, certain duplicate and back-to-back packets can cause incorrect behavior, resulting in a denial of service. * CVE-2020-10069: An unchecked parameter in bluetooth data can result in an assertion failure, or division by zero, resulting in a denial of service attack. * CVE-2020-10070: MQTT buffer overflow on receive buffer * CVE-2020-10071: Insufficient publish message length validation in MQTT More detailed information can be found in: path_to_url Known issues ************ You can check all currently known issues by listing them using the GitHub interface and listing all issues with the `bug label <path_to_url`_. A single high-priority bug is currently open: * :github:`23364` - Bluetooth: bt_recv deadlock on supervision timeout with pending GATT Write Commands API Changes *********** * HWINFO * The identifier data structure for hwinfo drivers is clarified. Drivers are responsible for ensuring that the identifier data structure is a sequence of bytes. The returned ID value is not supposed to be interpreted based on vendor-specific assumptions of byte order and should express the identifier as a raw byte sequence. The changes have an impact on users that use the hwinfo API to identify their devices. The sam0 driver byte swaps each 32 bit word of the 128 bit identifier to big endian. The nordic driver byte swaps the entire 64 bit word to big endian. * I2C * Added a new API for recovering an I2C bus from situations where the I2C master and one or more I2C slaves are out of synchronization (e.g. if the I2C master was reset in the middle of an I2C transaction or if a noise pulse was induced on the SCL line). Deprecated in this release ========================== * Kernel * k_uptime_delta_32(), use k_uptime_delta() * Timeout values * All timeout values are now encapsulated k_timeout_t opaque structure when passing them to the kernel. If you want to revert to the previous s32_t type for the timeout parameter, please enable CONFIG_LEGACY_TIMEOUT_API * Bluetooth * BT_LE_SCAN_FILTER_DUPLICATE, use BT_LE_SCAN_OPT_FILTER_DUPLICATE instead * BT_LE_SCAN_FILTER_WHITELIST, use BT_LE_SCAN_OPT_FILTER_WHITELIST instead * bt_le_scan_param::filter_dup, use bt_le_scan_param::options instead * bt_conn_create_le(), use bt_conn_le_create() instead * bt_conn_create_auto_le(), use bt_conn_le_create_auto() instead * bt_conn_create_slave_le(), use bt_le_adv_start() instead with bt_le_adv_param::peer set to the remote peers address. * BT_LE_ADV_* macros, use BT_GAP_ADV_* enums instead * Boards * nrf51_pca10028 has been renamed to nrf51dk_nrf51422 * nrf51_pca10031 has been renamed to nrf51dongle_nrf51422 * nrf52810_pca10040 has been renamed to nrf52dk_nrf52810 * nrf52_pca10040 has been renamed to nrf52dk_nrf52832 * nrf52833_pca10100 has been renamed to nrf52833dk_nrf52833 * nrf52811_pca10056 has been renamed to nrf52840dk_nrf52811 * nrf52840_pca10056 has been renamed to nrf52840dk_nrf52840 * nrf52840_pca10059 has been renamed to nrf52840dongle_nrf52840 * nrf9160_pca10090 has been renamed to nrf9160dk_nrf9160 * nrf52840_pca10090 has been renamed to nrf9160dk_nrf52840 * nrf52_pca20020 has been renamed to thingy52_nrf52832 * nrf5340_dk_nrf5340 has been renamed to nrf5340pdk_nrf5340 * efr32_slwstk6061a has been renamed to efr32_radio_brd4250b * Devicetree * The C macros generated from the devicetree in previous releases are now deprecated in favor of a new ``<devicetree.h>`` API. * See :ref:`dt-from-c` for a high-level guide to the new API, and :ref:`devicetree_api` for an API reference. * Use of the legacy macros now requires explicitly enabling ``CONFIG_LEGACY_DEVICETREE_MACROS``. See `the Zephyr v2.3 legacy devicetree macro page`_ for more information, including a link to a migration guide to the new API. .. _the Zephyr v2.3 legacy devicetree macro page: path_to_url#dt-legacy-macros * Other * ``MACRO_MAP`` has been deprecated. Use ``FOR_EACH`` instead. * ``BUILD_ASSERT_MSG`` has been deprecated. Use ``BUILD_ASSERT`` instead. Removed APIs in this release ============================ * The ``INLINE`` macro in ``util.h`` has been removed. * ``STACK_ANALYZE``, ``stack_analyze`` and ``stack_unused_space_get`` have been removed. Stable API changes in this release ================================== * Bluetooth Mesh * The net_idx parameter has been removed from the Health Client model APIs since it can be derived (by the stack) from the app_idx parameter * Networking * The NET_DEVICE_INIT(), NET_DEVICE_INIT_INSTANCE(), NET_DEVICE_OFFLOAD_INIT() and ETH_NET_DEVICE_INIT() macros changed and take a device power management function pointer parameter. If networking PM is not implemented for the specific network device, the device_pm_control_nop value can be used. * Video * The video_dequeue() API call now takes a k_timeout_t for the timeout parameter. This reverts to s32_t if CONFIG_LEGACY_TIMEOUT_API is enabled. * Floating Point Services * FLOAT and FP_SHARING Kconfig options have been renamed to FPU and FPU_SHARING, respectively. Kernel ****** * A new general purpose memory allocator, sys_heap/k_heap, has been added to Zephyr with more conventional API/behavior, better space efficiency and higher performance than the pre-existing mem_pool. The older mem_pool APIs are, by default, wrappers around this new heap backend and will be deprecated in an upcoming release. The original implementation remains available for this release via disabling CONFIG_MEM_POOL_HEAP_BACKEND. * The timeout arguments to all kernel calls are now a "k_timeout_t" type instead of a 32 bit millisecond count. These can be initialized in arbitrary time units (ns/us/ms, ticks), be interpreted relative to either current time or system start, and be expressed in 64 bit quantities. This involves a minor change to the API, so the original API is still available in a completely source-compatible way via CONFIG_LEGACY_TIMEOUT_API. * Simplified dummy thread implementation and properly name idle threads * Centralized new thread priority check * Refactored device structures and introduced struct init_entry which is a generic init end-point. SYS_INIT() generates only a struct init_entry via calling INIT_ENTRY_DEFINE(). Also removed struct deviceconfig leaving struct device to own everything now.

Build and Infrastructure ************************ * Zephyr CMake package * The Zephyr main repository now includes a Zephyr CMake package. This allows for registering Zephyr in the CMake user package registry and allows for easier integration into Zephyr applications, by using the CMake function, ``find_package(Zephyr ...)``. Registering the Zephyr CMake package in the CMake user package registry removes the need for setting of ``ZEPHYR_BASE``, sourcing ``zephyr-env.sh``, or running ``zephyr-env.cmd``. * A new ``west`` extension command, ``west zephyr-export`` is introduced for easy registration of Zephyr CMake package in the CMake user package registry. * Zephyr Build Configuration CMake package hook. Zephyr offers the possibility of configuring the Zephyr build system through a Zephyr Build Configuration package. A single Zephyr workspace ``ZephyrBuildConfig.cmake`` will be loaded if present in the Zephyr workspace. This allows users to configure the Zephyr build system on a per workspace setup, as an alternative to using a ``.zephyrrc`` system wide file. * Devicetree * A new :ref:`devicetree_api` was added. This API is not generated, but is still included via ``<devicetree.h>``. See `the Zephyr v2.3 legacy devicetree macro page`_ for more information, including a link to a migration guide to the new API. The :ref:`dt-howtos` page has been extended for the new API, and a new :ref:`dt-from-c` API usage guide was also added. Libraries / Subsystems ********************** * Disk * Add stm32 sdmmc disk access driver, supports stm32f7 and stm32l4 * Random * Removed the ``rand32_timestamp`` driver. * POSIX subsystem: * socketpair() function implemented. * eventfd() function (Linux-like extension) implemented. * Power management: * Add system and device power management support on TI CC13x2/CC26x2. HALs **** * HALs are now moved out of the main tree as external modules and reside in their own standalone repositories. Documentation ************* * New API overview page added. * Reference pages have been cleaned up and organized. * The Devicetree documentation has been expanded significally. * The project roles have been overhauled in the Contribution Guidelines pages. * The documentation on driver-specific APIs has been simplified. * Documentation for new APIs, boards and samples. Tests and Samples ***************** * Added samples for USB Audio Class. * Added sample for using POSIX read()/write() with network sockets.

This adds support for IPv4 link-local addresses (169.254..) * Add TLS and DTLS support to BSD socket API. They are configured via setsockopt() API. * Add support for IEEE 802.1AS-2011 generalized Precision Time Protocol (gPTP) for ethernet networks. A sample application is created to show how to interact with gPTP code. * Add support for PTP clock driver. This driver will be used by gPTP supported ethernet drivers. * Add Link Layer Discovery Protocol (LLDP) TX support. * Add support for managing Qav credit-based shaper algorithm. * Add generic TX timestamping support. * Add carrier detection support to ethernet L2 driver. * Add support for having vendor specific ethernet statistics. * Add getter support to ethernet management interface. * Add promiscuous mode support to network interface. A sample application is created that shows how to use the user API for getting all network packets. The native_posix ethernet driver supports promiscuous mode at this point. * Add support for Link Layer Multicast Name Resolution (LLMNR). LLMNR is used in Microsoft Windows networks for local name resolution. * Add API to net_pkt to prefill a network packet to a pre-defined value. * Add IEEE 802.1Qav support to Atmel GMAC ethernet driver. * Add hardware TX timestamping support to Atmel GMAC ethernet driver. * Add multiple hardware queue support to Atmel GMAC ethernet driver. * Add gPTP support to Atmel GMAC ethernet driver. * Add support for TI SimpleLink WiFI offload driver. * Add support for randomized but stable MAC address in NXP MCUX ethernet driver. * Add extra prints to net-shell for ethernet based network interfaces.

```restructuredtext :orphan: .. _zephyr_3.0: Zephyr 3.0.0 ############ We are pleased to announce the release of Zephyr RTOS version 3.0.0. The following sections provide detailed lists of changes by component. Security Vulnerability Related ****************************** The following CVEs are addressed by this release: More detailed information can be found in: path_to_url * CVE-2021-3835: `Zephyr project bug tracker GHSA-fm6v-8625-99jf <path_to_url`_ * CVE-2021-3861: `Zephyr project bug tracker GHSA-hvfp-w4h8-gxvj <path_to_url`_ * CVE-2021-3966: `Zephyr project bug tracker GHSA-hfxq-3w6x-fv2m <path_to_url`_ Known issues ********** You can check all currently known issues by listing them using the GitHub interface and listing all issues with the `bug label <path_to_url`_. API Changes ********* Changes in this release ======================= * Following functions in UART Asynchronous API are using microseconds to represent timeout instead of milliseconds: * :c:func:`uart_tx` * :c:func:`uart_rx_enable` * Replaced custom LwM2M :c:struct:`float32_value` type with a native double type. * Added function for getting status of USB device remote wakeup feature. * Added ``ranges`` and ``dma-ranges`` as invalid property to be used with DT_PROP_LEN() along ``reg`` and ``interrupts``. * The existing :c:func:`crc16` and :c:func:`crc16_ansi` functions have been modified. The former has a new signature. The latter now properly calculates the CRC-16-ANSI checksum. A new function, :c:func:`crc16_reflect`, has been introduced to calculated reflected CRCs. * GATT callbacks ``bt_gatt_..._func_t`` would previously be called with argument ``conn = NULL`` in the event of a disconnect. This was not documented as part of the API. This behavior is changed so the ``conn`` argument is provided as normal when a disconnect occurs. Removed APIs in this release ============================ * The following Kconfig options related to radio front-end modules (FEMs) were removed: * ``CONFIG_BT_CTLR_GPIO_PA`` * ``CONFIG_BT_CTLR_GPIO_PA_PIN`` * ``CONFIG_BT_CTLR_GPIO_PA_POL_INV`` * ``CONFIG_BT_CTLR_GPIO_PA_OFFSET`` * ``CONFIG_BT_CTLR_GPIO_LNA`` * ``CONFIG_BT_CTLR_GPIO_LNA_PIN`` * ``CONFIG_BT_CTLR_GPIO_LNA_POL_INV`` * ``CONFIG_BT_CTLR_GPIO_LNA_OFFSET`` * ``CONFIG_BT_CTLR_FEM_NRF21540`` * ``CONFIG_BT_CTLR_GPIO_PDN_PIN`` * ``CONFIG_BT_CTLR_GPIO_PDN_POL_INV`` * ``CONFIG_BT_CTLR_GPIO_CSN_PIN`` * ``CONFIG_BT_CTLR_GPIO_CSN_POL_INV`` * ``CONFIG_BT_CTLR_GPIO_PDN_CSN_OFFSET`` This FEM configuration is hardware description, and was therefore moved to :ref:`devicetree <dt-guide>`. See the :dtcompatible:`nordic,nrf-radio` devicetree binding's ``fem`` property for information on what to do instead on the Nordic open source controller. * Removed Kconfig option ``CONFIG_USB_UART_CONSOLE``. Option ``CONFIG_USB_UART_CONSOLE`` was only relevant for console driver when CDC ACM UART is used as backend. Since the behavior of the CDC ACM UART is changed so that it more closely mimics the real UART controller, option is no longer necessary. * Removed Kconfig option ``CONFIG_OPENOCD_SUPPORT`` in favor of ``CONFIG_DEBUG_THREAD_INFO``. * Removed ``flash_write_protection_set()`` along with the flash write protection implementation handler. * Removed ``CAN_BUS_UNKNOWN`` and changed the signature of :c:func:`can_get_state` to return an error code instead. * Removed ``DT_CHOSEN_ZEPHYR_CANBUS_LABEL`` in favor of utilizing :c:macro:`DEVICE_DT_GET`. * Removed ``CONFIG_LOG_MINIMAL``. Use ``CONFIG_LOG_MODE_MINIMAL`` instead. * STM32 clock_control driver configuration was moved from Kconfig to :ref:`devicetree <dt-guide>`. See the :dtcompatible:`st,stm32-rcc` devicetree binding for more information. As a consequence, following Kconfig symbols were removed: * ``CONFIG_CLOCK_STM32_SYSCLK_SRC_HSE`` * ``CONFIG_CLOCK_STM32_SYSCLK_SRC_HSI`` * ``CONFIG_CLOCK_STM32_SYSCLK_SRC_MSI`` * ``CONFIG_CLOCK_STM32_SYSCLK_SRC_PLL`` * ``CONFIG_CLOCK_STM32_SYSCLK_SRC_CSI`` * ``CONFIG_CLOCK_STM32_HSE_BYPASS`` * ``CONFIG_CLOCK_STM32_MSI_RANGE`` * ``CONFIG_CLOCK_STM32_PLL_SRC_MSI`` * ``CONFIG_CLOCK_STM32_PLL_SRC_HSI`` * ``CONFIG_CLOCK_STM32_PLL_SRC_HSE`` * ``CONFIG_CLOCK_STM32_PLL_SRC_PLL2`` * ``CONFIG_CLOCK_STM32_PLL_SRC_CSI`` * ``CONFIG_CLOCK_STM32_AHB_PRESCALER`` * ``CONFIG_CLOCK_STM32_APB1_PRESCALER`` * ``CONFIG_CLOCK_STM32_APB2_PRESCALER`` * ``CONFIG_CLOCK_STM32_CPU1_PRESCALER`` * ``CONFIG_CLOCK_STM32_CPU2_PRESCALER`` * ``CONFIG_CLOCK_STM32_AHB3_PRESCALER`` * ``CONFIG_CLOCK_STM32_AHB4_PRESCALER`` * ``CONFIG_CLOCK_STM32_PLL_PREDIV`` * ``CONFIG_CLOCK_STM32_PLL_PREDIV1`` * ``CONFIG_CLOCK_STM32_PLL_MULTIPLIER`` * ``CONFIG_CLOCK_STM32_PLL_XTPRE`` * ``CONFIG_CLOCK_STM32_PLL_M_DIVISOR`` * ``CONFIG_CLOCK_STM32_PLL_N_MULTIPLIER`` * ``CONFIG_CLOCK_STM32_PLL_P_DIVISOR`` * ``CONFIG_CLOCK_STM32_PLL_Q_DIVISOR`` * ``CONFIG_CLOCK_STM32_PLL_R_DIVISOR`` * ``CONFIG_CLOCK_STM32_LSE`` * ``CONFIG_CLOCK_STM32_HSI_DIVISOR`` * ``CONFIG_CLOCK_STM32_D1CPRE`` * ``CONFIG_CLOCK_STM32_HPRE`` * ``CONFIG_CLOCK_STM32_D2PPRE1`` * ``CONFIG_CLOCK_STM32_D2PPRE2`` * ``CONFIG_CLOCK_STM32_D1PPRE`` * ``CONFIG_CLOCK_STM32_D3PPRE`` * ``CONFIG_CLOCK_STM32_PLL3_ENABLE`` * ``CONFIG_CLOCK_STM32_PLL3_M_DIVISOR`` * ``CONFIG_CLOCK_STM32_PLL3_N_MULTIPLIER`` * ``CONFIG_CLOCK_STM32_PLL3_P_ENABLE`` * ``CONFIG_CLOCK_STM32_PLL3_P_DIVISOR`` * ``CONFIG_CLOCK_STM32_PLL3_Q_ENABLE`` * ``CONFIG_CLOCK_STM32_PLL3_Q_DIVISOR`` * ``CONFIG_CLOCK_STM32_PLL3_R_ENABLE`` * ``CONFIG_CLOCK_STM32_PLL3_R_DIVISOR`` * ``CONFIG_CLOCK_STM32_PLL_DIVISOR`` * ``CONFIG_CLOCK_STM32_MSI_PLL_MODE`` Deprecated in this release ========================== * Removed ``<power/reboot.h>`` and ``<power/power.h>`` deprecated headers. ``<sys/reboot.h>`` and ``<pm/pm.h>`` should be used instead. * :c:macro:`USBD_CFG_DATA_DEFINE` is deprecated in favor of utilizing :c:macro:`USBD_DEFINE_CFG_DATA` * :c:macro:`SYS_DEVICE_DEFINE` is deprecated in favor of utilizing :c:macro:`SYS_INIT`. * :c:func:`device_usable_check` is deprecated in favor of utilizing :c:func:`device_is_ready`. * Custom CAN return codes (:c:macro:`CAN_TX_OK`, :c:macro:`CAN_TX_ERR`, :c:macro:`CAN_TX_ARB_LOST`, :c:macro:`CAN_TX_BUS_OFF`, :c:macro:`CAN_TX_UNKNOWN`, :c:macro:`CAN_TX_EINVAL`, :c:macro:`CAN_NO_FREE_FILTER`, and :c:macro:`CAN_TIMEOUT`) are deprecated in favor of utilizing standard errno error codes. * :c:func:`can_configure` is deprecated in favor of utilizing :c:func:`can_set_bitrate` and :c:func:`can_set_mode`. * :c:func:`can_attach_workq` is deprecated in favor of utilizing :c:func:`can_add_rx_filter_msgq` and :c:func:`k_work_poll_submit`. * :c:func:`can_attach_isr` is deprecated and replaced by :c:func:`can_add_rx_filter`. * :c:macro:`CAN_DEFINE_MSGQ` is deprecated and replaced by :c:macro:`CAN_MSGQ_DEFINE`. * :c:func:`can_attach_msgq` is deprecated and replaced by :c:func:`can_add_rx_filter_msgq`. * :c:func:`can_detach` is deprecated and replaced by :c:func:`can_remove_rx_filter`. * :c:func:`can_register_state_change_isr` is deprecated and replaced by :c:func:`can_set_state_change_callback`. * :c:func:`can_write` is deprecated in favor of utilizing :c:func:`can_send`.

been moved to implementations of the flash_write() and the flash_erase() calls. The driver was keeping the write protection API which was designed to be removed since 2.6 release. * GPIO * Added driver for GigaDevice GD32 SoCs * I2C * Added driver for GigaDevice GD32 SoCs * Added stats functionality to all drivers * Added I2C driver for Renesas R-Car platform * Added support for TCA9548A I2C switch * I2S * mimxrt10xx: Added support for I2S * mimxrt11xx: Added support for I2S * Interrupt Controller * Added ECLIC driver for GigaDevice RISC-V GD32 SoCs * Added EXTI driver for GigaDevice GD32 SoCs * MBOX * Added MBOX NRFX IPC driver * MEMC * Added support for stm32f7 series * Pin control * Introduced a new state-based pin control (``pinctrl``) API inspired by the Linux design principles. The ``pinctrl`` API will replace the existing pinmux API, so all platforms using pinmux are encouraged to migrate. A detailed guide with design principles and implementation guidelines can be found in :ref:`pinctrl-guide`. * Platforms already supporting the ``pinctrl`` API: * GigaDevice GD32 * Nordic (preliminary support) * Renesas R-Car * STM32 * PWM * stm32: DT bindings: `st,prescaler` property was moved from pwm to parent timer node. * stm32: Implemented PWM capture API * Added driver for GigaDevice GD32 SoCs.

Polling and interrupt driven modes are supported. * SPI * stm32: Implemented Frame format option (TI vs Motorola). * mimxrt11xx: Added support for Flexspi * Timer * stm32 lptim: Added support for stm32h7 * USB * Added support for stm32u5 series (OTG full speed) * Watchdog * Added support for stm32u5 series (Independent and Window) * mimxrt1170: Added support for watchdog on CM7 Networking ********** * CoAP: * Refactored ``coap_client``/``coap_server`` samples to make better use of observe APIs. * Added PATCH, iPATCH and FETCH methods. * A few fixes for the block transfer handling. * DNS: * Make mdns and llmnr responders join their multicast groups. * Added support for mdns/dns_sd service type enumeration. * ICMPv6: * Added support for Route Information option processing. * IPv4: * Add IPv4 support to multicast monitor. * LwM2M: * Added a parameter to forcefully close the LwM2M session to :c:func:`lwm2m_rd_client_stop` function. * Replaced custom ``float32_value_t`` type with double. * Added :kconfig:option:`LWM2M_FIRMWARE_PORT_NONSECURE`/ :kconfig:option:`LWM2M_FIRMWARE_PORT_SECURE` options, which allow to specify a custom port or firmware update. * Added :c:func:`lwm2m_update_device_service_period` API function. * Added observe callback for observe and notification events. * Added support for multiple LwM2M Firmware Update object instances. * Improved error handling in LwM2M content writers. * Added unit tests for LwM2M content writers. * Implemented LwM2M Security, Server, Connection Monitor objects in version 1.1. * Multiple minor bugfixes in the LwM2M stack. * Added support for the following objects: * LWM2M Software Management (ID 9) * LwM2M Gateway (ID 25) * IPSO Current (ID 3317) * uCIFI Battery (ID 3411) * IPSO Filling level (ID 3435) * Misc: * gptp: clock sync ratio as double, not float * Added support for route lifetime and preference. * Refactored various packed structures across the networking stack, to avoid unaliged access warnings from gcc. * Added automatic loopback addresses registration to loopback interface. * Fixed source address selection for ARP. * Allow to implement a custom IEEE802154 L2 on top of existing drivers. * Introduced a network packet filtering framework. * MQTT: * Fixed incomplete :c:func:`zsock_sendmsg` writes handling. * Fixed :c:func:`zsock_setsockopt` error handling in SOCKS5 transport. * OpenThread: * Updated OpenThread revision up to commit ``ce77ab3c1d7ad91b284615112ae38c08527bf73e``. * Fixed an overflow bug in the alarm implementation for Zephyr. * Added crypto backend based on PSA API. * Allow to store OpenThread settings in RAM. * Socket: * Fixed :c:func:`zsock_sendmsg` when payload size exceeded network MTU. * Added socket processing priority. * Fixed possible crash in :c:func:`zsock_getaddrinfo` when DNS callback is delayed. * Telnet: * Fixed handling of multiple commands in a single packet. * Enabled command handling by default. * TCP: * Added support for sending our MSS to peer. * Fixed packet sending to local addresses. * Fixed possible deadlock between TCP and socket layer, when connection close is initiated from both sides. * Multiple other minor bugfixes and improvements in the TCP implementation. * TLS: * Added support for ``TLS_CERT_NOCOPY`` socket option, which allows to optimise mbed TLS heap usage. * Fixed ``POLLHUP`` detection when underlying TCP connection is closed. * Fixed mbedtls session reset on handshake errors. USB * Build and Infrastructure ********************** * Build system * New CMake extension functions: * ``dt_alias()`` * ``target_sources_if_dt_node()`` * The following CMake extension functions now handle devicetree aliases: * ``dt_node_exists()`` * ``dt_node_has_status()`` * ``dt_prop()`` * ``dt_num_regs()`` * ``dt_reg_addr()`` * ``dt_reg_size()`` * Devicetree * Support for the devicetree compatible ``ti,ina23x`` has been removed. Instead, use :dtcompatible:`ti,ina230` or :dtcompatible:`ti,ina237`. * West (extensions) * Added support for gd32isp runner Libraries / Subsystems ********************** * Management * Fixed the mcumgr SMP protocol over serial not adding the length of the CRC16 to packet length. * Kconfig option OS_MGMT_TASKSTAT is now disabled by default. * Power management * Power management resources are now manually allocated by devices using :c:macro:`PM_DEVICE_DEFINE`, :c:macro:`PM_DEVICE_DT_DEFINE` or :c:macro:`PM_DEVICE_DT_INST_DEFINE`. Device instantiation macros take now a reference to the allocated resources. The reference can be obtained using :c:macro:`PM_DEVICE_GET`, :c:macro:`PM_DEVICE_DT_GET` or :c:macro:`PM_DEVICE_DT_INST_GET`. Thanks to this change, devices not implementing support for device power management will not use unnecessary memory. * Device runtime power management API error handling has been simplified. * :c:func:`pm_device_runtime_enable` suspends the target device if not already suspended. This change makes sure device state is always kept in a consistent state. * Improved PM states Devicetree macros naming * Added a new API call :c:func:`pm_state_cpu_get_all` to obtain information about CPU power states. * ``pm/device.h`` is no longer included by ``device.h``, since the device API no longer depends on the PM API. * Added support for power domains. Power domains are implemented as simple devices and use the existent PM API for resume and suspend, devices under a power domain are notified when it becomes active or suspended. * Added a new action :c:enum:`PM_DEVICE_ACTION_TURN_ON`. This action is used by power domains to notify devices when it becomes active. * Added new API (:c:func:`pm_device_state_lock`, :c:func:`pm_device_state_unlock` and :c:func:`pm_device_state_is_locked`) to lock a device pm state. When the device has its state locked, the kernel will no longer suspend and resume devices when the system goes to sleep and device runtime power management operations will fail. * :c:func:`pm_device_state_set` is deprecated in favor of utilizing :c:func:`pm_device_action_run`. * Proper multicore support. Devices are suspended only when the last active CPU. A cpu parameter was added to Policy and SoC interfaces. * Tracing * Support all syscalls being traced using the python syscall generator to introduce a tracing hook call. * IPC * Added IPC service support and RPMsg with static VRINGs backend HALs **** * STM32 * stm32cube/stm32wb and its lib: Upgraded to version V1.12.1 * stm32cube/stm32mp1: Upgraded to version V1.5.0 * stm32cube/stm32u5: Upgraded to version V1.0.2 * Added `GigaDevice HAL module <path_to_url`_ MCUboot ******* * Fixed serial recovery skipping on nrf5340. * Fixed issue which caused that progressive's erase feature was off although was selected by Kconfig (introduced by #42c985cead). * Added check of reset address in incoming image validation phase, see ``CONFIG_MCUBOOT_VERIFY_IMG_ADDRESS``. * Allow image header bigger than 1 KB for encrypted images. * Support Mbed TLS 3.0. * stm32: watchdog support. * many documentation improvements. * Fixed deadlock on cryptolib selectors in Kconfig. * Fixed support for single application slot with serial recovery. * Added various hooks to be able to change how image data is accessed, see ``CONFIG_BOOT_IMAGE_ACCESS_HOOKS``. * Added custom commands support in serial recovery (PERUSER_MGMT_GROUP): storage erase ``CONFIG_BOOT_MGMT_CUSTOM_STORAGE_ERASE``, custom image status ``CONFIG_BOOT_MGMT_CUSTOM_IMG_LIST``. * Added support for direct image upload, see ``CONFIG_MCUBOOT_SERIAL_DIRECT_IMAGE_UPLOAD`` in serial recovery. Trusted Firmware-m ****************** * Updated TF-M to 1.5.0 release, with a handful of additional cherry-picked commits. Documentation ************* * A new theme is used by the Doxygen HTML pages. It is based on `doxygen-awesome-css <path_to_url`_ theme. Tests and Samples ***************** * Drivers: clock_control: Added test suite for stm32 (u5, h7).

```restructuredtext :orphan: .. _zephyr_1.10: Zephyr Kernel 1.10.0 ##################### We are pleased to announce the release of Zephyr kernel version 1.10.0. Major enhancements with this release include: * Initial alpha-quality thread-level memory protection on x86, userspace and memory domains * Major overhaul to the build system and a switch from Kbuild to CMake. * Newtron Flash Filesystem (NFFS) Support * Increased testsuite coverage and migrated majority of testcases to use ztest * Integration with MCUBOOT Bootloader * Additional SoC, platform and driver support for many of the already supported platforms. The following sections provide detailed lists of changes by component. Kernel ****** * Remove deprecated k_mem_pool_defrag code * Initial alpha-quality thread-level memory protection on x86, userspace and memory domains: * Same kernel & driver APIs for kernel and user mode threads * System calls for privilege elevation * Stack overflow protection * Kernel object and device driver permission tracking * Simple app vs. kernel memory separation * Memory domain APIs for fine-tuning memory region permissions * Stack memory protection from other threads * Add the following application-facing memory domain APIs: * k_mem_domain_init() - to initialize a memory domain * k_mem_domain_destroy() - to destroy a memory domain * k_mem_domain_add_partition() - to add a partition into a domain * k_mem_domain_remove_partition() - to remove a partition from a domain * k_mem_domain_add_thread() - to add a thread into a domain * k_mem_domain_remove_thread() - to remove a thread from a domain * add k_calloc() which uses kernel heap to implement traditional calloc() semantics. * Introduce object validation mechanism: All system calls made from userspace, which involve pointers to kernel objects (including device drivers), will need to have those pointers validated; userspace must never be able to crash the kernel by passing it garbage. Architectures ************* * nrf52: Add support for LOW_POWER state and SYSTEM_OFF * Architecture specific memory domain APIs added * Tickless Kernel Implementation for Xtensa * Added support for the following ARM SoCs: * NXP i.MX RT1052 * Silabs EFM32WG * STM F0 * TI MSP432P4xx Boards ****** * Jailhouse port: The port will enable Zephyr to run as a guest OS on x86-64 systems. It comes with a test on QEMU to validate that, thus this new board introduction. * Power Management for nrf52 series SOC * Added support for the following ARM boards: * 96b_neonkey * efm32wg_stk3800 * mimxrt1050_evk * msp_exp432p401r_launchxl * nucleo_f030r8 * nucleo_f091rc * stm32f411e_disco * stm32f412g_disco * stm32l476g_disco * usb_kw24d512 Drivers and Sensors ******************* * timer: Add Support for TICKLESS KERNEL in xtensa_sys_timer * Rename ``random`` to ``entropy`` * Add Atmel SAM I2S (SSC) driver * Add Atmel SAM DMA (XDMAC) driver * Add plantower PMS7003 Driver * Add Altera shim driver for JTAG UART soft IP * Add Altera shim driver for timer soft IP * Introduce mcux ccm driver * Introduce mcux igpio shim driver Networking ********** * HTTP API changed to use net-app API. Old HTTP API is deprecated. * Loopback network interface support added. This is used in testing only. * LWM2M multi-fragment network packet support added. * New CoAP library implementation, supporting longer network packets. * Deprecated ZoAP library. * mDNS (multicast DNS) support added. * SNTP (Simple Network Time Protocol) client library added. * Various fixes for: TCP, RPL, ARP, DNS, LWM2M, Ethernet, net-app API, Network shell, and BSD socket API * Network management API fixes. * Networking sample application fixes. * 6lo IPv6 header compression fixes. * IEEE 802.15.4 generic fixes. * IEEE 802.15.4 mcr20a driver fixes. * IEEE 802.15.4 kw41z driver fixes. * IEEE 802.15.4 nrf5 driver fixes. Bluetooth ********* * Multiple qualification-related fixes for Bluetooth Mesh * Support for Bluetooth Mesh Friend Node role * Support for Bluetooth Mesh Foundation Client Models * New Bluetooth Mesh shell module and test application * Support for PA/LNA amplifiers in the BLE Controller * Support for additional VS commands in the BLE Controller * Multiple stability fixes for the BLE Controller Build and Infrastructure ************************ * The Zephyr project has migrated to CMake, an important step in a larger effort to make Zephyr easier to use for application developers working on different platforms with different development environment needs. This change retains Kconfig as-is, and replaces all Makefiles with corresponding CMakeLists.txt. The DSL-like Make language that KBuild offers is replaced by a set of CMake extensions that provide either simple one-to-one translations of KBuild features or introduce new concepts that replace KBuild concepts. Please re-read the Getting Started guide (path_to_url with updated instructions for setting up and developing on your host-OS. You will need to port your own out-of-tree scripts and Makefiles to CMake. Libraries / Subsystems *********************** * The implementation for sys_rand32_get() function has been moved to a new "random" subsystem. There are new implementations for this function, one based in the Xoroshift128+ PRNG (using a hardware number generator to seed), and another that obtains random numbers directly from a hardware number generator driver. Hardware number generator drivers have been moved to a "drivers/entropy" directory; these drivers only expose the interface provided by include/entropy.h. * TinyCrypt updated to version 0.2.8 HALs **** * Add Altera HAL for support NIOS-II boards * Add mcux 2.3.0 for mimxrt1051 and mimxrt1052 * stm32cube: HAL/LL static library for stm32f0xx v.1.9. * Add support for STM32 family USB driver * Add Silabs Gecko SDK for EFM32WG SoCs * Simplelink: Update cc32xx SDK to version 1.50.00.06 Documentation ************* * Missing API documentation caused by doxygen subgroups and missing Sphinx directives now included. * Note added to all released doc pages mentioning more current content could be available from the master branch version of the documentation. * Documentation updated to use CMake (vs. Make) in all examples, and using a new Sphinx extension to keep examples consistent. * Getting Started Guide material updated to include CMake dependencies and build instructions required for version 1.10. * Instead of hiding all expected warnings from the document build process (there are some known doxygen/sphinx issues), the build now outputs all warnings, and then reports if any new/unexpected warnings or errors were detected. * Obsolete V1 to V2 porting material removed. * Continued updates to documentation for new board support, new samples, and new features. * Integration of documentation with new zephyrproject.org website. * Documentation moved to docs.zephyrproject.org site (with redirection from zephyrproject.org/doc) Tests and Samples ***************** * Benchmarking: cleanup of the benchmarking code * Add userspace protection tests * Move all tests to ztest and cleanup coding style and formatting Issue Related Items ******************* These GitHub issues were addressed since the previous 1.9.0 tagged release: .. comment List derived from Jira/GitHub Issue query: ... * :github:`779` -

```restructuredtext .. _zephyr_1.7: Zephyr Kernel 1.7.0 #################### We are pleased to announce the release of Zephyr kernel version 1.7.0. This release continues refinement of the unified kernel introduced with the 1.6.0 kernel release, simplifying the overall Zephyr architecture and programming interfaces. This is the last release that will support the deprecated legacy nano- and micro-kernel APIs found in the 1.5.0 release and earlier. This release introduces a new native IP stack, replacing the legacy uIP stack, maintaining the legacy functionality, adding additional capabilities, and allowing future improvements. We have introduced support for the RISC V and Xtensa architectures and now support 6 architectures in total. Device tree support for ARM based boards added. The initial device tree support includes flash/sram base address and UART devices. Board support includes NXP Kinetis based SoCs, ARM Beetle, TI CC3200 LaunchXL, and STML32L476 based SoCs. Plan is to add support for other architectures and expand device support in upcoming Zephyr releases. The following sections provide a detailed list of changes, by component, since kernel version 1.6.0. Kernel ****** * Introduction of k_poll API: k_poll() is similar to the POSIX poll() API in spirit in that it allows a single thread to monitor multiple events without actively polling them, but rather pending for one or more to become ready. * Optimized memory use of some thread fields * Remove usage of micro/nano kernel terminology from kernel code and introduced a legacy option to enable/disable legacy APIs. (using legacy.h) Architectures ************* * ARM: Added support for device tree * ARM: Fixed exception priority access on Cortex M0(+) * ARM: Refactored to use CMSIS Boards ****** * Added ARM MPS2_AN385 board * Added Atmel SAM E70 Xplained board * Added Nordic pca10056 PDK board * Added NXP FRDM-KW41Z board * Added ST Nucleo-F334R8, Nucleo-L476G, STM3210C-EVAL, and STM32373C-EVAL boards * Added Panther and tinyTILE boards, based on Quark SE C1000 and Intel Curie * Added support for Zedboard Pulpino, a RISC V based board * Added Qemu target for RISC V and a simulator target for the Xtensa architecture. Drivers and Sensors ******************* * Added Atmel SAM pmc, gpio, uart, and ethernet drivers * Added STM32F3x clock, flash, gpio, pinmux drivers * Added stm32cube pwm and clock drivers * Added cc3200 gpio driver * Added mcr20a ieee802154 driver * Added mcux pinmux, gpio, uart, and spi drivers * Added Beetle clock control and watchdog drivers Networking ********** This version removes the legacy uIP stack and introduces a new native IP stack. Because of this there is lot of changes in the code base. The native IP stack will support the same functionality as the legacy IP stack found in 1.6, and add new networking features which are described below. * IP stack code is moved to subsys/net/ip directory. * IP stack supports both IPv6 and IPv4, and they can be enabled simultaneously. * Multiple network technologies like Bluetooth IPSP and IEEE 802.15.4 can be enabled simultaneously. No routing functionality is provided by IP stack between enabled network technologies, applications need to decide where to send the network packets. * Network technologies are abstracted in IP layer 2 (L2) and presented to rest of the system as network interfaces. There exists L2 driver for Ethernet, Bluetooth and IEEE 802.15.4. * Created Bluetooth Internet Protocol Support Profile (IPSP) support. It will provide IPv6 connection over Bluetooth connection oriented channel (L2CAP). * Created DHCPv4 support. * Created CoAP implementation called ZoAP which replaces uIP based one. * Updated 6Lo implementation to support both Bluetooth and IEEE 802.15.4 * Created application API (net_context) for creating connections and transferring data to external systems. * Added sample application (wpanusb) for exporting IEEE 802.15.4 radio over USB to external operating systems like Linux. * Added DNS client library. * Updated TCP implementation. * Created MQTT publisher support. * Created network test generator (zperf). * Created telnet console support. * Created IRC client sample application. * Created HTTP server and client sample applications. * Created net-shell module for interacting with network sub-system. * Created ieee15_4 shell module for dedicated interaction with IEEE 802.15.4 Soft MAC. * Created network management API for generic network settings request as well as a network event notification system (sender/listener). * Redesigned buffer & pool allocation API. Bluetooth ********* * Redesigned buffer pools for smaller memory consumption * Redesigned thread model for smaller memory consumption * Utilized new k_poll API to consolidate all TX threads into a single one * Added more SDP functionality * Improved RFCOMM support * Reduced latencies in the Controller * Added SPI HCI driver Libraries ********* * Updated mbedTLS library * Updated TinyCrypt to version 0.2.5 HALs **** * Updated FAT FS to rev 0.12b * Updated Nordic MDK header files * Updated QMSI to 1.4 RC3 * Imported Atmel SDK (ASF) for SAM E70 and SAM3X * Imported Nordic SDK HAL and 802.15.4 radio driver * Renamed NXP KSDK to MCUX * Imported NXP MCUX for KW41Z * Imported Segger J-Link RTT library * Imported stm32cube for F4 and L4 Documentation ************* * General improvements and additions to kernel component docs * Moved supported board information back to the website site. * New website documentation theme to go with the new zephyrproject.org site. * New local-content generation theme (read-the-docs) * General spelling checks and organizational improvements. * Site-wide glossary added. * Porting guides added. * Sample README files converted to documents included in the website. * Improved consistency of :ref:`boards` and :ref:`samples-and-demos`.

Use new functions that utilize eDTS info such as dt_node_reg_addr. See :zephyr_file:`scripts/kconfig/kconfigfunctions.py` for details. * Deprecated direct use of the ``DT_`` Kconfig symbols from the generated ``generated_dts_board.conf``. This was done to have a single source of Kconfig symbols coming from only Kconfig (additionally the build should be slightly faster). For Kconfig files we should utilize functions from :zephyr_file:`scripts/kconfig/kconfigfunctions.py`. See :ref:`kconfig-functions` for usage details. For sanitycheck yaml usage we should utilize functions from :zephyr_file:`scripts/sanity_chk/expr_parser.py`. Its possible that a new function might be required for a particular use pattern that isn't currently supported. * Various parts of the binding format have been simplified. The format is better documented now too. Libraries / Subsystems *********************** * Random * Add cryptographically secure random functions * Add bulk fill random functions HALs **** * HALs are now moved out of the main tree as external modules and reside in their own standalone repositories. Documentation ************* * A new Getting Started Guide simplifies and streamlines the "out of box" experience for developers, from setting up their development environment through running the blinky sample. * Many additions and updates to architecture, build, and process docs including sanity check, board porting, Bluetooth, scheduling, timing, peripherals, configuration, and user mode. * Documentation for new boards and samples. * Improvements and clarity of API documentation. Tests and Samples ***************** * We have implemented additional tests and significantly expanded the amount of test cases in existing tests to increase code coverage.

An overview of the changes required or recommended when migrating your application from Zephyr v3.5.0 to Zephyr v3.6.0 can be found in the separate :ref:`migration guide<migration_3.6>`. The following sections provide detailed lists of changes by component. Security Vulnerability Related ****************************** The following CVEs are addressed by this release: More detailed information can be found in: path_to_url * CVE-2023-5779 `Zephyr project bug tracker GHSA-7cmj-963q-jj47 <path_to_url`_ * CVE-2023-6249 `Zephyr project bug tracker GHSA-32f5-3p9h-2rqc <path_to_url`_ * CVE-2023-6749 `Zephyr project bug tracker GHSA-757h-rw37-66hw <path_to_url`_ * CVE-2023-6881 `Zephyr project bug tracker GHSA-mh67-4h3q-p437 <path_to_url`_ * CVE-2023-7060: Under embargo until 2024-03-14 * CVE-2024-1638 `Zephyr project bug tracker GHSA-p6f3-f63q-5mc2 <path_to_url`_ Architectures ************* * ARC * Enabled hardware prefetcher and shared cluster cache (SCM - Shared Cluster Memory) for ARCv3 processors (HS5x & HS6x). * Disabled Thread-local Storage support for platforms with two or more register banks. * Fixed unstable work of application built with MetaWare toolchain for hardware platforms (garbage in .device_states section). * ARM * MPU regions are now always cleared before initialization. * Standardized on :c:func:`arch_secondary_cpu_init` to provide consistency across all architectures. * Renamed :c:func:`z_arm_prep_c` as :c:func:`z_prep_c` to provide consistency across all architectures. * Renamed the exception header to be consistent across all architectures. * GDB stubs added (currently only supports Zynq-7000). * Added support for custom interrupt controllers using :kconfig:option:`CONFIG_ARM_CUSTOM_INTERRUPT_CONTROLLER`. * MMU and MPU initialization moved to :c:func:`z_prep_c` for Cortex-A and Cortex-R to enable initialization by individual cores. * Common Cortex-M MPU code moved to ``arch/arm/core/mpu``. * Xtensa * Removed the unused Kconfig option ``CONFIG_XTENSA_NO_IPC``. * Added userspace support via MMU. Bluetooth ********* * Audio * Changed ``bt_bap_scan_delegator_subgroup`` to :c:struct:`bt_bap_bass_subgroup` and made it independent of :kconfig:option:`CONFIG_BT_BAP_SCAN_DELEGATOR`. * Modified :c:func:`bt_bap_stream_send` to no longer take a timestamp as parameter, and added :c:func:`bt_bap_stream_send_ts` that does. * Modified :c:func:`bt_cap_stream_send` to no longer take a timestamp as parameter, and added :c:func:`bt_cap_stream_send_ts` that does. * Assigned number values have been moved from :file:`include/zephyr/bluetooth/audio/lc3.h` to :file:`include/zephyr/bluetooth/audio/audio.h` and the ``LC3`` infix have been removed. * The CAP initiator APIs have been streamlined and follow the same parameter pattern. * Added Kconfig options to make MCC functionality optional to reduce memory usage for simple clients. * Added CAP Commander change volume and change volume offset. * Added proper support for doing decoding in the application instead of in the controller by modifying how the ISO data path is configured. * Added :c:func:`bt_csip_set_member_unregister` to unregister a CSIS instance. * Added helper functions to get and set assigned number values in codec configuration and codec capabilities. * Added support for the new mono audio location. * Added ISO state callbacks for streams so the user knows the state of the CIS. * Added :c:func:`bt_pacs_set_available_contexts_for_conn` to set available context per connection. * Refactored the :c:struct:`bt_bap_base` to be an abstract struct with new helper functions, so that Zephyr supports all BASEs regardless of the size. * Host * Added ``recycled()`` callback to :c:struct:`bt_conn_cb`, which notifies listeners when a connection object has been freed, so it can be utilized for different purposes. No guarantees are made to what listener will be granted the object, as only the first claim is served. * Modified :c:func:`bt_iso_chan_send` to no longer take a timestamp as parameter, and added :c:func:`bt_iso_chan_send_ts` that does. * Mesh * Added the delayable messages functionality to apply random delays for the transmitted responses on the Access layer. The functionality is enabled by the :kconfig:option:`CONFIG_BT_MESH_ACCESS_DELAYABLE_MSG` Kconfig option. * The Bluetooth Mesh protocol 1.1 is now supported by default. * Controller * Added deinit implementation for ESP32 controller. * HCI Driver * Split ST HCI SPI Bluetooth driver from the Zephyr one to provide more features based on ST SPI protocols V1 and V2. As a result, :dtcompatible:`st,hci-spi-v1` and :dtcompatible:`st,hci-spi-v2` were introduced. Boards & SoC Support ******************** * Added support for these SoC series: * Added support for Renesas R-Car Gen4 series. * Added support for STM32F303xB SoC variants. * Added support for STM32H7B0xx SoC variants. * Added support for STM32L010xx SoC variants. * Added support for STM32L081xx SoC variants. * Added support for STM32U5A9xx SoC variants. * Added support for NXP S32K1 devices. * Added support for NXP IMX8ULP SoC. * Added support for NXP MIMXRT595 DSP core. * Made these changes in other SoC series: * Nordic SoCs now imply :kconfig:option:`CONFIG_XIP` instead of selecting it. This allows for creating RAM-based applications by disabling it. * BLE is now supported on STM32WBA series. * xtensa: imx8: Split the generic i.MX8 SoC into i.MX8QXP and i.MX8QM. * LPC55xxx: Fixed the system hardware clock cycle rate. * Added support for these ARM boards: * Added support for Adafruit QTPy RP2040 board: ``adafruit_qt_py_rp2040``. * Added support for FANKE FK7B0M1-VBT6 board: ``fk7b0m1_vbt6``. * Added support for Renesas R-Car Spider board CR52: ``rcar_spider_cr52``. * Added support for ST Nucleo F722ZE board: ``nucleo_f722ze``. * Added support for ST STM32H750B Discovery Kit: ``stm32h750b_dk``. * Added support for ST STM32L4R9I Discovery board: ``stm32l4r9i_disco``. * Added support for ST STM32U5A9J-DK discovery kit: ``stm32u5a9j_dk``. * Added support for ST Nucleo WBA55CG board: ``nucleo_wba55cg``. * Added support for ST STM32WB5MM-DK Discovery board: ``stm32wb5mm_dk``. * Added support for Wiznet W5500 Evaluation Pico board: ``w5500_evb_pico``. * Added support for ADI boards: ``adi_sdp_k1``, ``adi_eval_adin1110ebz``, ``adi_eval_adin2111ebz``. * Added support for NXP UCANS32K1SIC board: ``ucans32k1sic``. * Added support for this RISC-V board: * Added Lilygo TTGO T8-C3 board: ``ttgo_t8c3``. * Added support for these Xtensa boards: * Added support for NXP iMX8ULP board: ``nxp_adsp_imx8ulp``. * Added Heltec Wireless Stick Lite (V3) board: ``heltec_wireless_stick_lite_v3``. * Added KINCONY-KC868-A32 board: ``kincony_kc868_a32``. * Added Lolin ESP32-S2 Mini board: ``esp32s2_lolin_mini``. * Added Lilygo TTGO LoRa32 board: ``ttgo_lora32``. * Added M5Stack AtomS3 board: ``m5stack_atoms3``. * Added M5Stack AtomS3-Lite board: ``m5stack_atoms3_lite``. * Added M5Stack StampS3 board: ``m5stack_stamps3``. * Made these changes for ARM boards: * Added support for low power on G1120B0MIPI using RT595. * Added support for lpspi, lpi2c on NXP board: ``mimx93_evk_a55``. * Fixed partition naming on ``lpcxpresso55s69`` to use the standard slot naming used by TFM-enabled Zephyr platforms. * Enabled support for linkserver debugger on ``frdm_kl25z``, ``mimxrt1015_evk``, ``mimxrt1020_evk``, ``mimxrt1050_evk``, ``mimxrt685_evk``, ``frdm_k64f``. * Switched MCUBoot FW Update mode on NXP boards from Swap & Scratch to Swap & Move. * Made these changes for RISC-V boards: * Enabled ADC support on ``longan_nano``. * Made these changes for native/POSIX boards: * The :ref:`simulated nrf5340 targets<nrf5340bsim>` now include the IPC and MUTEX peripherals, and support OpenAMP to communicate between the cores. It is now possible to run the BLE controller or 802.15.4 driver in the net core, and application and BT host in the app core. * The nrf_bsim simulated targets now include models of the UART peripheral. It is now possible to connect a :ref:`nrf52_bsim<nrf52_bsim>` UART to another, or a UART in loopback, utilizing both the new and legacy nRFx UART drivers, in any mode. For the native simulator based targets it is now possible to set via Kconfig command line options which will be handled by the executable as if they were provided from the invoking shell. * For all native boards, the native logger backend will now also be used even if the UART is enabled. * Several bugfixes and other minor additions to the nRF5x HW models. * Multiple documentation updates and fixes for all native boards. * Added support for these following shields: * Added support for M5Stack-Core2 base: ``m5stack_core2_ext``. * Added support for MikroElektronika ACCEL 13 Click: ``mikroe_accel13_click``. * Added support for Waveshare Pico UPS-B: ``waveshare_pico_ups_b``. * Added support for X-NUCLEO-BNRG2A1: BLE expansion board: ``x_nucleo_bnrg2a1``. * Added support for X-NUCLEO-IKS4A1: MEMS Inertial and Environmental Multi sensor: ``x_nucleo_iks4a1``.

This change includes interrupt script generator rebuilding and adds the following Kconfig options: - :kconfig:option:`CONFIG_ISR_TABLES_LOCAL_DECLARATION`: LTO compatible interrupt tables parser - :kconfig:option:`CONFIG_LTO`: Enable Link Time Optimization Currently the LTO compatible interrupt tables parser is only supported by ARM architectures and GCC compiler/linker. See pull request :github:`66392` for details. * Dropped the ``COMPAT_INCLUDES`` option. It was unused since Zephyr v3.0. * Fixed an issue whereby board revision ``0`` did not include overlay files for that revision. * Added ``PRE_IMAGE_CMAKE`` and ``POST_IMAGE_CMAKE`` hooks to sysbuild modules, which allows for modules to run code after and before each image's cmake invocation. * Added :kconfig:option:`CONFIG_ROM_END_OFFSET` option which allows reducing the size of an image. This is intended for use with firmware signing scripts which add additional data to the end of images outside of the build itself. * Added MCUboot image size reduction to sysbuild images which include MCUboot. This prevents issues with building firmware images that are too large for MCUboot to swap. * Deprecated :kconfig:option:`CONFIG_BOOTLOADER_SRAM_SIZE`. Users of this should transition to having RAM set up properly in their board devicetree files. * Fixed an issue whereby shields were processed in order of the root they resided in rather than the order they were supplied to cmake in. * Fixed an issue whereby using some shields with sysbuild would cause a cmake Kconfig error. * Fixed an issue where the macros ``_POSIX_C_SOURCE`` and ``_XOPEN_SOURCE`` would be defined globally when building with Picolibc or for the native (``ARCH_POSIX``) targets. After this change users may need to define them for their own applications or libraries. * Added support for sysbuild setting a signing script (``SIGNING_SCRIPT``). See :ref:`west-extending-signing` for details. * Added support for ``FILE_SUFFIX`` in the build system which allows for adding suffixes to application Kconfig fragment file names and devicetree overlay file names. See :ref:`application-file-suffixes` and :ref:`sysbuild_file_suffixes` for details. * Deprecated ``CONF_FILE`` ``prj_<build>.conf`` build type. * Added `-Wdouble-promotion` as a default warning when compiling to warn developers with single-precision floats easily being promoted to double-precision. Drivers and Sensors ******************* * ADC * Power Management for ADC is now supported on STM32 devices. * STM32 ADC driver now supports mixing shared and separate IRQs (for instance on STM32G473 which has 5 ADCs, ADC1 and ADC2 share one IRQ while ADC3, ADC4 and ADC5 each have unique IRQs). Enabling all instances in the same application is not possible on such devices as of now. * Auxiliary Display * Added Sparkfun SerLCD driver. * Audio * Added a driver :file:`drivers/audio/dmic_mcux.c` for NXP DMIC peripheral.

Logging changes, RMII clock fixes, GPIO pin fixes. * Added a driver :file:`drivers/ethernet/eth_nxp_enet.c` for NXP ENET which is a rework of the old driver :file:`drivers/ethernet/eth_mcux.c`. The old driver became unmaintainable due to fundamental problems with the lack of PHY abstraction. The new driver is still experimental and requires maturation. Eventually the old driver will be deprecated and this new driver will be supported instead. * Flash * Redesigned the Atmel SAM controller to fully utilize flash page layout. * ``spi_nor`` driver now sleeps between polls in ``spi_nor_wait_until_ready``. If this is not desired (For example due to ROM constraints in a bootloader), :kconfig:option:`CONFIG_SPI_NOR_SLEEP_WHILE_WAITING_UNTIL_READY` can be disabled. * Flash readout protection configuration was added on STM32G4 and STM32L4 series. * ``nordic_qspi_nor`` driver now supports user-configurable QSPI timeout with :kconfig:option:`CONFIG_NORDIC_QSPI_NOR_TIMEOUT_MS`. * GNSS * Added GNSS device driver API and subsystem for parsing and publishing location, datetime, and satellite information, enabled by :kconfig:option:`CONFIG_GNSS` and :kconfig:option:`CONFIG_GNSS_SATELLITES`.

It also allows more reliable communication with UART devices sensitive to variation of inter-frames delays. In RX, FIFO reduces overrun occurrences. * SPI * On STM32H7 devices, ``fifo-enable`` property allows using SPI block FIFO. This feature is still experimental and requires maturation. * On STM32 devices impacted by BSY bit erratum, a workaround was implemented. * USB * On STM2G0 devices, property ``crs-usb-sof`` in ``clk_hsi48`` node enables support for Clock Recovery System, allowing a more stable HSI48 clock and hence resilient USB connection. * On compatible STM32 devices, isochronous endpoints are now functional thanks to the use of double buffering. * Added new UDC driver for DWC2 controller. * Added support for Nuvoton NuMaker series USBD controllers. * W1 * Added 1-Wire GPIO master driver.

It now returns success. * Fixed MCUmgr UDP transport structs being statically initialised. This results in about a ~5KiB flash saving. * Fixed an issue in MCUmgr which would cause a user data buffer overflow if the UDP transport was enabled on IPv4 only but IPv6 support was enabled in the kernel. * Implemented datetime functionality in MCUmgr OS management group. This makes use of the RTC driver API. * Fixed an issue in MCUmgr console UART input whereby the FIFO would be read outside of an ISR, which is not supported in the next USB stack. * Fixed an issue whereby the ``mcuboot erase`` DFU shell command could be used to erase the MCUboot or currently running application slot. * Fixed an issue whereby messages that were too large to be sent over the UDP transport would wrongly return :c:enumerator:`MGMT_ERR_EINVAL` instead of :c:enumerator:`MGMT_ERR_EMSGSIZE`. * Fixed an issue where confirming an image in Direct XIP mode would always confirm the image in the primary slot even when executing from the secondary slot. Now the currently active image is always confirmed. * Added support for retrieving registered command groups, to support registering and deregistering default command groups at runtime, allowing an application to support multiple implementations for the same command group. * Fixed an issue in MCUmgr FS management whereby the semaphore lock would not be given if an error was returned, leading to a possible deadlock. * Added support for custom payload MCUmgr handlers. This can be enabled with :kconfig:option:`CONFIG_MCUMGR_MGMT_CUSTOM_PAYLOAD`. * Fixed an issue in MCUmgr image management whereby an error would be returned if a command was sent to erase the slot which was already erased. * Added support for image slot size checking to ensure an update can be utilised by MCUboot. This can be performed by using sysbuild when building both application and MCUboot by enabling :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_TOO_LARGE_SYSBUILD` or by use of bootloader information sharing from MCUboot by enabling :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_TOO_LARGE_BOOTLOADER_INFO`. * Logging * Added an option to remove string literals from the binary when dictionary-based logging is used. * Optimized the most common logging messages (strings with up to 2 numeric arguments). Optimization is done for code size (significant gain seen on riscv32) and performance. * Extended logging frontend API to optionally implement dedicated functions for optimized messages. Optional API is enabled by :kconfig:option:`CONFIG_LOG_FRONTEND_OPT_API`. * Added support for runtime message filtering for the logging frontend. * Added option to support multiple instances of the UART logging backend. * Fixed userspace issue for :c:func:`printk` when :kconfig:option:`CONFIG_LOG_PRINTK` is enabled. * Added compile time detection of logging messages that use character pointers for ``%p``. It must be avoided when dictionary-based logging is used and strings are stripped from the binary. When an erroneous case is detected, the user message is replaced with an error message that suggests pointer casting must be added. * Removed remaining references to v2 logging. Renamed :c:func:`log2_generic` to :c:func:`log_generic`. * Modem modules * Added ``TRANSMIT_IDLE`` event to the ``modem_pipe`` module which notifies the user of the pipe that the backend has transmitted all bytes placed in its buffer using :c:func:`modem_pipe_transmit()`. The event greatly increases the efficiency of transmitting large quantities of data if used to dynamically manage the delay between calls to :c:func:`modem_pipe_transmit()`. * Implemented ``TRANSMIT_IDLE`` event in all modem backends. * Extended all modem modules to utilize the ``TRANSMIT_IDLE`` event to dynamically manage the delay between calls to :c:func:`modem_pipe_transmit()`. This addition reduced the utilization of the system workqueue while transmitting large, continuous quantities of data, by 86%, while only reducing the throughput by 12%. This optimization additionally allows lower priority threads, like the deferred logging thread, to run during the transmission (it was blocked by the relentless, continuous calls to :c:func:`modem_pipe_transmit()`). * Improved ``modem_pipe`` event dispatching. The ``modem_pipe`` module now invokes the ``RECEIVE_READY`` event every time the pipe is attached using :c:func:`modem_pipe_attach()` if it has data ready to be read, and always invokes ``TRANSMIT_IDLE`` when the pipe is either opened or attached. This ensures event driven users of the modem pipe module can rely solely on the events to start read/transmit work. A test suite has been added to complement the improvements. * Extended ``modem_cmux`` module to support acting both as DTE (user application) and DCE (modem). With this addition, two Zephyr applications can communicate with each other through their respective ``modem_cmux`` instances. * Picolibc * Updated to version 1.8.6. This removes the :c:macro:`_POSIX_C_SOURCE` definition from the build system, so applications will need to add this if they use APIs outside of the Zephyr requirements. * Added new :c:func:`printf` modes, :kconfig:option:`CONFIG_PICOLIBC_IO_LONG_LONG` and :kconfig:option:`CONFIG_PICOLIBC_IO_MINIMAL`. These provide applications with finer grained control over the level of support provided by the library to control text space usage. By default, the correct level of support is selected based upon other configuration parameters. * Added :kconfig:option:`CONFIG_PICOLIBC_ASSERT_VERBOSE`. This option, which is false by default, controls whether the :c:func:`assert` function displays verbose information, including the file name, line number, function name and failing expression text, when the assertion fails. Leaving this disabled saves text space. * :kconfig:option:`CONFIG_THREAD_LOCAL_STORAGE` can now be disabled while using Picolibc. This is very helpful in diagnosing issues when using Picolibc as those are often caused by enabling TLS and not caused by using the library itself. * Numerous improvements in the library including code-size reductions in areas like printf and ctype and various fixes in the math library. * Power management * Introduced Atmel SAM SUPC functions to allow wakeup sources and poweroff. * STM32F4 devices now support stop mode thanks to the use of a RTC based idle timer which keeps track of tick evolution while cortex systick is off. * :c:func:`pm_device_runtime_put_async()` got a parameter to specify a minimum delay to the operation. This is useful to avoid multiple states transitions when a device is used. * Devices that don't need to block when suspending or resuming can now be defined as ISR safe (``PM_DEVICE_ISR_SAFE``). For those devices, Zephyr is able to reduce RAM consumption and runtime device power management can be safely used from interrupts. * Optimizations in device runtime power management. :c:func:`pm_device_runtime_get` and :c:func:`pm_device_runtime_put` no longer wait for a pending operation to be concluded if it is still in the work queue. In this case, the pending work is just canceled and the device state updated. * The Kconfig options below were added to customize the initialization priority of different power domains. * :kconfig:option:`CONFIG_POWER_DOMAIN_GPIO_INIT_PRIORITY` * :kconfig:option:`CONFIG_POWER_DOMAIN_GPIO_MONITOR_INIT_PRIORITY` * :kconfig:option:`CONFIG_POWER_DOMAIN_INTEL_ADSP_INIT_PRIORITY` * Crypto * Mbed TLS updated to 3.5.2. Full release notes can be found in: path_to_url * Retention * Fixed issue whereby :kconfig:option:`CONFIG_RETENTION_BUFFER_SIZE` values over 256 would cause an infinite loop due to use of 8-bit variables. * SD * Added support for SDIO devices. * Storage * File systems: LittleFS module has been updated to version 2.8.1. * Following Flash Map API macros, marked in 3.2 as deprecated, have been removed: ``FLASH_AREA_ID``, ``FLASH_AREA_OFFSET``, ``FLASH_AREA_SIZE``, ``FLASH_AREA_LABEL_EXISTS`` and ``FLASH_AREA_DEVICE``. * POSIX API * Completed support for ``POSIX_THREADS_EXT``, ``XSI_THREADS_EXT``, ``POSIX_CLOCK_SELECTION``, and ``POSIX_SEMAPHORES`` Option Groups. * Completed support for ``_POSIX_MESSAGE_PASSING`` and ``_POSIX_PRIORITY_SCHEDULING`` Options. * Fixed Coverity-CID 211585, 334906, 334909, and 340851. * Improved structure and accuracy of POSIX documentation. * Improved navigation and organization of POSIX Kconfig options. * Added support to allocate and free stacks up to 8 MB with pthread_attr_t. * Added support for deferred and asynchronous thread cancellation. * Added dining philosophers sample application. * Added support for named semaphores. * Added a top-level ``posix`` command in the Zephyr shell. Zephyr shell utilities for the POSIX API can be added as subcommands (e.g. ``posix uname -a``) * Added support for async thread cancellation and ``SIGEV_THREAD``, ``CLOCK_REALTIME``. * Added compile-time-constant sysconf() implementation. * LoRa/LoRaWAN * Added LoRaWAN remote multicast support with :kconfig:option:`CONFIG_LORAWAN_REMOTE_MULTICAST` in preparation for OTA firmware upgrade support. * ZBus * Replaced mutexes with semaphores to lock channels and implement the Highest Locker Protocol (HLP) priority boost for the zbus operations. This feature avoids priority inversions and preemptions, making the VDED delivery process faster and more consistent. (:github:`63183`) * Fixed documentation for :c:func:`zbus_chan_add` and :c:func:`zbus_chan_rm` adding the timeout argument. (:github:`65544`) * Fixed warning when mixing C and C++ files using zbus. (:github:`65222`) * :c:macro:`ZBUS_CHANNEL_DEFINE` macro is now compatible with C++. (:github:`65196`) * Fixed parameter order of net buf pool fixed definition. (:github:`65039`) * Refactored the benchmark sample, adding message subscribers. (:github:`64524`) * Renamed ``CONFIG_ZBUS_MSG_SUBSCRIBER_NET_BUF_DYNAMIC`` and ``CONFIG_ZBUS_MSG_SUBSCRIBER_NET_BUF_STATIC`` to :kconfig:option:`CONFIG_ZBUS_MSG_SUBSCRIBER_BUF_ALLOC_DYNAMIC` and :kconfig:option:`CONFIG_ZBUS_MSG_SUBSCRIBER_BUF_ALLOC_STATIC`. (:github:`65632`) HALs **** * STM32 * Updated STM32F1 to cube version V1.8.5. * Updated STM32F7 to cube version V1.17.1. * Updated STM32H7 to cube version V1.11.1. * Updated STM32L4 to cube version V1.18.0. * Updated STM32U5 to cube version V1.4.0. * Updated STM32WBA to cube version V1.2.0. * Updated STM32WB to cube version V1.18.0. MCUboot ******* * Fixed compatible sector checking in bootutil. * Fixed Kconfig issue with saving encrypted TLVs not depending on encryption being enabled. * Fixed issue with missing condition check for applications in sysflash include file. * Fixed issue with single slot encrypted image listing support in boot_serial. * Fixed issue with allowing MBEDTLS Kconfig selection when tinycrypt is used. * Fixed missing response if echo command was disabled in boot_serial. * Fixed issue with USB configurations not generating usable images. * Added debug logging for boot status write in bootutil. * Added estimated image overhead size to cache in sysbuild. * Added firmware loader operating mode which allows for a dedicated secondary slot image that is used to update the primary image. * Added error if main thread is not pre-emptible when USB CDC serial recovery is enabled. * Added error if USB CDC and console are both enabled and set to the same device. * Removed the deprecated ``CONFIG_ZEPHYR_TRY_MASS_ERASE`` Kconfig option. * Updated zcbor to version 0.8.1 and re-generated boot_serial files. * Moved IO functions out of main to separate file. * Made ``align`` parameter of imgtool optional. * Added MCUBoot support for ``mimxrt1010_evk``, ``mimxrt1015_evk``, ``mimxrt1040_evk``, ``lpcxpresso55s06``, ``lpcxpresso55s16``, ``lpcxpresso55s28``, ``lpcxpresso55s36``, ``lpcxpresso55s69_cpu0``. * Added :kconfig:option:`CONFIG_MCUBOOT_IMGTOOL_OVERWRITE_ONLY` which passes the --overwrite-only option to imgtool to avoid adding the swap status area size when calculating overflow. It is used by non-swap update modes. * The MCUboot version in this release is version ``2.1.0+0-dev``. zcbor ***** zcbor has been updated from 0.7.0 to 0.8.1. Full release notes can be found at: path_to_url and path_to_url Highlights: * Addded support for unordered maps. * Performance improvements. * Naming improvements for generated code. * Bugfixes. LVGL **** LVGL has been updated from 8.3.7 to 8.3.11. Detailed release notes can be found at: path_to_url Additionally, the following changes in Zephyr were done: * Added the :dtcompatible:`zephyr,lvgl-keypad-input` compatible for keypad input. * Fixed issue with the Zephyr log levels not mapping properly to LVGL log levels. * Fixed issue where setting :kconfig:option:`CONFIG_LV_Z_FULL_REFRESH` did not set :kconfig:option:`CONFIG_LV_Z_VDB_SIZE` to 100 percent. Tests and Samples ***************** * :ref:`native_sim<native_sim>` has replaced :ref:`native_posix<native_posix>` as the default test platform. :ref:`native_posix<native_posix>` remains supported and used in testing but will be deprecated in a future release. * Bluetooth split stacks tests, where the BT host and controller are run in separate MCUs, are now run in CI based on the :ref:`nrf5340_bsim<nrf5340bsim>` targets. Several other runtime AMP tests based on these targets have been added to CI, including tests of OpenAMP, the mbox and IPC drivers/subsystem, and the logger multidomain functionality. * Runtime UART tests have been added to CI based on the :ref:`nrf52_bsim<nrf52_bsim>` target. These include tests of the nRFx UART driver and networked BT stack tests with the host and controller in separate devices communicating over the HCI UART driver. * Fixed an issue in :zephyr:code-sample:`smp-svr` sample whereby if USB was already initialised, application would fail to boot properly. * Added an LVGL sample :zephyr:code-sample:`lvgl-accelerometer-chart` showcasing displaying of live sensor data in a chart widget. * Added ESP32-S3 IPM support in :zephyr:code-sample:`ipm-esp32`. * Added ESP32 memory-mapped flash access sample in :zephyr:code-sample:`esp32-flash-memory-mapped`. * Added ESP32 PWM loopback test case. * Added support in the mbox sample for NXP boards ``MIMXRT1160-EVK``, ``MIMXRT1170-EVK``, ``MIMXRT1170-EVKB``, ``LPCXpresso55S69``. * Added a sample ``flexram-magic-addr`` for ``mimxrt11xx_cm7`` to show how to use flexram magic address functionality when using memc flexram driver. ```	/content/code_sandbox/doc/releases/release-notes-3.6.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	14,428
```restructuredtext :orphan: .. _migration_3.6: Migration guide to Zephyr v3.6.0 ################################ This document describes the changes required when migrating your application from Zephyr v3.5.0 to Zephyr v3.6.0. Any other changes (not directly related to migrating applications) can be found in the :ref:`release notes<zephyr_3.6>`. .. contents:: :local: :depth: 2 Build System ************ * The deprecated ``prj_<board>.conf`` Kconfig file support has been removed, projects that use this should switch to using board Kconfig fragments instead (``boards/<board>.conf``). * Until now ``_POSIX_C_SOURCE``, ``_XOPEN_SOURCE``, and ``_XOPEN_SOURCE_EXTENDED`` were defined globally when building for the native (``ARCH_POSIX``) targets, and ``_POSIX_C_SOURCE`` when building with PicolibC. Since this release, these are set only for the files that need them. If your library or application needed this, you may start getting an "implicit declaration" warning for functions whose prototypes are only exposed if one of these is defined. If so, you can fix it by defining the corresponding macro in your C source file before any include, or by adding the equivalent of ``target_compile_definitions(app PRIVATE _POSIX_C_SOURCE=200809L)`` to your application or ``zephyr_library_compile_definitions(_POSIX_C_SOURCE=200809L)`` to your library. * Build type by setting ``CONF_FILE`` to ``prj_<build>.conf`` is now deprecated, users should instead use the new ``-DFILE_SUFFIX`` feature :ref:`application-file-suffixes`. Kernel ****** * The system heap size and its availability is now determined by a ``K_HEAP_MEM_POOL_SIZE`` define instead of the :kconfig:option:`CONFIG_HEAP_MEM_POOL_SIZE` Kconfig option. Subsystems can specify their own custom system heap size requirements by specifying Kconfig options with the prefix ``CONFIG_HEAP_MEM_POOL_ADD_SIZE_``. The old Kconfig option still exists, but will be overridden if the custom requirements are larger. To force the old Kconfig option to be used, even when its value is less than the indicated custom requirements, a new :kconfig:option:`CONFIG_HEAP_MEM_POOL_IGNORE_MIN` option has been introduced (which defaults being disabled). * STM32H7 and STM32F7 should now activate the cache (Icache and Dcache) by setting explicitly the ``CONFIG_CACHE_MANAGEMENT`` to ``y``. Boards ****** * The deprecated Nordic SoC Kconfig option ``NRF_STORE_REBOOT_TYPE_GPREGRET`` has been removed, applications that use this should switch to using the :ref:`boot_mode_api` instead. * NXP: Enabled :ref:`linkserver<linkserver-debug-host-tools>` to be the default runner on the following NXP boards: ``mimxrt685_evk_cm33``, ``frdm_k64f``, ``mimxrt1050_evk``, ``frdm_kl25z``, ``mimxrt1020_evk``, ``mimxrt1015_evk`` Modules ******* Optional Modules ================ The following modules have been made optional and are not downloaded with `west update` by default anymore: * ``canopennode`` (:github:`64139`) To enable them again use the ``west config manifest.project-filter -- +<module name>`` command, or ``west config manifest.group-filter -- +optional`` to enable all optional modules, and then run ``west update`` again. MCUboot ======= * MCUboot's deprecated ``CONFIG_ZEPHYR_TRY_MASS_ERASE`` Kconfig option has been removed. If an erase is needed when flashing MCUboot, this should now be provided directly to the ``west`` command e.g. ``west flash --erase``. (:github:`64703`) zcbor ===== * If you have zcbor-generated code that relies on the zcbor libraries through Zephyr, you must regenerate the files using zcbor 0.8.1. Note that the names of generated types and members has been overhauled, so the code using the generated code must likely be changed. For example: * Leading single underscores and all double underscores are largely gone, * Names sometimes gain suffixes like ``_m`` or ``_l`` for disambiguation. * All enum (choice) names have now gained a ``_c`` suffix, so the enum name no longer matches the corresponding member name exactly (because this broke C++ namespace rules). * The function :c:func:`zcbor_new_state`, :c:func:`zcbor_new_decode_state` and the macro :c:macro:`ZCBOR_STATE_D` have gained new parameters related to decoding of unordered maps. Unless you are using that new functionality, these can all be set to NULL or 0. * The functions :c:func:`zcbor_bstr_put_term` and :c:func:`zcbor_tstr_put_term` have gained a new parameter ``maxlen``, referring to the maximum length of the parameter ``str``. This parameter is passed directly to :c:func:`strnlen` under the hood. * The function :c:func:`zcbor_tag_encode` has been renamed to :c:func:`zcbor_tag_put`. * Printing has been changed significantly, e.g. :c:func:`zcbor_print` is now called :c:func:`zcbor_log`, and :c:func:`zcbor_trace` with no parameters is gone, and in its place are :c:func:`zcbor_trace_file` and :c:func:`zcbor_trace`, both of which take a ``state`` parameter. Device Drivers and Devicetree ***************************** Devicetree Labels ================= * Various deprecated macros related to the deprecated devicetree label property were removed. These are listed in the following table. The table also provides replacements. However, if you are still using code like ``device_get_binding(DT_LABEL(node_id))``, consider replacing it with something like ``DEVICE_DT_GET(node_id)`` instead. The ``DEVICE_DT_GET()`` macro avoids run-time string comparisons, and is also safer because it will fail the build if the device does not exist. .. list-table:: :header-rows: 1 * - Removed macro - Replacement * - ``DT_GPIO_LABEL(node_id, gpio_pha)`` - ``DT_PROP(DT_GPIO_CTLR(node_id, gpio_pha), label)`` * - ``DT_GPIO_LABEL_BY_IDX(node_id, gpio_pha, idx)`` - ``DT_PROP(DT_GPIO_CTLR_BY_IDX(node_id, gpio_pha, idx), label)`` * - ``DT_INST_GPIO_LABEL(inst, gpio_pha)`` - ``DT_PROP(DT_GPIO_CTLR(DT_DRV_INST(inst), gpio_pha), label)`` * - ``DT_INST_GPIO_LABEL_BY_IDX(inst, gpio_pha, idx)`` - ``DT_PROP(DT_GPIO_CTLR_BY_IDX(DT_DRV_INST(inst), gpio_pha, idx), label)`` * - ``DT_SPI_DEV_CS_GPIOS_LABEL(spi_dev)`` - ``DT_PROP(DT_SPI_DEV_CS_GPIOS_CTLR(spi_dev), label)`` * - ``DT_INST_SPI_DEV_CS_GPIOS_LABEL(inst)`` - ``DT_PROP(DT_SPI_DEV_CS_GPIOS_CTLR(DT_DRV_INST(inst)), label)`` * - ``DT_LABEL(node_id)`` - ``DT_PROP(node_id, label)`` * - ``DT_BUS_LABEL(node_id)`` - ``DT_PROP(DT_BUS(node_id), label)`` * - ``DT_INST_LABEL(inst)`` - ``DT_INST_PROP(inst, label)`` * - ``DT_INST_BUS_LABEL(inst)`` - ``DT_PROP(DT_BUS(DT_DRV_INST(inst)), label)`` Multi-level Interrupts ====================== * For platforms that enabled :kconfig:option:`CONFIG_MULTI_LEVEL_INTERRUPTS`, the ``IRQ`` variant of the Devicetree macros now return the as-seen value in the devicetree instead of the Zephyr multilevel-encoded IRQ number. To get the IRQ number in Zephyr multilevel-encoded format, use ``IRQN`` variant instead. For example, consider the following devicetree: .. code-block:: devicetree plic: interrupt-controller@c000000 { riscv,max-priority = <7>; riscv,ndev = <1024>; reg = <0x0c000000 0x04000000>; interrupts-extended = <&hlic0 11>; interrupt-controller; compatible = "sifive,plic-1.0.0"; #address-cells = <0x0>; #interrupt-cells = <0x2>; }; uart0: uart@10000000 { interrupts = <10 1>; interrupt-parent = <&plic>; clock-frequency = <0x384000>; reg = <0x10000000 0x100>; compatible = "ns16550"; reg-shift = <0>; }; ``plic`` is a second level interrupt aggregator and ``uart0`` is a child of ``plic``. ``DT_IRQ_BY_IDX(DT_NODELABEL(uart0), 0, irq)`` will return ``10`` (as-seen value in the devicetree), while ``DT_IRQN_BY_IDX(DT_NODELABEL(uart0), 0)`` will return ``(((10 + 1) << CONFIG_1ST_LEVEL_INTERRUPT_BITS) \| 11)``. Drivers and applications that are supposed to work in multilevel-interrupt configurations should be updated to use the ``IRQN`` variant, i.e.: * ``DT_IRQ(node_id, irq)`` -> ``DT_IRQN(node_id)`` * ``DT_IRQ_BY_IDX(node_id, idx, irq)`` -> ``DT_IRQN_BY_IDX(node_id, idx)`` * ``DT_IRQ_BY_NAME(node_id, name, irq)`` -> ``DT_IRQN_BY_NAME(node_id, name)`` * ``DT_INST_IRQ(inst, irq)`` -> ``DT_INST_IRQN(inst)`` * ``DT_INST_IRQ_BY_IDX(inst, idx, irq)`` -> ``DT_INST_IRQN_BY_IDX(inst, idx)`` * ``DT_INST_IRQ_BY_NAME(inst, name, irq)`` -> ``DT_INST_IRQN_BY_NAME(inst, name)`` Analog-to-Digital Converter (ADC) ================================= * The io-channel cells of the following devicetree bindings were reduced from 2 (``positive`` and ``negative``) to the common ``input``, making it possible to use the various ADC DT macros with TI LMP90xxx ADC devices: * :dtcompatible:`ti,lmp90077` * :dtcompatible:`ti,lmp90078` * :dtcompatible:`ti,lmp90079` * :dtcompatible:`ti,lmp90080` * :dtcompatible:`ti,lmp90097` * :dtcompatible:`ti,lmp90098` * :dtcompatible:`ti,lmp90099` * :dtcompatible:`ti,lmp90100` * The io-channel cells of the :dtcompatible:`microchip,mcp3204` and :dtcompatible:`microchip,mcp3208` devicetree bindings were renamed from ``channel`` to the common ``input``, making it possible to use the various ADC DT macros with Microchip MCP320x ADC devices. Bluetooth HCI ============= * The optional :c:func:`setup()` function in the Bluetooth HCI driver API (enabled through :kconfig:option:`CONFIG_BT_HCI_SETUP`) has gained a function parameter of type :c:struct:`bt_hci_setup_params`. By default, the struct is empty, but drivers can opt-in to :kconfig:option:`CONFIG_BT_HCI_SET_PUBLIC_ADDR` if they support setting the controller's public identity address, which will then be passed in the ``public_addr`` field. (:github:`62994`) * The :dtcompatible:`st,hci-spi-v1` should be used instead of :dtcompatible:`zephyr,bt-hci-spi` for the boards which are based on ST BlueNRG-MS. Controller Area Network (CAN) ============================= * The native Linux SocketCAN driver, which can now be used in both :ref:`native_posix<native_posix>` and :ref:`native_sim<native_sim>` with or without an embedded C-library, has been renamed to reflect this: * The devicetree compatible was renamed from ``zephyr,native-posix-linux-can`` to :dtcompatible:`zephyr,native-linux-can`. * The main Kconfig option was renamed from ``CONFIG_CAN_NATIVE_POSIX_LINUX`` to :kconfig:option:`CONFIG_CAN_NATIVE_LINUX`. * Two new structures for holding common CAN controller driver configuration (``struct can_driver_config``) and data (``struct can_driver_data``) fields were introduced. Out-of-tree CAN controller drivers need to be updated to use these new, common configuration and data structures along with their initializer macros. * The optional ``can_get_max_bitrate_t`` CAN controller driver callback was removed in favor of a common accessor function. Out-of-tree CAN controller drivers need to be updated to no longer supply this callback. * The CAN transceiver API function :c:func:`can_transceiver_enable` now takes a :c:type:`can_mode_t` argument for propagating the CAN controller operational mode to the CAN transceiver. Out-of-tree CAN controller and CAN transceiver drivers need to be updated to match this new API function signature. * The ``CAN_FILTER_FDF`` flag for filtering classic CAN/CAN FD frames was removed since no known CAN controllers implement support for this. Applications can still filter on classic CAN/CAN FD frames in their receive callback functions as needed. * The ``CAN_FILTER_DATA`` and ``CAN_FILTER_RTR`` flags for filtering between Data and Remote Transmission Request (RTR) frames were removed since not all CAN controllers implement support for individual RX filtering based on the RTR bit. Applications can now use :kconfig:option:`CONFIG_CAN_ACCEPT_RTR` to either accept incoming RTR frames matching CAN filters or reject all incoming CAN RTR frames (the default). When :kconfig:option:`CONFIG_CAN_ACCEPT_RTR` is enabled, applications can still filter between Data and RTR frames in their receive callback functions as needed. * The :dtcompatible:`st,stm32h7-fdcan` CAN controller driver now supports configuring the domain/kernel clock via devicetree. Previously, the driver only supported using the PLL1_Q clock for kernel clock, but now it defaults to the HSE clock, which is the chip default. Boards that use the PLL1_Q clock for FDCAN will need to override the ``clocks`` property as follows: .. code-block:: devicetree &fdcan1 { clocks = <&rcc STM32_CLOCK_BUS_APB1_2 0x00000100>, <&rcc STM32_SRC_PLL1_Q FDCAN_SEL(1)>; }; Display ======= * ILI9XXX based displays now use the MIPI DBI driver class. These displays must now be declared within a MIPI DBI driver wrapper device, which will manage interfacing with the display. Note that the `cmd-data-gpios` pin has changed polarity with this update, to align better with the new `dc-gpios` name. For an example, see below: .. code-block:: devicetree /* Legacy ILI9XXX display definition / &spi2 { ili9340: ili9340@0 { compatible = "ilitek,ili9340"; reg = <0>; spi-max-frequency = <32000000>; reset-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>; cmd-data-gpios = <&gpio0 12 GPIO_ACTIVE_LOW>; rotation = <270>; width = <320>; height = <240>; }; }; / New display definition with MIPI DBI device / mipi_dbi { compatible = "zephyr,mipi-dbi-spi"; reset-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>; dc-gpios = <&gpio0 12 GPIO_ACTIVE_HIGH>; spi-dev = <&spi2>; #address-cells = <1>; #size-cells = <0>; ili9340: ili9340@0 { compatible = "ilitek,ili9340"; reg = <0>; mipi-max-frequency = <32000000>; rotation = <270>; width = <320>; height = <240>; }; }; Flash ===== The :dtcompatible:`st,stm32-ospi-nor` and :dtcompatible:`st,stm32-qspi-nor` give the nor flash base address and size (in Bytes) with the reg property as follows. The <size> property is not used anymore. .. code-block:: devicetree mx25lm51245: ospi-nor-flash@70000000 { compatible = "st,stm32-ospi-nor"; reg = <0x70000000 DT_SIZE_M(64)>; /* 512 Mbits/ }; General Purpose I/O (GPIO) ========================== The :dtcompatible:`nxp,pcf8574` driver has been renamed to :dtcompatible:`nxp,pcf857x`. (:github:`67054`) to support pcf8574 and pcf8575. The Kconfig option has been renamed from :kconfig:option:`CONFIG_GPIO_PCF8574` to :kconfig:option:`CONFIG_GPIO_PCF857X`. The Device Tree can be configured as follows: .. code-block:: devicetree &i2c { status = "okay"; pcf8574: pcf857x@20 { compatible = "nxp,pcf857x"; status = "okay"; reg = <0x20>; gpio-controller; #gpio-cells = <2>; ngpios = <8>; }; pcf8575: pcf857x@21 { compatible = "nxp,pcf857x"; status = "okay"; reg = <0x21>; gpio-controller; #gpio-cells = <2>; ngpios = <16>; }; }; Input ===== * Touchscreen drivers :dtcompatible:`focaltech,ft5336` and :dtcompatible:`goodix,gt911` were using the incorrect polarity for the respective ``reset-gpios``. This has been fixed so those signals now have to be flagged as :c:macro:`GPIO_ACTIVE_LOW` in the devicetree. (:github:`64800`) Interrupt Controller ==================== * The function signature of the ``isr_t`` callback function passed to the ``shared_irq`` interrupt controller driver API via :c:func:`shared_irq_isr_register()` has changed. The callback now takes an additional `irq_number` parameter. Out-of-tree users of this API will need to be updated. (:github:`66427`) Renesas RA Series Drivers ========================= * Several Renesas RA series drivers Kconfig options have been renamed: * ``CONFIG_CLOCK_CONTROL_RA`` -> :kconfig:option:`CONFIG_CLOCK_CONTROL_RENESAS_RA` * ``CONFIG_GPIO_RA`` -> :kconfig:option:`CONFIG_GPIO_RENESAS_RA` * ``CONFIG_PINCTRL_RA`` -> :kconfig:option:`CONFIG_PINCTRL_RENESAS_RA` * ``CONFIG_UART_RA`` -> :kconfig:option:`CONFIG_UART_RENESAS_RA` Sensors ======= * The :dtcompatible:`st,lsm6dsv16x` sensor driver has been changed to support configuration of both int1 and int2 pins. The DT attribute ``irq-gpios`` has been removed and substituted by two new attributes, ``int1-gpios`` and ``int2-gpios``. These attributes must be configured in the Device Tree similarly to the following example: .. code-block:: devicetree / { lsm6dsv16x@0 { compatible = "st,lsm6dsv16x"; int1-gpios = <&gpioa 4 GPIO_ACTIVE_HIGH>; int2-gpios = <&gpiod 11 GPIO_ACTIVE_HIGH>; drdy-pin = <2>; }; }; Serial ====== * Runtime configuration is now disabled by default for Nordic UART drivers. The motivation for the change is that this feature is rarely used and disabling it significantly reduces the memory footprint. Timer ===== * The :dtcompatible:`st,stm32-lptim` lptim which is selected for counting ticks during low power modes is identified by stm32_lp_tick_source in the device tree as follows. The stm32_lptim_timer driver has been changed to support this. .. code-block:: devicetree stm32_lp_tick_source: &lptim1 { status = "okay"; }; Bluetooth ********* * ATT now has its own TX buffer pool. If extra ATT buffers were configured using :kconfig:option:`CONFIG_BT_L2CAP_TX_BUF_COUNT`, they now instead should be configured through :kconfig:option:`CONFIG_BT_ATT_TX_COUNT`. * The HCI implementation for both the Host and the Controller sides has been renamed for the IPC transport. The ``CONFIG_BT_RPMSG`` Kconfig option is now :kconfig:option:`CONFIG_BT_HCI_IPC`, and the ``zephyr,bt-hci-rpmsg-ipc`` Devicetree chosen is now ``zephyr,bt-hci-ipc``. The existing sample has also been renamed, from ``samples/bluetooth/hci_rpmsg`` to ``samples/bluetooth/hci_ipc``. (:github:`64391`) * The BT GATT callback list, appended to by :c:func:`bt_gatt_cb_register`, is no longer cleared on :c:func:`bt_enable`. Callbacks can now be registered before the initial call to :c:func:`bt_enable`, and should no longer be re-registered after a :c:func:`bt_disable` :c:func:`bt_enable` cycle. (:github:`63693`) * The Bluetooth UUID has been modified to rodata in ``BT_UUID_DECLARE_16``, ``BT_UUID_DECLARE_32`` and ``BT_UUID_DECLARE_128`` as the return value has been changed to ``const``. Any pointer to a UUID must be prefixed with ``const``, otherwise there will be a compilation warning. For example change ``struct bt_uuid uuid = BT_UUID_DECLARE_16(xx)`` to ``const struct bt_uuid uuid = BT_UUID_DECLARE_16(xx)``. (:github:`66136`) * The :c:func:`bt_l2cap_chan_send` API no longer allocates buffers from the same pool as its `buf` parameter when segmenting SDUs into PDUs. In order to reproduce the previous behavior, the application should register the `alloc_seg` channel callback and allocate from the same pool as `buf`. * The :c:func:`bt_l2cap_chan_send` API now requires the application to reserve enough bytes for the L2CAP headers. Call ``net_buf_reserve(buf, BT_L2CAP_SDU_CHAN_SEND_RESERVE);`` at buffer allocation time to do so. * `BT_ISO_TIMESTAMP_NONE` has been removed and the `ts` parameter of :c:func:`bt_iso_chan_send` has as well. :c:func:`bt_iso_chan_send` now always sends without timestamp. To send with a timestamp, :c:func:`bt_iso_chan_send_ts` can be used. * The ``CONFIG_BT_HCI_RESERVE`` and ``CONFIG_BT_HCI_RAW_RESERVE`` Kconfig options were removed. All buffers get by default one byte of headroom now, which HCI transport implementations can rely on (whether they need it or not). Bluetooth Mesh ============== * The Bluetooth Mesh ``model`` declaration has been changed to add prefix ``const``. The ``model->user_data``, ``model->elem_idx`` and ``model->mod_idx`` field has been changed to the new runtime structure, replaced by ``model->rt->user_data``, ``model->rt->elem_idx`` and ``model->rt->mod_idx`` separately. (:github:`65152`) * The Bluetooth Mesh ``element`` declaration has been changed to add prefix ``const``. The ``elem->addr`` field has been changed to the new runtime structure, replaced by ``elem->rt->addr``. (:github:`65388`) * Deprecated :kconfig:option:`CONFIG_BT_MESH_PROV_DEVICE`. This option is replaced by new option :kconfig:option:`CONFIG_BT_MESH_PROVISIONEE` to be aligned with Mesh Protocol Specification v1.1, section 5.4. (:github:`64252`) * Removed the ``CONFIG_BT_MESH_V1d1`` Kconfig option. * Removed the ``CONFIG_BT_MESH_TX_SEG_RETRANS_COUNT``, ``CONFIG_BT_MESH_TX_SEG_RETRANS_TIMEOUT_UNICAST``, ``CONFIG_BT_MESH_TX_SEG_RETRANS_TIMEOUT_GROUP``, ``CONFIG_BT_MESH_SEG_ACK_BASE_TIMEOUT``, ``CONFIG_BT_MESH_SEG_ACK_PER_HOP_TIMEOUT``, ``BT_MESH_SEG_ACK_PER_SEGMENT_TIMEOUT`` Kconfig options. They are superseded by the :kconfig:option:`CONFIG_BT_MESH_SAR_TX_SEG_INT_STEP`, :kconfig:option:`CONFIG_BT_MESH_SAR_TX_UNICAST_RETRANS_COUNT`, :kconfig:option:`CONFIG_BT_MESH_SAR_TX_UNICAST_RETRANS_WITHOUT_PROG_COUNT`, :kconfig:option:`CONFIG_BT_MESH_SAR_TX_UNICAST_RETRANS_INT_STEP`, :kconfig:option:`CONFIG_BT_MESH_SAR_TX_UNICAST_RETRANS_INT_INC`, :kconfig:option:`CONFIG_BT_MESH_SAR_TX_MULTICAST_RETRANS_COUNT`, :kconfig:option:`CONFIG_BT_MESH_SAR_TX_MULTICAST_RETRANS_INT`, :kconfig:option:`CONFIG_BT_MESH_SAR_RX_SEG_THRESHOLD`, :kconfig:option:`CONFIG_BT_MESH_SAR_RX_ACK_DELAY_INC`, :kconfig:option:`CONFIG_BT_MESH_SAR_RX_SEG_INT_STEP`, :kconfig:option:`CONFIG_BT_MESH_SAR_RX_DISCARD_TIMEOUT`, :kconfig:option:`CONFIG_BT_MESH_SAR_RX_ACK_RETRANS_COUNT` Kconfig options. Bluetooth Audio =============== * The ``BT_AUDIO_CODEC_LC3_`` values from ``<zephyr/bluetooth/audio/lc3.h>`` have moved to ``<zephyr/bluetooth/audio/audio.h>`` and have the ``LC3`` part of their names replaced by a more semantically correct name: e.g. ``BT_AUDIO_CODEC_LC3_CHAN_COUNT`` is now ``BT_AUDIO_CODEC_CAP_TYPE_CHAN_COUNT``, ``BT_AUDIO_CODEC_LC3_FREQ`` is now ``BT_AUDIO_CODEC_CAP_TYPE_FREQ``, and ``BT_AUDIO_CODEC_CONFIG_LC3_FREQ`` is now ``BT_AUDIO_CODEC_CFG_FREQ``, etc. Similarly the enumerations have also been renamed. E.g. ``bt_audio_codec_config_freq`` is now ``bt_audio_codec_cfg_freq``, ``bt_audio_codec_capability_type`` is now ``bt_audio_codec_cap_type``, ``bt_audio_codec_config_type`` is now ``bt_audio_codec_cfg_type``, etc. (:github:`67024`) The `ts` parameter of :c:func:`bt_bap_stream_send` has been removed. :c:func:`bt_bap_stream_send` now always sends without timestamp. To send with a timestamp, :c:func:`bt_bap_stream_send_ts` can be used. * The `ts` parameter of :c:func:`bt_cap_stream_send` has been removed. :c:func:`bt_cap_stream_send` now always sends without timestamp. To send with a timestamp, :c:func:`bt_cap_stream_send_ts` can be used. Networking ********** * The CoAP public API has some minor changes to take into account. The :c:func:`coap_remove_observer` now returns a result if the observer was removed. This change is used by the newly introduced :ref:`coap_server_interface` subsystem. Also, the ``request`` argument for :c:func:`coap_well_known_core_get` is made ``const``. (:github:`64265`) * CoAP observer events have moved from a callback function in a CoAP resource to the Network Events subsystem. The ``CONFIG_COAP_OBSERVER_EVENTS`` configuration option has been removed. (:github:`65936`) * The CoAP public API function :c:func:`coap_pending_init` has changed. The parameter ``retries`` is replaced with a pointer to :c:struct:`coap_transmission_parameters`. This allows to specify retransmission parameters of the confirmable message. It is safe to pass a NULL pointer to use default values. (:github:`66482`) * The CoAP public API functions :c:func:`coap_service_send` and :c:func:`coap_resource_send` have changed. An additional parameter pointer to :c:struct:`coap_transmission_parameters` has been added. It is safe to pass a NULL pointer to use default values. (:github:`66540`) * The IGMP multicast library now supports IGMPv3. This results in a minor change to the existing api. The :c:func:`net_ipv4_igmp_join` now takes an additional argument of the type ``const struct igmp_param param``. This allows IGMPv3 to exclude/include certain groups of addresses. If this functionality is not used or available (when using IGMPv2), you can safely pass a NULL pointer. IGMPv3 can be enabled using the Kconfig ``CONFIG_NET_IPV4_IGMPV3``. (:github:`65293`) The network stack now uses a separate IPv4 TTL (time-to-live) value for multicast packets. Before, the same TTL value was used for unicast and multicast packets. The IPv6 hop limit value is also changed so that unicast and multicast packets can have a different one. (:github:`65886`) * The Ethernet phy APIs defined in ``<zephyr/net/phy.h>`` are removed from syscall list. The APIs were marked as callable from usermode but in practice this does not work as the device cannot be accessed from usermode thread. This means that the API calls will need to made from supervisor mode thread. * The zperf ratio between mbps and kbps, kbps and bps is changed to 1000, instead of 1024, to align with iperf ratios. * For network buffer pools maximum allocation size was added to a common structure ``struct net_buf_data_alloc`` as a new field ``max_alloc_size``. Similar member ``data_size`` of ``struct net_buf_pool_fixed`` that was specific only for buffer pools with a fixed size was removed. Other Subsystems **************** LoRaWAN ======= * The API to register a callback to provide battery level information to the LoRaWAN stack has been renamed from ``lorawan_set_battery_level_callback`` to :c:func:`lorawan_register_battery_level_callback` and the return type is now ``void``. This is more consistent with similar functions for downlink and data rate changed callbacks. (:github:`65103`) MCUmgr ====== * MCUmgr applications that make use of serial transports (shell or UART) must now select :kconfig:option:`CONFIG_CRC`, this was previously erroneously selected if MCUmgr was enabled, when for non-serial transports it was not needed. (:github:`64078`) Shell ===== * The following subsystem and driver shell modules are now disabled by default. Each required shell module must now be explicitly enabled via Kconfig (:github:`65307`): * :kconfig:option:`CONFIG_ACPI_SHELL` * :kconfig:option:`CONFIG_ADC_SHELL` * :kconfig:option:`CONFIG_AUDIO_CODEC_SHELL` * :kconfig:option:`CONFIG_CAN_SHELL` * :kconfig:option:`CONFIG_CLOCK_CONTROL_NRF_SHELL` * :kconfig:option:`CONFIG_DAC_SHELL` * :kconfig:option:`CONFIG_DEBUG_COREDUMP_SHELL` * :kconfig:option:`CONFIG_EDAC_SHELL` * :kconfig:option:`CONFIG_EEPROM_SHELL` * :kconfig:option:`CONFIG_FLASH_SHELL` * :kconfig:option:`CONFIG_HWINFO_SHELL` * :kconfig:option:`CONFIG_I2C_SHELL` * :kconfig:option:`CONFIG_LOG_CMDS` * :kconfig:option:`CONFIG_LORA_SHELL` * :kconfig:option:`CONFIG_MCUBOOT_SHELL` * :kconfig:option:`CONFIG_MDIO_SHELL` * :kconfig:option:`CONFIG_OPENTHREAD_SHELL` * :kconfig:option:`CONFIG_PCIE_SHELL` * :kconfig:option:`CONFIG_PSCI_SHELL` * :kconfig:option:`CONFIG_PWM_SHELL` * :kconfig:option:`CONFIG_REGULATOR_SHELL` * :kconfig:option:`CONFIG_SENSOR_SHELL` * :kconfig:option:`CONFIG_SMBUS_SHELL` * :kconfig:option:`CONFIG_STATS_SHELL` * :kconfig:option:`CONFIG_USBD_SHELL` * :kconfig:option:`CONFIG_USBH_SHELL` * :kconfig:option:`CONFIG_W1_SHELL` * :kconfig:option:`CONFIG_WDT_SHELL` * The ``SHELL_UART_DEFINE`` macro now only requires a ``_name`` argument. In the meantime, the macro accepts additional arguments (ring buffer TX & RX size arguments) for compatibility with previous Zephyr version, but they are ignored, and will be removed in future release. * :kconfig:option:`CONFIG_SHELL_BACKEND_SERIAL_API` now does not automatically default to :kconfig:option:`CONFIG_SHELL_BACKEND_SERIAL_API_ASYNC` when :kconfig:option:`CONFIG_UART_ASYNC_API` is enabled, :kconfig:option:`CONFIG_SHELL_ASYNC_API` also has to be enabled in order to use the asynchronous serial shell (:github:`68475`). ZBus ==== * The ``CONFIG_ZBUS_MSG_SUBSCRIBER_NET_BUF_DYNAMIC`` and ``CONFIG_ZBUS_MSG_SUBSCRIBER_NET_BUF_STATIC`` zbus options are renamed. Instead, the new :kconfig:option:`CONFIG_ZBUS_MSG_SUBSCRIBER_BUF_ALLOC_DYNAMIC` and :kconfig:option:`CONFIG_ZBUS_MSG_SUBSCRIBER_BUF_ALLOC_STATIC` options should be used. (:github:`65632`) * To enable the zbus HLP priority boost, the developer must call the :c:func:`zbus_obs_attach_to_thread` inside the attaching thread. The observer will then assume the attached thread priority which will be used by zbus to calculate HLP priority. (:github:`63183`) Userspace ********* * A number of userspace related functions have been moved out of the ``z_`` namespace and into the kernel namespace. * ``Z_OOPS`` to :c:macro:`K_OOPS` * ``Z_SYSCALL_MEMORY`` to :c:macro:`K_SYSCALL_MEMORY` * ``Z_SYSCALL_MEMORY_READ`` to :c:macro:`K_SYSCALL_MEMORY_READ` * ``Z_SYSCALL_MEMORY_WRITE`` to :c:macro:`K_SYSCALL_MEMORY_WRITE` * ``Z_SYSCALL_DRIVER_OP`` to :c:macro:`K_SYSCALL_DRIVER_OP` * ``Z_SYSCALL_SPECIFIC_DRIVER`` to :c:macro:`K_SYSCALL_SPECIFIC_DRIVER` * ``Z_SYSCALL_OBJ`` to :c:macro:`K_SYSCALL_OBJ` * ``Z_SYSCALL_OBJ_INIT`` to :c:macro:`K_SYSCALL_OBJ_INIT` * ``Z_SYSCALL_OBJ_NEVER_INIT`` to :c:macro:`K_SYSCALL_OBJ_NEVER_INIT` * ``z_user_from_copy`` to :c:func:`k_usermode_from_copy` * ``z_user_to_copy`` to :c:func:`k_usermode_to_copy` * ``z_user_string_copy`` to :c:func:`k_usermode_string_copy` * ``z_user_string_alloc_copy`` to :c:func:`k_usermode_string_alloc_copy` * ``z_user_alloc_from_copy`` to :c:func:`k_usermode_alloc_from_copy` * ``z_user_string_nlen`` to :c:func:`k_usermode_string_nlen` * ``z_dump_object_error`` to :c:func:`k_object_dump_error` * ``z_object_validate`` to :c:func:`k_object_validate` * ``z_object_find`` to :c:func:`k_object_find` * ``z_object_wordlist_foreach`` to :c:func:`k_object_wordlist_foreach` * ``z_thread_perms_inherit`` to :c:func:`k_thread_perms_inherit` * ``z_thread_perms_set`` to :c:func:`k_thread_perms_set` * ``z_thread_perms_clear`` to :c:func:`k_thread_perms_clear` * ``z_thread_perms_all_clear`` to :c:func:`k_thread_perms_all_clear` * ``z_object_uninit`` to :c:func:`k_object_uninit` * ``z_object_recycle`` to :c:func:`k_object_recycle` * ``z_obj_validation_check`` to :c:func:`k_object_validation_check` * ``Z_SYSCALL_VERIFY_MSG`` to :c:macro:`K_SYSCALL_VERIFY_MSG` * ``z_object`` to :c:struct:`k_object` * ``z_object_init`` to :c:func:`k_object_init` * ``z_dynamic_object_aligned_create`` to :c:func:`k_object_create_dynamic_aligned` Architectures ************* Xtensa ====== * :kconfig:option:`CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC` no longer has a default in the architecture layer. Instead, SoCs or boards will need to define it. * Scratch registers ``ZSR_ALLOCA`` has been renamed to ``ZSR_A0SAVE``. * Renamed files with hyhphens to underscores: * ``xtensa-asm2-context.h`` to ``xtensa_asm2_context.h`` * ``xtensa-asm2-s.h`` to ``xtensa_asm2_s.h`` * ``xtensa_asm2.h`` has been removed. Use ``xtensa_asm2_context.h`` instead for stack frame structs. * Renamed functions out of ``z_`` namespace into ``xtensa_`` namespace. * ``z_xtensa_irq_enable`` to :c:func:`xtensa_irq_enable` * ``z_xtensa_irq_disable`` to :c:func:`xtensa_irq_disable` * ``z_xtensa_irq_is_enabled`` to :c:func:`xtensa_irq_is_enabled` ```	/content/code_sandbox/doc/releases/migration-guide-3.6.rst	restructuredtext	2016-05-26T17:54:19	2024-08-16T18:09:06	zephyr	zephyrproject-rtos/zephyr	10,307	8,760

Security Vulnerability Related ****************************** The following security vulnerabilities (CVEs) were addressed in this release: * Fix CVE-2020-10019 * Fix CVE-2020-10021 * Fix CVE-2020-10023 * Fix CVE-2020-10024 * Fix CVE-2020-10026 * Fix CVE-2020-10027 * Fix CVE-2020-10028 * Fix CVE-2020-10058 More detailed information can be found in: path_to_url API Changes *********** Deprecated in this release ========================== * Settings * SETTINGS_USE_BASE64, encoding values in base64 is marked for removal. Stable API changes in this release ================================== * GPIO * GPIO API has been reworked to support flags known from Linux DTS GPIO bindings. They will typically be defined in the board DTS file - GPIO_ACTIVE_LOW, GPIO_ACTIVE_HIGH used to set pin active level - GPIO_OPEN_DRAIN, GPIO_OPEN_SOURCE used to configure pin as open drain or open source - GPIO_PULL_UP, GPIO_PULL_DOWN used to configure pin bias * Reading / writing of pin logical level is supported by gpio_pin_get, gpio_pin_set functions. * Reading / writing of pin physical level is supported by gpio_pin_get_raw, gpio_pin_set_raw functions. * New set of port functions that operate simultaneously on multiple pins that belong to the same controller. * Interrupts should be configured by a dedicated gpio_pin_interrupt_configure() function. Configuring interrupts via gpio_pin_configure() is still supported but this feature will be removed in future releases. * New set of flags allows to set arbitrary interrupt configuration (if supported by the driver) based on pin physical or logical levels. * New set of flags to configure pin as input, output or in/out as well as set output initial state. * Majority of the old GPIO API has been deprecated. While the care was taken to preserve backward compatibility due to the scope of the work it was not possible to fully achieve this goal. We recommend to switch to the new GPIO API as soon as possible. * Areas where the deprecated API may behave differently to the original old implementation are: - Configuration of pin interrupts, especially involving GPIO_INT_ACTIVE_LOW and GPIO_POL_INV flags. - Behavior of gpio_pin_configure() when invoked without interrupt related flags. In the new implementation of this deprecated functionality the interrupts remain unmodified. In the original implementation some of the GPIO drivers would disable the interrupts. * Several drivers that rely on the functionality provided by the GPIO API were reworked to honor pin active level. Any external users of these drivers will have to update their DTS board files. - bluetooth/hci/spi.c - display/display_ili9340.c - display/ssd1306.c - ieee802154/ieee802154_mcr20a.c - ieee802154/ieee802154_rf2xx.c - lora/sx1276.c - wifi/eswifi/eswifi_core.c - majority of the sensor drivers * PWM * The pwm_pin_set_cycles(), pwm_pin_set_usec(), and pwm_pin_set_nsec() functions now take a flags parameter. The newly introduced flags are PWM_POLARITY_NORMAL and PWM_POLARITY_INVERTED for specifying the polarity of the PWM signal. The flags parameter can be set to 0 if no flags are required (the default is PWM_POLARITY_NORMAL). * Similarly, the pwm_pin_set_t PWM driver API function function now takes a flags parameter. The PWM controller driver must check the value of the flags parameter and return -ENOTSUP if any unsupported flag is set. * USB * The usb_enable() function, which was previously invoked automatically by the USB stack, now needs to be explicitly called by the application in order to enable the USB subsystem. * The usb_enable() function now takes a parameter, usb_dc_status_callback which can be set by the application to a callback to receive status events from the USB stack. The parameter can also be set to NULL if no callback is required. * nRF flash driver * The nRF Flash driver has changed its default write block size to 32-bit aligned. Previous emulation of 8-bit write block size can be selected using the CONFIG_SOC_FLASH_NRF_EMULATE_ONE_BYTE_WRITE_ACCESS Kconfig option. Usage of 8-bit write block size emulation is only recommended for compatibility with older storage contents. * Clock control * The callback prototype (clock_control_cb_t) has now additional argument (clock_control_subsys_t) indicating which clock subsystem got started. Removed APIs in this release ============================ * Shell * SHELL_CREATE_STATIC_SUBCMD_SET (deprecated), replaced by SHELL_STATIC_SUBCMD_SET_CREATE * SHELL_CREATE_DYNAMIC_CMD (deprecated), replaced by SHELL_DYNAMIC_CMD_CREATE * Newtron Flash File System (NFFS) was removed. NFFS was removed since it has serious issues, not fixed since a long time. Where it was possible NFFS usage was replaced by LittleFS usage as the better substitute. Kernel ****** * Addressed some race conditions observed on SMP-enabled systems * Propagate a distinct error code if a workqueue item is submitted that has already been completed * Disable preemption when handing fatal errors * Fix an issue with the system call stack frame if the system call is preempted and then later tries to Z_OOPS() * add k_thread_stack_space_get() system call for analyzing thread stack space.

Security Vulnerability Related ****************************** The following security vulnerability (CVE) was addressed in this release: * Fixes CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing. Bluetooth ********* * Qualification: * 1.14.x Host subsystem qualified with QDID 139258 * 1.14.x Mesh subsystem qualified with QDID 139259 * 1.14.x Controller component qualified on Nordic nRF52 with QDID 135679 Issues Fixed ************ These GitHub issues were addressed since the previous 1.14.0 tagged release: .. comment List derived from GitHub Issue query: ... * :github:`issuenumber` -

Major enhancements with this release include: * The Zephyr project now supports over 160 different board configurations spanning 8 architectures. All architectures are rigorously tested and validated using one of the many simulation platforms supported by the project: QEMU, Renode, ARC Simulator, and the native POSIX configuration. * The timing subsystem has been reworked and reimplemented, greatly simplifying the resulting drivers, removing thousands of lines of code, and reducing a typical kernel build size by hundreds of bytes. TICKLESS_KERNEL mode is now the default on all architectures. * The Symmetric Multi-Processing (SMP) subsystem continues to evolve with the addition of a new CPU affinity API that can "pin" threads to specific cores or sets of cores. The core kernel no longer uses the global irq_lock on SMP systems, and exclusively uses the spinlock API (which on uniprocessor systems reduces to the same code). * Zephyr now has support for the x86_64 architecture. It is currently implemented only for QEMU targets, supports arbitrary numbers of CPUs, and runs in SMP mode by default, our first platform to do so. * We've overhauled the Network packet (:ref:`net-pkt <net_pkt_interface>`) API and moved the majority of components and protocols to use the :ref:`BSD socket API <bsd_sockets_interface>`, including MQTT, CoAP, LWM2M, and SNTP. * We enhanced the native POSIX port by adding UART, USB, and display drivers. Based on this port, we added a simulated NRF52832 SoC which enables running full system, multi-node simulations, without the need of real hardware. * We added an experimental BLE split software Controller with Upper Link Layer and Lower Link Layer for supporting multiple BLE radio hardware architectures. * The power management subsystem has been overhauled to support device idle power management and move most of the power management logic from the application back to the BSP. * We introduced major updates and an overhaul to both the logging and shell subsystems, supporting multiple back-ends, integration of logging into the shell, and delayed log processing. * Introduced the ``west`` tool for management of multiple repositories and enhanced support for flashing and debugging. * Added support for application user mode, application memory partitions, and hardware stack protection in ARMv8m * Applied MISRA-C code guideline on the kernel and core components of Zephyr. MISRA-C is a well established code guideline focused on embedded systems and aims to improve code safety, security and portability. The following sections provide detailed lists of changes by component. Security Vulnerability Related ****************************** The following security vulnerabilities (CVEs) were addressed in this release: * Tinycrypt HMAC-PRNG implementation doesn't take the HMAC state clearing into account as it performs the HMAC operations, thereby using a incorrect HMAC key for some of the HMAC operations. (CVE-2017-14200) * The shell DNS command can cause unpredictable results due to misuse of stack variables. (CVE-2017-14201) * The shell implementation does not protect against buffer overruns resulting in unpredictable behavior. (CVE-2017-14202) * We introduced Kernel Page Table Isolation, a technique for mitigating the Meltdown security vulnerability on x86 systems. This technique helps isolate user and kernel space memory by ensuring non-essential kernel pages are unmapped in the page tables when the CPU is running in the least privileged user mode, Ring 3. This is the fix for Rogue Data Cache Load. (CVE-2017-5754) * We also addressed these CVEs for the x86 port: - Bounds Check Bypass (CVE-2017-5753) - Branch Target Injection (CVE-2017-5715) - Speculative Store Bypass (CVE-2018-3639) - L1 Terminal Fault (CVE-2018-3620) - Lazy FP State Restore (CVE-2018-3665) Kernel ****** * The timing subsystem has been reworked and mostly replaced: - The timer driver API has been extensively reworked, greatly simplifying the resulting drivers. By removing thousands of lines of code, we reduced the size of a typical kernel build by hundreds of bytes. - TICKLESS_KERNEL mode is now the default on all architectures. Many bugs were fixed in this support. * Lots of work on the rapidly-evolving SMP subsystem: - There is a new CPU affinity API available to "pin" threads to specific cores or sets of cores. - The core kernel is now 100% free of use of the global irq_lock on SMP systems, and exclusively uses the spinlock API (which on uniprocessor systems reduces to the same code). - Zephyr now has a simple interprocessor interrupt framework for applications, such as the scheduler, to use for synchronously notifying other processors of state changes. It's currently implemented only on x86_64 and used only for thread abort. * Zephyr now has support for the x86_64 architecture. It is currently implemented only for QEMU targets. - It supports arbitrary numbers of CPUs in SMP, and runs in SMP mode by default, our first platform to do so. - It currently runs code built for the "x32" ABI, which is a native 64-bit hardware state, where pointers are 32 bit in memory. Zephyr still has some lurking word size bugs that will need to be fixed to turn on native 64 bit code generation. * K_THREAD_STACK_BUFFER() has been demoted to a private API and will be removed in a future Zephyr release. * A new API sys_mutex has been introduced. It has the same semantics as a k_mutex, but the memory for it can reside in user memory and so no explicit permission management is required. * sys_mem_pool() now uses a sys_mutex() for concurrency control. * Memory protection changes: - CONFIG_APPLICATION_MEMORY option has been removed from Zephyr. All test cases have been appropriately converted to use memory domains. - The build time memory domain partition generation mechanism, formerly an optional feature under CONFIG_APP_SHARED_MEM, has been overhauled and is now a core part of memory protection. - Userspace is no longer enabled by default for tests. Tests that are written to execute wholly or in part in user mode will need to enable CONFIG_TEST_USERSPACE in the test's project configuration. There are assertions in place to enforce that this is done. - The default stack size for handling system calls has been increased to 1024 bytes. * We started applying MISRA-C (path_to_url code guideline on the Zephyr kernel. MISRA-C is a well established code guideline focused on embedded systems and aims to improve code safety, security, and portability. This initial effort was narrowed to the Zephyr kernel and architecture code, and focused only on mandatory and required rules. The following rules were addressed: - Namespace changes - Normalize switch() operators - Avoid implicit conversion to boolean types - Fix and normalize headers guard - Make if() evaluate boolean operands - Remove all VLAs (variable length array) - Avoid undefined and implementation defined behavior with shift operator - Remove recursions Architectures ************* * Introduced X86_64 (64 bit) architecture support with SMP features * High-level Kconfig symbol structure for Trusted Execution * ARM: * Re-architect Memory Protection code for ARM and NXP * Fully support application user mode, memory partitions, and stack protection in ARMv8m * Support built-in stack overflow protection in user mode in ARMv8m * Fix stack overflow error reporting * Support executing from SRAM in XIP builds * Support non-cacheable memory sections * Remove power-of-two align and size requirement for ARMv8-m * Introduce sync barriers in ARM-specific IRQ lock/unlock functions * Enforce double-word stack alignment on exception entry * API to allow Non-Secure FPU Access (ARMv8-M) * Various enhancements in ARM system boot code * Indicate Secure domain fault in Non-Secure fault exception * Update ARM CMSIS headers to version 5.4.0 * ARC: * Userspace and MPU driver improvements * Optimization of the thread stack definition macros * Bug fixes: handling of lp_xxx registers in _rirq_return_from_coop, nested interrupt handling, hardware stack bounds checking, execution benchmarking * Atomic operations are now usable from user mode on all ARC CPUs * x86: - Support for non-PAE page tables has been dropped. - Fixed various security CVEs related to micro-architecture side-effects of speculative execution, as detailed in the security notes. - Added robustness when reporting exceptions generated due to stack overflows or induced in user mode - Pages containing read-only data no longer have the execute disable (XD) bit un-set. - Fix potential IRQ stack corruption when handling double faults Boards & SoC Support ******************** * Added the all new :ref:`NRF52 simulated board <nrf52_bsim>`: This simulator models some of the hardware in an NRF52832 SOC, to enable running full system, multi-node simulations, without the need of real hardware. It enables fast, reproducible testing, development, and debugging of an application, BlueTooth (BT) stack, and kernel.

```restructuredtext :orphan: .. _zephyr_3.2: Zephyr 3.2.0 ############ We are pleased to announce the release of Zephyr version 3.2.0. Major enhancements with this release include: * Introduced :ref:`sysbuild`. * Added support for :ref:`bin-blobs` (also see :ref:`west-blobs`). * Added support for Picolibc (see :kconfig:option:`CONFIG_PICOLIBC`). * Converted all supported boards from ``pinmux`` to :ref:`pinctrl-guide`. * Initial support for :ref:`i3c_api` controllers. * Support for :ref:`W1 api<w1_api>`. * Improved access to Devicetree compatibles from Kconfig (new generated ``DTS_HAS_..._ENABLED`` configs). The following sections provide detailed lists of changes by component. Security Vulnerability Related ****************************** The following CVEs are addressed by this release: More detailed information can be found in: path_to_url * CVE-2022-2993: Under embargo until 2022-11-03 * CVE-2022-2741: Under embargo until 2022-10-14 API Changes *********** Changes in this release ======================= * Zephyr now requires Python 3.8 or higher * Changed :c:struct:`spi_cs_control` to remove anonymous struct. This causes possible breakage for static initialization of the struct. Updated :c:macro:`SPI_CS_CONTROL_PTR_DT` to reflect this change. * The :kconfig:option:`CONFIG_LEGACY_INCLUDE_PATH` option has been disabled by default, all upstream code and modules have been converted to use ``<zephyr/...>`` header paths. The option is still available to facilitate the migration of external applications, but will be removed with the 3.4 release. The :zephyr_file:`scripts/utils/migrate_includes.py` script is provided to automate the migration. * :zephyr_file:`include/zephyr/zephyr.h` no longer defines ``__ZEPHYR__``. This definition can be used by third-party code to compile code conditional to Zephyr. The definition is already injected by the Zephyr build system. Therefore, any third-party code integrated using the Zephyr build system will require no changes. External build systems will need to inject the definition by themselves, if they did not already. * :zephyr_file:`include/zephyr/zephyr.h` has been deprecated in favor of :zephyr_file:`include/zephyr/kernel.h`, since it only included that header. No changes are required by applications other than replacing ``#include <zephyr/zephyr.h>`` with ``#include <zephyr/kernel.h>``. * Bluetooth: Applications where :kconfig:option:`CONFIG_BT_EATT` is enabled must set the :c:member:`chan_opt` field on the GATT parameter structs. To keep the old behavior use :c:enumerator:`BT_ATT_CHAN_OPT_NONE`. * CAN * The Zephyr SocketCAN definitions have been moved from :zephyr_file:`include/zephyr/drivers/can.h` to :zephyr_file:`include/zephyr/net/socketcan.h`, the SocketCAN ``struct can_frame`` has been renamed to :c:struct:`socketcan_frame`, and the SocketCAN ``struct can_filter`` has been renamed to :c:struct:`socketcan_filter`. The SocketCAN utility functions are now available in :zephyr_file:`include/zephyr/net/socketcan_utils.h`. * The CAN controller ``struct zcan_frame`` has been renamed to :c:struct:`can_frame`, and ``struct zcan_filter`` has been renamed to :c:struct:`can_filter`. * The :c:enum:`can_state` enumerations have been renamed to contain the word STATE in order to make their context more clear: * ``CAN_ERROR_ACTIVE`` renamed to :c:enumerator:`CAN_STATE_ERROR_ACTIVE`. * ``CAN_ERROR_WARNING`` renamed to :c:enumerator:`CAN_STATE_ERROR_WARNING`. * ``CAN_ERROR_PASSIVE`` renamed to :c:enumerator:`CAN_STATE_ERROR_PASSIVE`. * ``CAN_BUS_OFF`` renamed to :c:enumerator:`CAN_STATE_BUS_OFF`. * The error code for :c:func:`can_send` when the CAN controller is in bus off state has been changed from ``-ENETDOWN`` to ``-ENETUNREACH``. A return value of ``-ENETDOWN`` now indicates that the CAN controller is in :c:enumerator:`CAN_STATE_STOPPED`. * The list of valid return values for the CAN timing calculation functions have been expanded to allow distinguishing between an out of range bitrate/sample point, an unsupported bitrate, and a resulting sample point outside the guard limit. * Memory Management Drivers * Added :c:func:`sys_mm_drv_update_page_flags` and :c:func:`sys_mm_drv_update_region_flags` to update flags associated with memory pages and regions. Removed APIs in this release ============================ * The following functions, macros, and structures related to the deprecated kernel work queue API have been removed: * ``k_work_pending()`` * ``k_work_q_start()`` * ``k_delayed_work`` * ``k_delayed_work_init()`` * ``k_delayed_work_submit_to_queue()`` * ``k_delayed_work_submit()`` * ``k_delayed_work_pending()`` * ``k_delayed_work_cancel()`` * ``k_delayed_work_remaining_get()`` * ``k_delayed_work_expires_ticks()`` * ``k_delayed_work_remaining_ticks()`` * ``K_DELAYED_WORK_DEFINE`` * Removed support for enabling passthrough mode on MPU9150 to AK8975 sensor. * Removed deprecated SPI :c:struct:`spi_cs_control` fields for GPIO management that have been replaced with :c:struct:`gpio_dt_spec`. * Removed support for configuring the CAN-FD maximum DLC value via Kconfig ``CONFIG_CANFD_MAX_DLC``. * Removed deprecated civetweb module and the associated support code and samples. Deprecated in this release ========================== * :c:macro:`DT_SPI_DEV_CS_GPIOS_LABEL` and :c:macro:`DT_INST_SPI_DEV_CS_GPIOS_LABEL` are deprecated in favor of utilizing :c:macro:`DT_SPI_DEV_CS_GPIOS_CTLR` and variants. * :c:macro:`DT_GPIO_LABEL`, :c:macro:`DT_INST_GPIO_LABEL`, :c:macro:`DT_GPIO_LABEL_BY_IDX`, and :c:macro:`DT_INST_GPIO_LABEL_BY_IDX`, are deprecated in favor of utilizing :c:macro:`DT_GPIO_CTLR` and variants. * :c:macro:`DT_LABEL`, and :c:macro:`DT_INST_LABEL`, are deprecated in favor of utilizing :c:macro:`DT_PROP` and variants. * :c:macro:`DT_BUS_LABEL`, and :c:macro:`DT_INST_BUS_LABEL`, are deprecated in favor of utilizing :c:macro:`DT_BUS` and variants. * STM32 LPTIM domain clock should now be configured using devicetree. Related Kconfig :kconfig:option:`CONFIG_STM32_LPTIM_CLOCK` option is now deprecated. * ``label`` property from devicetree as a base property. The property is still valid for specific bindings to specify like :dtcompatible:`gpio-leds` and :dtcompatible:`fixed-partitions`. * Bluetooth mesh Configuration Client API prefixed with ``bt_mesh_cfg_`` is deprecated in favor of a new API with prefix ``bt_mesh_cfg_cli_``. * Pinmux API is now officially deprecated in favor of the pin control API. Its removal is scheduled for the 3.4 release. Refer to :ref:`pinctrl-guide` for more details on pin control. * Flash Map API macros :c:macro:`FLASH_MAP_`, which have been using DTS node label property to reference partitions, have been deprecated and replaced with :c:macro:`FIXED_PARTITION_` which use DTS node label instead. Replacement list: .. table:: :align: center +-----------------------------------+------------------------------------+ \| Deprecated, takes label property \| Replacement, takes DTS node label \| +===================================+====================================+ \| :c:macro:`FLASH_AREA_ID` \| :c:macro:`FIXED_PARTITION_ID` \| +-----------------------------------+------------------------------------+ \| :c:macro:`FLASH_AREA_OFFSET` \| :c:macro:`FIXED_PARTITION_OFFSET` \| +-----------------------------------+------------------------------------+ \| :c:macro:`FLASH_AREA_SIZE` \| :c:macro:`FIXED_PARTITION_SIZE` \| +-----------------------------------+------------------------------------+ \| :c:macro:`FLASH_AREA_LABEL_EXISTS`\| :c:macro:`FIXED_PARTITION_EXISTS` \| +-----------------------------------+------------------------------------+ \| :c:macro:`FLASH_AREA_DEVICE` \| :c:macro:`FIXED_PARTITION_DEVICE` \| +-----------------------------------+------------------------------------+ :c:macro:`FLASH_AREA_LABEL_STR` is deprecated with no replacement as its sole purpose was to obtain the DTS node property label. Stable API changes in this release ================================== New APIs in this release ======================== * CAN * Added :c:func:`can_start` and :c:func:`can_stop` API functions for starting and stopping a CAN controller. Applications will need to call :c:func:`can_start` to bring the CAN controller out of :c:enumerator:`CAN_STATE_STOPPED` before being able to transmit and receive CAN frames. * Added :c:func:`can_get_capabilities` for retrieving a bitmask of the capabilities supported by a CAN controller. * Added :c:enumerator:`CAN_MODE_ONE_SHOT` for enabling CAN controller one-shot transmission mode. * Added :c:enumerator:`CAN_MODE_3_SAMPLES` for enabling CAN controller triple-sampling receive mode. * I3C * Added a set of new API for I3C controllers. * W1 * Introduced the :ref:`W1 api<w1_api>`, used to interact with 1-Wire masters.

USB *** * Minor bug fixes and improvements in class implementations CDC ACM, DFU, and MSC. Otherwise no significant changes. Devicetree ********** * Use of the devicetree label property has been deprecated, and the property has been made optional in almost all bindings throughout the tree. In previous versions of zephyr, label properties like this commonly appeared in devicetree files: .. code-block:: dts foo { label = "FOO"; /* ... / }; You could then use something like the following to retrieve a device structure for use in the :ref:`device_model_api`: .. code-block:: c const struct device my_dev = device_get_binding("FOO"); if (my_dev == NULL) { /* either device initialization failed, or no such device / } else { / device is ready for use / } This approach has multiple problems. First, it incurs a runtime string comparison over all devices in the system to look up each device, which is inefficient since devices are statically allocated and known at build time. Second, missing devices due to misconfigured device drivers could not easily be distinguished from device initialization failures, since both produced ``NULL`` return values from ``device_get_binding()``. This led to frequent confusion. Third, the distinction between the label property and devicetree node labels* -- which are different despite the similar terms -- was a frequent source of user confusion, especially since either one can be used to retrieve device structures. Instead of using label properties, you should now generally be using node labels to retrieve devices instead. Node labels look like the ``lbl`` token in the following devicetree: .. code-block:: dts lbl: foo { /* ... / }; and you can retrieve the device structure pointer like this: .. code-block:: c / If the next line causes a build error, then there * is no such device. Either fix your devicetree or make sure your * device driver is allocating a device. / const struct device my_dev = DEVICE_DT_GET(DT_NODELABEL(lbl)); if (!device_is_ready(my_dev)) { /* device exists, but it failed to initialize / } else { / device is ready for use / } As shown in the above snippet, :c:macro:`DEVICE_DT_GET` should generally be used instead of ``device_get_binding()`` when getting device structures from devicetree nodes. Note that you can pass ``DEVICE_DT_GET`` any devicetree :ref:`node identifier <dt-node-identifiers>` -- you don't have to use :c:macro:`DT_NODELABEL`, though it is usually convenient to do so. Support for devicetree "fixups" was removed. For more details, see `commit b2520b09a7 <path_to_url`_ * :ref:`devicetree_api` * All devicetree macros now recursively expand their arguments. This means that in the following example, ``INDEX`` is always replaced with the number ``3`` for any hypothetical devicetree macro ``DT_FOO()``: .. code-block:: c #define INDEX 3 int foo = DT_FOO(..., INDEX) Previously, devicetree macro arguments were expanded or not on a case-by-case basis. The current behavior ensures you can always rely on macro expansion when using devicetree APIs. * New API macros: * :c:macro:`DT_FIXED_PARTITION_EXISTS` * :c:macro:`DT_FOREACH_CHILD_SEP_VARGS` * :c:macro:`DT_FOREACH_CHILD_SEP` * :c:macro:`DT_FOREACH_CHILD_STATUS_OKAY_SEP_VARGS` * :c:macro:`DT_FOREACH_CHILD_STATUS_OKAY_SEP` * :c:macro:`DT_FOREACH_NODE` * :c:macro:`DT_FOREACH_STATUS_OKAY_NODE` * :c:macro:`DT_INST_CHILD` * :c:macro:`DT_INST_FOREACH_CHILD_SEP_VARGS` * :c:macro:`DT_INST_FOREACH_CHILD_SEP` * :c:macro:`DT_INST_FOREACH_CHILD_STATUS_OKAY_SEP_VARGS` * :c:macro:`DT_INST_FOREACH_CHILD_STATUS_OKAY_SEP` * :c:macro:`DT_INST_FOREACH_CHILD_STATUS_OKAY_VARGS` * :c:macro:`DT_INST_FOREACH_CHILD_STATUS_OKAY` * :c:macro:`DT_INST_STRING_TOKEN_BY_IDX` * :c:macro:`DT_INST_STRING_TOKEN` * :c:macro:`DT_INST_STRING_UPPER_TOKEN_BY_IDX` * :c:macro:`DT_INST_STRING_UPPER_TOKEN_OR` * :c:macro:`DT_INST_STRING_UPPER_TOKEN` * :c:macro:`DT_NODE_VENDOR_BY_IDX_OR` * :c:macro:`DT_NODE_VENDOR_BY_IDX` * :c:macro:`DT_NODE_VENDOR_HAS_IDX` * :c:macro:`DT_NODE_VENDOR_OR` * :c:macro:`DT_STRING_TOKEN_BY_IDX` * :c:macro:`DT_STRING_UPPER_TOKEN_BY_IDX` * :c:macro:`DT_STRING_UPPER_TOKEN_OR` * Deprecated macros: * ``DT_LABEL(node_id)``: use ``DT_PROP(node_id, label)`` instead. This is part of the general deprecation of the label property described at the top of this section. * ``DT_INST_LABEL(inst)``: use ``DT_INST_PROP(inst, label)`` instead. * ``DT_BUS_LABEL(node_id)``: use ``DT_PROP(DT_BUS(node_id), label))`` instead. * ``DT_INST_BUS_LABEL(node_id)``: use ```DT_PROP(DT_INST_BUS(inst), label)`` instead. Similar advice applies for the rest of the following deprecated macros: if you need to access a devicetree node's label property, do so explicitly using another property access API macro. * ``DT_GPIO_LABEL_BY_IDX()`` * ``DT_GPIO_LABEL()`` * ``DT_INST_GPIO_LABEL_BY_IDX()`` * ``DT_INST_GPIO_LABEL()`` * ``DT_SPI_DEV_CS_GPIOS_LABEL()`` * ``DT_INST_SPI_DEV_CS_GPIOS_LABEL()`` * ``DT_CHOSEN_ZEPHYR_FLASH_CONTROLLER_LABEL`` * Bindings * The :ref:`bus <dt-bindings-bus>` key in a bindings file can now be a list of strings as well as a string. This allows a single node to declare that it represents hardware which can communicate over multiple bus protocols. The primary use case is simultaneous support for I3C and I2C buses in the same nodes, with the base bus definition provided in :zephyr_file:`dts/bindings/i3c/i3c-controller.yaml`. * New: *

See `commit 0224f2c508df154ffc9c1ecffaf0b06608d6b623 <path_to_url`_ Libraries / Subsystems ********************** * C Library * Added Picolibc as a Zephyr module. Picolibc module is a footprint-optimized full C standard library implementation that is configurable at the build time. * C library heap initialization call has been moved from the ``APPLICATION`` phase to the ``POST_KERNEL`` phase to allow calling the libc dynamic memory management functions (e.g. ``malloc()``) during the application initialization phase. * Added ``strerror()`` and ``strerror_r()`` functions to the minimal libc. * Removed architecture-specific ``off_t`` type definition in the minimal libc. ``off_t`` is now defined as ``intptr_t`` regardless of the selected architecture. * C++ Subsystem * Added ``std::ptrdiff_t``, ``std::size_t``, ``std::max_align_t`` and ``std::nullptr_t`` type definitions to the C++ subsystem ``cstddef`` header. * Renamed global constructor list symbols to prevent the native POSIX host runtime from executing the constructors before Zephyr loads. * Cbprintf * Updated cbprintf static packaging to interpret ``unsigned char `` as a pointer to a string. See :ref:`cbprintf_packaging_limitations` for more details about how to efficienty use strings. Change mainly applies to the ``logging`` subsystem since it uses this feature. Emul * Added :c:macro:`EMUL_DT_DEFINE` and :c:macro:`EMUL_DT_INST_DEFINE` to mirror :c:macro:`DEVICE_DT_DEFINE` and :c:macro:`DEVICE_DT_INST_DEFINE` respectively. * Added :c:macro:`EMUL_DT_GET` to mirror :c:macro:`DEVICE_DT_GET`. * Removed the need to manually register emulators in their init function (automatically done). * Filesystem * Added cash used to reduce the NVS data lookup time, see :kconfig:option:`CONFIG_NVS_LOOKUP_CACHE` option. * Changing mkfs options to create FAT32 on larger storage when FAT16 fails. * Added :kconfig:option:`CONFIG_FS_FATFS_MIN_SS` that allows to set minimal expected sector size to be supported. * Management * MCUMGR race condition when using the task status function whereby if a thread state changed it could give a falsely short process list has been fixed. * MCUMGR shell (group 9) CBOR structure has changed, the ``rc`` response is now only used for mcumgr errors, shell command execution result codes are instead returned in the ``ret`` variable instead, see :ref:`mcumgr_smp_group_9` for updated information. Legacy behaviour can be restored by enabling :kconfig:option:`CONFIG_MCUMGR_CMD_SHELL_MGMT_LEGACY_RC_RETURN_CODE`. * MCUMGR img_mgmt erase command now accepts an optional slot number to select which image will be erased, using the ``slot`` input (will default to slot 1 if not provided). * MCUMGR :kconfig:option:`CONFIG_OS_MGMT_TASKSTAT_SIGNED_PRIORITY` is now enabled by default, this makes thread priorities in the taskstat command signed, which matches the signed priority of tasks in Zephyr, to revert to previous behaviour of using unsigned values, disable this Kconfig. * MCUMGR taskstat runtime field support has been added, if :kconfig:option:`CONFIG_OS_MGMT_TASKSTAT` is enabled, which will report the number of CPU cycles have been spent executing the thread. * MCUMGR transport API drops ``zst`` parameter, of :c:struct:`zephyr_smp_transport` type, from :c:func:`zephyr_smp_transport_out_fn` type callback as it has not been used, and the ``nb`` parameter, of :c:struct:`net_buf` type, can carry additional transport information when needed. * A dummy SMP transport has been added which allows for testing MCUMGR functionality and commands/responses. * An issue with the UART/shell transports whereby large packets would wrongly be split up with multiple start-of-frame headers instead of only one has been fixed. * SMP now runs in its own dedicated work queue which prevents issues running in the system workqueue with some transports, e.g. Bluetooth, which previously caused a deadlock if buffers could not be allocated. * Bluetooth transport will now reduce the size of packets that are sent if they are too large for the remote device instead of failing to send them, if the remote device cannot accept a notification of 20 bytes then the attempt is aborted. * Unaligned memory access problems for CPUs that do not support it in MCUMGR headers has been fixed. * Groups in MCUMGR now use kernel slist entries rather than the custom MCUMGR structs for storage. * Levels of function redirection which were previously used to support multiple OS's have been reduced to simplify code and reduce output size. * Bluetooth SMP debug output format specifier has been fixed to avoid a build warning on native_posix platforms. * Issue with :c:func:`img_mgmt_dfu_stopped` being wrongly called on success has been fixed. * Issue with MCUMGR img_mgmt image erase wrongly returning success during an error condition has been fixed. * Unused MCUMGR header files such as mcumgr_util.h have been removed. * Verbose error response reporting has been fixed and is now present when enabled. * Internal SMP functions have been removed from the public smp.h header file and moved to smp_internal.h * Kconfig files have been split up and moved to directories containing the systems they influence. * MCUMGR img_mgmt image upload over-riding/hiding of result codes has been fixed. * Logging * Removed legacy (v1) implementation and removed any references to the logging v2. * Added :c:macro:`LOG_RAW` for logging strings without additional formatting. It is similar to :c:macro:`LOG_PRINTK` but do not append ``<cr>`` when new line is found. * Improvements in the ADSP backend. * File system backend: Only delete old files if necessary. * IPC * Introduced a 'zephyr,buffer-size' DT property to set the sizes for TX and RX buffers per created instance. * Set WQ priority back to ``PRIO_PREEMPT`` to fix an issue that was starving the scheduler. * ``icmsg_buf`` library was renamed to ``spsc_pbuf``. * Added cache handling support to ``spsc_pbuf``. * Fixed an issue where the TX virtqueue was misaligned by 2 bytes due to the way the virtqueue start address is calculated * Added :c:func:`ipc_service_deregister_endpoint` function to deregister endpoints. * LoRaWAN * Added Class-C support. * Upgraded the loramac-node repository to v4.6.0. * Moved the ``REQUIRES_FULL_LIBC`` library dependency from LoRa to LoRaWAN. * Fixed the async reception in SX127x modems. * Modbus * Added user data entry for ADU callback. * Power management * Allow multiple subscribers to latency changes in the policy manager. * Added new API to implement suspend-to-RAM (S2RAM). Select :kconfig:option:`CONFIG_PM_S2RAM` to enable this feature. * Added :c:func:`pm_device_is_powered` to query a device power state. * POSIX * Made ``tz`` non-const in ``gettimeofday()`` for conformance to spec. * Fixed pthread descriptor resource leak. Previously only pthreads with state ``PTHREAD_TERMINATED`` could be reused. However, ``pthread_join()`` sets the state to ``PTHREAD_EXITED``. Consider both states as candidates in ``pthread_create()``. * Added ``perror()`` implementation. * Used consistent timebase in ``sem_timedwait()``. * RTIO * Initial version of an asynchronous task and executor API for I/O similar inspired by Linux's very successful io_uring. * Provided a simple linear and limited concurrency executor, simple task queuing, and the ability to poll for task completions. * SD Subsystem * SDMMC STM32: Now compatible with STM32L5 series. Added DMA support for DMA-V1 compatible devices. * Added support for handling the :c:macro:`DISK_IOCTL_CTRL_SYNC` ioctl call. this enables the filesystem api :c:func:`fs_sync`. * Settings * Added API function :c:func:`settings_storage_get` which allows to get the storage instance used by the settings backed to store its records. * Shell * Added new API function checking shell readiness: :c:func:`shell_ready`. * Added option to control formatting of the logging timestamp. * Added missing asserts to the shell api functions. * MQTT backend: bug fix to handle negative return value of the wait function. * A new ``backends`` command that lists the name and number of active shell backends. * Fixed handling mandatory args with optional raw arg. * Storage * :c:func:`flash_area_open` returns error if area's flash device is unreachable. * ``flash_area`` components were reworked so build-time reference to the flash device is used instead of its name with runtime driver buinding. * Added ``FIXED_PARTITION_`` macros that move flash_map to use DTS node labels. * Testsuite * Added Kconfig support to ``unit_testing`` platform. * Migrated tests to use :kconfig:option:`CONFIG_ZTEST_NEW_API`. * Added ztest options for shuffling tests/suites via: * :kconfig:option:`CONFIG_ZTEST_SHUFFLE` * :kconfig:option:`CONFIG_ZTEST_SHUFFLE_SUITE_REPEAT_COUNT` * :kconfig:option:`CONFIG_ZTEST_SHUFFLE_TEST_REPEAT_COUNT` * Added ztest native_posix command line arguments for running specific tests/suites using ``--test suite_name:`` or ``--test suite_name::test_name`` command line arguments. Storage * Flash Map API deprecates usage of :c:macro:`FLASH_AREA_` macros and replaces them with :c:macro:`FIXED_PARTITION_` macros. This follows removal of ``label`` property from DTS nodes.
