[PATCH] printk: add early_counter_ns routine for printk blind spot
From: Tim Bird <tim.bird@sony.com> During early boot, printk timestamps are reported as zero, which creates a blind spot in early boot timings. This blind spot hinders timing and optimization efforts for code that executes before time_init(), which is when local_clock() is initialized sufficiently to start returning ...

During early boot, printk timestamps are reported as zero before kernel timekeeping starts (e.g. before time_init()). This hinders boot-time optimization efforts. This period is about 400 milliseconds for many current desktop and embedded machines running Linux. Add support to save cycles during early boot, and outp...

Hi Tim, I tested this both on X86_64 QEMU and on a i.MX93 (ARM64) and can confirm it is working as expected. Auto-calc of calibration data is far better than the configuration parameters in v1. It is slightly confusing to see a time value printed to serial output and another one inside kmsg, but that's a human thing ...

Agreed. I wasn't too worried about it, because most serious developers working on boot-time will not be watching early messages over serial console. (Usually they use 'quiet' or some lower log level). But on qemu, it does look strange to see 0s on the first output sequence, and then non-zeroes when using dmesg la...

I'll look at this. Is BIT_ULL(63) preferred over (1ULL << 63)? Do you think something like "HIGH_BIT63" would be good enough? OK. I did not know about that. I can check, but do you know offhand if timestamps from local_clock() on 32-bit systems are always 64-bit nanoseconds? I assume so looking at the prin...

[PATCH 0/4] ASoC: ti: davinci-mcasp: Add asynchronous mode support for McASP
This series adds asynchronous mode support to the McASP driver, which enables independent configuration of bitclocks, frame sync, and audio configurations between tx(playback) and rx(record). And achieves simultaneous playback & record using different audio configurations. It also adds two clean up patches to the McAS...
Simplify the mcasp_set_clk_pdir caller convention in start/stop stream function, to make it so that set_clk_pdir gets called regardless when stream starts and also disables when stream ends. Functionality-wise, everything remains the same as the previously skipped calls are now either correctly configured (when McASP ...

The current mcasp_is_synchronous() function does more than what it proclaims, it also checks if McASP is a frame producer. Therefore split the original function into two separate ones and replace all occurrences with the new equivalent logic. So the functions can be re-used when checking async/sync status in light of ...

McASP supports the independent configuration of TX & RX clk and frame sync registers. By default, the driver is configured in synchronous mode where RX clock generator is disabled and it uses transmit clock signals as bit clock and frame sync. Therefore add optional properties needed for asynchronous mode. Add ti,asyn...

Calculate the SHA256 hash for blacklisting purposes independently of the signature hash (which may be something other than SHA256).
