/*
* ARM64/aarch64 context switching for kcoro
*
* This file implements the low-level register/stack switch primitive `kcoro`:
* void* kcoro(kcoro_t* from_co, kcoro_t* to_co);
*
* Conceptually:
* - Save the current coroutine's callee-saved registers and stack pointer
* into from_co->reg[]
* - Restore the target coroutine's registers and stack pointer from
* to_co->reg[]
* - Branch to to_co->reg[RETADDR] (the saved continuation / entry point)
*
* Stack model:
* libkcoro uses a shared stack. Higher-level C code copies the active slice
* of the stack between a coroutine-private save buffer and the shared stack
* before/after calling `kcoro`. This assembly switches only registers and SP.
*
* Register layout in kcoro_t.reg for ARM64 (indices into void* reg[32]):
* reg[ 0.. 9] : x19..x28 (callee-saved)
* reg[15] : x29 (frame pointer)
* reg[13] : x30 (return addr) (a.k.a. link register / continuation)
* reg[14] : sp (stack pointer)
*
* Byte offsets = index * 8 (because reg[] is an array of void* on 64-bit):
* x19 @ 0x00 (reg[0]) ... x28 @ 0x48 (reg[9])
* x30 @ 0x68 (reg[13])
* sp @ 0x70 (reg[14])
* x29 @ 0x78 (reg[15])
*
* ABI notes:
* - ARM64 requires 16-byte stack alignment on public interfaces. The C
* runtime sets up align_retptr accordingly; this routine preserves SP.
* - We only touch callee-saved registers; caller-saved regs/args are the
* responsibility of the surrounding C code.
* - We do not save/restore FP/SIMD state here; libkcoro avoids using it on
* ARM64 (kcoro_save_fpucw_mxcsr is a no-op stub).
*

* Inspired by work done on libkcoro, Sen Han <00hnes@gmail.com>

* x86_64 System V context switching for kcoro
*
* Implements the low-level primitive:
* void* kcoro_switch(kcoro_t* from_co, kcoro_t* to_co);
*
* Contract (matches kcoro_core.c expectations):
* kcoro_t has `void* reg[32]` as its first field. Indices used on x86_64:
* reg[ 0..5] : r12, r13, r14, r15, rbx, rbp (callee-saved)
* reg[13] : rip (continuation to jump/return to)
* reg[14] : rsp (stack pointer)
* reg[15] : rbp (frame/base pointer)
*
* Save from_co's callee-saved regs, RIP (from [rsp]), and RSP/RBP.
* Restore to_co's RSP/RBP and callee-saved regs, then transfer control to
* its saved continuation. To make the continuation look like a normal call
* target w.r.t. ABI stack alignment, we push the saved rip and `ret` to it.
*
* Notes:
* - System V AMD64: caller ensures 16-byte alignment before `call`. At function
* entry, after the return address is pushed, RSP % 16 == 8. By pushing the
* saved continuation and using `ret`, we preserve the expected entry state.
* - We do not save/restore XMM/FPU state here; kcoro avoids relying on it across
* switches (mirrors the ARM64 implementation policy).

/*
* ARM64/aarch64 context switching for kcoro
*
* This file implements the low-level register/stack switch primitive `kcoro`:
* void* kcoro(kcoro_t* from_co, kcoro_t* to_co);
*
* Conceptually:
* - Save the current coroutine's callee-saved registers and stack pointer
* into from_co->reg[]
* - Restore the target coroutine's registers and stack pointer from
* to_co->reg[]
* - Branch to to_co->reg[RETADDR] (the saved continuation / entry point)
*
* Stack model:
* libkcoro uses a shared stack. Higher-level C code copies the active slice
* of the stack between a coroutine-private save buffer and the shared stack
* before/after calling `kcoro`. This assembly switches only registers and SP.
*
* Register layout in kcoro_t.reg for ARM64 (indices into void* reg[32]):
* reg[ 0.. 9] : x19..x28 (callee-saved)
* reg[15] : x29 (frame pointer)
* reg[13] : x30 (return addr) (a.k.a. link register / continuation)
* reg[14] : sp (stack pointer)
*
* Byte offsets = index * 8 (because reg[] is an array of void* on 64-bit):
* x19 @ 0x00 (reg[0]) ... x28 @ 0x48 (reg[9])
* x30 @ 0x68 (reg[13])
* sp @ 0x70 (reg[14])
* x29 @ 0x78 (reg[15])
*
* ABI notes:
* - ARM64 requires 16-byte stack alignment on public interfaces. The C
* runtime sets up align_retptr accordingly; this routine preserves SP.
* - We only touch callee-saved registers; caller-saved regs/args are the
* responsibility of the surrounding C code.
* - We do not save/restore FP/SIMD state here; libkcoro avoids using it on
* ARM64 (kcoro_save_fpucw_mxcsr is a no-op stub).
*

/*
* x86_64 System V context switching for kcoro
*
* Implements the low-level primitive:
* void* kcoro_switch(kcoro_t* from_co, kcoro_t* to_co);
*
* Contract (matches kcoro_core.c expectations):
* kcoro_t has `void* reg[32]` as its first field. Indices used on x86_64:
* reg[ 0..5] : r12, r13, r14, r15, rbx, rbp (callee-saved)
* reg[13] : rip (continuation to jump/return to)
* reg[14] : rsp (stack pointer)
* reg[15] : rbp (frame/base pointer)
*
* Save from_co's callee-saved regs, RIP (from [rsp]), and RSP/RBP.
* Restore to_co's RSP/RBP and callee-saved regs, then transfer control to
* its saved continuation. To make the continuation look like a normal call
* target w.r.t. ABI stack alignment, we push the saved rip and `ret` to it.
*
* Notes:
* - System V AMD64: caller ensures 16-byte alignment before `call`. At function
* entry, after the return address is pushed, RSP % 16 == 8. By pushing the
* saved continuation and using `ret`, we preserve the expected entry state.
* - We do not save/restore XMM/FPU state here; kcoro avoids relying on it across
* switches (mirrors the ARM64 implementation policy).

# IPI from the boot CPU. Section B.4.2 of the Multi-Processor
# Specification says that the AP will start in real mode with CS:IP
# set to XY00:0000, where XY is an 8-bit value sent with the
# STARTUP. Thus this code must start at a 4096-byte boundary.
#
# Because this code sets DS to zero, it must sit
