Bananymous	a08b9b82a6	Kernel: Fix yield stack pointer value Stack pointer was pointing to value of return address on return instead of past it. This did not affect anything as ig Processor::yield() didn't use stack after calling the trampoline	2026-01-19 00:47:00 +02:00
Bananymous	35c97e2ff8	Kernel: optimize yielding Doing a yield no longer raises a software interrupt. Instead it just saves all the callee saved registers, ip, sp and return value. Because yield is only called in the kernel, it can just restore registers and jump to the target address. There is never a need to use iret :)	2026-01-11 01:31:09 +02:00

Kernel: Fix yield stack pointer value

Stack pointer was pointing to value of return address on return instead
of past it. This did not affect anything as ig Processor::yield() didn't
use stack after calling the trampoline

Kernel: optimize yielding

Doing a yield no longer raises a software interrupt. Instead it just
saves all the callee saved registers, ip, sp and return value. Because
yield is only called in the kernel, it can just restore registers and
jump to the target address. There is never a need to use iret :)
