BORE: Crash, when switching often BORE off and on

[mabod]

yesterday I compiled cachyos 6.13.1 and got this warning during compilation.

ld.lld: warning: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6714:0: stack frame size (2056) exceeds limit (2048) in function 'dml_core_mode_support'

This was with clang and lto=thin which is the default now.

After that I wanted to do some performance resp. latency tests as described in the video: https://www.youtube.com/watch?v=kKumW_qH4a0
from the BORE developer @firelzrd

After a hand full of sysctl -w kernel.sched_bore=0 / sysctl -w kernel.sched_bore=1 cycles my PC frooze completey. Sound was looping and not even a REISUB was possible.

This is the journal

[hellsgod]

It probably happened, because you switched scheduler in the process. Yes, I know, it's done in the video, but a crash can happen because of that. It happened in "pick_task_fair", so maybe a task was already planned for BORE, you switched back to "EEVDF" and this task was not fully migrated back to EEVDF in the switch and you got your kaboom. It's just a guess. Use the kernel in your day to day usage and see, if it happens there, too.

yesterday I compiled cachyos 6.13.1 and got this warning during compilation.

ld.lld: warning: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6714:0: stack frame size (2056) exceeds limit (2048) in function 'dml_core_mode_support'

This is a known issue with LLVM19. AFAIK a fix was already staged in amd-drm-staging-next and will probably in a future stable kernel soon.

[mabod]

But what does this message tell me? Is it save to use this kernel or is this stack limit issue a concern for system stability?

[ptr1337]

But what does this message tell me? Is it save to use this kernel or is this stack limit issue a concern for system stability?

Its just a compiler warning - not more. This has nothing to do with the system stability.
