Hey Christian, very interesting idea! I've tested it alone (without patch 2) and was able to see the PSP code freeing buffers during suspend, leading to a resume failure later. Feel free to add my: Tested-by: Guilherme G. Piccoli Cheers, Guilherme

[PATCH 3/3] drm/amdgpu: WARN when freeing kernel memory during suspend

2022-11-16 Thread Christian König
When buffers are freed during suspend there is no guarantee that they can be re-allocated during resume. The PSP subsystem seems to be quite buggy regarding this, so add a WARN_ON() to point out those bugs. Signed-off-by: Christian König --- drivers/gpu/drm/amd/amdgpu/amdgpu_object.c | 2 ++ 1
