Subject: 6.10/regression/bisected - commit a68c7eaa7a8f cause *ERROR* Trying
to clear memory with ring turned off in amdgpu_fill_buffer.
Hi,
I am continuing to test unstable kernels.
Yesterday at Fedora Rawhide arrived the new kernel
20240516git3c999d1ae3c7 and I spotted in kernel log new error message:
[ 13.676117] [drm] Seamless boot condition check passed
[ 13.676996] [drm:amdgpu_fill_buffer [amdgpu]] *ERROR* Trying to
clear memory with ring turned off.

drm/amdgpu: Enable clear page functionality
Add clear page support in vram memory region.
v1(Christian):
- Dont handle clear page as TTM flag since when moving the BO back
in from GTT again we don't need that.
- Make a specialized version of amdgpu_fill_buffer() which only
clears the VRAM areas which are not already cleared
- Drop the TTM_PL_FLAG_WIPE_ON_RELEASE check in
amdgpu_object.c
v2:
- Modify the function name amdgpu_ttm_* (Alex)
- Drop the delayed parameter (Christian)
- handle amdgpu_res_cleared(&cursor) just above the size
calculation (Christian)
- Use AMDGPU_GEM_CREATE_VRAM_WIPE_ON_RELEASE for clearing the buffers
in the free path to properly wait for fences etc.. (Christian)
v3(Christian):
- Remove buffer clear code in VRAM manager instead change the
AMDGPU_GEM_CREATE_VRAM_WIPE_ON_RELEASE handling to set
the DRM_BUDDY_CLEARED flag.
- Remove ! from amdgpu_res_cleared(&cursor) check.
v4(Christian):
- vres flag setting move to vram manager file
- use dma_fence_get_stub in amdgpu_ttm_clear_buffer function
- make fence a mandatory parameter and drop the if and the get/put dance
