Hi, Christian
Thanks for you patch .Those patches can fix amdgpu bo pinned failed issue during perform dm_plane_helper_prepare_fb
and Abaqus performance seems improved.
But there some error message can be observer. Do we need drop amdgpu_vm_validate_pt_bos() error message
and other warning debug info .

Subject: [PATCH 10/10] drm/amdgpu: stop removing BOs from the LRU v3
[CAUTION: External Email]
This avoids OOM situations when we have lots of threads submitting at the same time.
v3: apply this to the whole driver, not just CS
