-Subject: [PATCH 1608/4131] drm/amdgpu: Ignore eviction fence during unmap
-
-Remove eviction fence from PD (and thereby from PTs too as they share
-the resv. object. Otherwise during PT update job (see
-amdgpu_vm_bo_update_mapping), eviction fence will get added to job->sync
-object. This will trigger unnecessary evictions when the scheduler tries
-to execute the job.
-
-This change will also enable to revert the temporary
-commit 6bb00e491bfb ("drm/amdgpu: Use AMDGPU_FENCE_OWNER_VM in unmap")
