Comment 24 for bug 1798165

This might just be my lack of familiarity with the codebase, but why is ANV affected by this while RADV is not? I do not have any hardware to use to study how RADV works, but at a glance, it is relatively easy to see the fence bits being handled in the i915 GEM code while I am unable to tell at a glance how the amdgpu GEM code uses them. It seems to be done in a very abstract way in the amdgpu_cs.c file and it is not clear to me how that gets invoked by RADV. I am curious if the difference might point to the possibility that ANV is overly aggressive at fencing. I believe that DXVK should be making the same API calls on both.
