Interesting, am not facing this issue. Do you have atomic operations
enabled?
I think its not hence you are facing this issue. Perhaps can you try
enabling it and then check.
However, will it appropriate to use amdgpu_bo_pin() instead of
amdgpu_bo_gpu_offset()?
As i notice same being used in dce_v11_0.c for non-atomic scenarios.
Regards,
Shirish S
