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
