Re: [PATCH] drm/amdgpu: Fix code with incorrect enum type

[Григорий]

Alex Deucher I will do it. Initially, I came across an error that
different enum types are used.
Now I looked at the files, and indeed AMDGPU_GFX_PIPE_PRIO_* is used
instead of AMDGPU_RING_PRIO_*.
The question remains whether it is worth increasing the priority to
AMDGPU_RING_PRIO_MAX=3 ?

Regards, Grigory.
