drm/amdgpu: move vmhub out of amdgpu_ring_funcs (v4)

2023-04-14T17:47:49+00:00

It looks better to place this field in ring
structure. Also drop the repeated ring funcs definitions
if there's no difference except for vmhub field.

v2: rename the field to vm_hub like others (Le)
v3: apply the changes to new ip blocks (Hawking)
v4: fix vcn sw ring (Alex)

2022-12-14T14:48:32+00:00

2022-12-14T14:48:32+00:00

Bas pointed out that this isn't working as expected and could cause

inside the job instead.
