X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=13524856336dfd055a8c7c5b4e5524553a12e938;p=linux.git

drm/amd/display: setup system context for APUs

[Why]
Scatter/gather is APU feature.
But in dm it is limited only to Renoir.
Now we need it for Vangogh.

[How]
Apply system context setup in dm_init to all APUs.
