Subject: drm/amdgpu/swsmu: default to fullscreen 3D profile for dGPUs
|
||
|
|
|
||
|
|
This uses more aggressive hueristics than the the bootup default
|
||
|
|
profile. On windows the OS has a special fullscreen 3D mode
|
||
|
|
where this is used. Since we don't have the equivalent on Linux
|
||
|
|
default to this profile for dGPUs.
