[PATCH 1/2] drm/amdgpu: Allow switching to CUSTOM profile on Vega10

[Russell, Kent]

Don't return an error if the CUSTOM profile is selected, just apply it
with the values saved to the GPU. But ensure that we zero out the
copy stored in adev to ensure that a valid profile has been submitted at
some point first

[PATCH 2/2] drm/amdgpu: Allow switching to CUSTOM profile on Vega20

[Russell, Kent]

Vega20 stores a CUSTOM profile on the GPU, but it may not be valid. Add
a bool to vega20_hwmgr to determine whether or not a valid CUSTOM
profile has been set, and use that to check when a user requests
switching to the CUSTOM profile without passing in any arguments. Then
if the CUSTOM profile has been set already, we can switch to it without
providing the parameters again

[PATCH 2/2] drm/amdgpu: Allow switching to CUSTOM profile on Vega20

[Russell, Kent]

Vega20 stores a CUSTOM profile on the GPU, but it may not be valid. Add
a bool to vega20_hwmgr to determine whether or not a valid CUSTOM
profile has been set, and use that to check when a user requests
switching to the CUSTOM profile without passing in any arguments. Then
if the CUSTOM profile has been set already, we can switch to it without
providing the parameters again
