drm/amd/pm: avoid duplicate powergate/ungate setting

2021-11-22T19:45:02Z

Just bail out if the target IP block is already in the desired powergate/ungate state. This can avoid some duplicate settings which sometimes may cause unexpected issues.

drm/amd/display: Enable PSR by default on newer DCN

2021-10-13T18:14:34Z

[Why] For optimal power savings on panels that can support it. This was previously left disabled by default because of issues with compositors that do not pageflip and scan out directly to the frontbuffer. For these compositors we now have detection methods that wait for x number of pageflips after a full update - triggered by a buffer or format change typically. This may introduce bugs or new cases not tested by users so this is only currently targeting newer DCN. [How] Add code in DM to set PSR state by default for newer DCN while falling back to the feature mask for older. Add a global debug flag that can be set to disable it for either.
