drm/amd/display: disable FPO and SubVP for older DMUB versions on DCN32x

2023-12-19T20:20:57+00:00

There have recently been changes that break backwards compatibility, that were introduced into DMUB firmware (for DCN32x) concerning FPO and SubVP. So, since those are just power optimization features, we can just disable them unless the user is using a new enough version of DMUB firmware.

drm/amd/display: fix hw rotated modes when PSR-SU is enabled

2023-12-11T17:41:05+00:00

We currently don't support dirty rectangles on hardware rotated modes. So, if a user is using hardware rotated modes with PSR-SU enabled, use PSR-SU FFU for all rotated planes (including cursor planes).
