2023-04-25Revert "drm/amd/display: disable SubVP + DRR to prevent underflow"Aurabindo Pillai2-9/+0
This reverts commit 80c6d6804f31451848a3956a70c2bcb1f07cfcb0. The orignal commit was intended as a workaround to prevent underflow and flickering when using one normal monitor and the other high refresh rate monitor (> 120Hz).

2023-04-25drm/amd/display: update extended blank for dcn314 onwardsGabe Teeger8-57/+29
[Why] Flickering and underflow was observed when testing extended blank on dcn314. [What] Vstartup is contrainted by vblank_nom, so adjusting it to include non-adjusted vtotal in its calculation during freesync video means that Vstartup is not changed when vtotal changes. This fixed the flickering + underflow. dc_extended_blank_supported function was removed because extended blank is only relevant to when zstate is supported. The increased vtotal during freesync can be passed to dml regardless of whether extended blank is supported or not, so this function is not needed. Updates were made recently in dml to the calculation of min_dst_y_next_start. Dml input for dcn314 will now always use the newer calculation for min_dst_y_next_start. Dml input for older dcn versions remains untouched. The variable optimized_min_dst_y_next_start is replaced everywhere with min_dst_y_next_start, and the updated dml allows min_dst_y_next_start to increase to an optimized value during freesync video, then return to default when freesync is disengaged. Also removed registry key for controlling extended blank feature.

2023-04-25drm/amd/display: Program OTG vtotal min/max selectors unconditionallyAurabindo Pillai1-9/+2
OTG_V_TOTAL_MIN/MAX_SEL bits are required to be programmed to 1 if writes to OTG timing registers need to be honoured. This is usually needed only when freesync is active. However, SubVP + DRR requires that we're able to change timing even without freesync being active (but supported). By unconditionally writing this bit to 1, we remove an unnecessary dependency so that DMCUB can change OTG timing whenever it wants.

2023-04-21drm/amd/display: fix flickering caused by S/G modeHamza Mahfooz1-2/+11
Currently, on a handful of ASICs. We allow the framebuffer for a given plane to exist in either VRAM or GTT. However, if the plane's new framebuffer is in a different memory domain than it's previous framebuffer, flipping between them can cause the screen to flicker. So, to fix this, don't perform an immediate flip in the aforementioned case.
