drm/amd/display: Don't show stack trace for missing eDP

2023-08-16T16:32:26+00:00

commit 7ad1dfc144cbf62702fd07838da8fd8a77921083 upstream. Some systems are only connected by HDMI or DP, so warning related to missing eDP is unnecessary. Downgrade to debug instead.

drm/amd/display: check attr flag before set cursor degamma on DCN3+

2023-08-16T16:32:19+00:00

commit 96b020e2163fb2197266b2f71b1007495206e6bb upstream. Don't set predefined degamma curve to cursor plane if the cursor attribute flag is not set. Applying a degamma curve to the cursor by default breaks userspace expectation. Checking the flag before performing any color transformation prevents too dark cursor gamma in DCN3+ on many Linux desktop environment (KDE Plasma, GNOME, wlroots-based, etc.) as reported at: - https://gitlab.freedesktop.org/drm/amd/-/issues/1513 This is the same approach followed by DCN2 drivers where the issue is not present.

drm/amd/display: Prevent vtotal from being set to 0

[How] Only set vtotal to the crtc adjustment vtotal_min value in cases where the value is non-zero.

drm/amd/display: update extended blank for dcn314 onwards

2023-08-03T08:25:46+00:00

[ Upstream commit 469a62938a45ef382c9cb7b9fec6c6c1fcd781c0 ] [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.
