drm/amd/display: Blocking invalid 420 modes on HDMI TMDS for DCN314

2023-09-23T09:14:25Z

[ Upstream commit 4c6107a653ccf361cb1b6ba35d558a1a5e6e57ac ] [Why & How] HDMI TMDS does not have ODM support. Filtering 420 modes that exceed the 4096 FMT limitation on DCN314 will resolve intermittent corruptions issues.

drm/amd/display: limit the v_startup workaround to ASICs older than DCN3.1

2023-09-19T10:30:25Z

commit 47428f4b638d3b3264a2efa1a567b0bbddbb6107 upstream. Since, calling dcn20_adjust_freesync_v_startup() on DCN3.1+ ASICs can cause the display to flicker and underflow to occur, we shouldn't call it for them. So, ensure that the DCN version is less than DCN_VERSION_3_1 before calling dcn20_adjust_freesync_v_startup().

Revert "drm/amd/display: Remove v_startup workaround for dcn3+"

2023-09-19T10:30:25Z

commit a81de4a22bbe3183b7f0d6f13f592b8f5b5a3c18 upstream. This reverts commit 3a31e8b89b7240d9a17ace8a1ed050bdcb560f9e. We still need to call dcn20_adjust_freesync_v_startup() for older DCN3+ ASICs. Otherwise, it can cause DP to HDMI 2.1 PCONs to fail to light up.

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

2023-07-18T18:40:56Z

[Why] In dcn314 DML the destination pipe vtotal was being set to the crtc adjustment vtotal_min value even in cases where that value is 0. [How] Only set vtotal to the crtc adjustment vtotal_min value in cases where the value is non-zero.
