drm/amd/display: Fix green screen issue after suspend

2020-05-06T06:16:15+00:00

commit 87b7ebc2e16c14d32a912f18206a4d6cc9abc3e8 upstream. [why] We have seen a green screen after resume from suspend in a Raven system connected with two displays (HDMI and DP) on X based system. We noticed that this issue is related to bad DCC metadata from user space which may generate hangs and consequently an underflow on HUBP. After taking a deep look at the code path we realized that after resume we try to restore the commit with the DCC enabled framebuffer but the framebuffer is no longer valid. [how] This problem was only reported on Raven based system and after suspend, for this reason, this commit adds a new parameter on fill_plane_dcc_attributes() to give the option of disabling DCC programmatically. In summary, for disabling DCC we first verify if is a Raven system and if it is in suspend; if both conditions are true we disable DCC temporarily, otherwise, it is enabled.

drm/amd/display: Calculate scaling ratios on every medium/full update

2020-04-29T14:34:34+00:00

[ Upstream commit 3bae20137cae6c03f58f96c0bc9f3d46f0bc17d4 ] [Why] If a plane isn't being actively enabled or disabled then DC won't always recalculate scaling rects and ratios for the primary plane. This results in only a partial or corrupted rect being displayed on the screen instead of scaling to fit the screen. [How] Add back the logic to recalculate the scaling rects into dc_commit_updates_for_stream since this is the expected place to do it in DC. This was previously removed a few years ago to fix an underscan issue but underscan is still functional now with this change - and it should be, since this is only updating to the latest plane state getting passed in.

[ Upstream commit 346d8a0a3c91888a412c2735d69daa09c00f0203 ] [Why] After v_total_min and max are updated in vrr structure, the changes are not reflected in stream adjust. When these values are read from stream adjust it does not reflect the actual state of the system. [How] Set stream adjust values equal to vrr adjust values after vrr adjust values are updated.

drm/amd/display: Don't try hdcp1.4 when content_type is set to type1

[ Upstream commit c2850c125d919efbb3a9ab46410d23912934f585 ] [Why] When content type property is set to 1. We should enable hdcp2.2 and if we cant then stop. Currently the way it works in DC is that if we fail hdcp2, we will try hdcp1 after. [How] Use link config to force disable hdcp1.4 when type1 is set.
