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.

drm/amd/display: Update stream adjust in dc_stream_adjust_vmin_vmax

2020-04-29T14:34:28+00:00

[ 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

2020-04-23T08:38:11+00:00

[ 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.

drm/amdgpu: fix the hw hang during perform system reboot and reset

2020-04-21T07:08:12+00:00

commit b2a7e9735ab2864330be9d00d7f38c961c28de5d upstream.

The system reboot failed as some IP blocks enter power gate before perform
hw resource destory. Meanwhile use unify interface to set device CGPG to ungate
state can simplify the amdgpu poweroff or reset ungate guard.

drm/amdgpu: fix gfx hang during suspend with video playback (v2)

[ Upstream commit 487eca11a321ef33bcf4ca5adb3c0c4954db1b58 ]

The system will be hang up during S3 suspend because of SMU is pending
for GC not respose the register CP_HQD_ACTIVE access request.This issue
root cause of accessing the GC register under enter GFX CGGPG and can
be fixed by disable GFX CGPG before perform suspend.

v2: Use disable the GFX CGPG instead of RLC safe mode guard.

drm/amd/display: Check for null fclk voltage when parsing clock table

2020-04-17T14:13:42+00:00

commit 72f5b5a308c744573fdbc6c78202c52196d2c162 upstream.

[WHY]
In cases where a clock table is malformed such that fclk entries have
frequencies but not voltages listed, we don't catch the error and set
clocks to 0 instead of using hardcoded values as we should.

[HOW]
Add check for clock tables fclk entry's voltage as well
