drm/amd/display: fix IPX enablement

2024-03-27T12:57:11+00:00

We need to re-enable idle power optimizations after entering PSR. Since,
we get kicked out of idle power optimizations before entering PSR
(entering PSR requires us to write to DCN registers, which isn't allowed
while we are in IPS).

Revert "drm/amd/display: Fix sending VSC (+ colorimetry) packets for DP/eDP displays without PSR"

2024-03-27T12:52:24+00:00

This causes flicker on a bunch of eDP panels. The info_packet code
also caused regressions on other OSes that we haven't' seen on Linux
yet, but that is likely due to the fact that we haven't had a chance
to test those environments on Linux.

We'll need to revisit this.

This reverts commit 202260f64519e591b5cd99626e441b6559f571a3.

drm/amd/display: Add monitor patch for specific eDP

2024-03-20T17:12:58+00:00

[WHY]
Some eDP panels' ext caps don't write initial values. The value of
dpcd_addr (0x317) can be random and the backlight control interface
will be incorrect.

[HOW]
Add new panel patches to remove sink ext caps.

drm/amd/display: Use freesync when `DRM_EDID_FEATURE_CONTINUOUS_FREQ` found

2024-03-20T17:12:56+00:00

The monitor shipped with the Framework 16 supports VRR [1], but it's not
being advertised.

This is because the detailed timing block doesn't contain
`EDID_DETAIL_MONITOR_RANGE` which amdgpu looks for to find min and max
frequencies.  This check however is superfluous for this case because
update_display_info() calls drm_get_monitor_range() to get these ranges
already.

So if the `DRM_EDID_FEATURE_CONTINUOUS_FREQ` EDID feature is found then
turn on freesync without extra checks.

v2: squash in fix from Harry

This reverts commit 11b92df8a2f7f4605ccc764ce6ae4a72760674df.

This conflicts with how compositors want to handle VRR.  Now
that compositors actually handle VRR, we probably don't need
freesync video.
