drm/amd/display: Set vsc pack revision when DPCD revision is >= 1.2

2018-05-30T06:17:42+00:00

[ Upstream commit 3b94a4007dcfd4ac5780cd3d8a2d99979c966073 ] Brightness couldn't change when booting up in DC mode. It was because "psr_enabled" flag was not set to true before setting vsc packet revision, causing packet rev setup was skipped. Now instead of checking the psr flag, it checks if the DPCD_REV >= 1.2 and set the vsc packet revision.

drm/amd/display: Disallow enabling CRTC without primary plane with FB

2018-05-01T19:47:29+00:00

commit f2877656809386d7bc62c2b1c1b4e58404c486d4 upstream. The below commit "drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2" introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, it now preserves it. Since DC is currently not equipped to handle this we need to fail such a commit, otherwise we might see a corrupted screen. This is based on Shirish's previous approach but avoids adding all planes to the new atomic state which leads to a full update in DC for any commit, and is not what we intend. Theoretically DM should be able to deal with states with fully populated planes, even for simple updates, such as cursor updates. This should still be addressed in the future.

drm/amd/display: Don't read EDID in atomic_check

2018-05-01T19:47:29+00:00

commit c7b8de00384be49dc1617a838b0ce89a0235f319 upstream. We shouldn't attempt to read EDID in atomic_check. We really shouldn't even be modifying the connector object, or any other non-state object, but this is a start at least. Moving EDID cleanup to dm_dp_mst_connector_destroy from dm_dp_destroy_mst_connector to ensure the EDID is still available for headless mode.
