From 1cb69b43550b6c20819decba870db34175677b2a Mon Sep 17 00:00:00 2001 From: Dillon Varone Date: Tue, 1 Nov 2022 16:38:20 -0400 Subject: [PATCH] drm/amd/display: Program pipes for ODM when removing planes [WHY?] Software state expects pipes to be configured for ODM, but due to the transition occurring on a plane disable, the ODM enablement code is not run. [HOW?] Update ODM when removing a plane, and dynamic ODM is active. Also acquire pipe lock when removing a plane.
