From 4641169a8c95d9efc35d2d3c55c3948f3b375ff9 Mon Sep 17 00:00:00 2001 From: Fangzhi Zuo Date: Wed, 4 Sep 2024 16:56:45 -0400 Subject: [PATCH] drm/amd/display: Fix incorrect DSC recompute trigger A stream without dsc_aux should not be eliminated from the dsc determination. Whether it needs a dsc recompute depends on whether its mode has changed or not. Eliminating such a no-dsc stream from the dsc determination policy will end up with inconsistencies in the new dc_state when compared to the current dc_state, triggering a dsc recompute that should not have happened.
