From c7f1daa1d62b373cdcf6817e9edb94c121c9ebd9 Mon Sep 17 00:00:00 2001 From: Nicholas Kazlauskas Date: Wed, 8 Jul 2020 16:30:26 -0400 Subject: [PATCH] drm/amd/display: Fix CSC remap matrix not being applied on dcn30 [Why] DCN3 has two gamut remap matrices. When using CSC adjustment the CM remap is set to bypass and MPCC remap is used. However to bypass CM some state in the context is modified and not restored correctly resulting in subsequent calls to disable MPCC remap as well. [How] Fix logic for save/restore of remap enable flag when programming MPCC remap matrix.
