linux.git/drivers/gpu/drm/amd/display/dc/mpc/dcn60, branch master Linux kernel source tree drm/amd/display: Migrate color manager HW and fix MCM blend LUT issues 2026-08-06T16:44:26+00:00 Rafal Ostrowski rafal.ostrowski@amd.com 2026-07-28T14:39:37+00:00 41951483258971e4f312275cddcdd2dad9fd48f5 Combine two related color manager improvements: 1. Migrate MCM/RMCM, shaper and 3DLUT HW programming to dc_plane_cm - Continue convergence with upstream Color Manager refactor - Migrate MCM/RMCM, shaper and 3DLUT programming for dcn401+ to dc_plane_cm - Unify MCM programming across both legacy and 3DLUT DMA paths - Add 3DLUT DMA broadcast support for multi-pipe planes 2. Reprogram MCM blend LUT on blend_enable falling edge - Fix issue where SDR desktop remained desaturated after video playback - Detect blend_enable falling edge (1->0) in surface update detection - Force MCM LUT reprogramming on blend state change Reviewed-by: Dillon Varone <dillon.varone@amd.com> Signed-off-by: Rafal Ostrowski <rafal.ostrowski@amd.com> Signed-off-by: Roman Li <roman.li@amd.com> Tested-by: Dan Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
