From 88f8113ab118ed0e187331324d6b60c694b2e0e2 Mon Sep 17 00:00:00 2001 From: Melissa Wen Date: Fri, 7 Aug 2026 13:56:21 +0200 Subject: [PATCH] drm/amd/display: use plane color_mgmt_changed to track colorop changes This is a resubmission of commit d79716401a95 ("drm/amd/display: use plane color_mgmt_changed to track colorop changes") whose change was reverted by commit 0461ba9a7994 ("Merge tag 'amd-drm-next-7.3-2026-07-02' of https://gitlab.freedesktop.org/agd5f/linux into drm-next") during a merge conflict resolution. Original commit message: ``` Ensure the driver tracks changes in any colorop property of a plane color pipeline by using the same mechanism of CRTC color management and update plane color blocks when any colorop property changes. It fixes an issue observed on gamescope settings for night mode which is done via shaper/3D-LUT updates. ``` Fixes: 0461ba9a7994 ("Merge tag 'amd-drm-next-7.3-2026-07-02' of https://gitlab.freedesktop.org/agd5f/linux into drm-next") Acked-by: Alex Deucher Signed-off-by: Melissa Wen Link: https://patch.msgid.link/20260807115712.22423-1-mwen@igalia.com --- drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index ec483276d753..2fe934036e36 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -3879,7 +3879,7 @@ static void amdgpu_dm_commit_planes(struct drm_atomic_commit *state, continue; bundle->surface_updates[planes_count].surface = dc_plane; - if (new_pcrtc_state->color_mgmt_changed) { + if (new_pcrtc_state->color_mgmt_changed || new_plane_state->color_mgmt_changed) { bundle->surface_updates[planes_count].gamma = &dc_plane->gamma_correction; bundle->surface_updates[planes_count].in_transfer_func = &dc_plane->in_transfer_func; bundle->surface_updates[planes_count].gamut_remap_matrix = &dc_plane->gamut_remap_matrix; @@ -5698,6 +5698,10 @@ static bool should_reset_plane(struct drm_atomic_commit *state, if (new_crtc_state->color_mgmt_changed) return true; + /* Plane color pipeline or its colorop changes. */ + if (new_plane_state->color_mgmt_changed) + return true; + /* * On zpos change, planes need to be reordered by removing and re-adding * them one by one to the dc state, in order of descending zpos.
