Sent: Thursday, July 13, 2023 3:58 PM To: amd-gfx@xxxxxxxxxxxxxxxxxxxxx <amd-gfx@xxxxxxxxxxxxxxxxxxxxx> Cc: Wentland, Harry <Harry.Wentland@xxxxxxx> Subject: [PATCH v2] drm/amd/display: Use root connector's colorspace property for MST After driver init we shouldn't create new properties. Doing so
will lead to a warning storm from __drm_mode_object_add. We don't really need to create the property for MST connectors. Re-using the mst_root connector's property is fine. v2: Add curly braces to avoid possibly 'else' confusion Signed-off-by: Harry Wentland <harry.wentland@xxxxxxx> --- drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) 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 28f8ac6007fb..f6dab6226b29 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -7357,8 +7357,14 @@ void amdgpu_dm_connector_init_helper(struct amdgpu_display_manager *dm, drm_connector_attach_colorspace_property(&aconnector->base); } else if (connector_type == DRM_MODE_CONNECTOR_DisplayPort || connector_type == DRM_MODE_CONNECTOR_eDP) { - if (!drm_mode_create_dp_colorspace_property(&aconnector->base, supported_colorspaces)) - drm_connector_attach_colorspace_property(&aconnector->base); + if (!aconnector->mst_root) { + if (!drm_mode_create_dp_colorspace_property(&aconnector->base, supported_colorspaces)) + drm_connector_attach_colorspace_property(&aconnector->base); + } else { /* use root connector's property */ + if (aconnector->mst_root->base.colorspace_property) + drm_connector_attach_colorspace_property(&aconnector->mst_root->base); + } + } if (connector_type == DRM_MODE_CONNECTOR_HDMIA || -- 2.41.0 |
