Will be good to mention a comment as well that ICL SDR planes have some issues with BT2020 conversion, hence not enabling it on those planes for ICL. > + supported_csc |= BIT(DRM_COLOR_YCBCR_BT2020); > + > drm_plane_create_color_properties(&plane->base, > - BIT(DRM_COLOR_YCBCR_BT601) | > - BIT(DRM_COLOR_YCBCR_BT709), > + supported_csc, Handle the BT2020 format in glk_plane_color_ctl as well for GLK. > BIT(DRM_COLOR_YCBCR_LIMITED_RANGE) | > BIT(DRM_COLOR_YCBCR_FULL_RANGE), > DRM_COLOR_YCBCR_BT709, > -- > 2.17.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
