The Linux 7.1 kernel is gaining a new DRM 'BACKGROUND_COLOR' property for CRTCs, allowing display controllers to show non-black background colors for pixels not covered by any plane or exposed through transparent regions. The primary motivation is reduced memory bandwidth in environments with solid background colors. The property is initially wired up for the Rockchip display driver and the generic VKMS driver. Other drm-misc-next changes this week include improved debugging for the AMDXDNA Ryzen AI driver, engine reset on TDR errors for the Intel NPU IVPU driver, and better error handling for the Raspberry Pi V3D driver.
