Satyajit Roy 8cfd9e22eb drm/amd/display: Rebuild InfoFrames on output color space changes ... resource_build_info_frame() derives colorimetry and RGB quantization from stream->output_color_space. A Broadcast RGB-only atomic commit updates that field and reprograms the output CSC, but none of the InfoFrame update predicates include output_color_space. The sink can therefore retain the previous AVI InfoFrame range while the source starts transmitting a different pixel range. Treat an output color space change as an InfoFrame change in update classification and in both stream programming paths. Hardware testing on an HDMI 2.1 television confirmed that its automatic black-level selection follows Full to Limited and Limited to Full transitions in SDR, HDR, and HDR with VRR active, without a modeset or visible link blank.
