Would be nice to enable this if it is supported, even if the hw can't do HDR. This is also useful for non-HDR to get effectively 11 bpc precision from the fb to the display outputs for more precise color reproduction. thanks, -mario _______________________________________________ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx
