[Intel-gfx] [PATCH 4/4] Use YCbCr420 as fallback when RGB fails

2021-05-03 Thread Werner Sembach
When encoder validation of a display mode fails, retry with less bandwidth heavy YCbCr420 color mode, if available. This enables some HDMI 1.4 setups to support 4k60Hz output, which previously failed silently. AMDGPU had nearly the exact same issue. This problem description is therefore copied fro
