[igt-dev] [PATCH i-g-t v5 4/4] tests/kms_color: MPO + pipe color test for ctm

Ananya Sharma ananya.sharma at intel.com
Mon Mar 6 19:10:50 UTC 2023


Adding multiple planes with two different formats i.e. RGB and NV12 in
pipe color test for ctm. This will increase the YUV coverage in color
management.
