[igt-dev] [PATCH i-g-t 2/2] tests/kms_color_chamelium: add subtests to validate color.
Kunal Joshi
kunal1.joshi at intel.com
Tue Jan 14 13:35:04 UTC 2020
To validate color subtests using chamelium, subtests modified
to do frame dump comparison instead of crc comparison.
Tests require chamelium and will validate color features
at pipe level.
