[igt-dev] [v4 i-g-t 2/3] tests/kms_color: Add support for Deep-Color

Bhanuprakash Modem bhanuprakash.modem at intel.com
Thu Feb 17 15:54:57 UTC 2022


Add new subtests to validate deep color.

V2:
* i915 needs atleast gen 11 to support deep-color
* Add connector name to dynamic subtest
V3:
* Fix the usage of "output"
