[igt-dev] [v7 i-g-t 2/3] tests/kms_color: Add support for Deep-Color
Bhanuprakash Modem
bhanuprakash.modem at intel.com
Wed Mar 16 11:15:02 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"
V4:
* Set max_bpc prop to default before exiting the subtest
* Minor cleanups
