[igt-dev] [PATCH i-g-t 2/2] tests/kms_ccs: CCS Clear Color test

Mika Kahola mika.kahola at intel.com
Tue May 19 09:48:03 UTC 2020


This is a RFC patch that proposes to test CCS clear color
capability.

The test paints a solid color on primary fb and a small sprite fb.
These are cleared with fast clear feature. A crc is captured and
compared against the reference.

Clear Color testing is performed with Clear Color DRM format modifier
and with YUV format only.

Any comments/proposals to improve the test are warmly welcomed.
