[igt-dev] [RFC PATCH i-g-t 0/2] tests/kms_ccs: CCS Clear Color Test

[Mika Kahola]

This is a RFC patch that proposes to test CCS clear color
capability. This is actually a third edition of the clear color
tests. The first two required tweaking and all received comments
have been helpful. Therefore, any comments/proposals to improve
the test are warmly welcomed

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.
