[igt-dev] [RFC PATCH i-g-t v2 0/2] tests/kms_ccs: CCS Clear Color test

[Mika Kahola <mika.kahola@intel.com>]

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.

Logically it may be an odd plae to define color clear function in
intel_batchbuffer.c but I decided to do so as we have rendercopy and
veboxcopy functions defined there as well.

v2: Modify _gen9_render_copyfunc to support fast clear (Matt)
    Enable fast clear bit on 3D sequence (Matt)
    Add helper function to figure out clear color modifier (Matt)

Mika Kahola (2):
  tests/kms_ccs: Add debug information on format modifier
