[igt-dev] [PATCH i-g-t v3 0/3] validate color tests using chamelium.

[Kunal Joshi]

For gen11+ platforms, there are frequent crc mismatch issues observed
in color tests. This is happening due to hardware limitation
(pipe rounding). One of the solutions to fix this is by rewriting
color tests and making them compatible with chamelium.

In this patch series, color tests are modified to have frame dump
comparison instead of crc comparison using chamelium hooks. This
will be useful even for future platforms. Also, with this approach
we could enable limited-range subtest which was commented in kms_color
because of crc mismatch.

Kunal Joshi (3):
  lib/igt_chamelium Added chamelium_frame_match_or_dump which returns
    bool that the captured frame matches
  lib/igt_color Moved kms_color functions to lib/igt_color to git avoid
    code duplication
  tests/kms_color_chamelium: add subtests to validate color
