[igt-dev] [PATCH i-g-t v2 0/2] 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 (2):
  lib/igt_chamelium: added function returning a bool to compare
    framebuffer reference with framedump.
  tests/kms_color_chamelium: add subtests to validate color.

[igt-dev] [PATCH i-g-t v2 1/2] lib/igt_chamelium: added function returning a bool to compare framebuffer reference with framedump.

[Kunal Joshi]

Added chamelium_frame_match_or_dump which returns bool that the captured
frame matches with reference framebuffer.

(v2)
        Removed previously added function chamelium_assert_frame_dump_eq.

[igt-dev] [PATCH i-g-t v2 2/2] tests/kms_color_chamelium: add subtests to validate color.

[Kunal Joshi]

To validate color subtests using chamelium, subtests modified
to do frame dump comparison instead of crc comparison.
Tests require chamelium and will validate color features
at pipe level.

(v2)
        Comparing framedump with framebuffer reference instead of
        comparing two framedump.
