[igt-dev] [RFC PATCH 0/7] IGT tests for the KMS Color Pipeline API

This series introduces support for
* drm_colorop DRM objects
* COLOR_PIPELINE plane property

Kernel changes:

libdrm changes:
https://gitlab.freedesktop.org/hwentland/drm/-/merge_requests/1

It also adds a new kms_colorop test case that tests the color pipeline
API. The tests are designed to be easily extensible with a "transform"
and "compare" function pointer for each test. The "transform" function
performs the transformations under test via SW routines. The "compare"
function compares the DRM/KMS result (via a writeback connector) with
the result derived via the SW "transform".

Currently there is only one test for a single sRGB EOTF. I would like
to expand this to a more complex color pipeline, using VKMS.
