Subject: [RFC PATCH 0/1] drm: selftest: Convert to KUnit

Hi,

This RFC is a preview of the progress we made in the KUnit hackathon[0].
This patch, made by Maíra and Arthur, converts the damage helper test
from the original DRM selftest framework to use the KUnit framework.

[0] https://groups.google.com/g/kunit-dev/c/YqFR1q2uZvk/m/IbvItSfHBAAJ

The IGT part of this work can be found here:
https://gitlab.freedesktop.org/isinyaaa/igt-gpu-tools/-/tree/introduce-kunit

We also have patches in progress converting the following tests:
framebuffer, cmdline_parser, dp_mst_helper, rect and dma-buf. As soon as
we sort out if this is the right way to proceed in both kernel and IGT
side, the hackathon participants will submit them.

Below, a dmesg output followed by the IGT output of the damage helper
test.

Thanks!
