Kunit is fairly easy to grasp if you have some knowledge of other unit
testing frameworks already (pytest, cmocka, etc.)
Another good candidate would be to convert (some ?) selftests to kunit.
I'm not sure the others, but at least test-drm_cmdline_parser should be
fairly easy to convert.

Yes, I didn't set to intermediate due kunit but rather due the format
conversions, since the functions are not easy to read and understand.
And the person writing the unit tests will have to get familiar with
the different formats to verify that conversions are done correctly.

Indeed. Maybe I would add it as a separate entr though, as a follow-up.

All the drm selftest should be good candidates for conversion to kunit.
