Are you referring to the igt-gpu-tools [1]? They also have a CI [2]
that runs these tests, but almost 98% of the tests are i915 specific /
can be only tested on i915 for now. Though I have chatted with Daniel
V a couple of times, and we do see a good scope of collaboration in
getting these tested on ARM as well.

Also, these are drm-specific tests, not testing generic kernel
features per-se. Just my 2 cents here.
