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. > > thanks, > > greg k-h Best, Sumit [1]: https://cgit.freedesktop.org/drm/igt-gpu-tools [2]: https://intel-gfx-ci.01.org
