I've created a few patches to test that in gitlab CI. I think the only
thing left now is CI'ing sysroot builds, but I don't know how to do that
myself.

We're in the process of moving i915 tests into a tests/i915/ subfolder. I
think after that we could try to them on some hardware (my long term plan
is to use vkms for that and put it into gitlab CI with qemu). We have
accidentally run igts on amdgpu instead of i915 on KBL-G (and our CI found
at least one bug in one of my refactor series), so stuff works :-)

Coverage is a bit a mixed bag I think, but that's always the case when you
retrofit a testsuite.
