FWIW, I would absolutely *love* to be able to exercise Weston's
DRM-backend in Gitlab CI with anything, even just vkms, at least in
Weston's test suite to test Weston against KMS in general. Once that is
up, kernel people could replicate from that to their own CI for testing
drivers against known userspace.

I think it would be an awesome long term plan, whether uAPI specs
appear or not. Long term, because I have no idea who could work on it
when. In theory, all I would be waiting for is for vkms to be just
featureful enough and to figure out a way how to get that running
inside Gitlab CI.


Thanks,
