Here non-generic part is only those 10 lines of subtests definitions. The rest is common code. I guess, this separate subtest definitions can document the device pairs the test is expected to work + we can blacklist tests which we don't have the hardware for. > The way to do a generic kms testcase is to use DRIVER_ANY (yes some > of the > earlier conversion unfortunately used stuff like DRIVER_INTEL | > DRIVER_AMDGPU).

If I put fd =3D drm_open_driver(DRIVER_ANY) fd2 =3D drm_open_driver(DRIVER_ANY) I get the same device opened two times, do I? >=20 > Imo best to start out by converting prime_vgem.c for this, and adding > for > the i915 specific tests (but _only_ for those) a specific "is this > i915" > check, so we skip those tests.

And prime_vgem use only vgem as an exporter device. Here we can use any device. Sure, some tests would eventually use vgem-specific features, but some could remain more generic.
