> map-fixed-invalidate* subtests utilize gem_set_tiling() which may fail,
> e.g. on hardware with no mappable aperture, due to missing fences.
> Skip those subtests if fences are not available.
>
> Moreover, those subtests use GEM_MMAP_GTT IOCTL which has been replaced
> by GEM_MMAP_OFFSET that supports other mapping types, not only GTT.
> Use the new IOCTL and dynamically examine all MMAP_OFFSET types
> supported by hardware.

> v2: Examine all supported MMAP_OFFSET types, not only the first one
> that works,
> - add subtest description.
> v3: Refresh on top of commit 384e7ecb7464 ("lib/i915: Restrict mmap
> types to GTT if no MMAP_OFFSET support").
