[igt-dev] [PATCH i-g-t 2/5] igt/prime_vgem: Skip flip if no display

[Chris Wilson]

We try flipping a vgem surface onto a  i915 scanout. However, if there
is no display we want to disable the kms interface, including the addfb
ioctl. On such systems the call to kms_addfb will naturally fail and the
test cannot be run.
