[PATCH 4/6] drm/i915/selftest: Cope with not having an RCS engine

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: John Harrison <John.C.Harrison@xxxxxxxxx>

It is no longer guaranteed that there will always be an RCS engine.
So, use the helper function for finding the first available engine that
can be used for general purpose selftets.
