[PATCH i-g-t] i915/gem_ringfill: Do a basic pass over all engines simultaneously

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

 



Change the basic pre-mergetest to do a single pass over all engines
simultaneously. This should take no longer than checking a single
engine, while providing just the right amount of stress regardless of
machine size.

v2: Move around the quiescence and requires to avoid calling them from
the children.
