[PATCH 5/5] drm/i915: Split ctx timestamp selftest into two

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

 



We use different workarounds for render engine than
for other engines. Split the selftest according to these
types so that we get error rates per workaround.
