[igt-dev] [PATCH i-g-t v3 0/1] tests/i915/perf: Add stress / race exercises

[Janusz Krzysztofik]

Users reported oopses on list corruptions when using i915 perf with a
number of concurrently running graphics applications.  That indicates we
are currently missing some important tests for such scenarios.  Cover
that gap.

v3: locate the new subtest in a new tests, intedned for exercising
    intentionally racy barrier tasks list processing,
  - fixes and optimizations (see the patch changelog for details).
v2: drop open-race subtest for now, not capable of triggering the user
    reported bug, but triggering other bugs which I can't see any fixes
    for queued yet,
  - move the other new subtest out of tests/i915/perf.c (Ashutosh).
