[PATCH i-g-t v4 0/2] tests/i915/perf: Exercise barrier race

[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.

Note: Subtest version 3, not yet submitted to upstream.

v4: see subtest patch
v3: move the subtest out of tests/i915/perf.c, add it to
    tests/i915/gem_ctx_exec.c,
  - don't touch lib/i915/perf.c (Umesh, Ashutosh), duplicate reused code
    from tests/i915/perf.c in tests/i915/gem_ctx_exec.c.
v2: limit the scope of submission to barrier-race,
  - see also changelog in the patch itself.
