Hi, This series is kind of an optimization we can make on Gen7.5 for dealing with the perf stream in the case where we measure workloads at boundaries of the command stream (much like what i965 INTEL_performance_query does in Mesa). Along the way to implement this, quite a few cleanups manifested themselves. igt@perf@missing-sample-flags is expected to fail with this series. An igt patch will fix this.
