tests/perf_pmu: Tests for i915 PMU API
A bunch of tests for the new i915 PMU feature.
Parts of the code were initialy sketched by Dmitry Rogozhkin.
v2: (Most suggestions by Chris Wilson)
* Add new class/instance based engine list.
* Add gem_has_engine/gem_require_engine to work with class/instance.
* Use the above two throughout the test.
* Shorten tests to 100ms busy batches, seems enough.
* Add queued counter sanity checks.
* Use igt_nsec_elapsed.
* Skip on perf -ENODEV in some tests instead of embedding knowledge locally.
* Fix multi ordering for busy accounting.
* Use new guranteed_usleep when sleep time is asserted on.
* Check for no queued when idle/busy.
* Add queued counter init test.
* Add queued tests.
* Consolidate and increase multiple busy engines tests to most-busy and
all-busy tests.
* Guarantte interrupts by using fences.
* Test RC6 via forcewake.
v3:
* Tweak assert in interrupts subtest.
* Sprinkle of comments.
* Fix multi-client test which got broken in v2.
v4:
* Measured instead of guaranteed sleep.
* Missing sync in no_sema.
* Log busyness before asserts for debug.
* access(2) instead of open(2) to determine if cpu0 is hotpluggable.
* Test frequency reporting via min/max setting instead assuming.
^^ All above suggested by Chris Wilson. ^^
* Drop queued subtests to match i915.
* Use long batches with fences to ensure interrupts.
* Test render node as well.
v5:
* Add to meson build. (Petri Latvala)
* Use 1eN constants. (Chris Wilson)
* Add tests for semaphore and event waiting.
v6:
* Fix interrupts subtest by polling the fence from the "outside".
(Chris Wilson)
v7:
* Assert number of initialized engines matches the expectation.
(Chris Wilson)
* Warn instead of skipping if we couldn't restore the initial
frequency. (Chris Wilson)
* Move all asserts to after the test cleanup (just a tidy).
* More 1eN notation for timeouts.
* Bump the tolerance to 5% since I saw a few noisy runs with
sampling counters.
* Always start the PMU before submitting batches to lower
reliance on i915 doing the delayed engine busy stats disable.
v8:
* Update for upstream engine class enum.
v9:
* Add meson build support.
