From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

Some reworks to hopefully improve the reliability of tests on small core
machines.

Mostly ensuring measured sleep approach is always used in tests which look at
time, and that time spent setting up the test is ignored as much as possible.

Tvrtko Ursulin (3):
  tests/perf_pmu: Tighten busy measurement
  tests/perf_pmu: More busy measurement tightening
  tests/perf_pmu: Use measured sleep in all time based tests
