Public Methods
bool MultiCpuMergeTest ()Verifies that the aggregated stats are the average of per-CPU stats, weighted by `active` time.
Defined at line 74 of file ../../zircon/kernel/lib/stall/tests/stall_test.cc
bool TimersDoNotRestartTest ()Verifies that global stats keep increasing by simulating a system with one CPU, and verifying
that the global stats correspond to the running total of values it reports.
Defined at line 101 of file ../../zircon/kernel/lib/stall/tests/stall_test.cc
bool IdleSystemTest ()Verifies that, if the overall `active` time of all CPUs is zero (i.e. if the denominator of the
weighted average is zero), the resulting stall timers are simply left unchanged.
Defined at line 133 of file ../../zircon/kernel/lib/stall/tests/stall_test.cc
template <ObserverThresholdTestSelector test_variant>bool ObserverThresholdTest ()Verifies that the StallObserver receives data from the StallAggregator and that it applies the
threshold correctly. Depending on the template argument, this test will exercise either the
"some" or "full" counter.

bool ObserversManyTest ()Verifies that all registered observers receive the updates.
