class CpuStressor
Defined at line 90 of file ../../src/zircon/bin/hwstress/cpu_stressor.h
A CpuStressor performs the given workload on multiple CPUs in the system,
coordinating the creation and destruction of threads.

void ~CpuStressor ()Defined at line 92 of file ../../src/zircon/bin/hwstress/cpu_stressor.cc
void CpuStressor (std::vector<uint32_t> cores_to_test, std::function<void (WorkIndicator)> workload, double utilization, ProfileManager * manager)Create a CPU stressor that runs the given workload function.
|workload| should loop until the given StopIndicator has its
|ShouldStop| method return true.
|utilization| should be a value between 0.0 and 1.0 indicating the
fraction of CPU that should be used in the long run.

void CpuStressor (std::vector<uint32_t> cores_to_test, std::function<void ()> looping_workload, double utilization, ProfileManager * manager)Create a CPU stressor that calls the given workload function in
a tight loop.
The given workload should perform a small chunk of work (roughly in
the range of 100 microseconds to 10 milliseconds) that exercises the
CPU.
|utilization| should be a value between 0.0 and 1.0 indicating the
fraction of CPU that should be used in the long run.

void Start ()Start the workload. Must not already be started.
Defined at line 94 of file ../../src/zircon/bin/hwstress/cpu_stressor.cc
void Stop ()Stop the workload, blocking until all threads have completed.
