Class CpuFrequencyMetricsReporter

java.lang.Object

com.facebook.battery.reporter.cpu.CpuFrequencyMetricsReporter

All Implemented Interfaces:

SystemMetricsReporter<CpuFrequencyMetrics>

public class CpuFrequencyMetricsReporter
extends java.lang.Object
implements SystemMetricsReporter<CpuFrequencyMetrics>

Reports cpu statuses to an event. As a simplification, the CpuFrequencyMetricsCollector collects and maintains information about each cpu instead of the cluster of cpus it belongs to because of varying levels of topology file access observed across different phones.

The reporter groups equal frequency values together into a cpumask (similar to that reported by the topology sysfs files) mapped to the corresponding frequency.
