P-State
CPU P-states represent voltage-frequency control states defined as performance states in the industry standard Advanced Configuration and Power Interface (ACPI) specification (see http://www.acpi.info for more details).
In voltage-frequency control, the voltage and clocks that drive circuits are increased or decreased in response to a workload. The operating system requests specific P-states based on the current workload. The processor may accept or reject the request and set the P-state based on its own state.
P-states columns represent the processor’s supported frequencies and the time spent in each frequency during the collection period.
This metric is collected as part of energy analysis. Collecting energy analysis data with Intel® SoC Watch is available for target Android*, Windows*, or Linux* devices. Import and viewing of the Intel SoC Watch results is supported with any version of the VTune Profiler.
