System and method for managing P-states and C-states of a system

摘要

A current value of a load indicator of a system is determined, by an application entity, based on one or more of a central processor unit utilization measure of the system, a memory utilization measure of the system, a system-internal resources utilization measure, an input/output utilization measure of the system, and a secondary storage utilization measure of the system, wherein the system is associated with a plurality of P-states and a plurality of C-states. An operating mode of the system is determined, by the application entity, based on the current value of the load indicator, wherein the operating mode comprises a P-state selected from the plurality of P-states and a C-state selected from the plurality of C-states. The system is operated in accordance with the operating mode. A predictive load map associating respective time periods and respective operating modes may be generated and adaptively adjusted.

1. A method of operating a data processing system, wherein the data processing system is associated with a plurality of P-states and a plurality of C-states, comprising:
determining a current value of a load indicator of the system based on a plurality of measures, each measure weighted based on its respective system limit for the data processing system, the plurality of measures including a central processor unit utilization measure of the system, a memory utilization measure of the system, a system-internal resources utilization measure, an input/output utilization measure of the system, and a secondary storage utilization measure of the system; determining an operating mode of the system based on the current value of the load indicator, wherein the operating mode comprises a P-state selected from the plurality of P-states and a C-state selected from the plurality of C-states; and operating the system in accordance with the operating mode.
