Dynamic processor power management

A computing device comprising:

• one or more processors;
• an operating system application interface in an operating system executing on the one or more processors and configured to receive one or more workloads from an application, each of the one or more workloads being associated with completion deadline information and execution metadata representing execution guidance for the workload;
• and
• an operating system power management module in the operating system executing on the one or more processors and configured to:
• generate a processor performance adjustment in the operating system power management module for each of the one or more workloads providing the processor performance adjustment based on the completion deadline information and the execution metadata for each of the one or more workloads,
• communicate each of the one or more received workloads and its corresponding generated processor performance adjustment from the operating system to a processor subsystem, each of the processor performance adjustments instructing the processor subsystem on a processor adjustment to be implemented when executing the associated workload,
• execute each of the one or more received workloads by the processor subsystem based on the processor performance adjustment;
• update a performance model executed by an operating system power management layer in the operating system based on the completion deadline information for each workload, the update being responsive to completion of execution of each workload;
• and
• generate a new processor performance adjustment in the operating system for a new workload using the updated performance model.

One or more tangible processor-readable storage media embodied with instructions for executing on one or more processors and circuits of a computing device a process comprising:

• receiving in an operating system one or more workloads from an application, each of the one or more workloads being associated with completion deadline information and execution metadata representing execution guidance for the workload;
• generating in the operating system a processor performance adjustment for each of the one or more workloads using a performance model providing the processor performance adjustment based on the completion deadline information and the execution metadata for each of the one or more workloads;
• and
• communicating from the operating system each of the one or more received workloads and its corresponding generated processor performance adjustment to a processor subsystem, each of the processor performance adjustments instructing the processor subsystem on a processor adjustment to be implemented when executing the associated workload;
• executing each of the one or more received workloads by the processor subsystem based on the processor performance adjustment;
• updating a performance model executed by an operating system power management layer in the operating system based on the completion deadline information for each workload, the update being responsive to completion of execution of each workload;
• and
• generating a new processor performance adjustment in the operating system for a new workload using the updated performance model.
