Abstract:
Power supply to system resources is managed by implementing a hardware hook. System resources that should be reconfigured for an application workload are identified. A present power profile in a non-volatile memory is then updated. The present power profile is updated according to the application workload. During a system restart, the present power profile is retrieved from the non-volatile memory. Power is applied to system resources through the hardware hook based on the present power profile.
