Abstract: Dynamic adjustment of power modes including: detecting an application identified in an application power policy; limiting an application power consumption of a computing component based on the application power policy; monitoring power consumption of a computing component; and selecting a power mode based on the monitored power consumption of the computing component and a power consumption threshold for each of a plurality of power modes.

Abstract: Power shifting based on bottleneck prediction, including: determining a first plurality of performance metrics for an accelerated processing unit (APU) and a second plurality of performance metrics for a graphics processing unit (GPU); providing the first plurality of performance metrics and the second plurality of performance metrics as an input to a model configured to identify one or more bottlenecks in the APU or the GPU; determining, based on an output of the model, a power distribution between the APU and the GPU; and applying the power distribution.

Abstract: Techniques are described for adaptive device power management. The device interface application of a hardware computing unit detects a launch of an application by the operating system (OS) to be executed on the hardware computing unit, in an implementation. The device interface application identifies the launched application and determines whether a hardware profile exists that is associated with the application. The hardware profile includes one or more hardware parameters that yield the optimal performance for power consumption by the hardware computing unit when executing the launched application. Based on determining that the hardware profile exists, the power policy of the OS is updated for the launched application, and thereby, the driver updates the power state(s) of the hardware computing unit based on the new power policy.
