A computer-implemented method of controlling power consumption in a multi-processor computing device comprises: determining whether a first processor is operating in a high-power regime or a low-power regime; selecting a first set of control rules that includes a first subset of control rules that apply when the first processor is operating in the high-power regime and a second subset of control rules that apply when the first processor is operating in the low-power regime; determining one or more power settings for the first processor based on the first set of control rules; and causing the first processor to perform one or more operations based on the one or more power settings.

Techniques for controlling computing performance for power-constrained multi-processor computing systems

A method for managing power in a multiple processor computing device includes detecting a first amount of power being used by a first processor of the computing device; determining an amount of extra power available based on the first amount of power and a power budget for the first processor; and transmits a value to a driver associated with a second processor of the computing device, wherein the value indicates the amount of extra power available, wherein the driver adjusts at least one operating parameter of the second processor based on the amount of extra power available.
