Abstract
Described herein in various embodiments are techniques to better coordinate long wakeup events on a network processor that are due to radio or network activity with the long wakeups that are due to requests from an application processor. In one embodiment, power management logic can receive wake requests from system processes upon notice that one or more application processors are transitioning into a low power state. The power management logic can coalesce the wake requests based on a supplied margin and determine a wake timeframe in which the application processor may be opportunistically woken from the low power state. The power management logic can provide the wake timeframe for the application processor to a network processor in the system. The network processor can opportunistically cause an early wake of the application processor during the wake timeframe.
