Abstract:
A computing device may comprise a first processor and a secondary processor. The first processor may initiate a power management process transitioning the first processor from a first state to a second state and, upon reaching a predetermined step in the power management process, notify the secondary processor of the power management process. The secondary processor may initiate, in response to the notifying, a parallel power management process transitioning the secondary processor from an equivalent first state to an equivalent second state.
