Power state management of an input/output servicing component of a processor system

A method of regulating power states in a processing system may begin with a processor component reporting a present processor power state to an input-output hub, where the present processor power state corresponds to one of a plurality of different processor power states ranging from an active state...

Zusammenfassung:	A method of regulating power states in a processing system may begin with a processor component reporting a present processor power state to an input-output hub, where the present processor power state corresponds to one of a plurality of different processor power states ranging from an active state to an inactive state. The input-output hub receives data indicative of the present processor power state and, in response to receiving the present processor power state, establishes a lowest allowable hub power state that corresponds to one of a plurality of different hub power states ranging from an active state to an inactive state. The method continues by determining a present hub power state for the input-output hub, wherein depth of the present hub power state is less than or equal to depth of the lowest allowable hub power state.
