ABSTRACT:
A distributed power management technique allows controlling power states of devices separated from a power management controller, such as a processor, by an interconnect. The power management controller inserts power state information into an interconnect transaction. An interconnect connected device then extracts the power state information and modifies the power state of the device responsive to the power state information. The power state information can be extracted by a processor that then controls the power state of another device responsive to the power state information.
