ABSTRACT:
In one embodiment, the present invention includes a method for receiving an information packet in a first port from an interconnect while an agent associated with the first port is in an idle low power state, transmitting a first signal from the first port along the interconnect to request re-transmission of the information packet, and sending a second signal from the first port to the agent to cause the agent to enter a fully active power state. Other embodiments are described and claimed.
