Claim Text:
1. An integrated circuit comprising: a sideband On-die System Fabric (OSF) to couple a first agent and a second agent, wherein the sideband OSF is to allow the first agent and the second agent to communicate out-of-band information via one or more routers; and power management logic to initiate a request to reset a segment of a plurality of segments of the sideband OSF, wherein each segment of the plurality of segments is to be located in a separate power domain, wherein each segment of the plurality of segments is to include at least one of the one or more routers, wherein the power management logic is to cause the segment to reset in response to an acknowledgement from one or more agents in the segment of the plurality of segments that the one or more agents have handled all in-progress posted messages, wherein the separate power domain is to comprise a chipset suspend power domain, wherein the chipset suspend power domain is to comprise the power management logic, wherein the one or more agents are to block new posted and non-posted messages in response to a broadcast message from the power management logic, wherein the one or more agents are to finish in-progress posted-posted handshake messages in response to a message from the power management logic.
