Abstract
Systems and methods of managing transactions provide for receiving a first flush command at a first I/O hub, wherein the first flush command is dedicated to non-posted transactions. One embodiment further provides for halting an inbound ordering queue of the first I/O hub with regard to non-posted transactions in response to the first flush command and flushing a non-posted transaction from an outgoing buffer of the first I/O hub to a second I/O hub while the inbound ordering queue is halted with regard to non-posted transactions.
