    摘要: A caching input/output hub includes a host interface to connect with a host. At least one input/output interface is provided to connect with an input/output device. A write cache manages memory writes initiated by the input/output device. At least one read cache, separate from the write cache, provides a low-latency copy of data that is most likely to be used. The at least one read cache is in communication with the write cache. A cache directory is also provided to track cache lines in the write cache and the at least one read cache. The cache directory is in communication with the write cache and the at least one read cache.

    摘要: 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.
