摘要： A queuing mechanism is described for managing packets between agents of a computer system. The queuing mechanism includes an ordered queue including a plurality of queue registers to store a plurality of packets. The queuing mechanism also includes a bypass queue coupled to the ordered queue, wherein, if a packet at head of the ordered queue is a delayed request and is stalled for lack of flow control credit, then the stalled packet is moved into the bypass queue.

摘要： A method for accessing a configuration space of a device is described. The method includes setting a first field of a packet to a value to specify a destination device, and setting a second field of the packet to a defined value to indicate that the packet is a configuration access packet. The method further includes setting a third field of the configuration access packet to a value to select one of a plurality of configuration apertures of a configuration space of the destination device, and setting a fourth field of the configuration access packet to a value to address a specific memory location within the selected aperture.

摘要： A method and structure(s) for providing a data path between and among nodes and processing elements within an interconnection fabric are described. More specifically, a device comprising a first circuit configured to couple between a first bus and a link is described. The circuit may be configured to operate as a bridge, support PCI configuration cycles, send outgoing information serially through the link in a format different from that of the first bus, and allow a host processor, communicating through the first bus, to selectively address one or more remote devices to which the device is configured to allow access. In some embodiments, the first circuit may support “spoof-proof” data protocols, and the device may operate in multiple modes including root bridge, leaf bridge, and gateway mode. Multiple addressing models may also be used.

摘要： The present invention provides a system and method for encapsulating protocols across a switching fabric network. Packets, which may utilize any underlying protocol, are encapsulated with a route header. This route header contains path routing, traffic and packet size information. A novel path routing scheme is used to route packets across the fabric, where the fabric has a plurality of switches, each having a plurality of ports. Each switch uses only data from within the packet and its own port count to determine the appropriate output port. There is no need to node or address lookup mechanisms in the switches.
