Abstract: A method and apparatus to transmit state information through a communication link. In an example embodiment, an endpoint on a communication link receives a state packet in a first format from a first device. The state packet is translated into a second format to generate a translated packet. The translated packet suitable for communicating the state information through the communication link to another endpoint on the communication link.

Abstract: A shopping cart that supports shopping bag dispenser(s) to enable shoppers to package goods as they shop. Shopping bag dispensers may be connected to fixtures that support goods to enable shoppers to obtain shopping bags while shopping.

Abstract: A switching fabric handles transactions using a protocol that directs packets based on path routing information. Components participate in transactions using a protocol that issues packets based on physical location of a destination device over the switching fabric, by establishing a virtual link partner relationship between the components.

Abstract: A method and apparatus for assigning data traffic classes to virtual channels in communications networks is generally described. In accordance with one embodiment of the invention, a node receiving a data packet including content to initialize a virtual channel on a point-to-point communication link to another node, initializing the virtual channel, based on the content, and mapping a data traffic class to the initialized virtual channel.

Abstract: A method and an apparatus to configure a multi-port device are disclosed. The method includes defining a first set of pointers, one for each port of the multi-port device, and storing the first set of pointers in one or more capability structures of the multi-port device.

Abstract: A method and apparatus for signaling virtual channel support in communication networks. A node receives a data packet from another node to examine whether the other node commonly supports one or more virtual channels of a given type on a point-to-point communication link between the nodes, and the node signaling common support for one or more virtual channels of a given type, based on the content in the received data packet that indicates whether the other node transmitting the data packet has adequate queue resources to support one or more virtual channels of a given type, and based on whether the node has adequate queue resources to support the one or more virtual channels of a given type.

Abstract: 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.

Abstract: 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.

Abstract: Briefly, system and method for message-based power management which may be used, for example, in computer systems and communications networks. Embodiments of the present invention may include, for example, a device connected to a power management controller (PMC); the device and/or the PMC may send, receive, and/or process power management event (PME) messages. Embodiments of the present invention may operate using links in communicative and/or non-communicative modes. Embodiments of the present invention may include a switch, to send/receive, process, create, re-format and/or route one or more PME message on behalf of various devices, for example, a Peripheral Component Interconnect (PCI) device.

Abstract: An amount of data to be pre-fetched during read operations is adaptively modified based upon the experience of previous reads. If previous reads were terminated before all the data desired was obtained, subsequent read amounts may be increased. The initial amount of pre-fetched data may be pre-set or modified dynamically.

Abstract: A distributed power management system for a bus architecture or similar communications network. The system supports multiple low power states and defines entry and exit procedures for maximizing energy savings and communication speed.

Abstract: Disclosed are a system and method of configuring processing resources for communication with one or more devices coupled to a data bus through a bridge. Resources at a processing system may be configured to communicate with the bridge as a transparent bridge or a non-transparent bridge depending on how the processing system may be implemented in a processing platform.

Abstract: Disclosed are a system and method for forwarding data packets from ingress ports to egress ports on a switch. A forwarding circuit may commence forwarding data packets from an ingress port through a switch fabric to a transmit queue of an egress port prior to completion of a checksum operation.

Abstract: A way is disclosed of establishing at system reset of both physical operating speed limitations imposed on a secondary bus by a circuit layout as well as the speed capabilities of agents attached to the bus, so that a secondary bus clock speed may be set at the highest permissible speed existing at the time of system reset.

Abstract: A bridge has a first interface that receives a request through a first bus from a requestor that request to read data, and a second interface that forwards the request through a second bus to a device that connects to a memory. The device obtains the requested data from the memory and forwards to the bridge, which then sends the data to the requestor in an appropriate manner.

Abstract: A requesting device and a completer device are coupled via a high-speed serial interface within a computer system. The requesting device transmits a packet for a request transaction to a completer device. The completer device checks for error conditions in the course of servicing the request. If an error condition is found then the completer device transmits a completion packet with a completion status of something other than successful. The completion packet includes a completer identification field. The requesting device records the completer identification value and indicates in a register that a completion packet has been received with a non-successful completion status.

Abstract: Disclosed are a system and method of transmitting data in a processing platform. A switch may comprise an upstream port coupled to a root device to communicate with a processing system. The switch may also comprise a plurality of downstream ports where each downstream port is adapted to be coupled to a device. Data may be transmitted between downstream ports based upon routing information for transmitting data from the upstream port to each of the downstream ports.
