摘要： An apparatus and method is provided for allowing I/O devices to be shared and/or partitioned among a plurality of processing complexes within the load/store fabric of each of the processing complexes without requiring modification to the operating system or driver software of the processing complexes. The apparatus and method includes a switch for selectively coupling each of the processing complexes to one or more shared I/O devices. The apparatus and method further includes placing information within packets transmitted between the switch and the I/O devices to identify which of the processing complexes the packets are associated with. The invention further includes an apparatus and method within the shared I/O devices to allow the shared I/O devices to service each of the processing complexes independently.

摘要： An apparatus and method are provided that enable I/O devices to be shared among multiple operating system domains. The apparatus has a first plurality of I/O ports, a second I/O port, and core logic. The first plurality of I/O ports is coupled to a plurality of operating system domains (OSDs) through a load-store fabric, each routing transactions between the plurality of OSDs and the switching apparatus. The second I/O port is coupled to a first shared input/output endpoint. The first shared input/output endpoint requests/completes the transactions for each of the plurality of OSDs. The core logic is coupled to the first plurality of I/O ports and the second I/O port. The core logic routes the transactions between the first plurality of I/O ports and the second I/O port. The core logic designates a corresponding one of the plurality of OSDs according to a variant of a protocol, where the protocol provides for routing of the transactions only for a single OSD.

摘要： A processor includes controller circuitry operative to control the storage of a plurality of separate linked list data structures for protocol data units received by the processor. The linked list data structures are stored in memory circuitry associated with the processor, and the memory circuitry is arranged in a plurality of banks. The plurality of banks are configured to store respective ones of the plurality of separate linked list data structures, such that each of the plurality of banks stores a corresponding one of the plurality of separate linked list data structures. The linked list data structures are accessed in an alternating manner that reduces the likelihood of access conflicts between the banks. The processor may be configured as a network processor integrated circuit to provide an interface between a network and a switch fabric in a router or switch.

摘要： A processor includes controller circuitry configurable to determine for a given packet or other protocol data unit (PDU) received by the processor whether the given PDU is a single-cell PDU. If the given PDU is a single-cell PDU, information characterizing the given PDU is stored in first memory circuitry internal to the processor, without utilizing a linked list data structure. If the given PDU is not a single-cell PDU, information characterizing the PDU is stored in second memory circuitry external to the processor, utilizing a linked list data structure. The processor may be configured as a network processor integrated circuit to provide an interface between a network and a switch fabric in a router or switch.

摘要： An apparatus and method are provided that enable I/O devices to be shared among multiple operating system domains. The apparatus includes a first plurality of I/O ports, a second I/O port, and a plurality of port initialization logic elements. The first plurality of I/O ports is coupled to a plurality of operating system domains through a load-store fabric. Each of the first plurality of I/O ports routes transactions between the plurality of operating system domains and the switching apparatus. The second I/O port is coupled to a first shared input/output endpoint. The first shared input/output endpoint is configured to request/complete the transactions for each of the plurality of operating system domains. One of the plurality of port initialization logic elements is coupled to the second I/O port and remaining ones of the plurality of port initialization logic elements are each coupled to a corresponding one of the first plurality of I/O ports. The plurality of port initialization logic elements is configured to initialize corresponding links between each of the plurality of operating system domains and the switching apparatus, and between the first shared input/output endpoint and the switching apparatus, to support the transactions, where each of the plurality of port initialization logic elements automatically configures a corresponding polarity for each of the first plurality of I/O ports and the second I/O port, and where the corresponding polarity is in a default polarity prior to being configured.
