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： A computer system includes compute nodes coupled through a switch to shared or non-shared I/O devices. The switch includes a pool of bridge headers and virtual bridges coupling a root port of a compute node to each of one or more shared or non-shared I/O devices. The switch is configured to associate each of the virtual bridges with a respective one of the fixed pool of bridge headers, receive a packet including data identifying the root port and a shared or non-shared I/O device, and route the packet in response to comparing data in the packet to data in the bridge headers associated with the virtual bridges. The virtual bridges comprise a hierarchy of virtual bridges in which one virtual bridge connects the root port to the remaining virtual bridges of the hierarchy. The switch may change the associations between virtual bridges and bridge headers.

摘要： A network interface controller is provided which is shareable by a plurality of operating system domains within their load-store architecture. The controller includes local resources for each of the plurality of operating system domains which allow them to communicate uniquely with the controller, and global resources which allow the controller to communicate with each of the plurality of operating systems, as well as with a network fabric. A method and apparatus is provided for distinguishing between the local and global resources, for purposes of reset and configuration. Resets received from ones of the plurality of operating system domains are treated as hot-pluggable events, and utilize a reset DLLP packet to the controller. The controller allows the reset DLLP to reset only those local resources which are associated with the operating system transmitting the reset, while preserving the other local resources. Registration logic is provided to allow one of the operating system domains to register as management (or reset) master, for configuration and reset of global resources. Timer logic is provided to insure that if global configuration fails, the management master is unregistered. Status/Messaging logic is provided to notice other operating system domains of the status of global configuration and/or reset.

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.

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 shared network interface controller (NIC) interfaces a plurality of operating system domains as part of the load-store architecture of the operating system domains. A bus interface couples the NIC to a load-store domain bus (such as PCI-Express), using header information to associate data on the bus with an originating operating system domain. Transmit/receive logic connects the NIC to the network. Association logic allows the NIC to designate, and later lookup, which destination MAC address (on the Ethernet side) is associated with which operating system domain. Descriptor register files and Control Status Registers (CSR's) specific to an operating system domain are duplicated and made available for each domain. Several direct memory access (DMA) engines are provided to improve throughput. Packet replication logic, filters (perfect and hash) and VLAN tables are used for looping back packets originating from one operating system domains to another and other operations.
