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 link training logic. 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 is configured to route 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. The link training logic is coupled to the second I/O port. The link training logic initializes a link between the second I/O port and the first shared input/output endpoint to support the transactions corresponding to the each of the plurality of operating system domains. The link is initialized in a manner that is transparent to the plurality of operating system domains.

摘要： A method of operating a bus interconnect coupled to bus masters and bus slaves is provided. The method includes receiving a request from a bus master to perform a bus transaction associated with a transaction ID with a bus slave of the plurality of bus slaves, the bus transaction being a first type of bus transaction. The method further includes performing the transaction if a resource allocation parameter allocated to the bus master meets a first threshold. The method further includes if the resource allocation parameter does not meet the first threshold, performing the data transaction only if the transaction meets a condition of a set of at least one condition, wherein a condition of the set of at least one condition includes that the transaction ID of the transaction is not a transaction ID of any outstanding bus transaction of the first type requested by the bus master.

摘要： A method enabling I/O devices to be shared among multiple operating system domains, including first communicating with each of the operating system domains according to a protocol that provides exclusively for a single system domain ithin the load-store fabric; and second communicating with the shared I/O endpoint according to a variant of the protocol to enable the shared I/O endpoint to associate a prescribed operation with a corresponding one of the independent operating system domains. The second communicating includes encapsulating an OS domain header within a transaction layer packet that otherwise comports with the protocol, wherein the value of the OS domain header designates the corresponding one of the operating system domains; and via core logic within a swithching apparatus, mapping the independent operating system domains to the shared I/O endpoint.
