Abstract
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.
