Abstract
An input/output hub may include an interface unit and one or more communication units. Each communication unit may be configured to receive interrupts or messages from a corresponding endpoint device. A given communication unit may be further configured to synthesize a virtual address from the received message, translate the synthesized virtual address to a real address, and then translate the real address to a physical address. The interface unit may be configured to send an interrupt dependent upon the physical address.
