ABSTRACT:
A mechanism that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to perform I/O transactions using the PCI host bus, device, and function numbers to validate that an I/O transaction originated from the proper host is provided. Additionally, a method for facilitating identification of a transaction source partition is provided. An input/output transaction that is directed to a physical adapter is originated from a system image of a plurality of system images. The host data processing system adds an identifier of the system image to the input/output transaction. The input/output transaction is then conveyed to the physical adapter for processing of the input/output transaction.
