ABSTRACT:
A method, computer program product, and distributed data processing system that enables host software or firmware to map PCI adapter virtual resources to PCI bus addresses that are associated with a system image is provided. Virtual addresses maintained in a protection table segment assigned to a system image are mapped to physical addresses defined in entries of an address table segment assigned to the system image. Discontiguous memory regions identified in entries of the address table segment may thus be mapped to a contiguous virtual address space.
