Abstract: A first device is determined as connected to a first one of a plurality of ports of a root complex. Addresses are assigned corresponding to a first hierarchy of devices including the first device. A second device is determined as connected through a mapping portal bridge at a second one of the ports of the root complex, the second device included in another second hierarchy of devices. A mapping table is generated that corresponds to the mapping portal bridge. The mapping table defines a translation between addressing used in a first view of a configuration address space of the system and addressing used in a second view of the configuration address space. The first view includes a view of the root complex and the second view includes a view corresponding to the second hierarchy of devices, the first hierarchy of devices being addressed according to the first view.
