Advanced Configuration and Power Interface Specification 9.11.1 Describing PCI Bus and Segment Group Numbers under Module Devices If a module device exposes one or more PCI root busses, OSPM must be able to determine what PCI bus and segment group numbers are defined for the module device. A module device may be a container for root buses in multiple segment groups. Because the _SEG method can only return a single number, _SEG cannot adequately describe this case. To properly convey this information to OSPM, the PCI bus number resource descriptor in the module device must include both the bus and segment resources produced by the module device. To describe this in systems that implement multiple PCI segment groups, the segment group resources produced by a module device must be encoded in bits 8 and higher of the module device’s WordBusNumber resource descriptor. For systems that do not expose multiple PCI segment groups, bits 8 and higher of the module device’s WordBusNumber resource descriptor must be zero. Note: The range of PCI segment groups reported in the _CRS of module devices cover both assigned and unassigned PCI root bridges. In the case of hot add of a PCI root bridge, OSPM does not reevaluate the _CRS of its parent module device as its resources are not expected to change in this case. For an example of a module device encoding PCI segment group ranges with PCI bus number resources, consider a module device that describes two PCI root bridges as child devices. The _CRS for the module device describes 2 PCI root bridges as child devices, where each PCI root bridge consumes its own PCI segment. Hewlett-Packard/Intel/Microsoft/Phoenix/Toshiba 455
