4.2 Device Mapping
Each component in the processor is uniquely identified by a PCI bus address consisting
of Bus Number, Device Number and Function Number. Device configuration is based on
the PCI Type 0 configuration conventions. All processor registers appear on the PCI bus
assigned for the processor socket. Bus number is derived by the max bus range setting
and processor socket number.
