2.3 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.
