The SHub serves as a crossbar between the FSB, supporting 1 or 2 CPUs, the memory, the 2 NUMAlink network interfaces and the Xtalk I/O interface. Since the PCI/PCI-X host controllers connect to the SHub via the Xtalk interfaces, the shub driver will become the parent of the pci host controller driver. END
