When kernel startup, pci subsystem will create pci_bus for each physical PCI bus, then the pci_bus will be added to pci_root_buses(with PCI configuration). But pci device driver register driver bypci_register_driver, and it will add pci driver to pci_bus_type. My question ： • How does pci_bus_type know PCI configuration. • What is the relationship between pci_bus_type and pci_root_buses. Somebody help me? -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
