在调用driver_register()往设备驱动程序模型中插入一个新的device_driver对象时,driver_register()函数会调用bus_add_driver()函数,bus_add_driver()调用kobject_set_name()函数将name赋给drv>或者drv->kobj.k_name。 注:drv为要调用driver_register()注册的device_driver类型的对象。 2、struct bus_type *bus;...

在最低层, Linux 系统中的每个设备由一个 struct device 代表: struct device { struct device *parent; struct kobject kobj; char bus_id[BUS_ID_SIZE]; struct bus_type *bus; struct device_driver *driver; void *driver_data; void (*release)(struct device *dev); /* Several fields omitted */...

每个phy 芯片会创建一个 struct phy_device 类型的设备,对应的有 struct phy_driver 类型的驱动,这两者实际上是挂载在 mdio_bus_type 总线上的,mac 会被注册成 struct net_device。 phy_devicestructphy_device{ structphy_driver*drv;// PHY设备驱动 ...
