在Linux内核中,struct device对象的定义如下: ``` struct device { struct device *parent; struct device_private *p; struct kobject kobj; const char *init_name; struct device_type *type; struct bus_type *bus; struct driver *driver; void *platform_data; struct dev_archdata *archdata; void *...
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 */...

.probe = i2c_device_probe, .remove = i2c_device_remove, .shutdown = i2c_device_shutdown, }; 当这个模块被加载进系统时,就会执行i2c_init函数来进行初始化。 struct bus_type结构体描述了linux中的各种bus,比如spi bus,i2c bus,platform bus等等,可以看到,在i2c_bus_type中,定义了match(),probe(),re...
1.分配一个网络设备函数,即分配一个struct net_device结构体: alloc_netdev(sizeof_priv, name, setup); 这个alloc_netdev()函数本质上是一个宏定义: #define alloc_netdev(sizeof_priv, name, setup) \ alloc_netdev_mq(sizeof_priv, name, setup, 1) ...

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 ...
