所谓的"probe”,是指在Linux内核中,如果存在相同名称的device和device_driver,内核就会执行device_driver中的probe回调函数,而该函数就是所有driver的入口,可以执行诸如硬件设备初始化、字符设备注册、设备文件操作ops注册等动作("remove”是它的反操作,发生在device或者device_driver任何一方从内核注销时。
Linux Device的注册最终都是通过device_register()实现,Driver的注册最终都是通过driver_register()实现。下图对照说明了Device和Driver的注册过程。 上面的图解一目了然,详细过程不再赘述。注意以下几点说明: BUS的p->drivers_autoprobe;1默认是true。 bus_for_each_drv()是对BUS上所有的Driver都进行__device_attach...
