Dsysfs.md91 &emsp;&emsp;对于bus设备而言，需要调用bus_register，将bus注册进系统，并在sysfs中可视化。
94 /// @brief: 总线注册，将总线加入全局总线管理器中，并根据id table在sys/bus和sys/devices下生成文件夹
95 /// @parameter bus: Bus设备实体
97 pub fn bus_register<T: Bus>(bus: Arc<T>) -> Result<(), DeviceError> {
98 BUS_MANAGER.add_bus(bus.get_id_table(), bus.clone());
99 match sys_bus_register(&bus.get_id_table().to_name()) {

109 &emsp;&emsp;通过bus_register源码可知，该函数不仅在sysfs/bus下生成总线文件夹，同时内部调用device_register，该函数将总线加入设备管理器中，同时在sys/…
