Linux Device Driver 3 (LDD3) is a comprehensive guide that provides practical examples and detailed explanations of how to develop device drivers for the Linux kernel. It covers a wide range of topics including character drivers, block drivers, USB drivers, network drivers, memory management, kerne...

一切皆文件,一个kernel可能包含多个文件系统,比如 存储硬盘被抽象成ext3文件系统 ⑤ 网络: 网络功能必须用操作系统来管理,因为大部分的网络操作和具体的进程无关:数据包的传入是异步事件 设备以及模块的分类: 模块: 内核模块可以随时载入到系统中,即便系统已经处于运行状态,通常使用的方法是insmod加载,rmmod卸载 ...
struct device_driver *driver; //管理该设备的驱动程序。 void *driver_data; //有设备驱动程序使用的私有数据成员 void (*release)(struct device *dev);//当指向设备的最后一个引用被删除时,内核调用该方法 ... }; 在注册device结构前,至少要设置parent、bus_id、bus和release成员 ...

they hide completely the details of how the device works. User activities are performed by means of a set of standardized calls that are independent of the specific driver; mapping those calls to device-specific operations that act on real hardware is then the role of the device driver. This...
