Description: LINUX设备驱动程序第三版配套源码；
设备驱动最通俗的解释就是“驱使硬件设备行动”。驱动与底层硬件直接打交道，按照硬件设备的具体工作方式，读写设备的寄存器，完成设备的轮询、中断处理、DMA通信，进行物理内存向虚拟内存的映射等，最终让通信设备能收发数据，让显示设备能显示文字和画面，让存储设备能记录文件和数据。-LINUX device drivers third edition of the supporting source Device Driver is the most popular explanation is " driven by the actions of hardware. The drive deal directly with the underlying hardware, the read and write devices work in accordance with the specific hardware register, complete the device polling, interrupt handling, DMA communication, physical memory to virtual memory mapping, and ultimately allow communication device can send and receive data , so that the display device can display text and pictures, log file and data storage equipment.
