摘要
本文介绍了Linux操作系统的优点,以及设备驱动程序在Linux系统中的重要作用,并对Linux操作系统字符设备驱动程序的开发进行了研究,详细描述了Linux系统下字符设备驱动开发的设计方法和实现过程,包括设备驱动模块加载和卸载、设备的操作。在字符设备驱动的基础上,总结了产生竞态的几种情况,并提出了控制方法,说明了并发控制对驱动程序开发的重要性。
this paper introduces the advantage of Linux system and what important the device drivers it is in the Linux system,researches the development of the character device drivers based on Linux system,describes design method and design process of the character device driver,including device driver module load and module unload,device operation. On the base of the character device driver, summarizes several cases of generating race,proposeS the way of the control,describes the imprtance of concurrency control for the driver development.
