Study on Defects Relate to Device Driver in Monolithic Kernel of Operating System
单一内核操作系统设备驱动程序缺陷研究

Device drivers arc major and easier faulty part of kernel. Especially in monolithic kernel of operating system,device drivers execute in supervisor mode, defects in device drivers usually result in kernel panic, greatly degrade the availability of operating system Defects in device drivers were analyzed and sorted, methods of reducing defects in device driver were introduced.
