Linux设备驱动程序自动更新及辅助工具

Automatic Updating and Auxiliary Tools of Linux Device Drivers

研究了Linux设备驱动程序的自动更新方法,建立了基于源码的Linux设备驱动辅助更新模型,设计并实现了一组相应的自动更新支撑工具,包括Linux设备驱动程序对内核依赖接口的分析工具、内核依赖接口差异性分析工具以及设备驱动更新辅助信息的生成工具.相关原型经测试验证表明,可以有效改善设备驱动开发和维护工作.另外,还提出了用于评估设备驱动辅助更新工作的量化指标即关于辅助更新提示信息的误报率和漏报率的概念及计算方法.

The automatic updating method of Linux device drivers is studied and the corresponding assisted updating model based on source codes is built while a set of tools to support automatic updating of drivers are designed and implemented.This set of tools includes a tool to extract kernel-dependent interfaces for the Linux device drivers,a tool to analyze differences between kernel-dependent interfaces for two versions of kernels,and a tool to generate helpful information for updating of device drivers.Related prototypes have been tested and the results show that it can effectively improve the development and maintenance of device drivers.In addition,the concepts and calculation methods for the rate of false reporting and the rate of missing reporting about helpful information for updating are put forward,which are to be used for the quantitative indicators to evaluate assisted updating for device drivers.
