Linux在保护模式下的中断处理分析

Analysis of Linux Interrupt Procedure Based on Protected Mode

该文以80x86保护模式下的中断处理方法为基础,针对Linux在实时嵌入式系统中的具体应用,阐述Linux在保护模式下的中断及其中断响应处理过程,深入地分析Linux下的中断描述符初始化过程及中断处理程序的实现,最后通过Linux可加载内核模块编程对所作的分析进行验证。

Based on interrupt processing of80x86protected mode,the paper expatiates on interrupt and its processing,analyzes initialization of interrupt descriptor and implementation of interrupt processing in detail,finally validates the analysis by loadable kernel module programming.
