windows 中断处理学习笔记

标签：

学习计算机原理和操作系统课程之后，希望能对一个目前流行的操作系统有一些更深层的了解，正好认识一位朋友在做这方面的研究，在他的指点下，我希望通过windbg强大的调试功能，结合书本学到的知识，对windows(Windows 7 Kernel Version 7601 (Service Pack 1) MP (1 procs) Free x64)有一些了解。

鉴于本人对操作系统的认识有限，如有错误请批评指正。

一、中断处理程序

在计算机科学中，中断（英语：Interrupt）是指处理器接收到来自硬件或软件的信号，提示发生了某个事件，应该被注意，这种情况就称为中断。

通常，在接收到来自外围硬件（相对于中央处理器和内存）的异步信号，或来自软件的同步信号之后，处理器将会进行相应的硬件／软件处理。发出这样的信号称为进行中断请求（interrupt request，IRQ）。硬件中断导致处理器通过一个运行信息切换（context switch）来保存执行状态（以程序计数器和程序状态字等寄存器信息为主）；软件中断则通常作为CPU指令集中的一个指令，以可编程的方式直接指示这种运行信息切换，并将处理导向一段中断处理代码。中断在计算机多任务处理，尤其是即时系统中尤为有用。这样的系统，包括运行于其上的操作系统，也被称为“中断驱动的”（interrupt-driven）。（以上来自维基百科https://zh.wikipedia.org/wiki/%E4%B8%AD%E6%96%B7）。

处理中断是比较复杂的任务，硬件很难完成，目前来说都是由操作系统完成的。大致过程如下：

1.CPU接受到中断，原本执行的任务暂停执行

2.操作通过IDT（中断描述符表）找到对应的中断处理程序

3.调用中断处理程序

4.回到原来执行的任务或者结束原来的进程

 上面这个过程是极其不详细，不严谨的。实际的过程我们通过单步windows的中断处理程序来研究。

二、如何调试windows内核

windows调试内核态程序需要使用windbg通过串口进行双机调试(详细配置方法网上很多，不做过多的赘述)。为了方便操作，使用VM装了虚拟机，虚拟机的版本信息如下：

目前我也不能明白以上所有内容的意思，暂时将问题搁置。

 三、单步KiApicInterrupt：

由于刚刚起步，我并不清楚怎样完成这项工作。通过浏览windows internels和朋友的指点，在windbg通过!idt -a指令可以得到中断描述符表，内容如下：

x64和x86一样，也是同样支持0xff个中断（严格来说不只是中断）信号，上述表格正好有0xff项。让我比较困惑的是有些项有两个地址，目前暂时将问题搁置。然后通过bp KiApcInterrupt！指令在该函数入口地址设置断点，这样我们就成功的单步进来了。

四、对KiApcInterrupt函数机制的猜测（待续）
