 现在我们了解了一些关于各种类型的中断和异常的内容，是时候转到更实用的部分了。我们从 `中断描述符表` 开始。就如之前所提到的，`IDT` 保存了中断和异常处理程序的入口指针。`IDT` 是一个类似于 `全局描述符表（Global Descriptor Table）`的结构，我们在[内核启动程序](http://0xax.gitbooks.io/linux-insides/content/Booting/linux-bootstrap-2.html)的第二部分已经介绍过。但是他们确实有一些不同，`IDT` 的表项被称为 `门（gates）`，而不是 `描述符（descriptors）`。

 in the `x86` architecture. Only [long mode](http://en.wikipedia.org/wiki/Long_mode) interrupt gates and trap gates can be referenced in the `x86_64`. Like the `Global Descriptor Table`, the `Interrupt Descriptor table` is an array of 8-byte gates on `x86` and an array of 16-byte gates on `x86_64`. We can remember from the second part of the [Kernel booting process](http://0xax.gitbooks.io/linux-insides/content/Booting/linux-bootstrap-2.html), that `Global Descriptor Table` must contain `NULL` descriptor as its first element. Unlike the `Global Descriptor Table`, the `Interrupt Descriptor Table` may contain a gate; it is not mandatory. For example, you may remember that we have loaded the Interrupt Descriptor table with the `NULL` gates only in the earlier [part](http://0xax.gitbooks.io/linux-insides/content/Booting/linux-bootstrap-3.html) while transitioning into [protected mode](http://en.wikipedia.org/wiki/Protected_mode):
