# APIC

说实话对中断知之甚少，一方面用的少，另一方面对中断的硬件部分也了解的少。

借这个机会，通过对虚拟硬件的了解学习一下中断控制器。

随着技术的发展，现在有至少两种中断虚拟化的方式。

* [纯Qemu模拟](/understanding_qemu/00-advance_interrupt_controller/01-qemu_emulate.md)
* [Qemu/kernel混合模拟](/understanding_qemu/00-advance_interrupt_controller/02-qemu_kernel_emulate.md)

在第二种模拟的方式上，硬件又进一步做了辅助模拟

* [APICV](/understanding_qemu/00-advance_interrupt_controller/03-apicv.md)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://richardweiyang-2.gitbook.io/understanding_qemu/00-advance_interrupt_controller.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
