|
<p>zCore 是用 Rust 语言重写的 Zircon 微内核，它是 Google 正在开发的 Fuchsia OS 中的底层内核。</p>
|
|
|
<p>本教程基于 zCore 的真实开发历史，还原其开发过程。带领读者一步一步用 Rust 实现自己的 Zircon 内核，最终能够运行原生的 shell 程序。
|
|
|
在此过程中我们将体会 Zircon 微内核的设计理念，感受如何用 Rust 语言以一种现代的方式编写系统软件，在项目中实现理论与实践的融合。</p>
|
|
|
<p>与传统操作系统开发不同的是，zCore 使用一种自顶向下的方法：首先基于宿主系统已有的功能，在用户态实现一个能够工作的 libOS，然后再逐步替换底层实现，
|
|
|
"移植"回裸机环境中运行。因此我们更关注系统的整体设计，从高层视角看待 OS 如何为用户提供服务，而不纠结于底层硬件细节。</p>
|
|
|
<p>鉴于此，本教程假设读者了解操作系统基本概念和原理，具有常用的 Linux 系统使用经验，并且会使用 Rust 语言编写简单程序。
|
|
|
如果读者不熟悉操作系统和 Rust 语言，希望以自底向上方法从零构建操作系统，<a href="https://rcore-os.github.io/rCore-Tutorial-deploy/">rCore Tutorial</a> 可能是更好的选择。</p>
|
|
|
<p>如果你准备好了，让我们开始吧！</p>
