hit-linux-0.11's Introduction

操作系统代码实现及记录

details: 这是我在网易云课堂选的操作系统所要求的实验的代码及相关记录,授课老师是哈工大的李治军老师,李老师的讲课风格浅入深出,讲得非常好!我作为一个普通一本大学非计算机专业的学生,能接收到这样的教育,得感谢《网易云课堂》,感谢李治军老师。

update: 距离大三学习这门Mooc,已经过去两年了。现在我也算是如愿转到了计算机专业,目前来看自己最擅长的还是嵌入式领域,所以我想从之前停下来的地方开始,真正学好这门课,完成这八个实验,就像李老师所说,完成这八个实验,操作系统才算是入门了。希望自己早日完成这些实验,入门操作系统。 2017.03

0. 实验环境搭建

致谢DeathKing/hit-oslab项目,提供了Ubuntu环境下的实验环境的一键配置脚本及其所需的源代码,工具等材料。我在此基础上进行了一些小改动,使配置脚本可以在Ubuntu 16.04上使用。具体参见Linux 0.11实验环境准备

1. 操作系统的引导

参见操作系统的引导

2. 系统调用

参见系统调用

3. 进程运行轨迹的跟踪与统计

参见进程运行轨迹的跟踪与统计,修改时间片在我本地实验环境效果不明显,弃坑...,以后再研究是怎么回事:(

4. 基于内核栈切换的进程切换

参见基于内核栈切换的进程切换

5. 信号量的实现和应用

参见信号量的实现和应用

6. 地址映射与共享

7. 终端设备的控制

8. proc文件系统的实现
