# 实验总体流程
|
||||
1. 在[学堂在线](https://www.xuetangx.com/courses/TsinghuaX/30240243X/2015_T1/about)查看OS相关原理和labX的视频;
|
||||
2. 可进一步在[学堂在线](https://www.xuetangx.com/courses/TsinghuaX/30240243X/2015_T1/info)或[在线操作系统课程练习题](https://chyyuu.gitbooks.io/os_course_exercises/content/)完成相关的练习题;如碰到问题,在[在线OS课程问题集](https://chyyuu.gitbooks.io/os_course_qa/content/)查找是否已经有解答;
|
||||
3. 在[实验指导书 on gitbook](https://chyyuu.gitbooks.io/ucore_os_docs/content/)上阅读实验指导书,并参考其内容完成练习和实验报告;
|
||||
4. 在实验环境中完成实验并提交实验到git server(清华学生需要在学校内部的git server上,其他同学可提交在其他git server上);
|
||||
5. 每天(一周七日)都有助教或老师在piazza在线答疑。如在[在线OS课程问题集](https://chyyuu.gitbooks.io/os_course_qa/content/)没找到解答,可到[piazza在线OS课程问答和交流区](https://piazza.com/tsinghua.edu.cn/spring2015/30240243x/home)提问。(QQ群 181873534主要用于本课程和OS相关事件发布,以及各种一般性交流);
|
||||
|
||||
|
||||
## 四种学习目标和对应手段
|
||||
1. 略知OS基本概念:看在线课程原理部分的视频,可大致知道OS的概念;
|
||||
2. 理解OS基本原理:在1的基础上,完成[学堂在线练习题](https://www.xuetangx.com/courses/TsinghuaX/30240243X/2015_T1/info)和[与OS原相关的在线操作系统课程练习题](https://chyyuu.gitbooks.io/os_course_exercises/content/),可理解OS基本原理
|
||||
3. 掌握OS设计实现:在2的基础上,能够通过编程完成labcodes的8个lab实验中的基本练习和实验报告
|
||||
4. 深入OS核心功能:在3的基础上,能够通过编程完成labcodes的8个lab实验中的challenge练习
|
||||
5. 体验OS科学研究:在4的基础上,能够通过阅读论文、设计、编程、实验评价等过程来完成课程设计(大实验)
|
||||
|
||||
【**注意**】
|
||||
- **筑基内功**--请提前学习计算机原理、C语言、数据结构课程
|
||||
- **工欲善其事,必先利其器**--请掌握七种武器 [实验常用工具列表](https://github.com/chyyuu/ucore_docs/blob/master/lab0/lab0_ref_ucore-tools.md)
|
||||
- **学至于行之而止矣**--请在实验中体会操作系统的精髓
|
||||
- **打通任督二脉**--lab1和lab2与x86硬件相关性较大,比较困难,有些同学由于畏难而止步与此,很可惜!仅仅熟读内功心法是不够的,通过实践lab1和lab2后,对计算机原理中的中断、段页表机制、特权级等的理解会更深入和贴近实际,这等同于打通了任督二脉,后面的实验将一片坦途。

## 实验环境
|
||||
ucore OS实验主要在Linux环境下开发,有如下五种方法。
|
||||
|
||||
### 一、[在线实验--基于"实验楼"在线平台](http://www.shiyanlou.com/courses/221)
|
||||
特点:不用在本机配置环境或安装虚拟机,你需要的是可以可以上网的网络浏览器,实验都可在网上完成!感谢[实验楼](http://www.shiyanlou.com/)提供的支持!
|
||||
|
||||
### 二、Windows下基于MingW进行实验
|
||||
特点:可在Windows环境下完成实验。不用安装Linux,只需在Windows上安装相关软件即可。
|
||||
|
||||
- [windows下的ucore实验环境安装包](http://pan.baidu.com/s/1qWPtHxy):下载安装即可。感谢杨海宇同学提供!
|
||||
- [windows下手动配置ucore实验环境说明文档](http://pan.baidu.com/s/1i3JxZZR):看你的安装能力。感谢“下来障”同学提供!
|
||||
|
||||
[NOTICE] 没有足够的技术支持,希望有感兴趣的生成一个安装软件包和中文使用说明,方便大家使用!
|
||||
|
||||
### 三、Windows下基于VirtualBox or VMWare进行实验
|
||||
特点:可在Windows环境下完成实验。不用安装Linux,安装VirtualBox等虚拟机软件即可,可以用已经配好环的虚拟硬盘。安装简单,但性能受一定影响。
|
||||
|
||||
#### 1. 安装VirtualBox or VMWare软件
|
||||
|
||||
VirtualBox虚拟机软件
|
||||
|
||||
https://www.virtualbox.org/
|
||||
|
||||
[NOTICE] 也可以安装vmware虚拟机软件
|
||||
|
||||
#### 2.使用已经预先安装好相关实验环境所需软件的虚拟硬盘
|
||||
|
||||
并下载已经安装好ubuntu 14.04 x86-64的虚拟硬盘文件压缩包。
|
||||
[VirtualBox的虚拟硬盘文件压缩包2015版](http://pan.baidu.com/s/11zjRK)
|
||||
|
||||
--------------
|
||||
|
||||
压缩包可以用[haozip for windows软件](http://www.haozip.com)解压。解压压缩包后,可得到如下内容(大约6GB多)。
|
||||
```
|
||||
mooc-os-2015-2.vdi
|
||||
```
|
||||
|
||||
如果此时你已经安装好了VirtualBox, 就可以在VirtualBox模拟的x86-64计算机中新建一个虚拟机(配置为ubuntu linux x86 64bit),并指定此虚拟机的虚拟硬盘为你刚才解压的vdi文件。创建完虚拟机后,就可以运行此虚拟幻镜,并可以开始学习
|
||||
ucore OS实验了。
|
||||
```
|
||||
用户名是 moocos
|
||||
口令是 <空格键>
|
||||
```
|
||||
|
||||
> [NOTICE] 如果正确安装了virtualbox并配置好虚拟机,但无法运行虚拟机或无法加入虚拟硬盘, 可以尝试删除virtualbox的一些配置目录,比如:
|
||||
```
|
||||
C:\Users\VirtualBox VMs\
|
||||
```
|
||||
|
||||
建议a: 设置虚拟硬盘的大小为8GB以上,虚拟内存在1B以上。
|
||||
建议b: 如果你的机器安装的是32位的windows,则下载32位的ubuntu 14.04 32bit img镜像。
|
||||
|
||||
|
||||
### 四、在MAC OS下进行实验
|
||||
|
||||
感谢 altkatz!
|
||||
|
||||
Using gcc49
|
||||
|
||||
#### 1.install [homebrew](http://brew.sh/)
|
||||
|
||||
#### 2.install binutils, gcc, gdb targeting i386-elf
|
||||
|
||||
* `brew tap altkatz/homebrew-gcc_cross_compilers`
|
||||
* `brew install i386-elf-gcc` # may take an hour
|
||||
* `brew install i386-elf-gdb`
|
||||
|
||||
#### 3. install qemu-system-i386
|
||||
|
||||
* `brew install qemu`
|
||||
|
||||
### 五、手动在物理PC中安装环境
|
||||
|
||||
|
||||
-------------------------------------
|
||||
特点:性能最好,但安装有一定难度,需要对Linux比较熟悉
|
||||
|
||||
(这里假定安装的要是ubuntu14.04 x86-64的系统)
|
||||
|
||||
1) 在物理PC上安装ubuntu
|
||||
|
||||
下载ubuntu 14.04 64bit img镜像,需要把镜像刻录到可启动的光盘或闪盘中,把光盘或闪盘放入物理PC,并在物理PC上重启安装。
|
||||
|
||||
2) 在ubuntu系统中安装实验环境相关软件
|
||||
在shell(比如gnome-terminal)下可执行如下命令来安装相关软件 (“$”是shell的提示符,不用输入)
|
||||
```
|
||||
$ sudo apt-get update
|
||||
$ sudo apt-get upgrade
|
||||
$ sudo apt-get install build-essential git qemu-system-x86 vim-gnome gdb cgdb eclipse-cdt make diffutils exuberant-ctags tmux openssh-server cscope meld qgit gitg gcc-multilib gcc-multilib g++-multilib
|
||||
```
|
||||
[NOTICE] 最小需要的安装包: build-essential git qemu-system-x86 gdb make diffutils gcc-multilib
|
||||
|
||||
[NOTICE] 如要源码编译qemu,需要执行 `apt-get install zlib1g-dev libsdl1.2-dev libesd0-dev automake`
|
||||
|
||||
## 实验中的练习步骤
|
||||
以VirtualBox为例,进入VirtualBox中运行的ubuntu,点击左侧的gnome-terminal软件图标,可启动gnome-terminal
|
||||
软件。在此软件中,执行如下命令:
|
||||
|
||||
1) 目前环境中已经有ucore lab源码,可进一步取得最新ucore lab源码
|
||||
```
|
||||
$cd moocos/ucore_lab #到ucore lab所在目录
|
||||
$git pull #取得最新的ucore lab源代码
|
||||
$cd
|
||||
```
|
||||
|
||||
2) 学习源码
|
||||
```
|
||||
$cd labX #X为 1--8
|
||||
```
|
||||
|
||||
3) 阅读,修改源码,可以用eclipse-cdt, understand, gedit或vim软件
|
||||
```
|
||||
$eclipse
|
||||
OR
|
||||
$understand
|
||||
```
|
||||
|
||||
4) 修改完毕后,编译实验代码
|
||||
```
|
||||
$make
|
||||
```
|
||||
|
||||
5) 如果编译无误,则可以运行测试一下
|
||||
```
|
||||
$make qemu
|
||||
```
|
||||
|
||||
6) 如果需要调试,
|
||||
|
||||
a. 可基于cgdb的字符方式(以lab1_ans为例)
|
||||
```
|
||||
$cd labcodes_answer/lab1_ans
|
||||
$make debug
|
||||
```
|
||||
可以看到弹出两个窗口,一个是qemu,一个是cgdb
|
||||
可以看到在bootloader的bootmain函数处停了下来。
|
||||
然后我们就可以进一步在cgdb中用gdb的命令进行调试了
|
||||
```
|
||||
(gdb)file bin/kernel #加载ucore kernel的符号信息
|
||||
(gdb)break kern_init #在函数kern_init处(即 0x100000地址处)设置断点
|
||||
(gdb)continue #继续执行
|
||||
```
|
||||
这时就可以看到在kern_init处停了下来,可进一步调试。
|
||||
|
||||
b. 基于eclipse-CDT的debug view进行调试,如果安装了zylin debug插件,则完成初步配置后,
|
||||
也可很方便地进行调试。
|
||||
|
||||
7) 可以运行如下命令,看看自己的得分
|
||||
```
|
||||
$make grade
|
||||
```
|
||||

|
||||
2. 理解OS基本原理:在1的基础上,完成[学堂在线练习题](https://www.xuetangx.com/courses/TsinghuaX/30240243X/2015_T1/info)和[与OS原相关的在线操作系统课程练习题](https://chyyuu.gitbooks.io/os_course_exercises/content/),可理解OS基本原理
|
||||
3. 掌握OS设计实现:在2的基础上,能够通过编程完成labcodes的8个lab实验中的基本练习和实验报告
|
||||
4. 深入OS核心功能:在3的基础上,能够通过编程完成labcodes的8个lab实验中的challenge练习
|
||||
5. 体验OS科学研究:在4的基础上,能够通过阅读论文、设计、编程、实验评价等过程来完成课程设计(大实验)
|
||||
|
||||
【**注意**】
|
||||
- **筑基内功**--请提前学习计算机原理、C语言、数据结构课程
|
||||
- **工欲善其事,必先利其器**--请掌握七种武器 [实验常用工具列表](https://github.com/chyyuu/ucore_docs/blob/master/lab0/lab0_ref_ucore-tools.md)
|
||||
- **学至于行之而止矣**--请在实验中体会操作系统的精髓
|
||||
- **打通任督二脉**--lab1和lab2与x86硬件相关性较大,比较困难,有些同学由于畏难而止步与此,很可惜!仅仅熟读内功心法是不够的,通过实践lab1和lab2后,对计算机原理中的中断、段页表机制、特权级等的理解会更深入和贴近实际,这等同于打通了任督二脉,后面的实验将一片坦途。

## 实验环境
|
||||
ucore OS实验主要在Linux环境下开发,有如下五种方法。
|
||||
|
||||
### 一、[在线实验--基于"实验楼"在线平台](http://www.shiyanlou.com/courses/221)
|
||||
特点:不用在本机配置环境或安装虚拟机,你需要的是可以可以上网的网络浏览器,实验都可在网上完成!感谢[实验楼](http://www.shiyanlou.com/)提供的支持!
|
||||
|
||||
### 二、Windows下基于MingW进行实验
|
||||
特点:可在Windows环境下完成实验。不用安装Linux,只需在Windows上安装相关软件即可。
|
||||
|
||||
- [windows下的ucore实验环境安装包](http://pan.baidu.com/s/1qWPtHxy):下载安装即可。感谢杨海宇同学提供!
|
||||
- [windows下手动配置ucore实验环境说明文档](http://pan.baidu.com/s/1i3JxZZR):看你的安装能力。感谢“下来障”同学提供!
|
||||
|
||||
[NOTICE] 没有足够的技术支持,希望有感兴趣的生成一个安装软件包和中文使用说明,方便大家使用!
|
||||
|
||||
### 三、Windows下基于VirtualBox or VMWare进行实验
|
||||
特点:可在Windows环境下完成实验。不用安装Linux,安装VirtualBox等虚拟机软件即可,可以用已经配好环的虚拟硬盘。安装简单,但性能受一定影响。
|
||||
|
||||
#### 1. 安装VirtualBox or VMWare软件
|
||||
|
||||
VirtualBox虚拟机软件
|
||||
|
||||
https://www.virtualbox.org/
|
||||
|
||||
[NOTICE] 也可以安装vmware虚拟机软件
|
||||
|
||||
#### 2.使用已经预先安装好相关实验环境所需软件的虚拟硬盘
|
||||
|
||||
并下载已经安装好ubuntu 14.04 x86-64的虚拟硬盘文件压缩包。
|
||||
[VirtualBox的虚拟硬盘文件压缩包2015版](http://pan.baidu.com/s/11zjRK)
|
||||
|
||||
--------------
|
||||
|
||||
压缩包可以用[haozip for windows软件](http://www.haozip.com)解压。解压压缩包后,可得到如下内容(大约6GB多)。
|
||||
labs info
|
||||
----------------
|
||||
```
|
||||
mooc-os-2015-2.vdi
|
||||
lab0: preparing
|
||||
lab1: boot/protect mode/stack/interrupt
|
||||
lab2: physical memory management
|
||||
lab3: virtual memory management
|
||||
lab4: kernel thread management
|
||||
lab5: user process management
|
||||
lab6: scheduling
|
||||
lab7: mutex/sync
|
||||
lab8: filesystem
|
||||
```
|
||||
|
||||
如果此时你已经安装好了VirtualBox, 就可以在VirtualBox模拟的x86-64计算机中新建一个虚拟机(配置为ubuntu linux x86 64bit),并指定此虚拟机的虚拟硬盘为你刚才解压的vdi文件。创建完虚拟机后,就可以运行此虚拟幻镜,并可以开始学习
|
||||
ucore OS实验了。
|
||||
TESTED ENVIRONMENT
|
||||
==================
|
||||
```
|
||||
用户名是 moocos
|
||||
口令是 <空格键>
|
||||
UBUNTU 14.04+: GCC-4.8.2+ CLANG-3.5+
|
||||
FEDORA 20+: GCC-4.8.2+
|
||||
```
|
||||
|
||||
> [NOTICE] 如果正确安装了virtualbox并配置好虚拟机,但无法运行虚拟机或无法加入虚拟硬盘, 可以尝试删除virtualbox的一些配置目录,比如:
|
||||
```
|
||||
C:\Users\VirtualBox VMs\
|
||||
```
|
||||
|
||||
建议a: 设置虚拟硬盘的大小为8GB以上,虚拟内存在1B以上。
|
||||
建议b: 如果你的机器安装的是32位的windows,则下载32位的ubuntu 14.04 32bit img镜像。
|
||||
|
||||
|
||||
### 四、在MAC OS下进行实验
|
||||
|
||||
感谢 altkatz!
|
||||
|
||||
Using gcc49
|
||||
|
||||
#### 1.install [homebrew](http://brew.sh/)
|
||||
|
||||
#### 2.install binutils, gcc, gdb targeting i386-elf
|
||||
|
||||
* `brew tap altkatz/homebrew-gcc_cross_compilers`
|
||||
* `brew install i386-elf-gcc` # may take an hour
|
||||
* `brew install i386-elf-gdb`
|
||||
|
||||
#### 3. install qemu-system-i386
|
||||
|
||||
* `brew install qemu`
|
||||
|
||||
### 五、手动在物理PC中安装环境
|
||||
|
||||
|
||||
-------------------------------------
|
||||
特点:性能最好,但安装有一定难度,需要对Linux比较熟悉
|
||||
|
||||
(这里假定安装的要是ubuntu14.04 x86-64的系统)
|
||||
|
||||
1) 在物理PC上安装ubuntu
|
||||
|
||||
下载ubuntu 14.04 64bit img镜像,需要把镜像刻录到可启动的光盘或闪盘中,把光盘或闪盘放入物理PC,并在物理PC上重启安装。
|
||||
|
||||
2) 在ubuntu系统中安装实验环境相关软件
|
||||
在shell(比如gnome-terminal)下可执行如下命令来安装相关软件 (“$”是shell的提示符,不用输入)
|
||||
```
|
||||
$ sudo apt-get update
|
||||
$ sudo apt-get upgrade
|
||||
$ sudo apt-get install build-essential git qemu-system-x86 vim-gnome gdb cgdb eclipse-cdt make diffutils exuberant-ctags tmux openssh-server cscope meld qgit gitg gcc-multilib gcc-multilib g++-multilib
|
||||
```
|
||||
[NOTICE] 最小需要的安装包: build-essential git qemu-system-x86 gdb make diffutils gcc-multilib
|
||||
|
||||
[NOTICE] 如要源码编译qemu,需要执行 `apt-get install zlib1g-dev libsdl1.2-dev libesd0-dev automake`
|
||||
|
||||
## 实验中的练习步骤
|
||||
以VirtualBox为例,进入VirtualBox中运行的ubuntu,点击左侧的gnome-terminal软件图标,可启动gnome-terminal
|
||||
软件。在此软件中,执行如下命令:
|
||||
|
||||
1) 目前环境中已经有ucore lab源码,可进一步取得最新ucore lab源码
|
||||
```
|
||||
$cd moocos/ucore_lab #到ucore lab所在目录
|
||||
$git pull #取得最新的ucore lab源代码
|
||||
$cd
|
||||
```
|
||||
|
||||
2) 学习源码
|
||||
```
|
||||
$cd labX #X为 1--8
|
||||
```
|
||||
|
||||
3) 阅读,修改源码,可以用eclipse-cdt, understand, gedit或vim软件
|
||||
```
|
||||
$eclipse
|
||||
OR
|
||||
$understand
|
||||
```
|
||||
|
||||
4) 修改完毕后,编译实验代码
|
||||
EXERCISE STEPS
|
||||
==============
|
||||
```
|
||||
0 Get the newest os lab src codes/docs.(Insure you can connect to github in ubuntu running on VrtualBox)
|
||||
0.1 If you try to get all codes
|
||||
$rm -rf ucore_lab
|
||||
$git clone git://github.com/chyyuu/ucore_os_lab.git
|
||||
$cd ucore_lab
|
||||
0.2 If you gloned ucore_lab and only try to get the updated codes
|
||||
$cd ucore_os_lab
|
||||
$git pull
|
||||
1 $cd labX
|
||||
2 read codes (specially the modified or added files)
|
||||
3 add your code
|
||||
4 compile your code
|
||||
$make
|
||||
```
|
||||
|
||||
5) 如果编译无误,则可以运行测试一下
|
||||
```
|
||||
5 check your code
|
||||
$make qemu
|
||||
```
|
||||
|
||||
6) 如果需要调试,
|
||||
|
||||
a. 可基于cgdb的字符方式(以lab1_ans为例)
|
||||
```
|
||||
$cd labcodes_answer/lab1_ans
|
||||
$make debug
|
||||
```
|
||||
可以看到弹出两个窗口,一个是qemu,一个是cgdb
|
||||
可以看到在bootloader的bootmain函数处停了下来。
|
||||
然后我们就可以进一步在cgdb中用gdb的命令进行调试了
|
||||
```
|
||||
(gdb)file bin/kernel #加载ucore kernel的符号信息
|
||||
(gdb)break kern_init #在函数kern_init处(即 0x100000地址处)设置断点
|
||||
(gdb)continue #继续执行
|
||||
```
|
||||
这时就可以看到在kern_init处停了下来,可进一步调试。
|
||||
|
||||
b. 基于eclipse-CDT的debug view进行调试,如果安装了zylin debug插件,则完成初步配置后,
|
||||
也可很方便地进行调试。
|
||||
|
||||
7) 可以运行如下命令,看看自己的得分
|
||||
```
|
||||
OR
|
||||
$make grade
|
||||
|
||||
6 debug your code
|
||||
$make debug
|
||||
|
||||
7 handin your code
|
||||
$make handin
|
||||
```
