This project is the programming assignment of the class ICS(Introduction to Computer System) in Department of Computer Science and Technology, Nanjing University.
For the guide of this programming assignment, refer to https://jyywiki.cn/ICS/2021
To initialize, run
bash init.sh subproject-nameSee init.sh for more details.
The following subprojects/components are included. Some of them are not fully implemented.
sudo apt-get install build-essential # build-essential packages, include binary utilities, gcc, make, and so on
sudo apt-get install man # on-line reference manual
sudo apt-get install gcc-doc # on-line reference manual for gcc
sudo apt-get install gdb # GNU debugger
sudo apt-get install git # revision control system
sudo apt-get install libreadline-dev # a library used later
sudo apt-get install libsdl2-dev # a library used later
sudo apt-get install llvm # llvm project, which contains libraries used later
sudo apt-get install bison # bison
sudo apt-get install riscv64 # flex
sudo apt-get install flex # flex
sudo apt-get install ccache
sudo apt install gcc-riscv64-linux-gnu
sudo apt install g++-riscv64-linux-gnu
在~/.zshrc中加入下面两行
export NEMU_HOME=/home/bhx/work/ics2021/nemu
export AM_HOME=/home/bhx/work/ics2021/abstract-machine
export NAVY_HOME=/home/bhx/work/ics2021/navy-apps在nemu目录下执行
make menuconfig从网盘上下载文件，放入pal/repo/data目录下
写配置文件config.cfg放入pal/repo/data主要将材质和视图大小设置为320*200
在nanos-lite目录下执行
make ARCH=riscv32-nemu update会出现一个缺少头文件的报错，进入引用的头文件中注释掉即可。
在navy-apps/Makefile中设置
目前已完成全部必做内容
实现多道批处理系统。
支持运行仙剑、flappy bird、nslider、nterm等应用程序
基于虚存机制，实现分时系统。支持用户进程、操作系统、内核线程之间的并发执行
实现内核栈与用户栈的切换存储，支持用户进程之间的并发运行
PA2开始，由于版本问题，diffrential test无法支持
PA3的一些很有价值的选做：系统声卡、am环境迁移、多道程序ftracer
仙剑有两个已知的BUG，一个是战斗时卡死、一个是存档机制异常
busybox有BUG，会循环执行命令
