如何运行

这部分介绍如何现在获得源码，编译，指定运行参数等。生成IMG镜像，可以在QEMU模拟器上运行。

编译工具

1. 获得 Rust 相关工具

# 获得rustup
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# 获得rust所支持的所有架构相关
rustc --print target-list

# 增加LoongArch工具
rustup target add loongarch64-unknown-none

# 增加 cargo-binutils （objcopy, objdump）
cargo install cargo-binutils
rustup component add llvm-tools
#

2. 获取GNU GCC相关工具

git clone https://github.com/LoongsonLab/oscomp-toolchains-for-oskernel.git

tar zxf gcc-8.3.0-loongarch64-linux-gnu-rc1.1.novec.tgz

#增加环境变量
export PATH=${PATH}:/your-gcc-dir/bin

#测试工具
loongarch64-linux-gnu-gcc -v

3. 安装QEMU和binutils-gdb

# 在下载的oscomp-toolchains-for-oskernel中
tar zxf loongarch64-linux-gnu-gdb.tgz
tar zxf qemu.tgz

# 安装qemu所需要的依赖
sudo apt install libfdt-dev libcapstone-dev libspice-server-dev libsdl2-dev libusbredirparser1 libiscsi7 libaio1

# 增加环境变量
export PATH=${PATH}:/your-dir/bin

# 测试是否安装正确
loongarch64-linux-gnu-gdb -v
qemu-system-loongarch64 -M ?

代码获取

直接从LoongLAB的github上获取源码。

git clone https://github.com/LoongsonLab/StarryOS-LoongArch.git

获取的源码切换到main分支

制作镜像

cd StarryOS-LoongArch

./build_img.sh sdcard
#会在当前目录下生成 disk.img 文件

#可以查看文件类型
file disk.img

./build_img.sh sdcard会将testcases/sdcard的内容打包进disk.img

运行StarryOS

# 当前目录为StarryOS-LoongArch
# 编译内核
make ARCH=loongarch64 TARGET=loongarch64-qemu-virt A=apps/oscomp

# 运行内核
make run ARCH=loongarch64 TARGET=loongarch64-qemu-virt A=apps/oscomp

其中 ARCH指定架构类型。target指定平台，目前有两个平台支持，loongarch64-qemu-virt为Qemu模拟器平台，而loongarch64-2k1000是为2k1000开发板的配置。 A指定的是运行的哪一个应用，在目录apps/下有诸多目录，其中oscomp为比赛使用的应用，是入口main函数。

运行情况如下：

qemu-system-loongarch64 -m 16G -smp 1 -machine virt -kernel apps/oscomp/oscomp_loongarch64-qemu-virt.elf -nographic -vga none
