2023年秋冬季开源操作系统训练营第二阶段的日常学习记录
由于本人对Arch常规使用较为熟悉，所以选择了，物理机Arch & WSL2Arch 这样的配合，通常情况使用WSL2Arch，如果实验时存在未知情况，那么物理机Arch做为备用环境。
*WSL2使用了WIN自带的VM组件，这会导致与vmware等非WIN的VM之间的冲突
为了便于实验环境的更加顺畅的构建与使用，尽量避免鬼打墙的情况，所以有必要使用相关配置的国内镜像，本人泛用tuna，sjtu，ustc。
使用命令
$ vim /etc/pacman.conf
打开pacman配置文件
追加
[archlinuxcn] Server = https://mirrors.ustc.edu.cn/archlinuxcn/$arch
到文件末尾
$ sudo pacman -S qemu-full # version : 8.1.2-1
$ sudo pacman -S riscv64-elf-binutils # vesion : 2.39-1
$ sudo pacman -S riscv64-elf-gcc # version : 12.2.0-1
$ sudo pacman -S riscv64-elf-gdb # version : 13.1-2
$ sudo pacman -S riscv64-elf-newlib # version : 4.1.0-3
*其中 riscv64-elf-newlib 的安装描述为 "A C standard library implementation intended for use on embedded systems (RISCV64 bare metal)"，不知道有没有用，先装上。
使用命令
$ vim ~/.bashrc
打开本地用户bash配置文件，并追加
export RUSTUP_DIST_SERVER=https://mirrors.ustc.edu.cn/rust-static
export RUSTUP_UPDATE_ROOT=https://mirrors.ustc.edu.cn/rust-static/rustup
到文件.bashrc末尾
使用命令
$ vim ~/.cargo/config
开打cargo配置文件，并使用如下配置替换填充config内容:
[source.crates-io]
registry = "https://github.com/rust-lang/crates.io-index"
#replace-with = 'tuna'
#replace-with = 'sjtu'
replace-with = 'ustc'
[source.tuna]
registry = "https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index.git"
[source.ustc]
registry = "git://mirrors.ustc.edu.cn/crates.io-index"
[source.sjtu]
registry = "https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index"
[source.rustcc]
registry = "git://crates.rustcc.cn/crates.io-index"
$ rustup default nightly
$ rustup target add riscv64gc-unknown-none-elf
$ rustup component add llvm-tools-x86_64-unknown-linux-gnu
$ rustup component add rust-docs-x86_64-unknown-linux-gnu
$ rustup component add rust-src
$ rustup component add rust-std-riscv64gc-unknown-none-elf
使用命令
$ git clone https://github.com/rcore-os/rCore-Tutorial-v3.git
将rCore原始项目克隆到本地，
使用命令
$ cd rCore-Tutorial-v3
$ cd os
$ make run
编译运行出现：

clone & push 时相对顺畅些，也要多try几次。
