1. 环境搭建
我们基于Ubuntu22.04进行环境搭建需要安装编译内核的包和LLVM等包
sudo apt-get -y install binutils build-essential libtool texinfo gzip zip unzip patchutils curl git make cmake ninja-build automake bison flex gperf grep sed gawk bc zlib1g-dev libexpat1-dev libmpc-dev libglib2.0-dev libfdt-dev libpixman-1-dev libelf-dev libssl-dev clang-format clang-tidy clang-tools clang clangd libc-dev libc1 libcabi-dev libcabi1 libclang-dev libclang1 liblldb-dev libllvm-ocaml-dev libomp-dev libomp5 lld lldb llvm-dev llvm-runtime llvm python3-clang llvm2. 编译rust内核
2.1 下载源代码
git clone https://github.com/Rust-for-Linux/linux -b rust-dev我们使用Rust-for-Linux的rust-dev分支进行学习。
2.2 安装rust支持
cd linux-rust
rustup override set $(scripts/min-tool-version.sh rustc)
rustup component add rust-src
cargo install --locked --version $(scripts/min-tool-version.sh bindgen) bindgen-cli2.3 检查linux内核是否支持rust
jianjian:~/share/linux-rust$ make LLVM1 rustavailable
Rust is available!
2.4 编译linux内核
首先生成配置文件.config
make ARCHarm64 LLVM1 Obuild defconfig然后修改配置文件把CONFIG_RUST设置为y
make ARCHarm64 LLVM1 Obuild menuconfig最后编译内核
cd build make ARCHarm64 LLVM1 -j83. aarch64的qemu环境
3.1.下载源代码
https://download.qemu.org/qemu-7.0.0.tar.xz3.2. 解压编译安装
tar -xf qemu-7.0.0.tar.xz
cd qemu-7.0.0
mkdir build-aarch64 cd build-aarch64
../configure --target-listaarch64-softmmu,aarch64-linux-user
make -j $(nproc)3.3. 配置环境变量
在~/.bashrc文件中添加下面语句
export PATH$PATH:/home/jian/share/qemu/qemu-7.0.0/build-aarch64
export PATH$PATH:/home/jian/share/qemu/qemu-7.0.0/build-aarch64/aarch64-softmmu
export PATH$PATH:/home/jian/share/qemu/qemu-7.0.0/build-aarch64/aarch64-linux-user
3.4.验证
新开一个控制台输入下面
jianjian:~/share/qemu/qemu-7.0.0$ qemu-system-aarch64 --version
QEMU emulator version 7.0.0
Copyright (c) 2003-2022 Fabrice Bellard and the QEMU Project developers
jianjian:~/share/qemu/qemu-7.0.0$ qemu-aarch64 --version
qemu-aarch64 version 7.0.0
Copyright (c) 2003-2022 Fabrice Bellard and the QEMU Project developers
jianjian:~/share/qemu/qemu-7.0.0$
4. 准备debian文件系统
4.1 下载文件系统
去Debian官方网站上下载 Images for arm64-virt 版本的压缩包 https://people.debian.org/~gio/dqib/
4.2 解压缩
unzip arm64-virt.zip解压缩后可以看到下面的内容
jianjian:~/share/arm64-virt$ tree
.
├── arm64-virt.zip
└── dqib_arm64-virt├── Image├── image.qcow2├── initrd├── kernel├── mymake├── readme.txt├── ssh_user_ecdsa_key├── ssh_user_ed25519_key└── ssh_user_rsa_key1 directory, 10 files4.3 测试下载的内核和文件系统
执行下面的命令可以尝试把整个的debian文件系统跑起来
qemu-system-aarch64 -machine virt -cpu cortex-a57 -m 1G -device virtio-blk-device,drivehd -drive fileimage.qcow2,ifnone,idhd -device virtio-net-device,netdevnet -netdev user,idnet,hostfwdtcp::2222-:22 -kernel kernel -initrd initrd -nographic -append rootLABELrootfs consolettyAMA05. 运行自己编译的内核
5.1 拷贝自己编译的内核
cp ~/share/linux-rust/build/arch/arm64/boot/Image /home/jian/share/arm64-virt/dqib_arm64-virt5.2 运行自己编译的内核
qemu-system-aarch64 -machine virt -cpu cortex-a57 -m 1G -device virtio-blk-device,drivehd -drive fileimage.qcow2,ifnone,idhd -device virtio-net-device,netdevnet -netdev user,idnet,hostfwdtcp::2222-:22 -kernel Image -initrd initrd -nographic -append rootLABELrootfs consolettyAMA06. rust模块
6.1 编译linux中的rust用例
make ARCHarm64 LLVM1 Obuild menuconfig
cd build make ARCHarm64 LLVM1 -j8把CONFIG_SAMPLE_RUST_PRINT和CONFIG_SAMPLE_RUST_MINIMAL选上。然后在编译。 可以看到下面的输出
[ 2.836088] rust_minimal: Rust minimal sample (init)
[ 2.836386] rust_minimal: Am I built-in? true
[ 2.837094] rust_print: Rust printing macros sample (init)
[ 2.837225] rust_print: Emergency message (level 0) without args
[ 2.837379] rust_print: Alert message (level 1) without args

[ 2.838456] rust_print: Notice message (level 5) without args
[ 2.838579] rust_print: Info message (level 6) without args
[ 2.838712] rust_print: A line that is continued without args
[ 2.839166] rust_print: Emergency message (level 0) with args
[ 2.839481] rust_print: Alert message (level 1) with args
[ 2.839803] rust_print: Critical message (level 2) with args
[ 2.840127] rust_print: Error message (level 3) with args
[ 2.840456] rust_print: Warning message (level 4) with args
[ 2.840587] rust_print: Notice message (level 5) with args
[ 2.841027] rust_print: Info message (level 6) with args
[ 2.841338] rust_print: A line that is continued with args
[ 2.841794] rust_print: 1
[ 2.842115] rust_print: hello, world
[ 2.842667] rust_print: [../samples/rust/rust_print.rs:34] c hello, world
6.2 自己编写一个rust的helloworld驱动
线进入samples/rust目录编写一个rust的驱动rust_hello.rs
// SPDX-License-Identifier: GPL-2.0
//! Rust minimal sample.use kernel::prelude::*;module! {type: RustHelloWorld,name: rust_helloworld,author: whocare,description: hello world module in rust,license: GPL,
}struct RustHelloWorld {}impl kernel::Module for RustHelloWorld {//fn init(_name: static CStr, _module: static ThisModule) - ResultSelf {fn init(_module: static ThisModule) - ResultSelf {pr_info!(Hello World from Rust module);Ok(RustHelloWorld {})}
}然后在Makefile文件中添加
obj-y rust_hello.o最后再次编译和运行可以看到下面的输出
[ 2.843635] rust_helloworld: Hello World from Rust module
