编译特定模块

配置Rust For Linux

• make LLVM=1 rustavailable (参考Documentation/rust/quick-start.rst)
• 确保Rust相关的Depends条件是否符合

• make menuconfig 开启Rust

• make LLVM=1 -j 128
• 添加Rust-project

1. make LLVM=1 rust-analyzer
2. add rust-project.json to the rust-analyzer.linkedProjects

"rust-analyzer.linkedProjects": [
        "rust-project.json",
    ]

配置Vscode环境开发Linux kernel

• clangd 支持linux kernel跳转

# 生成compile_commands.json文件
python3 scripts/clang-tools/gen_compile_commands.py

# 安装clangd，并配置
{
    "clangd.path": "/usr/bin/clangd-14",
    "clangd.arguments": [
        "--compile-commands-dir=${workspaceFolder}"
    ]
}

• 使用code-lldb debug linux kernel

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: <https://go.microsoft.com/fwlink/?linkid=830387>
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Remote attach",
            "type": "lldb",
            "request": "custom",
            "targetCreateCommands": ["target create ${workspaceFolder}/vmlinux"],
            "processCreateCommands": ["gdb-remote localhost:1234"]
        }
    ]
}

通过Qemu Debug最新的内核

• 通过create-image.sh创建rootfs
