背景

在windows下使用VScode编辑器，源码存放在远程Linux服务器中，编译也在Linux中进行，windows下只编辑+查看。

1 ssh远程登录

先安装ssh插件：Remote-ssh，点击右下角箭头，输入账号密码后ssh登录。注意：首次连接极大可能出现连接失败，报timeout的错误，修改下ssh的timeout参数即可

2 ssh免密码登录

把ssh的公钥和私钥放在C:\Users\用户名.ssh下也可以创建config文件，为ssh起一个别名，这样就不用记ip地址了。

Linux远程需要安装的插件

CmakeCmake-toolsClang-FormatRainbow BracketsTrailing SpacesInclude AutocompletePylance 4 Linux内核源码显示过滤

因为Linux本身就是可裁剪的，源码可能包含大量的无关内容，比如设备树或defconfig文件，使用显示过滤，直接过滤掉arch/arm/、arch/arm64/boot等无关文件夹，需要啥，显示啥，清爽无比。

5 Linux 源码宏定义 5.1 创建c_cpp_properties.json，补充宏

Linux本身就是支持裁剪的，大部分源码都使用宏定义进行编译控制，如：

#ifdef CONFIG_MMU funA() #else funB() #endif

而Linux的宏很多都是在arch/arm64/configs/*defconfig文件指定的（实际上每次编译make xxx_defconfig，就是把defconfig文件按照Kconfig的语法重新组织，生成.config文件，再生成auto_config，下次make时会使用auto_config里面的宏）同样地，在.vscode/c_cpp_properties.json添加内容：

5.2 将defconfig文件中的定义复制到c_cpp_properties.json Ctrl+A将defconfig中的全部信息都复制粘贴到c_cpp_properties.json的"defines":后面。Ctrl+H打开“替换”，选择“正则表达式” 删除掉"#"开头，如：# CONFIG_COMPILE_TEST is not set^#.* 替换为空其中：^是行开头搜索，#是关键字，.是选择后一个字符，*是通配符直接点击替换，啥都不用输入。删除"=“xxx” "，如：CONFIG_DEFAULT_TCP_CONG=“cubic” 变成 CONFIG_DEFAULT_TCP_CONG=.*" 与 =.* 都替换为空

直接点击替换，啥都不用输入。

为前后加上""：CONFIG_TARGET_XJ3变成"CONFIG_TARGET_XJ3 "查找：^C；替换为："C

后面的没办法，只能

$替换为 ",

然后把多余的删掉

删除空白行：^\s*\n

其中：^匹配字符串开始；\s匹配空白字符；*匹配前面的子表达式零次或多次；\n匹配换行符

删除掉"=y"：直接"=y"替换为空删除掉"既带有CONFIG_，又带有"结尾的" (?=.*CONFIG_)(?=.*").* “既带有CONFIG_，又带有=的” (?=.CONFIG_)(?=.=).* 6 Linux 代码自动规范

代码写完后，不符合代码规范？arc lint报错？手动改太慢了？下载插件：Clang-Format 在kernel目录下创建：.clang-format，复制粘贴如下内容：

下次写代码，直接用Clang-Format格式化代码即可。
