lab3:基于VS Code的Linux内核调试环境搭建

1.安装相关依赖包

sudo snap install --classic code
sudo apt install build-essential
sudo apt install qemu

2.安装VSCode

sudo snap install --classic code

3.安装内核

sudo apt install axel
axel -n 20 https://mirrors.edge.kernel.org/pub/linux/kernel/v5.x/linux-5.4.34.tar.xz
xz -d linux-5.4.34.tar.xz
tar -xvf linux-5.4.34.tar
cd linux-5.4.34

4.进行内核调试

$ make defconfig # Default configuration is based on 'x86_64_defconfig'
$ make menuconfig
# 打开debug相关选项
Kernel hacking  --->
    Compile-time checks and compiler options  --->
        [*] Compile the kernel with debug info
        [*]   Provide GDB scripts for kernel debugging
 [*] Kernel debugging
# 关闭KASLR，否则会导致打断点失败
