8 通过gdb调试内核和模块
11 Kgdb内核调试器、QEMU等虚拟机管理程序或基于JTAG的硬件接口，支持在运行时使用gdb
14 此教程基于QEMU/KVM虚拟机，但文中示例也适用于其他gdb stub。
20 - gdb 7.2+ (推荐版本: 7.4+) 且开启python支持 (通常发行版上都已支持)
37 - 启用QEMU/KVM的gdb stub，可以通过如下方式实现
47 - 启动gdb：gdb vmlinux
49 注意：某些发行版可能会将gdb脚本的自动加载限制在已知的安全目录中。
50 如果gdb报告拒绝加载vmlinux-gdb.py（相关命令找不到），请将::
54 添加到~/.gdbinit。更多详细信息，请参阅gdb帮助信息。

18 - gdb 7.2+ (recommended: 7.4+) with python support enabled (typically true
42 - Build the gdb scripts (required on kernels v5.1 and above)::
46 - Enable the gdb stub of QEMU/KVM, either
57 - Start gdb: gdb vmlinux
59 Note: Some distros may restrict auto-loading of gdb scripts to known safe
