config 配置

make menuconfig

比如开启BTF
//选中kernel hacking --> Compile-time checks and compiler option -->Generate BTF

保存完成后重新将源码打包成xz 文件

sudo yum groupinstall "Development Tools"
sudo yum install ncurses-devel bc kmod openssl-devel elfutils-libelf-devel rpm-build
make ARCH=arm64 defconfig
make ARCH=arm64 menuconfig

rpm 编译配置

%define __spec_install_post %{nil}
%define debug_package %{nil}
%define __os_install_post %{_dbpath}/brp-compress
