ARM64 FT2000+ openEuler release 22.03 LTS 手动编译自带的内核 linux-5.10.0-60.18.0.50.oe2203.aarch64

安装内核源码

yum install kernel-source

源码复制到内存盘，提高构建速度

rsync -avr -P /usr/src/linux-5.10.0-60.18.0.50.oe2203.aarch64 /tmp/

复制原始config文件

 cp /boot/config-5.10.0-60.18.0.50.oe2203.aarch64 /tmp/linux-5.10.0-60.18.0.50.oe2203.aarch64/.config

安装编译工具、库

yum install -y gcc make elfutils-libelf-devel dwarves

开始编译

cd /tmp/linux-5.10.0-60.18.0.50.oe2203.aarch64/
make oldconfig
make -j64

完成

编译内核模块

make modules -j64

安装新内核

make modules_install
make install

重启不能引导。。。
