Ampere ARM Server 内核版本更新

本篇记录 Ampere ARM Server 服务器上，升级内核版本或部分驱动的方法。

安装编译依赖库

sudo  apt-get install build-essential kernel-package libncurses5-dev libncurses-dev
sudo apt-get install gcc make bison flex libssl-dev

升级内核

##<1>. 编译内容

下载内核

选择国内内核镜像网站,下载对应版本内核。

使用运行版本的 config 文件

先清除前面编译残留文件,使用 ARM Server 运行的 config 文件编译内核;

$ make mrproper 
$ cp /boot/config-5.15.0-73-generic ./.config
$ make menuconfig

修改配置项

make menuconfig 选择

 Kernel hacking —> Compile-time checks and compiler options —>(1024)Warn for stack frames larger than //将1024改为2048
 Kernel hacking —> Compile-time checks and compiler options —> [ ]   Generate BTF typeinfo //选中该选项

去除 system_trusted 内容

vim .config
#
# Certificates for signature checking
#
CONFIG_SYSTEM_TRUSTED_KEYRING=y
CONFIG_SYSTEM_TRUSTED_KEYS=""       ## 清空 keys 内容
CONFIG_SYSTEM_EXTRA_CERTIFICATE=y
CONFIG_SYSTEM_EXTRA_CERTIFICATE_SIZE=4096
CONFIG_SECONDARY_TRUSTED_KEYRING=y
CONFIG_SYSTEM_BLACKLIST_KEYRING=y
CONFIG_SYSTEM_BLACKLIST_HASH_LIST=""
CONFIG_SYSTEM_REVOCATION_LIST=y
CONFIG_SYSTEM_REVOCATION_KEYS=""   ## 清空 keys 内容 
# end of Certificates for signature checking

安装内核编译支持库libssl-dev

sudo apt-get install libssl-dev

编译内核

make menuconfig 开启 android 相关支持模块, binder ashmem模块支持,
并修改 Makefile 文件中内核版本号。

make -j 64

<2>. 更新内核版本

以下指令在 /usr/src/linux-5.15.23 内核源码根目录.

2.1> 安装内核

将生成的Image镜像文件复制到目录下

cp arch/arm64/boot/Image /boot/vmliuz-5.15.23

将源代码目录下的System.map复制到/boot目录下：

cp System.map /boot/System.map-5.15.23

将源代码目录下的.config复制到/boot/目录下：

cp .config /boot/config-5.15.23

2.2> 安装模块

更新 grub 后已经把 grub 缺省为当前的系统版本,重启系统后就自动进入 5.15.23 系统。

升级驱动

如果仅更新部分 *.ko 内容，可以指定安装位置，然后把模块更新到系统中。内核编译过程与升级内核部分
描述的方法相同，make menuconfig 中选择相关驱动模块,编译出 *.ko 文件,把此模块拷贝至对应的文件目录下，
记着执行 depmod -a 刷新驱动的依赖关系。通过 modinfo 查看模块是否为更新后的驱动模块。
