android-kernel-compile

1.设置环境变量

设置这个环境变量是因为Repo在使用过程中会访问Google更新自己，容易被墙

export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'

2.初始化仓库

（1）manifest.git

原版链接

repo init -u https://android.googlesource.com/kernel/manifest
mv <kernel_manifest.xml> .repo/manifests
repo init -m manifest.xml
repo sync

使用清华源，不指定分支会报错，我也不知道为什么,不过没什么影响

repo init -u https://mirrors.ustc.edu.cn/aosp/kernel/manifest.git -b android-gs-pantah-5.10-android13-qpr2

（2）下载manifest.xml

然后找到对应的manifest.xml，放在.repo/manifests目录下 https://source.android.com/docs/core/architecture/kernel/gki-android13-5_10-release-builds?hl=zh-cn 如果找不到对应版本的话，可以在https://ci.android.com/builds/submitted/9750494/kernel_aarch64/latest?hl=zh-cn（9750494换成和你手机一样的编号，如下我的设备是9598324)

adb shell
panther:/ $ uname -a
Linux localhost 5.10.149-android13-4-00002-gca169caca7bb-ab9598324 #1 SMP PREEMPT Mon Feb 13 12:48:28 UTC 2023 aarch64 Toybox
panther:/ $

（3）更改fetch链接和分支

找到manifest_10208116.xml 后，拷贝到.repo/manifests目录下，需要修改两处 1.fetch="https://android.googlesource.com/"改为fetch="https://mirrors.tuna.tsinghua.edu.cn/git/AOSP" 2.project path="common"中的upstream="android13-5.10-2023-02"改为upstream="deprecated/android13-5.10-2023-02"（分支被遗弃，较新的分支不需要这一步） 具体有没有废弃可以在https://android.googlesource.com/kernel/common/+refs上查看

3.同步代码

repo sync -j12

4.编译

LTO=thin BUILD_CONFIG=common/build.config.gki.aarch64 build/build.sh

编译结果存放在/home/showfaker/kernel/out/android13-5.10/dist下，pixel7使用的是boot-lz4.img

5.编译kernelSU

curl -LSs "https://raw.githubusercontent.com/tiann/KernelSU/main/kernel/setup.sh" | bash -

然后再次在根目录下运行编译命令

LTO=thin BUILD_CONFIG=common/build.config.gki.aarch64 build/build.sh

6.刷机

adb reboot bootloader
fastboot flash boot .\boot-lz4.img

然后开机启动，打开kernelSU的管理APP，可以看到已经可以正常工作 tips：如果遇到循环启动那就是刷机失败了，建议刷回原版镜像重试
