以 ** 一加6T ** 为例
@skr-niao 的一加6T的成品(Manjaro)：Releases · silime/plasma-mobile · GitHub
对于mix3： How to Install Arch Linux on Xiaomi Mi MIX 3 (based on EDK2) (xperseus.dev)
效果：
1 编译内核
sdm845成品：
Releases · silime/kernel-builder (github.com)
来自 @skr-niao
1.1 安装相关依赖
对于Ubuntu 22.04 LTS:
sudo apt install build-essential openssl pkg-config libssl-dev libncurses5-dev pkg-config minizip libelf-dev flex bison libc6-dev libidn11-dev rsync bc liblz4-tool
sudo apt install gcc-aarch64-linux-gnu dpkg-dev dpkg git
1.2 克隆内核源码
你可以在“-b”参数后选择其他分支
注：带有mi 8(dipper)支持的内核源码https://gitlab.com/mainline-xiaomi-dipper/linux
mkdir ~/workspace
cd ~/workspace
git clone --depth=1 https://gitlab.com/sdm845-mainline/linux.git -b sdm845/5.18-release
# note: for mi 8
# git clone --depth=1 https://gitlab.com/mainline-xiaomi-dipper/linux.git -b 5.18-xiaomi-dipper
可用分支可在gitlab网页查看
1.3 为一加6T添加tfa98xx驱动（弃用）
备注：在内核源码（ Files · sdm845/5.19-release · Qualcomm Snapdragon 845 Mainline / Linux · GitLab）中，已经加入了来自下游的tfa98xx驱动，不需要额外手动添加，如果你使用较新的分支，请跳过此步骤
详见：
ASoC: codecs: add support for TFA98xx based on downstream (bc7a7e04) · Commits · Qualcomm Snapdragon 845 Mainline / Linux · GitLab
摘要

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j$(nproc)
生成deb包供Debian系得GNU/Linux使用
make -j$(nproc) ARCH=arm64 KBUILD_DEBARCH=arm64 KDEB_CHANGELOG_DIST=mobile CROSS_COMPILE=aarch64-linux-gnu- deb-pkg
# This will generate several deb files in ../
2 制作rootfs
2.1 下载
对于Archlinux，从http://os.archlinuxarm.org/os/ArchLinuxARM-aarch64-latest.tar.gz下载
cd ~/workspace
wget http://os.archlinuxarm.org/os/ArchLinuxARM-aarch64-latest.tar.gz
对于Ubuntu，从 Index of /ubuntu-base选择自己想要的版本
2.2 制作
2.2.1 进入chroot
sudo apt install qemu-user-static
dd if=/dev/zero of=archlinux.img bs=1G count=6
mkfs.ext4 archlinux.img
mkdir arch
sudo mount archlinux.img arch
cd arch
sudo tar -xpvf ../ArchLinuxARM-aarch64-latest.tar.gz
cd ..
sudo mount --bind /dev arch/dev
sudo mount -t devpts devpts arch/dev/pts -o gid=5,mode=620
sudo mount -t proc proc arch/proc
sudo mount -t sysfs sysfs arch/sys
sudo mount -t tmpfs tmpfs arch/run
sudo rm -rf arch/etc/resolv.conf && sudo cp /etc/resolv.conf arch/etc/
sudo chroot arch
2.2.2 初始化pacman keyring
pacman-key --init
pacman-key --populate archlinuxarm
2.2.3 换源（可选）
详见 archlinuxarm | 镜像站使用帮助 | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror
pacman -Syyu
# upgrade
2.2.4 卸载旧的内核和firmware
pacman -Q | grep -i linux
pacman -R linux-aarch64 linux-firmware linux-firmware-whence
exit
# exit chroot environment
2.2.5 安装新的内核和firmware
先退出chroot环境
然后：
cd ~/workspace/linux
sudo make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_MOD_PATH=~/workspace/arch modules_install
sudo make ARCH=arm64 INSTALL_PATH=~/workspace/arch/boot install
如果是debian系也可以直接用dpkg安装deb
下载为一加6和一加6T定制的firmware（来自mobian源和Debian源）（ Index of /pool/non-free/f/ (mobian.org)）（ Index of /debian/pool/non-free/f/firmware-nonfree/ | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror）
https://stor.classfun.cn:4443/s/0Nsa
对于其它设备，如果有PostmarketOS/Mobian支持，可以从中直接提取，如果没有，请自己准备
解压得到三个deb文件，复制进rootfs，虽然是arch，但也可以用dpkg安装firmware
警告
不要使用dpkg安装别的任何软件包！！！！切记切记！！
sudo cp -r *.deb ~/workspace/arch/root/
如果要启用一加6T的声音，下载(GitHub - J0SH1X/tfa98xx)中的 tfa98xx.cnt
复制入rootfs
sudo cp tfa98xx.cnt ~/workspace/arch/root/
重新进入chroot环境,安装firmware，生成initial ramdisk
详见 mkinitcpio - ArchWiki (archlinux.org)
sudo chroot ~/workspace/arch
cd ~
pacman -S dpkg
dpkg -i *.deb
mv ~/tfa98xx.cnt /usr/lib/firmware/
ldconfig
修改/etc/mkinitcpio.conf
nano /etc/mkinitcpio.conf
找到
# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image. This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()
在BINARIES=()填入xxxx_zap.mbn/ipa_fws.mbn的路径
这两个固件的来源一般是手机提取并放在特殊的位置加载（具体由dts/dtsi指定）
对于fajita，改为：
BINARIES=(/usr/lib/firmware/qcom/sdm845/oneplus6/a630_zap.mbn /usr/lib/firmware/qcom/sdm845/oneplus6/ipa_fws.mbn)
ls /usr/lib/modules
# get kernel version
mkinitcpio --generate /boot/initrd.img-5.18.0-sdm845-00109-gf7ad1e5036bb-dirty --kernel 5.18.0-sdm845-00109-gf7ad1e5036bb-dirty

2.2.7 有关LTE和一加6T的声音支持
2.2.7.1 修改Modemmanager
重新编译ModemManager，开启plugin_qcom_soc,并安装
su alarm
mkdir ~/modemmanager
cd ~/modemmanager
nano PKGBUILD
将 PKGBUILD - modemmanager (aarch64) | Package Files | Arch Linux ARM 中的内容复制进PKGBUILD
然后进行以下修改
将arch=(x86_64)改为arch=(x86_64 aarch64)
将-D plugin_qcom_soc=disabled一行删除
10c10
< arch=(x86_64)
---
> arch=(x86_64 aarch64)
35d34
< -D plugin_qcom_soc=disabled
makepkg -rsi
# compile and install
cd ..
sudo rm -rf ~/modemmanager
exit
systemctl enable ModemManager
2.2.7.2 alsa-ucm-conf的配置
在chroot环境中， 将alsa-ucm-conf改为定制版本
Releases · silime/kernel-builder (github.com)
用pacman -U安装此处成品
2.2.7.3 确保tfa98xx模块加载
echo 'snd-soc-tfa98xx' > /etc/modules-load.d/snd-soc-tfa98xx.conf
2.2.7.4 通话音频
详见： postmarketOS / q6voiced · GitLab
安装此处的q6voiced： Release q6voice · silime/kernel-builder (github.com)
pacman -U xxx.pkg.tar.zst
systemctl enable q6voiced
2.2.8 打包
先清理，在chroot环境中
pacman -Scc
# pacman
su alarm # switch to alarm
# clean bash history for alarm
cat /dev/null > ~/.bash_history && history -c && exit
# clean bash history for root
cat /dev/null > ~/.bash_history && history -c
退出chroot环境
exit
解除挂载
cd ~/workspace
sudo umount ~/workspace/arch/run
sudo umount ~/workspace/arch/sys
sudo umount ~/workspace/arch/proc
sudo umount ~/workspace/arch/dev/pts
sudo umount ~/workspace/arch/dev
用tar打包
cd ~/workspace/arch
sudo tar -czvf ~/workspace/arch.tar.gz *
# This will generate arch.tar.gz
3 安装到手机
3.1 刷入twrp和Magisk
解锁、刷TWRP、刷magisk
3.2 分区、格式化分区
连接手机、电脑，手机进twrp
将parted复制到手机储存
电脑输入：
adb shell
然后输入：
cp /sdcard/parted /sbin/ && chmod 755 /sbin/parted
umount /data && umount /sdcard
parted /dev/block/sda
输入p查看当前分区情况
p
对于一加6T，可这样分区：
压缩分区17
resizepart 17
# input 61GB
mkpart esp fat32 61GB 62GB
mkpart arch ext4 62GB 125GB
set 18 esp on
q
# exit parted
再次重启到twrp，格式化各分区
adb shell
mkfs.fat -F32 -s1 /dev/block/by-name/esp
mke2fs -t ext4 /dev/block/by-name/arch
mke2fs -t ext4 /dev/block/by-name/userdata
3.3 获取UUID
重启到Android，在termux或adb shell输入
su
blkid /dev/block/by-name/arch
记下UUID值
3.4 准备grub配置文件
下载grub
esp.zip (78.5 KB)
boot.tar(1).gz (6.7 MB)
将boot.tar.gz中grub.cfg的uuid全部改为步骤3.3中得到的
替换所有这种字符
3.5 解压rootfs
将arch.tar.gz复制到手机内部存储
建议使用termux操作
pkg update
pkg install tsu
tsu
# root permission needed
cd ~
mkdir arch
mount /dev/block/by-name/arch ~/arch
cd ~/arch
tar -xpvf /sdcard/arch.tar.gz
# extract
3.6 安装grub
tsu
cd ~
mkdir esp
mount /dev/block/by-name/esp esp
mkdir esp/EFI
将esp.zip中这两个文件夹复制到~/esp/EFI/
# /dev/block/by-name/arch has been mounted!
cd ~/arch/boot && ls
将boot.tar.gz内两个文件夹复制进~/arch/boot
3.7 获取、添加dtb
对于一加6T，还需要将这两个dtb复制到~/arch/boot
注：对于一加6（T）不要使用内核编译生成的dtb
见arch/arm64/boot/dts/qcom/sdm845-oneplus-common.dtsi,将不会有显示
对于其它设备，请获取合适的dtb
arch/arm64/boot/dts/qcom/sdm845-oneplus-common.dtsi部分内容（点击展开）
/delete-node/ &rmtfs_mem;
/ {
aliases {
serial0 = &uart9;
hsuart0 = &uart6;
};
chosen {
stdout-path = "serial0:115200n8"; /*line 30 in dtsi*/
};
volume-keys {
compatible = "gpio-keys";
label = "Volume keys";
autorepeat;
3.7.1 dtb的获取
下载适用自己设备的postmarketOS的boot.img.xz，解压得到img文件
使用 extract-dtb · PyPI
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple extract-dtb
extract-dtb 20220608-1408-postmarketOS-v22.06-phosh-18-oneplus-fajita-boot.img -o .
# use your own img
# will generate something like 01_dtbdump_,OnePlus_6T.dtb
ls
mv 01_dtbdump_,OnePlus_6T.dtb sdm845-oneplus-fajita.dtb
3.7.2 修改dtb，使得可能支持USB otg
提示：似乎会导致USB网络不可用！！
#for Ubuntu 22.04 LTS
sudo apt install device-tree-compiler -y
dtc -I dtb -O dts -o temp.dts xxx.dtb
# e.g. dtc -I dtb -O dts -o temp.dts sdm845-oneplus-fajita.dtb
nano temp.dts
查找dr_mode
找到类似：
dwc3@a600000 {
compatible = "snps,dwc3";
reg = <0x00 0xa600000 0x00 0xcd00>;
interrupts = <0x00 0x85 0x04>;
iommus = <0x25 0x740 0x00>;
snps,dis_u2_susphy_quirk;
snps,dis_enblslpm_quirk;
phys = <0xb8>;
phy-names = "usb2-phy";
dr_mode = "peripheral";
maximum-speed = "high-speed";
};
将peripheral改为host 此时生成的dtb将支持otg，但要外界供电，为了USB主动供电，需要进一步修改,但会导致充电失效
将charger@1000那段删除
pmic@2 {
compatible = "qcom,pmi8998\0qcom,spmi-pmic";
reg = <0x02 0x00>;
#address-cells = <0x01>;
#size-cells = <0x00>;
charger@1000 {
compatible = "qcom,pmi8998-charger";
reg = <0x1000>;
interrupts = <0x02 0x13 0x04 0x03 0x02 0x>
interrupt-names = "usb-plugin\0bat-ov\0wd>
io-channels = <0xdd 0x03 0xdd 0x04>;
io-channel-names = "usbin_i\0usbin_v";
status = "okay";
monitored-battery = <0xde>;
};
gpios@c000 {
compatible = "qcom,pmi8998-gpio\0qcom,spm>
reg = <0xc000>;
gpio-controller;
gpio-ranges = <0xdf 0x00 0x00 0x0e>;
#gpio-cells = <0x02>;
interrupt-controller;
#interrupt-cells = <0x02>;
phandle = <0xdf>;
};
生成新的dtb
dtc -I dts -O dtb -o xxx-host.dtb temp.dts
# e.g. dtc -I dts -O dtb -o sdm845-oneplus-fajita-host.dtb temp.dts
# generate modyfied dtb
复制好dtb，你的usb otg应该就有可能工作
4 刷入UEFI
进入bootloader
对于非a/b
临时启动uefi
fastboot boot boot-xxx.img
刷入到当前boot分区
fastboot flash boot boot-xxx.img
刷入到recovery分区
fastboot flash recovery boot-xxx.img
其他a/b
临时启动uefi
fastboot boot boot-xxx.img
刷入a或b
fastboot flash boot_a boot-xxx.img
或
fastboot flash boot_b boot-xxx.img
可用
fastboot set_active a
或
fastboot set_active b
切换a/b
5 Enjoy！
恭喜你！你已经成功在你的手机上安装Archlinux！！希望你能有所收获！！ 
5.1 通过USB网络连接ssh
非常有用的功能，比如你发现无法使用WiFi（比如你忘记安装qrtr/rmtfs一类软件包），这将成为一个很好补救措施
将手机插入电脑，在电脑命令行输入
ssh alarm@10.15.19.82
# ssh allows you to control your phone!

6 可能需要的修复/调整
6.1 修复sdm845关机crashdump
如果关机可能会出现crashdump
特别感谢 @skr-niao 大佬
sudo nano /etc/systemd/system/shutdown-modem.service
填入
[Unit]
Description=Poweroff modem remoteproc to prevent wlan fw crash
DefaultDependencies=no
Before=shutdown.target
[Service]
Type=oneshot
# remoteproc2 is always the modem on SDM845
ExecStart=echo stop | tee /sys/class/remoteproc/remoteproc*/state
[Install]
WantedBy=shutdown.target
启用服务
sudo systemctl enable shutdown-modem.service
# sudo systemctl start shutdown-modem.service
它会在关机前关闭modem remoteproc
