为红米note4x移植debian/ubuntu

sudo apt install  gcc-aarch64-linux-gnu kernel-package  simg2img img2simg mkbootimg bison flex gcc-aarch64-linux-gnu pkg-config libncurses-dev libssl-dev unzip git kmod cpio bsdmainutils rsync

具体参考以下两份教程

编译教程.md

mido.md

注意：

debian内核不能压缩，需要在make menuconfig时，将此项设置None

固件加载

在https://gitlab.com/postmarketOS/pmaports/-/blob/master/device/community的firmware开头的目录下找到APKBUILD文件，观察文件内容，手动下载固件并且导入rootfs.img的/lib/firmware目录下

提前在chroot进入rootfs.img时安装wireless-tool 和 swpa_supplicant

小技巧：

关闭屏幕背光（必须在root用户下执行）

echo 1 > /sys/class/backlight/backlight/bl_power

扩容

resize2fs $(df / | awk '$NF=="/"{print $1}')

查看电池电量

upower -e查看设备

upower -i 任意一个路径

例如

root@hu:~# upower -e
/org/freedesktop/UPower/devices/battery_smb1360_battery
/org/freedesktop/UPower/devices/DisplayDevice
root@hu:~# upower -i /org/freedesktop/UPower/devices/DisplayDevice

查看电池电量

upower -i /org/freedesktop/UPower/devices/battery_qcom_battery

开启串口调试

内核配置需要打开g_serial

以模块的方式编译

已经安装了原内核的系统也可直接安装开启了虚拟串口的内核

单独使用

启用g_serial模块

sudo modprobe g_serial

开启串口终端，最好以service的形式启用

sudo agetty -L ttyGS0 115200 vt100

[Unit]
Description=Serial Console on ttyGS0
After=multi-user.target

[Service]
ExecStart=/sbin/agetty -L ttyGS0 115200 vt100
Restart=always
RestartSec=3

[Install]
WantedBy=multi-user.target

适用于没有wifi的时候调试

串口一般用于没有wifi时调试系统，所以可以写一个脚本，判断是否成功链接wifi，如果有wifi，就不启动串口，因为会占用usb接口，没有otg功能

判断是否有wifi脚本

root@hu:~# cat /home/open_serial.sh 
#!/bin/bash
sleep 15
# 检测网络连接
if ping -q -c 1 -W 1 223.5.5.5  >/dev/null; then
    echo "网络连接成功"
else
    echo "网络连接失败"
    # 加载g_serial模块
    modprobe g_serial
    # 运行agetty命令
    agetty -L ttyGS0 115200 vt100
fi

调用该脚本的service服务文件内容

root@hu:~# cat /etc/systemd/system/open_serial.service 
[Unit]
Description=Check Network Connectivity and Load g_serial Module if not Connected
After=multi-user.target

[Service]
Type=simple
ExecStart=/bin/bash -c '/home/open_serial.sh'
Restart=always

[Install]
WantedBy=multi-user.target

之后启用服务

sudo systemctl enable open_serial

关闭wiif后重启设备查看是否生效

GPU驱动

ubutnu直接添加mesa驱动的ppa源

sudo add-apt-repository ppa:kisak/kisak-mesa

或者手动添加源nano /etc/apt/sources.list.d/mesa.list

deb https://ppa.launchpadcontent.net/kisak/kisak-mesa/ubuntu jammy main
deb-src https://ppa.launchpadcontent.net/kisak/kisak-mesa/ubuntu jammy main

然后安装相关驱动就行

apt install libclang-common-15-dev libclang-cpp15 libclang-rt-15-dev:arm64 libclc-15 libclc-15-dev libdrm-amdgpu1:arm64 libdrm-common libdrm-nouveau2:arm64 libdrm-radeon1:arm64 libdrm2:arm64 libegl-mesa0:arm64 libegl1-mesa-dev:arm64 libgbm1:arm64 libgl1-mesa-dev:arm64 libgl1-mesa-dri:arm64 libglapi-mesa:arm64 libgles2-mesa-dev:arm64 libglx-mesa0:arm64 libllvm15:arm64 libosmesa6:arm64 mesa-libgallium:arm64 mesa-opencl-icd:arm64 mesa-va-drivers:arm64 mesa-vdpau-drivers:arm64 mesa-vulkan-drivers:arm64 mesa-utils libgl1-mesa-dev libgles2-mesa-dev libegl1-mesa-dev opencl-headers ocl-icd-libopencl1 ocl-icd-opencl-dev glmark2 libclang-common-15-dev libclang-cpp15 libclang-rt-15-dev libclc-15 libdrm-common

debian的话需要一些野鸡办法，改os-release假装自己是ubuntu

比如debian12就修改/etc/os-release成

NAME="Ubuntu"
VERSION="22.04.3 LTS (Jammy Jellyfish)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 22.04.3 LTS"
VERSION_ID="22.04"
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=jammy
UBUNTU_CODENAME=jammy

常用软件包

sudo apt install language-pack-en-base ssh net-tools ethtool ifupdown iputils-ping htop vim kmod network-manager make gcc g++ git nano fdisk usbutils initrmfs-tools initramfs-tools xinit xinput x11-xserver-utils xserver-xorg-input-evdev xserver-xorg-input-libinput xserver-xorg-legacy xserver-xorg-video-fbdev fonts-noto-cjk bash-completion

时间同步
