简介 / Introduction

中文:
该 repo 基于 LineageOS/android_kernel_qcom_sm8250，结合了 Strawing 的仓库 和 UtsavBalar1231 的仓库，以及原本的 LineageOS/android_kernel_xiaomi_sm8250。一些提交同样来源于开源社区中的其他开发者。

English:
This repository is based on LineageOS/android_kernel_qcom_sm8250, incorporating Strawing's repository and UtsavBalar1231's repository, as well as the original LineageOS/android_kernel_xiaomi_sm8250. Some commits also originate from other developers in the open-source community.

特性 / Features

中文:
本内核支持 ReSukiSU & SuSFS。请自行安装 ReSukiSU 的管理器。NoKernelSU 版本支持应用 Magisk 和 APatch(及他们的分支)。

Release 里的编译好的内核成品由 android17-aptusitu 分支编译，应当能在原版 MIUI/HyperOS 和第三方的基于 AOSP 的各种 Android11-17 的 ROM 上使用。欢迎大家尝试并反馈(提 Issue 或 Pull Requests)! 酷友们到 这个帖子 讨论或反馈，也可以加入 QQ 群，或者给我私信反馈!

以下是一些具体的功能:

1. F2FS 开启了 realtime discard 以更好地 TRIM 闪存
2. 支持 EROFS
3. zRAM 支持 LZO、LZ4、LZ4HC、ZSTD 等压缩算法，开启了 ZRAM_WRITEBACK，升级了 LZ4 和 ZSTD
4. 向后移植 5.15 BPF 和 clone3(支持安卓 16/17)
5. 引入 LE9EC 以优化内存
6. 向后移植 5.10 的 Binder，MIUI 构建引入来自 xaga 的 millet，AOSP 构建引入 Re:Kernel
7. 修复电量卡在 1% 的问题，并且支持解容
8. 集成 BBG(Baseband-guard)

English:
This kernel supports ReSukiSU & SuSFS.
Please install the ReSukiSU Manager by yourself.
The NoKernelSU version supports Magisk and APatch (and their forks).

The prebuilt kernel in the Release section is compiled from the android17-aptusitu branch, and should work on stock MIUI/HyperOS as well as third-party AOSP-based ROMs for Android 11–17.
Feedback is welcome (via Issues or Pull Requests)! Coolapk users can join the discussion in this post, you can also join my QQ group, or send me private feedback.

Below are some of the key features:

1. F2FS with realtime discard enabled for improved flash TRIM behavior
2. Support for EROFS
3. zRAM with support for multiple compression algorithms, including LZO, LZ4, LZ4HC, and ZSTD, enabled ZRAM_WRITEBACK, upgraded LZ4 and ZSTD
4. Backported BPF from Linux 5.15 and clone3 (Android 16/17 compatible)
5. Introduced LE9EC to optimize memory
6. Backported Binder from 5.10; MIUI builds incorporate millet from xaga, while AOSP builds incorporate Re:Kernel
7. Fixes the issue where the battery percentage gets stuck at 1%, and supports recognizing higher-capacity replacement batteries
8. Integrate BBG(Baseband-guard)

构建方法 / Build Instructions

快速构建 / Quick Build

中文:

1. fork 本仓库(别忘了点个 Star~)
2. 进入 Actions
3. 如果你要为所有支持的设备编译内核，找到 Build All Devices Kernel (Matrix Parallel + Release)，点击 Run workflow
4. 如果你要为单个设备编译内核，找到 Build Kernel， 点击 Run workflow 并选择必要内容

English:

1. Fork this repo (don’t forget to leave a Star~)
2. Go to Actions
3. If you want to compile the kernel for all supported devices, find Build All Devices Kernel (Matrix Parallel + Release) and click Run workflow
4. If you want to compile the kernel for a single device, find Build Kernel, click Run workflow, and select the necessary options

手动构建 / Manual Build

中文:

1. 准备基本构建环境。
   需要常用工具链 git、make、curl、bison、flex、zip 等，以及一些软件包。

   • 在 Debian/Ubuntu:

   sudo apt install build-essential git curl wget bison flex zip bc cpio libssl-dev ccache tar
   

   还需要 python (仅有 python3 不够)，可安装:

   sudo apt install python-is-python3
   

   • 在 RHEL/RPM 系统:

   sudo yum groupinstall 'Development Tools'
   sudo yum install wget bc openssl-devel ccache tar
   

   注意：build.sh 中启用了 ccache，路径是 $HOME/.cache/ccache_mikernel。可修改或删除。

2. 下载 ZyC-Clang v16 工具链:

   mkdir zyc-clang
   cd zyc-clang
   wget https://github.com/ZyCromerZ/Clang/releases/download/16.0.6-20260807-release/Clang-16.0.6-20260807.tar.gz
   tar -zxvf Clang-16.0.6-20260807.tar.gz
   cd ..
   

3. 构建:

   • 不使用 KernelSU:

     bash build_kernel.sh TARGET_DEVICE TARGET_OS(省略为全部编译)
     

   • 使用 KernelSU:

     bash build_kernel.sh TARGET_DEVICE ksu TARGET_OS(省略为全部编译)
     

   示例:

   • lmi (Redmi K30 Pro/POCO F2 Pro) 不使用 KernelSU，为 MIUI 编译:

     bash build_kernel.sh lmi miui
     

   • cmi (Xiaomi 10 Pro) 使用 KernelSU，为 MIUI 编译:

     bash build_kernel.sh cmi ksu miui
     

   • umi (Xiaomi 10) 使用 KernelSU，为 AOSP 和 MIUI 编译:

     bash build_kernel.sh umi ksu
     

   另外，buildall.sh 可一次性为所有设备构建。

English:

1. Prepare the build environment.
   You need git, make, curl, bison, flex, zip, etc.

   • On Debian/Ubuntu:

   sudo apt install build-essential git curl wget bison flex zip bc cpio libssl-dev ccache tar
   

   You also need python (not just python3):

   sudo apt install python-is-python3
   

   • On RHEL/RPM-based OS:

   sudo yum groupinstall 'Development Tools'
   sudo yum install wget bc openssl-devel ccache tar
   

   Note: ccache is enabled in build.sh ($HOME/.cache/ccache_mikernel). You may remove/modify it.

2. Download ZyC-Clang v16 toolchain:

   mkdir zyc-clang
   cd zyc-clang
   wget https://github.com/ZyCromerZ/Clang/releases/download/16.0.6-20260807-release/Clang-16.0.6-20260807.tar.gz
   tar -zxvf Clang-16.0.6-20260807.tar.gz
   cd ..
   

3. Build:

   • Without KernelSU:

     bash build_kernel.sh TARGET_DEVICE TARGET_OS(omit to build for all)
     

   • With KernelSU:

     bash build.sh TARGET_DEVICE ksu TARGET_OS(omit to build for all)
     

   Example:

   • lmi (Redmi K30 Pro/POCO F2 Pro) without KernelSU, compile for MIUI:

     bash build_kernel.sh lmi miui
     

   • cmi (Xiaomi 10 Pro) with KernelSU, compile for MIUI:

     bash build_kernel.sh cmi ksu miui
     

   • umi (Xiaomi 10) with KernelSU, compile for AOSP and MIUI:

     bash build_kernel.sh umi ksu
     

   Additionally, buildall.sh can build for all supported devices at once.
