-# SukiSU Ultra
-
-**English** | [简体中文](README.md) | [日本語](README-ja.md) | [Türkçe](README-tr.md)
-
-Android device root solution based on [KernelSU](https://github.com/tiann/KernelSU)
-
-**Experimental! Use at your own risk!** This solution is based on [KernelSU](https://github.com/tiann/KernelSU) and is experimental!
-
-> This is an unofficial fork. All rights are reserved to [@tiann](https://github.com/tiann)
->
-> However, we will be a separately maintained branch of KSU in the future
-
-## How to add
-
-Using main branching (non-GKI device builds are not supported)
-```
-curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
-```
-
-Using branches that support non-GKI devices
-```
-curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s nongki
-```
-
-## How to use integrated susfs
-
-1. Use the susfs-dev branch directly without any patching
-
-```
-curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s susfs-dev
-```
-
-## KPM Support
-
-- Based on KernelPatch, we have removed duplicates of KSU and kept only KPM support.
-- We will introduce more APatch-compatible functions to ensure the integrity of KPM functionality.
-
-We will introduce more APatch-compatible functions to ensure the completeness of KPM functionality.
-
-KPM templates: https://github.com/udochina/KPM-Build-Anywhere
-
-> [!Note]
-> 1. `CONFIG_KPM=y` needs to be added.
-> 2. Non-GKI devices need to add `CONFIG_KALLSYMS=y` and `CONFIG_KALLSYMS_ALL=y` as well.
-> 3. Some kernel source code below `4.19` also needs to be backport from `4.19` to the header file `set_memory.h`.
-
-## How to do a system update to retain ROOT
-- After OTA, don't reboot first, go to the manager flashing/patching kernel interface, find `GKI/non_GKI install` and select the Anykernel3 kernel zip file that needs to be flashed, select the slot that is opposite to the current running slot of the system for flashing, and then reboot to retain the GKI mode update （This method is not supported for all non-GKI devices, so please try it yourself. It is the safest way to use TWRP for non-GKI devices.）
-- Or use LKM mode to install to the unused slot (after OTA).
-
-## Compatibility Status
-- KernelSU (versions prior to v1.0.0) officially supports Android GKI 2.0 devices (kernel 5.10+)
-
-- Older kernels (4.4+) are also compatible, but the kernel must be built manually
-
-- KernelSU can support 3.x kernels (3.4-3.18) through additional reverse ports
-
-- Currently supports `arm64-v8a`, `armeabi-v7a (bare)` and some `X86_64`
-

-Projects compiled based on Sukisu and susfs
-- [GKI](https://github.com/ShirkNeko/GKI_KernelSU_SUSFS) 
-- [OnePlus](https://github.com/ShirkNeko/Action_OnePlus_MKSU_SUSFS)
-
-## Hook method
-- This method references the hook method from (https://github.com/rsuntk/KernelSU)
-
-1. **KPROBES hook:**
-    - Also used for Loadable Kernel Module (LKM)
-    - Default hook method on GKI kernels.
-    - Need `CONFIG_KPROBES=y`
-
-2. **Manual hook:**
-    - Standard KernelSU hook: https://kernelsu.org/guide/how-to-integrate-for-non-gki.html#manually-modify-the-kernel-source
-    - backslashxx's syscall manual hook: https://github.com/backslashxx/KernelSU/issues/5
-    - Default hook method on Non-GKI kernels.
-    - Need `CONFIG_KSU_MANUAL_HOOK=y`
-
-## Usage
-
-### Universal GKI
-
-Please **all** refer to https://kernelsu.org/zh_CN/guide/installation.html
-
-> [!Note]
-> 1. for devices with GKI 2.0 such as Xiaomi, Redmi, Samsung, etc. (excludes kernel-modified manufacturers such as Meizu, OnePlus, Zenith, and oppo)
-> 2. Find the GKI build in [more links](#%E6%9B%B4%E5%A4%9A%E9%93%BE%E6%8E%A5). Find the device kernel version. Then download it and use TWRP or kernel flashing tool to flash the zip file with AnyKernel3 suffix.
-> 3. The .zip archive without suffix is uncompressed, the gz suffix is the compression used by Tenguet models.
-
-
-### OnePlus
-
-1. Use the link mentioned in the 'More Links' section to create a customized build with your device information, and then flash the zip file with the AnyKernel3 suffix.
-
-> [!Note]
-> - You only need to fill in the first two parts of kernel versions, such as 5.10, 5.15, 6.1, or 6.6.
-> - Please search for the processor codename by yourself, usually it is all English without numbers.
-> - You can find the branch and configuration files from the OnePlus open-source kernel repository.
-
-## Features
-
-1. Kernel-based `su` and root access management.
-2. Not based on [OverlayFS](https://en.wikipedia.org/wiki/OverlayFS) module system, but based on [Magic Mount](https://github.com/5ec1cff/KernelSU) from 5ec1cff
-3. [App Profile](https://kernelsu.org/guide/app-profile.html): Lock root privileges in a cage. 
-4. Bringing back non-GKI/GKI 1.0 support
-5. More customization
-6. Support for KPM kernel modules

-
-**試験中なビルドです！自己責任で使用してください！**<br>
-このソリューションは [KernelSU](https://github.com/tiann/KernelSU) に基づいていますが、試験中なビルドです。
-
-> これは非公式なフォークです。すべての権利は [@tiann](https://github.com/tiann) に帰属します。
->
-> ただし、将来的には KSU とは別に管理されるブランチとなる予定です。
-
-## 追加方法
-
-メイン分岐の使用（GKI デバイス以外のビルドはサポートされていません。）
-```
-curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
-```
-
-GKI以外のデバイスをサポートするブランチを使用する
-```

-
-## ROOT を保持するシステムアップデートの方法
-- OTAの後、最初に再起動せず、マネージャのフラッシュ/パッチカーネルインターフェイスに移動し、`GKI/non_GKI 取り付け`を見つけ、フラッシュする必要があるAnykernel3カーネルzipファイルを選択し、フラッシュするためにシステムの現在の実行スロットと反対のスロットを選択し、GKIモードアップデートを保持するために再起動します（この方法は、現時点ではすべてのnon_GKIデバイスでサポートされていませんので、各自でお試しください。 (この方法は、すべての非GKIデバイスでサポートされていませんので、ご自身でお試しください)。
-- または、LKMモードを使用して未使用のスロットにインストールします(OTA後)。
-
-## 互換性ステータス
-- KernelSU（v1.0.0より前のバージョン）はAndroid GKI 2.0デバイス（カーネル5.10以上）を公式にサポートしています。
-
-- 古いカーネル（4.4+）も互換性がありますが、カーネルは手動でビルドする必要があります。
-
-- KernelSU は追加のリバースポートを通じて 3.x カーネル (3.4-3.18) をサポートしています。
-
-- 現在は `arm64-v8a`、`armeabi-v7a (bare)`、いくつかの `X86_64` をサポートしています。

-## フックの方式
-
-- この方式は (https://github.com/rsuntk/KernelSU) のフック方式を参照してください。
-
-1. **KPROBES フック:**
-    - 読み込み可能なカーネルモジュールの場合 (LKM)
-    - GKI カーネルのデフォルトとなるフック方式
-    - `CONFIG_KPROBES=y` が必要です
-
-2. **手動でフック:**
-    - 標準の KernelSU フック: https://kernelsu.org/guide/how-to-integrate-for-non-gki.html#manually-modify-the-kernel-source
-    - backslashxx syscall フック: https://github.com/backslashxx/KernelSU/issues/5
-    - 非 GKI カーネル用のデフォルトフッキングメソッド
-    - `CONFIG_KSU_MANUAL_HOOK=y` が必要です
-
-## 使い方
-
-### ユニバーサルGKI
-
-https://kernelsu.org/zh_CN/guide/installation.html をご参照ください。
-
-> [!Note]
-> 1.Xiaomi、Redmi、Samsung などの GKI 2.0 を搭載したデバイス用 (Meizu、Yiga、Zenith、oppo などのマジックカーネルを搭載したメーカーは除く)。
-> 2. [more links](#%E6%9B%B4%E5%A4%9A%E9%93%BE%E6%8E%A5) で GKI ビルドを検索します。 デバイスのカーネルバージョンを検索します。 次に、それをダウンロードし、TWRPまたはカーネルフラッシングツールを使用して、AnyKernel3の接尾辞が付いたzipファイルをフラッシュします。
-> 接尾辞なしの.zipアーカイブは非圧縮で、接尾辞gzはTenguetモデルで使用されている圧縮方法です。
-### OnePlus
-
-1. `その他のリンク`の項目に記載されているリンクを開き、デバイス情報を使用してカスタマイズされたカーネルをビルドし、AnyKernel3 の接頭辞を持つ .zip ファイルをフラッシュします。
-
-> [!Note]

+
+## Features
+
+1. Kernel-based `su` and root access management
+2. Module system based on [Magic Mount](https://github.com/5ec1cff/KernelSU)
+   > **Note:** SukiSU now delegates all module mounting to the installed *metamodule*; the core no longer handles mount operations.
+3. [App Profile](https://kernelsu.org/guide/app-profile.html): Lock up the root power in a cage
+4. Support non-GKI and GKI 1.0
+5. KPM Support
+6. Tweaks to the manager theme and the built-in susfs management tool.
+
+## Compatibility Status
+
+- KernelSU (before v1.0.0) officially supports Android GKI 2.0 devices (kernel 5.10+).
+
+- Older kernels (4.4+) are also compatible, but the kernel will have to be built manually.
+
+- With more backports, KernelSU can supports 3.x kernel (3.4-3.18).
+
+- Currently, only `arm64-v8a`, `armeabi-v7a (bare)` and `X86_64`(some) are supported.
+
+## Installation
+
+See [`guide/installation.md`](guide/installation.md)
+
+## Integration
+
+See [`guide/how-to-integrate.md`](guide/how-to-integrate.md)
+
+## Translation
+
+If you need to submit a translation for the manager, please go to [Crowdin](https://crowdin.com/project/SukiSU-Ultra).
+
+## KPM Support
+
+- Based on KernelPatch, we removed features redundant with KSU and retained only KPM support.
+- Work in Progress: Expanding APatch compatibility by integrating additional functions to ensure compatibility across different implementations.
+
+**Open-source repository**: [https://github.com/ShirkNeko/SukiSU_KernelPatch_patch](https://github.com/ShirkNeko/SukiSU_KernelPatch_patch)
+
+**KPM template**: [https://github.com/udochina/KPM-Build-Anywhere](https://github.com/udochina/KPM-Build-Anywhere)
+
+> [!Note]
 >
-> 但是，我们将会在未来成为一个单独维护的 KSU 分支
+> 1. Requires `CONFIG_KPM=y`
+> 2. Non-GKI devices requires `CONFIG_KALLSYMS=y` and `CONFIG_KALLSYMS_ALL=y`
+> 3. For kernels below `4.19`, backporting from `set_memory.h` from `4.19` is required.
 
-## 如何添加
+## Troubleshooting
 
-在内核源码的根目录下执行以下命令：
+1. Device stuck upon manager app uninstallation?
+   Uninstall _com.sony.playmemories.mobile_
 
-使用 main 分支 (不支持非GKI设备构建)
+## Sponsor
-```
-curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
-```

-## 如何进行系统更新保留ROOT
-- OTA后先不要重启，进入管理器刷写/修补内核界面，找到 `GKI/non_GKI安装` 选择需要刷写的Anykernel3内核压缩文件，选择与现在系统运行槽位相反的槽位进行刷写并重启即可保留GKI模式更新（暂不支持所有非GKI设备使用这种方法，请自行尝试。非GKI设备使用TWRP刷写是最稳妥的）

-
-## 兼容状态
-- KernelSU（v1.0.0 之前版本）正式支持 Android GKI 2.0 设备（内核 5.10+）
-
-- 旧内核（4.4+）也兼容，但必须手动构建内核
-
-- 通过更多的反向移植，KernelSU 可以支持 3.x 内核（3.4-3.18）
-
-- 目前支持 `arm64-v8a` ，`armeabi-v7a (bare)` 和部分 `X86_64`

+# Integrate
+
+SukiSU can be integrated into both _GKI_ and _non-GKI_ kernels and has been backported to _4.14_.
+
+<!-- It should be 3.4, but backslashxx's syscall manual hook cannot use in SukiSU-->
+
+Some OEMs' customization could result in as much as 50% of kernel code being out-of-tree code and not from upstream Linux kernels or ACKs. Due to this, the custom nature of _non-GKI_ kernels resulted in significant kernel fragmentation, and we lacked a universal method for building them. Therefore, we cannot provide boot images of _non-GKI_ kernels.
+
+Prerequisites: open source bootable kernel.
+
+### Hook method
+
+1. **KPROBES hook:**
+
+   - Default hook method on GKI kernels.
+   - Requires `# CONFIG_KSU_MANUAL_HOOK is not set` & `CONFIG_KPROBES=y`
+   - Used for Loadable Kernel Module (LKM).
+
+2. **Manual hook:**
+
+   <!-- - backslashxx's syscall manual hook: https://github.com/backslashxx/KernelSU/issues/5 (v1.5 version is not available at the moment, if you want to use it, please use v1.4 version, or standard KernelSU hooks)-->
+
+   - Requires `CONFIG_KSU_MANUAL_HOOK=y`
+   - Requires [`guide/how-to-integrate.md`](guide/how-to-integrate.md)
+   - Requires [https://github.com/~](https://github.com/tiann/KernelSU/blob/main/website/docs/guide/how-to-integrate-for-non-gki.md#manually-modify-the-kernel-source)
+
+3. **Tracepoint Hook:**
+
+   - Hook method introduced since SukiSU commit [49b01aad](https://github.com/SukiSU-Ultra/SukiSU-Ultra/commit/49b01aad74bcca6dba5a8a2e053bb54b648eb124)
+   - Requires `CONFIG_KSU_TRACEPOINT_HOOK=y`
+   - Requires [`guide/tracepoint-hook.md`](tracepoint-hook.md)
+
+<!-- This part refer to [rsuntk/KernelSU](https://github.com/rsuntk/KernelSU). -->
+
+If you're able to build a bootable kernel, there are two ways to integrate KernelSU into the kernel source code:
+
+1. Automatically with `kprobe`
+2. Manually
+
+## Integrate with kprobe
+
+Applicable:
+
+- _GKI_ kernel
+
+Not applicable:
+
+- _non-GKI_ kernel
+
+KernelSU uses kprobe to do kernel hooks. If kprobe runs well in your kernel, it's recommended to use it this way.
+
+Please refer to this document [https://github.com/~](https://github.com/tiann/KernelSU/blob/main/website/docs/guide/how-to-integrate-for-non-gki.md#integrate-with-kprobe). Although it is titled “for _non-GKI_,” it only applies to _GKI_.
+
+The execution command for the step that adds KernelSU to your kernel source tree is replaced with:
+
+```sh
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
+```
+
+## Manually modify the kernel source
+
+Applicable:
+
+- GKI kernel
+- non-GKI kernel
+
+Please refer to this document [https://github.com/~ (Integrate for non-GKI)](https://github.com/tiann/KernelSU/blob/main/website/docs/guide/how-to-integrate-for-non-gki.md#manually-modify-the-kernel-source) and [https://github.com/~ (Build for GKI)](https://kernelsu.org/zh_CN/guide/how-to-build.html) to integrate manually, although first link is titled “for non-GKI,” it also applies to GKI. It can work on them both.
+
+There is another way to integrate but still work in the process.
+
+<!-- It is backslashxx's syscall manual hook, but it cannot be used now. -->
+
+Run command for the step that adds KernelSU(SukiSU) to your kernel source tree is replaced with:
+
+### GKI kernel
+
+```sh
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
+```
+
+### non-GKI kernel
+
+```sh
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s nongki
+```
+
+### GKI / non-GKI kernel with susfs (experiment)
+
+```sh
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s susfs-{{branch}}
+```
+
+Branch:
+
+- `main` (susfs-main)
+- `test` (susfs-test)
+- version (for example: susfs-1.5.7, you should check the [branches](https://github.com/SukiSU-Ultra/SukiSU-Ultra/branches))

+# Installation
+
+You can go to [KernelSU Documentation - Installation](https://kernelsu.org/guide/installation.html) for a reference on how to install it, here are just additional instructions.
+
+## Installation by loading the Loadable Kernel Module(LKM)
+
+See [KernelSU Documentation - LKM Installation](https://kernelsu.org/guide/installation.html#lkm-installation)
+
+Beginning with **Android™** (trademark meaning licensed Google Mobile Services) 12, devices shipping with kernel version 5.10 or higher must ship with the GKI kernel. You may be able to use LKM mode.
+
+## Installation by installing the kernel
+
+See [KernelSU Documentation - GKI mode Installation](https://kernelsu.org/guide/installation.html#gki-mode-installation)
+
+We provide pre-built kernels for you to use:
+
+- [ShirkNeko flavor kernel](https://github.com/ShirkNeko/GKI_KernelSU_SUSFS) (add ZRAM compression algorithm patch, susfs, KPM. Works on many devices.)
+- [MiRinFork flavored kernel](https://github.com/MiRinFork/GKI_SukiSU_SUSFS) (adds susfs, KPM. Closest kernel to GKI, works on most devices.)
+
+Although some devices can be installed using LKM mode, they cannot be installed on the device by using the GKI kernel; therefore, the kernel needs to be modified manually to compile it. For example:
+
+- OPPO(OnePlus, REALME)
+- Meizu
+
+Also, we provide pre-built kernels for your OnePlus device to use:
+
+- [ShirkNeko/Action_OnePlus_MKSU_SUSFS](https://github.com/ShirkNeko/Action_OnePlus_MKSU_SUSFS) (add ZRAM compression algorithm patch, susfs, KPM.)
+
+Using the link above, Fork into GitHub Action, fill in the build parameters, compile, and finally flush in the zip with the AnyKernel3 suffix.
+
+> [!Note]
+>
+> - You only need to fill in the first two parts of the version number, e.g. `5.10`, `6.1`...
+> - Make sure you know the processor designation, kernel version, etc. before you use it.

+# Tracepoint Hook Integration
+
+## Introduction
+
+Since commit [49b01aad](https://github.com/SukiSU-Ultra/SukiSU-Ultra/commit/49b01aad74bcca6dba5a8a2e053bb54b648eb124), SukiSU has introduced Tracepoint Hook
+
+This Hook theoretically has lower performance overhead compared to Kprobes Hook, but is inferior to Manual Hook / Syscall Hook
+
+> [!NOTE]
+> This tutorial references the syscall hook v1.4 version from [backslashxx/KernelSU#5](https://github.com/backslashxx/KernelSU/issues/5), as well as the original KernelSU's [Manual Hook](https://kernelsu.org/guide/how-to-integrate-for-non-gki.html#manually-modify-the-kernel-source)

+
+[KernelSU](https://github.com/tiann/KernelSU) をベースとした Android デバイスの root ソリューション
+
+**試験中なビルドです！自己責任で使用してください！**<br>
+このソリューションは [KernelSU](https://github.com/tiann/KernelSU) に基づいていますが、試験中なビルドです。
+
+> これは非公式なフォークです。すべての権利は [@tiann](https://github.com/tiann) に帰属します。
+>
+> ただし、将来的には KSU とは別に管理されるブランチとなる予定です。
+
+## 追加する方法
+
+メインブランチを使用 (非 GKI のデバイスのビルドは非対応) (susfs を手動で統合が必要)
+
+```
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
+```
+
+非 GKI のデバイスに対応するブランチを使用 (susfs を手動で統合が必要)
+
+```
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s nongki
+```
+
+## 統合された susfs の使い方
+
+1. susfs-main または他の susfs-\* ブランチを直接で使用、susfs の統合は不要 (非 GKI デバイスのビルドに対応)
+
+```
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s susfs-main
+```
+
+## フックの方式
+
+- この方式は (https://github.com/rsuntk/KernelSU) のフック方式を参照してください。
+
+1. **KPROBES でフック:**
+
+   - 読み込み可能なカーネルモジュールの場合 (LKM)
+   - GKI カーネルのデフォルトとなるフック方式
+   - `CONFIG_KPROBES=y` が必要です
+
+2. **手動でフック:**
+   - 標準の KernelSU フック: https://kernelsu.org/guide/how-to-integrate-for-non-gki.html#manually-modify-the-kernel-source
+   - backslashxx syscall フック: https://github.com/backslashxx/KernelSU/issues/5
+   - 非 GKI カーネル用のデフォルトフック方式
+   - `CONFIG_KSU_MANUAL_HOOK=y` が必要です
+
+## KPM に対応
+
+- KernelPatch に基づいて重複した KSU の機能を削除、KPM の対応を維持させています。
+- KPM 機能の整合性を確保するために、APatch の互換機能を更に向上させる予定です。
+
+オープンソースアドレス: https://github.com/ShirkNeko/SukiSU_KernelPatch_patch
+
+KPM テンプレートのアドレス: https://github.com/udochina/KPM-Build-Anywhere
+
+> [!Note]
+>
+> 1. `CONFIG_KPM=y` が必要です。
+> 2. 非 GKI デバイスには `CONFIG_KALLSYMS=y` と `CONFIG_KALLSYMS_ALL=y` も必要です。
+> 3. いくつかのカーネル `4.19` およびそれ以降のソースコードでは、 `4.19` からバックポートされた `set_memory.h` ヘッダーファイルも必要です。
+
+## ROOT を保持した状態でのシステムアップデートの方法
+
+- 始めに OTA 後すぐに再起動せずにマネージャーのカーネルのフラッシュ、パッチのインターフェースを開いて`GKI/非 GKI のインストール`を見つけます。フラッシュする AnyKernel3 の zip ファイルを選択し、フラッシュする実行中のスロットと逆のスロットを選択後に再起動をして GKI モードの更新が保持できます (この方法はすべての非 GKI のデバイスが対応している訳ではないので、自分でお試しください。これは非 GKI のデバイスで TWRP を使用する最も安全な方法です)。
+- または LKM モードを使用して未使用のスロットにインストールします (OTA 後)。
+
+## 互換性の状態
+
+- KernelSU (v1.0.0 より前) は Android GKI 2.0 のデバイス (カーネル 5.10 以降) を公式に対応しています。
+
+- 古いカーネル (4.4 以降) も互換性がありますが、カーネルを手動で再ビルドする必要があります。
+
+- KernelSU は追加のリバースポートを通じて 3.x カーネル (3.4-3.18) で対応可能です。
+
+- 現在 `arm64-v8a`, `armeabi-v7a (bare)` および一部の `X86_64` に対応しています。
+
+## その他のリンク
+
+**マネージャーの翻訳を行う場合** https://crowdin.com/project/SukiSU-Ultra
+
+- [その他パッチ済み GKI](https://github.com/ShirkNeko/GKI_KernelSU_SUSFS) ZRAM パッチ、KPM、susfs が含まれています...
+- [パッチの少ない GKI](https://github.com/MiRinFork/GKI_SukiSU_SUSFS/releases) susfs のみ
+- [OnePlus](https://github.com/ShirkNeko/Action_OnePlus_MKSU_SUSFS)
+
+## 使い方
+
+### Universal GKI
+
+**すべて**参照してください https://kernelsu.org/ja_JP/guide/installation.html
+
+> [!Note]
+>
+> 1. Xiaomi、Redmi、Samsung などの GKI 2.0 を搭載したデバイス向け (Meizu、OnePlus、Zenith、Oppo などカーネルが変更されているメーカーを除く)
+> 2. GKI のビルドは[その他のリンク](#その他のリンク)から入手できます。デバイスのカーネルバージョンを確認してください。ダウンロード後に TWRP またはカーネルフラッシュツールを使用して AnyKernel3 の接頭辞を持つ zip ファイルをフラッシュしてください。Pixel のユーザーは、パッチの少ない GKI を使用する必要があります。
+> 3. 接頭辞のない .zip アーカイブは圧縮されていません。.gz の接頭辞は Tenguet モデルで使用される圧縮になります。
+
+### OnePlus
+
+1. `その他のリンク`の項目に記載されているリンクを開き、デバイス情報を使用してカスタマイズされたカーネルをビルドし、AnyKernel3 の接頭辞を持つ .zip ファイルをフラッシュします。
+
+> [!Note]
+>
+> - 5.10、5.15、6.1、6.6 などのカーネルバージョンの最初の 2 文字のみを入力する必要があります。
+> - SoC のコードネームは自分で検索してください。通常は、数字がなく英語表記のみです。
+> - ブランチと構成ファイルは、OnePlus オープンソースカーネルリポジトリから見つけることができます。
+
+## 機能
+
+1. カーネルベースな `su` および root アクセスの管理。
+2. [OverlayFS](https://en.wikipedia.org/wiki/OverlayFS) モジュールシステムではなく、 5ec1cff 氏の [Magic Mount](https://github.com/5ec1cff/KernelSU) に基づいています。
+3. [アプリプロファイル](https://kernelsu.org/guide/app-profile.html): root 権限をケージ内にロックします。
+4. 非 GKI / GKI 1.0 の対応を復活
+5. その他のカスタマイズ
+6. KPM カーネルモジュールに対応
+
+## トラブルシューティング
+
+1. KernelSU Manager のアンインストールが停止してしまう → com.sony.playmemories.mobile のアプリをアンインストールしてください。

+
+## 特性
+
+1. 基于内核的 `su` 和权限管理。
+2. 基于 [Magic Mount](https://github.com/5ec1cff/KernelSU) 的模块系统。
+3. [App Profile](https://kernelsu.org/zh_CN/guide/app-profile.html): 把 Root 权限关进笼子里。
+4. 支持 non-GKI 与 GKI 1.0。
+5. KPM 支持
+6. 可调整管理器外观，可自定义 susfs 配置。
+
+## 兼容状态
+
+- KernelSU 官方支持 GKI 2.0 的设备（内核版本 5.10 以上）。
+
+- 旧内核也是兼容的（最低 4.14+），不过需要自己编译内核。
+
+- 通过更多的反向移植，KernelSU 可以支持 3.x 内核（3.4-3.18）。
+
+- 目前支持架构 : `arm64-v8a`、`armeabi-v7a (bare)`、`X86_64`。
+
+## 安装指导

+
+## 参与翻译
+
+要将 SukiSU 翻译成您的语言，或完善现有的翻译，请使用 [Crowdin](https://crowdin.com/project/SukiSU-Ultra).
+
+## KPM 支持
+
+- 基于 KernelPatch 开发，移除了与 KernelSU 重复的功能。
+- 正在进行（WIP）：通过集成附加功能来扩展 APatch 兼容性，以确保跨不同实现的兼容性。
+
+**开源仓库**: [https://github.com/ShirkNeko/SukiSU_KernelPatch_patch](https://github.com/ShirkNeko/SukiSU_KernelPatch_patch)
+
+**KPM 模板**: [https://github.com/udochina/KPM-Build-Anywhere](https://github.com/udochina/KPM-Build-Anywhere)
+
+> [!Note]
+>
+> 1. 需要 `CONFIG_KPM=y`
+> 2. Non-GKI 设备需要 `CONFIG_KALLSYMS=y` and `CONFIG_KALLSYMS_ALL=y`
+> 3. 对于低于 `4.19` 的内核，需要从 `4.19` 的 `set_memory.h` 进行反向移植。
+
+## 故障排除
+
+1. 卸载管理器后系统卡住？
+   卸载 _com.sony.playmemories.mobile_

+# 集成指导
+
+SukiSU 可以集成到 GKI 和 non-GKI 内核中，并且已反向移植到 4.14 版本。
+
+<!-- 应该是 3.4 版本，但 backslashxx 的 syscall manual hook 无法在 SukiSU 中使用-->
+
+有些 OEM 定制可能导致多达 50% 的内核代码超出内核树代码，而非来自上游 Linux 内核或 ACK。因此，non-GKI 内核的定制特性导致了严重的内核碎片化，而且我们缺乏构建它们的通用方法。因此，我们无法提供 non-GKI 内核的启动映像。
+
+前提条件：开源的、可启动的内核。
+
+## Hook 方法
+
+1. **KPROBES hook:**
+
+   - GKI kernels 的默认 hook 方法。
+   - 需要 `# CONFIG_KSU_MANUAL_HOOK is not set`（未设定） & `CONFIG_KPROBES=y`
+   - 用作可加载的内核模块 (LKM).
+
+2. **Manual hook:**
+
+   <!-- - backslashxx's syscall manual hook: https://github.com/backslashxx/KernelSU/issues/5 (v1.5 version is not available at the moment, if you want to use it, please use v1.4 version, or standard KernelSU hooks)-->
+
+   - 需要 `CONFIG_KSU_MANUAL_HOOK=y`
+   - 需要 [`guide/how-to-integrate.md`](how-to-integrate.md)
+   - 需要 [https://github.com/~](https://github.com/tiann/KernelSU/blob/main/website/docs/guide/how-to-integrate-for-non-gki.md#manually-modify-the-kernel-source)
+
+3. **Tracepoint Hook:**
+
+   - 自 SukiSU commit [49b01aad](https://github.com/SukiSU-Ultra/SukiSU-Ultra/commit/49b01aad74bcca6dba5a8a2e053bb54b648eb124) 引入的 hook 方法
+   - 需要 `CONFIG_KSU_TRACEPOINT_HOOK=y`
+   - 需要 [`guide/tracepoint-hook.md`](tracepoint-hook.md)
+   
+<!-- This part refer to [rsuntk/KernelSU](https://github.com/rsuntk/KernelSU). -->
+
+如果您能够构建可启动内核，有两种方法可以将 KernelSU 集成到内核源代码中：
+
+1. 使用 `kprobe` 自动集成
+2. 手动集成
+
+## 与 kprobe 集成
+
+适用：
+
+- GKI 内核
+
+不适用：
+
+- non-GKI 内核
+
+KernelSU 使用 kprobe 机制来做内核的相关 hook，如果 _kprobe_ 可以在你编译的内核中正常运行，那么推荐用这个方法来集成。
+
+请参阅此文档 [https://github.com/~](https://github.com/tiann/KernelSU/blob/main/website/docs/guide/how-to-integrate-for-non-gki.md#integrate-with-kprobe)。虽然标题为“适用于 non-GKI”，但仅适用于 GKI。
+
+替换 KernelSU 添加到内核源代码树的步骤的执行命令为：
+
+```sh
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
+```
+
+## 手动修改内核源代码
+
+适用：
+
+- GKI 内核
+- non-GKI 内核
+
+请参考此文档 [https://github.com/~ (non-GKI 内核集成)](https://github.com/tiann/KernelSU/blob/main/website/docs/guide/how-to-integrate-for-non-gki.md#manually-modify-the-kernel-source) 和 [https://github.com/~ (GKI 内核构建)](https://kernelsu.org/zh_CN/guide/how-to-build.html) 进行手动集成。虽然第一个链接的标题是“适用于 non-GKI”，但它也适用于 GKI。两者都可以正常工作。
+
+还有另一种集成方法，但是仍在开发中。
+
+<!-- 这是 backslashxx 的syscall manual hook，但目前无法使用。 -->
+
+将 KernelSU（SukiSU）添加到内核源代码树的步骤的运行命令将被替换为：
+
+### GKI 内核
+
+```sh
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s main
+```
+
+### non-GKI 内核
+
+```sh
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s nongki
+```
+
+### 带有 susfs 的 GKI / non-GKI 内核（实验）
+
+```sh
+curl -LSs "https://raw.githubusercontent.com/SukiSU-Ultra/SukiSU-Ultra/main/kernel/setup.sh" | bash -s susfs-{{branch}}
+```
+
+分支:
+
+- `main` (susfs-main)
+- `test` (susfs-test)
+- 版本号 (例如： susfs-1.5.7, 你需要在 [分支](https://github.com/SukiSU-Ultra/SukiSU-Ultra/branches) 里找到它)

+# 安装指导
+
+您可以前往 [KernelSU 文档 - 安装](https://kernelsu.org/guide/installation.html) 获取有关如何安装的参考，这里只是额外的说明。
+
+## 通过加载可加载内核模块 (LKM) 进行安装
+
+请参阅 [KernelSU 文档 - LKM 安装](https://kernelsu.org/guide/installation.html#lkm-installation)
+
+从 **Android™**（商标，意为获得 Google 移动服务的许可）12 开始，搭载内核版本 5.10 或更高版本的设备必须搭载 GKI 内核。因此你或许可以使用 LKM 模式。
+
+## 通过安装内核进行安装
+
+请参阅 [KernelSU 文档 - GKI 模式安装](https://kernelsu.org/guide/installation.html#gki-mode-installation)
+
+我们提供预编译的内核供您使用：
+
+- [ShirkNeko 内核](https://github.com/ShirkNeko/GKI_KernelSU_SUSFS)（添加了 ZRAM 压缩算法补丁、susfs 文件和 KPM 文件。适用于很多设备。）
+- [MiRinFork 内核](https://github.com/MiRinFork/GKI_SukiSU_SUSFS)（添加了 susfs 文件和 KPM 文件。最接近 GKI 的内核，适用于大多数设备。）
+
+虽然某些设备可以使用 LKM 模式安装，但无法使用 GKI 内核将其安装到设备上；因此，需要手动修改内核进行编译。例如：
+
+- 欧珀（一加、真我）
+- 魅族
+
+此外，我们还为您的 OnePlus 设备提供预编译的内核：
+
+- [ShirkNeko/Action_OnePlus_MKSU_SUSFS](https://github.com/ShirkNeko/Action_OnePlus_MKSU_SUSFS)（添加 ZRAM 压缩算法补丁、susfs 和 KPM。）
+
+使用上面的链接，Fork 到 GitHub Action，填写构建参数，进行编译，最后将 zip 文件以 AnyKernel3 后缀上传到 GitHub Action。
+
+> [!Note]
+>
+> - 使用时，您只需填写版本号的前两部分，例如 `5.10`、`6.1`...
+> - 使用前请确保您了解处理器名称、内核版本等信息。

+# Tracepoint Hook 集成
+
+## 介绍
+
+自 commit [49b01aad](https://github.com/SukiSU-Ultra/SukiSU-Ultra/commit/49b01aad74bcca6dba5a8a2e053bb54b648eb124) 起，SukiSU 引入了 Tracepoint Hook
+
+该 Hook 理论上相比于 Kprobes Hook，性能开销更小，但次于 Manual Hook / Syscall Hook
+
+> [!NOTE]
+> 本教程参考了 [backslashxx/KernelSU#5](https://github.com/backslashxx/KernelSU/issues/5) 的 syscall hook v1.4 版本钩子，以及原版 KernelSU 的 [Manual Hook](https://kernelsu.org/guide/how-to-integrate-for-non-gki.html#manually-modify-the-kernel-source)
