How to intregate ReSukiSU

Notes

This document modified from KernelSU Official Documentation

ReSukiSU can be integrated into non-GKI kernels and was backported to 4.9 and earlier versions.

Due to the fragmentation of non-GKI kernels, we don't have a universal way to build them; therefore, we cannot provide a non-GKI boot.img. However, you can build the kernel with ReSukiSU integrated on your own.

First, you should be able to build a bootable kernel from kernel source code. If the kernel isn't open source, then it is difficult to run ReSukiSU for your device.

If you're able to build a bootable kernel, you can add ReSukiSU into your kernel by following this guide.

Building Kernel

WARNING

This part is for GKI devices

Sync the kernel source code

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

The <kernel_manifest.xml> file is a manifest that uniquely identifies a build, allowing you to make it reproducible. To do this, you should download the manifest file from GKI release builds.

Build

Please check the Building kernels first.

For example, to build an aarch64 kernel image:

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

Don't forget to add the LTO=thin flag; otherwise, the build may fail if your computer has less than 24 GB of memory.

Starting from Android 13, the kernel is built by bazel:

tools/bazel build --config=fast //common:kernel_aarch64_dist

Build kernel with ReSukiSU

First, add ReSukiSU to your kernel source tree:

curl -LSs "https://raw.githubusercontent.com/ReSukiSU/ReSukiSU/main/kernel/setup.sh" | bash -s builtin

TIP

Keep in mind that, on some devices, your defconfig may be located at arch/arm64/configs or in other cases, it may be at arch/arm64/configs/vendor/your_defconfig. Regardless of the defconfig you're using, make sure to enable CONFIG_KSU with y to enable or n to disable it. For example, if you choose to enable it, your defconfig should contain the following string：

arch/arm64/configs/...

diff

+# ReSukiSU
+CONFIG_KSU=y
+CONFIG_KSU_MANUAL_HOOK=y

Then,add ReSukiSU's hooks into your kernel, and build your kernel again, and ReSukiSU should work correctly.
