## Key Features

* Disable Samsung securities, debug drivers, etc modifications

* Compiled with bleeding edge Neutron Clang 17, with full LLVM binutils, LTO (Link time optimization) and -O3
* Import Erofs, Incremental FS, BinderFS and several backports.
* Supports DeX touchpad for corresponding OneUI ports that have DeX ported.
* Lot of debug codes/configuration Samsung added are removed.
* Added [wireguard](https://www.wireguard.com/) driver, an open-source VPN driver in-kernel

## How To Build

You will need ubuntu, git, around 8GB RAM and bla-bla-bla...

```bash
# Install dependencies
$ sudo apt install -y bash git make libssl-dev curl bc pkg-config m4 libtool automake autoconf

# Clone this repository
$ git clone https://github.com/Gojikovi/kernel_samsung_universal9611

# Go into the repository
$ cd kernel_samsung_universal9611

# Install toolchain

You could try any clang/LLVM based toolchain, however I use neutron clang
If you are using Arch or distro with latest glibc, You may want to use antman instead.
$ bash <(curl https://gist.githubusercontent.com/roynatech2544/0feeeb35a6d1782b186990ff2a0b3657/raw/b170134a94dac3594df506716bc7b802add2724b/setup.sh)


# If you want to compile the kernel not for A51 then change the 23 line in build_kernel.sh to f41, m21, m31, m31s
# Build the kernel
$ ./build_kernel.sh aosp ksu # (for AOSP)
$ ./build_kernel.sh oneui ksu # (for OneUI)
```

After build the image of the kernel will be in out/arch/arm64/boot/Image

## How To Flash

After a successful build, you can see the Kernel.zip archive.
This is your kernel. Just flash it via TWRP or adb sideload
