android-kernel 🔧

A GitHub Actions CI pipeline that builds a KernelSU-patched kernel for the Samsung Galaxy A04s (SM-A047F) and packages it as a flashable AnyKernel3 ZIP.

Features

• ⚙️ Automated kernel compilation using Clang 17 with full LLVM toolchain
• 🛡️ KernelSU integration — patches root support directly into the kernel
• 📦 AnyKernel3 packaging — produces a flashable ZIP ready for TWRP / OrangeFox
• 🚀 Optional GitHub Release — automatically publishes the ZIP as a tagged release
• 🔧 Auto-patches Mali GPU Kconfig — fixes Samsung Exynos shell() syntax errors at build time
• 📊 Compile log upload on failure — artifacts are saved for debugging failed builds

Requirements

• A GitHub account with Actions enabled
• No local setup needed — everything runs on GitHub-hosted runners

Usage

1. Fork this repository to your own GitHub account.
2. Go to the Actions tab and select Build Kernel with KernelSU (Samsung A04s).
3. Click Run workflow and fill in the inputs:

Input	Default	Description
kernel_source	SavedByLight/android_kernel_samsung_a04s	Kernel source repo URL
kernel_branch	main	Branch to build from
kernelsu_tag	main	KernelSU release tag, or main for latest
create_release	false	Set to true to publish a GitHub Release

4. The workflow will compile the kernel, package it, and upload the ZIP as a build artifact.

Flashing

1. Download the ZIP from the Artifacts section of the completed Actions run (or from Releases if you enabled it).
2. Boot your Samsung A04s into TWRP or OrangeFox recovery.
3. Flash the ZIP.
4. Reboot to system.
5. Install the KernelSU Manager APK and open it — status should show Working.

How It Works

1. Clones the specified kernel source at the given branch.
2. Fixes script permissions and patches the Mali GPU Kconfig for Samsung Exynos compatibility.
3. Downloads and integrates KernelSU via the official setup script.
4. Sets up Clang 17 from ZyCromerZ/Clang.
5. Configures the kernel using the A04s defconfig with KernelSU and overlay FS enabled.
6. Compiles with make -j$(nproc) using the full LLVM toolchain.
7. Collects DTBs and packages everything with AnyKernel3.
8. Optionally creates a GitHub Release with build metadata.
