⚡ Key Highlights

• Power Efficiency: Tickless idle (CONFIG_NO_HZ_IDLE=y) and tuned schedutil governor for optimal battery standby and deep sleep.
• Zero-Overhead Memory: Default LZ4 ZRAM compression for rapid memory swapping with near-zero CPU overhead.
• KMI Safe (Hardware Protection): 100% GKI 2.0 ABI compliance. Wi-Fi (qca_cld3_wlan.ko) and Audio (snd-soc-*.ko) OEM vendor modules load without CRC symbol mismatch.
• Debloated Tracing: Stripped heavy debugging routines (SLUB_DEBUG, DEBUG_INFO_BTF, DYNAMIC_DEBUG_CORE, PM_DEBUG) to minimize RAM footprint.
• Network Performance: TCP BBR congestion control enabled by default for lower packet latency and stable throughput.
• ThinLTO: Link-Time Optimization enabled for optimized binary size and cache utilization.
• Modular Configuration: Battery and performance tweaks codified cleanly in configs/zerobyte_battery.config.

📦 Kernel Variants

Every build automatically generates flashable ZIP packages available under Releases:

Variant	Purpose	Root Compatibility
Original	Clean GKI kernel for everyday stability	Play Integrity & Banking ready (Supports Magisk / APatch separately)
KernelSU	Integrated kernel-level root solution	Native KernelSU-Next driver built-in (Install KernelSU Manager app)

🚀 Installation Guide

Important

Always backup your stock boot partition in recovery before flashing any custom kernel!

Flashing via Custom Recovery (TWRP / OrangeFox)

1. Download your preferred kernel variant (Original or KernelSU) from Releases.
2. Boot into recovery (TWRP / OrangeFox).
3. Select Install and choose the downloaded .zip file.
4. Swipe to confirm flash (AnyKernel3 will display the ZeroByte ASCII banner).
5. Reboot System (Wipe cache/dalvik is optional).

Alternatively, you can flash the .zip directly using KernelSU Manager or Franco Kernel Manager.

💻 Local Compilation (build.sh)

You can compile ZeroByte Kernel locally on Linux / WSL with a single command:

# Clone the repository
git clone https://github.com/zacxyonly/zerobyte-kernel.git
cd zerobyte-kernel

# Build KernelSU-Next variant (automatically handles toolchain & kernel tree):
./build.sh --variant ksu

# Build Original (clean / non-root) variant:
./build.sh --variant original

# Build both variants:
./build.sh --variant all

Compiled flashable .zip packages and SHA256 checksums will be generated in out/.

🛠️ Automated CI/CD Build

Builds are also fully automated via GitHub Actions:

1. Navigate to Actions.
2. Select Build ZeroByte Kernel for Realme P3 5G (RMX5079 / dongfeng).
3. Click Run workflow (select variant and ThinLTO option).
4. Flashable ZIP packages and SHA256 checksums will be published to Releases.
