The Three Build Workflows

01 // AUTOMATED CRON ↗
YASK Pipeline

Automated weekly release triggered every Sunday. Builds 4 parallel variants (GKI/CLO × KSU/noksu) with Clang Full LTO, Wild-KSU canary, and Baseband Guard. Deploys GitHub Release & Telegram notification.

4 variants LTO Full Cron
02 // RAPID MANUAL ↗
Main Build

Lightweight manual dispatch workflow for quick prototyping from any repository branch. Supports noksu, ksu, or both with Thin LTO and stable Wild-KSU. Direct Telegram document delivery.

Thin LTO Stable KSU Fast
03 // DEEP TUNING ↗
Advanced Build

Deep tuning compilation engine. Configure compiler optimization (-O2, -O3, -Os), timer frequency (100–1000 Hz), LTO thin/full, and dual toolchain switching (AOSP Clang vs Greenforce).

O2/O3/Os 100–1000Hz 2 Toolchains

Shared Infrastructure Core

📦 AnyKernel3 Packaging

Standardized flashable ZIP generation for recovery flashing across all workflow output artifacts with auto-detection.

💉 Unified Patch System

Automated sign-builds, no-dirty flag injection, GKI boot fixup, and defconfig sanitization before compilation begins.

🔄 Dynamic Swap Expansion

10–20 GB runner swap space allocation to completely prevent Out-Of-Memory (OOM) compiler crashes during heavy LTO linking.

GKI vs CLO Image Guide

GKI (Generic Kernel Image)

Standard Google-compliant kernel architecture. Ideal for generic custom ROMs and devices utilizing standardized GKI boot partitions (e.g., Redmi Pad SE).

CLO (Qualcomm CodeLinaro)

Qualcomm proprietary optimized tree tailored with chipset-specific driver enhancements for Snapdragon 685 display panels and camera sensors.

技 // OPTIMIZATIONS & MODULES

Kernel Engine Features

Key architectural improvements, security modules, and performance patches integrated into the kernel.

⚡ Clang LTO (Link-Time Optimization)

Full cross-translation unit optimization. Eliminates dead code, inlines hot functions across object boundaries, and maximizes execution throughput.

Thin LTO Full LTO
🌐 TCP BBR + Westwood

Modern congestion control algorithms. TCP Westwood is enabled by default to dramatically reduce packet loss and bufferbloat over volatile mobile cellular data connections.

BBR v1 Westwood Default
🛡️ Baseband Guard (BBG)

Custom Linux Security Module (LSM) protecting the baseband and modem interfaces against unauthorized tampering and privilege escalation attacks.

LSM Hook Modem Isolation
🔑 Wild KernelSU + SUSFS

Next-generation kernel-based root hook. Paired with SUSFS kernel patches for complete stealth (spoofing uname, magic mount hiding, kallsyms stripping).

SUSFS v1.5+ Play Integrity Pass
🔄 Dynamic Swap & ZRAM

Runner swap allocation of up to 20 GB ensuring high memory-pressure builds succeed without clang-ld fatal terminations.

20GB Swap ZRAM Support
💉 Automated Tree Fixups

Automated git dirty flag suppression, patch signature validation, and defconfig auto-merging integrated directly into the pre-build pipeline.

Auto Patch No-Dirty

快 // RAPID MANUAL DISPATCH

Main Build Workflow

Quick turnaround compilation workflow for rapid kernel testing and debugging.

The Main Build (main.yml) is designed for developer experimentation. It uses Thin LTO for rapid compilation times while retaining performance optimizations, and packages stable Wild-KSU.

Workflow Input Parameters

Input Variable Type Description Default / Example
kernelSourceURL string Git URL of the target kernel source tree https://github.com/...
kernelBranch string Target branch to clone and checkout 14.0, 15.0, staging
kernelDevice string Target device defconfig name vendor/bengal-perf_defconfig
buildKSU choice KSU inclusion mode: noksu, ksu, or both ksu
創 // MAXIMUM TUNING CONTROL

Advanced Build Engine

Fine-grained compilation parameter matrix for kernel engineers and tuners.

⚠
Case Sensitivity Notice: The parameter LTOOptimizations requires exact casing in workflow dispatch to properly propagate flags to the build environment.

Advanced Parameter Controls

Compiler Optimization Level

Select between -O2 (standard balance), -O3 (aggressive vectorization and loop unrolling for peak performance), or -Os (size optimized).

Timer Tick Frequency (HZ)

Configure kernel timer interrupt frequency between 100Hz (battery saver), 250Hz, 300Hz (standard), and 1000Hz (ultra-low latency gaming).

Toolchain Selector

Switch between standard Google AOSP Clang (clang-r584948b) and custom optimized Greenforce Clang with latest LLVM backend patches.

KernelSU & SUSFS Integration

Kernel-level privilege management combined with SUSFS evasion mechanisms.

ℹ
Stealth Architecture: SUSFS patches intercept sys_call tables and VFS layers to hide mounted overlayfs directories, strip KernelSU symbols from /proc/kallsyms, and bypass Play Integrity / root detectors seamlessly.
