Core Task Optimizer: Native C++ Android Performance Module

A high-performance Magisk module written in C++17 that optimizes Android system processes via direct Linux syscalls.

Unlike shell-based optimizers, Core Task Optimizer runs as a native binary, offering nanosecond-level efficiency in adjusting CPU affinity, scheduling policies (SCHED_FIFO), and I/O priorities to eliminate UI lag and reduce touch latency.

⚡ Core Features

• 🚀 Native C++ Architecture: Built with C++17 for minimal overhead and thread-safe execution.
• 🧠 Auto-Adaptive CPU Topology: Dynamically detects Performance vs. Efficiency cores by parsing /sys/devices/system/cpu frequencies. No hardcoded core masks.
• 🎮 GPU & Touch Real-Time Mode: Forces SCHED_FIFO priority on critical threads like kgsl_worker_thread (Adreno GPU) and fts_wq (Touch Panels).
• 🛡️ Syscall-Level Optimization: Bypasses standard shell commands to invoke sched_setaffinity, setpriority, and ioprio_set directly via the kernel interface.
• 🔋 Intelligent I/O Throttling: automatically lowers I/O priority for background logging and garbage collection tasks (f2fs_gc) to prevent disk contention.

🛠️ Technical Implementation

The optimizer uses a custom SyscallOptimizer class to apply changes safely and effectively:

1. High Priority System Tasks

Target: system_server, surfaceflinger, zygote, composer

• Action: Sets Nice -10 and locks to Performance Cores.
• Result: Instant app launches and smoother UI rendering.

2. Real-Time (RT) Latency Reduction

Target: kgsl_worker_thread (GPU), crtc_commit (Display), nvt_ts_work (Touch Input)

• Action: Applies SCHED_FIFO (Real-Time Scheduling) with Priority 50.
• Result: Eliminates micro-stutters in games and reduces input delay.

3. Background Suppression

Target: f2fs_gc, wlan_logging_th

• Action: Sets Nice 5, restricts to Efficiency Cores, and lowers I/O Class to 3.
• Result: Prevents background maintenance from slowing down your active app.

📊 Logging & Transparency

The module includes a thread-safe Logger with automatic rotation to ensure transparency without filling your storage.

• Main Log: /data/adb/modules/task_optimizer/logs/main.log
• Error Log: /data/adb/modules/task_optimizer/logs/error.log

📋 Requirements

• Root Access: Magisk, KernelSU, or APatch.
• Android Version: Android 8.0+ (Oreo and newer).
• Architecture: ARM64 (Snapdragon, MediaTek, Exynos, Tensor).

Note

Safety First: This module uses a Sanitizer class to validate PIDs and prevent regex injection. It is designed to be fail-safe; if a syscall fails, it logs the error and continues without crashing the system.
