A high-performance, native systemless optimization engine for MediaTek devices with Mali GPUs

PerfMTK is an advanced Magisk / KernelSU / APatch module backed by an ultra-lightweight native C daemon (perfmtkd) and a rich CLI (perfmtk). Engineered specifically for MediaTek Dimensity and Helio platforms, it grants total, fine-grained control over CPU clusters, Mali GPUs, LPDDR memory buses, hardware touch digitizers, thermal curves, and storage subsystems.

With sub-millisecond profile transitions, an event-driven epoll reactor (< 3.0 MB RSS, 0.0% idle CPU), and deep multi-OEM compatibility, PerfMTK unlocks maximum gaming frame rates (120 FPS stable) and exceptional daily battery endurance.

• Universal SoC & Multi-OEM Support:
  • Auto-calibrated for all MediaTek CPU topologies: All-Big-Core (Dimensity 9400/9300), Tri-Cluster (Dimensity 9200/9000/8300), Dual-Cluster (Dimensity 8200/8100/7000, Helio G99/G95/G90T), and entry-level SoCs.
  • Universal compatibility verified across Xiaomi/POCO (HyperOS/MIUI), OnePlus/OPPO/Realme (ColorOS/OxygenOS), Vivo/iQOO (OriginOS/FuntouchOS), Samsung (One UI), Motorola (HelloUI/MyUX), Transsion (Infinix XOS/Tecno HiOS), and AOSP.
• Native C Engine & In-Memory Daemon (perfmtkd):
  • Event-driven epoll reactor running on only 2 threads with < 3.0 MB RSS and 0.0% idle CPU overhead.
  • In-memory configuration caching for sub-millisecond hardware switching latency.
  • 4-tier foreground app detection: LSPosed hook (PerfMTK-Hook), Netlink Process Connector (cn_proc), kernel cgroup.procs inotify, and adaptive debounced fallback.
• Hardware Touch & Digitizer Booster:
  • Native kernel-level touch sampling rate unlock (sustained 480Hz/500Hz) via direct digitizer ioctl (/dev/xiaomi-touch, /proc/touchpanel, /sys/class/touch/touch_dev, Samsung TSP).
  • Host-side THP Smooth filter integration to eliminate gesture jitter.
  • Touch input IRQs and dispatchers kept unpinned to Little cores, preventing frame preemption on Big cores and ensuring rock-solid 120 FPS in AAA games (PUBG Mobile, Wuthering Waves, Genshin Impact).
• Smart Fast Charge Bypass & Battery Care:
  • Dedicated gaming thermal bypass: charges at full speed without thermal throttle, keeping battery cells cool (31°C - 36°C even under sustained 120 FPS gaming loads).
  • Universal hardware capability probing: strictly distinguishes between genuine PMIC hardware bypass (Infinix, Samsung, Asus, Sony) and input suspension, preventing unintended battery discharge during gaming.
  • Automated battery safety guard with configurable emergency cutoff (45°C - 55°C, default 52°C).
  • Battery Care engine: configurable charge ceiling (50% - 100%, default 80%) to maximize lithium cell health over years.
• Sensor & IMU Latency Booster:
  • Isolated Sensor HAL and Xiaomi CIT Sensor to dedicated Little VIP cores (Cores 2-3) with nice -10 priority.
  • MediaTek SCP mailbox IRQ steering to eliminate gyroscope and touch jitter during high-load gaming.
• Advanced MediaTek Hardware Knobs:
  • DRAM DVFSRC LPDDR5X: Direct memory bus scaling with clocks up to 8533 MHz for memory-intensive titles.
  • Mali GPU & GED HAL: Dynamic frequency scaling and margin tuning for modern 5.x and 6.x kernels (dvfs_margin_value, gpu_boost_level).
  • MediaTek Game Boost Engine (GBE): Automated foreground game process acceleration and thermal headroom reserve.
  • FPSGO Sysfs: Adaptive tuning for /sys/kernel/fpsgo on Android 14, 15, and 16.
  • UFS Storage I/O Optimization: simple_ondemand clock governors and queue depth tuning for seamless open-world texture streaming.
• Full-Featured Terminal CLI & Interactive TUI (perfmtk):
  • Colorized dashboard, live telemetry, hardware inspection, profile editing, and backup/restore management.
• Companion App: Seamless integration with the PerfMTK-Manager Flutter companion app (Bento HUD, live thermal graphs, Quick Settings tiles).

• Processor: MediaTek SoC with a Mali GPU (Dimensity or Helio series).
• Android OS: Android 9.0 (Pie) up to Android 15 / 16.
• Linux Kernel: Version 4.14.x up to 6.1.x+.
• Root Manager: Magisk (v27+ recommended), KernelSU, or APatch.

1. Download the latest release .zip from the Releases page.
2. Flash the .zip in Magisk, KernelSU, or APatch.
3. Smart Installation Modes:
   • Express Mode (Recommended): Wait 10 seconds (or press [VOL-]) for an optimal automatic setup tuned to your RAM and SoC.
   • Custom Mode: Press [VOL+] within 10 seconds to selectively customize system.prop, post-fs-data.sh, or service.sh.
4. Reboot your device to apply all kernel and daemon settings.

The native daemon automatically switches profiles when apps enter the foreground:

1. (Optional but Recommended) Install the LSPosed framework.
2. Install the PerfMTK-Hook companion app.
3. Enable PerfMTK-Hook inside the LSPosed manager.
4. If LSPosed is not used, the daemon will seamlessly and automatically fall back to its internal kernel Netlink process connector and cgroup inotify engine with zero configuration required!
