LMKD‑PSI Activator is a Magisk module that switches LMKD to PSI mode to improve Android RAM handling, it offers dynamic ZRAM/swap management, adaptive swappiness, and live memory pressure tuning – install only if you have root and understand risks.
This post explains what LMKD‑PSI Activator is, why you might use it, and how to download, install, and use it safely. I’ll keep steps simple and practical so you can follow along even if you’re not an advanced user. The module is hosted on GitHub and is intended for rooted Android devices using Magisk.
Table of Contents
Features of LMKD‑PSI Activator
- Dynamic swappiness that adapts to CPU, memory, and IO pressure.
- Incremental ZRAM and swap management (multi‑ZRAM support and on‑demand swap).
- UFFD garbage collection and ZRAM deduplication when kernel supports them.
- YAML configuration for custom tuning and live memory pressure reporting.
Requirements
- Rooted Android device with Magisk installed.
- Kernel support for some advanced features (UFFD, ZRAM dedupe) for full benefits.
- Basic familiarity with Magisk modules and adb/terminal is recommended.
Download
Get the module from the official GitHub repository: [lululoid/LMKD-PSI-Activator on GitHub]. Use the Releases page to download stable builds.
Install
- Download the latest release ZIP from the repository Releases.
- Open Magisk Manager → Modules → Install from storage → select the ZIP.
- Reboot your device after installation. Some releases note that a reboot is required.
How to use
- Configuration is stored in Android/fmiop/config.yaml on internal storage; edit it to tune thresholds and swappiness.
- For logs, check Android/fmiop/ or use adb logcat -s fmiop -v brief to watch activity.
- Advanced users can inspect scripts like fmiop.sh in the repo to understand behavior.

Troubleshoot
- If apps are aggressively killed on MIUI, install compatibility fixes suggested in the README (for example, NoSwipeToKill).
- If the module causes instability, uninstall via Magisk and reboot. Check logs in Android/fmiop for clues.
FAQs
No. It requires root and some kernel features for full functionality; test carefully and keep backups.
Use the GitHub Issues page or the Releases notes for guidance and changelogs.
