The record

Purpose: ZenMaster configures power limits, thermal thresholds, VRM current limits, clocks, voltages, and Curve Optimizer offsets on AMD Zen processors through the System Management Unit.
Installation: It installs with pip as a pure Python package and requires Python 3.10 or later.
CPU support: The project says it supports 44 AMD Zen CPU families spanning Zen 1 through Zen 5/6, plus Hygon Dhyana.
Monitoring: It supports power-management table output, live per-core monitoring, raw binary table extraction, and JSON output.
Library: ZenMaster can also be imported as a typed Python library with hardware detection, SMU control, and SMN read/write functions.
Windows security: The project says its Windows backend uses the Microsoft-signed PawnIO driver, with restricted IOCTL dispatch and no arbitrary physical-memory mapping primitives.
Platforms: It supports Linux, Windows, and macOS on AMD Hackintosh systems; Intel processors are listed as unsupported.
Platform requirements: Linux use requires root privileges, Windows requires Administrator privileges, and macOS requires root privileges.
Hardware risk: The project warns that out-of-range voltage, current, or power settings can cause thermal throttling, system resets, or hardware instability.
License: PyPI lists the package license as GPL-3.0-only.
Related interface: The project links to ZenTune, a graphical frontend for Linux and macOS.
Support resources: The project links to documentation covering installation, CLI usage, tuning arguments, monitoring, the library API, troubleshooting, and FAQs.
