Kernel module to undervolt Intel CPUs even with Secure Boot enabled
Kundervolt is a Linux kernel module that lets users apply voltage offsets to Intel CPU components through sysfs entries, even on systems with Secure Boot enabled. It supports DKMS for automatic rebuilding across kernel updates and provides simple read/write interfaces for CPU, GPU, cache, and other uncore parts. The tool is aimed at power‑savvy users and developers who want to reduce power consumption or heat without disabling Secure Boot. Compared to existing undervolt utilities, it integrates with the kernel and works out‑of‑the‑box on Secure Boot‑enabled machines.
