## What it is
A Linux daemon that prevents firmware-induced CPU throttling on Intel systems by periodically restoring package power limits (PL1/PL2) and temperature targets in MSR and MCHBAR registers. It supports AC/battery profiles, undervolting, IccMax, cTDP, and live throttling diagnostics.

## Use cases
- stop my intel laptop cpu from throttling
- fix cpu running below expected frequency on linux
- restore rapl power limits that firmware keeps resetting
- undervolt intel cpu on linux
- apply different power limits on ac vs battery
- diagnose why my cpu is throttling

## When to choose
- your Intel laptop or SFF system runs below expected frequencies due to firmware-applied conservative limits
- you want automatic re-application of power limits after suspend or power-source changes
- you need undervolting or IccMax overrides on supported Intel hardware

## When to avoid
- you have an AMD or non-Intel CPU
- you are not comfortable running a root daemon that writes directly to CPU registers
- your system is not actually throttling - verify first with s-tui or turbostat
