Throttled

This tool was originally developed to fix Linux CPU throttling issues affecting Lenovo T480 / T480s / X1C6. The CPU package power limit (PL1/2) is forced to a value of 44 W (29 W on battery) and the temperature trip point to 95 'C (85 'C on battery) by overriding default values in MSR and MCHBAR every 5 seconds (30 on battery) to block the Embedded Controller from resetting these values to default. On systems where the EC doesn't reset the values (ex: ASUS Zenbook UX430UNR), the power limit can be altered by using the official intel_rapl driver.

Features

The tool supports undervolting the CPU by configuring voltage offsets for CPU, cache, GPU, System Agent and Analog I/O planes
The tool now supports overriding the IccMax by configuring the maximum allowed current for CPU
On a lot of modern CPUs from Intel one can configure the TDP up or down based on predefined profiles
Arch Linux community package
