From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This is the best summary I could come up with:

This patch series is about allowing Core Performance Boost to be controlled when using their modern AMD P-State driver on Zen 2/3/4 Linux systems.

Core Performance Boost is for allowing the AMD CPUs to operate within their turbo/boost frequency range.

Most users will want to keep Core Performance Boost (Turbo Core) enabled, but those wanting to dynamically reduce/limit their processor power consumption will be able to toggle the support with these pending driver patches.

Writing "1" to /sys/devices/system/cpu/amd_pstate/cpb_boost will enable Core Performance Boost (CPB) on supported Ryzen CPUs while a value of "0" will disable the feature.

These patches stem from this bug report requesting the CPU frequency / boost control support for the amd-pstate driver.

Those interested in this support can find the Core Performance Boost patches on the mailing list going through review.
