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:
Intel Low Power Mode Daemon v0.0.4 has been released with "LPMD" being the open-source daemon for optimize active idle power for modern Core hybrid CPUs under Linux that sport a combination of the E and P cores.
The Intel LPMD selects the most power efficient CPUs based on the detected CPU topology or a user configuration file.
Then based on system utilization and other hints it will put the system into a low-power mode when applicable by engaging the most power efficient CPU cores and disabling the higher power/performance cores when not needed.
This Low Power Mode Daemon so far hasn't been too commonly used by Linux distributions or popular with Intel Linux users, but alas still in its early days and only today crossing the v0.0.4 milestone.
With the support for multiple low-power states, Intel LPMD can define multiple states based on EPP / EPB / ITMT settings, IRQ migration, and task migration.
I've been meaning to run some Intel LPMD power/performance impact benchmarks and now with this new release is a great time to do so.
