Processor Power Management

Introduction

Processor Power Management (PPM) is a key area within platform-level power management. Intel processors support many power management features. We want to make sure the Linux kernel leverages these power saving features for the end user.
PPM has multiple dimensions, such as:

Enhanced Intel SpeedStep® Technology (EIST)
Intel Enhanced Deeper Sleep

To use these features wisely, some enhancements must be made to the OS. The Linux kernel has some drivers and infrastructures in place, and there are more under development. This project will be a one-stop shop to find out everything you want to know about Intel PPM-related features, solutions, and enhancements that are being integrated into the Linux kernel.
