Thomas Renninger of SuSE has announced cpupowerutils, a new free software project derived from cpufrequtils that is designed to offer much more thorough and advanced support for CPU usage/power monitoring and other performance statistics.
The cpupowerutils package takes all of the features from cpufrequtils, but goes beyond just monitoring CPU frequency switching (via Enhanced Intel SpeedStep Technology and AMD Cool 'n' Quiet) to better monitor deep sleep states, measure hidden Turbo Boost frequencies, and polling CPU/GPU power management support.
This new package also supports Intel's Nehalem and Sandy Bridge CPUs. On the AMD side there is Liano and Ontario (Fusion) monitoring support too.
