    Phoronix: A New CPU, Power Monitoring Utility

    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...

    Shouldn't it be 's/Liano/Llano'?

    It puts out some nice info:

    ./cpupower frequency-info
    analyzing CPU 0:
      driver: powernow-k8
      CPUs which run at the same hardware frequency: 0
      CPUs which need to have their frequency coordinated by software: 0
      maximum transition latency: 8.0 us.
      hardware limits: 800 MHz - 3.20 GHz
      available frequency steps: 3.20 GHz, 2.40 GHz, 1.60 GHz, 800 MHz
      available cpufreq governors: conservative, userspace, powersave, ondemand, performance
      current policy: frequency should be within 800 MHz and 3.20 GHz.
                      The governor "ondemand" may decide which speed to use
                      within this range.
      current CPU frequency is 3.20 GHz (asserted by call to hardware).
      boost state support: 
        Supported: yes
        Active: yes
        Boost States: 1
        Total States: 5
        Pstate-Pb0: 3600MHz (boost state)
        Pstate-P0:  3200MHz
        Pstate-P1:  2400MHz
        Pstate-P2:  1600MHz
        Pstate-P3:  800MHz

    Linux should have a very general hardware information (monitoring) API instead of these projects.

    Now that I have that out, the cpu/gpu utility is a good idea I'm fully in favor of it.
