  Hell! \m/

  Pár év késéssel eljutott hozzám is, hogy a linux kernel már jó ideje támogatja az AMD Cool 'n' Quiet technológiáját. Kugli az én barátom, és megtaláltuk ezt a nagyszerű leírást, és felokosítottam a Debianomat.

  Ennyi a lényeg: apt-get install cpufrequtils sysfsutil

  És imhol az eredmény:

  Itt még nyugi van:
  peter@otthon:~$ cpufreq-info
  cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009
  Report errors and bugs to cpufreq@vger.kernel.org, please.
  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: 109 us.
  hardware limits: 1000 MHz - 2.00 GHz
  available frequency steps: 2.00 GHz, 1.80 GHz, 1000 MHz
  available cpufreq governors: userspace, conservative, powersave, ondemand, performance
  current policy: frequency should be within 1000 MHz and 2.00 GHz.
  The governor "ondemand" may decide which speed to use
  within this range.
  current CPU frequency is 1000 MHz.
  cpufreq stats: 2.00 GHz:3,66%, 1.80 GHz:1,51%, 1000 MHz:94,84% (402)

  Itt elkezdtem videót nézni:

  Itt lazult a dolog:
