No CPU C-States

[lewebster]

Hi,
not really a TOS Topic but i couldn't find a Subforum where this topic would fit.
Out of curuiosity i installed linux (Debian) on my F4-423.
To check whether i would be able to tune power consumption i installed and tested the "powertop" application.
This told me, that the CPU keeps hanging in C1 State, which means there are no power-saving states of the CPU.
Next i checked if the CPU is providing any power-saving states at all with

Code: Select all

root@mynas[~]# grep . /sys/devices/system/cpu/cpu0/cpuidle/state*/name

but that also told that only C1 state ist supported:

Code: Select all

/sys/devices/system/cpu/cpu0/cpuidle/state0/name:POLL
/sys/devices/system/cpu/cpu0/cpuidle/state1/name:C1

So does the Hardware really not provide any power-saving states?
That would be a really big bugger.

Greetings

Got it covered...
C-States weren't enabled in BIOS.
