Hello,
currently tuning the powermanagement of my lappy.
First some hardware info.
CPU: Athlon II X2 P320
So if i use acpitool -c it tells me different settings for the two cores.
I'll look getting it posted in here.
CPU type : AMD Athlon(tm) II P320 Dual-Core Processor
Min/Max frequency : 800/800 MHz
Current frequency : 800 MHz
Frequency governor : powersave
Freq. scaling driver : powernow-k8
Cache size : 512 KB
Bogomips : 4190.74
Bogomips : 4191.07# of CPU's found : 2
Processor ID : 0
Bus mastering control : no
Power management : no
Throttling control : yes
Limit interface : yes
Active C-state : C0
C-states (incl. C0) : 1
T-state count : 8
Active T-state : T0Processor ID : 1
Bus mastering control : no
Power management : no
Throttling control : no
Limit interface : no
Active C-state : C0
C-states (incl. C0) : 0
T-state count : 96000 Active T-state : 96000
Powertop will not give any c-state related info.
Powernow_k8 is installed.
I use HPET as clocksource.
Have you some tips?
Greetings
Michael

Powertop is made by intel and it's for Intel processors, though it may give you some info about your cpu too.

I updated output from acpitool first post.
Powertop tells me c-state information is not available. Complete dump:

Suggestion: Enable Device Power Management by pressing the P key
Suggestion: Enable the CONFIG_PCIEASPM kernel configuration option.
PCI Link Powermanagement (ASPM) allows the hardware to go to low power mode
automatically when a PCI-E device is idle.
