 |
|
I need t a little help on setting up some things to save power on a core solo. I tried to follow the guide (worked on other systems) http://gentoo-wiki.com/HOWTO_CPU_Frequency_Scaling but this system does not have /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors. I am using the ACPI Processor P-States driver. Also on a related note, is there anything else I can do to reduce the amount of power being used in a workstation. (already tuned the hdparm for non scsi devices)
cpu specs as follows:
| Code: | cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 22
model name : Intel(R) Celeron(R) CPU 220 @ 1.20GHz
stepping : 1
cpu MHz : 1200.076
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 10
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss tm pbe nx lm constant_tsc arch_perfmon pebs bts pni monitor ds_cpl tm2 ssse3 cx16 xtpr lahf_lm
bogomips : 2401.22
clflush size : 64

Hello.
Maybe you don't have the correct settings in your kernel-configuration. The howto you posted uses a Core 2 Duo for example.
I have a Core Duo processor wich scales fine with Speedstep-Support compiled as a module (i dont use the P-States-thing).
For generic powersaving on Intel-Hardware i can advise http://www.lesswatts.org/ which is a collection of powersaving-tricks for linux on Intel-Hardware (provided by intel). |
