Hello,
It seems kernel 2.6.10 did some good things to my computer so I decided to check if the speedstepping works.
I'm working on a gateway200x
I have acpi in my modules and acpid in my deamons.
The problem is I can't check my current CPU freq. If I power the computer while it's connectec to AC and I check the cpu MHZ in /proc/cpuinfo I see my 14000. If I turn it on while it's on battery I see 6000.
Which is what I want.
But if I plug/unplug it during work /proc/cpuinfo stays the same. Is there a correct way to check the current frequency?
Thank you
Grey

try the /sys filesystem.... i believe it'd be /sys/cpu0/something

cat /proc/cpuinfo only displays specs i think, not the real temporary values.
I recognize that while theory and practice are, in theory, the same, they are, in practice, different. -Mark Mitchell

You probably want to check the values that are in /proc/acpi instead.

You must look inside this directory:
/sys/devices/system/cpu/cpu0/cpufreq/
You will find your current frequency, the scaling governor, the avaliable governors...
As root write:
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
to see the CPU frequency.
LB06: I don't know if it is normal to have only 64KB of cache memory. I think centrino has at least 1024 KB.

i think you need a BIOS upgrade (for the cache thingy =])
All you got to do, is tell the story right...

This could be because it is only reading the L1 cache, and not the L2, I am not sure though.
