slack 11 + Core Duo T2600 + cpufreqd2.20 = variable frequency for 1 cpu only?

ppfundst · 10-09-2006, 10:11 AM

Hi there!

I am using a Dell m90 with a Intel 2600 (Intel Core Duo 2.1Ghz) processor. I installed cpufreqd-2.2.0 and cpufrequtils-002 on a brand new Slackware 11 with kernel 2.6.17.13 and I can monitor my CPUs (core duo=2 cpus) speed in KDE. All that is working great.

I can customize the rules in cpufreqd.conf and they got reconized well. Simple and excellent.

But.. wait, only ONE of the two processors gets is frequency changed by cpufreqd.

If I do:

Quote:

cpufreqd -D -V 7

(launching in foreground, maximum verbosity), I get upon event (for instance plugging AC cable):

...

Quote:

cpufreqd_loop : New Rule ("AC Rule"), applying.
cpufreqd_set_profile : Couldn't set profile "HPerf" set for cpu0
cpufreqd_loop : Cannot set policy, Rule unchanged ("none").

Yes! only cpu1 has its frequency changed! This is confirmed by the KDE system monitor applet and a

Quote:

cat /proc/cpuinfo

(the lines 'cpu Mhz' is different for each proc):

I am kind of puzzuled here; I do not know where to look to debug this...

Any ideas anyone?

Thanks,

I don't have a similar setup, but are you using the smp kernel?

ppfundst · 10-12-2006, 12:13 PM

yes, i am using an smp kernel:

from .config:

#
# Processor type and features

CONFIG_SMP=y
CONFIG_X86_PC=y

Thanks,
