Help with cpufreq please

[Aleph]

Hi friends,

I run PCLOS LXDE in a laptop and a netbook and I was able to set cpufreq "ondemand", but now I am not able in my desktop, a DELL Precisio 490. I was reading some post and trying to do something but without results.

Here is some info:

I run PCLOS LXDE in a laptop and a netbook and I was able to set cpufreq "ondemand", but now I am not able in my desktop, a DELL Precisio 490. I was reading some post and trying to do something but without results.

cpufreq-set -r -g performance -u 1200mhz


I put the above command in /etc/rc.d/rc.local and it sets the cpu
to run slightly faster than the bus.    Tried 0n-demand and
conservative but no-go.   If they work for you let me know how
you did it.

regards,

Hi Ferdes Fides,

what should I write for ondemande in /etc/rc.d/rc.local, only cpufreq-set -r -g ondemande -u ?

More ideas please?

[Yankee]

 ondemand in /etc/rc.d/rc.local   cpufreq-set -r -g ondemand


The above should work, if it does let me know, try -g conservative also,
on my machine it doesn't work.

Hi Ferdes Fides,

Thanks but I tried both and doesn't work 

Could be fantastic JUPITER for PCLOS but is not possible...

More ideas?

Thanks.

PCC (Configure your Computer) - System - Manage system services - make sure cpufreq is ticked to start at boot and is running.

More people should use the PCC Control Center, it solves most problems.

There are three packages in Synaptic for cpufreq, I only have the command
line package installed.   One is an initscript, it wouldn't hurt to install that and
use PCC and the /etc/sysconfig/cpufreq file to configure, and forget about
/etc/rc.d/rc.local to avoid start-up conflicts.   

If that works post back, I'd like to try -g conservative if it does.

FF

Hi Just17,

thanks but cpufreq is ticked at PCC and running....

Hi friends,

I was looking for cpufreq files at /sys/devices/system/cpu/ and really I have not files there!

My laptop has a lot, for example:


/sys/devices/system/cpu/cpufreq/ondemand:

- ignore_nice_load
- io_is_busy
- powersave_bias
- sampling_down_factor
- sampling_rate
- sampling_rate_max
- sampling_rate_min
- up_threshold

Something is wrong about cpufreq...

I was reading and more people have the same problem:

Just wondering if /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies may not be available in an updated 2010 install versus brand new 2011 install.

I have an HP Mini with 2 installs. One of updated 2010 and another test install of 2011.

I get on my updated 2010 install the following:

Code: [Select]

[root@localhost xxx]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies: No such file or directory

On going into the directory structure, I have a /sys/devices/system/cpu inside which there is "cpu0", "cpu1", "cpufreq", etc. Inside none of these I see the scaling_available_frequencies file.

I have both cpufreq-1.0-28pclos2010 and cpufrequtils-008-1pclos2010 accordiing to the rpm -qa|grep cpufreq


On the 2011 test install everything seems to work as suggested.

Even after using the frequencies reported by the 2011 install 2010 still shows no governor active by cpufreq-info.

Just reporting this for the possible difference.
-SS.

I agree, I tried all three programs in Synaptic this morning.    After rebooting
with each one several times the only one that responds is the one in rc.local,
the command line package.    And that with only the performance governor,
but does allow choice of speed with the -u option.   See Reply #1 for that.

Probably was made for an older kernel but just guessing about that.

@Aleph

Hi,

Can you run cpufreq-info in the terminal and post the result.    I think I may
have the right syntax for the cpufreq-set command to work.

Hi FF,

I posted the cpufreq-info result above, in the first post.

Hi FF,

I know but it looks like the drivers aren't working, wondered if they still aren't,
and I can't see your available frequencies.   What kind of processor is that ?

Anyway, this command works on my machine in rc.local.    I only have the cpufrequtils
package installed.   

On your machine :

#set cpu to correct frequency
cpufreq-set -c 0 -g conservative -d 800mhz -u 1600mhz
cpufreq-set -c 1 -g conservative -d 800mhz -u 1600mhz
cpufreq-set -c 2 -g conservative -d 800mhz -u 1600mhz
cpufreq-set -c 3 -g conservative -d 800mhz -u 1600mhz

Replace the 800mhz and 1600mhz with whatever is right for that
machine.   conservative starts low and goes to a high speed nicely,
ondemand actually starts high and works lower with cpu per cent
usage, the inverse of what I think is wanted.

So, put the above 4 commands at the bottom of rc.local, reboot,
run cpufreq-info, post that, and we can see this thing working if
the machine's cpu is recognizing the drivers it's supposed to.

regards,


FF

[Aleph]

Thanks FF, but doesn't works...

After copy and paste at rc.local this:

#set cpu to correct frequency
cpufreq-set -c 0 -g conservative -d 800mhz -u 2660mhz
cpufreq-set -c 1 -g conservative -d 800mhz -u 2660mhz
cpufreq-set -c 2 -g conservative -d 800mhz -u 2660mhz
cpufreq-set -c 3 -g conservative -d 800mhz -u 2660mhz


and reboot

About the proccesor: I can see at PCC

I have installed both cpufreq and cpufrequtils

[Yankee]

Thanks FF, but doesn't works...

Thanks, nice processor.   If you can install the 2.6.38.8-pclos3.bfs
kernel, reboot with that kernel, be sure everything is hooked up
beforehand, only other thing to try today.   The freq's probably
need to be adjusted once we get the driver to tell us what they are.

The new kernel still has one or two things about it.   My machine is
using the kernel above, one of the better kernels.

Have a good one.
