Are you saying it doesn't work on your machine or that you have found information to suggest that cpu scaling doesn't work at all in puppy (not true, where?)?
If you need help configuring cpu scaling a forum search for "frequency and scaling" reveals these amongst others
http://www.murga-linux.com/puppy/viewtopic.php?t=28443
http://www.murga-linux.com/puppy/viewtopic.php?t=12019
the instructions are quite straightforward and if you cannot get them to work on your machine I suggest you add a post on one of those threads.

If i go to the following path
cd /sys/devices/system/cpu/cpu0
in ubuntu linux i can find a directory named "cpufreq" that provide
information about the enabled CPU Scaling on the Machine.

In Puppy Linux this directory dont exist.
Its pretty clear that Puppy Linux dont support CPU scalling on my Mashine.
It runs my CPU in full Speed Modus.

In the following Path i can also not find any modules for CPU Scalling
like described in the above thread.
the Arch folder is mising.

cd /lib/modules/2.6/kernel/
cd /lib/modules/2.6.25/kernel/

What for CPU Scalling modules support Puppy Linux 4.0 native.

The Kernel 2.6.25 and 2.6 dont support any !
What about the other Kernels or better what for modules do you have in what for a path if you ran puppy linux in ram as a example?
Do you have the cpufreq directory ?

Yes, I do. Puppy does not load the modules needed by default, so there is no folder. You need to modprobe the correct driver for your CPU. See the first link Will posted for full directions.

As for the missing modules, this is because of Puppy's quirks. Most kernel modules are actually stored outside the normal filesystem, in the zdrv_xxx.sfs file. When you try to load one with modprobe, Puppy will first check to see if the module is in its normal place, and if so loads it. Otherwise, Puppy will mount the zdrv_xxx.sfs file and see if the module is in that. If it is, the module will be copied out into the normal filesystem and then loaded. From then on that module will always reside in your filesystem.

This will all change with 4.1, as I have abandoned the zdrv concept.
Now, more modules get detected and loaded automatically, including when hotplugging.

With the Puppy 4.1 Alpha Version the CPU isnnt getting any more such hot.
Running puppy more than 30 Minutes produce now a constantly maximal CPU Temperature Amount of 57 Celsius Degree.
The System Temperature Amount is maximal 44 Celsius Degree.

That is a reduction of more than 20 Celsius Degree !

One problem still exist and that is the CPU Scalling.
I am asking my self why Puppy 4.1 Alpha still dont support CPU Scalling.
The Fan is also running allways 100% in full mode.

For me Puppy still dont work very good with the Hardware at the Moment.
I am asking now my self what for a cpu speed do i have !
# ls

# cat */*

Hello Aitch !

Thank you very much for the Info !

I have found now why Puppy Linux 4.1 Alpha dont support CPU Scalling for my PC.

The File /etc/rc.local contain the Commands for enabling CPU Scalling.
If you look that file you would see that nearly everything is commented out there.
The only one modul that is loaded is
speedstep-centrino
all others will never be prooved !

With CPU Scalling now Puppy Linux 4.1 Alpha run my PC extremly Cool and the Noise is also nearly Zero :-))

The CPU Temperature Amount is also amazing cool.
Once Again the CPU Internal Temp is 10 Celsius Degree lesser.
# cat */*
<polling disabled>
state: ok
temperature: 49 C
<polling disabled>
state: ok
temperature: 41 C
Would Puppy Linux enable CPU Scalling as default for every CPU ?

I AGREE !
I NOTICED THE SAME HEAT ON MY PC !
PUPPY URGENTLY NEEDS CPU SCALING !
I noticed a big difference in my pc , with and without it.
Now with it, cooler and quieter. And the performances are not much different.

I suspect the 'on-demand' setting instead of 'performance' may suit some laptops & could be preferable - Barry?

For some strange Reason CPU Scalling dont work for me in the new Puppy Linux Release 4.3.

I have now the same Problems like before.

I dont know exactly what the problem is but everything works perfect in the new Linux Release just CPU Scalling make me drive crazy !

Hmmm does anybody have instructions how this can be solved now with the new Kernel ?

It looks like that the Kernel Modules are missing but i cant really imagine that as all the stuff that Barry has written in the Change Log works great but only the cpu scalling wont working.

Just wanted to tell you that i have solved the problem with the cpu scaling in the new release.

Now my Laptop is running very Cool and Quiet !
For some reason on my Laptop the modules aren't copied from the zdrive sfs. I needed them to copy extra from the ISO to pupsave file other wise it wouldn't work.

Here are my instructions if you have the same problem.

First don't use the small iso that is around 97 M.
Second use and download only the ISOS from ibiblio.
Third after the boot make sure that the modules are loaded
in puppy linux inside the folder "/lib/modules/kernel/arch/x86/cpu/..."
If you dont have any modules there copy them from the zdrive sfs on the cdrom.

After this just use the GUI Programm that was here posted and reboot.
# cat /proc/acpi/thermal_zone/THRC/*
0 - Active; 1 - Passive
<polling disabled>
state: ok
temperature: 49 C
critical (S5): 97 C
passive: 90 C: tc1=2 tc2=5 tsp=300 devices=CPU0
# cat /proc/acpi/thermal_zone/THRS/*
0 - Active; 1 - Passive
<polling disabled>
state: ok
temperature: 43 C
critical (S5): 80 C
passive: 75 C: tc1=2 tc2=5 tsp=300 devices=CPU0

broomdodger what for a output do you get if you execute this here ?

cat /sys/devices/system/cpu/cpu0/cpufreq/*


For me it output this here !

can you say me what for folders and files do you have inside

/sys/devices/system/cpu/

It looks like that your CPU Scalling is not working and your cpu is running in full speed.

The Temperature that you have posted in this case is the Motherboard Temperature and the CPU Temperature could in this case be around 80 to 95 Celsius Degree.

Depending on your CPU this can damage your CPU !

Puppy has been running for hours, no fans and feels cool.
I see no problem.
