AMD Cool 'n Quiet (powernow-k8 module)

sud_crow · 2005-03-04 23:44:59

Hi,

Im having a little problem on getting CnQ to work, here is whats going on>

[root@archcrow crow]# modprobe powernow_k8
FATAL: Error inserting powernow_k8 (/lib/modules/2.6.10-ARCH/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko): No such device
[root@archcrow crow]#

Im using the stock arch scsi kernel26.

Im missing something here? or the stock kernel has a problem with cool and quiet?

Just in case: I do have an Athlon64 and a motherboard supporting the feature, also its activated in the BIOS

sud_crow · 2005-03-06 00:15:59

Now one has a AMD64 with Cool and quiet running on Arch??

I found out that this package is requeried (or at least, thats what a lot of people say):
http://www.deater.net/john/powernowd.html

Its a deamon incharge of stepping the FSB.

I will be looking for more info later and post any updates. If i succesfully make this thing work i will post it to the wiki i guess.

There are a few ways of running cool-n-quiet... either with daemons, or just setting ondemand as governor in '/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor'
The stock arch kernel worked for me (kernel26-scsi 2.6.10-3), I don't remember that I had to install any extra packages., just loading the module worked.. (I don't have powernowd installed) what does 'dmesg | grep powernow' give you?

Check out:
http://gentoo-wiki.com/HOWTO_PowerNow!

sud_crow · 2005-03-08 04:38:34

the grep command is throwing zip (nothing) !.

here is:

[root@archcrow ~]# dmesg | grep powernow
[root@archcrow ~]#

Whats going on here?
according to the howto at Gentoo wiki, i should get a description of my processor powernow levels... heck.

Im using

[root@archcrow ~]# pacman -Qi kernel26-scsi

Also, i found out this:

[root@archcrow cpu0]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq: No such file or directory

The deepest i got is this:
/sys/devices/system/cpu/cpu0

There is no cpufreq dir, and ofcourse there is no scaling_cur_freq file.

Some tips?

You need to load these modules:
acpi_cpufreq and freq_table as well as powernow-k8

Algol · 2005-03-08 11:28:11

Im sorry that I cannot assist better, but are you *sure* that cool and quiet is activated in the BIOS? This all seems very familiar to me, but I've only set it up once, and then even in a very ad hoc manner.

I personally have cpufreq_ondemand loaded by rc.conf and freq_table is pulled in by auto (not in rc.conf), they shouldn't impact on your dmesg though... my dmesg | grep powernow gives:

powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.00.09e)
powernow-k8:    0 : fid 0xc (2000 MHz), vid 0x2 (1500 mV)
powernow-k8:    1 : fid 0xa (1800 MHz), vid 0x6 (1400 mV)
powernow-k8:    2 : fid 0x2 (1000 MHz), vid 0x12 (1100 mV)
powernow-k8: ph2 null fid transition 0xc

As a final resort, try updating your BIOS?
If I have time later I might experiment some to remember better.

I could load the "freq_table" module, but the "acpi_cpufreq" answered with the following error:

[root@archcrow crow]# modprobe acpi_cpufreq
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.10-ARCH/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device

Its the same as powernow-k8.

Dont understand whats wrong with this:
Yes the CnQ is enabled in BIOS, and YES, ACPI is also enabled (also tryed disabling it).

sud_crow · 2005-03-10 02:42:55

When i disable ACPI in the BIOS i get:

"BIOS error: No PSB was found"

or something like that...
I searched and its also related to the cool and quiet being disabled in the BIOS, but mine is enabled.

By the way, my motherboard is a Lanparty UT nforce3 250gb, im _not_ overclocking the CPU.

Regards.

Hi, I'm not sure if you've gotten this to work yet.
I have, and I though I'd post what I do.
I install cpufreqd package, and install powernowd from deaters site.
Then I add powernowd to the daemons line in rc.conf, powernow-k8 and cpufreq-userspace to the modules line. and check /proc/cpuinfo for results.
I also have an athlon64 btw...

let me know how it goes...

sud_crow · 2005-03-24 04:26:20

Hi,
thanks for the information, i havent gotten this to work, at least until now.

Im going to try your steps, and post the results at a later time (have to wait till end of month to buy my new HD and reinstall the system).

Thanks again!

sud_crow · 2006-08-22 03:18:43

I was looking for the governor file, to set the default mode, and i found this post, where i had this problem with cool and quiet and wanted to post the answer:

Bios Update... after a couple of months, DFI released a BIOS update where they fixed an incompatibility between certain memory brands and cool n quiet.

That's it... i lost so much time over this that i was quite angry they didn't at least post something about it before updating the bios.
