not working ;/

What do you mean "not working"? You have to be a bit more specific. ;)
Did you compile it as a module?

BTW: It's not "my" patch, I just ported it to 2.6.24, it was made by someone else, originally for kernel 2.6.16. ;)

When you're using a kernel module you have to give the parameters to modprobe.
Code:
modprobe powernow-k8 freq_list=1800,1000 vcore_list=1100,900

from dmesg:

powernow-k8 and cpufreq was working for me until I overclocked my cpu (also changed voltage).

any1 could help ??

Are you sure, that you added the patch?

It works fine here (with 2.6.24 and 2.6.25-rc6).

And that you applied the correct patch. There's been two patches in this thread, other has only the vcore_list parameter and the other one has both.

There is only one for 2.6.24, afaik.

The patch seems to be disappeared. Could somebody post a new link for it? Is there any known version for the newest kernels?
Thank you very much !

Thank you very much !

I'm doing a server migration, should be back online, soon.
Just have to upload the data again.

Edit and that patch works still, so no need to post a new version yet.

Thank you very much! I was a little surprised by your quick answer. Please let us know, when and where the patch will be available again.

It's there already. Since it's only a tiny bit, I uploaded it first. ;)

Hm, using kernel 2.6.26 (basically vanilla), I've got the feeling, that the patch doesn't work anymore.
Can anyone confirm this?

(It shows, that it sets the voltages etc, there are no error messages, but the cpu temperature is at the default vid value (which is pretty hot on this subnotebook) and the fan blows like hell.)

On my system ( Socket 939, AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ ) the patch works fine with sys-kernel/gentoo-sources-2.6.26 and powernow-k8-vcore_list-2.6.24-git-v3.patch. xsensors shows correct, reduced voltage.

What cpu do you have - is powersave / ondemand governor enabled ?

What cpu do you have - is powersave / ondemand governor enabled ?

Turion X2 TL50 (1,6Ghz)
The governor is irrelevant, because you can't change the voltage of the lowest fid on that cpu (it is already at the lowest setting, 800mV).
The highest fid (there are only two for that cpu) is normally 1100mV, which gives me up to 90°C at full cpu usage.
(I will clean the fans and renew the thermal paste soon, that should drop the temperature a bit.)
I have been able to stable (not "QMC-stable", but "Spinhedge-stable") undervolt it at 925mV, which is also what I've set now and that gives me about 70-75°C at full cpu usage.
It shows, that it sets that:
Code:
powernow-k8: Found 1 AMD Turion(tm) 64 X2 Mobile Technology TL-50 processors (2 cpu cores) (version 2.20.00)
powernow-k8: Requested 1600MHz with 925mV
powernow-k8: Requested 800MHz with 800mV
powernow-k8:    0 : fid 0x8 (1600 MHz), vid 0x19
powernow-k8:    1 : fid 0x0 (800 MHz), vid 0x1e

But the temps are much too high for that to be real (it goes up to 90°C, so it's pretty much at default voltage).

Edit:
Afaik, there is a voltage sensor in the Notebook (MSI S271), but lm_sensor doesn't find it and so I can't read out the voltage.

Tried cpupowerd, but with the same results.
No errors, but no change at all, regarding the temperature.
BTW, here is a diff between 2.6.25 and 2.6.26 for the powernow-k8 files:

are some patch for new 2.6.30 kernel available . i still use the powernow-k8-vcore_list-2.6.24-git-v3.patch
and with 2.6.29 it´s work but not with .30

ok, I saved it as powernow-k8.diff, but then patching
Code:
cd /usr/src/linux
patch -p0 <powernow-k8.diff


gives me

it's 2.6.30-r4 tuxonice-sources, but i don't think tuxonice has anything to it?

anyone tried it, and succeeded?

I don't know but will this help:
http://www.linux-phc.org/forum/viewtopic.php?f=13&t=2

yeah, i already know about phc, but on my turnion it doesn't work well, and (what is more important) i don't want another small app loading everytime i boot, doing sth could be done without it...

this patch worked for me till 2.6.29...now, i'm running hotter ;-) 800Mhz ->+5C at full load, i even don't want to check at 1900Mhz ;P

(should also work for 2.6.30.4)

the lilo.conf syntax is now like the following (i compiled powernow-k8 NOT as a module!):
Code:

append="powernow-k8.freq_list=2900,2800,2600,2400,2200,2000,1000 powernow-k8.vcore_list=1230,1230,1230,1230,1180,1130,1100"

it´s doesn't work.

Perhaps you used the wrong -p or --strip option?

i did the diff in the directory of powernow-k8.c.

i used:
Code:

diff -Naur


So try this:
Code:

cd /usr/src/linux/arch/x86/kernel/cpu/cpufreq
