I'm tracking some really elusive bug and I'd be truly grateful, if you could check how things are on your boxes.

Please execute (as root)

modprobe powernow-k8
echo 0 >> /sys/devices/system/cpu/cpu1/online
echo 1 >> /sys/devices/system/cpu/cpu1/online

and then check whether /sys/devices/system/cpu/cpu1/cpufreq exists.

Please post your CPU/MB model as well.

Thanks!

-edit-

I forgot to mention that powernow-k8 module has to be loaded.

I have Athlon 64 3000+ on a DFI lanparty nf2 MB.
I don't have any *cpu1 directory, only cpu0

lucke · 2006-09-28 07:58:45

That's why I'm asking X2 (dual core) users for assistance ;-)

Thanks anyway.

lucke · 2006-09-30 16:26:40

I don't believe no one uses X2 on Arch.

appeared for me when i inserted the module. didn't need to echo it

That's the thing - when I put one core down (which happens when suspending) and then up, cpufreq isn't active on that core anymore.

Thanks for response, but would be nice if you could confirm that cpufreq dir exists _after_ echoing 0 and then 1.

enderst · 2006-09-30 16:49:46

1 remains, 0 goes away

lucke · 2006-09-30 17:00:41

So, cpufreq dir goes away when you first put the core down (echo 0) and then reappears when you put it up (echo 1)?

Well, many thanks for input. I really don't know why it doesn't work on my box. Could be a hardware problem, then. I've been fighting with it for over a month, trying to pinpoint the culprit ;-)

Would be nice if some guy with X2 on Asus A8N-E could input.

enderst · 2006-09-30 17:30:56

cpufreq dir does not go away, /sys/devices/system/cpu/cpu0/online goes away

lucke · 2006-09-30 18:10:16

O_o

Firstly, I don't think cpu0 should have online file in it (at least in my case only cpu1 does). How is it in your case, actually?

Eh, I think I'm going crazy.

Mr.Elendig · 2006-10-03 15:28:44

I can't even load the module

After a fresh boot on a X2 system. with Cool'N'Quiet enabled in BIOS?

Master Beef · 2006-10-04 19:04:03

everything works fine for me.
Athlon FX X2 4200+ Asus A8N-E.

lucke · 2006-10-04 19:11:39

*sigh*

That's one mightily elusive bug.

Thanks, Master Beef. At least I know A8N-E probably isn't the culprit.

Mr.Elendig · 2006-10-25 15:31:25

upgraded kernel, and now i can load the powernow:
results:
[root@bigbox oh]# modprobe powernow-k8
[root@bigbox oh]# cat /sys/devices/system/cpu/cpu1/cpufreq
cat: /sys/devices/system/cpu/cpu1/cpufreq: Is a directory
[root@bigbox oh]# echo 0 >> /sys/devices/system/cpu/cpu1/online
[root@bigbox oh]# cat /sys/devices/system/cpu/cpu1/cpufreq
cat: /sys/devices/system/cpu/cpu1/cpufreq: No such file or directory
[root@bigbox oh]# echo 1 >> /sys/devices/system/cpu/cpu1/online
[root@bigbox oh]# cat /sys/devices/system/cpu/cpu1/cpufreq
cat: /sys/devices/system/cpu/cpu1/cpufreq: No such file or directory

Oh, and I can't reload the powernow-k8 module

[root@bigbox oh]# modprobe -r powernow-k8
[root@bigbox oh]# modprobe powernow-k8
FATAL: Error inserting powernow_k8 (/lib/modules/2.6.18-ARCH/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko): No such device

But ofcause, my brain ain't functioning 100% atm, so there is probably a simple explanation for that.

Mr Green · 2006-10-25 15:33:00

dumb question what does /proc/cpuinfo show?

Wooohoo, someone with the same issue as me. At least I know I'm not alone.

What's your motherboard, Elendig?
