what do you think? is this a save tool? i dont want to kill my cpu, but on the laptop it would be nice saving power with something like this --- now my intel p4m runs all the time on 2GHz

any success-story with something like this or simmilar things?

thanx in advance

I already have a package for this. I've been using it on my laptop for quite some time now.

dp · 2004-01-12 18:05:04

do you mind posting it in your TUR? ... i want to try saving power :-)

i can also built it, but it saves also 2-5 min of time using already built pkgs

thanx in advance --- i'm much nearer the solution

I'll get it up there after school... which is like 6 or 7 hours from now. If you don't want to wait, feel free to build it yourself.

ok mr cranky

dp · 2004-01-12 22:22:58

in the meantime i built it myself ... can be found in my TUR ...

but it seems it do not work:

i start it as root with autospeedstep start
but my cpu stays on 1998.52MHz the whole time of 10min@1.3% ... any ideas?

what does "cranky" mean?

I found I had to let it run for a while. I think it's not great at remembering what state it's in (fast or slow).

Another great program for auto-cpufreq manipulation is cpudfreqd (included in extra) & it's really customizable. However I'm having a hard time running it in 2.6.x kernels. When more than one progs (in my case cpufreqd & gkrellm) try to access /proc/acpi/battery/BAT1, acpid woes & I get 0% battery status, no matter if I run through ac adapter or battery. The only solution is restart.
In 2.4.x it works ok (with cpufreq patches).
Anyone else having such problems with 2.6.x kernels ?

using kernel 2.6.1

[root@Asteraceae damir]# cpufreqd -D
find_cpufreq_interface(): no cpufreq interface found.
Unable to find a cpufreq interface, please ensure to have cpufreq enabled in the running kernel.
Exiting.

any idea if i have to load a module or so?

You need to enable cpufreq in kernel, maybe that's why autospeedstep didn't run on your system in the first place.
For cpufreqd & 2.6.x you need to replace % lines in /etc/cpufreqd.conf with the actual cpu speed you want, btw. As example if your cpu is 2000 MHz, replace 66% with 1200. Just do the math .

cpufreqd works fine for me, in the 2.6 kernel, the only problem is it doesn't do what i want it to: it slows/speeds up based on battery life. something like autospeedstep would be good, but autospeedstep doesn't work, it spits out an error about no /proc/acpi/processor/CPU0/performance. I was looking at cpudynd, but that doesn't work either. Any other suggestions?

Which kernel version are u using, btw ?

is this not enabled in the 2.6.1 stock-kernel?

what do you do with 0%? what if this speed is not supported? i read that some p4m can only do some speeds longterm ... i dont want to break my cpu only to save a little battery

but thanx a lot for the answer; we are closer the solution i want

whatah · 2004-01-14 00:12:51

i am using kernel 2.6.0, but custom build.

zen_guerrilla · 2004-01-14 16:54:45

I switched to 2.6.1 (from 2.6.1-mm1) it works again . it seems like -mm kernels don't like cpufreqd...

Check the new cpudyn pkg. It's the best speedstep solution I've ever used (so far at least ).
