Hardwarebedingte Grenzen der Taktfrequenz: 188 MHz - 1.50 GHz mögliche Taktfrequenzen: 188 MHz, 375 MHz, 563 MHz, 750 MHz, 938 MHz, 1.13 GHz, 1.31 GHz, 1.50 GHz mögliche Regler: userspace, performance momentane Taktik: die Frequenz soll innerhalb 188 MHz und 1.50 GHz. liegen. Der Regler "userspace" kann frei entscheiden, welche Taktfrequenz innerhalb dieser Grenze verwendet wird. momentane Taktfrequenz ist 188 MHz (verifiziert durch Nachfrage bei der Hardware).

That looks OK for me - basically. Are powernowd or cpudyn running, right?

this is not what we want ! so the change of frequency is not allowed as I understand

No, your system should adjust cpu frequency according to the needs. Services like powernowd can handle that for you. You can adjust the limits manually as well, see http://acpi.sourceforge.net/documentation/processor.html

If you do not want to use frequency scaling at all you just have to unload the cpu-frequency modules of course.

But let's check whether your system really adjusts frequency according to your needs. So just run cpuburn-in and take a look at the current processor frequency (running cpu-screen, cpufreq-info,... or just 'cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq'). Is it still at 188MHz is it increasing?

uname -a :

Linux amilopro 2.6.17-grml #1 SMP PREEMPT Tue Jul 25 10:57:35 CEST 2006 i686 GNU/Linux

Whover choose the smp for a single cpu lap top oris this double core ?

Hm?

The SMP-alternatives feature of recent kernels allows use of SMP enabled kernels on unicore systems, nothing to care about.
