Nobody tries to do that. Best regards, Mateusz Viste

[snipped] question: what's your requirement for this? i ask because the atom consumes so little power to begin with, why bother?

Indeed, I didn't expressed (or expressed very poorly) the "what I want" point, focusing mostly on "how I want to do it" :) In fact, the need is simply to make my HP Mini system to be the coolest possible, to 1) extend the battery ontime as much as possible and 2) make the internal fan not working all the time (currently, the fan starts few minutes after system's power on, and then never stops). To me, acpi-cpufreq (along with the ondemand governor) seemed to be the best way to achieve this. ...but I might be wrong. :-P I am using acpi-cpufreq on some other of my systems, with great results (much cooler CPUs), that's why it was my very first reflex.

That's what cpufreq is about. have you considered "cpufreq_ondemand"? it's geared for improved power control and temp control modprobe cpufreq_ondemand -- "Life is like a buffet; it's not good but there's plenty of it." <<< Remove YOURSHOES to email me >>> |
