Ondemand governor only loads for core0 via rc.local.

I'm trying to get speedstep to work 100% before login, and there's only one problem left.

When I try to enable the ondemand governor in rc.local(
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor),
it only loads for cpu1 (core1).
If i run the same command after logging in it works just fine.
Anyone know why this doesn't work via rc.local? I really don't get it.

It's an Intel T7200 (merom) CPU.

Re: Ondemand governor only loads for core0 via rc.local.

Is your cpu driver module loaded? (i've got a core 2 duo, and i use acpi-cpufreq)
Install cpufrequtils and then run

cpufreq-set -g ondemand

instead of echoing it to the kernel.

btw, "cpufreq-info" to view the results.

Re: Ondemand governor only loads for core0 via rc.local.

It will still only work for one core.
Probably unsupported processor or something then..?

Tried adding:
cpufreq-set -g ondemand -c 0
cpufreq-set -g ondemand -c 1

to rc.local, same error as when I tried echoing the kernel. Core 0 uses the 'powersave' governor.
Strange thing is it works fine if i type the commands after logging in.

Re: Ondemand governor only loads for core0 via rc.local.

So it might be too early to do this in rc.local? strange...
Maybe you should try cpufreqd instead?

Re: Ondemand governor only loads for core0 via rc.local.

Same with cpufreqd too. rc.local runs last, after all the modules, daemons and others are loaded, right?

Re: Ondemand governor only loads for core0 via rc.local.

try to load it a little bit later by using "sleep". but so you have to load it in the background.

Re: Ondemand governor only loads for core0 via rc.local.

(sleep 30s;cpufreq-set -g ondemand -c 0;cpufreq-set -g ondemand -c 1)&

Are you sure gnome-powersave or klaptopdaemon isn't messing with your "manual" setup?
