There are several ways, as we have written several times here...
The easiest way is:
Code:
sudo nano /etc/init.d/ondemand
comment
Code:
echo -n ondemand > $CPUFREQ
and add line right below
Code:
echo -n performance > $CPUFREQ
To apply it without restart, after aforementioned changes, You could run
Code:
sudo /etc/init.d/ondemand stop
sudo /etc/init.d/ondemand start
or run a script
Code:
for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
do
[ -f $CPUFREQ ] || continue
echo -n performance > $CPUFREQ
done
with root privileges... I've made alias for that and I run it in /etc/rc.local since I do not want to change significantly vanilla install...
Or, simply, take ondemand out of that folder or take away its execute attribute...
As far as I know performance is a default state of scaling_governor... Until it is changed with ondemand script in /etc/init.d...
