Code:

echo 850000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo "125000 250000" > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/avoid_frequencies

Settings when device is in-active (i.e idle &. night times):
(freq range: 125 or 500MHz)

Code:

echo 500000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo "250000 550000 600000 700000 750000 805000 850000" > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/avoid_frequencies

Can keyboard slide ( slide GPIO 71) or lock (kb_lock GPIO 113) switch events be used as triggers for scripts? If yes, how?

Alarmd or fcron could be used to set these on/off, but I would like more dynamic way to set kernel tunings. Any ideas?
