You can check which cpu governor is running (here it shows the case of
'ondemand'):
[EMAIL PROTECTED] cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
ondemand
Also, check that the drivers are loaded, using
[EMAIL PROTECTED] lsmod | grep cpu
cpufreq_powersave 1920 0
cpufreq_ondemand 6556 1
You can switch governors by echoing the governor into
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
, performance gives 100% cpu scale
, ondemand gives well... on demand cpu scale
, powersave gives the lowest cpu scale possible
, you can use the following script:
[EMAIL PROTECTED] cat /etc/init.d/cpufreq
#!/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
case "${1}" in
start|demand)
logger "Enabling ondemand cpu frequency"
echo ondemand >
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
;;
powersave)
logger "Enabling powersave cpu frequency"
echo powersave >
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
;;
stop|performance)
logger "Enabling performance cpu frequency"
echo performance >
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
;;
*)
echo "Usage: ${0} {start|demand|powersave|performance|stop}"
exit 1
;;
esac
The ACPI patch can be found at http://acpi.sourceforge.net/download.html
, download the patch which fits the correct kernel number; in my experience,
the newer the better.
