Title:
scaling_max_freq always on lowest
Status in “linux” package in Ubuntu:
Expired
Bug description:
Hi,
I have HP EliteBook 8440p with quadcore CPU, using Ubuntu 12.04 and
Gnome-Shell 3 using two bateries.
I noticed following:
When batery comes under certain available power and/or when laptop is on
power adapter and bateries are charging, until bateries are over 85% (not sure
correct number), I can't change scaling_max_freq to maximum number.
It stays on lowest possible freq and can't be changed.
When bateries are over 85%, I can change this file.
vi says : "E667: Fsync failed" when I try to save the chages.
echo 2534000 > scaling_max_freq doesn't say anything, it just silently does
nothing.
I am using performance governor.
This is my rc.local which I use to set frequencies and governour:
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor
echo 2534000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo 2534000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
echo 2534000 > /sys/devices/system/cpu/cpu2/cpufreq/scaling_max_freq
echo 2534000 > /sys/devices/system/cpu/cpu3/cpufreq/scaling_max_freq
And here is my /etc/sysfs.conf
devices/system/cpu/cpu0/cpufreq/scaling_governor = performance
devices/system/cpu/cpu1/cpufreq/scaling_governor = performance
devices/system/cpu/cpu2/cpufreq/scaling_governor = performance
devices/system/cpu/cpu3/cpufreq/scaling_governor = performance
devices/system/cpu/cpu0/cpufreq/scaling_max_freq = 2534000
devices/system/cpu/cpu1/cpufreq/scaling_max_freq = 2534000
devices/system/cpu/cpu2/cpufreq/scaling_max_freq = 2534000
devices/system/cpu/cpu3/cpufreq/scaling_max_freq = 2534000
/etc/init.d/ondemand is disabled.
I changed all this files, because I got performance problems (cpu on maximum
when using firefox and laptop was draging).
Then I noticed that I can set cpu (with indicator-cpufreq) to more then
minimum freq, so I found out that my scaling_max_freq is also on lowest
frequency.
