How do i keep the min freq at 500mhz after phone call? It goes down to 250mhz after phone call...
@bigswed: are you sure that it really uses 125MHz? the telephone apps sets the "official" minimum to 125Mhz but the actual limits is determined by avoid_frequencies.
All of those ugly workarounds for the minimum and 600Mhz are due to bugs in the closed-source Nokia Telephone app. If we had access to its source we could make it much simpler...

yes, I did sudo gainroot
I plug the charger in, turn phone off then turn it on....the settings went back to default 250-600mhz.
This does not happen when I am not charging...

If the device is rebooted more than once within 5mins the configuration is not loaded
as it might have rebooted due to a crash. It's a feature and not bug.
But it next version there will be a better heuristic to determine whether there was crash.
did you perform the commands as root?

I am sistematically searching the lower voltages for my frequencies on Titan's kernel. When I undervolt too much, applications crash or the tablet freezes or reboots.
Is there a way I can determine which particular frequence made it fail? So that I can change more than one voltage instead that one by one. Thanks.

The easiest way is to set scaling_governor to userspace. Then, only setting scaling_setspeed changes the frequency.
It is important to note that writing to vdd1_opps_vsel does not actually change voltage level. The new levels only take when frequency is changed. Therefore if you want to change voltage level when using userspace governor, you should set a different frequency after writing to _vsel file.

You need to add 125 and 250 Mhz to the avoid_frequencies.

this will be supported in the next version of the kernel-power-settings package.
as a temporary workaround you can copy your configuration file to /etc/defaults/kernel-power and append the two lines to the file.
I have no /etc/defaults/kernel-power, but i have created a file in /etc/events.d with this:
Code:
start on started hildon-desktop exec /home/user/125 stop on starting shutdown

if I add 125000 and 250000 to avoid_frequencies, 125Mhz is actually enabled and used.
Maybe the patch author Matan has an idea why?

What is the min_freq and max_freq? Are 125 and 250 the only freqs in avoid_? There are paths when min_freq is used, ignoring avoid_freqs, but I thought they should not happen in normal operation. I am also not seeing this behaviour. Any tips on how to reproduce this behaviour?

@titan
Hi..
if i after a phone call my min_freq is 125mhz i have made i Desktop Command Execution Widget i can us. And i put "echo 500000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq | echo ""
in it. So now i have min_freq 500mhz... i donīt now any better way 4 it... until a fix is made.
