[APP][2.3+][NOV06,2012]Daemon Controller - a cpu daemon controller

DaemonController.apk by Sybregunne

Current Version: 4.3.2-beta1

Description:

A small android application that can control the daemons andrev_oc and virtuous_oc, directly set current cpu frequencies and modify cpu voltage in a per frequency basis.

Features

Supports android 2.3 (Froyo) and above (Tested with Gingerbread up to Jelly Bean)
Can configure andrev_oc and virtuous_oc
Allows switching between the two
Faster load times (average of 700ms)
Added core toggler hidden in the options menu as it is experimental at this stage. Works on tf101 using guevor kernel
Added IO scheduler setter hidden in options menu as well. (Experimental)
Supports 2 methods of undervolting
1. vdd_levels:echo " " > /vdd_levels
2. UV_mV_table:echo " ... " > /UV_mV_table where n is the number of available frequencies

Requirements

Android device (at least froyo)
Rooted device
Kernel with cpufreq module enabled
init.d scripting support (Optional)
Undervolting using any of the above-mentioned methods (Optional)

Install Guide

Download apk
Enable installing from unknown sources
Install normally
If you encountered a not installed error, uninstall old DaemonController use titatnium backup if necessary

FAQ

What does this app do?

Quote:

On its own it acts as a text editor for some of the files in /sys/devices/system/cpu/cpuX/cpufreq (where X is 0 to X depending on the number of cores in your device.
If using andrev_oc or virtuous_oc. This app will help you edit the configuration files for both. Enable you to start and stop the daemon.

What specific files in /sys/devices/system/cpu/cpuX/cpufreq does it modify?

Quote:

scaling_governor - Sets/displays the governor that is currently being used.
scaling_min_freq - Sets/displays the lower limit for the range of frequencies that cpufreq scaling will use.
scaling_max_freq - Sets/displays the upper limit for the range of frequencies that cpufreq scaling will use.

So What is this cpufreq scaling that you mentioned?

Quote:

cpufreq scaling is a linux kernel feature that controls devices' frequencies(speed) and governors(scaling) and many other features relating to cpu.
the word scaling refers to stepping-up or stepping down of cpu frequency based on core utilization.

So why should I modify these system settings?

Quote:

When device manufacturers designed their devices they attempt to strike a balance between a lot of factors like performance, stability, and battery life.
But users' needs varies, example one user might not play games at all and use their devices only for calling, texting and emailing.
So it would be rather useless for them to be running at max frequency that their devices can handle. This is where the app comes in.
You can set your frequencies and choose an appropriate governor for your use-case scenario.

Okay, what is the best governor to use?

Quote:

There are a lot of governors out there, the most common of which are ondemand, conservative, interactive, powersave, userspace and performance.
To make a short summary:
ondemand and performance prioritize higher frequency levels based on cpu-core usage.
conservative and powersave prioritize lower frequency levels based on cpu-core usage.
The difference is how they compute cpu-core usage and how much they step-up the frequency ladder. Although this can be fine-tuned which is a future feature for Daemon Controller.
So best governor? It is really up to you the user.

Do I need to use andrev_oc or virtuous_oc?

Quote:

andrev_oc and virtuous_oc allow the users to have 2 sets of values for the device. One for when the screen is on and the other when the screen is off.
So if you want to set a lower frequency and a less agressive governor when the screen is off then use the daemon. a little warning though, some ROMs have built in
scripts that modify frequency and governor during sleep and wake. I.E. Siyah & Dorimanx kernel.

This FAQ is still incomplete. I will be adding to this soon.

Will this work on jelly bean? I used to use this on my HTC desire.

I have tried on a galaxy s2 with a jb rom. So theoretically it should work.

here are my screenshots of the app

Question: can you check if you have the file "/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies"

I am trying to see if this will work... will attach sample app later

Edit try attachment below. I added a check file perm when reading files....
