[MOD] IncrediControl - Easy control of voltages and kernel settings!

Please read this post through thoroughly before downloading.

This app allows you to control your CPU voltages with an easy to use interface. You can increase or decrease voltages (undervolt or overvolt) for all frequencies or fine tune voltages for each individual frequency.

! HTC DEVICES, currently only single core devices are supported !
! ROOT is Required !
! Kernel that supports HAVS or SVS voltage adjustment REQUIRED !

In addition, if you are an Incredikernel user, the app may also be used to toggle Incredikernel specific features on and off, namely USB fast charging and audio boost.

IncrediControl is now also available in the market:

NOTE: The settings in the general tab are only functional in kernels that have implemented the simple sysfs interfaces for usb fast charging and audio boost. If you toggle them, its not going to break anything, but they won't work and the app may crash. If you would like your kernel dev to implement the interfaces, please direct them to these two commits:

https://github.com/Chad0989/android_kernel_common/commit/41dc138bae23dc7582de72a4d9895aaa8e1f8b2d

NOTE2: It is a requirement of the HAVS adjustment that the kernel you are using has the HAVS sysfs interface implemented. If it does not, it will not work. Most non-stock gingerbread kernels have the HAVS adjustment. Very few sense kernels have the adjustment. I believe ziggy's latest is the only one that does.

NOTE3: Before using, please delete any boot scripts you may have in /etc/init.d that toggle any of the settings this app controls.

Restore script - use this if you went too low and find yourself in a boot loop. Flash through recovery:

Hmm. Wonder what this does, just magically appeared in my app this afternoon (not done yet, just a teaser).

Here's an icon I made in photoshop for the time being, so there won't have to be that plain android icon.

Undervolting with Incredicontrol

A month or so ago I had talked about a certain project I had taken on. I was determined to find the lowest stable undervolted settings for each specific cpu frequency in an effort to further maximize the phone’s battery life.
I began by setting my governor on the latest Incredikernel to performance, so that it would run at the maximum setting. I then set both the minimum and maximum governor frequencies identically. This would ensure that my system was only running at that exact frequency. Then, I ran a cpu stress test, along with Pandora actively streaming music, all the while either playing Angry Birds or jumping in and out of forum threads as a means to put the maximum demand on the cpu. If after a few minutes of this the phone continued to respond normally, I would then undervolt that particular frequency’s Max volt by -25 (save) within Incredicontrol. I continued with this process testing each undervolt dropping every few minutes until my phone became “unstable”. If I started getting app force closes, screen freezes, reboots, or an overall system lock up, I would know that I had undervolted too far. I did this testing with every frequency available and compiled a list of those specific undervolts.
Now, knowing that everyone’s Incredible is different, I added an additional +50 to my currently stable undervolt settings for the volt maximum’s to ensure that most (if not every user) would be able to benefit from my hard work without complications. If you feel like a dare devil however and want to further drop those max settings more, by all means you’re welcome to. However, I can not guarantee that you won’t have problems either immediately or hours later..
I do know that Chad compiled a max script himself but I do not know how he went about testing the frequencies. I do know that my phone was unable to handle his aggressive-script settings at the time. This is a modified version of one of his scripts.
If you currently use Incredicontrol, you will need to select the “Restore Defaults” button at the very bottom of the HAVS section and reboot your phone. This will eliminate any current “at boot” settings that will prevent my script from making the proper settings. After the reboot, go into Incredicontrol just to be sure the defaults have been restored. Now, reboot into recovery and flash the script. That’s it! I hope this works for you. Let me know what you think and if you notice any power saving difference. Since we’re dealing with a literal power control, there will be a power saving difference whether it be immediately noticeable or long term.
Please note that you are not required to run the Incredikernel for Incredicontrol to work. You just need to be on a Kernel that supports HAVS.

Thank you Chad for creating Incredicontrol and I hope at some point that you are given enough free time to further improve this excellent app.

EDIT: Some users are experiencing boot loops when trying to flash my script so since Incredicontrol IS a user controllable app, I can just post the frequencies if people are having problems with the script.
