HTC Evo 4G Freedom-v0.9.5 Kernel

Here is the start of something that I hope is fun. My first time messing with kernels, I have also been an AOSP fanboy, until the latest HTC Sense OTA. For some reason I get awesome battery with the stock kernel. So knowing that, I thought it would be nice to add some tweaks to a sense kernel and see how good the battery can really get. I don't have a website to promote, so I use mediafire for downloads, if you have a mirror please let me know.

Changelog || Source Code || Screenshots

New 0.9.5 Aggressive Only!
All Downloads
Note: That right above is indeed a download link!

You can find all the changes I make in the changelog above. Please let me know if there are any issues. You can follow me on twitter which is in my sig or on google+ in my sig as well.

Thank you everyone! I have no idea who "created" smartass, so I have no idea who to thank. Please help me with that.

About Freedom Kernel

Below is a little snippet of the script I wrote, I will have more info about the versions at a later time. For now, this is pretty self explanatory.

Code:

lithid@MPDI:~/Development/Htc-Sense-Freedom-Kernel$ ./build-it.sh --help
Usage: build-it.sh [OPTION]
Here is a list of available options:
-F    | Build Stock Freedom
-L    | Build Less Freedom -75mv
-M    | Build More Freedom -125mv
-A    | Build Aggresive Freedom -175mv
-ALL    | Build all versions

Notice to anyone using this kernel:

If you are seeing battery drain with the latest release its because the voltages for anything over .998 Ghz is now at its stock voltage, which was causing issues being under volted. So if you are overclocked your battery will die faster. If you want speed you will have to pay the piper. This won't change. That's just how it is. Its unstable to under volt the OC frequencies.

Freedom Kernel Config

Here is the freedom kernel config that will be included into the v0.9.5+. This config is simple and easy. Just edit what you want. No need for an application or scripts running in the background. This solution is great because it allows custom user control, without the need to know a program, or have loop scripts running.
This config lives on the sdcard @ /sdcard/FREEDOM-CONFIG/config. Just mount the sdcard/or use a text editor from the market. Make your changes and reboot. Thats it!

Code:

Awesome! Any plans on adding SBC? I think that's what a lot of people are waiting for (me included).

WHAT IS SMARTASS?
Smartass is a “new” governor I wrote for my HTC Hero. I wrote it to optimize battery life without comprising performance.

Wipe Cache and Dalvik-cache, flash the kernel, reboot, enjoy.

...real simple . go into recovery and do a nandroid back up first,, then whne done wipe cache and dalvik, then flash kernel.. thats it

Hey lithid, I know nothing about creating custom kernels, but I remember previous ones had less havs and more havs for better battery. Would you know anything about this?
The smartass setting makes things pretty quick, thanks for creating this.

I am looking into adding havs support w/ sysfs. This would make is possible to edit your own havs settings using a tool like vipermod, or other voltage editors.

Sweet goodness, thx man
