[Kernel] [PrimoU] 2013/05/14 Titanium-KISS

---

Hi

IMPORTANT: Before you continue reading!
At the moment this kernel is only for PrimoU devices
and NOT for PrimoC (CDMA) devices

IMPORTANT for CM users
If you want to use CM or a CM based ROM choose the correct kernel!
CM9 needs a different ramdisk.

With the permission from Adi_Pat I would like to announce my kernel build
All credits to this should go to Adi_Pat cause he did the hard work for
providing me with all I need. Therefore also the name has been
choosen to make this clearly visible.

This is just a first announcement.
I will upload the first image tonight

Principle #1:
Provide a kernel that is as close to stock as possible but provides
additional features that will improve functionality and/or performance

Some Q&A you might have
Q: what stands KISS for?
A: Keep It Simple, Stupid!
My aim is to provide a kernel that is 99.99% stock with just additional features
In the first build you will see
-OC (max 1.5)
-UV
-2 new goveners (lionheart, smartassV2)
-1 new scheduler (sio)

Q:will you provide a kernel with 2.0GHz?
A:No - since I want to provide a stable kernel and
my experiences showed that only using up to 1.5 is reliable

If you like to have higher frequencies you can
1) use Adi_Pats kernel
2) build your own kernel based on my changes and enable higher frequencies

Q:can I build my own kernel based on your changes?
A:sure. I will provide a patch file that can be applied on the original
sources provided from HTC

Q:how "close" is your kernel to stock?
A:actually if you dont use OC, UV and use govener=ondemand and
scheduler=deadline this IS stock kernel

Q:can you include feature "xy" in your build?
A:I will check and if it is not "against" principle #1 -Yes

Q:will you test your kernel builds?
A:yes. I will only provide images that have been tested to
1) boot without problems
2) have run through a basic test trying to include all important features
3) run some benchmarks to confirm that changes are not decreasing basic performance values

Q:how to install your kernel?
A:like titanium kernel
fastboot flash boot

I provide a complete folder with all downloads
please look at the following "naming conventions" for selecting
the correct image for your ROM!

Images containing "OC-UV" will have presets
Images containing "CM9" are for CM9
Images containing "CM10" are for CM10
All others are for stock (sense) ROMs

------------------------------------------------------------------------------------------------

The "key" e.g. 201207112231 is the build id.

Actually this is just the timestamp when the image has been created.
When you report issues with a build please also provide this id

You can also find this in

Settings -> About -> Software Information -> More -> Kernel Version

Just some notes on the govener and schedulers:
Stock kernel is using govener ondemand and scheduler deadline
To get more information about all of those see here
http://forum.xda-developers.com/show....php?t=1369817

You can get the stock kernel sources from here
http://www.htcdev.com/ (registration required)
Or from here http://www.mediafire.com/?o0uudb56oxawvaw

To create the KISS sources apply the patch supplied with each build

Other Downloads:

Note:
If you download save or edit those scripts on a windows host make sure that
you are not changing the line endings to be DOS "style" (CR/LF) since they will
not work on your device.

So before pushing them to the device check with e.g. notepad++ or any
other windows editor that the line endings are UNIX "style" (LF)

USB host scripts
Contains helper scripts for USB host mode

Flashable from recovery
http://www.mediafire.com/?cj1buyxvwteiyqq

Simply zip file
http://www.mediafire.com/?ao391v55e3f4h7r

Will print current settings like OC, UV and govener
Also works with Titanium kernel
http://www.mediafire.com/?emhetf9ctcb3l0g

01vdd script

with battery "friendly" govener tweaks
Also works with Titanium kernel
http://www.mediafire.com/?i79wlhjomh9bhyf

smartassV2-tune script
Allow setting smartassV2 govener tweaks for battery or performance
Call with argument "b" or "p"
