This is a custom kernel for Optimus Black based on CM's Sniper kernel source.
It aims to continue with knzo's previous hard work (all credits go to him) but in a progressive way.
The name of the kernel contains two different 'fields':
- The date of the latest original lge-kernel-sniper included commit. You can check at https://github.com/CyanogenMod/lge-kernel-sniper if my last kernel includes the latest commits. In negative case, post here to ask for a new up to date recompilation.
- Huexxx's version of the kernel.
Use at your own risk.

FAQ:
Code:
Q. Do I need to wipe data?
A. No, never.
Q. Do I need to flash this if I flash a new CM update/nightly?
A. Yes. Everytime you flash a new CM version, you need to reflash this.
Q. I have xxxxx ROM. Can I flash this stuff?
A. This kernel is intended to flash it over CM7 ROMs. It won't work over stock ROMs.
Q. What can we expect from this?
A. Snappier, increased internet/market page loading, USB transfer rate, etc.
Q. How can I know if I flashed it correctly?
A. Go to About Phone in settings and you should see my nick around there.
Q. How can I change governor and set it on boot?
A. Go to Settings > CyanogenMod settings > performance > CPU Settings.
Q. How can I change I/O scheduler?
A. Don't change it for now... default one is Deadline and it works very well.
Q. What governor and/or scheduler is the best?
A. Take a look at [URL="http://forum.xda-developers.com/showthread.php?t=1242323"]this[/URL] amazing post from knzo. IMHO Smartass V2 (more performance) and InteractiveX (more battery saving) are the best. It seems that new Lazy governor is working so good at Nexus S community, so you can give it a try and comment.
Q. Where can I find the source for this?
A. [url]https://github.com/Huexxx/lge-kernel-sniper[/url]
--> It's under construction right now...
Make sure to read the FAQ before asking any questions.
Regards!
--- Reserved for future use ---
thanx for the great work!
Thanks a lot... flashing it right away.
The link to download it is enabled!
To say that by some reason it doesn't set interactiveX as default governor at boot... but you can set it (or another gov) on boot via Cyanogemod Settings, SetCPU or NoFrills.
Regards!
1st thing thx for ur work i like this kernel
2nd thing : i want u to tell wt is the best settings to set for saving battery and best performance (using profiles in setcpu for example :screen off) , governor and schedulers ?
i want the max battery.
ps: i have tried InteractiveX and i got 21xx points is that good ?
edit :
i'v noticed something ,i got i call and the screen didn't wake up so i'v pressed the wake up key to answer the call :S
Trying! Thanks!

otherwise nice work from you, thank you!!!
Have a nice day.
Hi all!
First of all, thanks again knzo.
I've seen the problem awaking the screen when incoming call. In my case is a lag more than a 'no-awake' problem. I'm looking into it.
Regards!
No lag for me, works fine everything.

Huexxx, try to compile with Codesourcery toolchain.
I compile with Linaro but I'm crazy and aim for performance whereas Codesourcery usually delivers the best stability.
I'm crazy too
Jokes apart, I tried with code sourcery with my first kernel compile attempt and it ended up in a bricked OB...
I'll try again in the future, but at the moment I'm goinf to stuck on Linaro 4.5 that runs guite well.
Thanks for the advice.
It is nice to read the conversation between Android Guru's...
and what can we do is just sit and waiting the updates... hehehe
+testing and report any bugs
is it applicable for stock ROMs?

It's intended for CM7 ROMs.
Maybe it can work with stock GINGERBREAD ROMs.
Don't use it with stock FROYO ROMs.
Regards.
Works a little bit faster then stock CM kernel
Quadrant score a little better too, thank you for your work.

Changelog of this update?
EDIT: Ooops, sorry, didn't see the (V0) and (V1)
Thanks..
what is the default max n min frequency in stock rom??? n governor n sio too??
default freq:- 100mhz-600mhz
default gover:- ondemand
default scheduler:- I think noop
Best kernel for battery performance and user experience (Lag free).
Please mention:
- Which ROM you are on and the kernel version
- CPU Governor if not default
- I/O Scheduler if not default
- If you manually UC/OC the CPU/GPU (mention frequency)
- If you manually adjust UV values then how low (if not kernel default)
PS: If any other Kernel apart from the Poll options then do write about it.
Let me start off
- Stock (rooted) with Franco R15
- Governor Interactive (default)
- I/O Deadline (default)
- No OC/UC done to CPU/GPU (default)
- No UV done (default)

Firstly, should NOT be in this section, maybe in General. Secondly, I'm pretty sure best ROM/kernel threads are not allowed on xda, or so I've been told.
This is not appropriate for a development section. Moved to General.
Please help in setting up this file in mini (in terms of performance)
You can give individual entries.
