it will, but your mileage 'may' vary in terms of camera use/functionality, etc.

Nice work.
I just flashed it through rom manager. Will let you know how my battery does
So far seems quite quick.

Fair enough. I'll give it a try tomorrow and report back

Works fine here on my Desire Z. Thanks
Wifi, calling, 3G, camera, video.
Would love to see stuff like BFS, interactive/smartass scheduler and more intermediate speeds at the low end (if possible).
Might just try to build one myself.
*edit* Just noticed the -XTRA Nice.

Does it change the Wi-Fi Mac address like other overclocking kernel ?

No the MAC address doesnt get altered like one the other kernels. Most of the others have been fixed and dont do that anymore.

Nice work, pershoot! Everything seems to work together nicely. Hopefully, this might help with the battery life with the addition of my screen off profile clocked at 245...

Yes, you can. read the instructions

if you have setcpu set to on boot, flash back to stock, untick that option, then flash this kernel.
go up in 50/100 MHZ freqs and test at each spot. use ondemand cpu governor. tell me which freq(s) your device is having issues with.
thx.

Flashed over cm rc 2. Looks fine - glad this thing is finally getting undervolted. Cm kernel is not optimized enough.
However, this kernal has too many frquency sets. In setcpu most frequencies are at 0s total use tiime.

Stock O/C Kernel 1.7Ghz and CM/MIUI/GB O/C Kernel 1.8Ghz UPDATED 01/09 - Grankin01

First is an O/C kernel that I built from the HTC source. This kernel is stable and with the right profiles setup in setCPU has given me very good battery life. I'm giving coolbho3000 credit here as his post in the G2 forums is what helped me to do this. I am also acknowledging gr8gorilla who helped me several times through this process. Second is a kernel built from the latest CM kernel zource from zinx. It has proven to be very stable (after tweaking the voltages).
Now for the boring part ... If you choose to flash this you do it at your own risk. I am in no way, shape, or form responsible if you flash this and your phone turns into a paperweight. Once again, flash this at your own risk.
There, now that that is out of the way we can get on to the good stuff.
Make sure you choose the right kernel. The stock kernel will break your CM install if you flash it.

These kernels have no issue with video. If you are having trouble with youtube and such update your GB rom to one of the newest. There was a memory leak in the source for the rom itself that zinx has fixed. Thirty to Forty-Five minutes of straight youtube action and I had no problem at all.

I have packaged this into an update.zip format that you can flash through your custom recovery. Simply choose to install a zip from the sdcard and pick the update package to install it. It will install the wifi driver at the same time so you don't need to worry about that. Everything works with this kernel so far for me if you have any problems please post them and I'll see what I can do to fix them.
Remember that you hardware is not the same as your neighbor's so while he may be able to max the settings out and run stable your device may need to be set to a lower clock speed to run stable.
Source code for both kernels has been added to github. If you want to play around with them download source from here: https://github.com/grankin01
Happy Modding/Devving!

wow, thank you sir

I was just about to start testing kernels with Zinx's CM6 anyway. Looks like yours is first.
hmmm... could not run update.zip through clockworkmod. I was looking to extract the files and push them manually, however, I don't see a zImage file to push.

No luck with the miui rom. Cant get past the splash screen.

There isn't a zimage. I wrapped it all up in its own boot.img and then packaged it in the update.zip with the wifi module.

Not yet. It will work with the rom that you have installed right now though.

hey guys. im a noob to android. every other phone i have had has been winmo. i wanted to try this oc kernel because it seems easier to install than the gorilla one. however i ran into a problem when installing. i have a stock rom 2.2.1, perm rooted s=off, using clockwork recovery. i backed up my rom and flashed via rom manager. it then began to send me into a boot loop never getting past the first screen. just kept turning off and rebooting. soooooo i rebooted directly into clockwork and tried to do it from there and the same thing happened. so i restored my recovery and now everything is back to normal. can anyone point me in the right direction? i did notice that in clockwork it gave me two options to flash the kernel or to flash an update from the sd card. should i have flashed the update zip instead of the kernel or flash both.. sorry im a partial noob. i know how to use adb a lil and the emulator, this is the first thing i flashed on my phone and nearly had a heart attack from thinking i was bricked! any help is appreciated

Do you already have setCPU installed? Not everyone's phone will be able to reach the maximum speed without bootlooping or locking up. Just the nature of the beast. Try setting your speed down in setCPU (if you already have it installed) and turn set at boot off and then flashing and rebooting. Then you can test the speeds one by one to know what is working for you.
Edit: New kernel for CM and MIUI is nearly ready. 1.8Ghz with over 3200 on quadrant!!!

Only in the lower frequencies. The higher frequencies weren't stable running lower voltages.

Thanks OP. When you say the lower ranges, at which MHz did you not UV? Just curious. I am thinking of not OC'ing more than 1.4MHz and didnt know if I would get the UV benefit.

[KERNEL] Quattrimus Kernel

Announcing the Quattrimus kernel for the P930 and SU640
This is a drop-in replacement for the standard kernel in Android 4.2 based ROMs.
It will work with CM 10.1, AOKP 4.2, and any other custom ROMs.
Features
* Compiled with Linaro 4.6 2012.03
* Overclock to 1674MHz
* Entropy depletion patch
Instructions
* Download the zip file to your sdcard
* Boot into recovery
* Flash the zip file
* Reboot
Download
P930: kernel-p930-1.1.zip md5=0a39d52b638781c5a129d845a4f81e8e

Source
https://github.com/thebigq/lge-kernel-iproj
Changelog
Version 1.0
* Initial release
Version 1.1
* Compile with Linaro 4.6 to fix instability.

@devs: This kernel package only updates the kernel binary and modules using the same technique as AnyKernel. This is all done with the included updatebootimg binary, which is a modified version of the standard mkbootimg.
Usage should be obvious if you look at the edify script. It can update only the kernel, only the ramdisk, or both (but if you're doing both, you can just write a new boot.img directly and be done with it).
Feel free to extract the package and use the tools to cook your own kernels.

Sweet. Trying it now

tmdcode, can you build a kernel for lu6200 from vs920 cm source? We have cm 10.1 rom for lu6200 which ported from p930. But kernel from ported rom is not good enough for daily use.

@tdmcode
Do you get warnings when compiling with Linaro toolchain?
I dunno if these warnings affect the stability though compiled successfully.

P930 kernel works but SU640 kernel stucked at LG logo.
Moreover, where to get "kernel" file from compiled kernel? Is it zImage?
Thanks

The compiled kernel is arch/arm/boot/zImage. this is frequently renamed to "kernel".
The kernel I posted yesterday reboots when GPS turns on for P930 and VS920. Apparently it doesn't even boot on SU640. So I will be making a new one today.

[Q] I want to change ROMs, but I don't want to delete the way my kernel is configured

Yes, I configured my ROMs kernel (current one)... But I Don't want to wipe out the changes I made. I want to install a new ROM, which of course will install a completely new kernel.
So... What I did to my kernel:
Through Ubuntu Terminal ADB, I got the /proc/config.gz and edited my kernel to optimize it for my external USB adapter. (My phone: Galaxy s4 i9505, my ROM: CyanogenMod 10.1 stable)
Here's the ROM I want to install:
http://wccftech.com/update-galaxy-s4-i9505-to-android-4-4/
So if anyone could reply if they know how to do kernel building and configuring and could help me, it would be VERY MUCH appreciated In fact, I might donate!

Try trickster MOD kernel settings from the play store. Use the donate 1 to unlock the ability to save your kernel preferences. Just be sure to have the kernel you are running now in a zip file so you can flash it after your new ROM and then restore your settings through trickster mod. Good luck!!

No such thing as 'best ROM'. It all up to an user. However, I always like Slim. It bare minimum, I install only what I want to use, no unnecessary carp. As for Kernel, that depends on your final choice of ROM selection. Some ROM comes already with custom Kernel, if not obviously the choice of AOSP Kernels. If you do decide to stay with TouchWiz, there're custom Kernel for that too. Down the bottom line, you need to do some research first and see what ROM pleases you. But to honest, most are not that much of different. Only a handful would have a feature really stand out and no others have.
