[KERNEL] HO!NO! Palace...

To avoid mess up in tread i decide to separate kernel from Rom.
This is going to be my Kernel palace
GB Kernel V1 include:
Overclock to max stable 1836 mhz
Under-volt all frequency
New low power level (Saves ~8ma at battery for low fps apps)
Add 5 more frequency table
Use readl_relaxed and writel_relaxed
Add interactive, smartassv2, lagfree governor
Implementation of 2-Phase OnDemand
P930 Gingerbread Kernel V1 (Work on Nitro HD and Bell Optimus LTE)
SU640 Gingerbread Kernel V1
LU6200 Gingerbread Kernel V1
P930 CM9 Kernel V4
Mirror
HO!NO! GitHub

Sweet thank you ! Cant wait for a CM9 hehe

Sir ,maybe you can improve your kernal for deep searching the cm9 kernal,hoping that would be a good resource for your ref.Meanwhile expecting your new ver Of your home-made kernal. keep up your job！

Can u change the charging animation of LU6200 when it's power off. The original one is really ugly. Thank you very much.

great job! Thanks very much.

THX 4 UR HARD WORK 4 OUR LU su!

Can't wait for CM9 kernal! Anyone see an improvement in battery life with the current kernals?

Thank you for all your work in main this phone one of the best out there

restored my phone to original att nitro hd rom, then flashed the corresponding kernel, wiped dalvik cache and rebooted.. now i dont have root access? any way to resolve this issue besides rerooting it.. the kernel shouldnt affect it right?

Your original nitro rom is maybe not rooted...
And no kernel does not change one thing about root.

i rooted the stock att nitro rom with super on click, then i made a backup and thats what ive been using, everytime i flash the corresponding kernel, it says i have no root access
Edit: I just rerooted it using super one click and everything works fine now, thanks for everything

Wasn't much better than on Bell Stock ROM the first days... but now after some days with tweaking and battery calibration the best battery life i have had so far!

init.d support
Any chance of adding init.d support? I have a set of sick tweaks that really promotes battery life and performance.
However, I can only install part of it (manually).

init.d support is already in my rom, this is why i don't see important to make it native in the first version.
In next release it will be native.

Thank you very much

Which ROM? I installed Kernelpan1c Nitro HD ROM and my wife is liking it very much (it's her phone). But she wants me to hook it up with my init.d scripts as she knows how much battery life and performance is improved. However, when I tried to add the init.d forlder manually, the phone soft bricked. I guess I should post this in the ROMs thread, but I am using this kernel, and as far as I knew, in order for init.d scripts to work, your kernel has to be compatable.

I love this kernel but I love to use cm9.
I know the developer here wants to wait cm9 to rc stage in order to make the kernel for cm9, I would like to ask if you can change your mind cos cm9 original kernel is so lagging. Pls help!

[Q] Processor running underclocked

Hi guys!
Since I am not allowed to post on Devs threads, I post my question here, hoping for maxio1998 to see it, or anyone related to the Jelly Sandwich Project
I own a Xperia Arc. I had it upgraded through PcCompanion, to ICS 4.0.4.
Since it was very laggy and I had little rom space available, I decided it was time for a change. I unlocked my bootloader, flashed the Advanced Stock Kernel via fastboot and flashed Jelly Sandwich 8.0 in CWM.
The situation is that my processor is not running at its full capacity, and I don't know if it's because of my kernel selection, or due to some tweaks in the custom rom I chose. The max frequency is 806 MHz.
I don't want to overclock, but having it working at its normal 1GHz would be preferred, since it has become to be laggy after a while (not as much as stock ICS, but still...)
Attached is a picture using CPU Spy +, to show the magnitude of the situation.
Is there another kernel that you would recommend?
Thanks in advance

I'm used Advanced Stock Kernel with stock firmware. Advanced Stock Kernel not supported overclock feature.
You can get "No-frills CPU Control" from google play and adjust Max. Clock freq. to 1.024 GHz.

Thanks for the piece of advice :highfive:
It seems it solved my problem. I fastbooted ArcKnight kernel and with that app I'm now able even to set it to overclock if required.

Kernels Help

Hi all,
I am fairly new to the whole flashing kernels thing. I was looking through the Android Development threads and I saw the KT kernel and the IX kernel. I wanted to flash either of these kernels just for the improved battery life (from stock). Here are some of my questions:
1. What is the main reason to flash a new kernel.
2. Once I flash the kernel, What is a governed and do I need to constantly change it or set values? (asking cause I see others doing this)
3. Once I flash, lets say I want to go back to stock kernel, how can I do this?
4. Will I really get better battery life, or is it just for those who currently have horrible battery life.
5. Would it speed up the phone by any chance, reduce any lag?
Thanks in advance for helping!

thats an amazing link thanks for posting that i was wondering the same thing
but can someone tell us noobs the main reason for updating your kernel like Kt's kernel?

Well, I personally use KT's kernel for a few reasons: his Ktoonservative governor which is great for battery life yet equally responsive, the ability to undervolt to maximize battery and a cool running device, and the ROW scheduler which offers me superior performance.

1. Some people flash a different kernel so they can overclock and under-volt. Also it may make the phone a bit snappier and get better battery life.
2. You don't need to constantly change the governor. You can try one for a few days and see how it goes. If youd like to experiment then you can try another to see if its any better/worse.
3. Depending on your ROM. Sometimes you can just boot in to recovery and re-flash the kernel you want. Again it depends on what kernel you flash to.
4.This is a tough one. Kernels act differently on each phone. You would need to try it out for yourself. When you flash a kernel it is suggested you give it a good 3 full battery cycles to really see how battery life is.
5. Yes, it may speed up the phone responsiveness a little. But again each phone reacts differently to each kernel.

The ability to control vibration, and the wide variety of i/o sched and govs is a main reason why I choose KT over any other kernel

still how can i revert
lets say i use kt and want to go back to stock kernel, how do i do this?

[Q] Underclock with stock kernel ?

Hi,
i know that it's not possible to undervolt without a custom kernel, but is it possible to underclock for example at 1300mhz with stock kernel and ROOT?
I'm with custom ROM / kernel and i get an uncredible battery life with undervolt (arround 9h screen on time) but i'm affraid of canceling the warranty with this stuff. I'm considering to go back stock ROM and buy an extended battery.

use root and apps setcpu (google play )

Kernel for stock kitkat 4.4.2?

Hi all, today I unlocked boot loader and rooted my nexus 7 2013 WiFi. At the moment I am sticking to stock ROM until I get more internet data from my ISP then I can flash a custom ROM.
Anyway what kernel would you recommended for stock KitKat 4.4.2 ROM in the mean time, or is it not worth changing and I'm better just waiting to flash custom ROM+kernel?
I was hoping for a more performance based one and would like to overclock both CPU and GPU, of course performance+battery contradict each other but if I could also have good-very good battery life and faster performance then even better.
Also what apps are you using for over clocking CPU/GPU?
Please suggest thanks

Best ROM/kernel threads are frowned upon at XDA.
As far as overclocking app, I use Tasker. I use it for setting the kernel tunables also.

I use elementalx with stock. Great performance and battery life.
