Sounds absolutely NoobLIKE , but I'd like to understand :
Does the Speed of ROM depends on Kernel ?
If so , which Kernel is fastest one ? (now im using Coutts , and IM pretty satisfied)
Thankss
yes, a different kernel can affect performance and it will also affect your maximum overclock, process scheduler (bfs or cfs), etc.
coutts kernel is a g00d option.

Hi there, I'm running Oxygen 2.1.6. on my Desire, and I'm trying to squeeze a little bit more out of my battery, and owning a Galaxy S as well, with the Galaxy, there are Kernels that Support OC/UV.
I'm wondering if there are any good kernels for Oxygen 2.1.6 (Gingerbread) that support OC/UV Thanks.
snq- 0.6 kernel supports oc/uv I think

I saw those, but I'm unfamiliar with how to flash these files. I'm used to having a zip file to either flash in CWM, or in Odin ( which the desire doesn't use)
The files in SNQ's are Z-images and .ko's...
I'm more familiar with the more n00b way of flashing kernels :X terribly sorry.

That is a Sense kernel. It is sometimes better not to write anything than to post an erroneous info. And furthermore, uv doesn't work properly with it.

What more do you want from Oxygen? Thalamus kernel supports both uvoc and is probably most efficient kernel as is.
Flash newest oxygen with newest kernel. And I am pretty sure, you will be very happy it. I tested many rom/kernel combinations with software like setcpu und low-voltage-scripts. With oxygen I only reduced maximal cpu frequeny to 768 mhz and min 245 mhz with the included cpu controller and do not get a worse battery life with other roms.
Nice, I'll give it a test. Thanks
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

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!

Hi guys! I just bought an Arc S, and it's totally awesome. BUT, even if I like the design of the stock ROM, it really can be improved. I always have around 60 mb of free RAM, and you can imagine the result
May I use doom kernel ( or any other kernel ) without flashing a new rom? Would I have improvements? Do I get more free ram?
Thanks in advance, I'm trying to learn everything I can about modding this phone, I had a Motorola and I spent the last months tweaking it, now it's time to start all over
If you've unlocked the bootloader, yes. Any kernel thread OP will advise what version of android the kernel will support, or if it's specifically for a certain rom(i.e. MIUI/CyanogenMod roms). Generally, custom kernels improve performance and add features not available in the stock rom such as call recording, various schedulers, overclocking and so on. Battery life tends to be better with the stock kernels though.
thanks! and specifically, if I want to stay ( for now ) with stock rom 2.3.4 which kernel would you suggest me to try? i'd like one with smartassv2 governor, i heard it's pretty good
Doomkernel is your best bet there, tbh.

Hello i want to overclock my arc s. Can anyone recommend me good kernel for the overclock procedure, and can anyone give me tutorial
Depends on your rom

Depends on the rom you use, because JB (ported) roms use a specific kernel, ICS an other one, GB an other.
So once you flash the right kernel(every custom kernel usually have OC, but u can read in the thread to be sure) , you can install No frills Cpu from market and set the cpu as you prefer. its really easy
Lupus and then setcpu or no frills cpu control
SETcpu or CPU master on android market should do the job
Most of the custom kernels have overclocking feature. But it can damage your hardware.You can use setcpu or no frills CPU to overclock your phone.
any overlocking can damage your HW use at own risk!
aaaand what profile is best for normal use ?

Hi,
I'm having a international Galaxy Note II GT-N7100 model and have currently 4.1.1 installed and rooted using ODIN method.
Build Number JRO03C.N7100XXALJ1. Baseband Version : N7100DXALIA. Kernel Version : 3.0.36-Perseus-alpha31.
I have installed the Perseus Kernel as shown in this thread. (Perseus-alpha31.2-n7100-CWM.zip).
1. It boosts the max cpu speed to 1800MHz. Will this decrease the CPU life in the long run? (This might be too early to comment though, taking into account the recent availability of this device, yes?)
2. Does anyone have a data on the battery drainage comparison (between this Perseus and Stock kernels)?
3. Where can I get the Stock 4.1.1 and 4.1.2 Kernels alone?
4. How to revert back to the stock kernel? Do I have to flash the complete stock rom? Or restoring from backup will do?
5. Can I bring back the max cpu speed down to 1600MHz using this Perseus Kernel?
Thanks for any information.

1. Yes it boost the cpu.. no it will not decrease cpu life WITH PROPER UNDERVOLTING in Stweaks
2.sorry I dont have data to show you but as ive experience ..my battery life increased... WITH PROPER UNDERVOLTING AGAIN in stweaks
3. Search the web
4.you can flash it and backup will also work
5. The maximum is 1600mhz in default .. you can overclock and underxloxk uaing STWEAKS
..
By the way STWEAKS is included when you flash perseus.. this is where you set what you want
n7100
omega rom v10 perseus kernel 31
hit thanks its free anyway

Thanks. What is the appropriate voltage (undervoltage) to be set for the stock 1600MHz speed? Is it the default value provided in the stweaks under CPU tab?
Thanks again.
