Hi there, quick question...
Do the newest kernels also include undervolting and conservative power setting? (and overclocking, but I don't understand why people even want that)
With newest kernels, I mean the kernels from http://oe.netripper.com/files/htcleo_autobuild/
Or should I use the kernel attached in http://forum.xda-developers.com/showthread.php?t=746997#
All this is answered in android development. Check ur builds thread. It will telk u which kernwl is being used and what is enabled. Im using shrubcrafts build. The included kernel has overclocking undervolting inckuded.

ok maybe I wasn't clear (blame it on the dutch! ;-)
Of course I know which kernel I'm using at the moment, indeed it's mentioned in the thread of the build.
However, I can't find any info on the activated options in the newest kernel (for example the kernel of the 24th august).
As far as I understand, someone started adding/changing some lines in some file and recomplied the kernel to have other options activated. I'm not sure, and want to know if recent autobuilds do have those options by default.
Please correct me if I'm wrong!

Hey guys,
I'm running CM7 on my Wildfire.
I'm still experimenting with android and I would like to know more about kernels.
So why should you flash a kernel?

I don't know, which kernels are available for wildfire, but in general you can gain many things. For example new or other drivers, security fixes, and/or mods, such as overclocking.

Hi
I'm fairly new to this also, what I would say is it's probably easier/quicker to search the forums first before posting it is very unlikely that your question hasn't already been asked and answered before.
Anyway ... kernels ... I have read it put simply as "code that allows the software to communicate with the hardware of your handset" so I guess it controls the actions of things like the wifi adapter and light/motion sensors and more importantly the CPU. CM7 already has a kernel that allows overclocking. There were some ROMs that you had to flash sepetate kernels on to achieve this.
Flashing different kernels to CM7 generally breaks some other function so in my opinion it's best to stick with the one currently built in unless a kernel is released to specifically fix a major bug.
If you look at the stickies topics in the wildfire sub-forum you will find a list of Rome, kernel s and radios with brief descriptions. Most kernel titles tell you what there main function is.

I see "[2.6.32.39]" nFinity" in a lot of people's Sigs. I have tried googling and I can't find any info on this Kernel at all.
Any info/help?
Edit - Scratch that, I just looked at my "About phone" and I'm on 2.6.32.40-nFinity [email protected] #1
Hey,
I see a lot of people using CM7 is this really the best one?
Also till how many mhz I can overclock on that one?
Yes Cm7 IS really great, in fact you can customize almost everything, and I really like that feature...
As for overclocking you can overclock I think to max of 768mhz(if I'm wrong somebody please correct me)...maybe you can a little bit more but I think it is kernel related...
Hope it helps,
Best regards

Irrespective of which ROM you choose, it is the kernel which allows (or disallows) you from Overclocking. Till date, there are 2 primary kernels which are available - HCDR.Kernel by Jacob and nFinity by arco, and both OC support upto 768MHz. (I think Deep-Knight has recently developed a new kernel for his ROM, which allows OC upto 600MHz)
Because of this, you can overclock your stock ROM also, if you so wish, by simply flashing a custom kernel.

Hi!
Which kernels can I use for original rom, if I want to overclock? HCDR, or Deep, or what? It will make the phone instable, or not?
Thank You!

You can use any. nFinity MC4 offers more features though, like Smartass Governor. It can be found here:
http://forum.xda-developers.com/showthread.php?t=995301
Else, you can use HCDR Kernel also, if you wish, and decide for yourself which suits you:

It shouldn't make the phone unstable at all. But, in any case, make a Nandroid Backup beforehand.
Thank You
Well M using hell fire .. Cm7 based ....
Which is stable till 729 Mhz overclock m using max 729 and min 490 (I guess)
Phone is Much faster than before and love playing angry birds
I read all the 2 posts, but Im not sure to change the original slow kernel, for a faster. All have some bugs, battery life, wifi, etc...
I dont know, which could be better for the stock rom, or which could be better than the original.
Anyway, I want to try one of that, but I dont know which.
How can I flash just the kernel? And also back up my programs with titanium, or mybackup?
It clears everything like the rom flashing?
Ok, I made it, its cool, and faster. Thanks for the help.
is the overclocking "app" in standard cm7? Or i must go to market or anything else to download it?

Its standard, under Settings > Cyanogenmod Settings > Performance Settings.
These question are about Nexus 7 tablet kernel.
Hi, I am wanting to build my own kernel but have questions, where would be the correct forum to post these question. They really don't pertain to any particulate kernel.
I am wanting to compile the 4.1 kernel and add low voltage and OC up to 1.5, adding a new governor would be nice but not really needed at this point in development
what files need to be edited?
what changes need to be made?
are all the modification made in mach-tegra?
I have looked at several githubs, they have way more changes then I want, I know there are kernels out there that do what I want, but I would like to learn the build process.
For right now i would like to know what files need to be changed to oc the kernel to 1.5 at a low voltage to conserver battery life. perhaps at some point add smartass governor.
thanks in advice for any help one can provide.
The Q&A forum would seem the most obvious.

That is correct (and to where this thread has been moved to) .
I've just flashed the latest version of paranoid android, loving it so far but was wondering about kernels and their benefits? What changes can you make and how exactly does it make the device any better?

Read the OPs of the kernel threads to get an idea of what they offer and decide which features you're looking for. Many offer the ability to over/underclock (not sure why you'd want to overclock when we're already running at 1.7, but to each his own I guess), others address the thermal throttling issues, but in general they usually include general improvements over the stock kernel. Make a backup and flash a few to see how they run.
I want to know if I need to install a custom rom or a custom kernel or a combination of both so that I can overclock my phone(1ghz single core). Please help. Why is everybody so silent here, so unwilling to answer a simple question as this. My fourth post of the same question.

Any custom ROM that comes packaged with an included kernel should allow you to overclock. AFAIK the oveclocking capability lies within the kernel (at least with Xperias this is the case) . At the least, a stock ROM with a custom kernel and a CPU/Performance app will give you overclocking options.
My suggestion though is to get a ROM like PAC, that comes with a kernel and the needed app to manage your CPU settings.

That is not fully correct.
Most PAC builds use the stock CM kernel. Our ROM offers performance settings to manage that, but they generally do not allow overclocking.
Some of us have additional builds with performance kernels built in. Not all of us though.
Your best approach would be to install PAC for your device then check your devices XDA thread for a popular performance kernel and flash that afterwords. The performance control will see the new CPU settings and you will then be able to configure it as you need.
DL an oc app, like CPU tuner or whatever..

Yes, you need a kernel with overclock support .
On Gs2 I use PAC and dorimanx kernel
On your phone you need to search for kernels and roms for your model
