[Q] Kernels?

Ok... can someone please tell me what HAVS, CFS and SVS means?

HAVS - no idea
CFS - http://en.wikipedia.org/wiki/Completely_Fair_Scheduler
SVS - no idea

lol... i guess google is my friend
HAVS (Hybrid Adaptive Voltage Scaling) What this does is provide SUPERIOR BATTERY
Really? Anyone else use these kernels? Whats the risk, is it risky like flashing a Radio?

No, only thing is some undervolted kennels might not be stable so always nandroid before changing kernel.

Brill - I have some Nandroid backups, so if anything goes wrong the recovery will still work, and I can restore... excellent. Thought so

AOSP Kernel for SENSE ROM?
http://forum.xda-developers.com/wiki/index.php?title=FAQ#Kernel
here's a link with "all" neccesary informations
--------------------------------------------------------------
i would like to add a new question in this thread:
is it possible to use an AOSP Kernel like: http://forum.xda-developers.com/showthread.php?t=893484
with my SENSE-ROM ? (currently using ReflexTSense http://forum.xda-developers.com/showthread.php?t=791315 )
thx

No, at least I know that way. You have to use a Sense kernel with a sense ROM, like this to run without problems.

so there's no option to use newer Kernels with Sense-ROM's ..
thx for the information

Sorry to break into your thread, but does it work the other way round? I mean, is it possible to use a Sense kernel with an AOSP rom?

sense with asop and the other way
i tride som ASOP Kernel with my SensHD Rom and it worked "booting
i found a flickerning screen but it worked; i refalashed a sense kernel
i think that the other "Way" should also work with some "issues"
greetings..
ps: i somewhere on thos forum found a discussion between two ROM-Programmers about using ASOP Kernel in Sense roms.
As far as i remember they both found the conclusion that sense-kernel are using differetn Graphicdrivers so that a asop kernel never will run "full" with a sense-rom but the ASOP Kernel COULD be modded in "future"

[Q] Overclock Question

Hi. I have a S-Off, perm rooted T-Mobile G2 and would like to use this method to overclock my phone:http://theunlockr.com/2010/12/14/ho...ted-s-off-t-mobile-mytouch-4g-or-t-mobile-g2/
Q1: Is it recommended?
Q2: It requires me to use a custom ROM, which I do not want to. Is there an "original" rom that has ADB Remounting which I can use instead?
Thanks in advance.

I'm not able to view the method you've posted from where I'm at right now, but I can tell you that the most stable, "permanent" overclocking experience I ever found when on stock rom is CM's BaconBits (which includes an overclocking kernel among other things) used in conjunction with SetCPU.
you will need Clockworkmod recovery installed on your phone to flash the baconbits zip. I'm guessing you already have this - if not, you just need to install Rom Manager and you will be able to flash cwm recovery through the app.
from there, all you need to do is install setCPU (it's free here on XDA - just search for it) and use it to set your clock speeds.
easy as pie method for overclocking on stock rom.. and my guess is that it will be more stable than anything you get from theunlockr - it seems to me most of their tutorials are a bit outdated for the vision.

Download ROM Manager and use it to download Pershoot's kernel.

you can try pershoot's as well, but I will say that it did not play nice with my G2's stock froyo rom. this was a few months ago though so maybe there has been a remedy and it's working swimmingly now.
if you get pershoot's kernel to work, I would recommend it over baconbits as pershoot is constantly updating and improving it.

Just to clarify.... You need to change your kernel to overclock not your rom. A lot of roms include an overclocked kernel but that doesnt mean you cant flash a kernel with your stock rom. Make sure you set up a heat profile with setcpu so you dont fry your phone.

Thanks guys for all your help.
I went with a more simple solution, and flashed CM7.
Now it looks as nice as the original and has 1.5GHz overclock.
Do I need to set heat profiles for CM7 or the stable release will take care of it?

What is a kernal

I am running the mik ROM 3.0 and I am not sure what a custom kernal is or how to flash a kernal is it the same as a rom?? How do I apply a kernal while using my ROM?? I have searched the forums and couldn't find an answer plz help me out thanx

A custom kernel lets you overclock and under clock. So you can actually choose what speed you want your phone to run. First download the kernel put it on the root of your sdcard (not in any folders) go to recovery wipe cache and dalvik cache then flash kernel then reboot
Sent from my PC36100 using XDA App

The kernel controls certain hardware functions such as process scheduling, CPU clock speeds and voltages, frames per second, battery charge/discharge behaviors, etc. The best possible "layman's" analogy that I can think of is that a kernel is similar to hardware drivers that you install onto a computer. The drivers tell your system how to use whatever hardware components you've got installed.
There are a few rules with kernels though. You can't just download any kernel, flash it, and go on your way.
1. Sense kernels ONLY work with Sense ROMs. AOSP kernels ONLY work with AOSP ROMs.
2. Don't use a HAVS kernel if you're using setcpu.
3. Don't bother flashing a kernel if you don't know what a kernel is or are incapable of reading the sticky, at the top of this forum, whose sole purpose is to explain everything about kernels. Because chances are you're just going to screw up your phone.
Threads about kernels are one of the most common questions on this site, next to battery life issues and ROM preferences. Use the search feature. I guarantee there are a million threads that have already answered your question. If all else fails.....Google.
Edit: kernels do more than just letting you overclock your cpu like evo4gnoob said. If you don't know what a kernel is then you probably shouldn't be overclocking your phone anyway. And no, overclocking your Evolution is not like overclocking your computer. Again, you're likely to damage your phone if you just go and start tinkering without a clue as to what you're actually doing.

[Q] Kernel for Stock Plus v3.01?

Hello, now I have the rom: Stock Plus v3.01, but I want to know if there are any kernel support this rom that allows me to overclock the phone and add more modifications for performance and the like.

Look for gingertiny kernel, or incredikernel. You can find both here http://www.incredikernel.com/?page_id=10, along with incredicontrol and app for tweaking kernel settings.

thanks for your answer! one last question which of the 2 is more stable gingertiny kernel or incredikernel? Both are installed recovery is true?

I only use gingertiny and havent tried incredikernel, but i hear others say there using it all the time. And yes they are flashed thru recovery.

Help here!

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.

hey dude....

if u install a custom rom it is obvious that a custom kernel will get installed automatically...
any way there is a app called setCpu that helps u overclocking the phone required your phone is rooted...
u can also use "seeder" an app that tries to add smothness to the kernel....

You would only require a custom kernel for your purposes.

Custom ROMs can be built with stock kernels so that's not always true.

The question asked did not specify a specific ROM. The question was what would be required to perform OC. What is required is a custom kernel that allows tweaking. Telling someone if they install a custom ROM they automatically get a custom kernel is misinformation.

plzzz be clear

i think u need to read the question properly..
he is asking about custom kernel and rom as well....
if u use stock kernel then it would work only with aosp based roms with only minor changes not the change that allows processor tweaking...
and one more thing the stock kernels used to be part of custom roms of gingerbread ...
