From my knowlege a Kernel is what shares info between the operating system and cpu...its like the bridge between the two (correct me if im wrong guys, don't flame me lol)and to what kernel you should be using is all you're choice, every kernel has a different build...some for performance, some specific to a certain distro of linux...so do some research and pick the one which is recommended for the rom you're running.

Thanks for the info. What do you install first, the rom our the kernel?

Definitely decide what ROM you want to use first, then find out which kernels are supported. For example, I am on DamageControl 3.2.3 and running the DC Netarchy OC Kernel because it was tweaked specifically for the ROM.

Does it matter in which order you install the ROM and kernel though?

Most if not ALL ROMS include a kernel. So if you flash a different kernel, then flash the ROM, the different kernel you flashed will be lost. So in short; ROM then different kernel.

most of the roms contain a stock kernel. the custom kernels for most of the roms are actually forks from the GoDmOdE community kernel. most of the time netarchy and the others kernel devs do beta testing of their changes before informing me to pull them in to the mainline kernel. this takes all the bugs and repeated commits out of the mainline and works them out before they are pulled in.

Thank you.

CM 6.0.1 - Should I bother using a different kernel?

Keep the kernel that came with CyanogenMod 6.0.1 or use a different one, that is the question.
Please discuss below.

He didn't mention custom, he said the one that came with it. I'm actually thinking the same question. Anyone?
ya... name one other one that works with CM6??????

If none of the other kernels work, I suppose that answers my question. I was under the impression that you could use any kernel with any rom.

Nooooo. Most kernels will list ROMs they were tested on to determine compatibility and stability...
For instance, KingxKlick's kernels are specifically meant for 2.2 Sense ROMs, no others i.e. CM6...
I mean you can always try kernels I guess. I mean that's what nandroid is for, right
There is no other kernel that works with CM6.

[Q] Kernel Manager Pro - How to Overclock

I was just wondering if it's advisable to use Kernel Manager to flash custom kernels to overclock and if so, which kernel is the most stable and suggested for use? If not, can someone redirect me to a overclocking guide? Thanks!
It all depends on which ROM you are using (sense based or aosp).
Depends on what rom you're running. I personally don't have a use for kernel manager as I just grab the zips and flash them in recovery. Kernel manager is a tool just like rom manager, both offer users friendly methods of flashing (kernels, roms) etc or as I would say (for the noobs lol). Id rather not use an app for something i am capable of doing myself in recovery. Not bashing it just saying I personally don't need it. What rom are you running?

The free one will work fine too. Let us know some more info and we'll help you more.

I agree with ya on doing everything through recovery and grabbing your own zips.... but I remember when I first got my evo and rooted it, all this flashing, kernels, roms etc. was very intimidating (I'm a dopey chef and don't know tons about computers) and rom manager let me learn the ropes with out being scared I was going to turn my phone into a brick. I think rom manager and kernel manager (if that's what its called)are good for noobs. THEN..... when you get your feet wet and are confident with the whole thing.......GO XDA CRAZY!
I had no idea I could flash kernels through recovery too. But I'm on 2.3.3 (TMartinPPC EvoGingerSense v0.1).
Ahhhh, unless I missed something, I don't think any of the current Kernels play nice with the leaked update.

You are correct. No kernels yet for 2.3 sense but they do have some for 2.3 aosp. To flash a kernel in recovery just grab the zip place on sdcard like you would a rom, flash it, then wipe dalvik-cache, reboot and enjoy!

So what AOSP ROMs are compatible with what kernels?

There's tons of 2.3 aosp roms out there. I use cm7 #39 with the tiamat 3.3.7 kernel or the savaged zen 2.0 kernel. Those are the main 2 kernels people run on 2.3 aosp. Savagez Zen also has their own aosp rom which includes more control of their SZ kernel.

So basically any 2.3 AOSP ROM can work with those two kernels? And those two kernels are the ones used for overclocking?

Correct! Cm7 has built in features that let you adjust your frequencies and governor settings; so does savagez zen. For the ones that don't just look for setcpu.

The built in CM7 Kernel will allow overclocking to 1113 also.
Ahhh I see. Thanks again guys!

Any kernels you can use with the stock rom?

Can the stock rom be overclocked.
Can anyone help?

Yup just flash a custom kernel that can be OCED like ziggys kernel or chads kernel (dont use the latest one just use the 12/23/202-sense kernel)

never mind i just remembered that ziggy had taken all his kernels down until final release. You'll have to use chad's incredikernel sense kernel dont try the newer ones read whats in huge letters in the OP
i like hydro kernals ssuv
I've been using the Incredikernel for a few days now, and seems like it's pretty nice.

Stock kernel for HTC Desire?

Does anyone have a link for a stock kernel which would be compatible with my set up (in sig)?
I want to try a stock rom to see if I can get sky go to work on my desire as it can't be used on a rooted device, others have had success by changing their kernel.
Thanks in advance.
As far as I know you are stuck with thalamus' kernel if you are running Oxygen rom.

So it is. But imho that's not really a disadvantage: _thalamus' kernel is a good one.

I agree. He does come to me as somewhat arrogant but I got to admit the dude haz teh skillz.
Could I try a stock rom and kernel and then go back to my current set up or would I then be unrooted?
Well you can "try" and flash the kernel I am using I suppose... but as far as I know it will break your camera and probably some other stuff I don't know. Do a nandbackup just in case you want to be adventurous. You only wanna find out if Sky would work if you change kernels first right?

Yes that's right, it has to be a stock kernel as sky do a check on the kernel before the stream loads apparently.
Well if it's stock kernel that it requires, then you have to use the official Sense based rom and kernel. All sense roms here uses a custom kernel so you are out of luck. You can't use Sense kernel on AOSP roms anyway.
OK cheers
I will have to wait for techy people to hack the sky go app then.
Depending on how Sky works, you can try and flash one those sense based roms. Who knows, the custom kernel they have might work. I have the impression that they are all based on the original sense kernel anyway. Or just wait for someone to hack the app.

[REPO] Touchwiz 4.4 kernel

For kernel devs I've uploaded the stock ND8 source to github for ease of cloning.
Branch master (should link you to that one anyway)
https://github.com/cnexus/kernel_d2spr_tw_44/tree/master
Check branch stock_modded for random goodies like disabling selinux in the kernel and removing some attempts by samsung to prevent root.

Biggest thing worth mentioning here...3.4 KERNEL

Is that a 3.4 kernel?

Does this mean you're going to give your GPE rom another try since you have a 3.4 kernel now?
