Edit: Now CM7 is stable, can we plz get custom kernels
Old:
Kernel Devs refrain from making custom kernels for CM7 because the CM team asked them not to, in the alpha stage of the development.
Today i asked Atinm if he could give the green light to the Devs, he replied:
atinm said:
Actually, we don't care if people run other kernels. We just say that we will not debug other people's kernels - so if you have bugs, you go to the kernel developer's threads. Same as on the other Galaxy phones. And there is more chance of your phone being unstable with each nightly when you are on a different kernel and we change the kernel.

I have maked one ...
I just saw it
Thnx
not quite the place to post this but party on
I had scaling issues with the stock kernel so i'm looking forward to this.
Great to see this.
I have 2questions.
1. Once we have these kernels will we be be able to flash files to enable Samsung stuff like Samsung dive, camera etc
2. Will new kernels be able to incorporate files from stock rom to fix the Bluetooth issue.
Thanks

CM 7.1 Stable has working bluetooth, and it wasn't a kernel issue, it was a driver source problem, Cyanogen either cracked it ahead of everyone else, or, got access to the missing source code, either way, winning like Charlie Sheen.
I have added my i9100 CyanogenMod 7.1 kernel with BLN support.
Details available here.

Correct, driver issues are not the same as the kernel.
I'd love to see some kernel supporting gpu oc-uv, it's a good feature for battery saving purposes imho.

Download stock CyanogenMod kernel
What is it?
It is a flashable ZIP containing zImage and wireless.ko extracted from cm-7-20120701-NIGHTLY-p500.
It is not compiled.
It is completely stock CyanogenMod kernel.
Who is it targeting?
Users of CyanogenMod (or CyanogenMod-based) ROMs that tried alternative kernels and now want to go back to the stock kernel.
Download optimized CyanogenMod kernel
Regular version | Extra version (with TUN and CIFS modules)http://www.mediafire.com/?efgv63eq614zn2ohttp://www.mediafire.com/?efgv63eq614zn2o
What is it?
It is exactly the same as CyanogenMod kernel, but compiled without some debug functionalities.
End users do not need them, and removing them makes the kernel smaller and may increase the speed a little bit.
This kernel should behave just like the CyanogenMod kernel and should have exactly the same functionalities. (in case it doesn't, please let me know )
Additional version with extra modules included - tun.ko and cifs.ko.
Who is it targeting?
Satisfied users of the stock CyanogenMod kernel that may want a little increase in speed and/or some functionality provided by the extra modules included, but do not like fancy modifications in kernels.
I need feedback and suggestions on the optimized kernels. Thanks in advance!
Nice one, could become handy to have a flashable stock CM kernel WITH wireless.ko.
Just a suggestion: You should enable the CONFIG_IKCONFIG option so that one can check which options you have configured in the kernel.
Also could not harm to have the tun.ko module as well (CONFIG_TUN), if needed for VPN connections.
Added versions with TUN and CIFS modules.
Flashed this, all seems good currently, great work
Also, this patch supposedly fix call reboots. Worth a try?

This time I disabled the "optimize for size" option and also checked another option to strip symbols.
When I have time I'll do a better research on that, but it's funny that all these changes in v01 and now v02 don't seem to change much in the benchmark I tested (AnTuTu Benchmark - only "CPU and memory", "2D graphics" and "3D graphics" tested).
In the worst case scenario I'll use this thread to publish only the latest stock CyanogenMod kernel to those who want to get it back.
Researched some more optimizations and built a new version. Now only one kernel already with the extra modules (TUN and CIFS). And it's getting harder to discover new optimizations.
Thx for your extra version with tun module, i flashed this kernel and openvpn work now with cyanogen rc1
Updated all three kernels. Enjoy!
Thanks, this is what I want.
I feel CM official kernel is the most stable and smooth!
After one hour use the optimized version, i feel that my phone has became smoother!
Sent from my LG-P500 using xda premium
This time I slightly broke my promise of not modifying the code of the optimized kernels.
I applied one change from LG's newest souces (V20A for LGP500H) that seems related to the behaviour of the phone when the screen is turned off (I'm not 100% sure).
https://github.com/yuripg1/lge-kernel-msm7x27/commit/ea2157b140ecf79530f33a214e38b48204c39e2b
I don't know exactly what problem it is supposed to fix, but it seemed safe to apply this patch to the kernel.
I also tried it by myself a little before releasing it and so far it's doing fine.
Sent from my LG-P500 using XDA
Once more, all three kernels up-to-date!
Thanks for keep working!

hi, all, i have a question about the BLN stuff! well, as i have read, tht not all kernels support BLN? where can i find those karnels then?? i know that saiyeh kernel do? how can i inegrate it with any Kernel so ill be free to install any one?
thks and sorrrrrrrrrrrry
You can't 'integrate it to any kernel'. The kernel has to support BLN & needs to have the necessary code to make it work, whether it does or not is up to the dev who makes the kernel. Unless you're planning to code your own kernel, you won't have any control over this. And if your next question is 'how do I make my own kernel ?' you either have a lot of research to do or you need to stick to using other people's kernels (I.E if you have to ask, you probably don't have the skills to do it).
Siyah supports BLN, and I'm fairly sure there are a couple of Siyah rip-offs on here that do as well. If you want to use BLN, read (do not post to the Siyah dev thread, post to the discussion thread if you must) the Siyah dev & discussion threads.

Noled is NOT bln, they are completely different.
BLN uses ur hardware led keys while noled simply turns on your screen and sticks an icon there.

Hi Folks,
This is my first post on XDA, though I have been using this excelent forum for a long while but never had a chance to post.
I want to share with all of you, ROM developers, the Kernel I have build for my own use for my GT-S5830i device, from Samsung Kernel Sources. Feel free to use it if you want.
THIS KERNEL IS ONLY FOR GT-S5830I, not for use in other devices. IT SHOULD WORK ON ALL ROMS, EVEN STOCK ROMS!!!!
Kernel Includes:
Freqs:
156 MHz
312 MHz
624 MHz
832 MHz
Governors:
Intellidemand
InteractiveX
SmartassV2
Conservative
bcm21553
Performance
I/O Schedulers
noop
deadline
cfq
vr
sio --> Got this one from Rafael Baugis Source. Thankyou Rafael, hope this is not an inconvenient.
Fatures:
Enabled Module Loading
Init.d Support
Improved kernel scripts (Many of them, i dont really know why Samsung is opensourcing such sources. I know this is a low cost phone, but...)
Swap support
Ramzswap support
Root --> Kernel is all ready rooted, su is in xbin as usual lol. Just need to download busybox and Superuser from Google Play.
Btw, Camera, Flash, Wifi etc etc etc... is working fine.
Optional boot logo (splash image) I have uploaded 2 kernels, one with Splash, one with no Splash. Splash img is attached below. Basically I modified param.lfs.
Filesystem Support
ext2, 3, 4
Msdos
VFAT
YAFFS2
JFFS2
AT THE MOMENT KERNELS CAN ONLY BE FLASHED BY ODIN, HAD NO TIME TO MAKE AN UPDATER SCRIPT.
I WONT EXPLAIN HOW TO FLASH WITH ODIN AS THERE ARE MANY MANY MANY TUTORIALS ON THIS TOPIC.

May be you will get CWM asking to reboot, please reboot, this only happens the first time.
Others:
Im not responsable if you brick your phone (its difficult to to do this if you have apropiate CWM and you have a complete backup of your system. If you dont have a backup, i think you are crazy trying kernels around the www).
Please dont ask me for OC, or adding more freqs, I have been trying this for many weeks with no success. MPU tables, opp, etc... just found nothing in the source code even seeking throug the asm script. May be I will spend some more time on this, but to be honest i am bored. 4 freqs for this "tiny machine" I think is ok. Remember Less Is Best.
Hope you enjoy it.
Thank you for downloading. And please dont donate, lol I do this for fun, but if you like it, please press the Thanks Button.
I will upload all sources to git as soon as possible, and if I have some time I will try to write a tutorial, just to have an other one on the web.
Special Thanks to:
Rafael Baugis, some of your sources helped me understanding the kernel, and I directly used your sio io sched source. Hope you dont mind.
Btw your kernel is really nice and complete. Difficult to add new features. YOU ARE A CRACK.

Hi all.
First of all i wanted to thankyou so much for the comments and the interest you have taken for, testing and benchmarking my kernel.
Please let me know any issues you find to keep on fixing and improving.
Please notice Rafaels kernel is uv for all freqs, mine has normal freqs.
Rafael as i assume is looking for batery performance vs performance, mine is based in performance vs batery.
What is best? Bothe of them depending on usage you want.
Rafael kernel has very good performance even with the uv. I dev the kernel slightly different to his one.
Why? Whats the meaning of having 2 kernels that are the same?
Be different my friend ))))
Thank you so much for the benchmark and taking your time and interest in testing. People like you motivate devs to keep on working

A rom is the combination of a kernel, middleware and system apps and included stuff. A kernel alone is the main part of any OS. It essentially manages the hardware, multitasking, drivers, memory management everything technical really is managed by the kernel. People often mistake linux as an operating system when in fact it is a kernel. it takes other things on top of the linux kernel to make an os, like for example Ubuntu or Android. You may want a custom kernel to keep the apps and features of your rom but improve cpu usage or memory management or to add features like overclocking.
