About
This kernel is built from Samsung's official sources (available on github thanks to supercurio). It's clean, fast and it aims to be stable.
Please note that this kernel won't root your device automatically but you will be able to remount /system as r/w and then push Superuser apk and binary.
This kernel should work with any european ROM.
Features
ClockworkMod recovery 4.0.0.8
Stable Linux kernel 2.6.35.x (currently .9)
Deadline I/O scheduler tweaked for flash usage
SLQB slab allocator
/system/etc/init.d scripts support
"Insecure" mode
Some other tweaks and improvements

great news
is the lastest Linux Kernel not 2.6.39.2?

Can i use this kernel for the cognition 1.07
Nice release.
In your git repo, you posted that this kernel build includes BacklightNotification. Has this been confirmed working by you with BLN control?

It won't work with BLN Control app because, as we can't modify liblights, we need to manage blinking at kernel-level.
I'm working on it.

don't install in TK Rom !

Wifi doesn t work !
After wipe dalvik, wifi work !
Can you boost the incall volume?
This kernel not work with Tegrak Overclock!
BLN would be very desirable

Found this tip you can use via the stock dailer:
"Enter this number *#*#197328640#*#* This will open the service mode menu.
Select option [5] AUDIO Select option [1] (VOICE CALL) Select option [2] HEADSET Select option [1] Volume Select option [1] SRC Speech RX Volume Select option [5] 5_lvl : 87 Press the menu button (left side) Choose Key Input Enter a value between 0 and 100, with 100 the loudest setting. Press ok"
This is for headset but you will also find other volume options here, maybe this can do what you want
Nice Kernel, but why did you use the Deadline I/O Scheduler? CFQ should be better than this one.

Deadline is faster than cfq.... bfq still better but so far no kernel implements it on i9100

If you find this post usefull please press the "Thanks" button
wow i like this. hope BLN will come soon...
but, not working with tegrak overclock......dilemma!
The stock is 2.6.35.7, so a jump to the "final" 2.6.35.13 version is a useful improvement, thanks!
Do we require updated Samsung sources to be able to use newer kernel versions? In particular a 2.6.38 kernel with the Automatic process grouping patch would be very useful, not to mention some of the other improvements in PPP support from .37 which makes VPN much more useful.
Cheers.

Deadline is much better than BFQ for database-based systems like Android. On top of that, Deadline is tweaked for flash usage in this kernel.

ZRAM USAGE:
As stated in changelogs since the 4.2 stable version this driver is activated by default. To see how it's running you can use adb or terminal emulator: type
Code:
free
and you'll see swap paging.
To deactivate at next boot: you need a root explorer (i suggest ES File manager, free on playstore) and create a new file called ".noswap" in system folder, reboot and zram will not longer work. To reactivate delete the file above and reboot again.

The kernel can be installed from recovery CWM or by using Odin.
If you download the zip version of CWM reboot into recovery and select install zip from sd card. Reboot and enjoy!
If you download the Tar archive, reboot your device in download mode. Start Odin as administrator (if you use Winblows 7 or Vista) and select PDA. Choose the tar archive and connect the device. Click on start and wait the magic, then remove the cable when the device restarts. Now you can enjoy ..

I am not responsible for damage caused by flash the kernel or to damage caused by YOUR negligence in performing editing operations of the terminal.
This kernel, although based on the samsung official sources, it is not an official binary and as such will be recognized by bootloader: that means by installing it you have lost your warranty.
We are adults and vaccinated and are conscious of what we do, if you're not or you have any doubt, DO NOT flashate do this nor any other kernel.

That is the history of speedwizz kernel, as well as to help out because reading a changelog is always good thing, in this case serves as a reminder to me ...
I started with a good base kernel (SpeedMod for the hardcore) but virtually stripped of all the features we are used to, even the most simple (eg bootanimation) .
I can guarantee that for a noob like me has been (and will continue to be) a tough battle ....... Huge thanks to all the developers, i am learning so much from you.
Changelog Latest version 4.2 stable build
(from version 4.1 beta2)
- New configuration file: speedwizz_defconfig
totally abandoned def_config derived from SpeedMod, the kernel continues on its path already since several versions before this
- Updated the cross-compiler to Linaro Toolchain 4.7 (08-2012)
The result is a general optimization of the code which results in less consumption of resources and greater stability.
Seeing is believing.
- This build fixes several compilation warnings and for several I mean about thirty
the warning message is a message from the compiler, it is not a fatal error (in fact, the compilation went fine) and if it's about an uninitialized function can sometimes affect the stability of a program (the kernel is a set of programs written mostly in C language) .
Most of the warnings that have at compile time are caused by variables or functions not used.
Obviously, the biggest advantage in NOT have this kind of warnings is that less code "dead" is inside a kernel than fewer resources will use the kernel to perform their tasks and the kernel will be more powerful in terms of fluidity and stability.
In any case i will consider a warning as a bug (generally speaking) even if minor, or even if it is not perceptible by the user.
- Added NSTools
You can use this app to configure all the parameters that are managed by the user, OC, UV, BLN, startup scripts, etc. ..
- Improved support to init.d
Now you will create a special folder init.d if it is not present in the rom (as in the case of the stock rom), if it exists this will not be touched and will be activated only support to run parts.
- Cleaned up some scripts in the initramfs
many things were unnecessary and linked to the use of extweaks (since the initramfs kernel are derived from Siyah kernel), which as you know is not supported by the kernel
- Added support to form Zram and Swaps
Enabled by default but can be disabled by the user through simple instructions.
The use of zram is to use a portion of RAM allocated compressed in a single device, in the specific case of this kernel with a capacity of 300mb and allocated in the ram itself, with a compression ratio of about 50%, for a total of about a gig of ram total between real and tablet.
The main advantage consists in maintaining applications in cache (non-active) for a period longer than normal, with a consequent advantage in the experience multitasking.

Changelog Latest version 4.1 beta2
(from version 4.0)
- Improved support for the following categories of Rom (this list includes only those in which the kernel has been tested for a long time, I suggest you proceed with caution, however, since it is a beta version)
1. ICS 4.0.4 Samsung
2. ICS 4.0.4 AOSP (CyanogenMod 9 - AOKP)
3. ICS 4.0.4 MIUI
4. JellyBean 4.1.1
All credits for this to Gokhanmoral, without his initramfs this was not possible!
- Fixed the autorotation bug on AOSP roms
- Modified (and fixed) the install script that caused trouble (severe) at boot: the ROM AOSP did not install the root of it (fortunately do not need it), it cwm manager.apk and even libraries for the BLN
- Fixed the driver cypress-touchkey.c for the proper functioning key illumination touch with AOSP rom and its function BLN.
- Fixed some warnings from the cross compiler

Too good this new kernel.
Performing the test since launch, super stable and battery consumption above average.
I just have a question, what is the best program to control compatible kernel.
I used Voltage control, but would like to use some other better if any??
Thanks Umberto

OMG! I have started to cry reading this post, FINALLY someone brave enough to give this kernel a shot! Well done bro! Enjoy....
Ehm, seriusly, if you want you can use Nstools as well (and better): can control all the parameters that kernel provide plus it is a good alternative to BLN pro (to set the lost call service when enabled BLN)
Try and report, please
Ps.: you are welcome, my friend..

I'll test as soon as possible and already put the result and the final considerations, rsr.
Umberto, I noticed something in your kernel, it is not compatible with the application Away Triangle, because I tried to use the application with the same Kernel and does not work.
Now I do not know if it's the version of the kernel, or the Triangle Away works only with Syah Kernel.
I'm going to this friend, I need to get back to business, I need to have a meeting with my team.
EDIT:
Although not as experienced as the settings and use the Kernel, the app is very good NSTOOL with the kernel.
A friend here in Brazil told me about Rom Toolbox, I will also try and see what happens, lol.

Mmmmhhhh... Strange.
Kernel should support TA. If not this mean that some of the most recent
Changes have breaked some thing.
I will investigate and repair asap.
For now you can use a compatible kernel like siyah, remove the triangle then if you want can flash speedwizz kernel using recovery, without increment counter and triangle.
Good life.

Just as I did, I put Syah, removed the triangle and went back to Speed kernel 4.0, because I'm loving the performance of this new kernel.
I enjoyed seeing you again on your project developed, even if not with the whole of your time, but I was happy.
hugs brother
A new version is available for test, kernel now support multi rom, but DOESN'T BOOT WITH JB 4.1.2 (due to new mali driver).
For details before you use it see the first page or my blog.

Umberto, as passed halloween??
I had some small problems after they installed their latest version of the kernel, but do not know if that has something related.
My kid wont play Monster Life in Mobile, and soon after I installed the latest version of Kernel, I have noticed that the game crashes, having to turn off the phone and reconnects it, it has something to do with the kernel??
If helps, now make cleaning cache and davik too, and still have this problem sometimes
Hugs and great weekend.

If your problem is only with monster life I can tell you it is not kernel related: I've noticed that the crashes are reported as well in market comments.
Just if you are in doubt try with some other kernel and report, I can't try because I don't have a WiFi connection to download and play with it (around 115 mb if I am right).

Okay folks, no fancy graphics or information here. Searching this site will tell you any of the generic information you may be interested in. I am not going to clutter up things any more than I normally do. Which is already enough.
I need to make something very clear here. I'm sure it's just me, but I feel like I need to say it out loud, rather than just leaving it in my source. At least 90% of what I give you is other peoples original work, modified by me to run on whatever device I have. I don't do it to look smart, or be important, I do it 9 times out of 10 because there isn't something already out there. The vast majority of the options I give you are from amazing coders like show-p1948 and faux123. There are random snippets from others too. This time Zarboz contributed a lot in the beginning. I just wanted to make that clear. If you ever wanna know exactly who did something I put into a kernel, go look at the source. If I cannot get the original commit, with them as author, they are listed in the comment. If nobody is there but me, I actually did it.
So, here you go:
Droid DNA Cubed Kernel 3.1.3
Installation:
1. Unzip the file you downloaded.
2. Copy the Modules zip to the SDCard.
3. adb reboot bootloader
4. fastboot flash boot <file> (This will depend on where you unzipped to.)

6. Flash Modules file in recovery.
7. Reboot
8. Profitt!
Please Note: This kernel removes some stock files you will need to use other kernels. Please flash this file before flashing anything else to return everything to stock.

Okay folks, no fancy graphics or information here. Searching this site will tell you any of the generic information you may be interested in. I am not going to clutter up things any more than I normally do. Which is already enough.
So, here you go:
Droid DNA Cubed Kernel 1.0.1
Okay, it's still very basic. I've been watching/talking to Zarboz as he has been making his. I will be catching up a lot of his mods here in the next few days.
Installation:
1. Unzip the file you downloaded.
2. Copy the Modules zip to the SDCard.
3. adb reboot bootloader
4. fastboot flash boot <file> (This will depend on where you unzipped to.)
5. Use menu on phone to go to recovery.
6. Flash Modules file in recovery.
7. Reboot
8. Profitt!
Change Log:
12.01.12: Initial release, 1.0.1
SIO I/O Scheduler
Linaro 4.7 GCC Toolchain
-O3 Build
Force Fast Charge from Chad0989 - This is on by default. I will create a zip to turn it off and post later tonight.

It means that instead of assuming an unrecognized device is USB, it will assume AC, thus charging faster.

just using linaro and -O3 optimization will make this above stock kernel even if the OC hasn't been added yet
Good stuff DSB can't wait to see what you come up with i always loved your rezound work
its been a while since I had to flash in Fastboot... need to clean out the spiderwebs in my ADB closet... flashed great.. thanks allot... any plans on a senseless cubed rom?

Everything seems to be stable and working on the first version for me..
Just one thing and it's not a bug
You know on the YairPatch kernel logo there seems to be a bit of an overlapping of the kernel version at the bottom.
No big deal but would look much better if it could be sorted out.

Why don't you upgrade to 4.1.2? Everything works and the speed is better in my opinion.

i honestly flashed a couple of times using different versions of flashtool. thought something was wrong lol.
on topic: i tried checking yair's site, as well as the op, and i can't seem to find the differences between 02 and 03 kernel. i've already tried both, and 03 seems to be much smoother.

The differences are only in the compile flag optimisations. But yes, 03 is very smooth.

Little bit off-topic, but I remember when the minicm10 came out with the .32 kernel, you was happy with the incredible performance. And after a longer test period you always went back to froyopro or minicm7 due the better performance...
Okay, go back to the thread.
@cascabel: you can't find the differences between the o2 and o3 versions of the kernels because the two kernels source code is same, nothing different. The compiler settings is invisible, this is not add or remove features, the difference is only the increased/decreased performance/stability.
If you interested what is the difference and how to work the code optimization in gcc, use google and you can find lot of information about how to work the o2 and o3 optimization, about the strict-aliasing and tons of other optimization flags.
@afi1982: can you post the gcc flags what you used? Or simple changed to -O3 without additional flags? (now playing with the .32 code to build a gb only kernel).

FAQ
Why is the file size so big?
It includes an uninstaller so also packs the stock boot image and corresponding modules. Plus the Aroma installer adds to the size. Essentially the actual kernel is only ~7.5 MB

How to use gesture wake?
The necessary toggles are located at /sys/android_touch
doubletap2wake > 1 to enable
> 0 to disable
orientation - This will allow you to set in which orientation Sweep2sleep must be enabled
> 0 for both
> 1 for portrait only
> 2 for landscape only
pwrkey_suspend - If set to 1, pressing power button to turn off screen disables s2w/dt2w and pressing the power button to turn on screen re-enables s2w/dt2w
> 0 to disable
> 1 to enable

Are you planning on releasing a version that doesn't use Aroma? I don't see the point in using this Aroma as it just adds an extra burden (and size!) on the user having to work their way through the install process - I simply want to click on the zip and it installs, job done.
Thanks anyway for the kernel as its always good to see new things being developed for the Flo.
Looks great, will defiantly give this a go and report back, thanks!
Edit: Installed with Mahdi ROM and its running beautifully, looking forward to further releases, thanks again.

The AROMA installer is a place holder. Additional configuration will be made available later. Also, it is easier to uninstall the kernel if necessary.

Why only 3.4.10 and not 3.4.9x?
The one thing I've always hated about Aroma is tweaking the settings after, always seems to be overwritten or just not sure what is being set.
Will give it a go.

Kernel 3.4.10 works best in my testing. Upwards introduce changes I am not very comfortable with as they tend to cause some battery drain. At the moment, I do not intend to go further than that.
The aroma will only be a helper of sorts. I will be releasing an app to help configure the kernel soon. Right now, the aroma installer just flashes the kernel. Everything else is default set in the kernel.

duki994 Kernel for Stock TouchWiz LP ROMs
A personal project that had good results and I wanted to share it with others
It's based on official Samsung sources for Lollipop firmware.
Important note:
This kernel should work on any custom ROM that is stock lollipop based
Features:
* Wolfson Audio control (thanks to @AndreiLux)
* Battery charging control (thanks to @AndreiLux)
* CPU voltage control for both A7 and A15 cluster (thanks to @AndreiLux)
* Exposed all OPP voltage controls (thanks to @AndreiLux)
* Powersuspend v1.7 by @faux123 and @Yank555
* LMK, MM and FS powersuspend mods ported from @dorimanx's LG G2 kernel
* SCHED code fixes
* SCHED: HMP thresholds changed and new patches implemented
* Many changes related to ARM instruction code and lowlevel ARM core management
* Enabled NEON mode in kernel with full VFPV4 support
* Added new SHA256 and SHA512 NEON accelerated algortihms - now blazing fast
* UKSM (Ultra Kernel Samepage Merging) - algorithm that's better optimized than standard KSM
* WiFi standby wakelocks (PNO wakelock) reduced
* WiFi userspace power mode/DTIM change (for advanced users ONLY)
* WiFi driver switched from deprecated earlysuspend to use newer powersuspend driver (this is to fix some of bugs that could lead device kernel crash)
* NET updates
* Enabled all TCP congestion protocols and set Westwood as default (best wireless performance)
* Disabled KNOX
* SELinux disabled in kernel
* Fully configurable in Synapse (download from Google Play)
/* Important note to other devs */
You cannot include this to your ROMs. I can't be responsible if anything goes wrong, I can't help with any issues without knowing kernel version and users should be routed to this thread if they want this kernel, or if you recommend it. I think that it's best to separately view custom ROM and custom Kernel, so each dev (ROM or Kernel one) can work on bugs/features and make it as compatible as it can.
However, you can add this thread link and mention me in your thread, so people would know where to ask if some kernel problem arises
Warranty void
By flashing this kernel you will void your warranty. I'm not responsible if you brick your device, or if someone starts nuclear war.
Note:
Don't change voltages on "Busses" tab if you don't know what you are doing. It can reboot your phone if your memory controllers, ISP or MMC controllers can't handle low voltage.
WiFi pasword resetting fix:
Code:
1. open your build.prop file
2. find line ro.securestorage.support
3. change it from true to false (if not already false)
This line being on true will make your WiFi not work good with this kernel. This is due to Samsung's rooting restriction and other Samsung specific workarounds to stop rooting and flashing. Any custom ROM probably has this line changed to false.
Changelogs:

* Added misc tab:
+ ability to take logcat,dmesg,last_kmsg
+ HMP Little packing switch ON/OFF and explanation
* Added optimized ARM RWSEM algorithm
* Fixed HMP so HMP little packing would work good with our implementation
* thermal IPA(Intelligent Power Aware) now updates power tables immediately when voltage changed from Synapse
* entropy depletion fixes
* Enabled FRANDOM random number generator module for more entropy and less lag
* Added NEON instruction accelerated SHA256/SHA224 algorithm. Now we have SHA384/SHA512, SHA256/SHA224 and SHA1 algorithms NEON accelerated - blazing fast
* HMP little packing switch for Synapse
Experimental option made by nvidia. It groups tasks so more of them would be scheduled across power saving cores (A7 cores in our CPU). It may or may not save battery depending on your usage.

Clone ramdisk source in ramdisk_source
Clone kernel in kernel_source folder
Be sure to have project directory structure as written above
After that, you just need to run:
sudo bash build_kernel.sh
in kernel folder. And voila. After finished you have Kernel-slte.zip in RELEASE directory
If it show any errors, open kernel source and type in terminal:
chmod -R 755 *
Then repeat sudo bash build_kernel.sh
awesome job, thank you
finally undervolt .. yay

Is it possible to other variants like Galaxy Alpha SM-G850L Korean? Thanks

I reduce voltage A15,A7 (every speed) by roughly 20mv
gaming (coc,asphalt,etc) for roughly 1 hour; result=stable :good:
edit: volume in the audio also work, louder headphone.
Thanks, I'll try it.
how the battery with this kernel?

Battery? It's better than stock for me. For screen on, this morning I had 50mins SOT and 87% battery left. That's even better than my LG G2, which is a beast according to tests
My father uses Galaxy Alpha, and yesterday he managed to get 4h SOT with HSDPA data on.
When screen off (in suspended mode) it's very low power consumption due to Powersuspend driver. It's better than stock.

I have no access to G850L model. I don't know if it will work.
During this week, if I have enough time, I'll download G850L source and build it with all mods/features and give you to test it
thanks duki994.
which app I need install to control on the kernel?
hi!
1. how do You undervolt by 20mv, in synapse i have steps like 1x,xxMv and can set up -25Mv??
2. I have strange warning message after installed this kernel. it says phone needs to reboot. after reboot the same. just annoying

1. Our voltage regulator accepts 6.25mV step. So you can UV/OV in multiples of 6.25. When you do math, 6.25mV x 4 = 25mV
You can't UV -20mV. You can UV -18.75m (3 x 6.25mV). Next step is -25mV (4 x 6.25mv).

No UV. All stock. Only changed earpiece volume (incall speaker volume) to higher (+4dB if I recall good from this morning). It's for better hearing incall
UV generally doesn't reduce battery consumption (it's maybe 1%-3% less power usage). Real benefit of UV is lower CPU heat and prolonged life of motherboard.
Some chips can't handle UV at all. Some can be UV by as much as -150mV. It all depends on specific chip that came out of fabric process. Note that UV brings instability on some devices.

On which ROM are you? Everything works for me on stock. I have to see if anything changes it.
Did you set secure storage to false in build prop?
I'l automate that in next build.
Kernel doesn't mess with options like recent buttons and Java written parts of Android OS.

Please read OP before asking. Everything is said there.
Synapse is the app with which you can change settings of this kernel.

I am on ozcan rom 4.1. my recent button only works with Nordic based stock which is NEE G850FXXU2COI3 5.0.2 11.09.2015 5614954 and ozcan rom..and with any other rom like rr and cm12.1 my recent button does not work.. secure storage is false by default on build.prop .
