Please upload the source code!
This is not for bullying you, but kernel is released under GPL license which means you can modify it but HAVE TO provide the source code, otherwise it would be illegal and a copyright infringement.
And that wouldn't be nice in xda

I'm guessing that this is based on Slim kernel (the only kernel now that is on 3.0.80 is Slim...and his emphasis on Slim ROM) with his modifications done in Nexus...but free of OC and UV...and as I already stated before, codeworkx already modified vibration so that it can be adjusted, plus it is based on Gnex...so what makes this exclusive? It can be tweaked with Trickster MOD even before you "added" this feature...but one thing that interest me is the new RIL...so far it is only applied on the omap4 common device tree: https://github.com/Ryuinferno/andro...mmit/0641411c681ca67a26b212538955e9e08206216d ...but not the t1 kernel source...so all AOSP ROMs should have it regardless of kernel...

source is the same for nexus (cyanogen source ) i update to 3.0.80 with cherry--pick by fancykernel github....

It is still not sufficient...even your Nexus kernel repo is not updated...you must at least point out what is the difference or cherry picks...keeping a Linux kernel as proprietary software is illegal...

[Kernel][AOSP][4.3/4.4][Linux 3.0.101][TWRP 2.6.3]aidfarh's kernel (updated 13-12-20)

WARNING!!
This kernel allows you to set the CPU frequency beyond the stock rated frequencies. Do this at your own risk! I will not be responsible for any damage to your device if you do so!
INTRODUCTION
It seems there's a dearth of kernels for JB 4.3 AOSP-based ROM for the i9100g. So I'm deciding to share my own custom kernel for those who want some alternative to the the built-in kernels on the AOSP/CM10.2-based ROMS.
I can't think of a fancy name for this, so let's just call it aidfarh's kernel for now.
Any feedback is welcome.
FEATURES
Based on Mokee v43 kernel, which is based on CM10.2 kernel
Updated to Linux version 3.0.98
TWRP 2.6.3 recovery
USB fastcharge available (disabled by default)
Governors:
Ondemand
Hotplug
Userspace
Interactive V2 by imoseyon
InteractiveX by imoseyon
Performance
Powersave
Conservative
Lulzactive
PegasusQ
AbyssPlug
I/O schedulers:
cfq
noop
deadline
row
Dynamic management of dirty page writebacks
Some optimisations - hard float, some cache optimisations, disabled tracing
CHANGELOG
20131010:
Added 200 & 1350 MHz CPU frequencies. Overclock/underclock at your own risk!
Updated row scheduler to V4 and tweaked default settings.
Modified power.t1.so and included in kernel zip.
20131013:
Prevent omap4 duty cycle from overriding user selected cpu max_frequency.
Optimize cpufreq transition latency.
20131023:
Update to make it work with new multi-sim feature in CM-10.2.
20131113:
Updated to Linux kernel version 3.0.101.
Added SIO scheduler.
20131220:
Android 4.4 (built on Omnirom 4.4 source tree).
20131222:
Released different versions for Omnirom 4.4 and CM11.
Omnirom 4.4 version - fix max frequency behaviour (power.t1.so)
REQUIREMENTS
Android 4.3
This kernel should work with any CM10.2 based ROM. Tested on CM10.2 and Mokee
It would probably also work with non-CM AOSP 4.3 based ROM, but due to differences in implementation, some features might not work 100%.
Android 4.4
I've produced two versions of this kernel. One is compatible with Omnirom 4.4 and the other is compatible with CM11. Compatibility with other Android 4.4 roms is unknown.
INSTRUCTIONS
Flash the zip in CWM or TWRP recovery.

P.S. For some reason I can't edit the first post. Is there a problem with the server? (Edit: solved by using Firefox instead of Chrome)

Showing some support here......are you editing using Tapatalk? I face that from time to time...
You forgot this: https://github.com/aidfarh/android_kernel_samsung_t1/commit/6faac1345139ea7301dd4c98d7bf200b77167a9a
And just a heads up, the last time when I tired to apply interactiveX, I faced random reboots in recovery...

I was using Chrome. After clicking the Edit/Delete button I just got that cursor spinning on and on. Editing using Firefox was fine.
And yeah, I also had the same problem with interactiveX, but that was back during ICS days. The reason was interactiveX didn't coexist well with interactive, so my solution back then was to use only interactiveX and disable interactive. I'll do some more tests and hopefully the newer versions work well.

it should work because the kernel is multirom patched but only the twrp recovery is missing

if only CM have working GPS... daamn

Using this kernel the app animations lag a lot, also it seems like even though I'm forcing the min and max CPU clock to 1836mhz, It's still maxing out at the default 1.5ghz. Using the latest CM11 nightly on the pollux with a clean install. Any suggestions?

ok guys version 1 reuploaded the problem was the voltages which i did not change for the tabs and please use simple gpu governor because ondemand drains more battery.

It is compatible but trickster mod app is still better

Seems to be one of the best kernel
As title say, it's true. I installed this kernel o cm11.pollux10072014 and everything is just great. I was made my root with a help by xzdualrecovery. Put some mods as a beats 2.0 and voilà... Everything is a perfect. CPU is ticking on 1728 MHz with a governor INTERACTIVE and GPU is on 627 MHz and the governor is PERFORMANCE. I'm using 3c toolbox pro, formerly called Android Tuner to set all clocks, governors and build.prop and the stuff include OOM, SD Card boost, Entropy etc. etc. So now, I have in a new Antutu benchmark (5.1) score about 25500 points. So big thanks to the developer for this great kernel. Have a great time, Peter :good: :laugh:

Hi! Great kernel, but seems to be missing the "call touches while screen off problem" which is already fixed in faheem's kernel: https://github.com/faheemkamal/android_kernel_xiaomi_dior .

v1.7 released!

Just for CM/AOSP Roms?

Will this work on mokee 6.0?

Any plan to port from the current kernel source from 3.4 to lets say 3.10.x?

Hi! I'm on cm12.1, can I install this kernel? What are the instructions to install it? Will I lose my data? I have xposed installed.

pls update the camera drivers
in blisspop rom the camera goes fully black and then comes back multiple times when coming from sunlight to my home..
also will it work in 6.0 based roms ???

network problem
network reset while cellular data on.luckly i have install kernel auditor before flash this.change misc setting westwood to highspeed.n its seem okay for now.need to investigate more.i search kernel that can boost my gaming performance,but i too scared to try kernel auditor tweek.can u suggest to me.anyway thanks for this kernel.

@sakindia123 any plans to update the kernel..?

I tried on cm 11 ..its stable(some kind of spanish development) cpu Hotplugs were disabled by default .. .. But there was same lagg as it was before this kernel... And yes wifi stopped working too ...so yeah !!

Main error i found after installing this was my screen and home+back+menu buttons didnt work at all..

I'll try to see if it solves the touchscreen error, thanks!

[KERNEL][Z][6.0.1][CM/AOSP] Airless Kernel

Introduction
The idea for creating this kernel came up around a year ago, during early LP custom ROM builds. I thought it would be a nice idea to fork the most advanced kernel at the time, EvoMix, developed by our renowned Olivier, Joe (SuperHanns) and Alex, and add to it the latest upstream 3.4 patches as well as mix its features with another good kernel, KMA.
After that experiment turned out not so bad, me and fellow xda user BrateloSlava got an idea to continue developing that mixed kernel with our own cherry-picks from the best kernels available for various devices, and use it in my builds of RR and later GZR Tesla ROM.
Now, one year later, I continued the development that BrateloSlava did on the kernel for the last months for my Tesla and Validus ROMs, and I thought it would be a nice idea to extend this kernel's availability to the users of all custom ROMs around at the moment.
So, here is Airless Kernel for Xperia Z, compatible with all CM/AOSP based Marshmallow ROMs.
Features:
CPU
- Governors: ondemand, interactive, performance, intellimm, yankactive, yankdemand, zzmoove, barry_allen
- Multicore Power Saving - tries to group tasks into the least cores possible
- Schedule workqueues on awake CPUs
- CPU Frequency underclock (192 MHz) and overclock (1.7 GHz) capability
- Voltage regulation
Thermal management
- Simplified and efficient thermal driver
- Flexible ramp threshold temperature
GPU
- Governors: simple, ondemand, performance
- 27 MHz idle frequency for ideal power saving
- Overclocked to 487 MHz
Sound
- Faux Sound Control allowing amplified speaker, headphones and microphones volume
Misc
- RGB subtractive color control
- I/O Schedulers: sioplus, bfq, fiops, zen, row, deadline, noop
- Dynamic FSYNC
- Kernel Samepage Merging
- ARM Auto Hotplug (mpdecision replacement) - no tunables
- Gentle Fair Sleepers
- PM: Power Suspend as a replacement to Early Suspend
- TCP congestion protocols: westwood, highspeed, cubic, reno
- Disabling of some well known wakelocks (e.g. msm_hsic_host)
- Double Tap to Wake
- Fast Charge
- Vibration Strength control
- Compiled with latest UBER 5.x GCC toolchain
- Latest upstream patches: 3.4.112
- Many build flag optimizations (graphite, Ofast)
Download
Latest version (20160901)
Installation:
- Make sure you're running a CM or AOSP-based Marshmallow ROM (Resurrection Remix, AOKP, etc..)
- Flash the zip in TWRP 3.0 (tested, recommended) or other compatible recovery
- Reboot

Tunables for reducing minimal brightness:
Code:
### Reduce backlight brightness
## to revert to default - enter 0
echo "8" > /sys/module/leds_lm3533_ng/parameters/lm3533_bl_reduction;
## values of brightness, lower than lm3533_bl_brightness_min, are being decreased by lm3533_bl_reduction
echo "30" > /sys/module/leds_lm3533_ng/parameters/lm3533_bl_brightness_min;

Important: disable mpdecision in Kernel Adiutor. This kernel has its own hotplugging driver.

Oh god thanks, i can't wait to try this kernel :fingers-crossed:

How do I make make use/activate it?
Also, could you please add pre-tuned Gamma settings like Tommy-Geenexus did for his Zombie Kernel? As you are well aware, the XZ screen by default is very dull and could do with extra constract/saturation.
Thanks
Edit--
After flashing this kernel, it feels a bit sluggish as if it's saving too much power.

Will install it now. Can you add lower brightness like in zombie kernel?

There is already lower brightness, you'll just need to set up a init.d script with these lines:
Code:
### Reduce backlight brightness
## to revert to default - enter 0
echo "8" > /sys/module/leds_lm3533_ng/parameters/lm3533_bl_reduction;
## values of brightness, lower than lm3533_bl_brightness_min, are being decreased by lm3533_bl_reduction

I may add pre-tuned gamma for next builds, until then use the RGB control in Kernel Adiutor -> Screen.
If you feel it's slow, just tune some parameters in kernel adiutor, like up_threshold in the cpu governor, disable multicore power saving etc. Also check if there's a stuck throttled cpu max frequency, that can happen sometimes if it throttles during boot.
Anyway for me it's not sluggish at all, I wouldn't have published it if it was.
Also I'd like to kindly remind all to use the devdb feature and at least provide logs for any problems you encounter and state the ROM you use and its version.
Devs are not psychic to know what's going on with your usage.

Sorry, I'm not planning to make blind builds.
If there's any dev that owns odin and is willing to do it, he can freely rebuild my kernel for it, just keep the source references and filename.

Nice to see a Custom Kernel for our old phone . Thank you for your hard work, it really made a difference in speed on my phone running the latest version of RR.
As a request, can you add to the GPU the 400Mhz option? I mean I'm not fond of overclocking, and prefer to use the stock speed regarding the CPU and the GPU.

Unfortunately an additional frequency cannot be added due to known problems with frequency decisions of the driver when it's added, so it would have to be fully non-overclocked if we want to have 400 MHz.
I can assure you that there's no significant battery drain with 487 MHz nor any other issue, but if you totally insist on having stock max frequency, I can provide an optional version of the kernel with GPU OC disabled.

No need to do this. I will just downclock to 320Mhz, since the difference in performance isn't that big to affect my daily use. Anyway you are awesome for making this offer.:good: You don't see this kind of thing everyday.
