Hello XDA Members,
I am here with a kernel for Otus. This kernel works on Android 7.x based ROMs
Standard disclaimer :
Code:
This product is distributed free of cost and does not come with a warranty. I will not be responsible for anything that may happen to your phone as a result of flashing this kernel. You have been warned !If you come to me saying that this turned my phone into nuclear bomb , I will surely laugh at you !!!
Introduction :
Photon is a fundamental particle of nature which delivers light to us all. It's mindboggling properties like duality, never stopping from being in motion and presence in so many diverse natural phenomena like photoelectric effect, relativity etc. makes the man ultra-curious about it. A photon is born when atoms transition from excited state to ground state. What's the point of this paragraph in a kernel description post?
Well, like a photon this kernel possess duality. How? By giving better battery back up and performance. ( ) What about non-resting nature of photons? Yes, the kernel support will never stop until Nougat says good bye. ( ). OK now don't ask about analogies regarding photoelectric effect and relativity. ( : D ).
Anyways, now coming to the point I am very much glad to present you, the users of otus, my tiny piece of work for our small beast, .
“The Photon Kernel“
I got very much fascinated by the concept of photons when I studied it for the first time and hence (yes, you've guessed it right!) I've named this kernel Photon.
Enough of the physics class today let's look inside the features of the kernel now ( xD ) :
Features :
1)Compiled with UBER toolchain 4.9
2)Used -O3 and graaphite optimisation flag
3)Added few more governers to stock ones. List of all governers :
Impulse
Ondemand
Ondemandplus
Powersave
Performance
Interactive
Userspace
Smartmax
Lionheart
Nightmare
4)More I/O schedulers.List of all I/O schedulers :
noop
deadline
row
cfq
flops
tripndroid
sio
sioplus
vr
zen
bfq
5)Enable Arch Power
6)Disable Gentle Fair Sleepers
So that’s all for the features as of now. More features will be added in future.
This kernel serves me good for daily use and allowes me to use those governers flawlessly.

Great kernel, using it from past 2 days and not facing any issues.
@Hamza Badar, is it possible to add DT2W. It'll be a great feature if added.
Thank you for the amazing kernel!!

yeah and also, if minimum frequency of CPU is less for 98MHz that also a good.. i saw this minimum frequency on inazuma kernel of MM..

which governor can i use for battery??
I have galaxy grand duos phone how can Iinstall sailfish os
Which is android jelly been 4.2.2
Is this still mantained? I would love some more CPU governors, like InteractiveX, Yankactive, PegasusQ, Alucard, Smartmax_eps, etc. Also maybe decreasing the lowest CPU frequency to 50 or 100mhz? Also, sound customization would be great too.

hi.. i need some advice/guide regarding this matter..
first of all, i'm planning on compiling custom kernel myself for my ace. i've succesfully compiled a kernel on my debian box using kernel sourcecode from samsung and also applied bfs patch. but now i dont want to just stop here.
the problem is i dont know where to look for those undervolt patch, smartass governor patch, interactive governor patch etc etc. gooling for "android kenel patch/module" just bring me to precompiled kernel thread, not the source patch itself. so maybe anyone can guide me the right direction? thx before

better to see the github site, lot of kernel source with many patching in there. and i think, for the much customized of samsung kernel, you can just patching, manual diffing will more better because samsung kernel is not vanillaish android kernel. much modification in there.
Sent from my ViewPad7 using XDA App
Custom kernel for the Ace on it's way..?
** Note: This kernel is end-of-life and will no more be maintained. There will be no LineageOS 15.1 or newer kernel be available anymore **
Hi all,
some of you know me from the Samsung devices area, where I provide my kernels already for more than two years to Galaxy S3 and Note 10.1 users for all sort of platforms (Samsung, Cyanogenmod, Omnirom etc.).
Maybe you also know me from my OnePlus One kernels I added in winter last year to my portfolio.
Finally I got a Samsung Galaxy S5 afew weeks ago and decided to port my kernel also to this device. This is a sponsored device, so I want to say a big thank you to the people that made it possible, namely the ones in the German Smartphone Forum www.hubo.in !!!
Please note:
I am not heading to have as many features as possible implemented, this is not my design goal. If you are more into that, move on to other, good existing kernels. If you are searching for a good mix of improvements and new functions while not sacrificing stability, you are welcome here (see below the history section for more info).
For the Samsung Stock Boeffla-Kernel, please go HERE.
Important notes
When using new anykernel concept Boeffla-Kernel: Flash stock kernel of rom first !
Compatibility
Important: This kernel is only meant to be compatible with official LineageOS/Cyanogenmod and nothing else.
So when the kernel does not run on custom rom XYZ, do not even bother me with it or ask hundred times in the thread for compatibility.
I could not care less about it !!
Support
First read the FAQ section on the Homepage !!!
Click here to learn about all possible kernel settings in the config app.
Click here to learn about using the config app.
I will refuse to give support if you do any undervolting and experience freezes or hot reboots.
I will also not provide any support if you do not use Boeffla-Config app to tweak the kernel, other 3rd party tweaking apps are known (and intended) to cause issues.
I will refuse to give support if you have xposed framework installed and reporting any kind of weird issues. My opinion to xposed it quite clear: too powerful for >90% of the users that just mess up their system with it.

Always based on latest Galaxy S5 sm-g900f kernel sources by CM
Kernel runs with SELinux enforcing by default, just as CM12 stock kernel for S5 - but can be configured to work in permissive mode in Boeffla-Config settings
Note: I do NOT upstream the kernel to higher Linux kernel versions anymore as this usually has zero benefit but likely introduces new issues + is a waste of effort in the end

History and design targets
Basically I created my first Boeffla-Kernel in 2012 as there was no kernel for the Samsung Galaxy S3 around that had exactly the mix of functionalities that I wanted. I wanted to have full flexibility in undervolting and charge rates for instance, but did not like the sharpness and/or brightness tweaks many kernels have implemented as per default.
Hence, I began to create my own kernel after a while, adding all the features I like. This is the result of my work, which in the end I decided to share with you. I hope you like it as much as I do.
The objective of this kernel is to have a kernel for daily use. It does not aim for best battery life, or best smoothness or best benchmark scores. Also it does not aim to have the broadest feature set available everywhere.
It aims more for a good mix of all, not sacrificing stability and functionality in the end.
And - most important: It aims to stay quite close to stock !!!
These design targets are also valid for the Galaxy S5 kernel here!!!
This said, I will definitely NEVER implement:
things I do personally not need
things I do not like
things that are in any way dangerous
anything which is highly experimental
f2fs - it is known to cause various issues and compatibility problems
a CAF based kernel
anything that requires upstreaming of kernel parts to a higher kernel major version
So do not even ask for it if it falls into the listed categories. Everything else I am happy to check and decide.
And: I do not really care about benchmark numbers, they say almost nothing as long as something is not completely wrong. Important for me is the feel-good factor.
I am also not interested in gaming at all, so never expect a gamer kernel. It will just not happen...
Compatibility
To reiterate it again: Flash the correct kernel depending on whether you are on Samsung Stock, CM12 or CM11 !!!
Configuration of the kernel
To tweak and configure the kernel, manually load and install the app "Boeffla-Config V2" from the downloads section on www.boeffla.de.
You need at least version 2.1.72 or higher for the Galaxy S5 Boeffla Kernels.
Donation
If you like my work, feel free to donate: Donation-Link
If you donate at least 2,49 EUR (to be in line with the donation app prices on Google Play store), you will receive a personal donation code which unlocks some nice little comfort functions in Boeffla-Config V2 on top.
Source code
All sources can be found in my Github repository: http://github.com/andip71
Credits to developers
Of course, I had never been able to create all that by my own. So I want to give credits to the really good developers around, that have given me all the inspiration and from which I cherry picked lots of the implemented functionalities:
* ZaneZam
* Yank555
* ktoonsez
* Hardcore
* Chainfire
* AndreiLux
* Netarchy
* Gokhanmoral
* Entropy512
* Faux
* Ak
... I just hope I did not forget someone. If so, please let me know and I will add you of course.
Thanks to all of you for your great work !!!
Disclaimer
*** As always - Flash on our own risk! ***
Make sure you flash the correct version depending on your firmware version!
I can and will not take any responsibility for bricked phones or lost data.
It is generally recommended to run a complete Nandroid backup in your custom recovery and safely store your personal data before you flash a new kernel.
Cheers and enjoy

*** You want my support? Then stick to my rules ***
Guys, I am receiving more and more completely useless support requests in different threads. Useless because people provide nothing to be able to help, not even the minimal possible information they could give.
Hence, I will now remind anyone again on the support guide lines stated here:
http://boeffla.de/index.php/support/support
Also you need to ensure you follow the installation guide lines incl. trouble-shooting stated here:
http://boeffla.de/index.php/support/installation-how-to
And to cut a long story short: If you do not at least provide what I request in the support guide lines, I will IGNORE YOUR REQUESTS IN FUTURE.
Straight and simple. I have enough of people wasting my time just because they are too lazy to write details.
Period.
Also as a reminder:
you use xposed? -> no support, everything is your own issue
you use a custom rom and not the official stock or CM one? -> good luck, you are on your own
you undervolt or overclock? -> have fun, but without my support
Sorry, this might sound harsh (and it is meant to sound harsh), but you cannot imagine about how crappy support requests can be. Stating something does not work is just not enough.
Please consider that!!!

Cannot comment for Temasek, as written.. it is for official CM12. And it is only tested by me with official CM12.
If it runs with Temasek - fine. If not, you need to search why it reboots for you. Then Temasek seems not 100% compatible.

@Lord Boeffla
Hi Andi, a big neverending thanks for providing us with an S5 (G900F/klte) kernel.
Coming from my i9300 which ran the whole time with your wellknown and imho best kernel for the i9300 I am familiar with your fine app and highly appreciate your new work for the S5.
And btw: Due to so far not working TRDS for LP/cm12 I still run kitkat for s5 (same with my i9300) using FusionRom which is mostly based on cm11.
Now with Boeffla-cm11 for G900F based on FusionRom 4.4.4 I feel happy again - fast-stable-easy to handle 1A+++

Quick question: Are you coming from another custom kernel?
It might be, some cleanup work is required first.
Just had a user that came from KT kernel and he had to deinstall the two KT apps manually, wipe dalvik and cache. Then it started working.

You must delete in root/system/app/com.ktoonsez.KTmonitor.apk and com.ktoonsez.KTweaker.apk.
Additionally, in Int SDcard the KTKernel Folder with profiles and scripts.
First, install the Boeffla Config, then go into recovery and flash the kernel. Wipe cash and Dalvik and reboot.
For Viper4android user, first deactivate Viper4Android or use the Beoffla Kernel without Boeffla sound settings.
Sorry for my bad English, with this kernel for lollipop tw viper4android work or not? Now i have flashed this kernel and boeffla apk

Hi, I've tested the kernel on Temasek and on a few different Rome.
Bliss Pop Rome, Fusion, Darko ... CM12 unofficial
It's like Horsti G says everything must be deleted from the kernel KT otherwise there are problems. but I have only the KT monitor at run without problems
Especially on the Temasek Rome had 2 people tested the kernel for quite some time without any problems.
Unfortunately the support for other roms is not possible because there are always errors and differences with other roms.
a Idde would make a thread for all other roms. since one could then afford support?
@ cranio84
For Viper4android user, first deactivate Viper4Android or use the Beoffla Kernel without Boeffla sound settings.
sorry for the translation with the googel translator
kind regards
Jakkomo 77
Ok i deactive boeffla sound setting, but where is a guide to install viper4android, because I have tried with more kernel on tw rom and don't work
For sure there are specialised threads for viper4android.
But wrong in this thread to discuss that...
Andi
Ok, i discute un this 3d because your kernel is correlate for me
After maybe a month of working in the kernel.
I guess it's about time to release the kernel for testing.
Downloads in the second post are only there for easy follow ups.
Please read all the sections below before trying out this kernel first.
This kernel comes with absolutely no warranties whatsoever, period.

camctl : script to enable/disable camera for RAM
How this thread is organized.
The OP has been broken down into sections. The first 20 posts reserved for info/wiki sort of.
So when things get updated/added it'll all be in the first few pages for everyone to see.
Each section will be short and to the point so you're having problem with one section.
And you're the type who just has to quote posts you might do so without getting on other people nerves.
And normally I just just ignore the forum's usual craptalks, but at this early stage of development, try to keep the noise minimal
Let's make some things clear first.
This kernel is not for you if you want a stable kernel.
CM11 should already include the stable version of this kernel, so you should just stick to that.
This kernel is only for CM11. No other roms will be supported or even considered.
This kernel is higly experimental. Freshly made, straight from the lab.
So expect some breakage of functionality, random reboots, bootloops and explosions (unlikely, but I gotta cover myself).
Flashing
The zip makes no backup of your current kernel as of now.
So if you wanna go back to shipped CM11 kernel you have two options.
i) Manually move the original modules to system and restore just the boot image from TWRP.
ii) Restore/flash the entire ROM.
As for flashing the zip, you should burn it on a CD, and choose boot from CD in your PC by keep pressing F10/F12 at BIOS screen.
Well no but, you should at least be familiar with flashing and backups.
Breakages
Camera:
Well, it's due to updated ION drivers, which are not compatible.
In the meant time I have disabled memory allocation for camera.
Which should give some extra free memory.
If there's any other stuff broken here but not while using CM11 kernel.
Post it here instead of there. But not the stuff broken in shipped CM11 too.
What are not bugs.
24mb of less RAM:
Linux ate the RAM, no really.. linux eats RAM http://www.linuxatemyram.com
Well it's due to enabling memory cgroups.
Android says keep it enabled for low ram devices.
As per https://source.android.com/devices/tech/config/low-ram.html
Also, see the below sections for frequency scaling
Bug reporting
You know you won't get help the next time from a kernel dev if you give them a logcat.
So get the dmesg or no help for you.
And /proc/last_kmsg is not working due to ram console issues.
So if you're gonna be reporting random reboot issues, make it reproduceable.
And make it precise. If the issue is caused because you have installed, some 10 or 20 other mods.
Good luck solving it.
What are in the kernel.
You get your usual stack of IO schedulers, governors, dynamics and mods. They won't be included in the change log below.
I don't even know what half of those are.
So don't ask me what/which one to use. See them for yourself.
You also get some usual tweaks, which can be changed with any kernel control app you like.
Same don't ask what/how to tweak.
If you want something to be added that you don't find. Let me know, and I'll see what I can do.
Frequency scaling
Frequency scaling is already included from r3 onwards. So the previous instructions no longer applies.
The default min and max frequency is 1Ghz and default governor performance. ie. same as stock.
Any change to that is your own choice.
And your own loss if something goes wrong.
There are some limits to it.
i) It can be only changed 10 times a second, so it might cause lag sometimes.
So choose your governor and scaling wisely. Battery or performance. You decide.
Underclocking has been removed.
Going below 1000Mhz makes no sense, as the core voltage is the same.
There is no point in reducing frequency, if the power consumption is constant.
Overclocking has it's own section. See below
Overclocking
First if you were using the older broken cpufreq driver and were in the impression that you were at 1.6Ghz you're gonna damage your device.
The driver written by me, really overclocks the cpu and the whole system, yeah mines fractured too. Nothing I can do about it.
So use at your own risk. And don't discuss about the safe overclocking frequency. There isn't any.
Issues caused by overclocking are not issues. or bugs.
I won't give you any overclocking advice. But here's one anyway.
Overclock only when necessary and do not keep the values persistent at boot, "Set at boot" in apps.
Changes from stock:
A lot of thing has been updated, changed, modified. I will have to go through source again.
A short list of changes I can think right now will be posted soon.
- The you know, built with some GCC-5 Linaro toolchain and O2.
- Cherry picked upgrades from various kernel sources.
- Disabled a whole lot of Samsung debugging.
But there's more... see the Github repo.

Lord Boeffla is the Gun of OnePlus phones. Many people know him from OnePlus One and yes me too. He is popular because of his powerful Boeffla Kernel which gives a lot of added tweaks in Kernel Management with Stunning battery life. Also, we can see a significant improvement in Benchmark if we integrate Boeffla Kernel with our Android system. When I purchased OnePlus 2, it was Oxygen OS 2.1.2 out of the Box which was quite buggy with horrible battery life. So, I decided to change the Kernel and Boeffla Kernel was my only trusted option.
He released his Kernel for CM 13 Grarak Build. Read below to see some of the Notice from Lord Boeffla and easy installation Instruction for this Kernel.
Temporary ALPHA notice From Lord Boeffla :
This is currently an ALPHA kernel, this means Lord Boeffla do not officially support it.
Use on own risk. If you report issues, they might get fixed, or not.
As long as CM for the OP2 is not official, Lord Boeffla will not put lot's of time into looking issues.
The kernel is only tested against Grarak's unofficial CM13 builds you can find here (if you do not use this, expect everything):
Mod edit: links removed.
Hope These Guide help you Don't Forget to Hit Thanks Button if you like this !
Dont wanna be rude but knowing how to flash a kernel zip is common sense.
And wrong section it should be under general (tbh why would anyone need this).
