Since the moment that most of x10 users are using custom kernels and our devs are working hard to add new features and add-ons, i think that this thread can be a good place for most of us,like me, that would like to know much more about technical specs and options and for all devs, like a place for reporting experiences and give suggestions.
Before starting..
ALL CREDITS AND MANY THANKS TO:
- zdzihu for providing us custom kernels and for all his hard work in x10 development
- DooMLoRD for modding and adding new features and helping us with kindly support
Link to Z’s kernels: http://forum.xda-developers.com/showthread.php?t=1135475
Link to DooMLoRD’s kernels: http://forum.xda-developers.com/showthread.php?t=1172200
In the last few days, DooMLoRD has worked over his kernel ( v03) in order to add new I/O scheduler types and new CPU governors and he has let us the possibility to choose all settings we want and prefer (according with his kernel’s name “Power to the people”). So now, the objectives of this thread are:
-Post and link information about scheduler and cpu governor types
-Post tests, opinions, comparisons and suggestions about differences between them and over different ROMs
So standard posting form should be as below:
Kernel type ….(including max OC frequency used)
ROM and baseband version …
…all that you want regarding cpu governors and schedulers… ( benchmark tests are very appreciated )
Here, there are some starting and basic information:
http://en.wikipedia.org/wiki/I/O_scheduling
http://www.mjmwired.net/kernel/Documentation/cpu-freq/governors.txt
I hope this thread can be useful for all and may become a way of improving our experiences with the x10!!
Best regards

my phone wroks fine @ 1152 with doom's kernel v3 x series (UNDERVOLTED)
@1152 interactive governer is the fastest and doesn't drain the battery. smartass though i think it's less battery consuming but is laggy.performance governer: wlod after a pretty time
@1190 smartass:so laggy and can't use it. interactive &performance :reboot
what's strange for me here is that with WB cust. kernerl 4.0.3 phone reboots always @1113 and didn't be stable till i reduced the MAX frequency to 1036
now with doom's kernel it's stable @1152 is that because of undervoltage?!! and if so..can i reach @1228 with more UV ?!!
for me i didn't use the s series (same kernel with stock voltage) so can't decide
I got error: "failure at line 1: copy_dir package: system system: installation aborted" when flash Doomkernel v4b for lockbootloader. Can u help me to fix it?
Yeah sometimes you get errors but still the kernel gets installed
Go to Settings-> about phone and check the kernel version
How about others added in v6 of doom's kernel
such as: smartassV2,interactiveX and etc..

Dragon546 Thank you for few pointers regarding on setting up this thread . Your thread regarding Siyah kernel is great and hope i can achieve the same by helping others who use this kernel the same you have done for Siyah. Thank you
Nrk_2k Thanks for the FAQ. Your help is gladly appreciated.
To anyone else who would love to contribute who uses the kernel N.E.A.K please feel free to leave any information as possible. Many thanks again and lets hope we can help each other in true XDA community style
Governors
1) Ondemand
2) Lulzactive (default)
3) Performance
4) Lagfree
5) Conservative (module)
6) Lazy (module)
I/O Schedulers
1) BFQv3-R1
2) Noop
3) SIO
4) VR (default)
Governors Guide:
1) Ondemand
Default governor in almost all stock kernels. Simply put, Ondemand jumps to maximum frequency on CPU load and decreases the frequency step by step on CPU idle. No suspend/wake profiles. Even though many of us consider this a reliable governor, it falls short on battery saving and performance on default settings.
2) Lulzactive
This new find from Tegrak is based on interactive & smartass governors and is one of our favorites.
Old Version: When workload is greater than or equal to 60%, the governor scales up cpu to next higher step. When workload is less than 60%, governor scales down cpu to next lower step. When screen is off, frequency is locked to global scaling minimum frequency.
New Version: Three more user configurable parameters: inc_cpu_load, pump_up_step, pump_down_step. Unlike older version, this one gives more control for the user. We can set the threshold at which governor decides to scale up/down. We can also set number of frequency steps to be skipped while polling up and down.
When workload greater than or equal to inc_cpu_load, governor scales CPU pump_up_step steps up. When workload is less than inc_cpu_load, governor scales CPU down pump_down_step steps down.
Example:
Consider
inc_cpu_load=70
pump_up_step=2
pump_down_step=1
If current frequency=200, Every up_sampling_time Us if cpu load >= 70%, cpu is scaled up 2 steps - to 800.
If current frequency =1200, Every down_sampling_time Us if cpu load < 70%, cpu is scaled down 1 step - to 1000.
3) Performance
Sets min frequency as max frequency. Use this while benchmarking!
4) Lagfree
Lagfree is similar to ondemand. Main difference is it's optimization to become more battery friendly. Frequency is gracefully decreased and increased, unlike ondemand which jumps to 100% too often. Lagfree does not skip any frequency step while scaling up or down. Remember that if there's a requirement for sudden burst of power, lagfree can not satisfy that since it has to raise cpu through each higher frequency step from current. Some users report that video playback using lagfree stutters a little.
5) Conservative
A slower ondemand which scales up slowly to save battery. Simply put, this governor increases the frequency step by step on CPU load and jumps to lowest frequency on CPU idle.
6) Lazy
This governor from Ezekeel is basically an ondemand with an additional parameter min_time_state to specify the minimum time cpu stays on a frequency before scaling up/down. The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand. Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state on a step. Lazy also has a screenoff_maxfreq parameter which can be configured to specify screen-off max frequency.
I/O Schedulers Guide:
Q. "What purposes does an i/o scheduler serve?"
A.
Minimize hard disk seek latency.
Prioritize I/O requests from processes.
Allocate disk bandwidth for running processes.
Guarantee that certain requests will be served before a deadline.
So in the simplest of simplest form: Kernel controls the disk access using I/O Scheduler.
Q. "What goals every I/O scheduler tries to balance?"
A.
Fairness (let every process have its share of the access to disk)
Performance (try to serve requests close to current disk head position first, because seeking there is fastest)
Real-time (guarantee that a request is serviced in a given time)
Q. "Description, advantages, disadvantages of each I/O Scheduler?"
A.
1) Noop
Inserts all the incoming I/O requests to a First In First Out queue and implements request merging. Best used with storage devices that does not depend on mechanical movement to access data (yes, like our flash drives). Advantage here is that flash drives does not require reordering of multiple I/O requests unlike in normal hard drives.
Advantages:
Serves I/O requests with least number of cpu cycles. (Battery friendly?)
Best for flash drives since there is no seeking penalty.
Good throughput on db systems.
Disadvantages:
Reduction in number of cpu cycles used is proportional to drop in performance.
2) BFQ
Instead of time slices allocation by CFQ, BFQ assigns budgets. Disk is granted to an active process until it's budget (number of sectors) expires. BFQ assigns high budgets to non-read tasks. Budget assigned to a process varies over time as a function of it's behavior.
Advantages:
Believed to be very good for usb data transfer rate.
Believed to be the best scheduler for HD video recording and video streaming (because of less jitter as compared to CFQ and others)
Considered an accurate i/o scheduler.
Achieves about 30% more throughput than CFQ on most workloads.
Disadvantages:
Not the best scheduler for benchmarking.
Higher budget assigned to a process can affect interactivity and increased latency.
3) SIO
Simple I/O scheduler aims to keep minimum overhead to achieve low latency to serve I/O requests. No priority quesues concepts, but only basic merging. Sio is a mix between noop & deadline. No reordering or sorting of requests.
Advantages:
Simple, so reliable.
Minimized starvation of requests.
Disadvantages:
Slow random-read speeds on flash drives, compared to other schedulers.
Sequential-read speeds on flash drives also not so good.
4) VR
Unlike other schedulers, synchronous and asynchronous requests are not treated separately, instead a deadline is imposed for fairness. The next request to be served is based on it's distance from last request.
Advantages:
May be best for benchmarking because at the peak of it's 'form' VR performs best.
Disadvantages:
Performance fluctuation results in below-average performance at times.
Least reliable/most unstable.
Q. "Best I/O Scheduler?"
A.There is nothing called "best" i/o scheduler. Depending on your usage environment and tasks/apps been run, use different schedulers. That's the best i can suggest.
Considering overall performance, battery, reliability and low latency, it is believed that
SIO > Noop > Deadline > VR > BFQ > CFQ, given all schedulers are tweaked and the storage used is a flash device.
Q. "How do i change I/O schedulers?"
Voltage Control or No Frills from market.
Or init.d script:
echo "scheduler-name" > /sys/block/mmcblk0/queue/scheduler
Reserved by me for future use! (if i find any)

Full FAQ - All questions with answers will be compiled here.
Below is a list of all questions that have solutions provided.
Question: What does it mean by no AOSP support?
Answer: AOSP roms are CyanogenMod based roms like CM7, CM9, MIUI.
- Samsung based roms are supported (except for ICS XXKP* based roms) in current versions (ICS, MIUI etc themes are just that, themes, they have no impact on rom or Kernel).
- Samsung based roms will usually say they are based on one of the following:
XXKE*, XXKF*, XXKG*, XXKH*, XXKI*, XXKJ*, XXKK*, XXKL* (* stands for build number)
Question: I'm getting lag when playing games like MW3, GTA III, etc. What can I do?
Answer: Changing to the ondemand/interactive/lagfree governors will provide better performance, but may decrease battery life.
Question: Why can't I see any of my photos in Gallery or my music in Music Player?
Answer: There was an issue with this for some in v1.1 and below, this should be fixed in v1.2
Question: Why can I choose governors in CWM recovery as well as in Voltage Control?
Answer: The options in CWM Recovery are for enabling governor modules only, so you still need to set the governor you want to use in Voltage Control.
Question: Will this Kernel work with the CWM app?
Answer: No, CWM app support is not currently supported
Question: I can't enable Conservative or Lionheart Governors, or the Voodoo modules in CWM, what can I do?
Answer: Make sure that the folder init.d exists under /system/etc/
Question: I have enabled Conservative and Lionheart in CWM, but Voltage Control is not showing Lionheart, why is it not there?
Answer: Because the Lionheart "governor" is just tweaks to the Conservative Governor, when the Lionheart tweaks are enabled you have to select Conservative in Voltage Control. Lionheart == Conservative + Tweaks, this is why it is left named as Conservative in Voltage Control, as adding a separate Lionheart Governor would just make the Kernel bigger for the sake of a name.
Question: Can I change BUS voltages with this Kernel?
Answer: No, You can only change frequencies, voltages are locked.
Question: I've activated the voodoo modules, but they don't appear to be working. Do I need to do something else?
Answer: In order to use the voodoo mods you need to download the corresponding apps from Google market.
Question: I enabled conservation governor and Lionheart, how can I see that both are active and ready to use?
Answer: When you have both modules enabled, N.E.A.K. will add 2files into your system.The first one is located in "/system/etc/init.d/" and is called "S02conservative"; this will enable the module during boot.
The second file is located in "/system/etc/" and is called "lionheart"; the file itself is empty, but the kernel knows that with this file it has to use the tweaks to transform conservative into Lionheart by changing settings.
Question: Why can I only change core speed from 100-1200mhz when the other Kernels give me higher values and better benchmarking scores?
Answer: The S2 is one of the fastest smartphones available, and there is still no application which forces our phone to use its max power. The top 3D games, like Riptide/ShadowGun/MC3/Nova2/GTA3/and other, perform smooth and fast with max 1200mhz.
And benchmarks, come'on guys/girls, do you really need a p-meter to show people how good our s2 is?
Question: On which ROM was Kernel tested?
Answer: It was tested by us, the community, with following Roms
Hyperdroid (deodexed)
CheckRom (deodexed)
Stock KK5 (odexed)
Question: Are custom bootanimations and init.d scripts supported
Answer: Did you read the 1st post? Guess not, then you would already know that both are supported.

Question: I am thinking of flashing this kernel and a new rom. What order should I do this in?
Answer: Most roms these days have a kernel in the package as well. So Flash new ROM, clear cache/dalvik/etc. Then flash this kernel, and again wipe cache/dalvik/etc to make sure phone is clean and clear for best performance. After this you can then flash any other extras you want to add.
Question: I have enabled Conservative and Lionheart tweaks, and set in Voltage Control (NO Frills, SetCPU, etc) but when I restart my phone Voltage Control says its on Lulzactive. What am I doing wrong?
Answer: You need to make sure you save the settings as boot settings after you have chosen your governor/IO settings etc.
I think I got all of the questions, but if you see something that I have missed, please feel free to PM me and I will add it in.
Thanks to _Garry_ for providing some extra Questions/Answers.
Okay, noob alert here!!
I'm a total newbie, who owns a GS II running Lite'ning ROM v6.1.
I have these questions:
1 - N.E.A.K. states it's got Voodoo. Does it mean that this will improve the audio output as it did on the SGS?
2 - Which ROM should I flash so as this kernel is compatible with it? Will CM7 work? Or could you recommend any other ROM? (Eye candy needed, too, like fancy animations!)
3 - Would this theme run totally fine with the combination: http://forum.xda-developers.com/showthread.php?t=1334922 ???
4 - Could someone guide me as to how do I got about installing this kernel with a recommended ROM using ODIN3?
I'm a really confused guy..
Thanks for all the help people!!!

You need to download the application Voodoo Louder from the market firstly to be able to make it work...The kernel already provides the modules so the app could work.
You can flash any rom you like..Even on litening it would work the kernel..My suggestion though either go with Hyperdroid rom which i am using at the moment or Checkrom..
The ICS theme by Master Vert again if you flash any deodex rom that should work. As long as it is not themed up like Litening rom..So my suggestion already gave it to you above....
And a guide on how to install the kernel it is simple...Use CWM easier and quicker...Flash a rom of your choice..Guides are always on the first page of a thread. Then when you flash that rom and you are all set up then flash the kernel through CWM...And that is it..You are done

In order to not steal this topic (that is intended for the NEAK kernel), I suggest you read some of the excellent FAQ / Howto / etc topics here on XDA.
Next to that, almost every ROM has installation instructions.
In short:
Flash a kernel with CWM support like CF Root kernels via Odin.
From then on, you can flash via CWM in the recovery menu or via CWM manager or DarkyOTA app.

To flash a kernel via CWM, first download the cwm version of the kernel, then copy that zip file to your phone (root directory of you internal memory is usually easiest to find) them boot into cwm recovery, choose install a zip from sd, then choose zip file, then select the kernel zip and install.
Hope that helps :-D

Aww, man! I'm extremely sorry for asking so many questions, but I just can't avoid it..
Only one question:
Say, I've installed CheckROM.
Now I wanna install N.E.A.K. using Clockwork Mod
How do I do it? I mean when I boot into CWM recovery, what do I select to install the zip? Do I just select "Install ZIP from SD Card" and select the ZIP and will it be flashed? Or is there some other method for it?
Once again, really, really sorry for all the time I'm frustrating you guys..

Yup, you select "install zip from sd card"
then select "choose zip to install"
and then select yes from the install prompt after choosing the kernel zip. It will install itself from there. All you need to do is select "reboot phone" after it has finished installing. Then you are done

yep download checkrom from here http://www.multiupload.com/19H1I2X0GV copy it to your mass memory or use phone to download it
reboot into cwm , install zip from sd card , find checkrom zip , install it
its a very good rom too
edit
installing checkrom will install a different kernel so :
install checkrom
install kernel of choice
install theme before mods if you use ics theme by vert

I just rated 5 stars.
And now i throw a question for simone:
you have fb fanpage, wtf...WHY????? ^^
Oh btw:
flashing via recovery should have a bit more info else the so called noob will scream why doesnt app XYZ not work ^^
Would recomment to change it to:
TO FLASH ZIP:
- boot into recovery
- wipe cache
- wipe dalvik cache
- install kernel zipfile

*** This kernel is now end-of-life, not supported and developed anymore !!! ***
Hi all,
some of you know me from the other OnePlus or Samsung devices areas, where I provide my kernels already for more than three years to OnePlus One, OnePlus Two, OnePlus X, Galaxy S5, S3 and Note 10.1 users for all sort of platforms (Samsung, Cyanogenmod, Omnirom etc.)
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).
Compatibility
Important: This kernel is only meant to be compatible with official OnePlus OOS 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 !!
To add: An open beta (aka community build) is NOT an official build supported here. If you use a community build and have issues, don't complain or even report. I am not merging any kernel changes from open betas into my kernels !!
Important notes
When using new anykernel concept Boeffla-Kernel: Flash stock kernel of rom first !
This kernel is ONLY compatible to OxygenOs stock, nothing else !!!
If you are using a custom rom that bases on OxygenOs, it might work. However, if it does not work, do not expect me to do tweak to make the kernel running with your favorite rom. I would not do it - my one and only reference is OxygenOs stock.
It is not supposed to be compatible to CM, HydrogenOS etc.
Also note: You have to use Boeffla-Config app which I provide on my homepage to tweak the kernel. 3rd party apps will not be able to unleash the full power of the kernel.
Installation
Read the install instructions in the support section on the Boeffla Site.
Support
First read the FAQ section on the Homepage !!!
Click here to learn about all possible kernel settings in the config app (outdated at the moment).
Click here to learn about using the config app (outdated at the moment).
I will refuse to give support if you do any undervolting/overclocking 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.
Otherwise, you can get in touch with me via the support e-mail address: [email protected]
Please provide kernel version, rom version, a detailed issue description and ideally supporting screenshots or log files.

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 OnePlus 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 kernel only if you are running a compatible rom !!!
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 2.4.02 or higher for the OnePlus 3 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
* Grarak
* Yank555
* Hardcore
* Chainfire
* AndreiLux
* Netarchy
* Gokhanmoral
* Simone201
* Mialwe
* Entropy512
* Faux
* Harunjo
* FranciscoFranco
* Ak
* Osm0sis
... 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.

*** 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!!!
Andi
Allright folks, thread is open. Kernel is available for download.
Before you start, please make sure you read the following information at least:
http://boeffla.de/index.php/support/installation-how-to
http://boeffla.de/index.php/support/support
If you have trouble, I ask you to also scan for your issue in the OnePlus 2 thread, as major parts are the same on both devices (http://forum.xda-developers.com/oneplus-2/orig-development/kernel-boeffla-kernel-05-10-2015-t3218164)
Enjoy

Let me create a stock kernel section for it on www.boeffla.de, then yes. But this can take till tomorrow, I am out very soon today.
Apart from that, you can always flash OOS dirty over, this brings you stock kernel back.

Yeees, but... not 100%.
IMHO it backups the kernel image, but not the kernel modules too.
And OnePlus is using kernel modules on OOS.
Just to be very precise.

It finally happened
OMG.
Now I have no excuses anymore to not buy a Oneplus 3.
So it was a short interruption without Boeffla on LG G4 (5 months)
Many, many thanks for this.
Hail to Lord Boeffla. I can not live without your kernels
Greetings and keep calm.
Some got the app working on 3.5.1?

Same here, not working boeffla config in OSS 3.5.1... The kernel is very good, smooth, but the apk isn't working yet...
Good job bro, your kernel is awesome..

I have a YD206, and it burns almost all the time, it's always uncomfortable to hold despite on mere 5 mins of web browsing. Battery usage always shows Display as the culprit, but that's not what appears to be the cause.
The only fix was to install a kernel manager and underclock the device to 1574 Mhz, to keep the temperatures under check. Just as I was strolling on the Internet and stumbled upon a link to 4pda.ru. However, a dev has forged a kernel with various CPU governors. Here's the link:
https://4pda.ru/forum/index.php?showtopic=797643&st=560
I request anyone here who speaks Russian or is acquainted with the site, to share the information and the kernel so we may also benefit from the rare development on Yotaphone.
Yes it's the old Domnescu's kernel, but it's only for RU Lollipop .134 version. We are waiting that he compiles the one for Marshmallow and I will put it in the guide.
Thank you for the update. Development is extremely rare on this device and custom kernel is definitely a step ahead in controlling system level events of the device, usually not possible through the OS. For example the device could benefit from Undervolting, bringing down temperature and enhancing battery life.
Please do share whenever possible.
Thanks.

I tried no frills CPU Control to underclock CPU but any of versions from GP not recognises root... I am rooted so what góra wrong?

NoFrills does not recognize root. Please try SetCPU, it further offers you the option to assign event based profiles (different CPU frequency tables and governor based on screen state, charge state). It certainly works on Marshmallow 6.0.1. However it's a fix, not a solution, it needs to be implemented through the kernel.
To whom it may interest, I'll attach here the Domnescu's Kernel 1.07 to be used WITH LOLLIPOP RU 134 ONLY. It has multiple governors, schedulers, more files' type support. By the way I read nothing about UV, so I suppose it is not supported in this version.
The .zip with a longer name must be extracted and flashed using fastboot, the other .zip file with a shorter name can be flashed using TWRP or sideloaded.

Thank you for sharing! I'm sure people will find its use as this could be a way to associate different governors with the recent Marshmallow kernel. I'm not sure whether Yota has released the sources for Kernel for Marshmallow. If they have, then we can expect some development soon, else, the longer it takes, the sooner the device would be lost into oblivion.
If someone still uses S6 with Android 6 and wants to test a new kernel there's a link:
https: // github.com/artkar0/SamsungS6_Kernel/raw/master/kernel_artkar.zip
This is the first and also the last version, which I made for my own use.
I compiled it about one year ago and even I don't remember which kernel was used as the base of this mod.
I changed a lot. Process managment, graphics driver, goovernor mods, added really much params to synapse, etc.
I'm still using this kernel on XtreStoLite 3.3.1
Kernel is rather tweaked for battery performance so I recommend turning off cores, reducing frequency, etc. (though these it should work without lags) - in synapse.
