- + the 5or6 that are there with FXP
Lulzactive - Thanks to Tegrak
Based on Interactive and Smartass. 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
Virtuous
Virtuous is a modded smartassV2 which gives even more battery time then smartassV2
Intellidemand - Thanks to faux123
This is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling,
and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such.
Intellidemand does not jump to highest frequency when screen is off.
Lazy - Thanks to Ezekeel
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 overriding sampling interval.
Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always
select the maximum frequency while the screen is off.
-Ondemandx:
Basically an ondemand with suspend/wake profiles. This governor is supposed to be a battery friendly ondemand. When screen is off, max frequency is capped at 500 mhz. Even though ondemand is the default governor in many kernel and is considered safe/stable, the support for ondemand/ondemandX depends on CPU capability to do fast frequency switching which are very low latency frequency transitions. I have read somewhere that the performance of ondemand/ondemandx were significantly varying for different i/o schedulers. This is not true for most of the other governors. I personally feel ondemand/ondemandx goes best with SIO I/O scheduler.
-Lionheart:
Is a conservative-based governor. The tunables (such as the thresholds and sampling rate) were changed so the governor behaves more like the performance one, at the cost of battery as the scaling is very aggressive.
To 'experience' Lionheart using conservative, try these tweaks:
sampling_rate:10000 or 20000 or 50000, whichever you feel is safer. (transition latency of the CPU is something below 10ms/10,000uS hence using 10,000 might not be safe).
up_threshold:60
down_threshold:30
freq_step:5
Lionheart goes well with deadline i/o scheduler. When it comes to smoothness (not considering battery drain), a tuned conservative delivers more as compared to a tuned ondemand.
BadAss Governor:
Badass removes all of this "fast peaking" to the max frequency. Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1024Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.
Superbad -
A "superbad" super smooth rendition of a highly optimized "smartass" governor!
Darkside -
A "slightly more agressive smart" optimized governor!
Intellidemand2 - Thanks to faux123 and CosmicDan for mods
Uses d_bus ramping, quick and smooth and performance based, do not complain about battery drain on this
governor but it will make everything feel more like project butter
What else-----
-SLQB - (SLAB allocator with Queue)
This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate).
- Alot of changes to code to try improve smoothness ect
- Wifi signal lock on should now be quicker / stronger then before

VM tweaks (explained below)
VM Tweaks
dirty ratio and dirty background ratio 1 & 2
This controls how often the kernel writes data to "disk" (in our case the internal microSD system card, not the removable microSD card). When your apps write data to disk, Linux actually doesn't write the data out to the disk right away, it actually writes the stuff to system memory and the kernel handles when and how the data is actually going to be flushed to the disk. These values represent a percentage, the higher the percentage, the longer it waits to flush, the lower the percentage, the more often flushes will occur. Now remember, we are dealing with solid state storage, not the traditional disk platter and spindle. So we are actually able to delay flushes a little longer with solid state versus a traditional hard drive disk.
dirty_expire_centisecs
How old "dirty" data should be before the kernel considers it old enough to be written to disk. It is expressed in 100ths of a second.
dirty_writeback_centisecs
This is the interval of when the writeback daemons periodically wake up and write "old" data out to disk. It is expressed in 100ths of a second.
min free kbytes
This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a pages_min value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size. Default is 2048kb.
overcommit_memory
This controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.
0 - Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slighly more memory in this mode. This is the default.
1 - Always overcommit. Appropriate for some scientific applications.
2 - Don't overcommit. The total address space commit for the system is not permitted to exceed swap plus a configurable percentage (default is 50) of physical RAM. Depending on the percentage you use, in most situations this means a process will not be killed while attempting to use already-allocated memory but will receive errors on memory allocation as appropriate.
Swappiness
A property for the Linux kernel that changes the balance between swapping out runtime memory, as opposed to dropping pages from the system page cache. Swappiness can be set to values between 0 and 100 inclusive. A low value means the kernel will try to avoid swapping as much as possible where a higher value instead will make the kernel aggressively try to use swap space.
VFS Cache Pressure
File system cache (dentry/inode) is really more important than the block cache above in dirty ratio and dirty background ratio, so we really want the kernel to use up much more of the RAM for file system cache, this will increas the performance of the system without sacrificing performance at the application level. The default value is 100, as a percentage, and what you want to do is lower the value to tell the kernel to favor the file system cache and not drop them aggressively.

testing...
(thx for your effort sofar :good
1st impression: lower scores on Antatu than with standard PAC-kernel.
i'd like to have a better battery life, so now testing "virtuous/sio, 806/134".
or are there better suggestions?
(like to keep a snappy Ray )
"Custom voltage control supported" not working. The PAC romcontrol says: not supported by your kernel

I don't think that part of RC has been activated....it also doesn't work with the kernel from champilnswimmsr's aokp build. I am using incredicontrol from the play store...but a lot of other apps will let you change the volts.

is there a list of recommended (or safe) voltage settings for the Ray?
Yes i know in rom control it still says not supported not sure why but u can always use SetXperia app from playstore to change it
And poster who asked about safe settings. Try down step -25mv at a time and see what is stable for you. If u get reboots then its obviously not stable.
Or else safest way if your wortied then dont undervolt at all. What maybe stable for someone might not be stable for you

I tryed thi kernel for my CM10 rom. And it seems buggy. Antutu points is lower than on stock kernel, and the perfomance is bad too, including games and UI.

lol ok first off this is not stock kernel so you can't compare it to STOCK,Ssecondly i'm not sure what governors, io scheds and frequencies you are using. People who have tested have reported it being smooth and performance being greater not worse. Also I obviously use my own kernels on my own device and my experience is the complete opposite of yours. You sure it not 'your' CM10 rom. Buggy!! how? please do elaborate.
Anyone else confirm what the above pster has said ??
Using it now for some hours with Virtous and SIO and looks very promising. Speed of ROM is for me the same and I dont play games. But Battery seems to be great! I left the screen off a lot and have like 95% deep sleep, so pretty well battery ;D I use FXP142.
EDIT: just tested the game "granny smith'. Runs good! But I didnt test with another kernel.

Ye virtuous is supposed to be more battery friendly then smartassv2
Intellidemand2 would be best performanced based but not the best on battery.

Thanks for the great kernel, really liking the Superbad governor.
I left my ray on during the night, to see what the battery would do...
(i mean screen off, but wifi+3g on)
from 100 to 74% in 9 hours.
8:40 deep sleep (94%)
806/134 virtuous/sio
I cannot compare btw, usually i charge at nighttime, but usage seems quite high?
was hoping for about 90% battery left or something, but like i said, not tested with other kernels.
I think I caught a "wifi" bug. Yesterday the wifi cut out and wouldn't turn back on...after rebooting everything was fine for a few hours and then wifi stopped working. I am not sure if it is really wifi or something else, because if I go into settings I see that wifi is on, I can turn it off but it won't turn back on...if I leave settings and pull down the status bar it show wifi as "on"...when I go back into settings it shows wifi as "on"...and no networks are shown that can be connected. You can do this over and over and every time you reenter settings it says wifi is on. I think it also causes a wakelock from wifestatemanager.
I went into recovery and formatted system and reinstalled PACman v15...a few hours later the problem returned. I flashed in a different kernel and it seemed OK....now I have your kernel on ChampionSwimmer's AOKP ROM and I am waiting to see if the bug returns.
I am not sure if there is something specific I do that activates the bug, so I don't have a logcat of it happening. I attached a logcat of me trying to turn on and off wifi in settings. I also attached the battery stats report from Better Battery Stats in case the wakelock is informative....
Be Sure ! If you benefit to the other's you will see it's effect.

Battery tips&tricks
This post will update with your informations and experiences about battery saving
[MOD] LCD TWEAKS (FPS - RESOLUTION) for Better Battery Life
[MOD] Lower AutoBrightness Values
[GUIDE] 'AUTOBOTS' Kernel Settings [Gabriel kernel] [Battery Life]
MODEM
The modem act as the Software bridge between the RIL driver and your phones Hardware (correct me if i am wrong)
Because of that you can directly (more or less) control how your phone signal is behaving by trying different Modems till you find one that suits your needs.
The modem images does have an impact on wifi, mobile networks and how fast they are able to scale up or down, battery runtime, as well as call quality sometimes.
While the g3 got a good signal most of the time the changes might not be this big, compared to other phones and their modem differences, but it is still a good thing to know you got the best reception possible
For me the 20A and 20p Modems are working better then the most others... But there will be people with other carriers etc for whose another might be the right!

i like the 268mhz cpu step and gpu 27idle.
i missed that when i switched phones from oneplus to lg g3. thanks for the kernel will install.
i guess i can just flash it over my chupachups kernel?
What governors are in this Kernel?
Does not work with 20p, it restarts the phone all the time.

No worry about the governors. I flashed it haha. Working nicely with cloudy 2.2 so far. Not been long of course. Any recommended settings for battery life?
I'm set on Fiops, 2048 read ahead, smartmax eps, 300000 Max off screen, 2.5ghz Max clock, simple on demand GPU, under clocked to 330. And some other bits I think.

Weirdly the smartmax and smartmax eps governors don't seem to be very battery friendly lol.
On engines kernel Lionheart was good when on paper it shouldnt really be but Wheatley and DanceDance were bad when they should of been good. I don't get it?
Introduction
This is a kernel for XT1572/XT1575 built from stock sources (marshmallow-6.0.0-release branch) with cherry picks from other kernels and some ports/mods done by me. It started as a personal build tailored to my preferences but just thought I'd share in case somebody might find it useful. My main goal is building the smoothest kernel I can get so performance is top priority.
This kernel is for stock ROM MPH24.49-18*
Disclaimer
Although I have experience with Linux kernels on desktops and servers this is my first Android kernel. I've been running this kernel on my XT1572 for a few days and seems pretty stable but that doesn't mean it's risk free. In fact I wouldn't dare to install it if you don't have a proper backup and some basic skills to deal with unexpected situations.

Download ZIP and flash from TWRP/Flashify. Read the following notes carefully before flashing.
Important notes:
This kernel is still experimental, make a proper backup first
You need to be rooted
DO NOT play with DT2W/S2W before reading the release notes and the update
In case you want to tune some parameters (ie: CPU frecuencies) I recommend you install EX Kernel Manager, Kernel Adiutor or Kernel Adiutor-Mod.
If you're using Kernel Adiutor to control vibration or TCP congestion read this.

Donations
Although quite a deal of the important work has been done by the developers mentioned in the Credits section I spend many hours working on this. If you feel like helping me out I'd appreciate some tiny donations to cover some minor expenses.
Thanks to all of you who have donated, it's very much appreciated.
Profiles
One of the FAQ in most kernel related threads is "What are the best settings for .....?". This is the 10 million question since the usage pattern can be very different for each user. However, I understand less experienced users will appreciate some hints in this department, so that's why I'm posting some basic settings you can use as a starting point.
It's your job to further tune them to suit your needs. You should be able to modify these settings with whatever Kernel Control App you like the best, although not all settings are available in every app, in such a case tune those you can. The list is not complete (just the most importante settings) and is loosely based on Kernel Adiutor arrangement.
Please, keep in mind these are subjective values (based of personal preferences or popularity) and some people might like other settings for whatever reasons.

FAQ
I get random reboots, what is happening?
This kernel overclocks both clusters by default (a53: 1536MHz a57:2016MHz) and although this is very safe for most devices some CPUs are in the lowest spot of the binning spectrum and can't handle O/C very well. In such a case use a kernel control app (see the OP for references) to limit the maximum CPU frequencies, play with them until you find stable values for your device.
What are the best settings for battery life/performance/whatever?
That's hard to tell as every user is different. You can find some basic profiles in the OP you can use as a starting point. Notice the differences between then and build you own.
Why do some BIG cluster settings display N/A?
Why can't I change some settings on the BIG cluster?
If you get N/A or weird values when trying to change settings on BIG cores it means both are offline ("hotunplugged"). To work around this select "performance" governor, make your desired changes and then select you previous governor. You can also disable hotplug, make the changes, and enable hotplug again.
DoubleTap2Wake doesn't work sometimes. How can I get it to work all the time?
When device goes into suspend mode first tap is often missed (I suspect this is caused by Moto Sensor Hub). If you tap three times and get the timing right you'll probably make it work most of the time. As an alternative, Sweep2Wake works almost all the time
DT2W/S2W is acting weird or disabling itself
Make sure Moto Display is disabled. Open the Moto app, click on the stars in the top right corner, select Display and set to Off
Can I use this kernel in ROM X/Y/Z?
This is for stock ROM MPH24.49-18 only. It'll probably work on any stock based ROM but not guaranteed.
I use stock ROM but WiFi is not working
Due to some internal changes all modules had to be recompiled (WiFi included). In order to expose the new modules without modifying the system partition I had to implement a hack that requires root. Make sure you're properly rooted.
What's the deal with ZRAM?
ZRAM is a technique to increase memory available to the apps at the expense of CPU time. Memory space from apps not being used is compressed into a memory swap area and uncompressed on the fly whenever needed. As you can imagine this compress/uncompress process burns CPU cycles, potentially leading to worse battery life, lag and higher temperatures. Since this device comes with 3GB I can only think of one scenario where ZRAM can be beneficial: heavy multitaskers who care more about apps not reloading than battery life. For the rest of users enabling ZRAM doesn't make much sense in my opinion, and that's why it's disabled by default.
UPDATE: v0.10 includes an updated ZRAM driver that improves performance significantly. So much so that the benefits seem to outweigh the costs and it's been enabled by default.
What's the deal with KSM/UKSM?
Since many apps use the same libraries/resources it's very likely that at any given time there are multiple copies of the same data on different memory locations. KSM/UKSM tries to take advantage of that fact by scanning memory pages periodically and consolidating that multiple copies into a single shared copy. Much as like ZRAM it can have a good effect on heavy multitasking performance but at the expense of CPU cycles, and thus it's only recommended in the same scenario as ZRAM. Disabled by default
Ok, so do I enable ZRAM/KSM/both/neither?
I honestly think most users will be better off not using neither. If you feel like you need extra RAM I'd try KSM first, then ZRAM. Using both at the same time is overkill unless you are an ultra multitasker, in which case you should probably get a 4GB device anyway
How do I get WiFi on 6.0.1?
It's a modem version mismatch issue, you need to downgrade the modem. See this post.
Love to see more options! Thanks for sharing!!
Yeah this will be very good
Only One think that would be awesome try to implement the double tap to wake

As I said on the OP my main goal is performance/smoothness, so I haven't specifically sought better battery life. That being said I'm getting about the same battery life as stock with better performance, that works for me.
Nevertheless, I'm very interested on how it works for other configurations and usage patterns.
@dirtyhank could you please add hotplugging to the kernel? Preferably one that allows you to select how many cores to run as well as which ones, as in run the two A57s and turn off the four A53s. Currently I'm running two A53s at 1.2Ghz and the remaining four cores are always off.
The screenshot is from Lolipop, and it is the only reason why I havent upgraded to MM. Turning off cores definitely makes a difference on battery life.
Also, if possible, adding a lower speed to the min speed. Will gladly test anything you thow my way. Thanks in advance.
Is there any chance for a CM13 version and a DT2W fork from elementalx?

FAQ
Q: With which ROMs this Kernel is 100 % Compatible ?
A: Currently only with Android 9 custom ROMs, but Samsung stock ROM is recommended.
Q: Is this Kernel 100 % Safe ?
A: Yes.
Q: Will this Kernel Overheat the Phone if I use Highest Settings ?
A: No, you can't do anything wrong. Your phone has hard- and software overheat protection.
Q: How to Revert all Changes Made by this Kernel ?
A: Flash latest 3-parted stock ROM with ODIN or flash the Samsung kernel from my download site.
Q: How to bypass SafetyNet ?
A: Anable MagiskHide in Magisk app.
Q: How i can Tune this Kernel ??
A: Everytime you install or update this kernel you will face an red (demo) app "A2N Kernel Control..." open this app, and it'll redirect you to Google Play to get the full version (blue app).
Q: Can i use and Tune your Kernel with other Kernel Manager Apps ?
A: Yes, but you need first to unlock kernel with the A2N app full version.
Q: I've Installed the Full Version of the App, Will it Change any Kernel Settings by Default if i do not Change them ?
A: No, default app settings = default kernel settings.
Q: I've the Full Version of the A2N Kernel Control App, Do i still need the Demo Version of the App ?
A: Yes, there are some special features in-app-menu like "Fake Enforce" and debugging features for easy bug reports.
Q: How to Charge from 10 % to 100 % In just 1 h ?
A: E.g. set "AC Current Max" and "Maximum Charging Temperature" to the Max.
Q: How to get Max Speed for e.g. Highest FPS in Games ?
A: Set BIG / LITTLE CPU and GPU Freq to the Max, but avoid to use "unsafe" Freq's.
Then set CPU / GPU --> DVFS --> "Maximum Temperature" to the Max.
Now you can even cook an egg on your phone !
Q: Will my Custom A2N Settings Survive if i install Stock Kernel and then going back to A2N Kernel ?
A: Yes, as long as you don't uninstall it.
Q: Can i use your Kernel Control App with other Custom Kernels ?
A: No, it's not universal kernel manager app.
Q: My A2N App is Crashing after an Update, how to fix it ?
A: Re-install it. If it doesn't help, wipe dalvik-cache in recovery.
Q: My A2N App shows: "Please check your internet connection" - But i've good internet connection. - How to fix it ?
A: Settings --> network settings --> use private DNS server like "dns.adguard.com" - confirmed to work by user @Arnz09 - see his post here.
Otherwise send me a pm with the screenshot and you current location (city)
Q: Why I get lower benchmark scores with this kernel compared with the Samsung kernel ?
A: This kernel uses by default Max CPU/GPU DVFS Temp 65 °C to reduce the device heat. You can buy the full version of the A2N app to set the DVFS Temp up to 100 °C to get higher scores than on stock kernel.
Q: Why the Android Battery setting "fast charging" has no effect on this kernel ? - It charges always with around 1500 mA.
A: Because it would conflict with the built-in charger control.
The default charging current of approx. 1500 mA means no fast charging by default, even if you actually see "fast charging" in the notification section. This is also useful to reduce battery stress and device heat. To charge even with higher speed/current than on stock kernel you need to buy the full version of the A2N app.
Q: Why I've to pay money for just changing kernel settings ?
A: Well quality has its price. Also nobody forces you to use this kernel.
You can flash other custom kernels or flash the Samsung stock kernel from my download site. Good luck !
Q: When we get an update ?
A: This kernel is almost 100 % stable and works very well. Also this phone is now a bit "old" and therefore don't expect frequent updates.
Also don't ask for ETA's and if you do anyway, I'll ignore.
Q: How to fix audio stutering ?
A: Increase the PM-QOS-LIT / PM-QOS-BIG Freq in A2N app in debug menu --> "Audio" section.
Q: What is the benefit of editing the voltage table ?
A: to increase OC stability increase voltage and to decrease the device heat, decrease voltage. Last one will improve performance due to less throttling ! So it depends on your needs.
Q: How much is safe to undervolt ?
A: approx -50 mV is considered to be "safe".
Q: How to Report Bugs ?
- Please DO NOT report bugs if you are:
--- using "unsafe" Freqs
--- not using the latest release !
--- not using Samsung stock ROM (based stock ROMs are custom ROMs !)
A: Open the red A2N Kernel Control demo app and check in-app-menu (3 dots) then "Debug" and then on "logcat and dmesg" if you faced an app crash or if some features didn't work.
If the phone rebooted randomly, then tap on "last_kmsg". You will find the logs in your internal storage. After that you can attach them here in your bug report, by clicking "Attach files".

Play playstore app support only galaxy ace 2 ?
unfortunately something went wrong with the s8 app release.
need to contact Google later.
please be patient.
are u going to release a version for sm-g955f? your kernel sounds rly interesting would appreciate that.
thanks! maybe yes ... if many users want it.
G95/ g955/ f/ n？
For now it's only for G950F and only tested to work 100% stable with the CRGH Build.
Tested for very long time on my G950F.
Honestly i don't like to build software for a device i don't own .. and even not to mention to release Software without to test it on my own.
However if'll receive positive Feedback then i'll buy all S8 Variants in order to build a perfect Kernel for you Guys !
But for now lets start with this.
I'll test and update this Kernel on latest available Stock ROM...
So, stay tuned
Thank you very much, I will continue to pay attention to it. I am G955N.
I have s8+ g955f. I know that it is only for s8 but anyway, I tried to test the kernel, it is booting up but I have no touch screen. I would be more than happy to test any test build if you decide to make it for s8+ too in the future.
Στάλθηκε από το SM-G955F μου χρησιμοποιώντας Tapatalk
installed with rom deodex ambasadii deo mod v1.3 and it works perfectly, only with mtweaks I can not regulate much, especially the battery current, moreover, why is there only interactive and deadline scheduler? another interesting feature is the dex only with the cable, I have to buy it so I try it, great job, when the app comes out in the play store I try it better, now I want to test consumption.
@ace2nutzer could you send me the apk of the kernel controller in trial version on telegram, my nikname is @ pablonik79
I really cant wait to use it on s8+. Thx for your efforts #respectthedevs
G955f not available?
If the kernel I only for s8 variant it shouldn't be posted on cross device topic....I think?
But anyway, nice futures so it'll be nice to have a new alternative for both devices. There's not much development in s8/+ especially from kernel side.
Thx for your work
installed this kernel on my s8 g950fd，my sd card cant be identified

This Kernel is optimized to work best with the Stock ROM, but it's nice to hear that it works as well with custom ROM.
only with mtweaks I can not regulate much, especially the battery current,
Click to expand...
Click to collapse
Yeah that's normal it's a fully optimized custom Kernel, all features works only with the original Kernel Control App from me. Using such "Universal" Kernel Manager Apps can even make your Phone unstable and will not make things better. That's why i build for every Device // Kernel a separate Kernel Control App.
Otherwise i would build also an Universal Kernel App ... but it's not that efficient and this is what u Guys definitely don't want for sure.
moreover, why is there only interactive and deadline scheduler?
Click to expand...
Click to collapse
Because we only need one good working CPU Governor and I/O Scheduler ... right ?
Short and easy explanation:
Interactive: it's the perfect gov for low latency workloads. - So it's perfect for Android to have a smooth and quick response experience.
Deadline: It's optimized for Flash Devices, it's simple and stable - Also appropriate for Android.
All other Gov and I/O are unstable or will decrease the Performance and or battery lifetime ...
(at least not very appropriate for Android .... however there's also I/O sched "ROW" or "FIOPS" which would be also ok for android, but they are not that stable like "deadline" and the difference in I/O Performance isn't that much.
So i've removed them so that u Guys can't change (accidentally) this important Drivers.
when the app comes out in the play store I try it better, now I want to test consumption.
Click to expand...
Click to collapse
G950 App comes hopefully Today out .. unless Google will block it again.
could you send me the apk of the kernel controller in trial version on telegram, my nikname is @ pablonik79
Click to expand...
Click to collapse
Sorry, there's no Trial Version at all ... only the Demo u can find in the Kernel Package.
But i know, u can't Tweak anything.... Please wait for the full Version.
Thank u very much Guys for your Appreciation. :good:

FAQ
Q: With which ROMs this Kernel is 100 % Compatible ?
A: Currently only with Android 9 custom ROMs, but Samsung stock ROM is recommended.
Q: Is this Kernel 100 % Safe ?
A: Yes.
Q: Will this Kernel Overheat the Phone if I use Highest Settings ?
A: No, you can't do anything wrong. Your phone has hard- and software overheat protection.
Q: How to Revert all Changes Made by this Kernel ?
A: Flash latest 3-parted stock ROM with ODIN or flash the Samsung kernel from my download site.
Q: How to bypass SafetyNet ?
A: Anable MagiskHide in Magisk app.
Q: How i can Tune this Kernel ??
A: Everytime you install or update this kernel you will face an red (demo) app "A2N Kernel Control..." open this app, and it'll redirect you to Google Play to get the full version (blue app).
Q: Can i use and Tune your Kernel with other Kernel Manager Apps ?
A: Yes, but you need first to unlock kernel with the A2N app full version.
Q: I've Installed the Full Version of the App, Will it Change any Kernel Settings by Default if i do not Change them ?
A: No, default app settings = default kernel settings.
Q: I've the Full Version of the A2N Kernel Control App, Do i still need the Demo Version of the App ?
A: Yes, there are some special features in-app-menu like "Fake Enforce" and debugging features for easy bug reports.
Q: How to Charge from 10 % to 100 % In just 1 h ?
A: E.g. set "AC Current Max" and "Maximum Charging Temperature" to the Max.
Q: How to get Max Speed for e.g. Highest FPS in Games ?
A: Set BIG / LITTLE CPU and GPU Freq to the Max, but avoid to use "unsafe" Freq's.
Then set CPU / GPU --> DVFS --> "Maximum Temperature" to the Max.
Now you can even cook an egg on your phone !
Q: Will my Custom A2N Settings Survive if i install Stock Kernel and then going back to A2N Kernel ?
A: Yes, as long as you don't uninstall it.
Q: Can i use your Kernel Control App with other Custom Kernels ?
A: No, it's not universal kernel manager app.
Q: My A2N App is Crashing after an Update, how to fix it ?
A: Re-install it. If it doesn't help, wipe dalvik-cache in recovery.
Q: My A2N App shows: "Please check your internet connection" - But i've good internet connection. - How to fix it ?
A: Settings --> network settings --> use private DNS server like "dns.adguard.com" - confirmed to work by user @Arnz09 - see his post here.
Otherwise send me a pm with the screenshot and you current location (city)
Q: Why I get lower benchmark scores with this kernel compared with the Samsung kernel ?
A: This kernel uses by default Max CPU/GPU DVFS Temp 65 °C to reduce the device heat. You can buy the full version of the A2N app to set the DVFS Temp up to 100 °C to get higher scores than on stock kernel.
Q: Why the Android Battery setting "fast charging" has no effect on this kernel ? - It charges always with around 1500 mA.
A: Because it would conflict with the built-in charger control.
The default charging current of approx. 1500 mA means no fast charging by default, even if you actually see "fast charging" in the notification section. This is also useful to reduce battery stress and device heat. To charge even with higher speed/current than on stock kernel you need to buy the full version of the A2N app.
Q: Why I've to pay money for just changing kernel settings ?
A: Well quality has its price. Also nobody forces you to use this kernel.
You can flash other custom kernels or flash the Samsung stock kernel from my download site. Good luck !
Q: When we get an update ?
A: This kernel is almost 100 % stable and works very well. Also this phone is now a bit "old" and therefore don't expect frequent updates.
Also don't ask for ETA's and if you do anyway, I'll ignore.
Q: How to fix audio stutering ?
A: Increase the PM-QOS-LIT / PM-QOS-BIG Freq in A2N app in debug menu --> "Audio" section.
Q: What is the benefit of editing the voltage table ?
A: to increase OC stability increase voltage and to decrease the device heat, decrease voltage. Last one will improve performance due to less throttling ! So it depends on your needs.
Q: How much is safe to undervolt ?
A: approx -50 mV is considered to be "safe".
Q: How to Report Bugs ?
- Please DO NOT report bugs if you are:
--- using "unsafe" Freqs
--- not using the latest release !
--- not using Samsung stock ROM (based stock ROMs are custom ROMs !)
A: Open the red A2N Kernel Control demo app and check in-app-menu (3 dots) then "Debug" and then on "logcat and dmesg" if you faced an app crash or if some features didn't work.
If the phone rebooted randomly, then tap on "last_kmsg". You will find the logs in your internal storage. After that you can attach them here in your bug report, by clicking "Attach files".

BUG REPORTS THAT DO NOT FOLLOW THESE RULES WILL BE IGNORED !!!
is root necessary for this kernel to work?
Not mandatory if you are ok with kernel defaults, otherwise you will need to root your phone if you want to change kernel settings.
Root (Magisk) can be flashed anytime on top, without problems.

I attempted for Note8 in HadesRom v2.0 so mobile phone froze on samsung login screen and it didn't turn on.
Anyone else having problems?

It work only with android 9 hades room its not android 9, it work for me
Do I need to toggle something for higher resolution in Dex? I only get FHD with Dex station and 3840x1600 monitor.
@ up
First you need to change screen resolution in your phone.
Change from FHD to WQHD.
@ all
Nice to know that it works guys ! - As i don't have an Note8, but S8.
As you can see in changelogs and as well in S8 development sub-forum, this in an old project for the S8/S8+ and finally i'd the time to add support for Note8 as well.
Motivation was literally one year ago as @VoLTaqe asked me if i could add support for Note8 since it's the same platform, with some small differences.
Btw: if you are running this kernel, please post the output of:
Code:
free -m
# and
cat /proc/meminfo
Since Note8 has different RAM size, so i can adapt the zRam(swap) script. Also you should get a few extra MB RAM since i've optimized RAM partition, or better say cleaned up some useless reserved regions in RAM.
Like this? I'm using hades Pie if that's important.

Change from FHD to WQHD.

Thanks but it didn't help. WQHD is still grayed out in Dex. I have never got WQHD to work in Dex so maybe Dex doesn't like my monitor.
Alright, thanks !
Unfortunately i can't test Dex at all, but i'll check the source code.
So that meminfo output is with this kernel installed ?

Yes, hades Pie with this A2N kernel.
I'm using hades Q , will it work completely 100% or it will work but not everything or it won't work at all ?
Sorry for my english
Sorry bro, but it won't work at all.
Actually it's only for Android 9.
Just in case, how can I return to stock kernel without reflashing the whole stock rom?
and how does the default setting's battery life compare to stock? thanks.

Note8 - stock kernel - DUG6 - fully patched.
It can be flashed over A2N kernel without any wipes.
Later when you are tired of stock kernel, you can re-flash again A2N kernel over it without to wipe anything.

No idea as i don't have Note8.
But in theory it should be better. At least it's true for S8 compared with Samsung stock kernel.
Hi guys ! - I've uploaded an test kernel for Note8.
Please flash it, boot to Android and post the output of:
Code:
uname -r
free -m
cat /proc/meminfo
Run the cmds in ADB or directly in your phone using "terminal emulator" app.
I'm working on new release with better memory management and improved stability.
Stay tuned !
