Introduction
Oxygen Kernel is based on stock Samsung source code taken from Samsung Opensource Release Center with sole aim to provide better performance, stablity and battery backup than stock kernel. A kernel tells the hardware in your Android device how to behave, kind of like your mommy tells you how to behave. You can modify how fast your processor runs by over or under clocking it or optimize your system for battery life.
Oxygen Kernel is always up-to-date with latest patches from kernel.org
Known for maximum stability and smooth performance
All the Source Code is available on github

Warning: If you come from some other custom kernel or have any issues, you should dirty flash your ROM before flashing Oxygen Kernel to avoid problems.
Reflash ROM -> Flash Oxygen Kernel --> Flash Magisk if you want to root
If you are upgrading between Oxygen Kernel versions, just flash the kernel zip. Also uninstall or clean data of any kernel control app you're using.
Going back to stock: You can backup your boot.img with TWRP before flashing Oxygen Kernel and restore the backup whenever you want to revert.
1] This kernel removes forced encryption, if you face "encryption process failed" error upon reboot then you need to format /data. This is generally needed if you are installing this kernel on stock tw rom.
2] In OneUI Pie ROMs you may get a warning at boot saying "There's an internal problem with your device". You can safely ignore this warning and causes no harm. It's due to some mismatching KNOX/mobicore stuff. I'll fix it soon.

If you're on stock rom then it should turn on the real flash. If on custom rom then kindly ask the dev to add support in rom

Does it work if u flash back stock kernel? Actually the kennel would not affect camera filters. Maybe check your rom for the act.
can i use this in 6.0?
sorry for stupid quesion . just asking. ty

Version Information
Status: Stable
Current Stable Version: 2.4.2
Current Beta Version: 3.1.0
Created 2017-02-26
Last Updated 2017-07-26
Changelogs
While searching the Internet you might also find versions which aren't listed here: these are Beta versions and their changelog isn't available (but included in the one of the next stable version, so you don't miss anything).
All the changes I made are listed on GitHub.
Version 2.4.2
Code:
- update sdcardfs
- updated build scripts and recovery scripts
- changed toolchain to a better version (Linaro Android gcc 6.3.1)
- widely improved ramdisk scripts
- updated ramdisk to latest version from RR with 7.1.2 support
Changelogs for previous versions:
Version 2.4.0
Code:
- updated with latest Linux patches
- various fixes (including thermal management and network communication)
Version 2.3.0
Code:
I'm constantly working to provide a better kernel. This implies a lot of research, testing and stressing my eyes staring at code. I'm adding a lot of small fixes.
So, try to understand me if I don't always have time to report a changelog.
As always, you can check GitHub for a detailed changelog.
Version 2.2.1
Code:
Sorry if I didn't write down a changelog for the last releases, I've been quite busy.
Anyway: since version 2.1.6b there are a LOT of changes, performance, battery, stability... Just check it out (and check GitHub for a full changelog).
Version 2.1.6b
Code:
- updated busybox and sqlite3 binaries with more convenient versions
- changed optimizations, enabled safety features and possibly fixed f2fs cryptography
- getting ready for the Synapse restyling
- build the kernel uncompressed
The latter fix solves most lagging issues and noticeably improve performance over compressed version; I'll look into the kernel size issue soon!
Version 2.1.5
Code:
- ramdisk rebased over RR's one
- kernel size reduced
Version 2.1.4
Code:
- updated interactive governor with Samsung optimized version
- implemented the AMOLED flicker free patch
- updated ramdisk for both herolte and hero2lte to the one from latest LineageOS builds
- updated ramdisk to be compatible with SlimROM (untested)
- removed a few redundant tweaks
- fireactive it's on its way to debut, but still disabled because incomplete, sorry :(
Version 2.1.2
Code:
- init: added a few tweaks
- ramdisk: changes in sepolicy
- ramdisk: try to fool safetynet and fix wakelocks
- updated to DQBO kernel source
- fstab: reworked mount options
- fs: add exfat support
- fs: implement optimised and stable f2fs (from oneplus/QC8996_N)
- enabled Swap (I had the idea while looking into the OP3 sources)
Version 2.1.0
Code:
Many beta versions came before this one, and all of them had their list of fixes... I'll try to summarize:
- some configs were tweaked
- enabled init.d support
- Synapse support
- implemented elementalx
- various fixes
- faked Knox 0x0 and try to hide from SafetyNet
- switched back to cfq as default scheduler
- probably other stuff I can't remember now... I need to sleep ahahah
Version 1.2.4
Code:
- temporarily reverted to Linux 3.18.14 (and so fixed the video playback issue)
- updated mount options to reduce I/O overhead
- tweaked the kernel configuration to have better performance
- enabled additional compression algorithms and cryptography utilities
Version 1.2.3
Code:
- updated zen sched driver to version 1.1
- SELinux is now set to Permissive by default
Version 1.2.2
Code:
- now using zen as default I/O scheduler
- changed the default frequency range for the CPU
- updated to Linux 3.18.17 (still working to bring the latest patches)
- switched to a custom Makefile optimised for our architecture
Version 1.2.0
Code:
- overclock and underclock support for both CPU and GPU
- voltage control (see notes in the OP [B][**][/B])
- moved to Uber Toolchain 7.x (aarch64-linux-android-7.x)
- improved recovery installation script
Version 1.1.0
Code:
- First public release
[TUTORIAL] How to set up your phone with f2fs
1) First you have to install a compatible recovery. Recent TWRP releases can format and mount f2fs, but they don't handle a few installation scripts correcty. I recommend TWRP 3.0.2-4 by @lyapota which has the correct patches. You can find it here.
2) Then you have to backup all your data (internal storage will be wiped too, so make sure to copy ALL your files in the INTERNAL storage). So, any TWRP backup should be taken on external SD card.
3) After this, reboot into TWRP. From Wipe / Advanced Wipe check only /data, then select Change Filesystem and check f2fs. Do the same for /cache. At the moment I don't think there are ROMs that support f2fs on /system too (LineageOS, for example, forces ext4 and formats despite settings).
4) Reboot into recovery once again, so we're sure that it can mount everything.
5) At this point you're done. Flash your ROM of choice, this kernel, any GApps and whatever you want.
Reboot and profit!
ROMs supporting f2fs formatted /system will be listed here when available.
Awesome. Will this make oasp run better as there based on proper drivers etc? Can this improve the camera? Sorry for questions I have really messed with aosp on s7e yet

The idea is to have more customizations, features and overall a better user experience than the kernel the maintainers of our device provide. The changes I made are listed under features.

Yes. It's a simple .zip that just flashes the kernel (not rooting or anything, but maybe in a future I can upgrade to an aroma installer).

I just posted in another thread regarding use of your kernel
https://forum.xda-developers.com/s7...extended-rom-v3-1-t3559696/page4#post71203867
I had hoped that using your kernel would allow for full functionality of Magisk -- unfortunately it did not
I really think that since Magisk works well with Stock ROMs it has to do with repacking of the boot img
Hopefully you would be willing to touch base with @topjohnwu to work on obtaining full Magisk compatibility with AOSP Galaxy S7 Edge ROMs
Thanks for you work
wow! thanks so much was hoping for a custom kernel for AOSP! i hope you will consider adding undervolting and synapse support. Thanks for your efforts!

The next in my to-do list are underclock and overclock, followed by voltage control.
I flashed it right now on RR . and im impressed as its smooth af. Im not too sure about battery life , but i fully admit its improvement on performence . good job dev . keep it going

Frequently asked questions
1.1 Q: I am having an issue, can you help me?
1.1 A: I am not an amazing kernel developer but I will certainly try my best. First, start by reading the release posts, as I may make note of a particular issue. Also search the thread to see if I have discussed it before. If you see nothing, please provide me with a dmesg/last_kmsg and logcat, your ROM/kernel version, and a detailed description of the issue, following this guide. If I can't reproduce reliably though, I'm not going to fix the issue.
1.2 Q: Can you add xyz feature?
1.2 A: If you link me the commits or tell me what kernel you had the feature in, I can take a look at them. I will not go digging super hard for commits and I will ignore requests that don't include this information. I won't promise that I will merge every request but I will always take it into consideration.
1.3 Q: How do I control the kernel?
1.3 A: I'd recommend using either @flar2's EX Kernel Manager or @Yoinx's Kernel Adiutor-Mod; both are extremely solid and have given me no issues.
1.4 Q: What ROM are you on? What are your settings?
1.4 A: Currently, I am on AICP and my settings are available here here
1.5 Q: OMFG MY BATTERY SUXXXX PLS FIX!!!
1.5 A: The kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone.
1.6 Q: Does it boot in BlackscreenOS ?
1.6 A: I don't know. You can try.
1.8 Q: Can you add Quick Charge support ?
1.8 A: No.
1.9 Q: Bro, i have kate variant, can i use it ?
1.9 A: Of course.
2.0 Q: QC support ?
2.0 A: Don't be ridiculous.
2.2 Q: How about GCC 7 support ?
2.2 A: Currently, GCC 7 cannot be booted on kenzo.
2.3 Q: Why it shows me random max frequencies?
2.3 A: If you're using LOS Based rom is an expected behaviour, don't worry, it won't ruin your performance, is same as before.
2.4 Q: Slow charge bro please fix!
2.4 A: Bro pl0x upd8te fermware.
2.5 Q: Core 6 is offline bro!
2.5 A: Really? wew, enable it and make it default at boot.
2.6 Q: Where i can find you sur?
2.6 A: Either on Telegram(My XDA Username) or G+ sur.

sum moar kenzo kernul pls sur dev
Always happy to see more upstream kernels cropping up around the place
Thanks for this awesome kernel It is a nice thing to see a good developer works on a kernel for redmi note 3. I didnt want to use elementalx cuz of lack of upstream and now you came up with this. And the reason why i dont wanna use other kernels is they have so many patches that dont have a impact on performance in my opinion.
Ty :good:
wew, despacito it's here
Very good kernel :fingers-crossed:
6.4 de
Wow. Great to see you here Aex (oops missed l)
It's amazing
thanks for your work
I got around 2000 ma for charging so that's great and it's faster somehow on Aex rom
don't stop supporting it
Wow. Another kernel for Kenzo. Thank you so much dev. Gonna try this definitely. ?
Wow, nice work, new kernel [emoji7]
Enviado desde mi Redmi Note 3 mediante Tapatalk
Ow nice lets try this on Aosip and rr rom hehe
Thank you so much for this new kernel. Downloading it.
Wew Sur :cyclops:
Hoping for 69 min quick charge and 69hr sot :angel:
*when you want to use AICP but the update frequencies rekt your mobile data*
This is the best solution! Thanks for the new kernel..

Which rom are you using?
Yay, another kernel! Might try this and switch from EX kernel... Keep it up dev/bro!
Support IR? @GeekDragon
Im using RR, but Dominator dont support IR, so i replace the kernel with ElementalX,
Just to use MI Remote,
otherwise i always prefer Stock kernel that Comes with the ROM.

How many users are there in this kernel and what is it with custom ROM?
* Go to User Statistics.
With this kernel, the following information is sent once to the developer's server at boot time.
variant, android serial number(not device serial), name of current firmware(ROM), country code, kernel version
* This information is Android apps can see without any special permissions.
* If you suspect other information transfer, open the '/res/synapse/actions/addon' file.
Description for AOSP ROMs
If you are using another developer's custom kernel, or if using ramdisk is corrupted kernel, you may encounter a bootloop or an unknown problem.
If you have a bootloop problem, flash the PRIME kernel after first flashing the builtin kernel in your ROM. (Or flash the ROM again)
This kernel is flashed AnyKernel method, for all kinds of AOSP ROM support.

Create the '/sdcard(internal storage)/Synapse/do_not_force_install' file.
* MTweak can not support all the features of this kernel.
* Synapse is somewhat unstable, but it is the best solution for a custom kernel.
I have deleted the synapse file with root from the intern sd but there is coming back.
An when i install this kernel the i have no volte icon in the statusbar.

if you create a 'do_not_force_install' file in /sdcard/Synapse folder, Synapse does not install automatically.
the problem with voLTE is that my device is G930K(Korean variant). i can not test for the carriers in all countries.
please try to use v1.3.0 and tell me if it is voLTE.

Hi, I'm GhaithCraft, presenting my custom kernel for Galaxy A7/A5 2017 with tons of tweaks and handy features.
This kernel does not at all drain your battery. (PS: until and unless you don't make some wrong configurations through AKM).
Although this kernel works on custom ROMs it is best optimized for Stock ROMs.

NOTE:This kernel removes forced encryption, if you face "encryption process failed" error upon reboot then you need to format /data. This is generally needed if you are installing this kernel on stock rom
You will need to use AKM(Alphabet Kernel Manager) app to take the most out of the kernel like CPU/GPU overclock, I/O schedulers and plenty of other stuff

Thank you for your work. Can you edit the download link for Alphabet Kernel Manager please? Because it doesn't work.
Nice! Thank you very much! hows the battery life with this kernel? We just need fully working LO Rom and it will be great!.
Hi! First of all: I'm glad to see that the development for this device is not dead!
With that out of the way: Flashed it and it's working great ! Looking forward to future updates !
EDIT: Apply on boot doesn't seem to be working in your kernel manager... I have to set everything manually at every boot :/

Dear folks, today I'm presenting my very own custom kernel for the Galaxy A5 and A7 2017!
This kernel provides many features and a lot of customization.
*To change settings, it's recommended to use HkTweaks by @corsicanu
because it is made especially for Exynos7880 devices. Other apps like kernel adiutor or Mtweaks
do work too, but they may miss some settings.[/CODE]
DISCLAIMER
Code:
*Im NOT responsible for bricked devices, dead SD cards or any damage done to your device.
Compatibility
This kernel is compatible to all variations of A5 2017 and A7 2017.
Only A520F is well tested as I have this device.
Features
Latest A720SKSU5CTL2 kernel release
Linux 3.18.140
Support for AOSP 12, AOSP 11.0, AOSP 10.0, Treble 11.0, Treble 10.0 and Rise-Q

Credits
Thanks to @Option58 for the work on the official lineage sources for our device. Custom-kernels wouldn't be possible without him!
Also thanks to @corsicanu because I integrated some of hadesKernel's features into this kernel.
Thanks to everyone who worked on the features that this kernel contains.

Wow, nice, good job, will try it out!
A520l will try tomorrow
Working Great with pixel experience ROM, I've upped the voltage on GPU and CPUs , Played COD mobile default all is good , used GLtools to get max graphics , and again all is good
Just flashed it. Already encountered a bug, hk keeps on loading. Looking forward on your developments. Good luck
And unlocking the phone through fingerprint seems slower now for some reason. Opening apps is also slower now. Btw im using Google pixel Pie Plus
Flashed it and working good so far. I think you're the first to make a custom AOSP kernel for this phone.
Magisk 20 is working for me, it just takes a few tries to boot sometimes.

Idk, it's all working good for me. Hk is working good too. I am on PE.

Unlocking the phone takes longer because the CPU clocks down on all cores when the screen is off. Therefore it needs longer to unlock. At least this is the explanation that makes the most sense.
That apps are opening slowly sometimes is also a bug I encountered, forgot to mention it in my OP thread. This can be fixed by simply reinstalling/updating the app or doing a clean flash (install ROM, then kernel right after)

You mean hotplug in general or the governor called hotplug?

Hotplug in general
I'm laughing so hard thinking of this title as "Riiiiise and Shiiiine" Project
Good work btw
With crDroid and this kernel, I got 106k in antutu. I love the fast charging too. Such an upgrade compared to "stock" aosp.
Latecomer... flashed and rebooted first time on Magisk 20 using crDroid
Going to have a play with some features and report back if I find anything useful.
Thanks Simon

97117 for me. Going to tinker then have another go. Best score I've ever had on this device though.
Replacing the device soon though

So far so good. Been trying some settings I had on my Xperia SP about 4 years ago and they seem to be working well for a balance of performance and battery.
Simply put:
CPU governor - Interactive (max and min frequencies set at maximum and minimum accordingly)
I/O scheduler - Fiops with Internal Storage read ahead set to 1024KB
I/O scheduler - bfq with External storage read ahead set to 1024KB
No CPU hotplug (really only useful for stock Sammy kernel)
That's it
Feel free to try and report back with your own findings.
I'm finding little lag now (was getting some really big lags and micro freezes) and battery draining slower

My results was with GPU overvoltaged and no apps other than hKtweaks, magisk and antutu. So hardly real world.
