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
Kernel Info
LINUX: 4.4.182
SAFETYNET: Green
TOOLCHAIN: Linaro 7.4.1
SELINUX: Enforcing (on ONEUI only) (You can change to permissive using Oxygen Control app)
Compatible ROMS
All OneUI Pie based ROMs
All treble GSI ROMs
Features
Here are the major features of the kernel (feel free to explore Github)
Up to date with the latest stable Linux version
Disabled TIMA, KNOX, DM-VERITY,etc
Awesome battery life and optimised for smooth performance
O3 optimisation
Tuned for cortex-a73 and cortex-a53
Advanced SIMD and floating-point instructions, CRC and Crypto extensions
CPU Governors: conservative, interactive, ondemand, performance, powersave, userspace and many more (default: interactive)
I/O Schedulers: bfq, cfq, deadline, maple, noop and many more (default: maple)
Powersuspend and State Notifier drivers
Dynamic FSync, FS fsync toggle on/off
Spectrum Support (a simple, profile based kernel manager || now integrated into Oxygen Control)
Disabled CRCs by default for 30% performance boost
Patched for DriveDroid support
Wireguard support
Boeffla Wakelock Blocker
Overclocked and underclocked the CPU. Take a look at the new max/min freq below.
BIG Core LITTLE Core
MAX: 2.2GHz MAX: 1.7GHz
MIN: 312MHZ MIN: 208MHz
Oxygen Control App Features
Proper support for Exynos7885
Full CPU and GPU Control
Boeffla Wakelock Blocker
Spectrum Support
Fsync, CRC Control
Selinux toggle
And many more!
These features are only available through Oxygen Control App
Download Oxygen Control from Github Releases
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.
This kernel removes forced encryption, if you face "encryption process failed" error upon reboot then you need to format /data.

No, screen gestures aren't supported as of now.
Re-uploaded TREBLE-GSI builds with permissive SELINUX by default. This fixes bootloop issues on some GSIs. Download the new builds and install again for the Oxygen experience.
Thanks
What is the difference between Oxygen Kernel v1.0 and Quantum Kernel v3.0? I have installed Quantum Kernel v3.0. If I do restore to a stock kernel, can I install this Oxygen Kernel v1.0? SM-A530F.

Oxygen kernel has almost everything that quantum has along with additional optimisation like latest linux patches, special optimisation for our soc, overclock, better underclock, etc. I've developed this kernel in collaboration with the developer of Quantum Kernel.
Yes you can restore to stock kernel and then install oxygen.

I tried every combination i could think of after following instructions twice. I don't mind wiping or starting from scratch. It's the constant failure. Grr. It appears to not be variant specific.
I can't even re-size partitions in TWRP anymore. Haven't tried since around January. That is unrelated, though.
I would like to know what this was tested on and are there any successful installs with this?
Whatever the problem, i'm hoping to give this a try soon.

I'm aware of the issue now. Seams it's only on A8 and not on A8+ and my tester has A8+. I'll fix this issue soon.

Kernel features:
Build with custom toolchain blu_naro-7.3 (cortex-a57 targeted, build with latest Crosstool-NG from developer snapshot Linaro GCC 7.3-2018.04)
Full -O2 build with device and target flags enhanced, linaro build improvements, etc
Less is more: stockish OP3/OP3T unified builds based on OnePlusOSS/android_kernel_oneplus_msm8996
Systemless installer (doesn't touch system partition, OTA friendly - Nougat only)
Removed some debug and logging options
ARM enhanced performance and battery patches
CVE security patches, general upstream and CAF fixes
Several CPU Governors (blu_active modded own governor by default - fastlane mode available!)
No OC, set 300HZ base timer frequency
msm_performance input boost toggle on/off (enabled by default), tweaked cpu_boost driver
Enhanced TCP methods (westwood is default), Network and Wifi tweaks and updated drivers
Several I/O control tweaks, added schedulers FIOPS and ZEN v2 is default, tweaked and upstreamed filesystems (F2FS, ExFAT, NTFS & CIFS)
Removed verify and forced encryption, Set androidboot.verifiedbootstate=green
Stock thermal driver by default (custom tunables available for ROMs with no thermal daemon)
Disabled hotplug on low battery levels
Optimized crypto routines
Swap and adaptive LMK off by default, 60 apps on background by default
Vibrator Strength tunable and Gesture Haptic Feedback control (touchpanel)
KGSL fixes and reworked GPU driver (use 133MHz min freq to save juice, goes to idle @ 100MHz)
sRGB and KCAL - Advanced color control for Qualcomm MDSS v2 (RGB calibration and post-processing features)
DASH charge and USB Fast Charge (USB mode up to 900mA with MTP on)
Battery/Notification LED control
FS fsync toggle on/off
Wakelock blockers available
zx2c4's wireguard support
CDROM emulation on mass_storage (compatible with DriveDroid 0.10.36+)
init.d support (put your scripts in /system/su.d or /su.su.d [systemless SuperSU], /magisk/.core/post-fs-data.d [Magisk])
Compatible with Kernel Adiutor and others
DOWNLOAD KERNEL ZIP and RECOVERY (No mirrors please)
Warning: If you come from other kernel or have any issues, you should dirty flash your ROM before flashing blu_spark zip to avoid problems.
Reflash ROM -> if you want root flash SuperSU or Magisk (default, no plugins/modules) -> flash blu_spark.
If you are already rooted or upgrading between blu_spark versions, just flash the kernel zip. Also uninstall or clean data of any kernel control app you're using.
Builds for OP3/3T are unified (so can be flashed in both devices).
About bugs and troubleshoots: don't bother to post if a log isn't ready or without steps so the behavior can be replicated. I only active support stock OOS with NO mods whatsoever (apart from root). That includes NO support if using xposed, Magisk with modules, etc.
If you're using custom ROMs (including OOS based ones) or Open Betas you're on your own. I'm only interested on debugging stuff in stock and stable OOS.
Save the SOT and battery stats/screenshots for general threads, here we deal with development, not personal tastes and results.
Also don't spam this thread with CM or other ROMs stuff like "this don't work, my app doesn't open, etc" , no OT about OTAs, apps, ROM bugs, Recovery/TWRP troubleshoots and other userspace stuff. There's threads for it, use them.
Going back to stock: This kernel installer doesn't change your filesystem (systemless in case of Nougat). Oreo builds touch system partition.
You can backup your boot & system (Oreo) with TWRP before flashing blu_spark if you want to go back to full stock or just dirty flash your full ROM.
If you like my work, donations are always welcome.

wow i've read a lot of good things about your previous kernel. looking forward to trying this out on my recently rooted OP3.
Thanks!!
and as an aside, it's awesome to see how much development is already going for a phone that *just* came out. awesome!!
Would love to try but I need the stock kernel to switch back.

I've been around developing for other 2 or 3 devices
nevermind, i was reading the OP wrong, it says soon for blu-active gov.
I know it's not supported but for anyone on CM13 I gave it a go. On the A3000 I didn't have WiFi or 3g/4g. Just thought I'd let anyone considering testing it what I found.
thanks for the contribution brother

I am not responsible for bricked devices, dead SD cards, explosions, nuclear wars, alarm applications getting failed
The idea is to take the best from all available kernels like boeffla,blu_spark,franco kernel,elemental x,sultan,arter97,zanezam
to have a single kernel rich of features but at the same time stable and fast.
I will add only those features which don't cause instability and really improve performance or battery life of our device.
Thanks to all the kernel developers for many ideas, references and features, special thanks to andip71 for providing kernel source code ,I have used his kernel as base for my project

Awesome good to see. I'm going to ask the obvious question. Okay to use with nougat based lineage roms?
Gonna try this out and let you know how it goes! still using your unofficial AiCP rom! super smooth ?
Sent from my ONEPLUS A3000 using Tapatalk
Good Good! Another great developer! And especially when all the kernel developers do not support custom roms.
Looks very good. Can we also have gpu boost option like in elementalx kernel?
Thanks!
A question, does this kernel support sRGB mode?

Tried Kernal with Unofficial RR.
Mobile Data/WIFI doesn't work?
EDIT: Ignore me. Think its a ROM error not Kernel.
Good !!!
Flashing over Tesla !
Will you be releasing a config app for this or should we just use kernel aduitor?
Works on RR official by the way, I'll advise of any issues.
All the best with this kernel. Hope its unleashes the hidden potential from within the OP3 T
Does this include the Safetynet bypass to allow android pay to work?

EVERY rom has a kernel, what's your point? This is a custom kernel which will offer features that one doesn't.

It has a custom kernal already. So flashing another custom kernal on top just sees like a waste and asking for problems.
I know every rom has a kernal from LOS but not custom.
no luck on your AiCP rom. was stuck in a bootloop for a couple of hours. fell asleep with it stuck there and woke up this morning to it still there. I wiped cache and dalvik cache then flashed kernel
edit: so I read the OP and it says something about 4.0 firmware. I never upgraded my phone to 4.0 firmware, stayed on 3.5.3 then I rooted my phone and flashed ROMS, I never had a problem with your unofficial rom, or any other rom. I flashed the provided Recovery image you mentioned in your thread and flashed the ROM. is this why I'm bootlooping? cause I haven't upgraded to the 4.0 firmware?

So this isn't for stock 4.0.2?
Thanks for this either way mate

Back again!
You may remember me from my SkyDragon kernels for N6/M8/M7/G3 among other devices, I've been off XDA for a year or so, quietly making kernels and roms for myself and personal friends. Decided to come back to show the OP3 some love under my own moniker while the team is on hiatus.
This is the kernel I use as my daily driver, I'm not really looking to add things so if you want more, please find someone/thing else. My goal here to get as much performance out of our device(s) as possible without sacrificing any battery life or stability whatsoever. No Ofast or ffast-math flags that break IEEE and math operations. No beta toolchains. I compile my own toolchains from recent stable release, build them optimizing and targeting a specific processor instead of the whole architecture, and then I use those to build my kernels that are optimized for that same processor. So this kernel is meant to be as stable stock, all the performance, and none of the loss in battery. Anyways, on with the show..
~*~*Information*~*~
Kernel supports all OP3/OP3T devices running OOS Stable 5.0.x or OpenBeta 32-3x(OP3) and 23-2x(OP3T):good:
Kernel source is based on official OnePlus 3/3T openbeta source code :good:
Kernel has been compiled targeting msm8996 specifically :good:
All but C++, AR, objdump compiled with my custom-built Linaro 6.4.1 toolchain with LTO targeting msm8996/SD820/SD821 :good:
C++, AR, objdump from Qualcomm SnapDragon LLVM v6.0.2 targeting kryo :good:
Using ld.lld from clang 7 for linker :good:
No user setup required - optimal settings already applied :good:
~*~*Features*~*~
No user clock-speed modifications
Flar2 sleep/wakegesture features (Disabled by default, no vibration, enable with EX App)
Stock wake gestures still have vibrate functionality
Swappiness set to zero by default (we have plenty of ram)
vfs_cache_pressure set to zero by default (we have plenty of ram)
ZRAM disabled (why write to slow storage when we have all the ram)
Maple IO Scheduler set to default (IMO best balance of performance/battery life)
Westwood TCP Congestion Profile set to default (Personal preference)
CRC Check Toggle-able (disabled by default)(~%30 performance boost when disabled)
FSYNC Toggle-able
Boeffla's LED Notification
Boeffla's Wakelock Blocker
Savoca's KCAL Control
Fast Charge support for PC charging (1amp instead of .5amp)
Tweaked Alucard Governor (not default, will need to set manually)
DTS Eagle+DTS Ultra
KLapse-Livedisplay Support

NOTE:
Kernel zip tries to disable DM-Verity and forced encryption, you may need root however in order to boot.
Install if on something else: If in doubt, download this, flash latest openbeta zip from OnePlus, immediately reboot back into twrp, swipe to allow modifications, install this kernel, install magisk/supersu, profit.
If you're already on this: you can just flash my latest kernel zip and profit.

HDK-Mod - v1.0.0
This is my own modified build of Grarak's Kernel Adiutor app. Now unified for all my kernels.
I have added a few extras that were missing for sound control, pdesire audio, DCI_P3 mode, tbalden's kcal modificaiton, sultan's battery cycle/charge commit for msm8996, and Tanish2k09's KLapse-Livedisplay.
You may need to disable Play Protect temporarily to install, working on adding to the play store to negate this issue.
Also changed the theme, and updated some stuff.
Work in progress but needed something to fully control my kernel.
Full credits and much love to Grarak for putting in all the hard work on KernelAdiutor, wouldn't be here without his work.
My source for it is here.
This is an OOS Kernel yes? Or is it for Custom ROMs that are not based on OOS too?

May need dm-verity disabled/rooted if you're not already.
Finally posted something.. :good: Ran this for months before I sold my OP3 rock solid no bullsh!t. Good luck with the release!
Thanks ! I'll give a try just for the badass name

Now I understand why my device was soft bricked ?
Fortunately a dirty flash of my firmware was enough, no data loss.
I'll try the new one !
---------- Post added at 12:56 AM ---------- Previous post was at 12:42 AM ----------
Okay so :
- I flashed the 3.7 version and got stuck to OnePlus logo with "Powered by Android"
- I dirty flashed my ROM (BETA 29) and flashed the Kernel immediately after without rebooting and next I flashed Magisk 15 --> It booted
I'll see how the kernel run now.
Looking forward to trying this out! The name alone is pretty cool!
Hi, thank you for your effort for the kernel
Wanna ask, which apps I need to configure the kernel? Kernel Adiutor or EXKM?
Can It work on the H2OS?
Loved your work on my good 'ol M8, so I'm pretty excited to see you here. Thanks (as) always for the work!
Great to see a new kernel! Didn't see any mention about encryption or dm-verity. Does it bypass encryption and dm-verity?
Thanks
Excellent kernel it seems like solves the unbelievable, not compatible with Oreo's mobile phone game Caton problem.
By the way, what will happen if I use it on 7.1.1
Thanks a lot for the new Kernel, dude!
But, I would request you to add flar2 gestures, because in SA Region, it's kinda uneasy to use fp in winter!
came from a custom kernel on an encrypted 3T with magisk 15.2. managed to install this by first restoring stock versions of my system (system.img as opposed to just system) & boot (flashing Xennet's boot images w/ disabled dm-verity also works) backups. booted once to check everything's fine then back to recovery to flash the kernel. didn't need to reflash magisk as the system i restored from was already rooted. HTH someone who wanna try this kernel
thanks for your work, OP. will test & revert
Flashed on beta 19 but it broke wifi, i was on stock kernel before that. Any thoughts?

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
Designed for maximum stability
All the Source Code is available on github
Kernel Info
LINUX: 3.18.131
SAFETYNET: Green (Root will still break SN)
TOOLCHAIN: Google's GCC 4.9
Compatible ROMS
All Touchwiz 8.0 ROMs
Features
Here are the major features of the kernel (feel free to explore Github)
Up to date with the latest stable Linux version
Full -Ofast build with graphite optimisations
Removed a lot of useless debug and logging options
Disabled TIMA, KNOX, DM-VERITY,etc
Awesome battery life and smooth performance
ARM enhanced performance patches
Overclock CPU up-to 1.7GHz and GPU up-to 1146MHz
GPU Voltage Control
CPU Governors: conservative, interactive, ondemand, performance, powersave, userspace (default: interactive)
I/O Schedulers: bfq, cfq, deadline, maple, noop (default: maple)
Powersuspend and State Notifier drivers
Dynamic FSync, FS fsync toggle on/off
Frandom driver for 10-50x faster random number generation
Spectrum Support (a simple, profile based kernel manager || now integrated into Oxygen Control)
Disabled CRCs by default for 30% performance boost
CDROM emulation on mass_storage (compatible with DriveDroid)
Wireguard support
Boeffla Wakelock Blocker
Oxygen Control App Features
Full CPU and GPU Control
Boeffla Wakelock Blocker
Spectrum Support
Samsung Hotplug
CRC Control
And many more!

Download Oxygen Control from Github Releases
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.
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

Thanks , i used this kernel on my j7p and i missed it so much in J6, thanks
would love to see it has arm64_32binders or native arm64 kernel, with that we can use native GSI roms build for arm32 or arm64

This one has 64bit binder. I can make a separate build for GSIs with 32bit binders but i nees some tester for that. Anyone interested then PM
Works on J600GDXU3ARK5 ?
Have u already tried it ? If so can u put screenshot of the kernel control app thanks.

DOWNLOAD KERNEL ZIP
FKM download configs: HERE
(No mirrors please)
Setup and troubleshoot: To install just flash the zip on a stock setup with either TWRP or autoflash kernel app.
If you come from other kernel or have any issues, you should restore your stock boot.img or dirty flash your ROM before flashing blu_spark zip to avoid problems. Also uninstall or clean data of any kernel control app you're using.
If you are upgrading between blu_spark versions, just flash the kernel zip.
About bugs and reports: don't bother to post if a log isn't ready or without steps so the behavior can be replicated. I only active support stock ROM with NO mods whatsoever (apart from root). That includes NO support if using xposed, Magisk with added modules, etc.
If you're using custom ROMs (including stock based ones) you're much on your own. I'm mostly interested on debugging stuff in stock and stable ROM.
Also try not to spam the thread with OT. There's threads for all kind of stuff, use them.
Going back to stock: This kernel installer doesn't change your filesystem. You can backup your boot.img with TWRP or kernel app before flashing blu_spark if you want to go back to full stock or just dirty flash your full ROM.

Thank you for the support over the years mate.
I'm deeply grateful for all the good vibes since the early days on the N4 and the specially the fun we had on the N5. What a beast of a device.
Let's see how the Pixel run goes :highfive:
So far so good. Battery life seems to be on pace for 9hr SOT and that's even with AOD enabled which I never do just to squeeze every bit of battery life. Guess I'll report back sometime tomorrow to see how the first run goes. I know kernels usually take a few days before you can really get a benchmark. Been using your stuff since I developed on hammerhead all the way to OP6T. Missed how smooth and simple this kernel is.
First charge cycle. Very impressive, my friend. View attachment 5125905

Could I install this without TWRP? I wish to stick to full stock without having TWRP on (and cause the current TWRP build is not for 11 yet).

how do I verify that I successfully flashed the kernal and my device is using it?
how can I tell if I successfully flashed the custom kernel and my phone is actually using it? When I go under about phone this is all I see and it doesn't look like that I am on it. Can anyone help me confirm
