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

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: 3.18.138
SAFETYNET: Green
SELINUX: Permissive
TOOLCHAIN: Google's GCC 4.9
Compatible ROMS
All AOSP 8.1 and 9 ROMs
All OneUI Pie based ROMs
All Touchwiz 8.0 and 8.1 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!
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.
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

In this kernel, I strive for balance battery / performance, as well as it contains the latest patches for Linux and CAF.
Kernel i make for AOSP Q with Q blobs. How each version on MIUI Q works, i don't know and me it not interesting (if you want use this kernel, you always can flash and test, pls don't report what something don't work on MIUI).
Features:
Base on last sdm845 Q CAF tag
Merge Google Common 4.9-q
Upstream last linux version
Compiled with Proton Clang and Full LTO, LLD links, Shadow Call Stack (SCS) and RELR enabled.
Enable support for NTFS r/w, sdFAT filesystem, F2FS and Implement rapid GC
Kcal Advances Color Control
Enable TTL target
Sound Control by flar2
Add Wireguard Driver
Enable support Sony Dualshock PS3/PS4 and Xbox Controller
Disable unused drivers
Scheduler/schedutile improved (WALT)
SchedTune Assist and CPUSet Assist
Enable select TCP algorithm, westwood by default
Network Signal Guru app compatible.
Simple LMK
Optimize for Android Q
Many tweaks/optimize for battery/performance
AnyKernel3 flashable zip by osm0sis
Installation:
Flash in TWRP recovery, then re-flash Magisk.
If another custom kernel (or my old version, up to 4.2 inclusive) is already installed, then you need to flash stock boot.img first, then magisk and my kernel.
Tuning apps:

it remains only to wait when xiaomi will lay out source code for pie,i think only with the release of stable version
I'm on xiaomi.eu 8.8.3, as expected, a couple minutes after installing the kernel, phone rebooted by itself. I have disabled fsync since then and it's been working for a couple of hours now without reboots. I will update tomorrow if it reboots through the night.

isn´t fsync supposed to be always on? I remember disablling it on my nexus 5 always caused random reboots.
Can I ask if it works on XE model with MIUI 10 global when Magisk installed?
I recall if I did so with stock kernel (BL unlocked), I ended up with bootloop.
I can have a try as it doesn't take me too much time but I would say if any one could give me an answer that would be appreciated.

It didn't reboot through the whole night. I will try turning fsync back on to check if it will start crashing again.
EDIT: After turning fsync on the phone rebooted itself after ~5 minutes, I then turned fsync back off and it's been 3 hours without a reboot.

Fsync prevents from data loss on system crash as far as I know.

Ok, tnx for help. I do not know why yet. Still test and then add to the first post this info.
Maybe they are logs turned off / on. Because I disabled many debug logs at kernel level.

fast charge (qc3.0) implemented by xiaomi, replace with another driver or remove restrictions, i will not.
Thanks for your work, I tried a little but after some hours try to changing governors with elemental x I had reboots and system isn't stable, so I revert to stock kernel trough dirty flash, I'm on miui Pro 8.8.2.
it seems that mipa can work on dotos，thanks for your work.

Confirmed working.
If on stock kernel with SuperSU, just flash everything back to stock, then this kernel and then Magisk. Everything works.
@palaych
Thanks for this great kernel running on xiaomi.eu 8.8.3 :good: - for me it seems reboots occure due to zRAM...system was laggy and stuttered while scrolling. Deactivated zRAM via EXKM (fsync switched back on) and it seems to run smooth w/o reboots until now.

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
CRC control
Frandom
UKSM (Ultra kernel samepage merging)
ARCH power
USB charging default changed to 900mA
CPU and GPU voltage control
DevFreq voltage control
CPU overclock to 2002 Mhz
GPU overclock to 1034 Mhz
Configurable wakelocks
Boeffla wakelock blocker

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.

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)

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
Simon
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.

How often will you update this kernel?
I won't release updates often, but i will still update source and
you are free to compile it yourself.
/*
* .NOTE:
* .If you plan to do so, don't contact me for help
*/
Is my ROM/device supported?
As long as it is OnePlus 8T or OnePlus 9R, and as long as your rom is based
on Android 12, then yes, it is supported.
/*
* .NOTE:
* .OnePlus 9R has not been tested, so I do not guarantee its full support.
* .The same thing goes for Android 11 ROMs (including AOSP one(s))
* .as i did test only on Android 12 AOSP ROM.
*/
Which toolchain did you use?
• Compiled with latest cutting-edge LLVM-Tools-14 (https://llvm.org/docs/ReleaseNotes.html), with LLVM_IAS (integrated assembler), with Clang compiler (refer to https://clang.llvm.org/) and with LD.LLD linker (LLVM linker, refer to https://lld.llvm.org/) to have increased performances and smaller zImage (aka kernel Image) size (which is around ~50MB, compared to the over ~100MB Image of other kernels.).
Toolchain link: https://github.com/ClangBuiltLinux/tc-build
Features
• Compiled with Full LTO (Link Time Optimization, https://llvm.org/docs/LinkTimeOptimization.html), which makes kernel Image bigger than with ThinLTO but also increase performances by a lot (https://docs.google.com/spreadsheets/u/0/d/1mhjyshujZz8jYI7dMoCe-yFbxymW-fWaC08vMhBbEmQ/htmlview).
• Compiled with CFI Clang (https://clang.llvm.org/docs/ControlFlowIntegrity.html) and with Shadow Call Stack (SCS, https://clang.llvm.org/docs/ShadowCallStack.html) to improve security by a lot, but with a little less performance and a little more overhead (around ~1% of overhead, https://source.android.com/devices/tech/debug/shadow-call-stack).
• Disabled STune (SchedTune) in favor or UClamp (UtilClamp) to achieve less jank (jitter) and less fps drops (refer to https://www.linuxplumbersconf.org/e...hments/328/552/UtilClamp_usage_on_Android.pdf).
• Disabled WALT in favor of PELT, even if benchmarks clearly say that WALT is better, i did not see any lag or latency issue (refer to https://www.slideshare.net/linaroorg/walt-vs-pelt-redux-sfo17307.
• Upstreamed F2FS (/data filesystem) to latest (5.16) available mainline port for linux 4.19 (https://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs-stable.git/tag/?h=5.16-rc1-4.19).
• Upstreamed EXT4 (/system, /vendor, /odm, /product filesystem) to latest commits found in linux mainline.
• Use EAS (Energy Aware Scheduler) along with Schedutil governor to improve battery backup and keep high performances.
• Improved cfq I/O scheduler to reduce jitter by a lot.
• Disabled some debugging and tracing features such as Coresight (https://developer.arm.com/ip-products/system-ip/coresight-debug-and-trace).
• Disabled most debugging functions treewide to achieve less overhead and a smoother experience (as debug prints logs in dmesg, there may ve high I/O Disk usage, leading to a notable performance lose): Android binder, mm, drivers, ion, techpack drivers...
• Built qcacld-3.0 (network driver) and most techpack drivers as user and disable useless debug.
• Compiled with LLVM-Polly up-to-date flags to tweak LLVM-Tools and so to get smaller Image and better performances (refer to https://polly.llvm.org/ and to https://polly.llvm.org/performance.html).
• Tweaked UDFPS (Under Display FingerPrint Scanner, aka FOD, Fingerprint On Display) to faster unlock experience (https://github.com/FraSharp/kernel_oneplus_sm8250/commit/6fbf5a20fc78f954818649eb9048a63077bc0f0f).
• Disabled many unused configs to reduce kernel Image.
• Compiled some kernel parts with -Ofast to increase performance on critical points, such as fingerprint and display (https://www.phoronix.com/scan.php?page=article&item=gcc_47_optimizations&num=2).
• Upstreamed kernel to latest ACK (Android Common Kernel, https://android.googlesource.com/kernel/common/+/refs/heads/android-mainline) tag and to latest CAF (Code Aurora Forum, https://source.codeaurora.org/quic/la/kernel/msm-4.19) tag to address latest CVE and to improve kernel treewide.
• Built vdso32 to get better battery backup and better performances according to Google (refer to https://source.android.com/devices/architecture/kernel/config#vdso32-on-arm64)
• Fixed PD (Power Delivery) charging, you can now charge phone with your laptop now at a reasonably good speed (~1400 mAh, tested with OnePlus warp cable and MacBook Air).
• Disabled pstore (logging and debugging feature) as it doesn't work.
• WireGuard VPN tunnel support and upstreamed to latest commits from mainline (https://www.wireguard.com/).
• Upstreamed ZSTD and LZ4 compression algorithms to latest commits from mainline.
• Tweak scheduler to achieve less overhead and better latency (lower).
• Added USB-2.0 fast charge upto ~900mAh (https://github.com/FraSharp/kernel_oneplus_sm8250/commit/1669d653a321f8a491df02b42f5a472fa177db9e).
• Added better number generator, LRNG (Linux Random Number Generator) (https://www.chronox.de/lrng/doc/lrng.pdf).
Very cool, you put some random features, but how to install this?
First of all, make a backup!!! I don't want to be blamed if you lose your data.
1. Download kernel zip from the link in thread.
2. Now you have 2 ways to flash this:
.A) Use Franco Kernel Manager (https://play.google.com/store/apps/details?id=com.franco.kernel&hl=it&gl=US)
.Go to flasher and then press on "Manual Flasher" button, select kernel zip and press "flash and reboot".
.B) Use adb sideload from recovery: Press on apply update, adb sideload, and then execute this command within pc's terminal:
Spoiler: command
adb sideload <drag n drop kernel zip here>
.If you get "Signature verification failed", change recovery.
3. Flash dtbo with
Spoiler: command
fastboot flash dtbo dtbo.img
/*
* .NOTE:
* .This is an AnyKernel3 zip, so you won't need to
* .flash Magisk again if you have it installed.
*/

Note: Custom kernels are NOT supported unless the kernel says it supports PA and GMS is included!
this is a part of text found in https://forum.xda-developers.com/t/paranoid-android-ruby-beta-4-oneplus-8t.4206613/, it goes the same for aospa sapphire

it is a little more focused on performance than battery, but battery backup is very good
I really want to try this on Havoc but Havoc is still on android 11. I'm a bit scared, i might break my 8T

it should boot, at most you will have some casual bugs (most likely non working wifi, but it's very unusual to happen), anyway it won't damage for phone. in the worst case it won't boot and all you have to do is reboot to recovery and flash a working kernel

Ohhh i see thank you so much! I'll update if it works on Havoc Os

It booted on HavocOS 4.12, no problems found on a quick glance, however on a startup "there was an internal problem" notification popped up.
OP - you might want to include dtbo.img in kernel zip, as AnyKernel3 handles flashing dtbo too (it worked when I copied it), no problem with flashing using OrangeFox Recovery.

good about the no issues on android 11, the internal problem popup is there and we can do nothing about it , i didn't know that AnyKernel3 handled dtbo, so thank you for letting me know that, bye.

Hello OP, I'm going to try this on Havoc OS 4.12 (Android 11). If i'm going to flash using EX kernel manager or FKM. Do i still need to flash dtbo?

This booted on my 8pro without dtbo
