have you tried the HolyDragon kernel?
(or BluSpark or SmurfKernel?)
how does it compare?
One small bug, the link speed for wifi is always 0.
The wifi works fine though

If I'm on oos 9.0.5 with xXx and Renovation rom with stock kernel all I have to do is flash this kernel zip right? No need to flash the boot image?

Oh... Maybe this is exactly for stable oos? Idk... What version of magisk did you flashed?and what kind of error did you get? Bootloop or maybe Qualcomm crashdump? Or it is rebooting to recovery?
Kernel is pretty smooth but on the balanced profile the big core is at least 25%-30% on the top frequency just when browsing net or chatting WhatsApp. Normally smurf and holydragon doesn't act like this on balanced profile

DOWNLOAD KERNEL ZIP
FKM download configs: oos | custom
Extras download location
(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 OOS 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) and OOS Open Betas you're much on your own. I'm mostly interested on debugging stuff in stock and stable OOS.
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.
OnePlus 5 development unit donated by OnePlus. Big shouts to them
Very proud of being on the OnePlus Developer Program, special thanks to Adam K. for being such a supportive person.

blu_spark r8
All right crew!
First build of your favorite kernel is up. Wicked!
Just got an OP5 developer unit yesterday from Oneplus, so today you already have a fully featured blu_spark build.
Most of the features you are used to from blu_spark on OP3/3T and others are in, this first build was compiled with Linaro GCC 5.4 (blu_naro 7.1 build still need some work).
Pretty happy with the stable and smooth base, next weeks will bring more of the usual goodies, there's still lot's of room for improvements :fingers-crossed:
blu_spark_r8-oos_op5_49e4692.zip
First public build (check OP and github for details)
Click to expand...
Click to collapse
Keep it real, keep it true, keep it blu :highfive:
Keep in mind: I will give no active support for custom ROMs (including OOS based ones) or OB.
Meaning, if using anything besides stock and stable OOS don't bother posting about it.
I am only interested on debugging stuff in stock and stable OOS (with logs and reproducible steps to replicate the issue).
Don't spam this thread with CM or other ROMs stuff like "this don't work, my app doesn't open, etc" or debugging features.
Custom build isn't compatible with EAS stuff.
Also don't go spam and bug reporting on ROM threads if using this.
If you like my work, donations are always welcome.

Loved your kernel on my old Oneplus X and Nexus 5. So awesome to have you back.
Congrats for getting recognised by OnePlus and getting a free OP5. :good:

For the time being my priority is OOS kernel and will consume pretty much all of my time since it has lot's of new stuff.
Omg, my favorite kernel now on the OnePlus 5 :laugh::highfive:
Wow this was quick, considering you only got the device yesterday.
Keep it up buddy !!
Is this OK, or do I need to flash again? I download the zip from the first post, flash in twrp, the app comes with a update.

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: 3.18.132
SAFETYNET: Green
SELINUX: Permissive
TOOLCHAIN: Google's GCC 4.9
Compatible ROMS
All Touchwiz 8.0 and 8.1 ROMs
All AOSP 8.1 and 9 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

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. This is generally needed if you are installing this kernel on stock tw rom

ABOUT:
This is my personal kernel project, which I looked to be a stable kernel for daily usage, with useful features only, and to have a half term under performance and battery life for Xiaomi msm8996 devices. Inspired by projects like Flash Kernel and ElementalX Kernel
"While I am not a super star kernel developer, I do know my way around it." (Chancellor, Nathan - 2017)
PROJECT GOALS:
Keep kernel up-to-date with lastest stable Linux Kernel version (3.18.123)
Offer the user the best balance between battery life and performance
Just useful features. Features may be included only as needed (Read FAQ section to know the features that I won't add in anyway)
FEATURES:
Here are the major features of the kernel (More details on the Github repo)
Up-to-date with the latest stable Linux Kernel version (3.18.133)
Mainline Linux patches for CFQ
Several subsystems converted to use power efficient workqueues
Hides bootloader unlock from SafetyNet (can still fail through other means)
Available to flash with AnyKernel2 (thanks to @osm0sis)
Users facing features:
KCAL color control
USB Fastcharge
Adreno Idler
Boeffla Wakelock Blocker
INSTALLATION:
Boot to recovery
Flash kernel zip
Reboot
Yay! You've installed the kernel :victory:

F.A.Q:
Q: Are you Planning to support MIUI?
1. A: No.
Q: Could you include feature x,y and z in your kernel please?
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 won't promise that I will merge every request but I will always take it into consideration. I will NOT add:
Overclock or underclock of the CPU and GPU (Except for the cases that the device has a underclock on both or in just one, then it'll be considered)
Undervolt
Any other governors except the "kernel stock" ones
Any feature that just one or two people is going to use
Q: I'm having an issue, can you help me?
3. A: I'm 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. If I can't reproduce reliably, I'm not going to fix the issue. (Extracted from Nathan Chancellor's Flash Kernel Thread)
Q: The kernel is f*cking up my battery! Plz...
4. A: Stop right there. The Kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone. If verified the clocks are always online and on the max clock, then it'll checked out what's happen. Anyway logs are necessary.

Any other developer that I might forgot
ADDITIONAL NOTES:
ABOUT KERNEL USAGE IN OTHER ROMS THAT ARE NOT MINE:
You are free to use the kernel if you want. The only thing that I'll request to do it's to keep the kernel name. If you have modified something, just add a "-Mod" in the final of the kernel name or anything that states that the kernel has been modified, not by me, but by ROM maintainer.

Interesting! Finally a kernel that focuses on stability and battery life.
I'm hoping for some good releases, good work!
Is it a EAS or HMP kernel?

As stated on thread title, it's HMP. I'm planning to do an EAS version soon.
Does It work over Nougat? Thanks.

It's working on Pie ROMs as for now, but with the rebase of all stuff for Pie, the version for Pie and Oreo will be separated from one and other soon.

Flashed on ArrowsOS - HMP Pie. Stable, but some lagging not sure if ROM or Kernel or both combo not good. At least Touchboost and CPU boost helped.

Hello everyone, this is my personal kernel for the OnePlus 5. While I am not a super star kernel developer, I do know my way around it. Hopefully you enjoy :highfive:
NOTE: This list fluctuates with versions, it will not always been 100% up to date
Here are the major features of the kernel (feel free to explore Github)
Based on GzR kernel
Up to date with the latest stable Linux version (4.4.159)
Up to date with the latest CAF branch (kernel.lnx.4.4.r27-rel)
Mainline patches from Linux, focusing on bug fixes/security
Mainline CFQ scheduler improvements
Several subsystems converted to use power efficient workqueues
Backlight dimmer
KCAL color control
CPU Input Boost driver
Devfreq Boost driver
Sound control
Wakelock control
Westwood as the default TCP algorithm
Built with the latest Google Clang 7.0.2 toolchain
Hides bootloader unlock from SafetyNet (can still fail through other means)
Disables dm-verity
Does NOT modify decryption status
Flashed with AnyKernel2 (thanks to @osm0sis)
Primary: https://androidfilehost.com/?w=files&flid=283181
Through TWRP:
If you are on a custom ROM:
If you are on the kernel that came with your ROM: flash the kernel zip and reboot
If you are on a custom kernel: dirty flash your ROM zip, flash the kernel zip, and reboot
Upgrading from one Reaper version to the other:
Just flash the kernel zip and reboot
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, I'm not going to fix the issue.
1.2 Q: What ROMs are compatible with the custom builds?
1.2 A: My daily driver is GZOSP so I test all the builds on this ROM but this kernel should work on other pie ROMs. If you are using a ROM with no issues, let me know and I'll add it here! If you are having issues, following the above steps and I'll attempt to fix whatever incompatibility there is. If I can't do it without breaking GZOSP compatibility, you're out of luck.
1.3 Q: Can you add xyz feature?
1.3 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.
1.4 Q: How do I control the kernel?
1.4 A: I want to be very clear: the kernel does NOT need to be tuned to be useful. Most of the improvements are under the hood and don't require any user intervention to take advantage of them. In fact, if you don't know what you are doing, you could degrade the experience. To control the user visible features of the kernel listed above, I recommend using @flar2's EX Kernel Manager.
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.

Added to the OnePlus 5 Index Thread here. Also, a suggestion @FRNKSTN, do include the [KERNEL] tag in the thread title, because at the moment the title doesn't convey whether Reaper is a kernel or a custom ROM.

It's working good still. It should theoretically work fine with Oreo until OnePlus releases Pie or until there are too many Pie specific commits in the kernel.

DOWNLOAD KERNEL ZIP
Kernel Flasher/FKM download configs: oos | custom
(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/vendor_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 OOS 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) and OOS Open Betas you're much on your own. I'm mostly interested on debugging stuff in stock and stable OOS.
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/vendor_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.

Don't forget to hit thanks, it's free
OnePlus 9 Pro development unit donated by OnePlus. Big shouts to them
Very proud for being on the OnePlus Developer Program, special thanks to dev relations team.
blu_spark_r23 release
First blu_spark build for the OP9 series is up
This kernel is tested for the 9 Pro but it's unified, so should work for the OP9 also (need some fixes since code is broken). So backup you boot if you want to test and let me know
Kernel already have some merged goodies and I think I have a good base to work with. For a couple days of work, it's not bad
I'll take a look into more stuff to come, some things in OP are WIP. Stay tuned!
You can use FKM download kernel feature, just import the links bellow in the app.
FKM download configs: oos
Changelog:
Build with Google Clang 12.0.5 + LLD linker
Synchronize codes for OnePlus 9/Pro Oxygen 11.2.6.6.LE25AA
Several build error fixes and quirks handled
Compilation improvements an cruf removed
Some goodies already merged like filesystem stuff, cpu governor & boost/msm perf, TCP algos, wakelock blocker, vibration and haptic feedback control, gpu adrenoboost, etc
All drivers builtin, wifi stack and datarmmnet merged from CAF
net/wireguard: merge v1.0.20210424

Keep in mind: I will give no active support for custom ROMs (including OOS based ones).

Just flashed and going to test on stock settings for the next 2 days! Thanks for this I ran your kernel on the 7t pro!
@eng.stk I think the kernel has the same issue as Omega had, wireless charging seems to stop at 95%
Dumped out some logs if it will help
EDIT : OK, Apparently I'm talking crap, just seemed to be charging slowly but did get to 100%

If you need to revert to stock, extract and flash it from the OTA update in the pinned thread (follow LineageOS's instructions on how to do that), or just flash the magisk patched one in that pinned thread.
