Development has stopped - see my last post HERE.
Introduction
Hello everyone, this is my personal kernel for the OnePlus 9 Pro.
My philosophy on the kernel is pretty simple, intended to replace the stock kernel, but with a lot of under-the-hood tweaks.
Hopefully you will all enjoy!
Important thread information!
I refuse to acknowledge/respond to bug reports that do not include clear steps to reproduce, a logcat, and a console ramoops (if random rebooting) or a dmesg (any other issues). Follow this guide to do this.
Keep things civil, no flaming in the forums!
Features
Up to date with OxygenOS 11 source
Compiled with Google's Clang toolchain for maximum stability, with all warnings and errors fixed
Compiled with Clang's cortex-a55 optimizations
Many tweaks under the hood for smoother UX, lower battery drain, etc.
Westwood as the default congestion algorithm (BBR is also available)
Available to flash with AnyKernel3
Latest kernel release on GitHub

Hi! Thanks for your contribution and kicking off custom development of the 9 pro!
I am very much new to the OnePlus device platform and I have no clue how to install this. Can you please provide some steps or guide as to how can I install this ?

Once you are bootloader unlocked and rooted on your 9 Pro, the easiest way to install is to flash the zip through a kernel manager, such as exkm/franco kernel manager. Take a backup of your stock boot.img as well.
Once flashed, reboot, profit!
Running 11.2.4.4 with Omega on my 9 Pro
Thanks Kristof!
Awesomely Smooth experience.... as usual.
Thanks Kristof!

Not want to be rude or anything but just use search. You can do those back ups easilly. And please dont do things that can potentially brick your device. No pun intended. Read read read. You cant never be too smart. Sorry about the rant
Flashed, running smooth all day. Thanks for sharing your work.
And it will not work for the regular 9? for the 8 and 8pro they were unified

I think he will work on it (maybe after kitkat is totally completed)
Nice to see that HTC One V is not dead! Great job mate!
Amazing work on this! I never thought my One V would even run KitKat, honestly.
Anyone notice a speed difference with and without Gapps? The ROM seems to be excruciatingly slow if I use Gapps, but if I don't, it's as fast as CM11.
Can you?
Can anyone tell me whole installation process please. Do i need latest recovery? How to install latest recovery through mobile?

Introduction
Buying Mi 5 gave me opportunity to spread wings and maintain a (hopefully) better version of Linux kernel for this device.
The idea is to provide two levels of modification, one - the most up-to-date kernel upstreamed with official Linux changes (also Android) repo to provide bug-free and stable experience, second - tweaks and additional features placed in top of upstreamed version to give blazing efficiency and battery friendly experience.
I came with the idea while looking onto linux repo - there are so many fixes and optimizations done to the code which gonna never come up to any Android device. So why not to try and pick some of these changes?
Android device is one of many for which Linux kernel is developed. Adding hardware specific changes will give extra performance and battery backup as it's going to use the phone architecture better instead of generic implementation.

Compatibility
It is LOS forked repo so any LOS-based ROM should be compatible (not MIUI compatible).
Do not use it with any custom ROM or additional modifications as I'm not supporting them (and will not).
Of course, you can try flashing, if it works - enjoy.
Downloads
You can use 'Download' tab in the top or download from AFH .
Installation:
- download kernel zip and necessarily check MD5!
- boot into recovery
- flash the zip (always flash on clean ROM!!)
- (optionally you can wipe cache/dalvik)
- reboot to the system and taste the madnesss

Before you exit:
Don't get dishearten because of 'poor' features list. Main advantage of this kernel is upstream of many parts. Changes in Soda are chosen wisely, I implement thinks that are supposed to benefit. You don't need XYZ, you need Soda
Known issues:
Upstream:
None
Soda:
- Battery idle drain (investigation in progress)
- Speaker gain is broken
FAQ:
Could you add XYZ feature?
I will not add features I personally think are useless or unneeded. I can only promise I'll take it into consideration. If you're so single-minded about that just fork repo and pull request - I'll pick it gladly.
Could you upstream XYZ?
Ok, upstreaming is nice unless you fall into conflicts or totally new code structure. Don't expect me to update the kernel up to 4.13, haha! I'll keep in mind what you're asking me for, but if you're so desperate about this I'm waiting for pull request .
Why should I choose yours upstreamed version?
Don't expect it to change your Mi 5 into S7 edge =)
Think about like that - some time ago Google forked Linux kernel at version 3.18.31 and added their changes, then Qualcomm forked it and added their changes, then Xiaomi forked and added their changes. There are a lot of bugs, memory leaks and other bad stuff in here and probably nobody will take care about it... Oooch, except me! My aim is to keep the code as most up-to-date as possible - so without rewriting a half of proprietary drivers.
Does it make any sense?
In my opinion - yes.
Our phone will be more stable, not vulnerable to newest 0-days and hopefully a bit faster and battery friendlier. The key is bug-free optimized code; magical tweaks do not always take the first place in making a kernel better. As of my experience using upstreamed version gives more battery and smoothness!
"My phone freezees help meeee!!!!!!!11oneoneone..."
Description, logcat, kmesg or GTFO.
Could your changes damage my device?
I don't take any responsibility for broken devices, firing from work or nuclear wars. It's a hobby project maintained in my free time. I carefully pick up changes not to mess up anything and add features that are checked and provided to work correctly. There is a small range of cases when you can loose your phone completely, typically it will just freeze and reboot.
Where is version for MIUI and EAS?
MIUI won't be supported because Xiaomi haven't updated their repo for a long time. Building for MIUI would bring more problems than advantages.
EAS is in testing stage and will be released soon.
Remember to hit like button if you like my work as it motivates me a lot!
Play with it and post your experience please
Firmware:
Now I'm also providing updated firmware flashables.
You can easily download firmware packages from AFH .
Happy flashing!

How to tweak my kernel:
1. Charge control:
Path of all tunables is
Code:
/sys/kernel/fast_charge
You have 3 tunables as follows:
maximum_qc_current (DEFAULT: 2800) - it's very important one, its value controls QC3.0 charging current. Recently there are commons problems with screens and the assumption is that too high current causes that problem. Lowering the value would also make your battery's life longer!
force_fast_charge (DEFAULT: 0) - it's common known knob to force 900mA charging on unknown sources. I tweaked it a bit and now, if it's possible, driver will choose higher values depending on the source.
charge_limit (DEFAULT: 100) - it's very interesting one, its value controls maximum percentage of which your battery will be charged. After given limit charging will be stopped. Lowering this value could benefit in prolonged battery life as capacity wouldn't decrease that fast. Scientific researches recommend charging your battery to 80%.
3.Sound control:
You can tweak it using Kernel Adiutor.
4.Sched features:
I would like to resolve doubts connected with Arch Power. On kernel v3.18 there isn't such a feature. Cherry-picking old interface doesn't change anything in fair scheduler, the only thing you see is magic switch which does... nothing. Our kernel has feature named Arch Capacity which is *let's say* correspondent to previous one so I created two tunables - arch_capacity and arch_power. These are mirrored values so now you can enable/disable it in KA as known Arch Power but please remember that you're changing arch_capacity in fact.
My recommendation is to disable Gentle Fair Sleepers because you can save battery a bit.
You can also tweak it using Kernel Adiutor.
miui support please...
Aosp support ?
Did you add somes cpu governor ? And for you which its the best to have a better battery
Envoyé de mon MI 5 en utilisant Tapatalk
Aleluya! Not much kernel variety on our mi 5, pretty thanks I will test it early dev
cheers
Download link (I've found it, but it would be better in the description)? Governors? SOT?
Great news Sir,
I hope soon we could have good costum kernel with great stability and compability with newer rom.
I wish you could support AOSP based rom too

I just started Soda developing so you have to wait sometime for custom tweaks.
According to governors I think the most important thing is to configure it nicely, sth like AKT or GovTuner does. Stock interactive is good.

AFAIK AOSP is based on LOS sources, it should work correctly
But some time it doesn't work properly on AOSP based rom, I used DragonXia as default kernel on every rom I flashed, but lately with latest release rom it's doesn't stable.
I hope you could made manually setting on/off the CPU core for better battery life, as hotplugging not save much battery life.
Overclocking was great too
I will test yours beta kernel right now Sir
CPU 0 and CPU 1 are stuck at 1593MHz.
Edit:
It seems like a restart solved it.
Edit2:
setting io scheduler to noop causes freeze.

Yes it's working now. The test-iosched scheduler caused the problem.
will you add miui 9 support? miui lack of custom kernel support. thanks for dev gemini kernel.
which features does it have? quick charge? eas ?
"disabled CPU Boost" this is real great, i guess you know what i want. waitinng for a more stable realese and then give it a try
I pushed a first beta of Soda kernel. I added a few useful features, but battery usage reduction should be significant. Try it on your own
Thanks for your work! I will try and report back when possible.

There are two branches:
Stable - which has all proven and tested development
Beta - new features introductions. Remember if your chip fries... It was done with good intentions, intended only for brave people.
To build this kernel I give a huge thank you to great dev @savoca has had a lot of patience and shared his knowledge to build a kernel with a step by step guide, as also explaining how each stuff works.
@andi79 for the introduction of the 64bit model kernel compilation.
All credits go to the OnePlus team.
Disclaimer: With the use of this kernel I am not responsible for any damage to the phone. It is at your own risk in case happens something wrong. I use this kernel daily and test it before release.

Battery drain:
This rom has a bug in the wifi. Please go to advanced settings and turn off scanning always available.
On status appears kernel 4.4.21
Since there is a requirement to the kernel say that is version 4.4.21-perf+ for wifi to work then I named the kernel 4.4.21-perf+. This until I check wifi driver source.

Yes, of course. Currently running the oc version with pixel dust GSI.
Btw this kernel is for android 9.0.
Feels good to see Nokia Dev community getting started.
Does this root method work on stock pie, December patch, even without flashing the kernel?
And also do you have gapps on your gsi? If so, how did you flash them? I was trying to install aex gsi, but it's a bit unstable and also no gapps

Yes. For Gsi you need to resize system partition after installing it, so you can install gapps.
Or just flash pixeldust gsi.

New build 0.6 rebased on caf is up. Gpu oc for now is not stable for our phone, i ve tryed. I will include it when it will be stable.
1.3 relase update:
-removed sound control (will re-add it when i have time)
-re enabled Bcl (for better battery backup)
-upstreamed to LA.UM.7.2.r1-06500-sdm660.0

Not for now kernel side. I ve removed Mic gain and Headphone gain for now. I will re add it later (had some problem with mic, but it wasn't the commits). Install ainur audio from Magisk if you want better audio (installation takes time).
Who want to test -80mv Gpu Uv can flash this:

/* Details */
- Fully rebased kernel without unnecessary OnePlus' code -
This kernel is not based on stock OxygenOS kernel source provided by OnePlus. Instead, it’s based on the latest and greatest Qualcomm has to offer. Only the necessary parts from the OnePlus kernel has been cherry-picked, such as OnePlus 7 specific device drivers.
This brings 2 major changes: less debugging code and an overall lighter kernel.
There are miscellaneous changes made by OnePlus that are supposed to maximize utilization of system memory. But seeing how it’s implemented(heavily relying on zram and a physical writeback swapfile), I decided to remove it entirely.
Users are recommended to disable the “RAM Boost” feature from Settings > System > RAM Boost.
Due to the completely different base, the memory management with this kernel will be drastically different from other kernels.
- Latest CAF msm-4.14 kernel fully merged -
This kernel is also constantly merging the latest Qualcomm Android 4.14 kernel. This tag contains more up-to-date changes from Qualcomm than the regular Snapdragon 855 tag(sm8150).
- Use CONFIG_HZ = 300 -
This changes the context switching interval from 10ms to 3.33ms. Pixel used this for years and Google recommends other vendors to do the same for less jitter.
This is even more important on displays with higher refresh rates.
- Optimized power configuration -
Stock OnePlus configuration forces display-related processes to use the Gold cluster(formerly known as big cores) exclusively.
This configuration brings a huge power regression since it makes every frame dispatch to wake up and use Gold cores.
This kernel resets this profile to use the configuration Google recommends, which is to use the Silver cluster(formerly known as LITTLE cores) exclusively instead. No performance penalty was noticed with this change while massively improving battery life.
- BBR as the default TCP network congestion control -
BBR is a (relatively)new TCP congestion control developed by Google, and it’s regarded as one of the best things you could do to your network configuration. You can find its benefits easily just by Googling BBR. I’ve been personally running BBR for months on various Linux machines including the server running arter97.com and it’s been great.
Now that our Android kernel is running v4.14, I’ve enabled BBR and backported other BBR changes from mainline.
/* Notice */
5G variant is unsupported.
Only OxygenOS is supported, but it is likely that the kernel will work with other ROMs. Though you may encounter minor issues.
Feel free to tip me which commits are needed to fix other ROMs.
/* f2fs */
OnePlus 7T and OnePlus 7T Pro users cannot use f2fs without involving heavy and risky repartitioning operations due to Dynamic Partitions.
r61+ allows using f2fs on OnePlus 7T and OnePlus 7T Pro.
This kernel fully supports f2fs for /data and I encourage everyone to use f2fs with my kernel for better performance.
See here as to why you might want f2fs.
The process differs with T and non-T series.
/* T variants */
The kernel now detects whether the userdata is in f2fs format and patches fstab on boot for OnePlus 7T and 7T Pro users during boot.
This is done in a volatile manner, which means your system files are not modified and using other kernels will revert the effect.
This is half of the puzzle.
The other half of the puzzle is to getting userdata partition into the f2fs format.
Due to lack of a proper recovery for the OnePlus 7T, I patched up f2fs-tools to support formatting while the Android is up and running.
You can use Franco Kernel Manager's flasher to flash the live-formatter.
This obviously removes all data on the device.
Please make sure your data is fully backed-up.
f2fs live-formatter:
https://arter97.com/browse/f2fs/liveformat
Existing f2fs users won't be affected by any of these changes.
Note that the OnePlus 7T and 7T Pro's OxygenOS has an issue handling FBE(File-Based Encryption) with f2fs(which is presumably why they left it out while the OnePlus 7 Pro had it), and encryption will be disabled when you use my kernel's f2fs live-patching feature.
Without encryption, your entire data will be in danger if you lose your device.
Please use f2fs if you understand this trade-off.
(Non-T series users can safely use f2fs with encryption.)
f2fs installation steps:
1. Download and install my kernel.
2. Download and install f2fs live-formatter.
OxygenOS OTA steps:
1. Install OTA and DO NOT reboot.
2. Download and install my kernel using Franco Kernel Manager.
3. Reboot.
Re-format into ext4 steps:
1. Use stock recovery and perform a factory reset.
Re-format into f2fs steps:
1. Use stock recovery and perform a factory reset and turn the userdata back to ext4.
2. Reboot to Android.
3. Download and install f2fs live-formatter using Franco Kernel Manager.
/* Non-T variants */
TWRP is not integrated to the kernel.
Please use a TWRP installer to install TWRP on top of my kernel.
To use f2fs, simply format /data to f2fs with TWRP.
Afterwards, flash f2fs-optimize.zip from http://arter97.com/browse/f2fs/optimize
There’s no need to flash separate zip files for replacing f2fs-tools or fstab.

I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this kernel
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you. Hard. A lot.

1. Read the above. Please.
2. Flash the zip file from your existing TWRP recovery.
2.1. FK Kernel Manager also works for installation. EXKM is unsupported and reported to brick the device due to installation failures.

I'll be the first. Just formatted my device and rooted it, first kernel im going to test!
Wow, very interesting changelog, will be interesting to see how it performs and what others think!
Conflicting decisions between kernel devs it seems on some features, like ZRAM for example.
Looking forward to flashing
Looking forward to flash, there's no klapse support right?
Edit: Damn this kernel is snappy AF ?
Congrats on this release!
Finally arrived! waiting for it since I know you are about to build one for op7pro.

/* Notice */
Both OnePlus 7 and 7 Pro is supported.
Only OxygenOS is supported, but it is likely that the kernel will work with other ROMs. Though you may encounter minor issues.
Feel free to tip me which commits are needed to fix other ROMs.
Android Q beta is not supported and I’ll not spend my time adding support for it.
Do not ask for premature Android Q beta support.
