[DISCONTINUED][KERNEL][G906S/K/L][4.4][5.0] Lolliwiz Kernel R10 [Sep 8]

This post can be updated anytime.
For korean support and for those who can translate Korean, visit my blog:
http://kykint.tistory.com/
Download TWRP Recovery v2.8.7.0 for G906SKL
/* Requirements */
* Galaxy S5 broadband LTE-A (SM-G906S, G906K, G906L)
* Samsung stock firmware or Dokdo-projct
- Kitkat: ANK1
- Lollipop: BOG2 for G906K, BOH1 for G906S/L
* Custom recovery (Philz, TWRP, etc)
/* Note before using */
* Backup important data before installing
* Upon installation, every warranty inclusing KNOX becomes void
* I, kykint, am not responsible for any inconvenience or problems that occur while using this kernel
* Only one hotplug driver should be on (mpdecision, intelli_plug, alucard_hotplug, lazyplug)
Lazyplug is currently not supported on kernel customizing applications. Wait until their developers update.
* Dokdo-Project version of lolliwiz is highly experimental. Don't complain about battery drain.
It also does not support uninstaller yet.
/* About new installer */
Since Release 9, the installer will automatically extract your device's ramdisk, merge it with lolliwiz kernel, and then install it.
Upon installation, if a backup folder (/system/lolliwiz-bak) is found, it will automatically restore it first and then continue installation.
It will backup original boot.img and sensors library to the backup folder (/system/lolliwiz-bak) while installing.
There might be some problems regarding this new installer, so please keep the following instructions in mind.
* When installing another variant's ROM, do not install lolliwiz right after flashing ROM.
Install the stock kernel of your variant, and then install lolliwiz.
* Those who have been using R8 or older version of lolliwiz must flash stock kernel first before installing R9 or later.
* Do not install stock kernel when lolliwiz is installed on your device.
Only install stock kernel when uninstaller fails to remove lolliwiz and restore to stock kernel.

LW-G906-Dokdo-R*.zip : for Dokdo-Project users
LW-G906-R*_F2FS.zip : for F2FS users
/* F2FS Conversion Manual */
Refer to the 2nd post.
/* Chatters */
Release 9 and 10 are mostly bug fix releases, so there isn't much difference.
Kitkat support has been put off to R11, and if a bug is found again and R11 happens to be released early, it will be put off to later release again.
Still, I'm considering EOL of kitkat version as it is becoming harder to support the old Linux version.
/* Contacts */
You can contact me through telegram @maplezeon, but I won't listen to complaints.
On weekdays I'm mostly at school, from 7am to 10pm, so there's no much time for chats.

F2FS Conversion manual
/* F2FS Conversion Manual */
(for LP and Dokdo-Project only, no KK support)
(Not tested on Dokdo-Project)
I will not add any additional explanations about F2FS, since this is a very risky task and recommended only for experts,
and since not knowing about F2FS means that you're not one of them.
Cautions
1. Conversion process of /data partition and filesystem will wipe away every single data in your device,
so every data in internal sdcard should be backed up on your PC.
2. Flashing /cache partition image when the device has already been converted to F2FS will format /cache partition to EXT4,
so manual conversion process of /cache partition to F2FS must be done again.
3. The /cache partition image mentioned above is included in stock firmware package, so be careful when installing stock firmware
4. Inside stock firmware is included a stock kernel which only supports EXT4, so again, be careful when installing stock firmware
5. /data and /cache partition must be set to the same filesystem, both EXT4, or both F2FS
6. I personally recommend that every process be done using my TWRP recovery, which will be posted in a seperate thread later.
7. The F2FS version of kernel zip has a '_F2FS' tag at the end of its filename, while EXT4 has nothing.
Be careful, Dokdo-Project version supports both EXT4 and F2FS, so they're not seperated,
and when converting to F2FS on Dokdo-Project, you can skip kernel switching(reinstalling) process.
How to change filesystem on TWRP
Wipe > Advanced Wipe > (Select a partition) > Repair or Change File System > Change FIle System > (choose between EXT4 and F2FS) > Swipe to Change
* It takes a great amount of time when changing to EXT4, up to several minutes.
How to check current filesystem on TWRP
Wipe > Advanced Wipe > (Select a partition) > Repair or Change File System
and you'll see your current filesystem on the upper part of the screen.
Converting to F2FS
0. For stability, flash uninstaller first if you already have lolliwiz installed.
1. Install F2FS version of Lolliwiz. (_F2FS.zip)
2. Change the filesystem of /data and /cache partition to F2FS.
3. Reboot into recovery mode again.
Back to EXT4
0. For stability, flash uninstaller first if you already have lolliwiz installed.
1. Install EXT4 version of Lolliwiz.
2. Change the filesystem of /data and /cache partition to EXT4.
3. Reboot into recovery mode again.
Installing stock firmware on F2FS
1. Reboot into download mode and install stock firmware with odin as usual.
2. When the installation finishes, it'll automatically reboot into recovery mode and flash CSC package.
Wait until androboy disappears and the device reboots again.
3. Reboot into download mode again.
4. Install my TWRP.
5. Reboot into recovery right after installing.
6. Install F2FS version of lolliwiz.
7. Format /cache partition to F2FS
8. Run factory reset if needed. This is an option.
9. Reboot.
If the device won't boot even if you carefully followed all of the above instructions, repeat the process again.

Thanks

Thanks I was on the Korean forums yesterday trying to translate lol.

I noticed there's a test for b5. Giving it a try.
One issue I seem to have on b4 and 5 test is that no matter what kernel tuning app I use if I turn off mpdecision and intelliplug on, after a reboot mpdecision always comes back on.

Kernel settings are set to defaults on each reboot and the default setting on hotplug is mpdecision on, intelli_plug off. That's why every kernel app has the ability to restore previous settings after reboot. Try enableing them, kernel adiutor works fine for me

Thanks, but I told it to save settings. It's weird as all the settings were saved, including intelliplug on, but mpdecision was turned on as well. I'll uninstall it and start again!

Nice to hear it's working well now.
I don't get donations, maybe you could donate to the REAL developers out there, they're always working hard for us XD

Very interesting!
I'm reading the Asian forums since a week and I have found that this kernel is well used.
How can I flash back stock kernel if something happens? And where can I find stock kernels??
If they are unavailable, I'd like to make my own Odin tar.md5 files for flashing stock kernel.
Can I follow the script/batch procedure (found here on Xda) that produces the tar.md5 flashable files?
Tnx!!

Good!
I'm following the Asian forum where I've found this kernel and related config app, from which I've read that there's a modified version of the app....And for this please give me some infos.
I'm also searching for some interesting custom rom as I see there are some, like the KingWolf one or the Milan one.
Any help on using this kernel with some roms?
Tnx!

I uploaded lollipop stock kernels for both recovery and odin. I'll upload for kitkat as well when I get the latest kitkat firmware.

Sorry, this might be a dumb question, but I'd rather ask it then brick my only smart-phone:
I'm currently on miscom's ROM (see here: http://forum.xda-developers.com/galaxy-s5/development/galaxy-s5-g906-custom-rom-t2848569)
Also using Philz recovery
How do I get to the Lolliwiz Kernel safely? Can I keep my apps, settings and so on?
Again, sorry. This is my first android phone (but certainly not the last one!) and I'm pretty clueless... But getting the miscom kernel on it was pretty easy with a bit of reading...

Make a backup of whole apps with TitaniumBackup first, then backup system, data, boot in philz recovery(run custom backup) and flash stock lollipop through odin. miscom's rom is 4.4.2 as I know of, and my kernel supports 5.0.1 only at the moment.
If your phone bootloops after flashing lollipop, factory reset through philz and restore apps from TitaniumBackup, or flash back stock kitkat firmware and then restore system, data, boot in recovery.
Note that flashing stock firmware will blow away your recovery and you should manually install it again with odin. Also, factory reset through philz will preserve your internal sdcard but stock recovery WILL NOT.

In plain language
DO NOT STEAL MY SH*T !!
UpInTheAir is NOT responsible, the person you see in the mirror is !!
REQUIREMENTS:
Supported variant only !!
Touch Wiz Android M 6.0.1 ROM or UX leaked firmware (beta support)
Appropriate custom recovery (i.e..TWRP for your variant)
INSTALLATION & UPDATE:
If you have Synapse installed = = you must clear Synapse app data before flash !!
Device Settings: Enable Developer Options > OEM UNLOCK is ENABLED
Boot into custom recovery (volume UP + home + power)
DO NOTHING but flash SkyHigh kernel.zip (ALWAYS flash again AFTER any custom ROM installation, system or data wipe)
After flash == DO NOTHING but REBOOT IMMEDIATELY from TWRP or you will have to re-flash !!
CONVERT EXT4 TO F2FS FS:
If not already, install the latest TWRP for your device variant (ie. 3.0.2-2). This must support F2FS.
Boot into TWRP.
Insert USB-OTG
** ALL DATA WILL BE WIPED FROM INTERNAL STORAGE (restored later)
Backup (copy) all important files (incl. your NANDROID) off device (ie. from internal storage > USB STORAGE). This can take a while. Advanced > File Manager > .....
Home > Backup > Select Storage > USB Storage > OK > "Swipe to Backup" (Only need DATA, but recommend to backup all partitions).
Install > Select Storage > USB Storage > OK.
Select f2fs.zip > "Swipe to confirm flash" (This will WIPE ALL DATA !! & convert DATA & CACHE to F2FS. System is not supported by kernel).
Check the box to remember setting and “Swipe to allow Modifications”.
If you do not have Step #8, then Data was not converted to F2FS.
Mounts > unchecked both Cache & Data. Repeat Step #7 & 8.
Restore > Select Storage > USB Storage > OK > Select TWRP Backup folder > DATA ONLY !! > "Swipe to Restore" (ignore warning about EXT4).
Home > Install > Select Skyhigh_kernel.zip > "Swipe to confirm Flash".
Home > Mount > USB STORAGE > uncheck/unmount (then remove USB-OTG).
Home > Reboot > SYSTEM.
Wait ~2-5 mins for boot.
Once booted, let stabilize for ~5 mins.
You can check Data & Cache F2FS FS status in either /proc/mounts or Synapse app (FS section).
Use a root type explorer (su permission) & navigate to /sdcard, and delete the "0" folder.
Move (copy) your backed up files from Step #4 to internal storage (/sdcard). This can take a while. Maybe one folder at a time is better?
ISSUES ?
If using TWRP MTP mode, deleting some folders/files may crash TWRP and cause corruption. Instead, use a root type file explorer to delete from device.
If you need to wipe data, then use the ext4 or f2fs.zip, otherwise this is not possible with this TWRP !!
Not tested any method with customized ROMs. The ROM installer script may re-format partitions back to EXT4 or not mount correctly causing TWRP crash or corruption. I can only suggest to Flash ROM with EXT4 FS > make a NANDROID on USB-OTG and then follow the F2FS steps above.
CONVERT F2FS TO EXT4 FS:
The Same steps as above, but use the ext4.zip !!
OPTIONAL SYNAPSE INSTALLATION:
After boot:
Wait at least 120 secs to stabilize
Install Synapse app from Google Play and rate it ☆☆☆☆☆ !!
Open Synapse
Tap "Understood"
So changes stick every time you start Synapse == Make any change & 'apply'.
Recommend: Disable KNOX with Synapse
DOWNLOADS:
** I will NEVER support KOREAN (S/K/L) variant. Get over it and flash ARTER kernel instead !! **
Mod Edit: Link removed.
BUGS:
Aroma Installer: 10% of installation will encounter Aroma installer "freeze". It's only the display that freeze, the script still execute in the background. Just wait a minute, then press slightly to the top right 'home' key / top left of the 'back' key . . .

FAQ & HELP
TROUBLESHOOTING GUIDE:
I might not have your device variant and or able to reproduce your "issue".
Please provide as much information as possible.
Without resetting your device to a stable unmodified baseline, any potential troubleshooting or logs could be meaningless.
So please follow the guidelines set out below. Users can't "read minds".
Without providing important information, we are unable to help YOU.
Search thread, XDA and Google before posting
Provide as much information as possible.
- Device model
- Firmware version
- ROM name / version
- Kernel version
- Modem version
- Bootloader version
- Synapse settings (try default)
- Installed tweaks and apps etc (Xposed ?)
- The exact steps you've taken to try resolve the issue yourself.​
Exact steps to reproduce the issue. Provide screenshots if able.
Does it work with older / other versions etc
Reset your device to a stable baseline (ie. stock) with only custom TWRP recovery and kernel (FULL WIPE: system, cache, dalvik-ART)
Possible logs
FAQ & HELP:
CAN I BUILD A KERNEL FOR YOUR __XX DEVICE ?
Sorry. I don't have the spare time for any more variant support.
Additionally, I do not build for any device that I can not compile using SAME source, personally test method or debug. Some device variants can compile with same source.
CAN I INCLUDE SkyHigh KERNEL IN MY ROM
NO == My ramdisk modifications are COPYRIGHT (refer LICENSE in Post #2), and distribution without MY (UpInTheAir) prior written consent is not only in a breach of that license, but also XDA Rule #12)
Although I do appreciate your contribution, if you could please do not include my kernel in any ROM package etc. This policy goes for anyone.
Having my kernel distributed outside my development thread just removes a lot of credit and more importantly, constructive user feedback that could be helpful to my development or user issue.
ALWAYS on DISPLAY (AoD)
I have spent some time to attempt port S7 display drivers to our kernel, but haven't had success as yet with too many errors.
TBH, it's a lot of work for something I'm not really interested in or would use. . . so I don't wish to spend any more of my own time on it, sorry. If someone else does it, GREAT
DO I "NEED" SYNAPSE
THERE IS NO "NEED" !!
It is "recommended", which is OPTIONAL, and not "needed".
It is for ADVANCED or adventurous users who wish more control of their device or use various features I've added.
Using any other optional tweaking or control app may conflict & many features and options won't be available.
WHY WAIT 120 SECS
The kernel and Synapse scripts need time to boot up properly and allow SU permission.
There are scripts / code that have a deliberate delay and must run after Synapse. These are not user optional.
Synapse has a stability check on boot. You may get "synapse boot cancelled".
Thermal throttling will be trying to limit many things, let the device settle
OTHER PARTY CAN NOT HEAR VOICE ON SPEAKER PHONE
It could be a conflict in the system/etc/mixer_*.xml. I don't know for sure, but if I exclude the sound mod, then this "fixes" the problem.
As I cannot reproduce the issue (and the majority), then the audio mod stays.
Unfortunately, making it optional would require to build kernels without and create much more work for many device I don't actually use.
Either live with it, or use another kernel. Sorry.
"NO UCI SUPPORT"
It's a ROM busybox compatibility issue !!
Re-flash kernel as per Installation Instructions. (kernel install zip flashes proven busybox binary to /system/xbin)
BACKUP / RESTORE ISSUES
It's a ROM busybox or sqlite3 compatibility issue !!
Re-flash kernel as per Installation Instructions. (kernel install zip flashes proven busybox binary to /system/xbin)
BACKUP & RESTORE
DO NOT restore profiles from different kernel version
Refer to THIS post for "how-to" screen-shots
Refer to THIS post for a "how-to" video
LOADABLE MODULES AREN'T WORKING
Check your /system/lib/modules directory. Are any ____.ko present?
Did you flash a ROM or wipe the system partition at any point? Doing this will remove them !
Re-flash the kernel will install the modules.
If modules aren't installed after flash, then re-flash and manually mount system in recovery first.
You can check running modules in terminal with:
​lsmod

CPU POWER CONSUMPTION
The Samsung Exynos 7420 Deep Dive - Inside A Modern 14nm SoC (by ANANDTECH - Andrei)
F2FS SUPPORT
It's not needed. You wouldn't see any difference or measure much, if anything. Not worth the potential trade-off. This is not eMMC anymore
Storage Benchmarks
STUCK ON SAMSUNG BOOT LOGO AFTER FLASH
Ensure you flashed the correct kernel for your device model
Ensure your download is not corrupted. Check MD5 hash or re-download
Your current base firmware (ROM, boot-loader version etc.) may be incompatible - UPDATE to latest with Odin and try again.

BATTERY TIPS (require updating !! )
Try some (or combination) of the CPU MULTICORE features in Synapse:
HMP profile = Default (values are battery orientated)
Power Aware Scheduling (slight performance cost) = Enabled
HMP LITTLE Packing (slight performance cost) = Enabled
PEWQ (power-efficient workqueue) (slight performance cost) = Enabled
Set A57 & A53 Interactive governor profile = Battery
Set Input-Booster for key/touchkey profile = Battery
Multi-tasking: enable UKSM & "low" or "quiet" profile (slight performance/battery cost)
PERFORMANCE TIPS (requires updating !! )
Set A57 & A53 Interactive governor profile = Performance
Set A57 & A53 Interactive governor = Turbo Mode (battery cost)
Set HMP threshold profiles = Stock or Performance
Once in a while:
Optimize Databases
FSTrim​
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
Use a stock UNMODIFIED ROM for your device variant
No tweaks, Xposed or other CPU control apps installed
Follow the TROUBLESHOOTING GUIDE
ASV_GROUP (ALL DEVICES ARE NOT CREATED EQUAL)
THIS is an example from my Exynos5420 source. Similar idea for Exynos4
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Disable any CPU MULTICORE options in Synapse
Disable any Battery profiles in Synapse. Set to default or Performance.
Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
HIGH CPU/GPU OC == excessive heat == thermal throttling == reduced clock frequency == DECREASE PERFORMANCE
DYNAMIC MANAGEMENT OF DIRTY PAGE WRITEBACKS
by Christopher83
This feature allows to have two different intervals for dirty page writebacks and to dynamically manage them when the system has been resumed (it's active) or when has been suspended.
Three new procfs parameters are exposed inside /proc/sys/vm path:
dynamic_dirty_writeback is the activation status of this feature, set 1 to enable it, set 0 to disable it and use the standard behaviour
dirty_writeback_active_centisecs is the interval for the dirty page writebacks when the system is active (screen on)
dirty_writeback_suspend_centisecs is the interval for the dirty page writebacks when the system is suspended (screen off)
This feature is in part inspired on Francisco Franco's PATCH

Synapse > Network > DTIM (both screen ON & OFF) = 1
Synapse > Network > WIFI Power Mode (screen OFF) = FAST

@UpInTheAir needed to create these threads to compile them for Synapse. He contacted me to close these as soon as he made them until he is ready with the finished product. Have patience.
Also I would like to apologize to UITA as the last ban may have been due to a system glitch where the signature was restored upon return, so was unjust. I have seen these glitches before and better communication might have prevented the error. We will do better going forward!

SkyHigh KERNEL REBORN - v5.6 released !!
SkyHigh KERNEL REBORN - v5.6 released !!
Hi fellow members.
Please find my latest release for SkyHigh kernel. There are many many changes, both visually (more / improved features) and a upgraded engine (better performance & efficiency) since I last publicly released. Far too many to talk about. . . .
And no - it DOES NOT fix call audio issue with leaked UX ROM. I believe it to be a ROM issue n!
Please note that although I have taken as much care in building and testing by my friends and I, the kernel may still not perform as hoped for you. Could be due to various factors including (but limited to):
hardware quality
firmware installed (incompatibility)
user habit (how you use the device)
apps & mods installed, customization's (conflicts)
user kernel settings (read them carefully - if in doubt == defaults)
As noted in Post #3, I may not have your device variant and not be always able to help either. In the end, sometimes SkyHigh is just not meant for you . . . .
If you have issues = = READ & FOLLOW ALL Posts #1-3
READ & FOLLOW THE INSTALLATION INSTALLATIONS EXACTLY (or else device will not boot)
Also please note (as per OP) the support for UX based ROMS is still in beta. I have personally tested very briefly, and also some of my friends (not all variant)
Enjoy
UITA

I see your posts in various development threads. . .
From your history, seems you're never happy with anything.. .
THREE options:
1. Read and follow what's requested of YOU top of Post #3.
2. Use a different kernel
3. Use stock

Anyone using a Grace UX rom with this kernel and if so can you link me one that's working? Been wanting to try it out.

UN-recognised Developer of my SkyHigh Kernel v5.6.x powered SM-N920C

[Kernel][21.08.2021][4.14.243][Android 11] Kirisakura 1.3.9_R for OP7/Pro aka Guacamole

Kirisakura-Kernel for the One Plus 7 Pro
Hello everyone,
Kirisakura - Kernel is designed to bring a handful of beneficial features to the device, while ensuring excellent performance and smoothness to get you safely through the day!
This project aims to keep most of the subsystems updated, way ahead of the stock kernel, thereby improving security and performance, while keeping stability as the foucs during testing! This includes Linux-Stable, CAF-Upstream and kernel/common.
Kernel Control Flow Integrity (Kernel-CFI), which is achieved by linking the kernel with LLD and Link Time Optimization (LTO), more precisely ThinLTO, are quite unique security features.
The only kernels made by OEMs offering this security feature by default are the ones for the Pixel 3, 4 and 5 devices.
The recently released Kirisakura-Kernel for the OnePlus 8 Pro was featured on the XDA-Portal due to the inclusion of CFI. The featured article explains CFI in great details, is easy to understand and definitely worth to read.
If possible the latest Kirisakura-Kernel releases for various devices aim to include CFI in enforcing mode so users can benefit from this security features.
Another security feature is Shadow Call Stack (SCS). Similar to CFI, only the Pixel 3, 4 and 5 kernels use this security feature.
SCS is another security patchset that is aimed at preventing attacks via return oriented programming (ROP).
ROP is a technique where the attacker gains control of the kernel stack to overwrite function return addresses and redirect execution to carefully selected parts of existing kernel code.
If you´re interested here are a few good links:
Google Security Blog explaining SCS.
LLVM doc about SCS
Android DOCs documenting SCS
If reading about upstream in the paragraph above got you curious,have a read about Linux-Stable and why it is important here. The stable-process is not the same for every subsystem, but the general idea, rule of thumb and benefits are applicable for other subsystems as well.
Quick explanation of CAF-Upstream. CAF is short for Codeaurora-Forums. This is the place where development from Qualcomm for their SoCs happens. This includes the Snapdragon 855/+ that´s built into the different SKUs of the OP7/T/Pro.
The kernel-bases available on the Codeaurora-Forums, are basically the foundations OEMs use, to build their own kernel additions on top for devices featuring Qualcomm SoCs.
The Qualcomm developers push regular updates to the bases of the different SoCs, a bit similar to how Linux-Upstream works. Most OEMs usually stop updating the initial base after the phone is released, and only cherry-pick certain commits to be in line with the android security bulletin.
This kernel focuses amongst the other features to merge CAF-Updates in a regular manner, to provide updates, improvements and enhancements for SoC specific drivers and subsystems! This might take a while, because a lot of device specific testing is done on my end to ensure stability.
The EAS implementation from 4.19 CAF (sd865/+) was ported to this kernel. There are several interesting mechanisms qcom worked on. The basic layout of the soc architecture ( 4xLittle- , 3xBig- and 1x Prime-Core(s)) has not changed from SD855 to SD865. That means instead of revolution there was a very nice evolution the scheduler underwent.
The kernel includes a lot of improvements and contributions from other developers as well. Without this kernel would not exist.
Many of the improvements originate from @arter97´s, @kdrag0n´s, @RenderBroken´s and @Sultanxda´s work. Many others contributed in some way or another to this kernel.
A big thanks to all of them at this place!
Now lets continue with a list of features in the next paragraph!
Main Features:
- Based on latest kernel sources from OnePlus for Android 11 primarily intended for use on OOS stock firmware
- Upstreamed against latest CAF
- Linux-Stable-Upstream included to latest 4.14.243
- compiled with Clang 13.0.1 prebuilt from Google
- built with -O3 speed optimizations
- Link-Time-Optimization (ThinLTO)
- Kernel Control-Flow-Integration (CFI)
- Shadow Call Stack (SCS) Security-Feature
- Use ThinLTO which was first used in the Pixel 4 XL Android R-Preview Kernel instead of full LTO for full program visibility (needed by CFI)
- fix CFI-Violations found in various subsystems like OnePlus/device specific drivers and qualcomm drivers
- Link the kernel with LLD and use RELR-Relocation
- include important fixes/improvements from kernel/common
- Flashing the kernel will keep root!
- Anykernel zip is based on the Anykernel3 repo from @osm0sis
- include vDSO 32 patches to improve 32-bit performance
- devfreq backports from 5.4 (sd 888 qcom kernel base)
- disable various debugging configs, that are not needed in a perf build kernel according to google.
- Removed RTB(interrupt) logging entirely
- disable selinux auditing (we don´t have to adress selinux denials running a stock rom)
- fix several coding issues detected by newer Clang-Toolchains
EAS related features:
- EAS scheduler backported from 4.19 CAF and 5.4 CAF / QCOM SOurce(SD865/SD888)
- adjust powerhal to account for scheduler backports
- disable autogroups and use cgroups for more efficient task placement!
- updates from kernel/common
- scheduler updates from Googles Pixel kernel
CPU related features:
- dynamic WALT-Windows based on FPS (more information here and here )
- Power saving workingqueues enabled by default (toggleable in EXKM)
have a read here: https://lwn.net/Articles/731052/
this complements EAS in general
- Change various drivers ( MM, audio) to user power efficient workingqueues. This should work well in conjunction with EAS
- include cpuidle patches from CAF
- improvements to cpufreq/times/stats
- improve memory allocations in binder driver
- vdso32 patches as found on Google Pixel devices (brief documentation here)
- arm64: lse: Prefetch operands to speed up atomic operations
- improve bluetooth performance
- improve /proc performance
- remove VLA-usage (info)
- option to disable touchboost in msm_performance
- disable coresight, enable coresight placeholder and add proper disabled clocks for sd 855
File System related features:
- improve memory allocations in sdcardfs

Scheduler Setup and Kernel Settings:
- kernel setting get automatically applied at boot
- an AK3 helper module is automatically installed during flashing ( do not remove it in magisk manager)
Misc Features:
Wakelock Blocker:
- advanced wakelock blocker with the ability to block any wakelocks (dangerous, use with caution)
- please read [URL="https://arstechnica.com/gadgets/2018/08/p-is-for-power-how-google-tests-tracks-and-improves-android-battery-life/"]this for further info
- blocking a kernel wakelock should only be done in case of firmware incompatabilities (WiFi network at work (can´t be changed) causes deep sleep to not work on the phone.) That´s the only use case I see for this feature. The kernel does not features this to improve battery life!
Requirements
- unlocked Bootloader
- USB-Debugging in developer options enabled
- latest adb and fastboot binaries
- working adb and fastboot environment
- magisk root
- be aware kernel is primarily made for OOS, certain custom roms might not boot or have features broken
How to flash the Kernel:
1. Download the latest kernel.zip
1a. Optional: While it may not be necessary all times, you may want to restore stock boot.img, re-root with magisk and optionally install twrp.zip if coming from another kernel. Before reporting issues make sure you do that! Thank you!
1b. Optional: The stock kernel can be restored by either dirty flashing the firmware.zip or by restoring the stock dtbo.img as well as boot.img. Those can be extracted via payload extractor from the firmware.zip.
2. Make sure to use latest Magisk stable.
3. Flash the kernel.zip via latest EXKM or FKM app. Alternatively via TWRP if TWRP is working.
4. Reboot and profit. After flashing the kernel in magisk manager there will be a module called AK3 Helper Module, do not delete it.

Kernel Special Features:
Version Information
Status: Stable
Created 2019-05-26
Last Updated 2020-09-26

Question: Is root preserved when flashing this kernel?
Answer: My kernel.zip keeps a device rooted by magisk rooted.
Question: How do I return back to stock kernel?
Answer: Flash boot.img as well as dtbo.img extracted from the full firmware zip.
Question: My WiFi is not working after flashing the kernel. I can´t toggle it on.
Answer: That means something happened to your device, that is causing some stuff to not get loaded properly when booting. I ran into the same issue once. Read through the thread to find the cause.
I wrote a guide in the linked thread, that explains step by step, how to return to a working condition without the need to wipe the phone completely.
Click the following link to find the post: post is linked here
Question: How to report bugs properly?
Answer: Have a look at post #3 in this thread. The linked guide is a pretty good starting point.
Before reporting any bug make sure you´re not using any mods, magisk modules, scripts or other modifications that alter various functions like sound mods etc.
Try to describe the issue as detailed as possible! Give your exact setup, like rom, magisk version, kernel version.
Is the issue reproducible? Does it happen frequently?
Provide logs, otherwise debugging is a lot harder. If you can already reproduce the issue and provide logs it greatly limits the amount of time I have to spent until I figure out how to reproduce it.
If the device force reboots/randomly reboots (that means you see the bootloader unlocked screen!) provide a ramoops file.
Easiest way is immediately after booting up, with a root explorer navigate to sys/fs/pstore. Copy the contents to your internal storage, zip it up and send it to me.
If the issue happens while the device is running provide a dmesg plus a logcat that you take while/shortly after the issue happens. This will log what´s running in the current session. Try to be as detailed as possible what´s happening when the issue appears. It will also help me in reading the log!
To easily get a logcat in case of a crash take a look at this post:
https://forum.xda-developers.com/showpost.php?p=79462002&postcount=1566
Big thanks to @jcmm11 for it
Here´s a tasker task to automatically copy /sys/fs/pstore on each boot to internal storage. Be advised these files get also created on correct reboots.

thanks @jsauder2 for this little trick

Useful Resources
How to report bugs:
It is incredibly useful if bug reports are done in a proper way. That saves everyones time and will ultimately lead to a faster bugfix (hopefully).
The following guide from @nathanchance is a very good guideline on how to properly report a bug!
https://github.com/nathanchance/Android-Tools/blob/master/Guides/Proper_Bug_Reporting.txt

How to convert your OP7 Pro to use f2fs on /data:
Do this only if you know what you´re doing. This guide works even on stock rom with stock kernel.
OP7 Pros Kernel as well as the fstab support f2fs by default.
If you´re using Kirisakura-Kernel starting with version 1.5.0 you will use the latest upstreamed f2fs implementation. Otherwise you´re running that´s a bit outdated and also a bit slower.
Google did put a lot of work in f2fs and that benefits here greatly too.
1. Backup your data and transfer it to an external storage device, because we will now erase everything on /data
2. Boot to TWRP
3. Go to Wipe - Advanced Wipe - Select "data" - Change file system - f2fs - confirm <- This will erase all userdata including your internal storage (pictures, videos, music etc)
4. Boot up and set up your device freshly.
5. Enjoy f2fs on your OP7 Pro

Well, I wasn't planning on unlocking the bootloader in this phone.... Going to now that you're here! Thanks for your hard work

Dude,
So pumped to have you on the OP7Pro! This is shaping up to be a really well supported device!
Sent from my OnePlus7Pro using XDA Labs

So hey everyone
want to lose a few more words here. I spent quite a bit of time getting this up as quickly as possible. I never had an OP device until now. So I needed to get familiar with it and get the hang of it.
I spent quite some hours and most of my free time since thursday, in the hope of getting this up before the weekend ends. Some people I spent less time with, were not quite as happy about this decision, but so be it.
I had quite a bit of experience with the CAF merge from the Pixel 3 XL, that made things a bit more easier and smooth. Upstreaming to latest linux-stable was quite a pain, because there are several commits, which cause the device to boot straight into Qualcomm Crash Dump mode.
In the end I got to 4.14.122
It´s still early here on this forums. So far now use adb sideload to install the kernel. The magisk module needs to be flashed otherwise some things, like accessing battery settings isn´t working, because of selinux-denials. If you can live without it, I´m pretty sure you can run this kernel also unrooted. But for the things I mentioned magisk is required, because you need to flash the companion module.
Once TWRP data decryption works, we can flash the zip simply in TWRP. Once EXKM and FKM are updated, we should be able to flash the zip via the apps too
For now it´s this way
I have a few more plans for this kernel, like wireguard, adding maybe some (not to much) features to it, maybe use f2fs and bringing it to latest state. I´m pretty sure I find more stuff as well.
The kernel is way more snappy than the stock kernel for me. It uses some of the EAS improvements from my Pixel 3/XL kernel, which can be utilized on this newer kernel base as well.
I confirmed it with a few little tests/benchmarks and for me the difference is night and day.
I´m running the device always full resolution and 90fps
If somebody can confirm, this it would be really great
If you encounter bugs, please take a look at post #2 and #3
there is a bit more in the kernel than the pure OP. I´ll update it the next few days
I wish everybody a nice weekend.

Great to see you here on this device!

Welcome to the world of OnePlus! This is my second device from Oneplus and finding it an awesome device. Sad to see HTC go down the tubes.

great to see you here freak!

Great news. Just flashed all working well so far

Great to see you here freak & we all appreciate you giving up your time. I'm staying stock until Stable Twrp is released, but as soon as it is I'll be using your kernel.....

@Freak07,
Never thought there would be a day that we would both be on the same device again.. ( I technically haven't gotten the device yet.. waiting till next month),
But glad you are here man. Your work is awesome... Now I got someone to cherry pick from JK man.............
BTW< stop by Slack every once in a while man.

Looks promising, I'll flash it! Good job!

hey bud message me on telegram guess we meet again lol im working on my stuff now glad to see you here @Freak07 and eleminator

Wow it's so nice to see you here! Never thought I'd see the day haha

Hey buddy,
I would love to see WireGuard support as I use it all the time. I much prefer the kernel implementation as it doesn't consume any battery compared to the userspace version which does.
In terms of F2FS are you also going to update in line with how Arter97 does things and also implement his Rapid GC commit and subsequent changes?

Updated with custom boot image from @uluruman

Development [KernelSU][M127F] My personal/custom Linux kernel.

Your warranty is now void. 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 image 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.

About​The published (linux) kernel is mostly unmodified – some changes were done to integrate KernelSU with our kernel, fix some compile errors and warnings. Outside of this, these are key modifications done via custom defconfig:
Added more governors: ondemand, powersave, conservative, performance
Add HAFM P-state driver for Exynos CPUs (it might not work with our SoC, but I've added it just to test that).
Add support for CD-ROM in kernel: devices (/dev/block/sr0) and filesystems (ISO9660, UDF).
Enable BTRFS filesystem support in kernel.
Enable write support for NTFS filesystem in kernel (might be experimental).
Generic (non-Samsung) kernel hardenings.
Disable known Samsung security modules and make DEFEX kernel-only.
Enable more compression algorithms (crypto, kernel).
Enable /proc/kcore.
More thermal governors (fair share, power allocator).
ConfigFS: more gadgets, enabled other related features.
More DEVFREQ governors.
Enable OSS sound subsystem in kernel.
…and some other experimental features I've enabled just to test them.
NOTE: Some modifications done to kernel might be useless for some/most users (e.g. enabling OSS sound subsystem, CD/DVD support), some might not even affect Android at all, but I've enabled these to experiment with kernel possibilities and a bit for Termux/Linux integrations.
How to install​Using unpack_bootimg and mkbootimg binaries.​
Install/download/build android-tools for your platform.
Get a boot image from somewhere (e.g. firmware download sites, software to download it from Samsung servers directly) for your phone.
Use unpack_bootimg on original boot.img:
Rich (BB code):
unpack_bootimg --boot_img original_boot.img --out out_dir --format=mkbootimg > mkbootimg_args.txt
Replace out_dir/kernel with the kernel image you've downloaded.
Repack with mkbootimg:
On Linux:
Rich (BB code):
sh -c "mkbootimg $(cat mkbootimg_args.txt) --out repacked_boot.img"
On Windows (copy content of mkbootimg_args.txt and paste it instead of <flags>):
Rich (BB code):
mkbootimg <flags> --out repacked_boot.img
Flash the repacked_boot.img image.
Supported devices​Only Samsung Galaxy M12 model M127F (OneUI 5.1) is supported – M127G and others might not work with this kernel.
Kernel source code​
kernel: https://github.com/SpacingBat3/android_kernel_samsung-m127f_a13
branch: 4.19.111-samsung+kernelsu
defconfig: exynos850-m12nsxx-patched-devel_defconfig
Changelog (for prebuilt kernel)​
2023-04-23 – Initial build, for OneUI 5 (most likely was broken).
2023-05-07 – Build for OneUI 5.1.
Currently known issues​
KernelSU seems to be a bit unstable and enters Safe Mode after a longer use; I currently have no idea if this is on kernel side (and I should be fixing it), issue caused by modules or instability in KernelSU. There are however no visual crashes, it happens in the background and is barely noticeable. KernelSU haven't entered the Safe Mode since the update to OneUI 5.1, so it is highly probable this issue is gone. Seems that Samsung has fixed it?
Plans / TODO​
I might try fixing compile errors with KVM in kernel and overall enable it, hopefully that'll be enough to get stable VM acceleration in QEMU (Limbo on Android). I'm not sure if I'm skilled enough to do so through, but at least I'll give it a try if I'll be able to share some time for that.
I'll try cherry-picking various commits for KPROBE from upstream in order to fix it for KernelSU. This was not enough for me to fix KPROBES, guess the issue is not outdated KPROBES, so it will take much more effort to fix it, maybe even not worth it.

The kernel was updated for OneUI 5.1. The previous builds could also not work, the current ones should be working fine. I've also added missing firmware to the source code which was not commited before due to .gitignore took from upstream kernel.
