Note:
Kernel Developers: I would like to ask you to merge this patch to your kernels, because it is essential part of MultiROM (MR) - it allows MR to boot any kernel without changing the boot partition. I realize that it is no small request, but the patch is not big, touches relatively stable parts of kernel and should not cause any problems outside its intended function.
The Patch:
You'll need to cherry pick a total of 5 commits (if anyone feels like squashing them to help me out, feel free to link me to it).
Cherry-pick against: http://github.com/multirom-nexus6p/android_kernel_huawei_angler.git on the branch 'mm2'.

Related defconfig options, and their explanations:
Code:
CONFIG_KEXEC=y # Enables the Kexec SysCall to allow loading the new 'secondary' kernel into memory
CONFIG_KEXEC_HARDBOOT=y # Enables the HardBoot flag, which allows 'cold-booting' a new kernel
# CONFIG_ATAGS_PROC is not set # Prevents potential atags related discrepancies, this must be either removed or commented out
CONFIG_PROC_DEVICETREE=y # Allows us to read out the kernel config, and tell that the kernel has all the necessary configs enabled (read out from /proc/config.gz)

Known BUGS!
Post reports, i will fix.
Standard disclaimer:
By installing this kernel YOU will take full responsibility for any damage to your device!
Hardware or software! no one forcing you to install it.
So please do not blame me if you read wrong! or didn't read at all the instructions that i have written for YOU.
But you can feel SAFE to use it, as I test every release on my phone!
Before I publish it for download.
Your warranty will be void by installing custom kernel as my.
Kernel Sources:
KERNEL GITHUB
TO DOWNLOAD GO DOWN!!! YES MORE DOWN...(do i need to repeat?)
How To Install:
You will need to have device with Latest Recovery installed! Please install the 3.1.1.x BUILD!
>>>Here is the Recovery you need!<<<
Old recovery can corrupt your DATA partition as my kernel using latest F2FS driver. new recovery has updated driver.
YOU MUST UNLOCK OEM BOOTLOADER!!! OR YOU WILL BE STUCK ON BOOT!
Refer to other threads for recovery install process and for oem bootloader unlock.
Download kernel, upload it to your SDCARD, anywhere.
Always have STOCK Kernel for your ROM!
Reboot to Recovery.
THINK AGAIN! did you made backup? NO!!!!??? DO IT NOW!
If you had any other Custom kernel, Install STOCK kernel or dirty flash your ROM,
to clean any trace from other kernel. then install ROOT/Magisk if you wish! then install my kernel ALWAYS THE LAST.
Do not clean any cache or dalvik (needed for ROM only!).
Reboot!
If you wish to UNINSTALL my kernel, there is a uninstaller ZIP for you.
it's will remove all ramdisk changes, and install last 4.1.6 stock kernel, preserving ROOT if was installed!
Have Fun and report.

One for ME :silly:
Some INFO:
ONLY for OP3T!!! do not do this for OP3 model!
If you have Verity Alert on boot that says it's not enforced. and you like to fix it!
Here is how to by @RyperX and @Leicxan
Download modem + firmware 4.02 and the 4.1.6 here:
https://forum.xda-developers.com/oneplus-3t/how-to/firmware-modem-collection-flashable-zips-t3565535
Reboot to Recovery!
Connect your device to PC with USB cable.
1. Install modem 4.0.2
2. boot to fastboot/bootloader (from recovery menu)
3. apply the 2 commands in this order ("fastboot oem disable_dm_verity", then "fastboot oem enable_dm_verity") using fastboot exe file in your PC
C:\Users\admin>fastboot oem disable_dm_verity
...
OKAY [ 0.031s]
finished. total time: 0.032s
C:\Users\admin>fastboot oem enable_dm_verity
...
OKAY [ 0.032s]
finished. total time: 0.034s
C:\Users\admin>
Click to expand...
Click to collapse
4. reboot directly to recovery again using the volume keys and then power key to select recovery!
5. flash modem 4.1.6! or 4.1.7!
6. reboot
Warning of the verity not enforced is gone.
And one more for me
Great you are here
Lets get the OP3t the same lifetime as our LG G2 had
Let the game begin....
Hmm definitely interesting... Will check this kernel out! Nice work by the way...
Happy to see it public ?
Sent from my OnePlus 3T using XDA Labs
Seems amazing!
Just installed, will edit with small review after few days.

Congratulations buddy [emoji111]
Congratulations man
Thank you so much.
Daym, how many kernels did you combine into this ? xDD
nice nice nice .... waiting long time for this
good job
want to try it....on my op3t
long long long time ago i had this awesome kernel on my Samsung S3.......Damn.....long time ago
Thanks Dori for the Nougat release
cheers
Can this be made for the op3?

It's a unified build working perfectly on the OP3.
@dorimanx just wow.
I have never encountered this kind of smoothness with my op3. I'm using Open Beta 18.
Not sure how this kind of level of buttery smoothness is even possible to achieve.
Hands down, this kernel is on whole another level of smoothness for op3.
Thank you so much! Any plans to support LineageOS?
Edit: CPU governor was set to performance by default but still very well performing kernel
First LG G2 with the Dorimanx power and finally with OP3, back to the heaven.

How many users are there in this kernel and what is it with custom ROM?
* Go to User Statistics.
With this kernel, the following information is sent once to the developer's server at boot time.
variant, android serial number(not device serial), name of current firmware(ROM), country code, kernel version
* This information is Android apps can see without any special permissions.
* If you suspect other information transfer, open the '/res/synapse/actions/addon' file.
Description for AOSP ROMs
If you are using another developer's custom kernel, or if using ramdisk is corrupted kernel, you may encounter a bootloop or an unknown problem.
If you have a bootloop problem, flash the PRIME kernel after first flashing the builtin kernel in your ROM. (Or flash the ROM again)
This kernel is flashed AnyKernel method, for all kinds of AOSP ROM support.

How do enable donation-only add-on features?
I only receive donations from your heart.
Do not donate if you intend to unlock synapses.
If you are unable to make a donation of 5.0 USD or more due to economic reasons, please do not donate and request me to unlock Synapse. Then you can use all the functions of synapse without donation.
How to request synapse unlock
Please tell [email protected] the following:
- A matter that is difficult for you to donate(eg economically difficult countries, students without money or credit card).
- The first five letters or screenshots of the KeyCode on the Synapse's first screen.

Sorry, my fault. MTweaks was still running what interfered.
Flashed v1.4 with stock GPU drivers. running fine so far but boot time is still longer than with other kernels.
Could you add a global slider to under volt CPU and GPU by a certain value?
EDIT:
In Synapse at "Game Tuner MOD" and "Utility" tab the last few settings are not in englisch

The global slider is hard to implement, because of the UI structure of Synapse.
If you are not comfortable with the Voltage setting, you can get the desired result by returning to Synapse after setting in MTweaks. If you do not know what I mean, try it.
What if it takes a long time to boot? If it is a symptom that only takes longer in the first Bootanimation, it will not be a problem from the second since it recreates the dalvik (ART) cache for some reason.
If it takes a long time to boot each time, it may be because used the G935F ramdisk in this kernel. I tried BatmanROM, but I did not have the problem you said.
In the next version, i will separate ramdisks by variant like v1.3.0.
Korean in the Gametuner-MOD and utility tabs are donation-only functions.
I will translate English donors if they say inconveniences.

Ok, tried that with MTweaks and noticed that it was already under volted by my previous settings.
Noticed that there is no tab to disable wakelocks. Do you plan to add this?

Kernel-level wakelocks work when requested by an Android system or app.
It is not desirable to force such requests to be ignored.
My Note4 kernel has a wakelock tab. However, it was added because of the deep-sleep problem in some variants of Note4.
If there is a deep sleep (wakelock) problem in our S7, I will add a wake-lock tab.
Again briefly, the wakelock control should not be abused. So, if there are no related problems, I will not add them.
update to v1.5.0
Thanks for supporting AOSP! ?

If flashing was completed and there were no errors, it is not possible.
If you rooted or unrooted the kernel after flashing, the old kernel would have been restored.
If you do not know, Flash the kernel after rooting.

Indeed, I rooted after flashing the kernel, thank you ^-^
you do a fantastic job with all the feature you added in your kernel(thunderplug,eas, pwm flicker free, etc...). v15 is very recommended
Hey man, thanks for this kernel! I tried it on AOSP for RR which boots but I noticed that flashing this kernel, disabled the option to adjust vibrate intensity. The option in Sound is there but Settings Force Closes when clicking on it. The reason I need to adjust it, is the vibration is back to really strong vibration when touching a key. Hope this details helps. On latest Prime 1.5.0

Download your kernel.
And flash via twrp
It appears that I had removed important dtb files which made the kernel unbootable on walleye. I uploaded a new build to (hopefully) fix the issue. The new build should be called "Sultan-kernel-plus_20210418-fixup.zip".
EDIT: It's fixed and is safe to flash.

Yay... It boot now. But do u know why it same issue like other kernel ? (kirisakura, sultan old version,...) .
The issue is: when restart, the boot amination very very slow. Some time when the screen of press power key to turn on phone it take 3-5s to open (sometimes not usually) .
New build is up with some original commits. Nice!

I initially switched to PELT in hopes of lower jank. However I switched back because it turns out that PELT breaks live frequency stats and that jank is more or less the same as WALT with some proper tuning.
New build is out with lots of cool changes!

Kirisakura-Kernel for the Asus Zenfone 7/Pro
Hello everyone,
To keep it short: Here is Kirisakura - Kernel for the Asus Zenfone 7/Pro aka Tequila. The Zenfone line- up internal codenames are derived from alcoholic drinks, last year the Zenfone 6 bore the title Kirin.
I would appreciate if everybody that flashes the kernel, reads at least once through this opening post and the following ones.
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!
If you expect a custom kernel to magically improve your devices battery life manifold and this is your only priority then this might not be the right place for you. Instead there is an option called battery saver in the options of your phone.
However the kernel is built to keep battery life close to the same as you would experience the on stock kernel while being tuned to perform better in various UI related benchmarks. The same benches are used by google to verify and ensure UI smoothness on the Pixel devices. The scheduler is tuned to yield lower jitter and reduce jank frames.
If that got your curious, I welcome you to continue reading if you´re still interested!
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 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).
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 865/+ that´s built into the different SKUs of the Zenfone 7/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. OEMs usually stop updating the initial base after the phone is released.
This kernel focuses amongst the other features to provide the latest CAF-Updates merged 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 kernel includes a lot of improvements and contributions from other developers as well. Without this kernel would not exist.
A big part of improvements originate from @arter97´s, @kdrag0n´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!

- 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!
Other features:
- disable logging and debugging to make the kernel more lightweight in various places (includes binder, mm, vma, gpu, ipa etc)
- fix several coding issues detected by newer Clang-Toolchains
- implement ramoops functionality to be able to easily debug kernel panics
Feature section for the "non visible" but perceptible improvements:
- updated binder section (responsible for interprocess communication)
Flashing Guide, Download and Changelog
Requirements:
- unlocked Bootloader
- USB-Debugging in developer options enabled
- latest adb and fastboot binaries
- working adb and fastboot environment
- magisk root (magisk 22.0 or higher), usually magisk stable works best
- a backup of stock boot.img and dtbo.img so you can go back to stock conditions (simplest way is TWRP)
How to flash the Kernel:
1. Download the latest kernel.zip and make sure you have properly updated to the latest matching Asus Stock-Firmware. When the Zenfone 7/Pro receives an update it takes Asus a while to release the source code for the new OS and me a while to build a new kernel. If you don´t want to face any issues, wait until I either release an updated kernel or give green light because there were no kernel changes.
Always make sure to run the firmware the kernel is built for!
If you feel adventurous, make sure you have a backup ready!
2. Flash the kernel.zip via latest TWRP, EXKM or FKM app and do a full reboot.
3. Reboot and profit.

FAQ
F.A.Q:
Question: Why does the kernel version show as "unavailable" in settings after flashing it.
Answer: Asus does not allow for custom kernel names in their settings. Use a kernel manager to check the kernel version.
Question: Is root preserved when flashing this kernel?
Answer: Yes, the AnyKernel.zip will detect root and keep it.
Question: How do I return back to stock or another kernel.
Answer: Extract boot.img as well as dtbo.img from matching firmware you are on and flash the extracted boot.img and dtbo.img via fastboot. If you want to keep root flash back the magisk_patched_boot.img. Or dirty flash your rom.
Question: Why is having Magisk installed mandatory for this kernel?
Answer: Android 10s changes to partitions, doesn´t allow files in system/ and vendor/ to be replaced. This kernel is very far from the stock kernel. To account for this I can´t force load the stock kernel-modules for certain drivers as it happens on kernels that are closer to stock.
Instead we use Magisks function to overlay certain files during boot. Without a working Magisk environment the kernel cannot function.
Question: I have a phone that is converted from CN to WW and now there´s a warning from hardwarestub. Can I hide it?
Answer: Yes, I created a Magisk Module for those that want to hide the notification, so nobody needs to rely on paid apps.
The Magisk module can be found attached to this post.
Please note that refresh rate can´t be changed when the module is flashed. To able to change refresh rate or to remove the module, simple remove it in Magisk Manager and do a full reboot. I´ll attach it to the third post on this thread. There will be no support for this module from my side and no other support for converted devices.
Question: How to report bugs properly?
Answer: Have a look at post #3 in the linked thread. The linked guide is a pretty good starting point.
Before reporting any bug make sure you´re running on a stock configuration. That´s means you´re not using any mods, tweaks in kernel managers or other root tweaks , magisk modules, scripts or other modifications that alter various functions like sound mods, data traffic, sleeping behaviour, scheduler, magical battery tweaks 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 .zip of /asdf.
Easiest way is immediately after booting up, with a root explorer navigate to /asdf. 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!
and this one too
and the final one, because one never knows.
In case anyone asks, make sure to update to the firmware that dropped today.

Thank you for this! The phone is much faster, but also warmer in daily use. DeepSleep is perfect.

My phone runs on the same temperature compared to stock kernel.
Whats your ambient temperature? Maybe it's related to that.
Or it's coincidence and an app is stuck in background or got recently an update. Give it a reboot or maybe a few days.

I think this is due to the higher boost from the kernel compared to stock. There is also only a 4-5 degree Celsius difference. And only when using apps. You can feel it a little in your hand.
Reboot was carried out, of course. As I said, I think it's simply due to the higher frequencies overall and is completely within the limits.

The kernel doesn´t boost anything higher than stock. The powerhal and all boosts on input are unchanged compared to stock. Improved UI performance isn´t due to higher boosting.
Might be that some of the scheduler changes, paired with your unique usage lead to overall higher used freqs and the mild temperature increase.
Interesting that it seems to be the case for you.
Temps are basically the same on my end also during benchmarks, because I monitored temps while verifying the improved UI performance.
Thanks for the report! There is still more to come (also for the scheduler)
Thanks for your work, but I noticed than the consumption of the battery was high.
How can I flash the original kernel, I'm always on the stock a11 rom but I will flash soon the omnirom.

See post #2
Ok but perhaps, can you provide this file ?

No, it's best if you extract them yourself.
If you followed the instructions in the OP you should have a backup from boot.img and dtbo.img made via TWRP.
If you don't have them download the full firmware and extract them via payload extractor. You will be able to find that on XDA.
Edit: to flash Omni you need to have stock rom on both slots anyway. So just flash stock rom twice (that will restore original boot.img and dtbo.img anyway) and follow the Omni instructions!
Feature Documentation:
Here´s a brief documentation about some of the features included in the kernel that can be changed as the user desires.
They can be accessed via either terminal, scripts or for example EXKM manager ( tools -> user settings).
CPU-Frequency Limiting
Another option is CPU-Freq Limiting. You can now limit the CPU frequency to a few different levels with a sysfs interface. Original implementation is from @tbalden, I only changed it to be accessible via traditional root methods.
Main Switch:
sys/module/cpufreq/parameters/batterysaver
Set this option to "1" to enable the feature
Max-Frequency Selection (Input boosts, such as scrolling boost or app launching boosts will still apply, if touch boost restriction is not set to 1)
sys/module/cpufreq/parameters/batterysaver_level
Set this to "1" to restrict the max CPU-Freqs to 1,7GHZ/2,1GHZ/2,49GHZ (Little Cluster/Big Cluster/Prime Core)
Set this to "2" to restrict the max CPU-Freqs to 1,6GHZ/1,7GHZ/2,0GHZ (Little Cluster/Big Cluster/Prime Core)
Set this to "3" to restrict the max CPU-Freqs to 1,49GHZ/1,4GHZ/1,6GHZ (Little Cluster/Big Cluster/Prime Core)
Touch-Boost Restriction
sys/module/cpufreq/parameters/batterysaver_touch limiting
Set this to "1" to restrict the powerhal from boosting over the limit defined in batterysaver_level
Set this to "0" to allow the powerhal to boost above the values defined in batterysaver_level, but only during interaction with the Phone!

This is for example very useful during gaming to prevent additional heat, if not the highest performance from the CPU is required. Check if the game is running fine on level 1 or 2, and you´ll notice much less heat. Powerdraw will be reduced as well.
Another very useful trick while doing video calls or long extended navigation sessions with google maps to preserve battery or keep the phone from heating. Especially during summer if the ambient temperatures are high.
This is a very easy way to preserve battery or reduce heat without toggling the battery save mode in settings as that restricts background data usage, which can lead to delayed notifications.
Hey everybody,
I was a bit busy. Regarding new firmware update:
all changes from the 30.41.69.66 were already present in my kernel by merging CAF-Upstream.
So just flash away on the new firmware, link is here:

Hi,
I'm considering to get a zenfone 7 Pro but I would like to know do your kernel support permissive mode with fully /system write?

That's not related to the kernel any longer.
Permissive selinux can be set via terminal or a script.
Read/write is difficult on devices with dynamic partitions. Magisk modules are the easiest solution for this. They allow to systemlessly replace files during bootup.
However there are solutions like this:
[Closed] Universal SystemRW / SuperRW feat. MakeRW / ro2rw (read-only-2-read/write super partition converter)
Welcome to the one and only, the original, universal, System-RW / Super-RW feat. Make-RW / ro2rw (read-only-2-read/write super partition converter) by lebigmac Also known as: THE-REAL-RW, FULL-RW, EXT4-RW, EROFS-RW, EROFS-2-RW, F2FS-RW...

I'd be very cautious of stuff like this, it has the potential to mess up the device completely, so it can be only restored by wiping everything including all data on the device.
Any new updates? On the actual 78 firmware, the cores don't reduce the frequences on my phone.
Thank you
