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.

New kernel , i'm going to test now

Tried both with my S8 ROM port.
Boots very slow
When devices i booted it takes some seconds till phone freezes and than reboots!

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?
EDIT: for now I back to my previous kernel...sorry....
Thanks!

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! ?

After flashing 1.5.0 I'm still at 1.4.0 :/

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

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.

Asop or OOS only kernel?

/* 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.

Keep in mind this is early build and many los features are not merged yet do not report those as bugs as they are not device specific and will be resolved
Also here are some screenshots
Also big thanks to everyone who supported this and other projects since lineageos 15.1 since i do this in my free time and donations help offset server cost and get me coffee

Wow, you just keep this device alive. Cant wait to try this Rom(im currently downloading...) Will report in a few days how it is

Holy moly, that was real quick. Thanks for this ROM! Do you think you could fix the microstuttering that sometimes appears on LOS 17.1? I see you have an EAS implementation in the works but only you know the real status of your tree.
Alternatively, could you provide a no-op performance profile so we can tweak the interactive governor through a kernel manager? When I change my governor settings for my custom ones microstuttering goes away until they reset to default after a while even if I enable apply on boot, and the default performance option is janky when doing anything more intensive than scrolling a webpage or through the system UI. Sometimes playing games is impossible because it runs smoothly but randomly jumps.
Again, thanks for your ROM. We are blessed to have a dev like you working on this old horse

So far ROM is awesome smooth and fast ,only problems for me at least:
1-brightness slider
2-calls problem can't hear or talk and can't record in such apps like WhatsApp
Thx for ur awesome works so much appreciated

Hi,
Did anybody try to dirtyflash from 17.1? I had no luck so far...
And again, big thank to Ivan, for the rom and keeping device alive!!!!!

I don't know if you mean the same thing, but at least Pokemon Go "jerkiness" can be completely fixed by changing GPU powersave mode from "coarse demand" to "always on".. But you need some adjustable kernel like Morokernel to be able to do this, and Moro is not very good with recent LOS versions.
I don't know what the issue with "coarse demand* is.. it turns off GPU power after 100ms of idle. That certainly shouldn't happen during gameplay when there's constant movement on screen?

Thanks for responding. Changing to always_on does help a little but it makes the phone MUCH hotter...or is it my idea?
The phone is hotter and it still stutters, I tried changing the I/O schedulers to less intensive noop and tweaking the interactive governor helps but then it resets itself back to stock settings no matter what I do. But no matter what, there is always at least a bit of microstuttering. It is ruining the experience on this otherwise perfect ROM.
Also the custom kernels are using a different kernel/binary blob base that doesn't work with this ROM family anymore. I personally don't want to delve in the headache of merging commits and fixing build failures, it means downloading yet another kernel for yet another SoC and my space is kinda limited right now because I already maintain a device.

Hmm. I'm actually currently on FloydQ rom. It is very smooth with Moro and this "always on" mode. Battery use is very minimal, phone does not get hot.
FloydQ is using the older code base so Moro works. But earlier I was using some older LOS 17.1 beta with Morokernel and it was smooth. The later versions (with newer code base) stuttered..
Hmm.. perhaps there is some bug causing entire device to halt for over 100ms? Then coarse_demand mistakes this as idling and powers off the GPU, making things even worse.

I can't see call screen when someone calls please fix this

As it says on the main post, it's pointless to report a bug without including:
a) Logcat
b) proc/last_kmsg (or proc/kmsg)
c) data/tombstones
d) dmesg
as he can't possibly recreate every issue.

Thank you !
I will test with NikGapps

please someone upload it on sourceforge ((((
i cant download from google drive

I am switching to another ROM and flashing echofix

Wattsensi said:
Does this ROM have all the bugs and instability older Lineage ROMs had, or it works as a daily driver? Apart from the fixable echo problem, do calls work well? I am considering switching ROMs to instal ThundeRStorms Kernel if I can't solve this issue from userspace. as a bonus I get EAS.
Click to expand...
Click to collapse
Well.. I'm probably the wrong person to answer, as I have never encountered the echo or volume problems on LOS either. And I use this as my work phone so I call quite a lot.
But still yeah, FloydQ feels very stable. I think it's mostly binaries moved from the S9+ rom, as it has all Samsung proprietaries working (like VoLTE calls).. I assume echo cancellation as well. And it passes SafetyNet out of the box, you don't necessarily need Magisk to run bank apps etc.

Well, I flashed Resurrection Remix and indeed, the microstuttering is gone! Thanks for the recommendation.
EDIT: The culprit seems to be the N935KKKU4CTH1 rebase, running a ROM previous to their inclusion makes the problems disappear

[Kernel][05.01.2023][Android 12] Kirisakura 1.0.1_S for Asus Zenfone 7/Pro aka Tequila

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!
Now lets continue with a list of features in the next paragraph!
Main Features:
- Based on latest kernel sources from Asus for Android 12 and intended for use on the latest Asus Stock-Firmware
- compiled with Clang 13.0.1 and built with -O3 speed optimizations
- Linux-Stable-Upstream included to 4.19.2240
- CAF base for the Snapdragon 865/+ (SD865/+) updated to upstream CAF
- Kernel Control-Flow-Integration (CFI) andLink-Time-Optimization (LTO) ported from 4.19 kernel/common and Pixel 5/4/XL Kernel
- 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 Asus/device specific drivers and qualcomm drivers

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.

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:
https://dlcdnets.asus.com/pub/ASUS/ZenFone/ZS670KS/UL-I002D-WW-30.41.69.66-user.zip

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...
forum.xda-developers.com
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
