Yes, keep it enabled. In the first post it clearly mentions it gets installed automatically when flashing the kernel zip. I am however completely baffled why you have the OnePlus 7 Pro Companion Module installed???

Yes, keep it enabled. In the first post it clearly mentions it gets installed automatically when flashing the kernel zip. I am however completely baffled why you have the OnePlus 7 Pro Companion Module installed???
Hasn't your phone been fully wipped. I am going to try to get rid of this annoying message to.@Freak07 I finally got the Kirisakura kernal flashed and working properly
First I did a complete uninstall of Magisk, then I use the Android Flash Tool to force flash the January update, updated the partitions and then disabled verity and verification (just to make sure the kernel flashed properly, I know you don't need to do this anymore, but no harm). When the phone rebooted, the error I was getting previously (your phone might be corrupted, press enter to continue) is now gone.
Flashed the patched boot image and your kernel flashed properly with EXKM.
p.s. I used the new kernel zip you provided with the ak3 update.
Thanks for all your help.
Yes, I resolved the problem. I explained what I had to do in post #694.
Thank you. It seems that wiping the phone is a must to get rid of this corruption message.
I am going to disable that socalled verify and verification next time while fastboot flashing the stock firmware.
Can I get this done once and for all?
I mean this time I disabled, will I lose data while disabling again next time?
Thank you, this flashing procedure is getting more and more complicated
no, you have to wipe only when disabling the flags for the first time. Just don´t forget to issue the command to disable the vbmeta flags everytime you flash a firmware which contains a vbmeta.img before rebooting the device. (everytime you flash a factory image or a full OTA.zip.)
That's what I mean. I know the AK3 module is needed and installed per the notes. Companion module is weird to me. I've removed it.
Sounds to me like you accidentally downloaded and flashed the wrong file on my androidfilehost at any point in time. The file you downloaded is on the most popular files of my androidfilehost account. But yeah you can remove that safely.
When flashing the most recent kernel.zip from the first post, there will only be the AK3 Helper Module in Magisk Manager module list, which you should not touch as you stated.
I thought it's not necessary to disable verity anymore with the new canary magisk builds?
I had thought too.
But it seems that to disable verify will do the good, in case that just like I flash Kernel over each other
It sure seems that way... Although I don't remember doing it. I'm sure it wasn't in the raviole version. Not questioning that.Sounds to me like you accidentally downloaded and flashed the wrong file on my androidfilehost at any point in time.

Didn´t you have to do this yourself to get rid of the device is corrupted warning? Unless I misunderstood your previous post?
I just answered the question whether or not a wipe is required on consecutive firmware flashes with vbmeta flags disabled and keeping them disabled.
Disabling the flags should not be needed any longer if everything goes according to plan, with the new magisk canaries that´s also correct. One of my testers runs with vbmeta flags not disabled and has no issues.
But given all the issues some people run into, when they end up with the device is corrupted message (seems also to happen when flashing/updating just factory images without the involvement of anything else, at least what I saw in the guide threads) there still seems to be something wonky.
I didn´t find any clue what exactly is happening, so unfortunately I can´t comment any more on this.
Has anyone else been experiencing issues where the P6P's screen is slow to wake?
I think it has something to do with deep sleep, and occurs whether tapping on the screen, or lifting to wake the device, it just seems to be stuck for a few seconds and then the screen comes on. I've been trying to isolate if an app or setting etc is causing it, but I haven't found the root cause yet.
If I don't change any settings via a kernel manager app (EXKM) then it doesn't occur either, which makes me think that it's related to the kernel in some way.
I've only noticed it after updating to January.
P6P, Rooted, Kirisakura.
Thanks!

No i haven't faced that myself at all.
Did you change any settings in exkm? You shouldn't have much more settings available stock kernel compared to my kernel.
Did you maybe disable any wakelocks in exkm?
Edit: just checked the thread you created. seems like people get this on stock too.
Last edited:
The only setting I change is the "Readahead kb" from 128 t0 256, and toggle "On" all of the other settings.
Could that cause any issue?
I'll try just loading the stock values without changing anything and see if this still occurs
I think I found what's causing it, seems to be using Zygisk in the latest version of Magisk.
If I have that disabled, I'm able to use EXKM to change any and all kernel options.
I'll report this in the correct thread, thanks!
I'm using FKM and the latest zygist Magisk. I have no issues changing kernel settings.
Interesting, any idea how I'd determine what's causing the issue? How I could figure it out by using Logcat?
You might see if anyone else on the thread is having the same issues with EXKM. Sometimes the kernel and the kernel managers don't play together well.

34Update to 2.4.0
Hey guys and girls,
Alright here´s the next update and it´s fine to flash on May firmware. As I suspected we already had all the changes for May by merging upstream.
I´ll include the changelog from 2.3.0 as well in this release post, since I think a lot of people flash the kernel on a monthly basis when the security updates drop. So this post pictures the changes going from 2.1.0 to 2.3.0! As I said 2.3.0 was kind of a final rehearsal to make sure everything is good for the May update.
I´ll put a remark behind changes going from 2.3.0 to 2.4.0.
This release is made for stable Android 12.1.0 May firmware. Not QPR Beta or A13 Beta!
Once I find enough time or QPR beta gets updated, I might update the QPR beta release. No plans to support A13 beta.
I also finished up the tables/graphs in regards to different binnings with the respective voltages on different tensor chips thanks to the dmesgs you all provided. I really want to put out a big thanks here to everyone for taking the time and participating. It was really great to see this kind of response.
I´ll provide them in a post in this thread soon.
So with that in mind we´ll get to the next paragraph were I could put those tables to good use.
A few changes from A13 Beta are merged to the kernel so we can enjoy the improvements on A12 ahead of time. Most of them aim to improve the scheduler and task placement.
However the recently dropped A13 Beta source contains a commit that can restrict max-cpufreqs based on PMU (Power monitor unit) reading. I setup this mechanism (lets call it "PMU Limiter") to mildly cut back max-freqs when they aren´t needed. It works quite well so far, with no performance impacts during scenarios where max cpufreq is beneficial. (e.g. app launching, camera launching, interaction etcetc)
That means if a certain threshold is not crossed the max-freqs will be restricted to 1,4GHZ/1,6GHZ/2,4GHZ (for little/mid/big cores). As soon as the PMU detects enough pressure, those limits will be lifted.
The frequency limits are based on tracing during various scenarios, benchmarking and also factor in the voltage table I was able to create. For example: 2.4GHZ for the big cores is the last freq step where a steady linear increase in voltage can be seen. Freq steps higher than 2,4ghz have a steeper slope.
Keep in mind CPU-Freqs shouldn´t be touched in EXKM/FKM or other kernel managers. They are controlled by various mechanisms now (thermal hal, powerhal, pmu limiter etc) and values will get overwritten based on input.
That means if you open the CPU section in a kernel manager, the maxfreqs will not be the actual maxfreqs that are possible. or the minfreqs might be raised. That´s normal and there´s nothing wrong if that´s the case.
Additionally to the previous changes tasks of rt, sf and ta groups are now biased to start on high capacity CPUs during app launches, interactions etc.
As usual, depending on your usage you may or may not notice a difference during these scenarios.
While tracing I noticed kswapd often takes 100% cpu share when reclamation is happening. Since we use an 8 core cpu, an additional kswapd thread is being spawned during boot, which increases throughput for kswapd in these scenarios. Reasoning behind this can be found here.
The trusty driver which connects to the fingerprintreader hal uses now a high prio workqueue when the phone is unlocked via fingerprint scanner. This means better performance, especially under stress. Keep in mind this is a kernel level change, it won´t magically improve fingerprint reader times manifold.
DAMON and DAMON-Reclaim were removed from 2.3.0 going to 2.4.0. I tested the feature privately and it unfortunately collides with googles EH zram implementation causing the phone to crash at the moment. Tried to debug this issue, but no luck for the May release here.
If you previously enabled the feature without adjusting the parameters properly and your phone didn´t crash, DAMON-Reclaim just didn´t do anything.
2.4.0 also has an updated anykernel3.zip, which includes all the latest anykernel3 changes.
Thanks to @capntrips we now have full support to resize vendor_dlkm partition which is part of the super partition. That means we finally can flash larger than stock vendor_dlkm partitions via anykernel3.zips and resize the partition properly instead of just dd´ing to it.
A huge thanks to @capntrips for working on this and to @osm0sis for maintaining anykernel3.
Disclaimer:
I´ll keep the warning as to preferably using magisk stable to avoid potential issues as well here in this post.
Please note that 24306 works fine for me though on non beta, stable May firmware!
Important:
Make sure you´re being rooted with magisk 24300 stable before flashing the kernel if you´re unsure. Any magisk version above 24303 might potentially lead to a reboot back to bootloader since android 12.1.0 and A12L QPR3 Beta. At the moment this only affects canary, but I put the warning just in case this will not get resolved in upstream magisk in time until the next stable drops. I saw a post that some modules also have problems with latest canary, so there´s a lot going on at magisk´s side at the moment.
A post containing a short write-up how to "downgrade" magisk can be found following this link.
If you´re one of the unfortunate ones that suffer from the device is corrupt bug on pixel 6 series please take a look at the FAQ at the beginning of this thread it contains a solution. The issue is probably caused by a bug that affects pixel 6 devices and has nothing to do with magisk or a kernel, it just happens to get triggered when using any of those.

Hey guys and girls,
Alright here´s the next update. It´s a major one. I want to put it out shortly before we hopefully receive the next monthly security update on Monday kinda as a final rehearsal.
This kernel is made for stable Android 12.1.0 April firmware. Not QPR Beta or A13 Beta!
Once I find enough time or QPR beta gets updated, I might update the QPR beta release. No plans to support A13 beta.
A few changes from A13 Beta are merged to the kernel so we can enjoy the improvements on A12 already. Most of them aim to improve the scheduler and task placement.

DAMON patch-series is included to this release as it was merged to kernel/common. It includes DAMON-reclaim. You can read more about it here.
This feature is currently disabled by default on this kernel. If you want to use it you can tune it to your liking as per the documentation linked above.
The feature can be enabled via:
I think Google might start to use it in the not so far future, but for now it´s disabled by default.Code:echo 1 > /sys/module/damon_reclaim/parameters/enabled

If you like my work and want to buy me a coffee/green tea: http://paypal.me/freak0725May update is out.
no source update pushed from google yet. I guess it´ll happen in a few hours when I´ll be asleep.
I went ahead and flashed the latest release for stable 12.1.0 without any issues so far.
If you can´t wait, it should be fine to flash based on that short experience.
If you want to be absolutely sure there will be no issues due to incompatible source/firmware, I´ll try to update the kernel with any new potential changes in the source for May as soon as I find time, which will hopefully/probably be tomorrow if everything goes as expected.
I wish everybody a great day/evening.19
Managed to reproduce the issue. It´s a magisk issue that surfaces probably since 2.0.1 where direct USB access was added and was not kernel related.
To get direct USB access working a firmware file in vendor/firmware is replaced during bootup when my kernel is flashed, which is required for the kernel changes to actually work.
The denylist trick to hide modifications stumbles upon that dir and fails due to a selinux error as denylist is not allowed to access that dir.
As a workaround I fixed that selinux denial and root is no longer being detected by the app.

After flashing the updated zip what I did was hide the magisk app in magisk manager, enable deny list and added the app to the list. Wipe data of the banking app, reboot (not sure if needed but rebooting is always good in these cases) and root was no longer detected by the app.
Attached are zips which include the fix the selinux denial for you to confirm.
This might also fix root detection by other banking apps that are not detecting root on stock kernel, but were broken after flashing the few last releases of this kernel.11A12L QPR Beta Kernel
For those on the A12L QPR Beta 3 here are zips to try. They are only supposed to be flashed on Android 12 QPR Beta!
They should work fine on QPR Beta 3 as source was pushed already, merged and I have confirmation it´s working fine on Beta 3.
That kernel has feature parity with the 2.4.0. So for a detailed changelog please refer to the release post of 2.4.0.
I don´t know what´s the current situation with magisk and flashing kernels on QPR Beta, but it´s probably best to use magisk stable if you don´t want to face issues. (although I have confirmation magisk canary 24307 works fine with verity/verification disabled, don´t know about vbmeta enabled)
I´m not myself on QPR Beta so please leave feedback, but remember:
These zips are provided as is I don´t have time to flash between stable and QPR
Feel free to report issues with proper bug reports (containing logs, steps to reproduce according to the guide linked in the FAQ), but they might remain unresolved if it´s not easy to fix without running A12L Beta on my own end.
I wish everybody a great weekend!
Have fun, enjoy the kernel and your phone.

98Kirisakura-Kernel for the Pixel 6/Pro
Hello everyone,
To keep it short: Here is Kirisakura - Kernel for the Google Pixel 6 Pro aka Raven and the Pixel 6 aka Oriole, together Raviole.
I would appreciate if everybody that flashes the kernel, reads at least once through this opening post and the following ones.
The kernel aims to keep most of the subsystems updated, way ahead of the stock kernel, thereby improving security, stability and performance!
This includes Linux-Stable, F2FS-Stable and kernel/common!
If that 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.
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!
Features:
Main Features:
- Based on latest kernel sources from Google, Kernel is made for Android 12
- Linux-Stable-Upstream included to 5.10.113
- Compiled with prebuilt Google clang 14.0.5

Android 12L QPR Beta
Build for Android 12 QPR Beta: https://forum.xda-developers.com/t/...pixel-6-pro-aka-raviole.4358435/post-86857033
Requirements
- unlocked Bootloader
- USB-Debugging in developer options enabled
- latest adb and fastboot binaries
- working adb and fastboot environment so you can flash back to stock in case something goes wrong
- working magisk environment (a device rooted with latest magisk stable in case you want to be absolutely safe, magisk 24303 and higher will bootloop on QPR beta and might act up on stable A12.1.0 too!)
How to flash the Kernel:
1a. Make sure you tick all the requirements above
1. Download the correct kernel.zip depending on your device (Pixel 6 = oriole || Pixel 6 Pro = raven)
(if you´re for whatever reason on November firmware -> use 1.3.0! More recent kernel releases will bootloop)
2. Flash the correct kernel.zip via EXKM or FKM. Root will be preserved. The AK3 magisk helper module will be automatically installed during flashing the kernel.zip and be present on next reboot.
Do not remove or disable the AK3 Magisk Helper Module otherwise the device will bootloop.
3. Reboot and profit.
Manual installation without relying on paid apps like fkm/exkm:

Source Code: https://github.com/freak07/Kirisakura_Raviole37Update to 1.8.4
Hey guys and girls,
So here´s the next update. It´s kind of an off schedule update, as I planned to update the kernel with the next security update/feature drop.
But in the light of recent events regarding the new exploit called "Dirty Pipe" (more info here), which is similar to the "Dirty Cow" exploit from a while ago, but easier to exploit this time, I decided to release an update ahead of schedule.
This exploit was fixed in linux-stable 5.10.102, as opposed to a single commit in AKC (android kernel common, commit here). This shows once more why merging linux-stable is beneficial as explained in detail in the OP.
Since one of the key aspects of this kernel is security and staying on par with upstream (which often fixes exploits way ahead of android security bulletin updates, even before an exploit is even known or fixed via a patch on the security bulletin) I decided to release this update as quickly as possible, so this exploit is fixed on devices running this kernel.
Several other notable improvements and changes in this release:
Bring in scheduler updates from Android 13 Developer Preview, which aim at improving task placement. (adjust powerhal accordingly)
BFQ IO-Sched is now on par with linux-mainline.
Several fixes to mm subsystem, f2fs and others.
Several other improvements are included as well. More details in the changelog.
Download is below.

Hey guys and girls,
So here´s the next update. It includes the february security update. Most of the changes brought by the February kernel source drop, were already included in this kernel by merging kernel/common and linux-stable.
Several other notable improvements and changes in this release:
Improve f2fs performance by merging a patchset to prevent writer starvation for the checkpoint thread. This was discussed this month in the f2fs mailing list and is already merged to the kernel/common tree. It´ll improve performance under heavy I/O utilization.
You can find more information following the discussion here.
Necessary backports were brought to the kernel and the platform specific f2fs-implementation was also adjusted.
Latest f2fs-stable was also merged to the kernel.
Update the patchset to prevent frequency spikes caused by small tasks as well. Tie those new changes into the powerhal. (That means users not flashing the kernel.zip, but instead use the manual installation method, which are only a handful from the download count, need to flash the updated magisk helper module. Users that flash the kernel.zip via FKM/EXKM have to just flash and forget)
Several other improvements are included as well. More details in the changelog.
Download is below.

Hey guys and girls,
Alright here´s the next update. And it´s again a really big update!
A few weeks ago google pushed a backport of Multi-Gen LRU for the 5.15 kernel to their aosp/kernel common branches. I went ahead and backported that to our 5.10 tree alongside other mm-improvements from linux-mainline. By now google pushed their own backport for 5.10, but I decided to go with my original implementation as it contains a lot more improvements alongside the main Multi-Gen LRU backport and ran stable for well over 3 weeks.
Powerhal was adjusted quite significantly too. CPU-freqs are restricted to 1.1GHZ max during screen off/device idle operations to save more power. App launches and camera operation are improved as well in the powerhal. General usage benefits from those changes too.
Latest linux-stable, f2fs-stable and kernel/common were merged as well.
Users that decide to not use the CleanSlate features and don´t install the apps won´t see the kernel parsing for the config files extensively.
Vibration Booster from CleanSlate was improved as well to kind of counter the weaker haptic feedback since the March update. Please check the linked thread from the changelog. Huge thanks to @tbalden for this. If you want to give a little bit back consider purchasing the apps via playstore or maybe a small donation.
I´ll keep the warning as to preferably using magisk stable to avoid potential issues as well here in this post.
Please note that 24305 works fine for me though on non beta, stable April firmware!
Important:
Make sure you´re being rooted with magisk 24300 stable before flashing the kernel if you´re unsure. Any magisk version above 24303 might potentially lead to a reboot back to bootloader since android 12.1.0 and A12L QPR3 Beta. At the moment this only affects canary, but I put the warning just in case this will not get resolved in upstream magisk in time until the next stable drops. I saw a post that some modules also have problems with latest canary, so there´s a lot going on at magisk´s side at the moment.
A post containing a short write-up how to "downgrade" magisk can be found following this link.
Changelog:
- Update for April Source
- Linux-stable merged to 5.10.109
- f2fs-stable merged
- fixes and improvements from kernel/common including several subsystems
- multi-gen LRU ( more info here, here as well and here)
- general LRU improvements from Linux-Mainline
- improve camera performance by tuning the powerhal during recording
- improve app launches via powerhal
- restrict maximum CPU-Freqs during screen off/ idle to 1.1GHZ for all clusters to save power
- remove cleanslate config files getting parsed excessively even if user did not install the CleanSlate apps
- improve vibration boosting feature in CleanSlate config app to allow stronger vibration again(please have a look at this post )
- other fixes for CleanSlate features such as sweep to sleep
- updated anykernel 3 zip, thanks to @osm0sis
- probably a lot more I forgot as time is short for me.

Hey guys and girls,
Alright here´s the next update and it´s fine to flash on May firmware. As I suspected we already had all the changes for May by merging upstream.
I´ll include the changelog from 2.3.0 as well in this release post, since I think a lot of people flash the kernel on a monthly basis when the security updates drop. So this post pictures the changes going from 2.1.0 to 2.3.0! As I said 2.3.0 was kind of a final rehearsal to make sure everything is good for the May update.
I´ll put a remark behind changes going from 2.3.0 to 2.4.0.
This release is made for stable Android 12.1.0 May firmware. Not QPR Beta or A13 Beta!
Once I find enough time or QPR beta gets updated, I might update the QPR beta release. No plans to support A13 beta.
I also finished up the tables/graphs in regards to different binnings with the respective voltages on different tensor chips thanks to the dmesgs you all provided. I really want to put out a big thanks here to everyone for taking the time and participating. It was really great to see this kind of response.
I´ll provide them in a post in this thread soon.
So with that in mind we´ll get to the next paragraph were I could put those tables to good use.
A few changes from A13 Beta are merged to the kernel so we can enjoy the improvements on A12 ahead of time. Most of them aim to improve the scheduler and task placement.
However the recently dropped A13 Beta source contains a commit that can restrict max-cpufreqs based on PMU (Power monitor unit) reading. I setup this mechanism (lets call it "PMU Limiter") to mildly cut back max-freqs when they aren´t needed. It works quite well so far, with no performance impacts during scenarios where max cpufreq is beneficial. (e.g. app launching, camera launching, interaction etcetc)
That means if a certain threshold is not crossed the max-freqs will be restricted to 1,4GHZ/1,6GHZ/2,4GHZ (for little/mid/big cores). As soon as the PMU detects enough pressure, those limits will be lifted.
The frequency limits are based on tracing during various scenarios, benchmarking and also factor in the voltage table I was able to create. For example: 2.4GHZ for the big cores is the last freq step where a steady linear increase in voltage can be seen. Freq steps higher than 2,4ghz have a steeper slope.
Keep in mind CPU-Freqs shouldn´t be touched in EXKM/FKM or other kernel managers. They are controlled by various mechanisms now (thermal hal, powerhal, pmu limiter etc) and values will get overwritten based on input.
That means if you open the CPU section in a kernel manager, the maxfreqs will not be the actual maxfreqs that are possible. or the minfreqs might be raised. That´s normal and there´s nothing wrong if that´s the case.
Additionally to the previous changes tasks of rt, sf and ta groups are now biased to start on high capacity CPUs during app launches, interactions etc.
As usual, depending on your usage you may or may not notice a difference during these scenarios.
While tracing I noticed kswapd often takes 100% cpu share when reclamation is happening. Since we use an 8 core cpu, an additional kswapd thread is being spawned during boot, which increases throughput for kswapd in these scenarios. Reasoning behind this can be found here.
The trusty driver which connects to the fingerprintreader hal uses now a high prio workqueue when the phone is unlocked via fingerprint scanner. This means better performance, especially under stress. Keep in mind this is a kernel level change, it won´t magically improve fingerprint reader times manifold.
DAMON and DAMON-Reclaim were removed from 2.3.0 going to 2.4.0. I tested the feature privately and it unfortunately collides with googles EH zram implementation causing the phone to crash at the moment. Tried to debug this issue, but no luck for the May release here.
If you previously enabled the feature without adjusting the parameters properly and your phone didn´t crash, DAMON-Reclaim just didn´t do anything.
2.4.0 also has an updated anykernel3.zip, which includes all the latest anykernel3 changes.
Thanks to @capntrips we now have full support to resize vendor_dlkm partition which is part of the super partition. That means we finally can flash larger than stock vendor_dlkm partitions via anykernel3.zips and resize the partition properly instead of just dd´ing to it.
A huge thanks to @capntrips for working on this and to @osm0sis for maintaining anykernel3.
Disclaimer:
I´ll keep the warning as to preferably using magisk stable to avoid potential issues as well here in this post.
Please note that 24306 works fine for me though on non beta, stable May firmware!
Important:
Make sure you´re being rooted with magisk 24300 stable before flashing the kernel if you´re unsure. Any magisk version above 24303 might potentially lead to a reboot back to bootloader since android 12.1.0 and A12L QPR3 Beta.

A post containing a short write-up how to "downgrade" magisk can be found following this link.
If you´re one of the unfortunate ones that suffer from the device is corrupt bug on pixel 6 series please take a look at the FAQ at the beginning of this thread it contains a solution. The issue is probably caused by a bug that affects pixel 6 devices and has nothing to do with magisk or a kernel, it just happens to get triggered when using any of those.
Changelog:
- Linux-stable merged to 5.10.113
- Use prebuilt Google Clang 14.0.5 for compilation
- Utilize an additional kswapd thread to increase throughput for memory reclaim
