Development [Kernel][21.03.2023][Android 13.0.0]Kirisakura 1.0.0_Raviantah for Pixel 6/Pro aka "RAVIOLE"
- Thread starter Freak07
- Start date
Don't i remember seeing you post on the pixel 7 forums?
In case you just mixed up the threads:
It's not a requirement for pixel 6 devices, it is a requirement for pixel 7 devices.
Just flashed stock A13 on pixel 6 then rooted and patched with Magisk and flash Kernel. All is working great but I can't pass safety net anyone know a easy fix?

Flash the the Universal Safetynet module from this thread.

Thread '[GUIDE] Pixel 6 "oriole": Unlock Bootloader, Update, Root, Pass SafetyNet' https://forum.xda-developers.com/t/...ootloader-update-root-pass-safetynet.4356233/
The only way to keep root is to flash the stock rom's patched boot.img (yes it works)
I doubt that would happen...
That's sad, can't even use a USB wifi dongle on P6P.
Can you please enable the DisplayPort function USB-C DisplayPort video output DP Alt Mode ?

Even if support for the usb c out "alone" would be added, the display driver needs to be adjusted as well. If support can be added there without proper documentation of the panel and ddic we get to the bigger problem: the firmware of the panel needs to support it as well, just like on pixel 4/pixel 5.
Additionally USB connections go through the AOC driver on Pixel 6/7. That driver is also paired with a special firmware on vendor partition, that needs to match the kernel driver exactly.
If anyone knows how to do all that (especially the part about reverse engineering the firmware, hals etc) it might be possible.
Hm who better than to ask you... So many Pixel devices and such good development. I'm sure you know about the infamous un-fixable ARB Brick on the Pixel 6, 6 Pro, 6a, 7, and 7 Pro... I've been doing some hard research and I finally figured out what the phones are asking for upon initial connection. URB (USB Request Block) is the baseline for the Pixel ROM Recovery. It's basically the same thing that was used to create the HSUSB Qualcomm 9008 device drivers with the exception that it's definitely branded differently. I know this may not be your cup of tea, but as you seem to know how Google's Build System works more than I I was wondering if you wouldn't mind giving me a hand. My DM's are open and you're definitely more than welcome to decline. I'm just so close to solving this but I could use someone else to help with this too. Thanks in advance. Oh and sorry for the thread hijack...
Important
Just a heads up for everyone:
If the firmware update that's going to drop most likely today contains the QPR (=quarterly platform release, so the changes currently tested in the QPR A13 Beta) amongst the pixel feature drop, don't flash the current release of the kernel until I update the kernel with the new sources!
Otherwise there might be issues or the device refuses to boot due to the new firmware requiring the necessary kernel changes as well!
I'll try to update as fast as possible, but depending on how much conflicts there are and how fast google pushes the new source, merging the new source it might take a bit.

verity disable do need to wipe before disabling right if not mistaken, Im using this kernel with verity enable since day one. Dont quite have the time to wipe and setup everything. So can I continue to use this kernel like before?
Where exactly to we must disable verity/verification flag in the process? Or is it only relevant for someone who wants to flash the kernel first time? I’m not sure I’ve done it when I started to use this kernel. I used to update like shown below and just flash the kernel afterwards:
- Use the latest Magisk Stable (in my case, I keep the app "hidden" / renamed)
- Used the full firmware zip, extracted to the same folder as the latest Platform Tools (S:\platform-tools)
- Extracted the new boot.img
- Copied new boot.img to the phone
- Patched the new boot.img with Magisk Stable
- Renamed Magisk'd boot.img so I know what version of firmware it's for
- Copied the Magisk'd boot.img back to the computer
- Disabled all my Magisk Modules
- Removed the "-w " from the flash-all.bat
- Re-edited the flash-all.bat to verify I saved it with the "-w " taken out
- Open a Command Prompt, navigated to S:\platform-tools
- adb reboot bootloader
- flash-all.bat
- Let phone boot, unlock it, check that it's working, allow the update process to finish (gave it five minutes or so)
- adb reboot bootloader
- fastboot flash boot kernel.img (renamed Magisk'd boot.img)
- fastboot reboot
- Unlock, check everything's working
- Re-enabled the most basic Magisk Modules which I was sure wouldn't cause a critical issue
- Reboot, unlock, made sure everything's working
I'm using a P6P and have never had to do this. I just flash with EXKM.
exactly the same hereI'm using a P6P and have never had to do this. I just flash with EXKM.

34Update to Raviantha 1.0.0
Hey guys and girls,
So here´s the next release for stable March firmware, which is now QPR2 based. This results in quite a lot of changes and improvements in the vendor specific drivers!
Aside from that as already hinted at in the Pixel 7/Pro release for March google kind of unified the main kernel tree for the Pixel 6 and Pixel 7 series. That means I´m now able to compile the release for Pixel 6 and Pixel 7 from the same main kernel tree after some modifications to my own changes! This saves me a bit of time and means all not vendor/firmware/hardware specific improvements added to the kernel are now shared automatically, without me constantly merging them back and forth.
Hence the name change and starting from 1.0.0 again. Pixel 6 Oriole/Pixel 6 Pro Raven combined are Raviole, Pixel 7 Panther/Pixel 7 Pro Cheetah combined are Pantah, so Raviantha is the combination of both Raviole and Pantah.
Please note there are still separate zips due to the powerhal being different and the ramdisk in vendor_boot not being exactly identical.
As part of this development all improvements from the linked pixel 7 release found its way into this release plus a few more. So this time you guys are the first.
Short explanation follows below.
Please note that this release is not for the QPR Beta firmware, but the stable android 13 march firmware!
Please make sure to not use magisk canary 25210. It breaks module loading and causes a lot of issues! Please use either stable canary or canary 25206.
Latest platform tools have issues flashing super.img, please use platform tools 33.0.3!
Maple Tree / Per VMA-locks via Maple Tree in RCU-Mode
Updated this patchset to a new refined version that´s currently been tested.
Bit of a graph that shows app launch times with and without this patchset:
Link to the graph can be found here.
Explanation of the patchset in hide tags below!
Linux 6.1 finally merged the Maple Tree patchset. I had my eyes on that patchset for quite a while now. I backported it a few months ago (back in november iirc) but at that time I still ran into a few problems with it so it never made it into a release on XDA.
However after discovering work done on per vma-locks, which builds directly on the benefits that maple-tree provides interest was sparked again. Decided to pull it in again and fix the remaining issues.
If you´re interested in details read the linked topics.
Basically those patches reduce app launch time as well as lock contention. Additionally per vma-locks directly utilizes lazy-rcu, which was backported in 1.1.0. Usually I´m very hesitant when it comes to kernel changes actually translating to real world power consumption improvements, but lazy-rcu is one of the few patchsets that translate to a small improvement for everyone regardless of the usage.
So the new per VMA-lock patchset directly benefits from the previous backport of lazy-rcu.
Improve Uclamp
Improve uclamp patchset and detect capacity inversion. This greatly reduces the few missed frames we had.
Camera Launch Speed
Speed Up Camera launch by quite a bit. Also improve animations around camera compared to stock kernel.
There are other small improvements as well. Please check my github for those.
The kernel is made for stable A13 firmware, not beta.
I wish everyone a nice day.
Changelog:
- Linux-Stable bumped to 5.10.175 containing tons of stability and security fixes
- kernel is now built with latest clang 17.0.0 prebuilt from google
- Update Per VMA-locks patchset from previous release (this benefits greatly from lazy rcu!)
- improvements to MGLRU
- bump f2fs to latest f2f2 stable state
- improvements to the scheduler
- improvements to uclamp, prevent capacity inversion (reduce missed frames)
- greatly speed up camera launch time!
- ported improvements from QPR3 beta
- fixes/improvements to to memory management
- security fixes/ improvements from kernel/common
- optimize code around nr_cpus from latest linux
- other fixes please check github

Attached to release post as AFH is currently down.
Make sure to not delete and keep the powerhint ak3 module installed via Magisk Manager after flashing!
If you´re coming from another kernel restore stock boot.img, dtbo.img, vendor_boot.img and vendor_dlkm.img before flashing or simply dirty flash. Thank you.
Make sure to meet the requirements and read the OP as well as the FAQ before flashing.
I wish everybody a great day/evening!
Have fun, enjoy the kernel and your phone.

Yes, cpu is only one source of heat.
As you already pointed out modem is another one, just like the camera array itself will produce heat while using it (especially noticeable while taking videos, which presents two issues, if cpu is throttled to much hi-res video might produce stutter, if heat is not kept in check camera sensors might get damaged).
If you want to take a look at the thermal throttling you can find this on the device tree. This one is for p6 pro (raven).
Release for January firmware is attached to the release post for january, you can find those in the OP.
Thanks a lot for taking the time and actually posting logs!
That issue is the same I replied to in this post and will be fixed on the next release.4
not really
Were you using Youtube vanced and a corresponding magisk module? I suppose the hot reboot might kill the overlay somehow.
But as stated here, it’s not really kernel related so I guess we won’t be able to fix it anyway if its some firmware/framework related issue.
For losing the app, if it’s indeed vanced you’re using a logcat in that thread or on github might be the best way.4 -
120Kirisakura-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:

Android 12L QPR Beta - Deprecated
Build for Android 12 QPR Beta: https://forum.xda-developers.com/t/...pixel-6-pro-aka-raviole.4358435/post-86857033
Requirements
- the kernel is made for the stock firmware provided by Google, pay attention to flash a kernel release matching the firmware (flashing on custom roms might work, but you may need workarounds!)
- 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)
- IMPORTANT: Unrelated to the kernel, but update both slots of your phone to A13! (take a look here)
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)
2. Flash the correct kernel.zip via EXKM, FKM or kernel flasher. 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 is no longer supported starting with release 3.0.0, as there´s a free open-source option to flash kernel.zips now.
Instead use the free kernel flasher, which can be found here.
Manual installation without relying on paid apps like fkm/exkm:

Source Code: https://github.com/freak0744Update to 4.1.0
Hey guys and girls,
I hope everyone started into a good week. Here´s the next release. It´s for stable Android 13.
Thanks to Google releasing the kernel source for the previews and the betas I´m able to push this update out very quickly. As in the past, the code didn´t change between last beta and stable release.
There are again a lot of changes in this release. I´ll try to keep the release post short as I don´t have that much time lately.
FHD/1080P Support for Pixel 6 Pro
The biggest change is FHD support for the Pixel 6 Pro. If you follow twitter you might have seen this tweet from @MishaalRahman.
Instead of using the display driver that´s supposedly for the Pixel 7 Pro, FHD support was added to the Pixel 6 Pro display driver. There were a few obstacles to make it run properly on the Pixel 6 Pro, but I got it working nicely so far. If anyone has more experience than me regarding panel timings, display drivers etc, feel free to push any improvement as a pull request to my github or point me towards any improvement.
As a result you can now select 1080p resolution from settings after flashing the kernel. Dynamic refresh rate works, brightness scaling works, no tints, colour shifts or contrast issues either. AOD has a 1080p Low-Power timing as well.
You´ll find a few more infos with a short video on my tweet here:
It´s perfectly usable on a daily basis so far. I ran it for a few days without issues on my end. While the advantage might be debatable (saving battery, less load on GPU, still needing to drive the same amount of pixels in the end even on lower resolution, etc etc) having options is nice and this is why I decided to ship it.
Apps need to redraw after switching resolution, sometimes 1080p on big display size selected in settings the UI looks a bit sketchy. So I think Google is still working on that.
There´s however one bug I found so far that makes me believe this is still very much a WIP from google. If having the "show current refresh rate" option from dev settings enabled while switching resolutions, the display will black out and a restart needs to be forced by keeping the power button pressed or using adb interface to restart the phone. This is not due to the kernel, but display settings in framework getting scrambled as it´s not yet implemented 100% on googles end. So be warned.
MM Subsystem Rework
MM subsystem was completely reworked including many improvements from linux-mainline. During this MGLRU was also reworked a bit and works better now. I´ll include links to a few of the improvements/patchsets in hide-tags below, if you´re interested beyond that please check out my github.
links:
Additionally tie in a few of the MM changes into the powerhal. For example Proactive compaction is more aggressive during screen-off/device suspended operations to improve long term-performance.
Other changes:
Also tune the powerhal and implement all A13 changes, according to the changes that were already present on A12.
Latest changes from f2fs-stable are included, which include several bugfixes and small improvements.
Binder improvments/fixes, scheduler improvements from kernel/common, performance for exfat formatted storage device improved (niche use case, but still nice) and other little improvements.
For other changes and details please take a look at github.
I wish everyone a nice day.
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:
- Rebase kernel fully on A13 trees
- Linux-Stable bumped to 5.10.136
- FHD/1080p support for Pixel 6 Pro
- all previous features and improvements kept intact
- bump f2fs-stable to latest available
- rework mm subsystem (check git for more details)
- scheduler improvements
- binder improvements from kernel/common
- improve exfat performance (if someones uses exfat formatted devices)
- loads of other changes from kernel/common
- update powerhal to account for a13 changes and port existing changes over
- loads of other changes, please check github

Hey guys and girls,
I hope everyone started well in the new week. Here´s the next release and it´s a rather big one with lots of under the hood improvements.
We already had all the changes in from the October security patch release released, due to merging linux-stable stable and kernel/common in advance.
The kernel is now at 5.10.146 way ahead of the stock kernel. To further emphasize the importance of this. About 90% of kernel security issues are solved in linux stable. While I didn´t check the actual number myself, I´d have estimated about the same (80-90%) before actually reading the slides from @arter97 presentation.
What also needs to be kept in mind is that a big part of those security issues are resolved in linux-stable sometimes months ago before those patches end up in a monthly security patch. Additionally to that the security patches are about 3 months behind the discovery of those vulnerabilities.
Amongst linux-stable upstream there are a few other not minor updates in this kernel.
Clang
The kernel is now compiled with the latest prebuilt Clang from Google. This was quite a journey as this is a pretty big update to clang. This is quite experimental to be on googles side of a "bleeding" edge compiler, but after fixing several issues that originated from the new compiler it ran stable for over 2 weeks.
There´s a potential for CFI failures that originates from that new Clang rather than a "real attack", due to the changes in clang.
Short reminder what CFI actually does: Control flow integrity (CFI) is a security mechanism that disallows changes to the original control flow graph of a compiled binary, making it significantly harder to perform such attacks.
A typical crash (that´s not wanted and originates from compiler changes rather than an actual attack, which is already resolved of course ) would look like the following: Open camera app, due to compiler changes CFI is accidentally tripped every time this code is executed.
I think we catched all of these newly CFI failures and everything is nice and stable. In case you discover such a behaviour please send me the contents of sys/fs/pstore, once the phone booted back up.
There´s always the possibility of a "real" attack in which CFI will crash the phone, before the attacker can compromise the phone. That´s why keeping subsystems updated is important.
Powerhal
The powerhal was retuned due to changes to the scheduler introduced. It should work even better now, regarding efficiency and performance. Of course I try to tune it also to my personal needs, while trying to keep it working for all workloads. The changes are not drastic, so please don´t post after several hours you see drastic differences.
Other improvements
Several other improvements from kernel/common (for higher branches than 5.10) and linux-main were backported to this branch so we can benefit from those improvements. For details please check my git.
I´d like to write all of this with more detail, but at the moment I lack the time to do so.
Kernel is compiled for stable A13, not A13 QPR Beta!
I wish everyone a nice day.

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.
