Development [Kernel][06.03.2024][Android 14.0.0]Kirisakura 2.2.0_Raviantah for Pixel 6/Pro aka "RAVIOLE"
- Thread starter Freak07
- Start date
Sorry, yes, completely stock. I actually replaced one 6 pro thinking it was caused by a bigger problem.
Thanks for the quick reply. I've tested it multiple times, even on fresh install. It's been stuck on this loading screen for roughly 5 minutes now. Seems to do it after you restart multiple times back-to-back. I'm going to see if I can replicate it consistently. I'm curious if other users are experiencing the same thing?
Yes, it should work just fine. Use either the latest kernel.zip or if you follow the manual route make sure to patch the provided boot.img with latest magisk canary.
However there seem to be quite a few users running into issues with verity on this forum and device. Not only when flashing kernels, but also in the guide threads. If you´re a bit unsure I´d only flash it if you have a PC nearby to flash a factory image to be able to recover and have a backup of your data ready.
If it´s stuck for 5 minutes something else is wrong and it´s not due to the factors I mentioned earlier. I haven´t run into this issue at all, so something else might be screwed up if that happens regularly.
Just tried 6 consecutive reboots and everything is working just fine.

I've factory reset and so far I've only seen it once now. I'll post again if it continues to do it. However, I think it's working well now. Thanks again.
thanks for the reply. I have tried it and got the same issue mentioned here, that's weird
Is it possible to implement dt2w feature at kernel side? I don't think that single tap to wake, which is default on Pixel, is right solution.
This kernel is working really well for me. Battery life is excellent, the phone is responsive and runs smooth.
I'm looking forward to the next release.
Thanks @Freak07 for all your work. It's appreciated

Food for thought any idea about the charging limiting
The pixel could do a 1hour charge if the limit didn't kick in halfway

Yes, to fix for me on standard firmware was to disable Adaptive battery under battery settings, never saw the issue again after this. definitely haven't seen it with this Kernel even with that enabled.
What made you leave proton to come back on Pixel release? Bro? Isn't proton technically better performance and battery life?
I never had issues with stock, and still don't.
I just wanted to try ProtonAOSP out. It was a little quicker at opening apps, but not enough built in customization for me, plus I had an email bug with it that caused me to have to open emails twice to read them.
I'll wait for crDroid instead.
Are you guys having complete loss of touch until you turn the screen off and back on and touch is restored?

Same on my end. I could reproduce similar results on pixel 6,7 and 8 pro.
There are next to no changes on the wifi driver on my kernel.
Maybe it's just an "issue" in that specific scenario though and not while gaming or when ping matters more.21
Yes, I have a a similar variation.
Don't know if it's kernel related though. Would have to wait until next monthly update (next week) to check out with the stock kernel.1
all fine on my end.
the kernel has no impact on displaying this information.
It´s related to play services, google services, google app and the launcher, location services etc.
If you use mods/magisk modules that alter this in any way, that´s were this can break.
The kernel would only break mobile data, wifi or similar, but for the entire system/all apps/services. -
127Kirisakura-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!

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:
Please have a look at the linked post.

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.
Updated instructions in the OP!

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.
