thanks for your hard work and commitment!
- vbmeta flags for verity/verification disabled (this requires a wipe if you´re coming from stock with those flags enabled), check the FAQ for information on how to do this- vbmeta flags for verity/verification disabled (this requires a wipe if you´re coming from stock with those flags enabled), check the FAQ for information on how to do this
Did you do this?
and when you updated to the Feb patch did you make sure the flags for verity and veritification were still disabled?
1.2.4 Installed. Definitely feel like there is less UI jank and overall improved responsiveness. Thank you @Freak07

In order to run custom kernels, you need to set them flags on EVERY update.
Yeah known issue....
After rebooting specifiek apps loosing permissions..( behaving same as you just installed them)

owh I thought it is a feature? https://developer.android.com/about/versions/11/privacy/permissions#auto-reset
Just to clarify as this may sound a bit ambiguous : This is not a kernel issue or related to the kernel.
Thanks for the link!
no, flash the kernel and forget. Most settings will not stick.

I ended up flashing that newest B1 build and Kirisakura. Things seem OK so far.Most probably yes. There's no source update as far as I can see.

15Update to Raviantha 2.2.1
Hey guys and girls,
Here´s a kernel that fixes the crashes during booting that some seem to experience quite regularly while others not since the March update.
It´s due to the timing and order of modules being loaded on this kernel vs the stock kernel. Thanks to @Sultanxda´s work we do no longer need to disable the vbmeta flags, because all drivers are built into the zImage and we don´t need to touch vendor_dlkm. This seems to slightly alter the timing/order of the boot process. The issue does not happen on stock, because that issue in the code is "masked" by the kernel being built in a modularized way on the stock kernel.
However something in the March firmware changed the boot process and triggered this bug now regularly if the kernel is built as a single zImage with all drivers being built into that. Thanks to @Sultanxda for sharing the fix for this issue with me!
I´ll keep this post and the changelog short because I don´t have much time.
Since the powerhint module is now unified it makes sense to include it to the kernel.zip. This means there´s no separate zip to flash any longer. After flashing the kernel.zip you´ll see a module called AK3 Helper Module in Magisk Manager. Do not delete this module, it´s crucial for the device to boot/work!
This means if you want to switch kernels, go back to stock kernel or dirty/flash a new firmware be sure to remove the AK3 Helper Module in Magisk Manager before restoring or flashing another kernel or firmware!
I also adjusted the FAQ! You have been warned.
Important:
Please note that this release is not for the QPR Beta firmware or dev preview, but the stable android 14 firmware!
Please make use magisk stable if you don´t know your way around bugs and don´t want to actively help debugging magisk development.
You should download magisk stable only from official magisk release site!
There are other small improvements as well. Please check my github for those.
The kernel is made for stable A14 firmware, not beta.
I wish everyone a nice day.
Changelog:
- Fix reboots during bootup that started happening since March update.
Download:
Attached to release post as AFH is currently down.
Delete the old powerhint module in Magisk Manager before flashing the new one as the Module ID changes!
If you´re coming from another kernel restore stock boot.img, dtbo.img, vendor_kernel_boot.img and vendor_dlkm.img before flashing. 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.

First, always read the OP of a thread before asking any questions.
From the OP
- this kernel is tested on stock google firmware. If you want to use it on custom roms you´re kind of on your own as I can´t account and give support for any changes custom roms apply that could render the kernel incompatible. (e.g. if you´re custom rom is still on the previous months update, there may be issues flashing an updated kernel for the next month on top or custom roms requiring specific kernel changes to work correctly )2

Why would you not use the release he literally said was fine for April? And if he was to release a new one, why can't you install that on top of 2.2.1? -
92Kirisakura-Kernel for the Pixel 7/Pro
Hello everyone,
To keep it short: Here is Kirisakura - Kernel for the Google Pixel 7 Pro aka Cheetah and the Pixel 7 aka Panther, together Pantah.
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.
By merging linux-stable regularly we get most security updates months ahead of the stock kernel and also before they even end up in the android security bulletin.
The kernel includes a lot of improvements and contributions from other developers as well. Without those contributtion this kernel would not exist as it is.
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!

- MM subsystem reworked (more info and some patchsets linked in this post)
-Multi-gen LRU backported/reworked and enabled (more info here, here as well and here) to improve mm and reduce cpu cycles, latest V15 state(current state disabled, as google remotely controls the prop)
- pelt multiplier tied into powerhal to speed up scheduler during interaction (more info here)
- prevent frequency spikes caused by small transient tasks when the device is idle(more info here)
- tie mechanism to prevent frequency spikes caused by small tasks also into powerhal
- scheduler improvements for RT (realtime) tasks
- introduce and setup PMU limiter (prevents CPU from spiking to max when it isn´t needed, based on PMU reads, more information here)
- improve camera performance by tuning the powerhal during recording
- bias tasks of rt, sf and ta groups to prefer high capacity cpus during app launches, interactions
- improve app launches via powerhal
- restrict maximum CPU-Freqs during screen off/ idle to 1.4GHZ for all clusters to save power

- include bbrv2 from google, more info here
- Enable support for TTL spoofing
- important patches from kernel/common for 5.10 (here are more details)
- increase priority of GPU work
- several updates from QPR beta, and a few from Pixel 6 that googles missed to include in the pixel 7 kernel
- improve thermals

- improve ZRAM usage
- reduce overhead
- improve performance and efficiency by properly wiring up pixel_sched with teo util awareness (thanks @ada12 for spotting this!)
- update to cpuset/cgroup subsystem (speeds up camera launches, device unlocks etc as cpusets are switched on those conditions, patches reduce overhead in those conditions)
- flashing the kernel will preserve root
CleanSlate Features
- CleanSlate Features from @tbalden, big applause here! (s2s, notification booster, battery saver, flashlight notifications. Please note: cleanslate features that work otherwise with rooted devices like kadaway (adblocking) are not implemented on this kernel since I´m running rooted)
- Check the CleanSlate thread for more information about those features
- The CleanSlate thread also contains the apps that allows you to control those features!
- If you consider those features useful, maybe consider purchasing the apps in the PlayStore or a small donation to @tbalden, he deserves it! Don´t forget to switch to beta channel for those apps, as this is needed for device running A13!
Various Optimizations:
- update several drivers to use power efficient workingqueues (for example wlan driver)
- f2fs: reduce timeout for uncongestion
- f2fs: Demote GC thread to idle scheduler class
- f2fs: set ioprio of GC kthread to idle
- tcp: enable advanced tcp, give user more options for tcp alorithm
- mm: vmstat: use power efficient workingqueues
Wakelock Blocker:
- advanced wakelock blocker with the ability to block kernel wakelocks (dangerous, use with caution, please read this for further info). You should only block kernel wakelocks in case you face uncontrollable scenarios, like company wifi causing a wakelock to be active 100% of the time! Blocking kernel wakelocks to "improve" battery life almost always backfires and causes issues!
Powerhint Module:
- restrict little cluster to 1,4ghz mid cluster to 1,4ghz and big cluster to 1,4ghz during screen off, to reduce battery usage for example during music playback
- only use little cores during screen off/device suspend
- account for scheduler and other changes done to the kernel
- boost memory interface controller during interaction (decreased missed frames, improved soc efficiency according to google docs)
- tie pelt multiplier into the powerhal (more info here)
- prevent frequency spikes caused by small transient tasks during idle operation (more info here)

- setup and control PMU limiter via powerhal (more info here)
- switch between default and custom idle energy model on device is being interacted with / device idle.
- reduce missed frames during scrolling/device interaction by adjusting uclamp boosts
- dynamically adjust target load for memory interface during interaction.
- remove dynamic GPU policy change as it´s causing instability and is unneeded due to GVFS period
- implement handling during video recording of CPU like Google did on QPR A13
- more small improvements

Requirements
- vbmeta flags for verity/verification disabled (this requires a wipe if you´re coming from stock with those flags enabled), check the FAQ for information on how to do this -> not required starting from Raviantah 2.0.0
- 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, use stable in case you want to be absolutely safe)
- IMPORTANT: Unrelated to the kernel, but update both slots of your phone to A13 before you flash anything to your device!
- it´s handy to have a backup and a way to return back to stock (check the faq for that)
- make sure to download the correct kernel version for your firmware. (you can´t flash a kernel made for stable firmware on a QPR beta or dev preview and expect there to be no isses, the release posts mention which firmware the respective kernel releases are compiled for)
- this kernel is tested on stock google firmware. If you want to use it on custom roms you´re kind of on your own as I can´t account and give support for any changes custom roms apply that could render the kernel incompatible. (e.g. if you´re custom rom is still on the previous months update, there may be issues flashing an updated kernel for the next month on top or custom roms requiring specific kernel changes to work correctly )
- it´s always best to start on stock images and don´t have another custom kernel flashed when flashing this kernel for the first time. consecutive flashes can just be installed on top, if not I´ll mention it in the release post
- read the first and second post, there's a lot of valuable information
How to flash the Kernel:
1a. Make sure you tick all the requirements above
1b. Make sure to flash the release made for your firmware! Usually the release post contains information on that
1. Download the kernel.zip (unified for both devices)and the correct powerhint module depending on your device (Pixel 7 = panther || Pixel 7 Pro = cheetah, starting from raviantah 2.0.0 the module is unified )no longer necessary since Raviantah 2.0.2
2. Flash the powerhint module via magisk manager as you would any other magisk module! Make sure to flash the latest one. It will be mentioned in the release post if there´s an update.No longer necessary since Raviantah 2.0.2
Make sure to remove all previous installed powerhint modules before flashing Raviantah 2.0.2 and later
3. Flash the kernel.zip via EXKM, FKM or kernel flasher. Root will be preserved.
4. Reboot and profit.

Source Code: https://github.com/freak0751Update to 1.2.4
Hey guys and girls,
So here´s the next release. February source did basically not contain anything new for this kernel (as all patches were already included since months due to merging linux-stable and kernel/common in advance) except a stability and a security fix for the GPU driver (which is vendor specific so of course not impacted by linux-stable etc).
Nonetheless this is a very big release with large underlying changes.
Short explanation follows below.
Please note that this release is not for the QPR Beta firmware, but the stable android 13 firmware!
Make sure to update/flash the new powerhint module attached to this post via magisk manager as it´s been updated!
Maple Tree / Per VMA-locks via Maple Tree in RCU-Mode
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.
App launch times in ms for cold launching slack app with and without the Per-VMA lock patchset:
F2FS block_age-based extent cache
Latest f2fs-stable update contained an interesting new feature called block_age-based extent cache. It´s another optimization done in hindsight to android needs. It´s always nice to see different OEMs (in this regards xiaomi) cooperating and improving android as a whole and not just keep those patches to themselves. Since it´s pushed to f2fs-stable it will sooner or later (probably rather later as trickling through until it ends up on actual production devices always takes a lot of time) find its way to the majority of android devices.
The features allows to record data block update frequency of the extent per inode, in order to provide better temperature hints for data block allocation thereby improving the accuracy for data temperature classification and reducing the garbage collection overhead after long-term data updates.
Memory Interface Controller Boosting
Boost Memory Interface Controller slightly to a fixed min_freq value during interaction, instead of relying solely on the governor taking the decision as it doesn´t ramp up fast enough during interaction in some cases.
Research of exynos/tensor characteristic shows that the SOC does not perform optimally when cpu freqs ramp up quickly (during interaction, scrolling, touch the screen) and memory interface controller not following suite quite fast enough. This makes the soc overall perform less efficient. The boost aims to correct this behavior.
The boost also results in a tiny few less missed frames during interaction as a bonus.
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 5.10.167
- Backport Maple tree from Linux 6.1
- Per VMA-locks in conjunction with Maple Tree RCU-Mode (this benefits greatly from lazy rcu!)
- bump f2fs to latest f2f2 stable state
- merge and enable f2fs block_age-based extent cache (improve the accuracy for data temperature classification, reduce the garbage collection overhead after long-term data updates)
- improvements to the scheduler from QPR2 Beta 2 and Beta 3
- improvements to memory management from QPR2 Beta 2
- improve ZRAM usage
- boost memory interface controller during interaction (decreased missed frames, improved soc efficiency according to google docs)
- import security fixes and performance improvments to camera driver from QPR2 Beta
- fixes/improvements to to memory management
- security fixes/ improvements from kernel/common
- other fixes please check github

Hey guys and girls,
So here´s the next release. As already hinted it includes some of the kernel changes from the QPR2 Beta. Please note the kernel is made for the stable firmware! You need to be on December stable firmware release to be able to install and run this kernel properly!
Make sure to flash both, the kernel.zip and the powerhint magisk module as both are updated.
Google did some significant updates in that latest qpr2 update, which is great to see.
The GPU driver is now based on version r38p1. This fixes several vulnerabilities that made the news recently.
AOC driver and WiFi driver were also updated and most of those improvements ended up in this kernel release as well.
There were several improvements to memory management done by google, which should result in improved efficiency, improved reclaim and also reduced jank.
There are a few other nice patches that should improve performance and generally improve system responsiveness. For specifics please check those on github.
Scheduler patches from linux-main are also included.
The lazy rcu patchset was updated to the latest state that was also recently merged into the linux kernel. (more info about lazy rcu check here)
Kernel is now compiled with latest 16.0.2 prebuilt Clang from Google.
There are other small improvements as well. Please check my github for those.
I wish everyone a nice day.
Changelog:
- Linux-Stable bumped to 5.10.159
- Bump prebuilt clang to latest 16.0.2 from Google
- include most of the QPR2 improvements so we can enjoy them ahead of time
- fixes/improvements to to memory management
- import all improvments from google QPR2 to powerhint module
- other fixes please check github

Hey guys and girls,
So here´s the next update. It´s for stable Android 14 and it´s a really big update. It contains a lot of the changes I worked on during the previous months and I finally feel they are ready to be pushed.
I´m short on time so here´s a brief writeup on the changes introduced.
EEVDF scheduler patches from latest linux are included. Have a read here. You can find more details here and also here. Alternatively use Google, there are a lot of resources.
I tested this for a few months now. Since it´s merged to linux, it will be properly updated and tested for regressions in case there are any. That was what finally pushed me over the edge.
The powerhint module was reworked. This results in less energy usage for various scenarious, scrolling in apps, watching videos, most games. (thereby also improves thermals within the boundaries of what's achievable on tensor/exynos ) This was achieved by "abusing" the PMU limiting feature from Google and expanding it with a switch that makes it work the opposite. The powerhint module was adjusted for all recent scheduler changes, such as EEVDF patches, scheduler updates from linux and the latest ones from 14 QPR Beta.
Lockless slab shrinker was backported as well.
There are a lot of other changes and patchsets for various subsystems, that should be mentioned as well, but I simply lack the time. For RCU, Maple tree, per-VMA locks etc etc.
You can find them on the changelog and on my git if you´re interested.
Thanks to @Sultanxda this kernel is now build in a monolithic fashion. That means all drivers are compiled into the zImage. This means no more modules and vendor_dlkm does not need to be modified any longer, which in return means users won´t have to disable the avb flags for veritiy/verification any longer to be able to boot the kernel.
However there´s something I want to keep everyone in mind. If you currently run with the flags disabled you might want to keep them disabled just like you did over the last months while updating. There´s the slight chance that kernel changes introduced by google in the future, changes to partition layout or undiscovered bugs will screw the monolithic build up. I tested it as best as I could and didn´t find any issues, but that´s just an advice I want to put out.
There are loads of other changes as well, but I don´t have enough time for a more detailed writeup.
Please make sure to delete the old module powerhint from magisk manager before flashing the new one.
Important:
Make sure to flash the powerhint module attached to this post via magisk manager if you haven´t already done so.
Please note that this release is not for the QPR Beta firmware or dev preview, but the stable android 14 firmware!
Please make use magisk stable if you don´t know your way around bugs and don´t want to actively help debugging magisk development.
You should download magisk stable only from official magisk release site!
There are other small improvements as well. Please check my github for those.
The kernel is made for stable A14 firmware, not beta.
I wish everyone a nice day.

Attached to release post as AFH is currently down.
Delete the old powerhint module in Magisk Manager before flashing the new one as the Module ID changes!
If you´re coming from another kernel restore stock boot.img, dtbo.img, vendor_kernel_boot.img and vendor_dlkm.img before flashing. 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.
