There´s nothing you have to set after flashing the kernel regarding CPU.
You can choose to enable kcal, wake gestures etc via a kernel manager though.
as far as I´m aware it should just work fine on custom roms.

Update to 4.1.0_S
Hey guys and girls,
I hope everybody started in a Happy New Year 2022. Here´s finally the next update.
Google code was merged up to January 2022. Pixel 3a still gets updates, so I merged this.
Linux-Stable was merged up to 4.9.297. This should include a lot of security related updates, that will trickle in the kernel security updates over the next months.
Other changes please check the changelog and/or github.
I wish everybody a great day.
Enjoy the device and the kernel, because I certainly do.
Special thanks to @jcmm11 and @melgar for testing and keeping up with me!

How to flash the Kernel:
1. Make sure you are rooted, are using the latest magisk suited for your OS version and a kernel manager capable of flashing a zip is installed. If available you can use TWRP as well. Download the kernel.zip to your device.
2. Flash kernel.zip via your favorite method. Kernel Managers and Recoveries need to be updated to work with a specific Android Version. It's your job to ensure compatibility! Root will be preserved! (Make sure to be on the latest firmware the kernel is made for)
3. Reboot and profit! Before reporting any issues make sure to read the first three posts of this thread!
Instructions can be found in the OP too!
Have fun, enjoy the kernel and your phone.

I have a question. I have been using your kernel for 2 days on stock firmware android 12 been dealing with some battery drain during screen off, i turn off auto sync, wifi,.gps and left on the data iand no battery saver. I left at 98 percent charged i woked up to 90 percent phone was not touch for 9hours. Here battery status with betterbatterystatus screenshot.

What's the question?
I suppose it's about losing 8% over 9 hours.
Your phone slept absolutely fine, there's no kernel wakelock that kept the phone awake. According to BBS your phone slept extremely well.
I'd try using wifi rather than mobile connection if possible overnight as it will consume less power.
Other than that it could be the device's age, an installed app, background work being done.
Oops forgot add that question lol but u answered it i noticed using data is a battery hug for sure. Thank you for ur reply.
good afternoon, does this mean that the device is losing performance? I can't disable Power saving workingqueues
hello, thanks for your work)
the question is, is it possible to update the adreno drivers to version 604 or 611? Or are they not suitable for us?

no performance loss.
power saving workingqueues is a compile time option. some kernels allow it to be changed during runtime, but it´s by design not "toggleable" as it´s a RO property.
Nothing to do with the kernel. You can try to update them, but you might run into issues.
Update to 5.0.0_S

As expected this might be the last update from Google for the Pixel 3 XL. Here´s a fresh build with the February updated for 4.9 merged.
Linux-stable was updated as well.

GPS is not handled by the kernel. @spezi77 contacted me yesterday and described what I believe is the issue you´re describing too, so I tried today to reproduce it using GMaps while driving. GPS works fine here, there´s no issue on my end using the stock rom.
I would like to explicitly point out that the GPS problem seems to only exist with the Kirisakura kernel compiled inline into the PixelDust rom. Please do not confuse this fact. There is no problem in freak07's official Kirisakura kernel. Thank you!
Yup...kernel is fine...tried it on various roms and all is well. Thanks.

It depends. Some parts of a security bulletin can be kernel side fixes.
Due to merging linux-stable to basically latest in this kernel, we´re ahead of the "official google security bulletin".
Since P3a devices still get support from google I´ll continue merging those for now, which will also include any kernel side security fixes, we won´t already have by merging linux-stable in this kernel. Generally I´d say we´re probably ahead of the official security bulletin, by having linux-stable merged to nearly latest.

94Kirisakura-Kernel for the Pixel 3 and Pixel 3 XL
Hello everyone,
To keep it short: Here is Kirisakura - Kernel for the Pixel 3 aka Blueline and the Pixel 3 XL aka Crosshatch, together Bluecross.
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!
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 focus during testing! This includes Linux-Stable, CAF-Upstream and kernel/common.
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 845 that´s built into Pixel 3 and Pixel 3 XL.
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 EAS implementation is heavily updated with changes from CAF, kernel/common and other improvements.
To have a read about our scheduler, which is called EAS, take a look here:
https://developer.arm.com/open-source/energy-aware-scheduling
Main Features:
- Based on latest kernel sources from Google, Kernel is made for Android 12 (Android S)!
- Linux-Stable-Upstream included to latest 4.9.304
- compiled with prebuilt Clang 13.0.1 from Google and built with -O3 optimizations
- ZRAM patched up to latest kernel/common state and useZSTDLZ4 as default compression algorithm to improve memory managment (more info see this post regarding the earlier switch to ZSTD) and this post regarding the switch back to LZ4
- fixes the magisk freezes caused by f2fs-stable
- Safety Net patches are included -> Kernel passes Safety Net
- Wake Gestures from @flar2 included
- Flashing the kernel will keep root!
- Tested to work on custom ROMs
- Flashable via EXKM and FKM on a rooted system!
- AnyKernel3 powered by @osm0sis (big thanks!)
EAS related features:
- EAS implementation patched up to latest CAF state
- Schedutil is patched up with kernel/common and CAF patches to improve performance and efficiency!
- Memory Leaks inside EAS are fixed
- disable autogroups and use cgroups for more efficient task placement!
- Enable sched_min_task_util_for_boost_colocation feature from CAF
CPU related features:
- Power saving workingqueues enabled by default (toggleable in EXKM)
have a read here: https://lwn.net/Articles/731052/
this complements EAS in general
- Change various drivers (WLAN, MM, audio, charger, power, thermal, glink etc) to user power efficient workingqueues. This should work well in conjunction with EAS
- improved Schedutil governor
- Add hold functionality to schedtune CPU boost
- WQ_HIGHPRI for the IO and crypt workqueues (replaces googles approach with a better upstream one)
- cpufreq/times vastly improved
File System related features:
- Include rapid GC by @arter97 ( best thing is to read the commit description linked here. I compared GC on stock google f2fs, upstreamed f2fs and f2fs with rapid GC. Rapid GC is the most effective, followed by upstreamed f2fs.)
- Set the bio REQ_NOENCRYPT flag (When lower layers such as dm-crypt observe the REQ_NOENCRYPT flag, it helps the I/O stack avoid redundant encryption, improving performance and power utilization. )
Usability related features:
- High Brightness Mode for increasing backlight level related to brightness accessible via EXKM app
- High Brightness Mode for just boosting display to max level accessible via EXKM app
- Vibration Intensity adjustable via EXKM app
- Backlight dimmer functionality included (adjustable via EXKM App)
GPU related features:
- KCAL to control the display
- KLAPSE integrated
- KCAL/KLAPSE: changes safety measures -> allow completely disabling two RGB values (this was requested to, for example, only have red values on night dimming)
- Enabled NAP power saving state of Adreno 630
- improve GPU profiling for improved rendering performance (1,2 , 3 )
- Update GPU driver to latest CAF state
Network related features:
- Wireguard Support (Details)
Memory related features:
- Enable Userspace LMK/freak07/Kirisakura_bluecross/commit/aac453635549699c13a84ea1456d5b0e574ef855"]2[/URL])
- Patch up kernel LMK backend (PSI) with kernel common upstream
- ZRAM patched up to latest kernel/common state andZSTDLZ4 as default algorithm. (information can be found in this post regarding the switch to ZSTD, which is now reverted) and this post regarding the switch back to LZ4
- possibility to use lzo-rle as default ZRAM compression algorithm (more information here and there )
- possibility to use zstd as default ZRAM compression algorithm!
- Speculative Page Faults (1. 2)
- Fix various memory leaks in different subsystems
- Reap memory of a task that receives sigkill
- various other changes from mainline
Sound related features:
- Adjust microphone gain via sound control in EXKM
- Adjust speaker gain via sound control in EXKM
Security related features:
- CFI and LTO both kept intact and are used to keep additional security Google implemented for us!
- Shadow Call Stack
- built with latest clang found on google repo
Misc Features:
IO-Schedulers:
- cfq
- maple
- deadline
- noop
- tripndroid
- fiops
TCP Congestion Algorithms:
- advanced algorithms enabled
- includes new bbr and sociopath tcps
Wakelock Blocker:
- advanced wakelock blocker with the ability to block any wakelocks (dangerous, use with caution)
- please read this for further info
Other features:
- enable some additional Sony and XBox controllers
- add support for steam and nintendo switch controller
- patches to loop device, xfrm and usb gagdet
- disable logging to make the kernel more lightweight in various places
- add support so you can enable faster charging for non pixel wireless charging stands (use at your own risk, disabled by default, how to enable here)
Feature section for the "non visible" but perceptible improvements:
- updated binder section (responsible for interprocess communication)
- updated sdcardfs ; have a read about it here:
Requirements
- unlocked Bootloader
- USB-Debugging in developer options enabled
- latest adb and fastboot binaries
- working adb and fastboot environment
How to flash the Kernel:
1. Download the kernel.zip to your device. Make sure your device is rooted properly, with the magisk version suiting your current firmware version.
1a. Optional: While it may not be necessary all times, you may want to restore stock boot.img, reroot with magisk and optionally install twrp.zip if coming from another kernel. Before reporting issues make sure you do that! Thank you!
2. Flash the kernel.zip via either a kernel manager app capable of flashing kernels or TWRP if available. Make sure whatever method/app you decide to use, supports your current Android Firmware. Apps/Recoveries need to be possibly updated for firmware updates!
It´s your job to ensure compatability.
Flashing the kernel will preserve root.
3. Reboot and profit! Before reporting any issues make sure to read the Release-Post of Bluecross_Q_Release_1.0.0!

Source Code: https://github.com/freak07/Kirisakura_bluecross/73Update to 3.0.0
Hey guys and girls,
So here´s the next milestone update. I tried to put this release off for as long as possible, but I finally feel it´s ready to be released here.
The reason why I was so hesitant, is that I don´t want to introduce any instability. The current kernel has run for me for months, without a single reboot.
Don´t get me wrong the new release is absolutely fantastic. I´m quite sure of it
This new release is not an update but rather a complete new kernel! I started to work on the idea a few months ago. Progress was made a month ago, after I spent way too much time on this and was on the verge of giving up. But here we go now. Thanks also to @arter97 who answered a few questions
The new kernel is completely redone from scratch.
It´s based on latest Q Preview Source from Google. Only a few commits, which ensure compatibility with Android Q needed to be reverted. So far that´s the same as the old kernel.
But this time I managed to completely merge the latest CAF source into it. CAF stands for Codeaurora Forums, where the development of Qualcomm Code happens.
As @nathanchance correctly observed the Pixel 3/XL kernel is more CAF than the Pixel kernels from earlier years. See this twitter post for Pie and the trend continues for Android Q.
Earlier I would only pick a few selected CAF patches. But now the complete CAF tree is merged in our tree. This includes hundreds of commits for SOC specific drivers, other improvements, stability fixes etc.
It gets better. The kernel is specifically rebased on to the new LE.UM.3.2.1-11600-SDX24-Tag, which contains a lot more improvements and cutting-edge changes than the regular sdm845 tag.
Performance is way better, than the old kernel. I think everyone will be pleased.
The only things, which needed to be reverted completely from CAF was the dynamic CLK addition for the display driver. But that´s incompatible and currently not worth it. Maybe it might be later looked into. I also decided to not touch the drivers responsible for charging.
New improvements from the Pixel 3a/XL devices are also merged in this kernel. WiFi driver is updated to latest state from Q Preview 3. We should have a lot more fixes on that front now too.
Audio driver is updated to latest CAF state and Q Preview 3 state as well. The audio driver is released in a separate repo from Google/CAF and needs to be updated alongside the kernel to ensure compatibility with our new shiny CAF base.
While redoing the kernel I decided to drop a lot of stuff, that previously aimed at helping with performance.
We dropped back to Google´s way of touch/interaction boosting. No custom CPU Boosts any longer. Performance is excellent and battery life too. Only the underlying EAS machinery is updated. So far that works very good.
I also dropped a few other "under the hood" things you won´t miss after flashing the kernel.
There are a few commits from @arter97 ´s OP6 kernel, which should improve things a bit more.
The memory leak fixes from @Sultanxda are included as well. Thanks to him!
There are many more changes and improvements, please feel free to take a look at my git!
I tried to update the OP as best as I could.
All features like wake gestures, sound control are still in their place. If you find something missing please report back.
Oh and it included 4.9.176
This kernel is tested for over a month now! It´s perfectly stable and no issues for me or any of my testers. As already said I put so much work in to it, I hope it pays off and everybody has the same feeling as me.
This kernel should leave us with a good time until Android Q officially drops
Just in case:

Hey guys and girls,
So here is the next update for you guys. Got a little bit later but here it finally is.
The kernel is still made for Pie! It won´t work on Q.
I wish everybody a nice day/evening!
Changelog:
Kernel Base Changes
- Merge Q Preview 5 Code
- Merge 4.9.184 and 4.9.185
- use prebuilt Clang 9.0.5 from google
- add lzo-rle compression for ZRAM (this is not set as default, you have to change it yourself)
Important
All flashing errors are now fixed. If you experience the ramdisk error please take a look at the FAQ.
Have fun flashing and enjoy your device with latest linux-stable
Why is linux-stable important?

If you like my work and want to buy me a coffee/green tea: http://paypal.me/freak0750Hey guys and girls,
Yes I know it took a very long time, but here it finally is. There are some changes now compared to the releases starting with 3.0.0.
A few words to describe why the kernel is now the way it is.
The biggest change is that the kernel has not merged a complete CAF-SDX base update, like what was done in 3.0.0. (detailed description what was done in 3.0.0 here)
I tried several times, started everytime from scratch (this process took the better part of a day or more, every single time I tried!), excluded some changes from the CAF-Base, but I cannot get the kernel to boot. I´m not able to figure out what´s preventing the kernel from booting with CAF merged completely on Q. The same changes boot fine on Pie, but something prevents booting on Q.
I spent so much time on trying to get the kernel to that state again, that releasing it without the complete CAF-Merge is a hard decision, but the decision had to be made.
On a bright side: Google updated the CAF-based camera driver heavily, very similar to what I did before
Several other subsystems are now on a way more recent state compared to when Pie was released. That´s very promising to see and great work by Google.
I combed through the CAF source and merged several "individual" changes in the kernel I deemed viable, one by one.
So EAS is now again at the latest CAF state, some memory leaks are fixed and other things work a bit better.
But all in all the Q Base Kernel from Google is already very good.
I tried to keep all the features of the Pie-Release available and built a good kernel for our device nonetheless. Every tester told me so far the device feels improved in at least a way and now I´m content to release the kernel.
I will update the OP to reflect some of the changes and to keep it as recent as possible. The biggest change is the absence of the complete CAF-Merge however. These were mostly under the hood changes, so it might not be obviously visible.
A few things which are still notable:
- lzo-rle is still available as a ZRAM compression algorithm
- additioanlly zstd is available as a ZRAM compression algorithm
- swappiness can be set to a higher value than the default 100
setting swappiness to a higher value than 100... WHY?
swappiness controls the relative amount of swapping memory pages and dropping the cache.
Having swappiness at 100 means memory and cache have same priority.
With swappiness set to 0, memory will never be swapped out in favor of cache, so the kernel will always drop cache first because it will never swap out any memory.
With swappiness set to a higher value than 100, swapping memory has more priority than dropping the cache
Everybody can experience with this. I will leave the 100 by google as default but I went with something between 160 and 190 on my device
Different ZRAM algorithms? Which is the best one for me?
This is a difficult question to answer in a very exact fashion. Have a look at this benchmark and the various graphs here: COMPRESSION BENCHMARK
The most simple answer is just use lz4, which is also the default one. Very good compromise of compression ratio and speed.
lzo-rle aims to fit the need of ZRAM better than just a "generic" compression algorithm. (there´s an explanation and link earlier in the thread, linked in a release post, search for it )
zstd is a "younger" algorithm, which is very fast, if one does compare the compression ratio (which is way higher than lz0 and lz4) to compression/decompression speed
Thanks to everyone for not constantly pestering me about an update, for the patience and that the thread was quiet quietly
Important: What to do if you face issues on Android 10/Q
You might face issues on Android 10 like non working sensors, edge sense not working properly or similar things.
Here´s a thread that has more info about it: https://forum.xda-developers.com/pixel-3-xl/how-to/android-10-sensors-bug-t3964904
This also caused seemingly in a random fashion issues with magisk modules not unpacking properly when you flash them via magisk manager.
So if you have used TWRP in the past and went on to Q, without completely wiping you might very well be affected.
I recommend everybody who faces symptoms of random issues, which they cannot explain, to completely nuke their device and flash a factory image with -w intact, as to complete set up the device from scratch.
This will wipe your whole phone, so backup videos, photos, music, apps and other stuff you don´t want to lose!
@jcmm11 and me were hunting this magisk bug for a week and it turned out it´s connected to the above mentioned issue, although it gets more prominent by the latest CAF - EAS changes, which are merged in my kernel. Probably due to the way tasks get handled a bit differently.
Please everybody keep this in mind, before reporting back.
Just in case:
Special thanks to, @jcmm11 , @MArtyChubbs, @melgar and @Paddybecks87.
Another special thanks to @osm0sis for creating and maintaining anykernel for us all. But that´s not enough, hehelped me out big time to setup, refine and improve my AK3 zip, because my scripting skills just suck big time! Huge thanks to you!!!
I wish everybody a nice day/evening!
Changelog:
- I´m sorry this time you have to read my massive story again
- Rebased the kernel on the offical Q-Kernel Source from Google
- No complete CAF-Merge
- Upstreamed to latest linux-stable
- Keep all previous features intact
- Update EAS again to latest CAF-State!
- merge changes from kernel/common
