Update to 5.1.1_S

Hey guys and girls,

Here´s the next release. It includes the kernel-side security patches for the June firmware from the still updated 4.9 devices (p3a series).

Linux-stable was updated as well.

I was able to flash the kernel.zip fine running magisk canary 25001 on latest stock rom source. If you had troubles with latest magisk canary, maybe that zip solves it. Otherwise if custom roms don´t work, I don´t know what could be the cause as it works fine on my end.

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.

Changelog:
- Google Code merged to June for 4.9 kernels
- Linux-Stable to 4.9.317
- update anykernel3 zip, thanks to @osm0sis

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?

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.

This kernel saved my phones life. Was getting tired of the freezing in the Pixel Experience, now it runs extremely smooth. Thank you!

I'm on blueline, 5.1.1_S, LineageOS 19.1 (June 14), Magisk 24.3. No issues to report.
I haven't tried updating Magisk yet.
Might be time to start a spreadsheet of what's working and not.
Would logs help?

I'm using Pixel Experience June patch. Even with a completely stock PE boot image (no magisk), flashing 5.1.1_S causes the bootloop immediately.

Click to expand...

Click to collapse

Unfortunately I don't know what can be the cause, but it seems something is not right when flashing on source built custom Roms.

The reports started when magisk 25 dropped though even with zips that previously worked. So it might not be the kernel, but rather down to magisk and/or something the custom roms changed.

This is not compatible with latest Magisk 25.0 if anyone was wondering.
Hopefully for the developer to extend its support!

Kirisakura-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 4.9.317
- compiled with prebuilt Clang 13.0.1 from Google and built with -O3 optimizations
- ZRAM patched up to latest kernel/common state and use ~~ZSTD~~ LZ4 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 and ~~ZSTD~~ LZ4 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!

Update 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:

If you face issues, please return to a stock environment, only your rom plus magisk root, without any modules, scripts, tweaks or mods and see if you can reproduce the issue.
Tell me the exact steps needed to reproduce.
Then send me a dmesg and a logcat (if the kernel crashes not) or a ramoops (in case the device reboots). Take a look at the second post for a guide on how to obtain these.

Special thanks to @Paddybecks87, @MArtyChubbs and @melgar

I wish everybody a nice day/evening!

Hey 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:

If you face issues or bugs when running the kernel, please return to a stock environment, only your rom plus magisk root, without any modules, scripts, tweaks or mods and see if you can reproduce the issue.
Tell me the exact steps needed to reproduce.
Then send me a dmesg and a logcat (if the kernel crashes not) or a ramoops (in case the device reboots). Take a look at the second post for a guide on how to obtain these.

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
- add zstd as available zram compression algorithm
- allow swappiness to be set to higher values than 100
