There´s something else called doze at play, which puts the phone to a "deeper" deepsleep state if no motion etc is detected for some time (e.g. overnight). If you constantly check the phone, this mode is likely never be entered.
Where? :)
I found only Background app management accessible from battery settings (general switch) or it can e accesed from any app-info-battery. I couldn't find there doze at play.
And there is Adaptive battery settin which you didn't mention. What this option does?
And there are also some battety/ram related option - OptiFlex. Could you please advise how is it working? Does it also send apps in background to deep sleep which are not ticked in OptiFlex or it works different way?

And .72 update OTA is released. Are there any kernel-related changes?

Thank you for the great kernel!
Is there any chance to make this compatible with LineageOS 19.1?

Basically, it is working with LOS, but there is an issue with Fingerprint reader, which does not work at all.

Attached to this post you will finf a kernel that´s compatible with LOS and LOS-based ROMs. I used magisk stable 24300 while flashing.

Please note this comes without any form of support from me as I can´t change between stock rom and custom roms all the time in case something is not working perfectly.

The last version of this kernel for stock Android 11 seems to be killing TWRP.

Steps to reproduce:
- Have a Zenfone 8
- Have an unlocked bootloader
- Have the latest stock Android 11 (30.12.112.82) on it
- Have the latest TWRP (3.6.1_11-0-I006D) installed
- Install Kirisakura_Sake_1.7.9.zip via TWRP
- Reboot to Recovery

Expected behavior:
- Phone reboots back to the TWRP recovery interface

Actual behavior:
- Phone "ramdumps" after the TWRP splash screen

Fixable by flashing back the stock image, but makes using TWRP+Kirisakura impossible.

Sorry, but A11 is no longer supported.

On the zf8 if you permanently flash TWRP it shares the kernel with the system.

As this kernel deviated a lot from the stock kernel sharing the kernel seems no longer be possible with your configuration on A11.
I can´t confirm if this is exactly the issue you´re running into, but I suppose it is.
As a workaround have you tried booting TWRP instead of permanently installing it? That will make TWRP boot with its own kernel. Might fix this issue.

fastboot boot twrp.img

If that also doesn't work, it means TWRP is not compatible with the dtb shipped in my kernel. But there's nothing I can do about it now.

    Bump. Did anyone flashed the kernel above .72 ? Does it run without issue ?
    I've been using it for three days now on .72, and I haven't got any issue. But I can't confirm this version fits perfectly the latest asus build, so do a backup of your current kernel before flashing kirisakura if you want to try using it

    Kirisakura-Kernel for the Asus Zenfone 8

    Hello everyone,

    To keep it short: Here is Kirisakura - Kernel for the Asus Zenfone 8 aka Sake. The Zenfone line-up internal codenames are traditionally derived from alcoholic drinks. Two years ago the Zenfone 6 bore the title "Kirin". The Zenfone 7 was codenamed "Tequila".
    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!
    If you expect a custom kernel to magically improve your devices battery life manifold and this is your only priority then this might not be the right place for you.
    However the kernel is built to keep battery life close to the same as you would experience the on stock kernel while being tuned to perform better in various UI related benchmarks. The same benches are used by google to verify and ensure UI smoothness on the Pixel devices. The scheduler is tuned to yield lower jitter and reduce jank frames.
    If that got your curious, I welcome you to continue reading if you´re still interested!


    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 foucs during testing! This includes Linux-Stable, CAF-Upstream and kernel/common.


    A very positive development. Google pushed for CFI and SCS to be enabled by default in the android-common kernel. In this years generation ( 5.4 linux kernel base/ SD 888 ) CFI and SCS are enabled by default. It was a lot of work to get these features working nicely on the kernel I did the years back. So it´s nice to see this is now there by default in everybody can profit from it.
    I put the explanations and links in hide tags here.

    Kernel Control Flow Integrity (Kernel-CFI), which is achieved by linking the kernel with LLD and Link Time Optimization (LTO), more precisely ThinLTO, are quite unique security features.
    The recently released Kirisakura-Kernel for the OnePlus 8 Pro was featured on the XDA-Portal due to the inclusion of CFI. The featured article explains CFI in great details, is easy to understand and definitely worth to read.
    If possible the latest Kirisakura-Kernel releases for various devices aim to include CFI in enforcing mode so users can benefit from this security features.

    Another security feature is Shadow Call Stack (SCS).
    SCS is another security patchset that is aimed at preventing attacks via return oriented programming (ROP).
    ROP is a technique where the attacker gains control of the kernel stack to overwrite function return addresses and redirect execution to carefully selected parts of existing kernel code.
    If you´re interested here are a few good links:
    Google Security Blog explaining SCS.
    LLVM doc about SCS
    Android DOCs documenting SCS

    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.
    Read more about the Release-Model following this link.
    This conversation on the LKML mailing list also shows the power of Linux-Stable and why it´s very beneficial to not just say it´s not worth and a potentiol source for bugs:
    Starting with the Initial Message , the following reply and a good summarizing statement.



    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 888 that´s built into the different SKUs of the Zenfone 8.
    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 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!


    Main Features:
    - Based on latest kernel sources from Asus for Android 12 and intended to be used on the latest Asus Stock-Firmware
    - compiled with Clang 14.0.7 and built with -O3 speed optimizations
    - Linux-Stable-Upstream included to 5.4.199
    - upstreamed CAF base for the Snapdragon 888 (qcoms internal codename "lahaina")
    - include important fixes/improvements from kernel/common
    - tune scheduler for improved jitter and less jank frames
    - reduce power consumption during deep sleep
    - remove logging while device is suspended
    - remove sleep debugging from Asus for release build
    - disable various debugging mechanisms for drivers which are not needed on a perf build (for example touchscreen, fingerprint reader, display, binder)
    - disable various debugging configs, that are not needed in a perf kernel build according to google.
    - disable selinux auditing (we don´t have to adress selinux denials running a stock rom)
    - display tweaks to reduce power consumption on statically rendered images
    - disable unnecessary CPU errata for our specific SoC
    - disable per cgroup pressure tracking to reduce overhead
    - free up RAM by removing reserved mem regions used only for debugging
    - implement LRNG (thanks @arter97, see arter kernel OP for more info )
    - Flashing the kernel will keep root!
    - Flashable via EXKM, FKM or TWRP (if available) on a rooted system!
    - Anykernel zip is based on the Anykernel3 release from @osm0sis


    EAS related features:
    - Implement dynamic WALT-Window size depending on current FPS, collecting information about CPU-Load to provide more precise information for the scheduler
    - EAS implementation patched up to latest CAF state
    - updates from kernel/common
    - scheduler updates from sd888/ 5.4 kernel
    - scheduler update from sony xperia 1 III kernel aiming to improve WALT

    CPU related features:
    - Power saving workingqueues enabled by default (toggleable in EXKM)
    - Change various drivers (WLAN, MM, audio, charger, power, thermal, glink etc) to use power efficient workingqueues. This compliments EAS in general
    - improvements to cpufreq/times/stats
    - vdso32 patches as found on Google Pixel devices (brief documentation here) (CAF 5.4 default, keep for documentation)
    - remove event debug logging
    - disable broken irq detection, disable debugmon
    - improve suspend/resume from audio driver (caf-upstream for audio-kernel)
    - cpuidle: wake only cpus for which qos has changed (this allows cores to keep idle states better)
    - disable debugging during sleep states as per qcom recommendation
    - remove RTB logging to reduce overhead
    - disable trace_printk as it shouldn´t be used on production/perf kernel builds
    - enable suspend_skip_sync to save power during suspend/resume
    - disable edac and coresight (following google on the pixel kernels)
    - disable jtagv8 debugging as recommended by qcom for perf builds to avoid potential power, performance and memory penalty
    - disable s2idle in favor of deep idle state -> improves deep sleep drain (google initially used 2idle for improved suspend/resume latency on pixel 3 and pixel 4, but disabled it on pixel 5. qcom followed suit for sd 888, but apparently didn´t see google reverting it on pixel 5. Other OEMs such as Xiaomi or OnePlus already disabled s2idle on their SD888 devices in favor of deep- read more about s2idle vs deep here)

    GPU related features:
    - GPU driver updated to latest CAF-State
    - gpu/kgsl improvements from pixel 4/pixel 5 kernel
    - add low_prio_worker thread for gpu driver (Improves performance when tearing down processes (eg, via LMK) and not blocking currently running UI from submitting work to the GPU

    File System related features:
    - upstream BFQ-MQ to latest state in linux-mainline and default to 128KB readahead
    - improve memory allocations in kernfs
    - ufs improvements from pixel 4/ pixel 5 kernel
    - improve GC as to not interfere while user interaction is happening and prevent possible jitter or latency spikes

    UI/UX/Usability related features from CleanSlate:
    - CleanSlate features made by @tbalden
    - Disclaimer: All CleanSlate features can be controlled via the free companion and config app found on CleanSlate thread here on the Zenfone 8 Forums on XDA. Please consider buying the premium versions if you enjoy using the CleanSlate features, to give a little something back to @tbalden.

    Network related features:
    - Wireguard Support (Details)
    - advanced TCP algorithms enabled
    - use bbr as default TCP congestion algorithm (fasted algo according to this excellent research from @kdrag0n found here )
    - includes new bbr
    - improved networking drivers from caf-upstream (especially wifi)
    - remove unnecessary wakelock from WLAN driver to reduce thousands of very short wakeups during a 7 hour deep sleep period
    - improved bluetooth performance (¹, ²)
    - Enable support for TTL spoofing

    Memory related features:
    - Speculative Page Faults left enabled (1. 2) (CAF 5.4 default, keep for documentation)
    - Fix various memory leaks in different subsystems
    - improved mm with patches from mainline
    - patches from kernel/common
    - improve memory allocations in various subsystems, video encode/decode, kernfs, cgroup
    - Backport to enable CONFIG_HAVE_MOVE_PMD (see here) , thanks @arter97
    - Backport to enable CONFIG_HAVE_MOVE_PUD (commit here) , thanks @arter97
    - free more RAM by removing unused reserved memory regions
    - mm: Micro-optimize PID map reads for arm64 (improves game performance, especially unity based games such as genshin impact)
    - MGLRU added (info here and here

    Security related features:
    - Control-Flow-Integration (CFI) and Link-Time-Optimization (LTO) (CAF 5.4 default, keep for documentation)
    - Use ThinLTO which was first used in the Pixel 4 XL Android R-Kernel instead of full LTO (CAF 5.4 default, keep for documentation)
    - Shadow Call Stack (SCS) Security-Feature ( 5.4 default, keep for documentation)
    - enable init_on_alloc for even more security, more information can be found in the commit message (CAF 5.4 default, keep for documentation)


    Misc Features:

    Wakelock Blocker:
    - advanced wakelock blocker with the ability to block any wakelocks (dangerous, use with caution)
    - please read [URL="https://arstechnica.com/gadgets/2018/08/p-is-for-power-how-google-tests-tracks-and-improves-android-battery-life/"]this for further info
    - blocking a kernel wakelock should only be done in case of firmware incompatabilities (WiFi network at work (can´t be changed) causes deep sleep to not work on the phone.) That´s the only use case I see for this feature. The kernel does not features this to improve battery life!

    Other features:
    - clean up asus drivers and fix a few warnings in kernel log
    - disable logging and debugging to make the kernel more lightweight in various places (includes binder, mm, vma, gpu, ipa etc)
    - fix several coding issues detected by newer Clang-Toolchains
    - enlarge dmesg size to ease debugging


    Flashing Guide, Download and Changelog

    Requirements:
    - unlocked Bootloader (this will void warranty and kill future OTA updates on all asus phones at the moment)
    - USB-Debugging in developer options enabled
    - latest adb and fastboot binaries
    - working adb and fastboot environment
    - magisk root
    - a backup of stock boot.img, vendor_boot.img and dtbo.img so you can go back to stock conditions (simplest way is TWRP or to extract from stock firmware)

    How to flash the Kernel:
    1. Download the latest kernel.zip and make sure you have properly updated to the latest matching Asus Stock-Firmware. When the Zenfone 8 receives an OTA update it takes Asus a while to release the source code for the new OS and me a while to build a new kernel. If you don´t want to face any issues, wait until I either release an updated kernel or give green light because there were no kernel changes.
    Always make sure to run the firmware the kernel is built for!
    If you feel adventurous and try in advance, make sure you have a backup ready!

    2. Flash the kernel.zip via latest TWRP (if available), EXKM or FKM app and do a full reboot.

    3. Reboot and profit.

    Update to 1.0.8

    Hey guys and girls,


    Alright so here´s the next update. The asus source for the new updates didn´t contain anything that we didn´t already have by merging CAF and linux-stable upstream.

    However it was time for an update.

    After flashing the kernel.zip there will be a magisk module in magisk manager called AK3 Helper Module. Do not delete it.

    The link to the latest firmware can be found here:

    Update to 1.0.0

    Hey guys and girls,


    I hope everyone got smoothly into the new year. A bit late, but Happy New Year to everybody.
    The Android 12 update arrived.

    Kernel was rebased from scratch as Android 12 uses a different qcom base than Android 11. This was a lot of work, but it went more smoothly than I expected.

    All previous features and changes should still be intact. Android APIs changed on Android 12, so some kernel changes for CleanSlate apps were necessary. Please update the CleanSlate apps according to the instructions on the CleanSlate thread here and here.

    After flashing the kernel.zip there will be a magisk module in magisk manager called AK3 Helper Module. Do not delete it.

    Freak07,
    Hi,
    Will you update your kernel for current firmware (.43) ?
    Thanks!

    When I find time. They bumped the CAF-Base, but my kernel is still ahead.

    This creates a lot of conflicts during merging. Either I need to start from scratch again or check in detail how much work merging and fixing all the conflicts will be.
