Is there anything in the Kernel or configuration/companion app that speeds up the "deep sleep" state?

I have only 60% deep sleep which is caused by very long activation times to get into deep sleep after the screen is off. I do not know yet how to trouble shoot what is preventing my phone from going into deep sleep faster but I was hoping that the kernel or companion/configuration can enforce a faster deep sleep state?

During a night: 98% deep sleep with like 2% battery loss
During a work day: 50-60% deep sleep

as a short answer: no and you probably don´t want that.

a longer answer: the kernel can´t know what´s happening on your phone or what you´re doing with it.
If there´s nothing to be done from any app/service or other processes the system/framework "asks" the kernel to go to sleep and it will do so, eventually entering deep doze (where the system/framework also limits network traffic and wakeups etc). that´s what´s happening during night and it works fine for you.

during the day if you actually use your phone the system/framework requests the phone to wake up/wakelocks. depending on your location you might have bad mobile reception, switch network often, bluetooth devices connected, wlan connected, you receive notifications, listen to music/podcasts, make calls, have a bluetooth watch connected etc....
If you listen to music/podcasts or call someone while screen is off during the day, the phone can´t deep sleep during that. If you receive notifications the phone won´t deep sleep. If you receive notifications while on bad network the phone will stay awake for longer. If you´re constantly switching networks the phone won´t sleep as much as when it´s stationary overnight and enters deep doze if you don´t touch it for 20 minutes.

Then there can be apps that keep the phone awake for longer as necessary when it should be sleeping (there can be many reasons, sloppy coding, "spying", collecting information, making sure you really receive notifications), but again the kernel can´t know that. To get back to the beginning, you wouldn´t want the kernel to always force deep sleep as your phone would not function properly then.

Depending on what you´re doing 60% deep sleep can mean, let´s say your day spans 15 hours from 7-22. That means your phone sleeps for a bit less than 10 hours of that entire 15 hours. If you have 3 1/2h of SOT, that leaves your phone awake for 1 1/2 hours - 2 hours. If you make some calls, get notifications, switch screen on/off regularly (as opposed to never during the night) that´s plausible if one of the factors above apply (bad network, switching networks, lots of apps syncing, bt devices connected)
It all depends on your personal usage patterns and the factors I described above. If the phone is used for extended periods of time and then just kept idle for extended periods of time it´ll end up with more "deep sleep", as opposed to checking it every few minutes for a minute reply to texts etc.

Uh thanks for the detailed response.

I am definitely prone to bad phone signal on my office location but I am also always connected to good WiFi signal.
So deep sleep does limit network traffic meaning telegram/whatsapp/signal/fairmail/etc will all not work as expected anymore? And if I have them "not optimized" they will keep working but prevent the system from going into deep sleep?

I know this is not kernel and topic related but:
Would "Naptime" or "Greenify" help with putting the system into deep sleep when using any "spying" or bad coded apps? Or would there be any "reasonable" way to figure out if I have any of such apps?

guys. i just saw in gsam app, that my phone does only go in light doze and not deep doze. is this app related (and just does not work properly with the 6 pro) or is sth wrong here?

if your device deep sleeps it does deep sleep. if an app or a service wants to work it needs to request a wakelock, waking the device. that´s the simple explanation.
You´ll see it as an alarm, a wakeup , a partial wakelock or a kernel wakelock in bbs, similar apps or battery historian.
Some of those wakelocks belong together, if you´re device is sleeping while connected to wlan, an app or the system wakes up and needs wifi connection, you´ll see a bunch of wakelocks. wifi, activity manager, a wakelock for the app, a wakelock to wake up the ril.

If you really want to figure out what´s happening you need to invest a lot of time, now that BBS is not fully functional. You can try to tackle it from different fronts. Disable mobile network entirely while you´re in the office and solely rely on wlan. you can try to uninstall apps one by one and see if that makes a difference.
You can try to change your usage pattern. Let your phone sleep at the office without touching it for 3 hours there and check deep sleep then.
I don´t know anything else besides BBS or battery historian. I generally don´t like to use apps such as GSAM or those other monitors, but I did when I got the pixel 6 pro as BBS wasn´t working properly. I also don´t use monitors for active and idle drain such as in FKM or EXKM.

But again, it doesn´t sound that bad, if your usage is similar to what I described above.

But this derails this thread further and further. It´s unrelated to the kernel.

I personally don´t use apps like naptime or greenify. I gladly trade a few less % of deep sleep over day, so that I don´t get delayed or missed notifications.

guys. i just saw in gsam app, that my phone does only go in light doze and not deep doze. is this app related (and just does not work properly with the 6 pro) or is sth wrong here?
let´s please move this discussion out of this thread. It´s getting more and more unrelated to this kernel and the subject of this thread.

I don´t mind occasional off-topic or explaining certain things (even multiple times), but this isn´t the right place for it.

I answered basically the same thing to @Utini in the thread that was created here:

Good find, thank you for the report! It's related to a bug in the pixel6 detection in the app I didn't notice yet... rolling out an update to the play store with a fix. As soon as google approves it, should be available.

I can confirm that after updating the Companion app to the version 3.3.3 (162), flag Enable Proximity Sensor Screen on is now visible. After setting it to off and rebooting, it's not locked to 60Hz anymore.
Thanks again!

Hey there @Freak07 , will you wait for the December update next week before releasing a new kernel? Cheers mate.
yeah I guess next update will drop alongside whenever december source code drops. :)
as of right now I´m just enjoying the device and the kernel in its current form.

thanks for reporting back, glad it´s working fine now.
hats off and thanks to @tbalden for the quick fix! :)

Is this kernel beneficial for battery life?

I've not used a kernel for years but feel the 6 Pro needs some tweaking

Will my gpay still work or do I need to do anything extra?

every user has their unique usage patterns, so nobody will be able to definitely answer the question for you.

The only two things that definitely will improve drain:
take a look at the first post. If your usage includes listening to music/podcasts with screen off during the day, the provided magisk module, which tunes the powerhal will improve battery drain a bit.

in the CleanSlate config app, you´ll find a batterysaver that restricts max cpufreqs at 3 chooseable levels, which will improve battery drain as well. (if you´re willing to restrict max cpufreqs during regular usage.)

Battery life on this phone is pretty stellar to me though, so I have nothing to complain. :)


edit: gpay will stop working as soon as you unlock your bootloader. that´s unrelated to the kernel.
safetynet can be fixed, via other means though so you can get it working after unlocking, which is a requirement to flash the kernel! :)

If you want to use GPay on unlocked phone then you need to root and use magisk and saftynetfix to make gpay work. there are threads on this already on forum.

Hello a noob question after installing this kernel, i lost root (magisk) any ideas plz ?
Of course you did - you flashed a boot.img that doesn't have Magisk installed?

2a. If you want to stay rooted patch the provided boot.img in magisk manager prior to flashing it via fastboot. Of course you need to adjust your command to flash like you did when rooting the device.

Looks like you missed the above step in the OP. Patch the kernel's boot.img in the Magisk app and flash it again to recover root.

And just to add a bit related to my own experience, blocking those 2 WLAN-related wakelocks seems to help a bit with my idle drain (maybe a decrease of .1% compared to stock?) as well as adding roughly 9% to my deep sleep percentage.

    Update to 2.4.0

    Hey guys and girls,


    Alright here´s the next update and it´s fine to flash on May firmware. As I suspected we already had all the changes for May by merging upstream.
    I´ll include the changelog from 2.3.0 as well in this release post, since I think a lot of people flash the kernel on a monthly basis when the security updates drop. So this post pictures the changes going from 2.1.0 to 2.3.0! As I said 2.3.0 was kind of a final rehearsal to make sure everything is good for the May update.
    I´ll put a remark behind changes going from 2.3.0 to 2.4.0.
    This release is made for stable Android 12.1.0 May firmware. Not QPR Beta or A13 Beta!
    Once I find enough time or QPR beta gets updated, I might update the QPR beta release. No plans to support A13 beta.

    I also finished up the tables/graphs in regards to different binnings with the respective voltages on different tensor chips thanks to the dmesgs you all provided. I really want to put out a big thanks here to everyone for taking the time and participating. It was really great to see this kind of response.
    I´ll provide them in a post in this thread soon.
    So with that in mind we´ll get to the next paragraph were I could put those tables to good use.

    A few changes from A13 Beta are merged to the kernel so we can enjoy the improvements on A12 ahead of time. Most of them aim to improve the scheduler and task placement.

    However the recently dropped A13 Beta source contains a commit that can restrict max-cpufreqs based on PMU (Power monitor unit) reading. I setup this mechanism (lets call it "PMU Limiter") to mildly cut back max-freqs when they aren´t needed. It works quite well so far, with no performance impacts during scenarios where max cpufreq is beneficial. (e.g. app launching, camera launching, interaction etcetc)
    That means if a certain threshold is not crossed the max-freqs will be restricted to 1,4GHZ/1,6GHZ/2,4GHZ (for little/mid/big cores). As soon as the PMU detects enough pressure, those limits will be lifted.
    The frequency limits are based on tracing during various scenarios, benchmarking and also factor in the voltage table I was able to create. For example: 2.4GHZ for the big cores is the last freq step where a steady linear increase in voltage can be seen. Freq steps higher than 2,4ghz have a steeper slope.
    Keep in mind CPU-Freqs shouldn´t be touched in EXKM/FKM or other kernel managers. They are controlled by various mechanisms now (thermal hal, powerhal, pmu limiter etc) and values will get overwritten based on input.
    That means if you open the CPU section in a kernel manager, the maxfreqs will not be the actual maxfreqs that are possible. or the minfreqs might be raised. That´s normal and there´s nothing wrong if that´s the case.

    Additionally to the previous changes tasks of rt, sf and ta groups are now biased to start on high capacity CPUs during app launches, interactions etc.
    As usual, depending on your usage you may or may not notice a difference during these scenarios. :)

    While tracing I noticed kswapd often takes 100% cpu share when reclamation is happening. Since we use an 8 core cpu, an additional kswapd thread is being spawned during boot, which increases throughput for kswapd in these scenarios. Reasoning behind this can be found here.

    The trusty driver which connects to the fingerprintreader hal uses now a high prio workqueue when the phone is unlocked via fingerprint scanner. This means better performance, especially under stress. Keep in mind this is a kernel level change, it won´t magically improve fingerprint reader times manifold.

    DAMON and DAMON-Reclaim were removed from 2.3.0 going to 2.4.0. I tested the feature privately and it unfortunately collides with googles EH zram implementation causing the phone to crash at the moment. Tried to debug this issue, but no luck for the May release here.
    If you previously enabled the feature without adjusting the parameters properly and your phone didn´t crash, DAMON-Reclaim just didn´t do anything.

    2.4.0 also has an updated anykernel3.zip, which includes all the latest anykernel3 changes.
    Thanks to @capntrips we now have full support to resize vendor_dlkm partition which is part of the super partition. That means we finally can flash larger than stock vendor_dlkm partitions via anykernel3.zips and resize the partition properly instead of just dd´ing to it.
    A huge thanks to @capntrips for working on this and to @osm0sis for maintaining anykernel3.


    Disclaimer:
    I´ll keep the warning as to preferably using magisk stable to avoid potential issues as well here in this post.
    Please note that 24306 works fine for me though on non beta, stable May firmware!
    Important:
    Make sure you´re being rooted with magisk 24300 stable before flashing the kernel if you´re unsure. Any magisk version above 24303 might potentially lead to a reboot back to bootloader since android 12.1.0 and A12L QPR3 Beta. At the moment this only affects canary, but I put the warning just in case this will not get resolved in upstream magisk in time until the next stable drops. I saw a post that some modules also have problems with latest canary, so there´s a lot going on at magisk´s side at the moment.
    A post containing a short write-up how to "downgrade" magisk can be found following this link.

    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:

    - Linux-stable merged to 5.10.113
    - Use prebuilt Google Clang 14.0.5 for compilation
    - Utilize an additional kswapd thread to increase throughput for memory reclaim
    - remove DAMON and DAMON-Reclaim from kernel build (2.4.0)
    - improve trusty driver performance which connects to fingerprintscanner-hal by using high prio wq during fp unlock (2.4.0)
    - mm improvements from kernel/common (2.4.0)
    - improvements from kernel-common a13 to page_pinner
    - mainline backports for BFQ scheduler
    - rework Multi-Gen LRU implementation
    - scheduler improvements for RT (realtime) tasks
    - other scheduler improvements
    - include scheduler improvements from A13 Beta regarding better task placement
    - introduce and setup PMU limiter (prevents CPU from spiking to max when it isn´t needed, based on PMU reads)
    - bias tasks of rt, sf and ta groups to prefer high capacity cpus during app launches, interactions, camera launches, etc
    - updated anykernel3.zip (thanks to @osm0sis) -> adds full support for resizing vendor_dlkm ( huge thanks to @capntrips )

    Instructions can be found in the OP! Please follow the instructions to avoid any issues and read this post carefully. Don´t use magisk canary 24303 or more recent to avoid potential issues!
    If you´re coming from another kernel restore stock boot.img, dtbo.img, vendor_boot.img and vendor_dlkm.img before flashing. Thank you.

    I wish everybody a great day/evening!
    Have fun, enjoy the kernel and your phone.

    Update to 2.3.0

    Hey guys and girls,


    Alright here´s the next update. It´s a major one. I want to put it out shortly before we hopefully receive the next monthly security update on Monday kinda as a final rehearsal.
    This kernel is made for stable Android 12.1.0 April firmware. Not QPR Beta or A13 Beta!
    Once I find enough time or QPR beta gets updated, I might update the QPR beta release. No plans to support A13 beta.

    A few changes from A13 Beta are merged to the kernel so we can enjoy the improvements on A12 already. Most of them aim to improve the scheduler and task placement.
    A13 Beta source contains a commit that can restrict max-cpufreqs based on PMU reading. I setup this mechanism to mildly cut back max-freqs when they aren´t needed.

    While tracing I noticed kswapd often takes 100% cpu share when reclamation is happening. Since we use an 8 core cpu, an additional kswapd thread is being spawned during boot, which increases throughput for kswapd in these scenarios.

    DAMON patch-series is included to this release as it was merged to kernel/common. It includes DAMON-reclaim. You can read more about it here.
    This feature is currently disabled by default on this kernel. If you want to use it you can tune it to your liking as per the documentation linked above.
    The feature can be enabled via:
    Code:
    echo 1 > /sys/module/damon_reclaim/parameters/enabled
    I think Google might start to use it in the not so far future, but for now it´s disabled by default.

    May update is out. :)

    no source update pushed from google yet. I guess it´ll happen in a few hours when I´ll be asleep.
    I went ahead and flashed the latest release for stable 12.1.0 without any issues so far.

    If you can´t wait, it should be fine to flash based on that short experience.

    If you want to be absolutely sure there will be no issues due to incompatible source/firmware, I´ll try to update the kernel with any new potential changes in the source for May as soon as I find time, which will hopefully/probably be tomorrow if everything goes as expected. :)

    I wish everybody a great day/evening.

    The app is Crédit Mutuel

    And yes, you just gotta get to the actual log-in screen after accepting the conditions and cookies. At the log-in screen there will be a red warning that root has been detected.

    Thanks!
    Managed to reproduce the issue. It´s a magisk issue that surfaces probably since 2.0.1 where direct USB access was added and was not kernel related.
    To get direct USB access working a firmware file in vendor/firmware is replaced during bootup when my kernel is flashed, which is required for the kernel changes to actually work.
    The denylist trick to hide modifications stumbles upon that dir and fails due to a selinux error as denylist is not allowed to access that dir.
    As a workaround I fixed that selinux denial and root is no longer being detected by the app. :)

    After flashing the updated zip what I did was hide the magisk app in magisk manager, enable deny list and added the app to the list. Wipe data of the banking app, reboot (not sure if needed but rebooting is always good in these cases) and root was no longer detected by the app.

    Attached are zips which include the fix the selinux denial for you to confirm.

    This might also fix root detection by other banking apps that are not detecting root on stock kernel, but were broken after flashing the few last releases of this kernel.

    A12L QPR Beta Kernel

    For those on the A12L QPR Beta 3 here are zips to try. They are only supposed to be flashed on Android 12 QPR Beta!
    They should work fine on QPR Beta 3 as source was pushed already, merged and I have confirmation it´s working fine on Beta 3.
    That kernel has feature parity with the 2.4.0. So for a detailed changelog please refer to the release post of 2.4.0.


    I don´t know what´s the current situation with magisk and flashing kernels on QPR Beta, but it´s probably best to use magisk stable if you don´t want to face issues. (although I have confirmation magisk canary 24307 works fine with verity/verification disabled, don´t know about vbmeta enabled)
    I´m not myself on QPR Beta so please leave feedback, but remember:
    These zips are provided as is I don´t have time to flash between stable and QPR
    Feel free to report issues with proper bug reports (containing logs, steps to reproduce according to the guide linked in the FAQ), but they might remain unresolved if it´s not easy to fix without running A12L Beta on my own end.


    I wish everybody a great weekend!
    Have fun, enjoy the kernel and your phone.

    Kirisakura-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!

    Features:
    Main Features:
    - Based on latest kernel sources from Google, Kernel is made for Android 12
    - Linux-Stable-Upstream included to 5.10.113
    - Compiled with prebuilt Google clang 14.0.5
    - merged kernel/common (improvements to android-common-kernel straight from google)
    - Multi-gen LRU backported (more info here, here as well and here) to improve mm and reduce cpu cycles
    - Utilize an additional kswapd thread to increase throughput for memory reclaim
    - 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)
    - 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
    - improve trusty driver performance which connects to fingerprintscanner-hal by using high perf wq during fp unlock
    - restrict maximum CPU-Freqs during screen off/ idle to 1.1GHZ for all clusters to save power
    - introduce unfair f2fs rwsems to prevent writer starvation and improve IO perf under heavy load
    - fuse: give wakeup hints to scheduler to speed up compress/decompress in internal storage (details)
    - enable RCU_BOOST (details here), also fix RCU_BOOST behaviour
    - F2FS-Stable updated
    - TCP backports from mainline
    - BFQ updates backported from mainline
    - use bbr as default TCP congestion algorithm (fasted algo according to this excellent research from @kdrag0n found here )
    - Enable support for TTL spoofing
    - Include LRNG, see here and here for more info (thanks @arter97 for the work on his op9 kernel)
    - important patches from kernel/common for 5.10 (here are more details)
    - 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)
    - dirty pipe exploit fixed
    - supports direct usb access for hi-res playback over USB-C DACs
    - flashing the kernel will preserve root

    Various Optimizations:
    - update several drivers to use power efficient workingqueues (for example wlan driver)
    - kernfs: use buffer from the stack space
    - printk: use buffer from the stack space
    - kthread: use buffer from the stack space
    - bpf: avoid dynamic memory allocation for small value buffers
    - binder: Reserve caches for small, high-frequency memory allocations
    - kernfs: use kmem_cache pool for struct kernfs_open_node/file
    - cgroup: use kmem_cache pool for struct cgrp_cset_link
    - f2fs: reduce timeout for uncongestion

    - restrict little cluster to 1,19ghz mid cluster to 1,19ghz and big cluster to 1,1ghz during screen off, to reduce battery usage for example during music playback
    - tie pelt multiplier into the powerhal (more info here)
    - prevent frequency spikes caused by small transient tasks during idle operation (more info here)
    - boost scheduler using the pelt multiplier during fingerprint unlock operation

    Build for Android 12 QPR Beta: https://forum.xda-developers.com/t/...pixel-6-pro-aka-raviole.4358435/post-86857033

    Requirements

    - 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, magisk 24303 and higher will bootloop on QPR beta and might act up on stable A12.1.0 too!)


    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)
    (if you´re for whatever reason on November firmware -> use 1.3.0! More recent kernel releases will bootloop)
    2. Flash the correct kernel.zip via EXKM or FKM. 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 without relying on paid apps like fkm/exkm:
    Please have a look at the linked post.

    Update to 1.8.4

    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!


    Changelog:
    - linux-stable 5.10.103
    - contains fix for the dirty pipe exploit
    - built with clang 14.0.2 prebuilt by google
    - improvments from kernel/common
    - fix memory leaks
    - security related patches
    - mm improvments
    - f2fs fixes
    - scheduler fixes
    - for details please check github
    - built with improvements from A13 Dev Preview to display driver
    - other changes please look at my github

    Update to 1.7.0

    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.
    Updated instructions in the OP!


    Changelog:
    - February Security update merged
    - linux-stable 5.10.96
    - include latest f2fs-stable
    - improvments from kernel/common
    - fix memory leaks
    - security related patches
    - mm improvments
    - for details please check github
    - introduce unfair f2fs rwsems to prevent writer starvation and improve IO perf
    - update patchset to prevent freq spikes caused by small transient tasks (also tie this into powerhal)
    - give pelt multiplier power hint for scheduler performance boost during fingerprint unlock
    - fuse: give wakeup hints to scheduler to speed up compress/decompress in internal storage (details)
    - enable RCU_BOOST (details here), also fix RCU_BOOST behaviour
    - update LRNG implementation (thanks to arter97 )

    Update to 2.1.0

    Hey guys and girls,


    Alright here´s the next update. And it´s again a really big update! :)
    A few weeks ago google pushed a backport of Multi-Gen LRU for the 5.15 kernel to their aosp/kernel common branches. I went ahead and backported that to our 5.10 tree alongside other mm-improvements from linux-mainline. By now google pushed their own backport for 5.10, but I decided to go with my original implementation as it contains a lot more improvements alongside the main Multi-Gen LRU backport and ran stable for well over 3 weeks.

    Powerhal was adjusted quite significantly too. CPU-freqs are restricted to 1.1GHZ max during screen off/device idle operations to save more power. App launches and camera operation are improved as well in the powerhal. General usage benefits from those changes too.

    Latest linux-stable, f2fs-stable and kernel/common were merged as well.

    Users that decide to not use the CleanSlate features and don´t install the apps won´t see the kernel parsing for the config files extensively.
    Vibration Booster from CleanSlate was improved as well to kind of counter the weaker haptic feedback since the March update. Please check the linked thread from the changelog. Huge thanks to @tbalden for this. If you want to give a little bit back consider purchasing the apps via playstore or maybe a small donation. :)



    I´ll keep the warning as to preferably using magisk stable to avoid potential issues as well here in this post.
    Please note that 24305 works fine for me though on non beta, stable April firmware!
    Important:
    Make sure you´re being rooted with magisk 24300 stable before flashing the kernel if you´re unsure. Any magisk version above 24303 might potentially lead to a reboot back to bootloader since android 12.1.0 and A12L QPR3 Beta. At the moment this only affects canary, but I put the warning just in case this will not get resolved in upstream magisk in time until the next stable drops. I saw a post that some modules also have problems with latest canary, so there´s a lot going on at magisk´s side at the moment.
    A post containing a short write-up how to "downgrade" magisk can be found following this link.



    Changelog:

    - Update for April Source
    - Linux-stable merged to 5.10.109
    - f2fs-stable merged
    - fixes and improvements from kernel/common including several subsystems
    - multi-gen LRU ( more info here, here as well and here)
    - general LRU improvements from Linux-Mainline
    - improve camera performance by tuning the powerhal during recording
    - improve app launches via powerhal
    - restrict maximum CPU-Freqs during screen off/ idle to 1.1GHZ for all clusters to save power
    - remove cleanslate config files getting parsed excessively even if user did not install the CleanSlate apps
    - improve vibration boosting feature in CleanSlate config app to allow stronger vibration again(please have a look at this post )
    - other fixes for CleanSlate features such as sweep to sleep
    - updated anykernel 3 zip, thanks to @osm0sis
    - probably a lot more I forgot as time is short for me.

    Update to 2.4.0

    Hey guys and girls,


    Alright here´s the next update and it´s fine to flash on May firmware. As I suspected we already had all the changes for May by merging upstream.
    I´ll include the changelog from 2.3.0 as well in this release post, since I think a lot of people flash the kernel on a monthly basis when the security updates drop. So this post pictures the changes going from 2.1.0 to 2.3.0! As I said 2.3.0 was kind of a final rehearsal to make sure everything is good for the May update.
    I´ll put a remark behind changes going from 2.3.0 to 2.4.0.
    This release is made for stable Android 12.1.0 May firmware. Not QPR Beta or A13 Beta!
    Once I find enough time or QPR beta gets updated, I might update the QPR beta release. No plans to support A13 beta.

    I also finished up the tables/graphs in regards to different binnings with the respective voltages on different tensor chips thanks to the dmesgs you all provided. I really want to put out a big thanks here to everyone for taking the time and participating. It was really great to see this kind of response.
    I´ll provide them in a post in this thread soon.
    So with that in mind we´ll get to the next paragraph were I could put those tables to good use.

    A few changes from A13 Beta are merged to the kernel so we can enjoy the improvements on A12 ahead of time. Most of them aim to improve the scheduler and task placement.

    However the recently dropped A13 Beta source contains a commit that can restrict max-cpufreqs based on PMU (Power monitor unit) reading. I setup this mechanism (lets call it "PMU Limiter") to mildly cut back max-freqs when they aren´t needed. It works quite well so far, with no performance impacts during scenarios where max cpufreq is beneficial. (e.g. app launching, camera launching, interaction etcetc)
    That means if a certain threshold is not crossed the max-freqs will be restricted to 1,4GHZ/1,6GHZ/2,4GHZ (for little/mid/big cores). As soon as the PMU detects enough pressure, those limits will be lifted.
    The frequency limits are based on tracing during various scenarios, benchmarking and also factor in the voltage table I was able to create. For example: 2.4GHZ for the big cores is the last freq step where a steady linear increase in voltage can be seen. Freq steps higher than 2,4ghz have a steeper slope.
    Keep in mind CPU-Freqs shouldn´t be touched in EXKM/FKM or other kernel managers. They are controlled by various mechanisms now (thermal hal, powerhal, pmu limiter etc) and values will get overwritten based on input.
    That means if you open the CPU section in a kernel manager, the maxfreqs will not be the actual maxfreqs that are possible. or the minfreqs might be raised. That´s normal and there´s nothing wrong if that´s the case.

    Additionally to the previous changes tasks of rt, sf and ta groups are now biased to start on high capacity CPUs during app launches, interactions etc.
    As usual, depending on your usage you may or may not notice a difference during these scenarios. :)

    While tracing I noticed kswapd often takes 100% cpu share when reclamation is happening. Since we use an 8 core cpu, an additional kswapd thread is being spawned during boot, which increases throughput for kswapd in these scenarios. Reasoning behind this can be found here.

    The trusty driver which connects to the fingerprintreader hal uses now a high prio workqueue when the phone is unlocked via fingerprint scanner. This means better performance, especially under stress. Keep in mind this is a kernel level change, it won´t magically improve fingerprint reader times manifold.

    DAMON and DAMON-Reclaim were removed from 2.3.0 going to 2.4.0. I tested the feature privately and it unfortunately collides with googles EH zram implementation causing the phone to crash at the moment. Tried to debug this issue, but no luck for the May release here.
    If you previously enabled the feature without adjusting the parameters properly and your phone didn´t crash, DAMON-Reclaim just didn´t do anything.

    2.4.0 also has an updated anykernel3.zip, which includes all the latest anykernel3 changes.
    Thanks to @capntrips we now have full support to resize vendor_dlkm partition which is part of the super partition. That means we finally can flash larger than stock vendor_dlkm partitions via anykernel3.zips and resize the partition properly instead of just dd´ing to it.
    A huge thanks to @capntrips for working on this and to @osm0sis for maintaining anykernel3.


    Disclaimer:
    I´ll keep the warning as to preferably using magisk stable to avoid potential issues as well here in this post.
    Please note that 24306 works fine for me though on non beta, stable May firmware!

    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.
