Just out curiosity, which error does it give everytime in kmsg?

It's not everytime the same error, but similar. But it think it's just one bug.

Code:

I'm not very skilled at Linux memory management.
It's very low-level stuff.
I do suspect it has something to do with the movable pages or virtual memory.
There is a little mess ...
Samsung partially added patches from newer kernels for movable pages for the stock driver zSwap, but not for zRam. Now we want to use zRam, because it's faster. Another problem is, there is no proper documentation about added patches on top (commits). And this makes it very hard to track bugs. Also it's hard to upstream this kernel. Because most of the patches would just fail, due to some patches already applied and so on. Same problem for device specif patches, no commits at all. Samsung did that mess on Galaxy Ace 2 and i was hoping they would do a more cleaner job on Galaxy S8, but the same mess here.

If kernel source were clean like official Android kernel source, and just added device specif patches on top, even without proper commits messages, it would be possible to filter out device specific patches, and then simply adding that patch on top of latest Android kernel. Then we never had stability issues. But well, we will fix it anyway.

Uploaded new test kernel .. disabled

Code:
CONFIG_ZRAM_MIGRATION_SUPPORT
and
CONFIG_MALI_DMA_FENCE

Bsically CONFIG_MALI_DMA_FENCE is disabled in stock kernel, don't know why Samsung didn't enabled it, since it compiles fine without any error.
And CONFIG_ZRAM_MIGRATION_SUPPORT was originally enabled for zSwap, but adapted from me to work with zRam too. So disabled, maybe i did some mistake here.

Both are optimizations for better performance, maybe one of them is a culprit.

And there are further 2 optimizations that i suspect that it could make also problems .. but we will disable them in next test build if still unstable. After that. i'm out of ideas.

Those 2:

Code:
CONFIG_RBIN
CONFIG_ION_RBIN_HEAP

Report dev exprience using test kernel 30 november i had some lag that stuck for a while come smooth for while too when open facebook whatsapp and other social media apps for other apps game and other almost same problem but no more then 1 second in social media apps it took 3 or 5 sometime
To day i will test new test kernel

    I've tested the following flags and they works very well:

    Code:
    dalvik.vm.usejitprofiles=false
    pm.dexopt.first-boot=quicken
    pm.dexopt.boot=quicken
    pm.dexopt.install=speed
    pm.dexopt.bg-dexopt=speed
    pm.dexopt.ab-ota=quicken
    pm.dexopt.inactive=speed
    pm.dexopt.shared=speed

    This will be the new default in next build.

    Alright time to release the 22.01.16 official & pre1 and pre2 kernel builds with new default.prop variables what @ace2nutzer tested with and worked very well. thanks for looking and testing :)

    if there issues ex with the flashable zips or getting random reboots let me know, anyway all three are tested and should work on your devices without issues guys :)

    @Ryujin96 When I get to the ''unpacking'' part in android kitchen this error happens. Do you know what it could be?
    Tbh i dont know😅 can be the file is corrupy or something?😅

    I did the procedure in another way. I downloaded ES FILE EXPLORER, gave root permission, went to the "default.prop" directory and made the changes you mentioned. I don't have that slowness anymore. It looks like it worked like that. I didn't change the "First" or the "boot", I was in doubt if I should. @Ryujin96
    Hmm, tbh i dont think it worked becus the file gets replaced with the one out of the /boot partition when you reboot the phone. Only way to change it is to flash a boot.img with a editted default.prop. anyway i attached a editted a2n kernel with a editted prop inside. If you get issues just flash the a2n kernel from ace his ftp😊
    1
    Tbh eu não sei 😅 pode ser o arquivo está corrompido ou algo assim?😅


    Hmm, tbh eu não acho que funcionou porque o arquivo é substituído por um da partição /boot quando você reinicializa o telefone. A única maneira de alterá-lo é atualizar um boot.img com um default.prop editado. de qualquer forma eu anexei um kernel a2n editado com um prop editado dentro. Se você tiver problemas, apenas atualize o kernel a2n de ace seu ftp😊
    Could you make the official version 16.01? It's the most stable and best on my phone.

    New build is up !!

    Changelog

    Kernel V. 2022.01.10

    • Improved stability
    • CPU: updated HMP driver
    • Optimized MIF & INT Freqs qos-requirements
    • Removed F2FS driver
    • Uploaded also patched TWRP with this release inside
    Release notes:
    Please consider new installation method from post #1.
    Also it's highly recommended to flash AdAway_hosts_patcher_g95x.zip to hide ads in almost all apps and web-browser. Especially if you are using AdAway app or you had already patched "/system/etc/hosts" then you should flash the patched AdAway_hosts_patcher_g95x.zip in order to fix potentially logcat spamming, because recently official AdAway hosts sources is buggy. Otherwise it causes high CPU load and battery draining. Later once it's fixed then you can use official AdAway hosts sources like usual.

    Idk why ppl need secure folder on their phone, kinda useless
    it's very private issue you know.. lmao.. they need to hide study materials in there
    3
    There is a bug in HMP driver.
    It'll be fixed in next build.
    Workaround: close all apps, also remove all apps from recently used apps, just before you turn the screen off.

    My first impression on the new kernel (20/12) is just smoother and working better than before. and I love it!
    Actually I have been using this kernel since 2020 or maybe 2019 and there are lots of improvement so far. I would say this is the best kernel for exynos s8. thank you for the hard work!
    3
    Just wait for new build. I don't need logs for now.

    FAQ

    Q: With which ROMs this Kernel is 100 % Compatible ?
    A: Currently only with Samsung stock ROM (Android 9)

    Q: How to bypass SafetyNet ?
    A: Anable MagiskHide in Magisk app.

    Q: How i can Tune this Kernel ??
    A: Everytime you install or update this kernel you will face an red (demo) app "A2N Kernel Control..." open this app, and it'll redirect you to Google Play to get the full version (blue app).

    Q: Can i use and Tune your Kernel with other Kernel Manager Apps ?
    A: No.

    Q: I've Installed the Full Version of the App, Will it Change any Kernel Settings by Default if i do not Change them ?
    A: No, default app settings = default kernel settings.

    Q: I've the Full Version of the A2N Kernel Control App, Do i still need the Demo Version of the App ?
    A: Yes, there are some special features in-app-menu like "Fake Enforce" and debugging features for easy bug reports.

    Q: How to Charge from 10 % to 100 % In just 1 h ?
    A: E.g. set "AC Current Max" and "Maximum Charging Temperature" to the Max.

    Q: How to get Max Speed for e.g. Highest FPS in Games ?
    A: Set BIG / LITTLE CPU and GPU Freq to the Max, but avoid to use "unsafe" Freq's.
    Then set CPU / GPU --> DVFS --> "Maximum Temperature" to the Max.
    Now you can even cook an egg on your phone !

    Q: Will my Custom A2N Settings Survive if i install Stock Kernel and then going back to A2N Kernel ?
    A: Yes, as long as you don't uninstall it.

    Q: Can i use your Kernel Control App with other Custom Kernels ?
    A: No.

    Q: How to Report Bugs ?
    - Please DO NOT report bugs if you are:

    --- using "unsafe" Freqs
    --- not using the latest release !
    --- not using Samsung stock ROM (based stock ROMs are custom ROMs !)

    A: Open the red A2N Kernel Control demo app and check in-app-menu (3 dots) then "Debug" and then on "logcat and dmesg" if you faced an app crash or if some features didn't work.
    If the phone rebooted randomly, then tap on "last_kmsg". You will find the logs in your internal storage. After that you can attach them here in your bug report, by clicking "Attach files".
