Works in Android Nougat? (7.0)

---------- Post added at 11:00 AM ---------- Previous post was at 10:59 AM ----------

I have problem with lags. Sometimes my phone lagging very much, and I checking kernel settings, And all small cores are on 400mhz and big cores 800mhz, frequency not changing even I using a lot of apps.. My governor is: interactive, when frequency changing value 400-1500mhz and 800-2100mhz phone working very fast and smooth, but sometimes is only 400/800mhz all the time without reason and lagging. I haven't idea help plz :(

Try to change governor.

No isn't abandoned, just read few last page's of N0G33K thread. Is still released but only on his Telegram Group which link you found in first post N0G33K thread. Look my signature, i'm using V7.0 RC6 and last on XDA is V4. Is just no more publicated on XDA...
I was talking about arter97's kernel, last version is 22, and it was released 13 months ago. Since then author switched S6 to OnePlus devices and stopped support of this kernel.

I have updated to magisk 15.1 and my battery is draining from deep sleep I think

I reinstalled the kernel and lose magisk so I do the whole operation again and same thing battery drain

Any sugesstions

Hi everyone

I am running Samsung s6 edge, on firmware 6.0.1 using artar97 kernel and xtrestolite ROM also with magisk 16 passing safety net

This might of been answered before I'm sorry for repeating

So I'm sure everyone is aware of this deep sleep fix, I have been searching for a fix, used to work with super super as they implemented in the app itself

Any module for magisk to help fix this issue or a anything I can do

Thank you for helping me

Apart from update to the latest firmware (7.0) good luck getting a reply with a fix. Your very behind in firmware terms.

please make for 7.0 Nougat
The development stopped for this about a year ago

Does this kernel support S7 flat battery?
Please stop spamming threads with this question and use your phone as is.

Any kernel supports any battery. I used stock kernel with 3600 mAh S7e battery without any issues for 6 months (and my mom still uses it). Battery calibration is automatic and takes ~1 week. Settings app will still reflect 2550 mAh capacity because this string is hardcoded in ROM (not even in kernel). But this number never ever is used by system.

Good evening,
sorry for ignorance. How do I understand with which ROM can work it?
Because he says that it's compatible with s6, ok, but if I put it for example a LineageOS, how can it work?

This kernel only supports Samsung Stock ROM. It may also work on other ROMs which are based on Stock ROM. LineageOS/AOSP/Cyanogen/any other open source ROM is not supported.

    /* Switch to f2fs */

    As mentioned above, this kernel fully supports f2fs.
    However, you are completely free to choose not to use f2fs.
    You can selectively convert partitions to f2fs using TWRP provided in the downloads.
    You should use the provided TWRP at all times after you switched to f2fs.

    /* Disclaimer */

    Your warranty is now void.
    I am not responsible for bricked devices, dead SD cards,
    thermonuclear war, or you getting fired because the alarm app failed. Please
    do some research if you have any concerns about features included in this kernel
    before flashing it! YOU are choosing to make these modifications, and if
    you point the finger at me for messing up your device, I will laugh at you. Hard. A lot.

    Give me some break here.
    I'm so tired of what's going on here.

    I'll re-open the thread after I finish testing 14.0 branch.

    Finally solved the massive memory leak issue.
    The culprit was on HMP scheduler, which I originally suspected the least likely place to durp.
    Version 13.0 and up has this issue.

    This issue was serious enough to make me consider retiring the kernel development altogether.
    Kernel stack was eating a whooping 700MB of RAM after about 72 hrs of uptime.

    I was drawing blank for 18 hrs, debugging and reverting hundreds of commits, then finally got the culprit commits on 5AM this morning.

    And to the CPU big cores frequency reduction issue:
    To those who don't know this dreadful issue, some race-conditions with user-space DVFS and kernel-space DVFS(yes, both) was causing big CPU cores' max frequency to stuck at some level.
    This obviously drops the performance to a noticeable level.
    This issue was present on Android 5.1 : it was getting stuck on 1704 MHz, and I workarounded it by renaming scaling_max_freq to ren_max_freq, which seems to work. But it also broke many CPU config applications such as Kernel Adiutor.
    Fast forward to today, I also noticed kernel-space was causing race condition. It was getting stuck on 1300 MHz, this time.
    This issue is less likely to be noticed with stock kernel since turning the screen off and back on will reset the frequency settings and set proper min/max frequencies for big CPU cores on the stock kernel.
    But because custom kernels like mine offers users to manually set the CPU frequency, we had to fix the aforementioned "reset frequency" stuff on stock kernel, but it also introduces an issue where because frequency don't get reset periodically, users are stuck with the particular frequency forever.

    I think I finally got a proper way to workaround this.
    Users' min/max frequency settings will be stored separately and it will be used as the reset frequency instead whenever screen goes off and back on.
    You will still notice this issue from time to time, if you're leaving the screen on for a very long time, but at least it would be much less noticeable.
    Not to mention, this will also solve the app compatibility issues such as Kernel Adiutor.

    I'll drop beta 10 within few days.

    1.0
    Initial release
    80
    Final to all those 14.0 tests/alphas/betas are up as version 20.0
    I was not able to reproduce any of the deadlocks on 20.0 for a week of usage.

    Why 20.0?
    Because 13.1 -> 14.0 doesn't seem that major.
    And I wanted to name it that way, damn it.


    I will now slowly retire from the Exynos 7420 development and prepare to switch to the OnePlus 3.
    Don't expect any new major feature(big perf/battery improvements).
    Minor bug fixes will be taking place for future versions(if there will be any).
