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.
ok, but ROMs with ROM based stock must have maximum android 6, ROMs with nougat, oreo and pie are not supported by the kernel, right?

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

The development stopped for this about a year ago

Lol, and what is the reason why you think the developer stopped at Nougut lol. Get off the US sites and find the really good ones open to the public.

/* 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.

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.

Does anyone else have any idea why spotify stops playing after several seconds after screen is off? I ticked it off to not optimize battery usage for it, it still does it. @arter97 any ideas on what I need to change? I tried bumping up the minimum frequency but it does not help. Thanks!

    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.

    c6ec07acba126c1a11b63a95c385b845095fbad9a74de2e8168637dcbe28ede2.jpg


    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).

    Revamped CPU governor to fix misc issues due to improper merges
    ren_max_freq renamed to scaling_max_freq to fix apps like Kernel Aduitor
