Hi @Lord Boeffla, facing a small issue with the boeffla config app since its last update. I get this notification of the app that comes up in my notification panel (see attached screenshot) even though i have disabled the notification but going into the app Settings > Background Activities > and enabled the Avoid service notification (i use that battery stats thing which requires a service of boeffla config app to run in background)

Can you please check this out :)

Have you restarted your phone afterwards already?

And can you post a screenshot of your background settings please?

I am currently in Hamburg till Monday. But will check mid next week then.

Yes i have restarted the phone multiple times, this is happening from nearly a week but i thought that you might know about it and maybe its a bug in the app.

Here is a screenshot

@Lord Boeffla @aviraxp
does any one of you just have the commit ready to make off screen gestures work on aosp/CAF based roms (namely aosip)? would like to recompile (i'd also share the kernel if you see any point in it) :)

I never had such a commit in my repos. But I never worked with AOSP or CAF.
On the OP2 I never had to fix that, only starting from OP3 onwards.

Yeah, i couldn't find anything related to this anywhere yet (probably wasn't searching hard enough).

I'll see if i find anything useful in op3 kernel repo (its rom related and therefore probably similar changes).

Thanks anyways

Latest kernel still compatible with latest version of LineageOS?

Yes, indeed. Last code change for the kernel in the LineageOS code repo is from 26th of December 17.
(https://github.com/LineageOS/android_kernel_oneplus_msm8994/commits/cm-14.1)

Looks pretty much as CM-14.1 is almost dead on the OP2 meanwhile.
And LineageOS 15.x is not yet there (and I will not work on a LOS15 kernel anyways anymore, 2.5 years of support for a device is enough, was a long time).

Rest in Peace Boeffla for the OnePlus 2.

(Currently using OP5T) just lucky to see you there :)

Hi all,

probably one of the last maintenance updates of that kernel:

Version 6.1-beta20
19.03.2018
  • Important: I meanwhile advice to switch ext4 tweaks and dynamic fsync to off for optimal data integrity. Use these two options on own risk.
  • Change: Internal kernel busybox updated to latest version 1.28.1 (self-compiled from sources, www.busybox.net)
  • Fix: KCAL sys interface changed to allow apps to better detect it (e.g. cf.lumen)
  • Fix: Fixed a typo in bccontroller script
Enjoy

    Hi all,

    some of you know me from the other OnePlus (One and X) or Samsung devices areas, where I provide my kernels already for more than two years to OnePlus One, OnePlus Two, Galaxy S5, S3 and Note 10.1 users for all sort of platforms (Samsung, LineageOS, Cyanogenmod, Omnirom etc.)

    Please note:
    I am not heading to have as many features as possible implemented, this is not my design goal. If you are more into that, move on to other kernels. If you are searching for a good mix of improvements and new functions while not sacrificing stability, you are welcome here (see below the history section for more info).

    Important notes

    When using new anykernel concept Boeffla-Kernel: Flash stock kernel of rom first !

    Make sure you flash the correct kernel version, depending on whether you really use LineageOS/CM or a different OS !!!

    Also note: You have to use Boeffla-Config app which I provide on my homepage to tweak the kernel. 3rd party apps will not be able to unleash the full power of the kernel.


    Compatibility

    Important: This kernel is only meant to be compatible with official LineageOS and nothing else.
    It is reported to NOT work fine specifically on Resurrection Remix roms, also some Seraph based roms are not compatible.

    So when the kernel does not run on custom rom XYZ, do not even bother me with it or ask hundred times in the thread for compatibility.
    I could not care less about it !!



    Support

    First read the FAQ section on the Homepage !!!

    Click here to learn about all possible kernel settings in the config app (quite outdated, as it is focused on S3 still).
    Click here to learn about using the config app (quite outdated, as it is focused on S3 still).

    I will refuse to give support if you do any undervolting and experience freezes or hot reboots.

    I will also not provide any support if you do not use Boeffla-Config app to tweak the kernel, other 3rd party tweaking apps are known (and intended) to cause issues.

    I will refuse to give support if you have xposed framework installed and reporting any kind of weird issues. My opinion to xposed it quite clear: too powerful for >90% of the users that just mess up their system with it.

    Otherwise, you can get in touch with me via the support e-mail address: [email protected]

    Please provide kernel version, rom version, a detailed issue description and ideally supporting screenshots or log files.


    Change logs

    (you can also access them directly in Boeffla-Config V2 by pressing menu and selecting "change log...")

    History and design targets

    Basically I created my first Boeffla-Kernel in 2012 as there was no kernel for the Samsung Galaxy S3 around that had exactly the mix of functionalities that I wanted. I wanted to have full flexibility in undervolting and charge rates for instance, but did not like the sharpness and/or brightness tweaks many kernels have implemented as per default.

    Hence, I began to create my own kernel after a while, adding all the features I like. This is the result of my work, which in the end I decided to share with you. I hope you like it as much as I do.

    The objective of this kernel is to have a kernel for daily use. It does not aim for best battery life, or best smoothness or best benchmark scores. Also it does not aim to have the broadest feature set available everywhere.
    It aims more for a good mix of all, not sacrificing stability and functionality in the end.
    And - most important: It aims to stay quite close to stock !!!

    These design targets are also valid for the OnePlus kernel here!!!

    This said, I will definitely NEVER implement:

    • things I do personally not need
    • things I do not like
    • things that are in any way dangerous
    • anything which is highly experimental
    • f2fs - it is known to cause various issues and compatibility problems
    • custom hotplugging algorithms
    • a CAF based kernel
    • anything that requires upstreaming of kernel parts to a higher kernel major version
    So do not even ask for it if it falls into the listed categories. Everything else I am happy to check and decide.

    And: I do not really care about benchmark numbers, they say almost nothing as long as something is not completely wrong. Important for me is the feel-good factor.
    I am also not interested in gaming at all, so never expect a gamer kernel. It will just not happen...


    Compatibility

    To reiterate it again: Flash the correct kernel depending on whether you are using LineageOS/CM or another rom !!!


    Configuration of the kernel

    To tweak and configure the kernel, manually load and install the app "Boeffla-Config V2" from the downloads section on www.boeffla.de.

    You need at least version 2.4.50 or higher for the OnePlus 2 Boeffla Kernels.

    Donation

    If you donate at least 2,49 EUR (to be in line with the donation app prices on Google Play store), you will receive a personal donation code which unlocks some nice little comfort functions in Boeffla-Config V2 on top.


    Source code

    All sources can be found in my Github repository: http://github.com/andip71


    Credits to developers

    Of course, I had never been able to create all that by my own. So I want to give credits to the really good developers around, that have given me all the inspiration and from which I cherry picked lots of the implemented functionalities:

    * ZaneZam
    * flar2
    * Grarak
    * Yank555
    * Hardcore
    * Chainfire
    * AndreiLux
    * Netarchy
    * Gokhanmoral
    * Simone201
    * Mialwe
    * Entropy512
    * Faux
    * Harunjo
    * FranciscoFranco
    * Ak

    ... I just hope I did not forget someone. If so, please let me know and I will add you of course.
    Thanks to all of you for your great work !!!

    Disclaimer

    *** As always - Flash on our own risk! ***

    Make sure you flash the correct version depending on your firmware version!

    I can and will not take any responsibility for bricked phones or lost data.

    It is generally recommended to run a complete Nandroid backup in your custom recovery and safely store your personal data before you flash a new kernel.


    Cheers and enjoy

    Hi all,

    new things are coming up soon, I will change the complete concept of Boeffla-Kernel during start phase very soon (yes, I will move on to anykernel method).

    Hence, I release my kernels now as last stable releases following still the old concept (static ramdisk method).

    Version 5.0 stable
    04.07.2016

    • Note: This is the last version of this Boeffla-Kernel which comes with a static ramfisk.
      New kernel versions will work with a completely new concept (anykernel method).
    • Note: Only use this version on official CM13 nightlies
    • Note: You need at least version 2.2.51 of Boeffla-Config V2 to allow all functionalities to be available
    • Fix: Big CPU cluster hotplugging profile "min=2, max=4 (default)" fixed to not switch off cores when certain apps (i.e. camera) are started
    • Update: Ramdisk of official CM13.0 build of 04.07.16
    Enjoy

    Anykernel arrived

    Hi all,

    it is time for the first CM13 kernel with the new anykernel concept.

    Before you start, make sure you have read and understood the following:
    http://boeffla-kernel.de/index.php/7...new-anykernels

    If you ask questions which are addressed in this article, or you have issues which are a consequence of not reading the article, I will not answer. It is your responsibility to understand what you do BEFORE you do it.

    (and also read this for more background: http://boeffla-kernel.de/index.php/6...ernels-new-app)

    Side note:
    Although the kernel is now likely to be much more compatible with custom roms using CM basis, I will not change my support conditions at all. If you report an issue on a non-original CM rom, do not expect me to react (http://boeffla-kernel.de/index.php/support/support)

    Ensure you update to latest Boeffla-Config App 2.3.1 BEFORE you flash the new kernel !!!

    Enough threatening now, here we go:

    Version 5.1-beta1
    12.07.2016

    • Note: This is the first Boeffla-Kernel with the new anykernel concept.
      Make sure you read and understand the basics: Boeffla-Anykernel Know-How and New concept kernels/New app

    • Note: You have to use Boeffla-Config version 2.3.1 or newer in order to use all functionality !!
    • This kernel as exactly the same functionalities as the last stable kernel release
    Enjoy

    • Fix: Rare CPU scaling issues fixed
    Enjoy
    Andi

    P.S. Thread remains closed.

    Looking good so far...

    Hi all,

    I might release beta1 for official CM13 still today.

    So far testing is looking good.

    Screenshot attached.
