An Update to BTTF

Hello,
Somebody asked about getting an updated nougat kernel.
I wasn't sure about doing it, but I looked at the mk2k-elsa branch
(which I hadn't touched since november 2018) and there I noticed
a bug!
Something I did wrong and later fixed in my other kernel, but forgot
about here. Well, I guess that's why when those few hardcore Nougat
tweakers mention BTTF, they say "BTTF-BETA1" and not "BTTF" as in the
final release. Because that's where the bug was introduced... darn.

Ok then, that prompted me to fix it, but couldn't simply fix that little
thing and nothing else, so I did all this:

* K-Lapse 5.0
* WireGuard updated
* Supports more variants. F800K/L/S H990DS/SS
* Enhance I/O latency - drop CFQ and LG scheduler code
* Drop blu_active, update interactive and use new settings
* Compile with GCC 9 - updates and fixes to make it compile
* Enabled Darkness and Nightmare governors (forgot previously)
* Disabled a little extra bloat without being too much off of stock

LINK: BTTF-BETA2
It's called beta2 just to be safe, not expecting any problems. Probably will be final release.

Has anyone tried this yet? And can you share your settings? Thanks

Using h910 and just updated from beta 34 to 38 and it is running alot cooler, also noticed battery is better for me now than it was in 34. I've been loving your kernel for the past few months, thank you very much for all the hard work you're putting into this device :)!

Maybe, not sure. In my second post I recommend using latest firmware, since the beginning.

Updated to @jl10101 's 20B repack. All good now.

PS- GPU min freq is at 214MHz, doest wanna go to 133. Not a major issue though.

---------- Post added at 03:34 AM ---------- Previous post was at 03:32 AM ----------

Me too. Battery under 40% always stops my Poweramp music player. Very bad ram management. Is it fine to flash previous older kernel?

Update to 20B and it will be sorted. Just remember to back up firmware and efs folders from Oreo 20A and restore after flashing 20B otherwise you will lose the second sim

I keep getting an error / failed on BTTF-BETA2 for Nougat.

Latest beta is the best so far ty.

Any chance of adreno idler as a gpu governor?

Adreno-Idler is not a governor. It's not something you actually want either, that's all xda myth and hearsay spread among those who have
no idea what they're talking about. It's a modification to the adreno-tz governor, supposed to increase battery-life by fixing some inherent
bad behaviour.
It's old stuff, not applicable anymore. Any respectable kernel dev does not apply such things to modern kernels. Hopefully we can have an
end to such misguided desires causing much annoyance and spam in many threads.

I'm sorry I wasn't aware that was the case.

Thank you for this. Might have been me that asked awhile ago. I do remember asking about governors awhile back, glad to see it had some added :).

Well I ran into install error as well. On older TWRP also. 3.2.3.? I think lol. Anyway. Could be just a bad zipping of file (happens to me sometimes). Could you possibly try to fix and repost. Thank you again. LS997 btw.

    Download: Oreo V20 Folder
    The (AnyKernel2) flashable zip will flash kernel as well as /system/lib/modules. If you want to go back you should backup modules as well

    Notice: I don't own a V20, thus I can't guarantee it will be a sane and bug-free kernel for V20 users.

    Oreo mk2000 v2.0 BETA
    ^This is the link^


    * Linux 3.18.126 (latest)
    * Many interesting commits from sultan's and nathanchance's Pixel 2 kernels.
    * Replaced Input Boost with Pixel2 version. Now boosts on app launch (and on waking).
    * Also I've disabled normal boosting on touch input. No user configuration to be done.
    * Removal of deprecated code from KGSL (adreno) driver, by Sultanxda.
    * Various stuff...


    Ok so I've gone back to the beginning and refreshed the whole kernel. Starting with CAF base and
    merging in Android stable 3.18.126
    Then extracting (almost) all of the non-LG commits applied - separating them as individual commits, and
    finally applying LG's own modifications.
    After this I picked in from previous mk2000-oreo branch, condensing commits and omitting questionable ones.
    Of course upstreaming from 3.18.71 to 126 has brought a whole bunch of updates and fixes treewide.

    I removed sultan's irq and kthread management as that seems to not be plug'n play with the 3.18 kernel.

    I have been testing a bit myself and seems alright so far.

    Hey
    I updated first post with Oreo release info, and with (I hope to be) v1.0 stable release.
    This time every supported variant is there, even if they don't have oreo yet.
    24
    Questions

    Q: Will this work on newer bootloaders?
    A: It should. The kernel is based on the most recent of LG sources.

    Q: What control app do you suggest using?
    A: I suggest using SmartPack, or EX Kernel Manager.

    Q: I have US996, what version do I use?
    A: If you unlocked officially through LG then use "US996", otherwise use "US996Santa".

    Q: Where can I donate? I want to donate!!
    A: I don't accept donations because of two reasons. One: I don't really need it. Two: I like the idea of this being totally free, it adds to the enjoyability of the kernel.

    Q: I'm having some problems with kernel not working or booting?
    A: If you are on an older bootloader then that is likely why. My kernel works on new firmware, not exactly sure how far back the compatibility goes.

    Q: I flashed this zip in recovery, but it didn't seem to work, I'm still on my old kernel. What can I do?
    A: With AnyKernel you shouldn't need to re-flash ROOT after flashing kernel (if already installed, if not, do it before flashing kernel). SuperSu has been known to revert the kernel install if you do so.

    Q: OK so I just rooted my phone and installed this, and OMGOSH! so excited, now what do I do - do I tweake-dy freak out huh huh? How do I do it??
    A: Put simply, don't do anything. I don't know how things where in the past, but now you don't need to do anything. Not with this kernel anyhow. Such thing are better discussed in a separate thread anyway.
    23
    Version 1.5.5 BETA

    UPDATE: Added 1.5.5 BETA16 (With WireGuard)
    BETA16 can be found HERE

    NB: If going back to 1.4 after this, restore boot backup first to a point before installing 1.5.5 (or preferably start with fresh stock boot).

    Notice: As this is AnyKernel, it uses your existing ramdisk, so if you come from a different custom kernel you should probably restore a backup to stock boot before flashing my kernel. In that case don't forget to flash Magisk if your backup doesn't include that.

    External DAC: You likely must use a USB hub between your phone and dac for it to work.
