Custom lollipop kernel based on LG's stock sources. Currently works on D415/D410/D405 stock lollipop only.
Current Features:
Built with Linaro 4.9 optimized for cortex A7
intelliactive governor-build 2
-O3 optimization-build 2
interactive governor (google's gov.)-Build 3
Enabled OTG Support in menuconfig-Build 4
Patched Kernel source to 3.4.2-Build 4
Patched Kernel Source to 3.4.4 build 5
fixed version number in makefile build 5
Used Optimized version of square root algorithm build 5
Enabled Graphite Optimizations build 5
Other small optimizations build 5
Changed Default Scheduler to ROW-build 7
Changed governor to Interactive-build 7
Enable KSM-build 7
Some small mem leak fixes on gpio-Build 8
KSM now runs once every 50000ms instead of 500ms, but scans 200 pages instead of 100-build 8
Shrink highmem pages on kswapd-build 8 (ROM-Jeremy)
SOC Specific random number generation
Future Features:
New CPU/GPU governors
New I/O schedulers: request in the forum
possible OTG support
further optimization
Cyanogenmod support
Current bugs:
Since there are multiple versions of the D415, some versions might work better with this kernel than others.
If you are using a governor other than ondemand, LG's power saving feature will come mess things up, so turn it off.
Thanks to::
LG for providing kernel sources and updating to lollipop
Velosa for testing for D405
GrinningFerret for helping me download CM sources
ROM-Jeremy (I took some commits from his kernel)
Nikita Pro Android (I took some commits from his kernel)
The developers at the Moto G forum (their device is very similar to ours)

The fact that this has working OTG is actually great news!! Can't wait to see this on custom roms, good job!

To clarify, OTG is a planned feature in the future, it has not been implemented yet. However, I think there is a very good chance I can get OTG to work.

Anyway, that's what i mean. It is really useful sometimes.
It's very nice to see so many people working on L90 projects. It's a great device. Too bad there are so many hardware variants that makes it more difficult. The only thing I miss so far is OTG support. I hope you get it working.
I will gladly test it on D410hn if you need testers.

Is there a difference betwee this and the stock kernel ... Sorry for the dumb question

Currently, the only difference is that it is compiled with Linaro instead of gcc. Linaro is generally considered to be more optimized in than gcc, so theoretically the performance should be a little faster. The next build, which I will upload in a few hours, will include the interactivex governor, and -O3 optimization.
Aweosme thanks for the reply look forward to it
@zowpow
I'd like to test it but... I have d405n.
Only d415 currently
@OP
Was the compilation bugsfree?? For me it gives some errors (some file was missing), but maybe it depends on my custom GCC.
Or maybe it was because i compiled for D405n...

Do you remember exactly what the errors were?
Sent from my LG-D415 using XDA Free mobile app
Too bad - no. and i deleted all sources.
but i remember that other phones had the same errors
Edit: still don't remember the errors, but it was the fix for it (on xiaomi phones), but on our device it only lead to next errors:
https://github.com/MiCode/Xiaomi_Kernel_OpenSource/issues/3
Sorry for taking so long with the new build. But here it is (in the OP). If you test the new intelliactive governor, please play w/ the parameters and report back with the best parameters for the governor. Also, install custom recovery and back up /boot! Next builds will probably include more governors, new optimizations. I might try to add d410/d405 support in a few weeks when there are more features.
Build 3 uploaded
Build 3 uploaded. This build has the interactive governor. Make sure to backup /boot with recovery first! Also, if you plan on testing the intelliactive governor, play with some of the parameters and post the ones you find best. Flash these with RASHR or Flashify.
Also, interactive governor has much better battery life from my testing. I don't know about intelliactive though.
Do u plan on over clocking ?
Sure, I'll try to include that in my next build. The next build probably won't be ready until the Sunday though.
No rush man I'm just glad someone is making a kernel I would love to see what a little overclock can do on this phone
Just to let everyone here know, the msm8226 chipset has been hard locked to using stock frequencies. So even though it will say it is operating at an overclocked speed, multiple benchmark's proved it does absolutely nothing to performance. Until someone can figure out how to fix this issue, it's pointless for now. Just a heads up to the dev, and users

[EOL][KERNEL][UNOFFICIAL BUILDS] Boeffla Kernel Linaro/Uber
hi Guys,
It's me again and this time with a special "build-service" for boeffla kernel users! As some of them liked the "linaro build" made by Lord Boeffla in form of his 5.1 beta 13 version and requested it for newer versions too i decided to "tune" my build script a bit and spent that 2 min 40 sec in addition on every build for those of you who requested a Linaro build of recent versions of the boeffla kernel. As i anyway do my own builds of every new released (but only for samsung sources!) Boeffla Kernel version mainly for testing new versions of the ZZMoove Governor, building itself isn't that much more effort.
As stated Lord Boeffla used the linaro toolchain in his kernel version 5.1 beta 13 but he finally came back again to the well proven Android Stock Toolchain in following versions for stability reasons. Good and understandable decision because this is really what Boeffla stands for, stability and i underlined that *g*!! Kernel images build with linaro toolchain tend to be less stable then build with a stock toolchain due to the optimizations it makes to the code when it builds the image. Anyway they run a little bit "smoother/faster" and for some of you it even might not make any troubles at all. So in agreement with Lord Boeffla i want to provide you these self made linaro builds here for your further usage. Beside of that for really brave guys *g* i will in addition use this thread for own purposes too and will put in here beta versions of zzmoove governor compiled into boeffla kernel. But they will only be "Samsung" versions as i'm using only stock roms and they will only be build with stock toolchain because zzmoove is sometimes experimental enough, i have no need for more "unexpectedness" by using linaro toolchains during testing
ok then let's start...
First of all the obligatorily Disclaimer:
As also written in the title please note these builds are UNOFFICIAL, are NOT SUPPORTED in any way by Lord Boeffla or myself and might be EVEN UNSTABLE! So take them as they are! As always flash them at your own risk and make a backup before flashing!
About bugs: Before you report ANY issues with the linaro builds provided here (doesn't matter which one!) FIRST TRY the non-linaro official builds from HERE to see if they will be gone then. if they wont, you can go on and report your problems in the official boeffla kernel thread! I hope you understand that we have to treat and keep these builds here completely separate from official ones as they have in no terms something to do with each other! Not respecting this will force me to stop building further linaro builds of boeffla kernel.
About benchmarks and comparisons between toolchains: It's common known that linaro builds might give us higher benchmark rates and that seems great for some people (in fact it's pointless per se in my opinion ) so please if you really must, post them ONLY here and NOT in official boeffla kernel thread, thanks!
Now some more precise informations about what's going on here:
what i did:
the images are always build with original sources from official boeffla kernel repositories from HERE
with some not worth to mention minor changes to be able to build it on my build environment.
all images are compiled with following build flags which were also used in boeffla kernel 5.2 beta 4
and with NEW Toolchain Linaro 4.9.3-2015.03 - Credits to @Christopher83 for the preconfigured toolchain and many many thanks to @P$T for the pm with the info and credits for the needed modifications i could use from his repo! :highfive: meanwhile even @Lord Boeffla benefited also from this info and therefore we had also a stock toolchain 4.8 build
all images are build with lzma compression instead of gzip to produce a compatible images size with the used optimization flags below
Code:
-Wall -Wundef -Wstrict-prototypes -Wno-trigraphs
-fno-strict-aliasing -fno-common
-Werror-implicit-function-declaration
-Wno-format-security -Wno-array-bounds
-fno-delete-null-pointer-checks -fno-schedule-insns2 -ffast-math
-mtune=cortex-a9 -march=armv7-a -mcpu=cortex-a9 -mfpu=neon -marm
-fno-schedule-insns2 -mno-unaligned-access -fno-pic
ifdef CONFIG_CC_OPTIMIZE_FOR_SIZE
KBUILD_CFLAGS += -Os
else
KBUILD_CFLAGS += -Ofast -fmodulo-sched -fmodulo-sched-allow-regmoves -fno-tree-vectorize
endif
all images are build with changes from following repos:
Samsung i9300 Stock
https://github.com/zanezam/boeffla-kernel-samsung-s3
Samsung i9300 CM/LineageOS/Omnirom
https://github.com/zanezam/boeffla-kernel-cm-s3
https://github.com/zanezam/boeffla-kernel-omnirom-s3
Elite Boeffla Kernel:
https://github.com/zanezam/elite-boeffla-kernel-lineage14.1-i9300
Samsung n51x0 Stock
https://github.com/zanezam/boeffla-kernel-samsung-n51x0
Samsung n51x0 CM/LineageOS
https://github.com/zanezam/boeffla-kernel-cm-n51x0
what i will do:
build the source code with linaro toolchain and (like Lord Boeffla usually does) provide a odin-flashable tar.md5 and a CWM image of recent boeffla kernel versions.
do a test for about 1 day with this builds and if they work without any big issues, add them here in the thread.
i will try to keep the linaro toolchain as up-to-date as possible till the need of bigger code change will be reached.
not providing versions that are not released by Lord Boeffla yet.
not providing an image if it is not working - well of course not *g* but it will be marked as "canceled" then for info.
not change the source code to add/remove features or fix boeffla kernel related bugs.
not support the whole stuff here.
what i will maybe do (sooner or later):
provide zzmoove test builds if there are any new versions to test - more infos and discussions about ZZMoove Governor can be found HERE
maybe tune the build flags if some more linaro experienced user comes up with "better" ones (feel free to post and let me know, linaro specialists! *g*)

NOTE: if u got issues with root (cause is currently unknown!) after flashing one of these images u can try this method provided by @VictorLapin (thx for letting us know!)
previously known issues with recent boeffla kernel versions compiled with linaro toolchain (none of them appeared since one of newer toolchain 4.9.1 versions and also did not appear with actual used 4.9.2 version):
stuck of max. frequency for example at 1400mhz even if it is set to a higher max. frequency - reported by some users, and confirmed by me!
fix would be to temporary change the governor once or also temporary change the governor settings once (for example with profiles in boeffla config app)
EDIT: This is not related to the toolchain!
slower hotplug or sometimes stucking cores in zzmoove governor - reported by some users, not confirmed by me
higher "idle" temperature and operating temperature in general - confirmed by me
noticeable higher energy consumption (maybe related to next issue) - confirmed by me
lags when using zram and or in combination with frandom tweaks - confirmed by me
random hot reboots - confirmed by Lord Boeffla, not confirmed by me
see? that's really not boeffla like, isn't it!? but anyway as always these problems might depend "just" on one, some, or on a combination of multiple things so it might be that you never face them. If you find a setting and/or have other informations which workarounds or even fixes the issues feel free to post them here they would be highly appreciated! Even if this is not the main aim of that thread yet we maybe can find a way to a more stable linaro build of boeffla kernel and that would be a good thing, though! :highfive: Beside of that feel also free to post new issues found with the linaro builds but keep in mind don't forget to crosscheck with non-linaro offical builds to be sure that it is really related to the toolchain.
finally i wanna throw out big thanks to Lord Boeffla for his great work and for accepting that i provide you the linaro builds here especially because he had a bad feeling about this, but i think we will not disappoint him, won't we?!
enjoy living on the edge...

Version 5.2 beta 1 ready
Hi Guys,
just for info:
Boeffla-kernel-5.2-beta1-Samsung-i9300-linaro - build ok - testing
arriving in about a day (if everything is ok *g*)
EDIT: and looks good to me therefore added to the OP! enjoy!
regards
ZZ
fantastic !
Just want to say that I am using this kernel for about one week now and this is by far the smoothest kernel I have used. I really can feel the difference between Google Toolchain and linaro (Beofflas build is also smooth but I think this one is a tick faster). I don't have any of the problems mentioned in OP. Everything is working like it should.
@ZaneZam there is a new linaro build available - 14.01. I also see there are many devs using linaro 4.8.3. What is the difference compared to the linaro version 4.7.4 you are using?
Many thanks in advance.

Thx for the info! nice to hear that! :highfive: well honestly atm i dunno exactly what's the differnce between these two toolchains (but i think it might be a lot, question is if it has big relevance for us ) i have to check that in a quiet minute. but what i know since yesterday from my own experience is that recent boeffla kernel beta2 (inofficial yet, but will come soon) + zzmoove 0.8b10 (release candidate, comes also soon) build with linaro 4.8.3 runs very good!! if that positive result stays for one more day :fingers-crossed: i will jump on that one and forget the other one!
we will see...

hi guys,
sry to all of you who are waiting for the latest linaro build and still can't use it yet!
unfortunately this build delays a bit because of three reasons:
first: a dumb-ass "git" accident during prepare of sources - i really nuked my brand new build script - what a fu.... mess still can't beleve it
(for insiders: NEVER EVER do a "git clean -f -d" if you are in hurry or try to do mutli-tasking (last one applies not on girls *g*)! backup? what is this? needed? no yet! *g* yeah i hear u laughing insiders but i think some of u know exactly how this really feels if u have spend some hours for what u lost, actually so: :crying: well i will survive this but throws me back a bit. some of u might think: wtf? hours needed to a make a build script? well due to the latest motivation because of this thread here *g* it has grown up from a advanced script to a full automatic build programm
second: i have a "feeling" that Lord Boeffla will release a new beta soon!
third: day has too less hours (hence this giant automatic build "programm" *g*)
i'm just doing a dump of the latest changes i made from my brain into an older backup of the script
and will be back again if it is up and running and maybe also with new beta of boeffla kernel thenl! :good:
aaand yes as i said i did already a test with recent beta2 build with new linaro toolchain but this build has "something" included which is only for interenal testing yet. yeah u got me it has some final changes for the new "beast" included
so I ask for a little bit patience, thx!
cheers

Your "feeling" was absolutely right. Seems you got some insider information, hehe.
But now it is out, so go for it with Linaro
Thanks

This is a kernel for Cyanogen Mod 12.1, which is based on the EvoMix kernel by Alx31TLse, olivieer and SuperHanss (full credits to them). It is compiled by a Linaro 4.9.3 toolchain, which was optimized for Cortex A9 CPUs (thanks to Christopher83). It has a focus on stability, performance, endurance and overclock-ability (roughly in that order).
It uses the original ramdisk of the installed kernel (thanks to osm0sis), for maximum compatibly in the long run and instant adaptability to most source changes of CM. For now, it probably only works with the very latest unofficial CM12.1 built by qsnc (http://forum.xda-developers.com/showpost.php?p=58006383&postcount=1), due to the introduction of new sensor drivers! It should now works with other CM12.1 based ROMs, like crDroid and PAC, too. Please don't report bugs to qsnc, if you are using this kernel!
Features:
CPU: over/under-clock 1728MHz-192 MHz possible
governors: ondemand(plus), intelliactive, wheatley, ElementalX, ...
GPU: over/under-clock 487MHz-27MHz
governors: simple, performance, powersave, ondemand, conservative
File-systems: ext2/3/4, F2FS, exFAT, NTFS
Schedulers: noob, deadline, row, cfq, bfq, sio, fiops, zen, vr
intelli-plug hot-plugger and power saver (disable MPDecision first!)
Voltage Control (OC/UV)
Sound Control 3.x
poweramp controls (loudness enhancements)
screen colour tweaks
full NEON support
KSM support (Kernel Samepage Merging)
multicore power saver (recommended: enabled)
multirom compatibility
...
Performance: about 10% faster than original CM12.1-kernel with same settings, and some additional 20% speed by using maximum over-clocked frequencies (use at your own risk, every device is different!)
Configuration: Kernel Adiutor (https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor) or PerformanceControl 2.2.6 (http://forum.xda-developers.com/devdb/project/?id=600#downloads)
Install: just flash the attached zip with CyanogenMod Recovery, TWRP (http://forum.xda-developers.com/xpe...very-twrp-2-8-7-0-pollux-polluxwindy-t3187811) or CWM
Install a custom recovery first! The simple CyanogenMod Recovery, which comes with most ROMs, is pretty useless anyway..
Uninstall: re-flash the complete ROM (just re-flashing the original kernel is not enough!)

Version Information
Status: Stable
Just installed latest unofficial CM12.1 built by qsnc and this kernel. Seems great so far! Boots a lot faster and kritika plays faster!
I'm trying the overcloacking with Kernel Adiutor set to 1728MHz, I've to 3C widgets installed to monitor temperature and such. Great job!
May seem a bit offtopic but how is the combination intelliplug-ondemandplus?
I think i get some lag with this but it may be a placebo

First, I also used this combination, but experienced some lag, too. It is not necessary to enable intelliplug and I'm not sure if it does any good, since hot-plugging is handled by auto_hotplug. Actually it is not even included in the original EvoMix kernel.
I'm now using only intelliactive, which seems to keep the frequencies low most of the time, while producing only minimal lag.
But maybe it is really a matter of believe..

The over-clocking capabilities of the EvoMix kernel are rather conservative. I personally use it with maximum CPU and GPU frequencies and even a general -50mV under-voltage, and it seems to be perfectly stable. But no guarantee, every device is different!
Thanks for Kernel !
Multirom Patch inclusive ?

Traced the cause.After some time with intelliplug+ondemandplus cores 2,3,4 are permanently disabled.Now i am on intelliactive.Very good so far
I've been using Wheatley and OC 1728 for couple days now. No lag, no heat issues, everything is just peachy!
Hi! Can I use this kernel on my sgp321 Pollux? Tried to flash but get error.
Pollux build will be released later...

If you, or anybody else, is able to re-flash the original CM12.1 kernel via fastboot (in case something goes wrong) and is willing to beta-test, write me a PM!
Yes its kexec patched, but we need to make tab z official to multirom app support, problem is...im running out of time, full time job, 10 months old baby ...kernel is time consumer, thanks to BlackAfgan to maintaining it.
More goodies to come

So apparently my tablet hates me. I can't get this kernel to actually flash for ****. I'm using the 5/27 CM 12.1 from the OP. Tried both versions of the kernel. It acts as if it flashes but is much too fast and the kernel version is the same. TWRP 2.8.5.0 from the OP link too.
EDIT: Nevermind I guess. Moved it to the root of the internal and renamed it to a shorter filename and it pushed it properly. No idea what was going on.

I had the same problem, especially when I flashed an already flashed kernel. I never found the actual reason, but at one point it started to work perfectly all the time..
This is due the pretty complicated process of splitting the original kernel of and recreating the new one in real time, on the device. Normally the developer does this on his PC, and releases a directly flashable combination of the actual kernel and a custom ramdisk.
If other people have the same problem persistently, I may publish an conventional kernel. Please report!
Does this work on "[Rom][UB][5.1.x][SGP311]☆Dirty Unicorns v9.3☆ Unofficial +EvoMix Kernel" rom??
So i tested the latest version.I use intelliplug+intelliactive
No issues so far.Intelliplug is shutting down cores faster which will propably save some juice
Also feels a little colder than before when gaming(asphalt 8)
Hi falcon people!
This is my modified kernel with some kernel optimizations and some compiler optimizations.
The goal of abyss is to achieve improved performance/battery without the cost of stability.
I will not be overhauling this project with changes that are not logical to add.
This kernel should work on the latest 7.x.x (and maybe 6.x.x) roms like CyanogenMod and any other AOSP based rom.
How does one achieve this?
- build kernel with an optimized toolchain
- use compiler optimization flags (experimental)
- remove redundant code
- improve existing code with more efficient code
- reduce/increase speed of timers (depends on what type of function)
- etc. (most are not easy to explain)
Built with Linaro GCC 4.9 optimized for Cortex A7 with vfpv4 technology
Is there actually a performance improvement?
With all the changes added up, there should be. Whether or not one notices the difference is another thing.
Personally, I do feel the performance difference. It is easier to notice the difference with lower level specs like ours.
For those interested in how the kernel optimizations will benefit/work, please look at my github source and read the commit messages.
For those interested in how the compiler optimizations/hacks will benefit/work, please look at this article.

Asking for ETA's won't be necessary because I use this kernel as my daily driver.
I do not mind if there's some non-development/off-topic discussion here, just no discussion about other works that is nowhere near related to mine.
Also, please refrain from comparing works here; it really kills the spirit of development. Go do that in some other thread.

Frequently Asked Questions:
Is this a custom kernel?
I was asked this question once, and it posed as a real good question. I do not consider abyss to be a "custom kernel" per se, but more so as a modified kernel. The patches and features that go into this kernel do not make it customizable. What they do is improve what has already been implemented. It is like swapping a car's engine for a better one rather than just adding LED flooring lights and fancy car mats.
Can you add [this] and [that] feature to abyss?
Something I pride myself with this kernel is that it does not have a bunch of random, useless features or patches mashed into it. Everything put into this kernel is thought out well and tested. I see a lot of works being made popular because it has [this] and [that] feature when really, it's nothing revolutionary. As a matter of fact, most things added to any kernel will not make it 5x better than any other kernel. Most of the time, simple is better; and in this case it definitely is!
Main Patches and Features:
- intelliplug (default hotplug)
- intelliactive governor
- KCAL Control Driver
- kexec hardboot patch for Multirom
- USB Force Fast Charge patch
- Abyss Optimizations (compiler)
- disabled debugging for more performance throughout
- lots of patches for better performance here and there... too many to list
How to install:
Download kernel from Basketbuild
Boot into TWRP recovery

Sorry, I won't be adding underclocking to this kernel. There really isn't much of a need for underclocking a phone. In the long run, battery consumption will not be changed, maybe only at the slightest.
Also, the more frequencies added, the slower a CPU governor works. Most governors run calculations based on cpu load, checking whether or not it needs to move up or down a frequency step. By adding more steps, the cpu will throttle slower.
Just updated the kernel with frandom support. Also added some ramdisk modifications to support it.
More entropy == better performance.

Battery backup is good...give a try
It's great to see feedback from the users. New build with modified values; it should improve multitasking performance.

Yes, the battery is great, 18 hours standby and i get almost 4h sot, left with 52% right now. Anybody looking for great battery should go for it.
PixN KernelSo this is the only custom kernel currently available. It's got a custom hotplugging solution and built-in exfat support. The camera fixes are iffy at 2.99b, works in 2.99
This is best used with my custom rom, here, but will work with any AOSP N based rom.
Maybe it'll work on CM devices too but I'm not sure. You may lose recovery on flashing this. Don't panic, just flash Zach's TWRP recovery after the kernel.
Eventually this will see many optimizations.
Built with the regular 4.9 toolchain. (Uber from 3.2)
About the screen dimmer:
You can echo 0 to disable and echo 1 to enable it via the sys path /sys/module/mdss_fb/parameters/backlight_dimmer

Or just use ExKernel Manager.

Sure, but I think that also needs the rom to specifically add the module too..
(I'll add that to the linked rom)
@HaoZeke, I have been using your rom for almost 2 days now. It is much similar to the other AOSP Nougat. In both the cases, the battery drains fast. Does not even last half a day. The UI is not very smooth. The touch also needs some work on it.

Ok... Did you try the new kernel? The latest version (coming) has elementalx as the governor (enable by kernel auditor mod)..
My battery seems to do ok with the suggestions in the op...
Touch seems ok too.. Actually I build multiple times a day, it's possible an issue sneaked in.
The main reason for this rom is basically the native substratum support..
Does your substratum app show substratum or substratum legacy? In the uploaded release 1 for e6653 there was a small bug which was fixed for 1.1
EDIT:- I'm grateful for the feedback but this thread is for the kernel and related issues... Please post in the right thread...

Actually a full flashable version isn't currently a priority, since actually the system.img is a bit large to be zipped (cuz of the addition of gapps).
Eventually I'll start zipping the kernels, but again, not a priority..
It should be easy enough to set up.
First download the latest system.img from the ROM thread.
Then get the latest kernel here. (or whichever feature-set you want)
Also grab the recovery.
Put the phone in bootloader mode.
fastboot flash boot boot.img (or whatever the kernel is called)
fastboot flash recovery recovery.img
fastboot flash system system.img
Hey the latest build is up for anyone interested... This might be the last release for a while...
I feel like it's significantly improved... The camera needs work and some other bugs...
Battery life is around 1-1.5% idle.
Testers please post feedback.
@HaoZeke i flash the rom yesterday and the kernel. For me everything was working fine except the camera, whis is upside down. I like the rom, very smooth, i cant tel the battery cause i have 12 hs with it. The kernel you put for test for me is working fine. This kernel will work on CM?

Excellent, I'm glad the test kernel is working, could you try 2.99b1? That has many battery and performance fixes, the older kernels were giving me around 2-3% battery usage per hour, with the new one it's 1-1.5%..
CM I'm not sure, it should maybe work with cm-14.0 but cm-14.0 has been depreciated in favor of cm-14.1 ...
I don't know if there is a cm14.0 for the Z5..
By the way, if I may ask, why are you interested in CM ? Any particular feature?
I ported substratum on AOSP since the cyanogen theme engine wasn't ready for nougat...
So I was wondering if there was anything else people particularly wanted...

I will give a try tonight. I line cm cause allways works very good for me. Mm.. I like you dont need to flash supersu to get root. But with your rom and cm. There is no diference. Just cm is 7.1 and yours 7.0. I really like both, the only thing i dont like and more useful for me are camera and fingerprint, which both arent working. I will test the new kernel and will tell you in a few hours. Thanks!

Hello,
I started making kernel builds again.
CHECK BELOW FOR IMPORTANT INFORMATION!
YOU MUST USE MIUI Q FIRMWARE PACKAGE FOR THIS KERNEL TO WORK. OTHERWISE YOU'LL END UP IN FASTBOOT MODE FOREVER.
Camera won't work on a lot of ROMs due to imcompatible camera drivers in the kernel. This kernel uses a patch for MIUI Stable 11.0.4 release, which introduced updated camera blobs back in Android Pie. Double check, whether your ROM uses these blobs. MIUI Q uses different blobs too, thus won't work until Xiaomi releases it's kernel source code.
FLASH THIS BEFORE FLASHING MY KERNEL. I UPLOADED FIRMWARE PACKAGE FOR YOUR CONVENIECE!
DOWNLOAD LINK FOR MIUI Q FIRMWARE PACKAGE
Flashing procedure is standard - through recovery. Magisk is optional, only if you want root.

DISCLAIMER:
-There will be 1-3 kernel builds per week, unless there's nothing I can improve, then builds will be as is.
-Anyone, who has tested it already, give me some feedback in the comments.
-If you get freezes, crashes, restarts, write me up with a attached dmesg, log, anything, that can give me a clue what's wrong. Thanks. Happy JellyKernel'ing ^^

Is the any chance to get the turbo frequencies on the GPU?
I read that on some other page I can't remember where, can you please why that supposed frequency is not on the stock kernels, does it take to much energy?

I believe Qcom left off this frequency just because CPU is already close to some of their flagship SOCs in terms of CPU performance.
Everything in the source code is left done, you just need to modify a code a bit and you have higher frequency. If you want to go any higher, you would need to modify the code a lot more. Tried it and gave up on that.
It could be anything, really.
Moreover, you don't see too many phones using this exact SOC.
P.S. Funny thing though, this OC feels like placebo effect, like CPU is running faster but it's really not.
Think about it, when sdm660 came out, it was between SD821 and SD835 in terms of CPU performance. GPU is more or less the same as Adreno 430.
Gonna release new kernel build soon.
Still working out some quirks I come up every once in the while.
Stay tuned for news. Good day.

Overclocked? Using Evira for now on MIUI 11 Pie, but Evira is outdated..... Can't support Android 10
So, hope can have Overclocked kernel support Android 10

Yep, it's overclocked and it's for Android 10.
I've seen people running this with MIUI too.

Overclocked to ? 2.46GHz?

Yes, but I don't think I'll keep the OC for much longer. I really don't see the benefit of it.
Phone is already really fast and snappy.
I did a build with stock clocks and compared it to the OC one. And here's the surprise - there isn't almost any difference.
I fixed several known issues which bugged me a lot and those seem to remedy all of the problems I had.
Moreover, I hate overbloated kernels with features I don't use. I like being clean and compact.
Hi, the sound control (for speaker, earpiece and headphones) available or do you plan to add it in future? They get pretty handy really. I do appreciate keeping the kernel without much bloat though. : D
