[KERNEL] [CM PORT] [07 Oct] SkyHigh Kernel [R3_v1.4] [Synapse ++]
I only have so much free time, so I don't plan to update this kernel. I have other devices I tinker with and personally use.
I have given Devs who have publicly released their CM ROM's (as per GPL and XDA rules) and kernel sources on git, to use what I have done and adapt it to there needs.
This kernel is currently compatible and built for use with the CM ROM Port by @eousphoros. As I don't own or use a T700 WIFI device, I can't guarantee if this kernel will fix any issues or create more. Up to YOU to find out
I don't have time to build for any more devices I can't personally test & debug - sorry.
Let get it straight, I am not a real Developer, but I am UpInTheAir, former part time kernel “hack” of TW SM-T700/705/800/805, SM-N9005 LTE, SGT 7.7 JB & ICS Kernels. I now share with you my Exynos5 CM Port SM-T700 WIFI kernel compiled from official Samsung sources.
* I don't pretend to know everything, so if you can be constructive and help out this project, please do so. You will find allot of answers by searching gitHub, XDA and SEARCH Just like I do …......
>> SCREENSHOTS << from v0.5 : might not be always up-to-date !

Flash kernel
Boot and allow things to stabilize
Open Synapse & tap :
"understood" message about unstable boot
"select all globally"
"undo" button
"apply" ✔
Reboot and ensure "synapse boot completed" toast message
You should be good to go
BOOT-LOOP
Power off & let device cool
Wipe cache & dalvik-cache in recovery (if custom recovery)
Re-flash kernel
Re-boot
Let things stabilize and cool before touching anything
BETTER BATTERY LIFE
There are no best settings. User "HABIT" is #1 cause of battery drain, followed by screen, ROM & apps, modem etc
This kernel is built to be balanced with a good mix of battery whilst keeping performance
Decrease screen brightness
Use dark wallpapers and app themes
Check your wakelocks with better battery stats app & use Greenify app to stop unwanted apps self starting and running in the background
Suggest:
CPU governor = ondemand (tweaked for power efficient workqueues)
CPU 200-1900 MHz -25 mV
GPU 100-480 MHz -50 mV (100 MHz may induce some GUI sluggishness)
PowerSuspend Driver = Enable
Dynamic FSync = Enable
Dirty Page Writeback = Enable
CPU Multicore Power Saving = (2) Agressive
BETTER PERFORMANCE
Disable DVFS with [APP][Android 4.0+][DVFS Disabler]
Warmer device under heavy load, but within the safe CPU temp of 95 degC
HOW TO BACKUP YOUR STOCK KERNEL BEFORE FLASHING SkyHigh KERNEL
Boot into TWRP Recovery
Select Backup
Select "[X] Boot" only (boot.img/kernel)
Select Storage > Micro SD (if external sdcard installed) > OK
Swipe to backup
CAN I USE OTHER KERNEL CONTROL APPS
No, many features and options won't be available. Remove all other control apps to avoid conflicts !
Synapse is the recommended and has everything you need
HOW TO MONITOR LIVE CPU & GPU VALUES
CPU load & freq - available RAM - GPU freq - CPU temp - most resource intensive process
[APP][2.1+] Cool Tool
Download my personal cooltool_presets > unzip & copy folder to INTERNAL sdcard. If you have cool tool app already running, you must disable > overwrite existing folder > enable
LITTLE CORE CPU FREQUENCY
Real frequency is apparently double that reported by other apps
Example: min 200 MHz (real) in Synapse is reported as 100 MHz in SetCPU
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place (Thanks to XDA) - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
HIGH CPU/GPU OC >> excessive heat >> thermal throttling >> reduced clock frequency >> DECREASE PERFORMANCE
DO NOT KILL PROCESSES
This feature allows the user to define processes and system processes white-lists filled with the preferred process names and to not be killed by lowmemorykiller, unless it is absolutely necessary.
When a the lowmemorykiller needs to free ram, it will first kill the processes not included inside the two process name lists chosen by the user.
If there are no more standard killable processes, then it will be necessary to kill one of the processes included inside one of the two white-lists, to prevent system hangs, slowdowns, etc.
You can find the [SkyHigh/Synapse] folder on your internal sdcard and add one process name per line. Lists updated on reboot.
Max 25 processes
Example only:
Code:
com.ea.games_r3_row
com.quoord.tapatalkxda.pre.activity
DYNAMIC MANAGEMENT OF DIRTY PAGE WRITEBACKS
* [Christopher83]
This feature allows to have two different intervals for dirty page
writebacks and to dynamically manage them when the system has been
resumed (it's active) or when has been suspended.
Three new procfs parameters are exposed inside /proc/sys/vm path:
- dynamic_dirty_writeback is the activation status of this feature,
set 1 to enable it, set 0 to disable it and use the standard behaviour
- dirty_writeback_active_centisecs is the interval for the dirty page
writebacks when the system is active (screen on)
- dirty_writeback_suspend_centisecs is the interval for the dirty page
writebacks when the system is suspended (screen off)
This feature is in part inspired on Francisco Franco's patch:
https://github.com/franciscofranco/mako/commit/34d79548cf16b69c7d0154836018e7f258a22947

BACKUP & RESTORE
If the backup isn't visible, reboot device and ensure for have "synapse boot completed" message. Otherwise synapse won't read the file.
Reboot after applying your new settings

SEGMENTATION FAULT
I don't believe it's kernel related, but rather busybox
Try uninstall your ROM busybox with this app. https://play.google.com/store/apps/details?id=stericson.busybox and reboot.
Re-flash kernel
Use the busybox that comes with the kernel located in /sbin
Also try to update your SuperSu and su binary if it asks and reboot.
USB KEYBOARD / MOUSE
Base project: https://github.com/pelya/android-keyboard-gadget
Required app: USB KEYBOARD
For best results, enable & use Hacker's Keyboard
Steps:
Ensure device USB debugging
Connect device to system via USB cable
Enable in Synapse > USB > USB Keyboard / Mouse >> Enable & apply
Start USB KEYBOARD app

Thanks for the hard work, @UpInTheAir! In coming from the debloated stock rom and your other SkyHigh Kernel should I wipe everything, flash this Kernel and then the CM ROM? Or should I flash the stock kernel, CM Rom, set it up, then flash this kernel?
v1.0 released
R3_v1.0 kernel is now released for T700 WIFI CM Port ROM for supported 8.4" models
Change-log is in Post #2.
Ensure you flash the kernel for your device model !!

Please read Post #2 REQUIREMENTS section again. First User post is ROM related...........
I have nothing to do with the ROM, and User should read the ROM thread for instructions on how to flash that.
Personally I would.
1. Make Titanium backup saved to external sdcard
2. Make full TWRP backup and saved to external sdcard
3. Format: system, data, cache, internal storage (just to make sure)
4. Flash CM ROM Port
5. Boot device
6. Reboot & flash SkyHigh CM Port kernel

Thanks! Was just rereading your thread and saw that thanks mucho! I'll be giving this a run and looking forward to synapse con CM!
Flip cover
FLIP COVER now working for supported covers !! :highfive: Will be in next release
Tested with official Samsung Flip cover:
Open = screen ON
Close = screen OFF
Before you ask: NO, I don't know how to make this support non-official Flip Covers Patches and work-arounds on other devices don't work
Nice, looking forward to regaining that function on the book cover.

The case functionality worked beautifully. Thanks!
On 2 occasions when quickly opening and closing the case, the power menu came up.
No biggie, went away after closing the case. Even the speed that the screen came on is noticeable faster than on stock rom.

That happened to me once, thought I may have bumped a button..... Obviously not. Edit: can't re-confirm anything, because I'm back to TW
The stock ROM is a lot heavier and more indepth features to resume. There is actually code that can be tweaked for delay in open/close, but I'm not going to fiddle with it. It seems about right. Also the PowerSuspend driver can affect the resume delay too. There are notes in the github commits by Yank.

I don't own a T700 or use CM. I only flashed to my T705 to ensure it booted and kernel functions work.
Who knows about battery. ... The kernel has options exposed for users to tweak how they wish. I can't do any more than this.
Ill try and update this kernel in the next day or so. Just had enough for the moment
I own a T705.
I followed the procedure and although the system booted and the kernel seems to be flashed correctly (at least from what I can see from the info tab under settings), it seems that I lost root. Synapse doesn't work (as it says I have no root).
Now I'm trying to root again and see what happens..
EDIT: Rooting was unsuccessful

Not a kernel problem.....
Read the ROM thread. You need to re-root
My procedure I did was prior to a most recent ROM release where root had been removed.
This is a port of Optimus Kernel by Flashhhh for Peregrine
Must sure to thank him - Here
Not compatible with Dirty Unicorns atm as it's using the older cm-12.0 kernel source meaning wifi will not work if this is flashed.
I present to you my own kernel which has been built with many optimizations and tweaks. This kernel will work on lollipop roms(Not for stock roms) only.The main aim is to provide a stable kernel with optimizations.
I hope you all will like it
Enjoy!
Note: R12 or later will work perfectly only on LP bootloader. You need to be on a rom which has implemented new kernel sources. Read post #3 about bricked hotplug.

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.
Pls Read This before flashing:
You need ROM's default kernel before flashing this as this kernel makes use of AnyKernel 2 by @osm0sis. Make sure you have it otherwise clean flash the kernel with the rom to avoid any issues.(At least dirty flash rom+kernel) Credits to @attack11 for some part of install script.Read FAQ's and changelogs in 2nd post. THIS KERNEL COMES FINE TUNED OUT OF THE BOX.
DOWNLOADS:
AndroidFileHost
How to Flash:
1. Download the kernel and place it into your phone storage
2. Reboot into recovery
3. Reinstall(Dirty flash) Rom + the kernel
4. Reboot and enjoy!

F.A.Q. - Read this before complaining!
1. My phone exploded, HELP!
A: I don't answer to problems without a log. The log file is in /proc/last_kmsg. Paste it on pastie.org and link it on your post. Logcats are useless for Kernel purposes, don't bother posting them.
2. This kernel works on Y or X rom?
A: Works on CM12/12.1 and AOSP roms that have the latest wifi drivers. Not for stock roms!!
3. OMG BATTERY SUCKZ, ITZ DEAD IN 45 MINUTES, HELP!
A: As you can imagine I don't build kernels to decrease battery life. All the battery life problems come from your apps, either Facebook, or Maps, or some Location Service being enabled etc etc. Check your damn wakelocks and fix them, the kernel is not responsible for them.
4. How do I flash this?
A: Read the OP, theres a reason why I added instructions on it.
5. What is a data loss? Did I just had one?
A: Data loss is simply having the connection cut for X periods of time, usually few seconds. Grey bars means the device is not connected to Google services for some weird reason, but you'll still have internet connection.
6. OP is arrogant, I'm gonna call the Internet Police?
A: Deal with it.
7. D2TW not working? It may be a hardware issue

What is msm_mpdecision?
100% kernel based multi core decision! (should cpu1/2/3 be online or not?)
This is a special version modded by neobuddy Plus the idle frequency and some load thresholds have been adjusted by me.
Some Configuration:
startdelay = time until mpdecision starts doing it's magic (20000)
delay = time between checks (130)
pause = if something else plugs in the cpu, fall asleep for 10000ms (10 secs)
scroff_single_core = if the screen is off, don't plug in cpu1/2/3. Additionally: Unplug all cpus except cpu0 when screen is turned off (1)
enabled = enable(1) or disable(0) mpdecision. This does not affect scroff_single_core!
min_cpus = min cpus to be online, cannot be < 1. Default: 1
max_cpus = max cpus to be online, cannot be > 4. (if you set it to 2 and min_cpus to 1 you will basically have a dualcore) Default: 4
idle_freq = a value against that will be checked if a core +/- is requested. (600 MHz)
mpdecision's input event boost, aka project butter
This will boost your min cpu speed if you touch the screen or press a button and gives you full control.
In those events the min cpu freq will be risen to a predefined value on every online cpu. This boosts overall reaction times and smoothness a lot. (works similar to the qcom mpdecision binary)
Thanks for bringing another kernel to our device, Kayant! Much respect!
On a side note, is Pink Kernel no longer being updated on the original developer's side, or have you abandoned it??
Thanks as always!
Thank you for your work, I will give it a try immediately!

More developer side but from looking at github pinkflozd might be coming back soon maybe?
@Kayant good work dude!
So the reason my dt2w doesn't work is because I changed my screen? Thank you for clarifying that for me. I had a feeling that was my issue but I wasn't certain.
Sent from my Moto G 4G LTE (XT1045) Retail US variant
ROM: SaberMod 10 (5.1.1) 4/30 build
Carrier: Cricket Wireless
is it good for daily use?
Some of the option you have listed in the OP seem not to be present, I am referring to CPU underclocking (min freq. 300 MHz here) and GPU under/overclocking (min 200, max. 450)
My xt1039 does not boot... It shows the motorola logo, then il vibrates and the screen becames black.
I'm using the beeto's CM 12.1 and I can't find the log file..
Got another issue, too. IntelliPlug (max frequency with screen off: 300 MHz), Interactive governor. When I woke up the phone and started scrolling around, I found it a bit laggy; I checked in Kernel Adiutor, max and min frequencies were both set to 787 MHz, even though I personally set them to 300 MHz/1194 MHz before. Reverted back to Spirit Kernel for now!

Kayant I faced that issue as well. Apparently I tried to flash it on AICP, Beeto's Unofficial CM 12.1... It showed the bootlogo and then it would stay blank till I restart it or something. And I did reflash the ROM's cleanly before flashing this kernel
However it works fine on Official CM12.1 and BlissPOP.
Am I missing something?? Can @Flashhhh help some fellow Peregriners????

Yes I was! Will try with another ROM, I'll flash AICP
Thank you anyway!
(If you have some time, take a look to slimrom thread, thanks )
Just flashed on official CM 12.1.
So far the frequencies seems to be workning as they should, will report back if anything weird happens. Using the kernels stock settings.

Hi guys,
I want to present my kernel for the Samsung Galaxy S3, that allows you to overclock up to 2 GHz. This kernel is based on the official Boeffla kernel for CM14. Although the official Boeffla kernel supports CM14.0 and CM14.1, my kernel supports CM14.1 only, because CM14.0 for the SGS3 isn't supported by the CM team anymore. It may run on CM14.0 as well, but please don't report any errors if you use it with CM14.0 or any other OS than CM14.1.
Feature list:
- Every feature from official Boeffla-Kernel (6.1 final)
- Support for Synapse (partial) and Boeffla Config (fully)
- CPU overclocking up to 2 GHz
- CPU: 100MHz step added to save power
- Faster boot process due to some internal improvements
- 3 new governors added (adaptive, conservative, interactive)
- CPU voltage can be chosen between 600mV and 1600mV
- full F2FS support (backported from Linux 3.19)
- Charging current can be set up to 2.1 Amps
- Battery percentage never reaches 0%, so the phone won't turn off at low battery
- No overcharge anymore due to an internal improvement
- Early suspend adjustable up to 5000ms
- more undervolting profiles for the GPU
- much lower brightness can be set than on stock kernel; the display will be almost black on lowest brightness level (maximum possible brightness stays the same)
- Configurable kernel logger (turning kernel logger off is not stable on CM and LOS)
- compiled using GCC 7.2.1 by Linaro (Thanks to ZaneZam for publishing the kernel-specific GCC-6-code; this works with GCC 7 as well!)
For configuration I recommend Boeffla Config.
You can use your old config you had using the official Boeffla-Kernel, but this may lead to minor problems. So I'd recommend to reset Boeffla Config before you flash my kernel. If you already use my kernel and just upgrading it you can use the old config without any problems.
WARNING!!! Nobody except you can and will be responsible for a damaged or bricked phone due to my kernel. It's very unlikely that my kernel harms your phone, but it's not impossible.
Have fun using my kernel and feel free to ask questions about it!

Recommended settings from the developer
I'd recommend the following settings to be applied to my kernel:
Battery saving:
Doze enabled
SELinux strict
Governor: conservative or intelliactive
Scheduler: deadline
File system tweaks: both on
CPU maximum freq: 1300MHz
CPU minimum freq: 100MHz
CPU idle mode: AFTR+LPA
CPU voltage: set it as low as it is stable on your phone
GPU frequency profile: 108/160/200/266/350
GPU voltage: set it as low as it is stable on your phone; typically you can undervolt more than 100mV here
Boeffla sound: configure it by yourself until you get the best sound out of it
LED brightness: 40 or less
Touch boost: disabled or 600MHz
Touch wake: disabled
Early suspend: 10ms (default on my CM14.1 kernel)
MDNIE settings: configure it by yourself until you get the best out of it
Touch key LED: same as MDNIE settings
AC charge current: 2000mA
USB charge current: 500mA
Wireless charge current: 1000mA
Swappiness: no overwrite
Low memory killer: default values
System tweaks: off
zRam: off
TCP congestion: default
Entropy settings: default
Android logger: off; except for debugging
Kernel logger: on
Performance:
Doze enabled
SELinux strict
Governor: intelliactive or ondemand
Scheduler: deadline
File system tweaks: both on
CPU maximum freq: set this as high as it is stable on your phone
CPU minimum freq: 100MHz
CPU idle mode: Idle only

GPU frequency profile: choose either a profile or overclock manually; you can set this as high as it is stable on your phone
GPU voltage: set it as low as it is stable on your phone
Boeffla sound: configure it by yourself until you get the best sound out of it
LED brightness: 0 to 255; choose it as you like it
Touch boost: 1300MHz or 800MHz
Touch wake: can be enabled if you want this feature
Early suspend: 10ms (default on my CM14.1 kernel)

TCP congestion: default
Entropy settings: default
Android logger: off; except for debugging
Kernel logger: on
For a combination of performance and battery saving you can either combine these two profiles or leave the default settings of my kernel. If you don't know what a specific setting does I'd recommend you to leave the default value that came with my kernel.
Could You make the CM11 Version please
It's already finished, but you have to compile it by yourself because I never published any zips of the CM11 version: https://github.com/Oebbler/elite-boeffla-kernel-cm11.0-i9300
The instructions on how to compile it can be found below the source tree (on top of the readme file).
If you have troubles compiling it please write to me.
@Oebbler1 Thank You so much for your efforts I am going to try it Thanks for keeping updated our S-3 :good:
Is it safe to overclock that much? And can you post best configuration for this kernel, in your opinion?
Thanks
Pls compile it-cm11.thanks in advance
It is the wonderful kernel. It is really safe because when I too overclocked my phone and it was unstable so I used the normal boeffla kernel and after used the elite kernel again. The kernel cooperate with crdroid v1.5 on my phone. I am really delighted that this phone has 100 mhz frequency cpu and 1500 mhz frequency cpu and more powerful charging. This phone by persons like you is brilliant even today. Thanks for your hard-working.
I think 2 ghz is too high lol my device is direcly crashing
But the 100 mhz underclock rocks:good:

It is safe as long as you don't overvolt above 1500mV. I'll post my recommendation about the config tomorrow.
Can i flash it on top of boeffla kernel?

Yes, but I'll publish new versions in the future. Every published build of my kernel can be downloaded in the "Download" section of this thread. There's an icon below the title of the whole thread that says "Download". If you click there you can download every build of my kernel.
I installed it but I have a lot of restarts with aicp 12.1, thank you good job !!
You experience these reboots because my CM12.1-kernel includes the ramdisk for CM12.1 only and doesn't support the anykernel method Boeffla and I are using since CM13.0. I'd recommend you to upgrade as soon as possible to an Android 6.0-based ROM because most Android 5.x-based ROMs don't work well on the Galaxy S3.
Thank you for your feedback!

OnePlus 6 / Oneplus 6T
Youtube review of Kernel and Avengers theme by @hypergamer1231
Concept
Flash and be happy out of the box!
The kernel provides 4 Spectrum profiles and 3 Franco Kernel Manager profiles (Pie only) for most usecases. Balanced (default) / Battery / Performance / Gaming. For choosing another profile as Balanced please install Spectrum from the Google PlayStore.
If you want to modify the profiles just run a kernelmanager like EX Kernelmanager and change what you want.
First completely unified kernel for the OnePlus 6/6T OOS and Custom ROMs
One unified zImage!!!
To preconfigure the kernel uses a config file made by well known Senior member @xXx
These are the tunables you could modify:
Defaults in [ ]
Profiles battery, balanced, [performance], gaming
SELinux [permissive] / enforced
CPU minimum frequency [300], 403, 480, 576
GPU minimum frequency 180, [257], 342
GPU Input boost off 257 [342]
GPU maximum frequency up to 842 MHz (comes with 710 stock frequenccy set!)
Flickerfree display mod by @Devries (ImageBreaker kernel OP6T), default is off
Governor setting [pixel_smurfutil] or smurfutil_flex
The SmurfKernel configuration file is placed in /sdcard/SmurfKernel: If you want to use the kernel with it's default configuration just flash it!!! For custom changes please edit the SmurfKernelConfigurationEditor by @tanish2k09. The settings are applied saving the config. Your actual configuration is written to smurf.kernel.bootlog.
It's recommended to use my kernel paired with

smurfutil_flex
Pixel_smurfutil is a mix between Pixel 3 schedutil, helix_schedutil and electrotuil. Next frequency selection is load based and in suspend all cores are forced to a lower frequency max level. Three big cores are forced to operate at minimum frequency (825 MHz). One big core could clock up to general maximum, 1300 MHz). In normal operation load based frequency selection is used.

Thank you! :good:
What's the difference between the usual schedutil and helix_schedutil?

The difference between all 4 governors is the way how next frequency is selected. Electroutil and pwrutilx are ramping flatter if the device is suspended. Electroutil is cutting max frequency if device is suspended. Check governor settings, you could adjust it. Helix is ramping frequencies different based on load scenario. Lower load, flatter ramp. More battery friendly in my opinion.
For future versions i'll mix a new governor that combines these concepts.

I am really impressed by the kernel, my phone is flying right now! Thank you!
Tested on the dp2? Thanks

You can use Kernel Adiutor or EX Kernel Manager

Ok, I really need good battery life so I'll go ahead and choose Helix. Thanks
@ pappschlumpf
Welcome & thank you.
@pappschlumpf: Thank you for your kernel! I am trying it since about 12 hours. But I have two questions:
1. How can I adjust the "vibration control"? I can't find anything related to "vibration" in Kernel Adiutor
2. I found a setting in Kernel Adiutor under "Misc" which is named "Software CRC control". What does this setting? I can't get the feature behind the setting from the description itself in Kernel Adiutor. Is it a new feature or something that is only deactivated in your kernel?

With Adiutor you dan't have all options. EX Kernel Manager recommended. The plan is to include Synapse support, like i have in in my Note 8 kernel. But that needs some time. There're many options in the OP6 kernel that the Note 8 kernel isn't supporting.
CRC Control disables the crc check for internal memory access. Faster, but well memory errors wouldn't be detected.
It's not a new feature, most kernels for the OP6 support it.

Thank you for your fast answer. So I will have a look at the Ex kernel manager.
The CRC control is a feature which I didn't see in the other kernels I tried. Maybe they are there but not controllable. That's something I can't see.
To make it clear for me: I see the CRC control as disabled (this is the untouched status directly after flashing the kernel). Is this correct or should be the CRC control activated by default?

Yes, faster option, disabled is default. If your memory is working as expected crc is not needed. On an old device with defect mem you may need it
"A kernel is the central part of an operating system. It manages the operations of the computer and the hardware - most notably memory and CPU."
It should be installed via Recovery (TWRP) over any LOS/AOSP 14/15/16/17-Based ROM. It doesn't need any tweaking with any app, just install it and use it.
BUT you can use Boeffla Config app (available here on the next post) or Kernel Adiutor if you like tweaking.
This kernel uses codes from other kernels, as you'd expect in an open-source community, most notably code from Boeffla, SmartPack, Lolz, Ares and Intelli-kernel
It has UNIQUE features like:
- a different "low memory killer" algorithm wrote by me. Extremely simple, but multiple apps can be killed in a batch!
- zcache is disabled for really *freeing* up memory that was used for caching files
- a different default cpu hotplugger. ALL kernels (even LOS/stock) relies on Qualcomm's vanilla MPDecision, I wrote my own
- Tuned CPU governor (it's the default). It's basically the Interactive governor but with a LOT of tuning to match up with the tuned hotplugger. Did you know stock/los roms uses a multi-socket Interactive governor that doesn't match our phone's cpu?
- many many many MANY compiler optimizations not found on boeffla kernel, LOS or anywhere else!
- MANY unused code simply REMOVED to free memory and CPU. People ADD a lot of stuff on a kernel, I like to remove
- compiled with 2019 GCC version 9.1 (instead of the ancient version 4.9 that EVERY ROM uses)
- Your battery will be charged to "real" 100% like TWRP does
- many unstable cpu and gpu governors and i/o schedulers removed. they only wasted space
- ext4 tweaks
- fair scheduler tweaks
- removed 3 touch boosters code.. why so many? just to raise your clock on every single touch?
- Maple i/o scheduler
- lowered "read ahead" of files and inodes.. why would you read something you don't know you'll need?
- lowered maximum i/o requests for lowering ram usage while writing to SD (internal or external)
- removed a lot of DEBUG code.. why release a software with debugging code built-in?
- removed network protocols we would never use
- removed some compatibility code
- removed dynamic fsync, why would anyone want to enable fsync in any moment anyway? it has been disabled by default linux kernel for decades!!
- decreased commit DELAY of file changes from 20s to 5s, which is linux default. there's no advantage in keeping new/modified data on ram for too long
And common features:
- Max cpu voltage set to 1.4v
- Min cpu clock set to 268mhz instead of 300
- Max cpu clock set to 2995mhz instead of 2457
- Max gpu clock set to 657mhz
- Compiled to speed, not size
- Voltage table for undervolting or overvolting
- Charging level for AC, USB and Wireless charger can be set
- LED fading control + brightness
- zen, noop bfq and sioplus i/o governors
Overall your phone will be snappier, and less battery hungry
You can go back to your rom's default kernel by simply installing rom's .zip again. No need to wipe anything ever!

thank you for great work
Thank you very much.
why a new thread?! and also the download link is missing.^^
Where's the download link, appears to be missing.
xda is completely ****ed up
Thanks a lot for your work! But where do I get this kernel?
I've just upload a new version for klte only for now. TEST with los15.1 and 16 please.. and see if boeffla config app is still working with it..
and please don't flood this thread about the variants
