Want to unleash the full potential of OnePlus 2?
Get NoGravity Kernel!
Why is it called AntiGravity kernel?
Introduction
Familliar with NoGravity Kernel? This is a lite version of the it... AntiGravity doesn't have overclock and custom thermals. AGK was made for ROM developers who wanted to integrate NGK into their ROMs without the heavy modifications that NGK requires. This Kernel is for Performance but it still gets descent battery life due to some added features (see below).
No Gravity App
To tweak the kernel easily, here's my No Gravity app! featuring custom profiles (Battery, Balanced, Performance, Gaming and Gaming+). My kernel offers some features that cant be found in other kernel tweaking apps. You can find them lower in the thread.)

Initial boot might heat up device a bit, which is normal - Let it settle
I'll recommend before coming to conclusion, give it at least 2 complete charge cycles and then raise any issue.
To install
Flash AntiGravity_Kernel-vX.X.zip file in TWRP (Latest TWRP Recovery Recommanded)
(Optional) - Clear cache and Dalvik

Two downloads from two different US mirrors reported as corrupt by TWRP... possible to reupload?
Well I finally got it to load by doing ADB sideload, but when I install the no gravity app, I can't get past the splash screen. It asks for root, I grant it, and it freezes.
Any ideas?
Wonderful kernel - the *only one* that many HAVOC rom's pie camera to work using built-in camera app & 3rd party. ( I tried no-gravity eas but it has that camera/video recording issues ).
is there anyway to add support for fast/quick change for this fork of kernel ( aka "anti gravity" ) ?
thanks !

It supports fast charging, but won't be as fast as NoGravity Kernel since it doesn't have a custom thermal configuration
Kernel + App Update
Good news! New build (2.7) and new NoGravity 2.7 app are up , please read changelogs in post #2! thread updated..
Don't forget to take a look at the new Battery Charging Screen! Yea offline charging issue is fixed
Two days in a row I left phone with 20% battery and went to sleep, when i woke up it was turned off. Looks like idle drain on latest version. I have clean flashed crdroid. Will look into battery stats and monitoring, if its some apps caus but i dont think so.
Kernel + App Update
Good news New NGK, AGK & NGK EAS Builds along with the App updates are here! Please do read the juicy changelog! Thread updated quite a lot and new detailed infos about the EAS Kernel in NGK's thread post#3. What suit you best picture with charts to compare the three kernels updated in OP too.
For Android 10 users, make sure you flash latest Magisk after you flash the kernel!
If you don't want root simply do not install the app afterwards
Let's celebrate this new release with a new antutu benchmark record and a new Logo! => (spoiler alert)
As you can see from the new logo, NGK and App will support Xiaomi Pocophone F1 device shortly..
As I put a lot of time and effort into Android development, wmbruckner (OnePlus 2 user now on Pocophone) created a crowdfunding so I can get the device for NGK development,
If you want to support me you can do so here:

/* 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.
/* 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. Hard. A lot.

Initial release
/* Customizing kernel */
You can install Synapse from the Play store to control voltage and other frequencies.
To control some core kernel parameters, create /sdcard/arter97 as a directory and do the followings
--- Enable Adaptive LMK ---
Enabling Adaptive LMK will increase responsiveness at the cost of reduced multitasking capabilities and battery life.
Create a text file with 1 letter "0" under /sdcard/arter97 named "adaptive_lmk" and reboot
--- Disable LED fade ---
If you have issues with other 3rd-party LED controlling apps, try disabling it.
Create a text file with 1 letter "0" under /sdcard/arter97 named "fade_led" and reboot
/* To kang or not to kang */
I prefer "open" to all stuffs, explicitly except for my personal kernels.
I've once used to use private Git repository for my kernels and just release the source-codes as a tarball,
which means that other developers who are interested in my kernel's changes would not get the specific changes they want while not violating XDA forum rules or GPL.
That was almost 3 years ago which by then, I was a newbie developer on XDA.
I was afraid other big developers merging all of my changes and I'll get buried down.
However, I've changed my mind and opened up my Git access to everyone after thinking my previous actions did not belongs to XDA's spirit.
That was a big move for myself of re-thinking what should be open.
Later down on the road as I gained more development skills, I've contributed into CyanogenMod and other's custom kernel and ROMs for fixing stuffs, introducing new concepts or improving performance.
During such process, there were quite a lot of occurrences where I was actually the first one to do those things.
For those who're familiar with "temasek ROM", you may know that after I became a contributor, temasek rose even more into the center of other AOSP ROMs' attention, as I was the first to introduce new exciting stuffs such as compiler changes or f2fs. And I quickly gained dozens of followers on my GitHub account.
And eventually, people *kang*ed my changes. Sometimes invalidating my authorship.
It surely is not a right thing to do, but I let it slide as it didn't matter that much. I believed that if my changes are good enough, it'd be better to end up with a larger user base rather than being a **** trying to hunt down every ROM developers who're doing it wrong.
Same story goes to my ROMs.
My real first popular ROM was back-to-n00t, which is a ported ROM from Galaxy S3 LTE to provide stable Touchwiz KitKat experience to the Galaxy S3 3G users.
I opened up everything to GitHub. And I even encouraged that other ROM developers to use my ROM as a base to work on their own ROM as I knew there are a lot of Touchwiz ROM cookers who're way better than me on modifying SystemUI or frameworks(via smali) BUT aren't too good on porting ROMs. I hoped that my ports can be a great base for others to work on their own modifications.
Now those spirits repeated on the Galaxy S6, I opened up everything about back-to-n0t3.
However, I do not do or believe those same things with the kernels.
There are far less kernel developers on XDA compared to ROM developers. ROMs are much more appealing for an "Android newbie" to go tweak. You can modify UI, enable some hidden settings and even port features from another devices.
So when ROMs gets copied off, users can easily distinguish if that was stolen or not.
Let’s say a well-known developer A ported S6 designs and features to the S4. Next day, less-known developer B uploads a ROM on XDA that claims to do the same thing. First thing that comes to the users’ mind would be ‘Is that guy a thief?’.
However, same thing cannot be said on the kernels as they work on a much lower level. You can’t distinguish individual custom kernels just by staring at your phone.
If a ROM developer choose to go use other’s custom kernel and integrate it into their ROM, it’s most likely that users won’t appreciate that custom kernel developer whose work powers that ROM. Let’s face it, not all users care about “Thanks to”, “Credits” sections, and let me tell you, those are the majority. Now some custom kernel developers might be OK with that. However, I’m not. Unlike most developers on XDA, I got fascinated to Android because it runs on Linux kernel. Modifying Linux kernel was the first thing I’ve done on my Android device, not modifying ROM. And I spent years and years on gaining information on Linux/Android kernels and tweaking, coding myself. While I don’t necessarily care users choosing to NOT use my kernel, I cannot stand that my kernel would be installed on one’s device which its owner don’t even know which kernel, which developer who made that kernel is. That is why I’m against with the idea of integrating custom kernels into custom ROMs. If you want your users to have a custom kernel, let them learn themselves what that kernel really is, what does it offers, and who developed it. “For the ease of flashing/installation” is not an excuse for me. Take yourself a few more minutes to download a kernel from the web, and a few more seconds to flash a secondary ZIP file from the recovery. Is that hard? Time-consuming? Absolutely not.
I hope everyone gets the idea why I'm sticking with the idea of "don't integrate my kernel into others".
Cheers.

duki994 Kernel for Stock TouchWiz MM ROMs
Development stopped. I don't have device anymore
This is for MM only!!! For LP go to duki994 LP kernel thread
LP kernel thread
It's based on official Samsung CPE6 sources for Marshmallow firmware.
Important note:
This kernel should work on any custom ROM that is stock lollipop based and is based on stock CPE6 source
Features:
* Wolfson Audio control adapted to G900H implementation (thanks to @AndreiLux)
* Charge control by me (@duki994)
* CPU voltage control for both A7 and A15 cluster (thanks to @AndreiLux)
* Exposed all OPP voltage controls (thanks to @AndreiLux)
* LED fading control (thanks to @AndreiLux)
* Powersuspend v1.7 by @faux123 and @Yank555
* MM and FS powersuspend mods ported from @dorimanx's LG G2 kernel
* SCHED code fixes
* SCHED: HMP thresholds changed and new patches implemented
* OF code updated --> better/faster reading of DTS and faster operation
* Many changes related to ARM instruction code and lowlevel ARM core management
* Enabled NEON mode in kernel with full VFPV4 support
* Added new SHA256 , SHA512, SHA1, ASH2 and AES NEON accelerated algortihms - now blazing fast
* WiFi fixes
* NET updates
* LMK updated and added new feature: Adaptive LMK --> better multitasking
* Enabled all TCP congestion protocols and set Westwood as default (best wireless performance)
* Wakelock disabler: You can disable some common Samsung wakelocks in Synapse "Misc" tab if some of them are draining your battery
* Fully configurable in Synapse application (download from Google Play)
For kernel configuration use Synapse
Download from Google Play.
Google Play link for lazy people:
https://play.google.com/store/apps/details?id=com.af.synapse
/* Important note to other devs */
You cannot include this kernel in your ROMs. I can't be responsible if anything goes wrong, I can't help with any issues without knowing kernel version and users should be routed to this thread if they want this kernel, or if you recommend it. I think that it's best to separately view custom ROM and custom Kernel, so each dev (ROM or Kernel one) can work on bugs/features and make it as compatible as it can.
However, you can add this thread link and mention me in your thread, as so people would know where to ask if kernel problem arises. I will do the same for you
Warranty void
By flashing this kernel you will void your warranty. I'm not responsible if you brick your device, or if someone starts nuclear war.
Note:
Don't change voltages on "Busses" tab if you don't know what you are doing. It can reboot your phone if your memory controllers, ISP or MMC controllers that can't handle low voltage.
If someone happens to have bug with WiFi saved password being lost every reboot, here is fix:
WiFi pasword resetting fix:
Code:
1. open your build.prop file
2. find line ro.securestorage.support
3. change it from true to false (if not already false)
This line being on true WILL make your WiFi forget password each reboot. This is due to Samsung's rooting restriction and other Samsung specific workarounds to stop rooting and flashing. Any custom ROM probably has this line changed to false.

SuperSU problem fix:
After each kernel installation you'll need to reinstall SuperSU from Play Store or from apk.
I'm trying to solve this problem currently.
Root and busybox work as intended. Problem is only with SuperSU app.

CPU OC is unnecessary for our device.
And CPU underclock won't save more battery.
It'll actually drain more battery.
On very low freqs CPU can't finish task and needs to bump freq up. The freq changing is much more power costly than being on stock 500mhz min for A7 and 800mhz min for A15.
Look at power curves.
We have power curves similar to those on 5433, just about 20% lower I think
This are high performance cores (A15, A57, A72...)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And this are for power-saving cores (A7, A53...)
The shape of curve for our chip is almost same, only with lower consumption. Look how exponentially it increases as you put frequency after 1.2GHz.
So if I enable OC to, let's say, 2GHz, then power consumption would be 20% higher than on 1.9GHz and performance would be 4% higher.
But don't let that fool you. Phone may last 2s-3s on 2GHz. Then it would throttle down when it overheats due too much power dissipation.
So in the end you get much lower performance than you would have on 1.9GHz.
And keep in mind that Exynos 7420 is built on 14nm FinFET technology, and Exynos 5422 is 28nm HKMG.
So we may use a bit more power than 7420.
My observation:
I get maximum performance on 1.8GHz. Phone is heating at least 10 celsius degrees less than on 1.9GHz so almost no thermal throttling.
For games and high performance apps, I suggest that you lock A15 core cluster on 1.8GHz.

Tips & Tricks
I suggest you use Xposed for Samsung MM ROMs and Xposed module called XTouchWiz.
They are both maintained by @wanam
XTouchWiz Recommended settings:
* Disable TouchWiz DVFS (you'll get enormous performance boost)
* Disable KNOX/TIMA (disabled TIMA in kernel, but XTouchWiz uses Xposed method hooks to disable it in ROM)

Not on boot. You can set it to permissive in Synapse.
But I use patched sepolicy from SuperSU (thanks to Chainfire), so permissive/enforcing shouldn't make too much difference (or problems) anyway

For me, alpha versions were awesome. This one should be better.
Especially when on WiFi/Data or any other internet connection.
If you have bigger battery drain, then you have something wrong in you ROM setup/boot scripts.
Plus wait for a few days to get accurate battery life. I released this version today so no objective batt life readings yet
Be patient and ot'll pay off

For me, alpha versions were awesome. This one should be better.
Especially when on WiFi/Data or any other internet connection.
If you have bigger battery drain, then you have something wrong in you ROM setup/boot scripts.
Plus wait for a few days to get accurate battery life. I released this version today so no objective batt life readings yet
Be patient and ot'll pay off

I am tested ut and not that much i will use it for 24 hours then if i saw any bug i will report dude i lived ur LP kernel and this one not bad for battery but greenapple kernel was better hope see next version with better battery
Top notch kernel as always.. can u share ur best battery setting in synapse mr @duki994 because i need a little more battery saving..
Thanks :victory:
Report after first day 0f usage ) kernel is amazing ) battery life is wonderful ) my phone isn't lagging at all)) good job @duki994 ) also thanks to @somadsul for his green apple Kernel ) keep it up too or duki will understand that he beyond compression and will add features not one by one but half by half as nvidia do now )))))
P.S that was a joke
P.P.S about kernel awesomeness it's not a joke
Cheers ))

If you really need mre battery saving then replace battery. I'm serious.
I get like 1hr SoT and 80% battery. Just a bit worse than my old G2 with enormous masterpiece, Dorimanx kernel.
Use XTouchWiz and disable DVFS. Everything else sjould work much better.
I can't fully disable DVFS for exynos 5422 in kernel. It's at least 70% userspace and uses ioctl commands.
That's what Samsung did. Disable DVFS via XTouchWiz (via Xposed framework) and you're OK
Can't fix that in kernel. And it uses too much battery.
For power saving, undervolt by 25mV all cores (A7 + A15) and use ROW or NOOP sched. But performance will be at leas 10% lower for maybe 30min more SoT. Maybe !!!

Would you recommend using the PE workqueues and HMP little packing options with your kernel?
@duki994 Dude im waiting for this.. Great work.. Could u please add insecure ADB and enable ADB debugging default so as to easy to take logs while in bootloop as i was always playing with system files.

Welcome again! This is a Re-work of the Artx Kernel now working on Oreo! G3X Ultimate Kernel will be released replaced with ArtxUltra AnyKernel Installer. Like I said this is a Re-Work of the Original Kernel so, it's compiled with a more optimized Toolchain (GCC) and works better than before, just give it a try and you'll know of what I'm talking about...

Features Guide:
CPU:
- Governors: Read this
- CPU Booost: Boost your CPU Frequency on screen touch event, my kernel has per-core touch boost frequency so you can configure how many CPU's will be boosted at your preferred frequency.
- Hotplug Boost: When a Core is plugged, it gets boosted a little
Thermal:
- Core control: Enable and disable throttling, this enables the thermal engine and enable VDD restriction and core throttle. Be careful with this because an excesive overheat can reduce the device life time (and battery)
- VDD Restriction: Limits CPU voltage, limiting it will decrease temperature
- Core Throttle: Throttles CPU when enabled, this decrease CPU frequency to a lower step when it reaches a specified temperature
GPU:
- Gaming mode: The GPU will be always at maximun avalible frequency (Not always at 578Mhz because thermal engine can throttle the frequency)
- Simple GPU Algorithm: Like the name say, is a simple GPU Governor that works like simple_ondemand, I recommend more Adreno Idler
- Adreno Idler: Please read this
Don't enable Simple GPU and Adreno Idler together, this can result in a bad GPU Managament and it can generates overheat, also, those two algorithms only works on the "msm-adreno-tz" GPU governor
Screen:
- You should know how to config it at your liking
Sound:
- My kernel uses Faux123 sound control, you can set independent headphone gain that's a kernel level sound gain, so, this will not distortion your audio until you put a very high value.
Battery:
- Fastcharge: Forces Fast charging (This can reduce your battery life)
- Arch Power: Enable or disable some Arch especific power funcions for battery saving
- PowerSuspend Mode: I didn't found information about this but I know that the best option is "Hybrid"
- State Notifier: This driver notifies screen events (when you touch it). It works with Maple scheduler (You need to enable this if you're going to use Maple) and other kernel things.
- Krait C-States: Power saving settings, I recommend to disable only "C1 (Retention)" because if can cause screen flickering and slow the phone wakeup.
I/O Scheduler:
- Scheduler: Read this
- Read-ahead: The Re-ahead value on the phone memory, because the device memory is very fast, it should be at 128kB, for SDCards that are a lot more slow a good value is 1024kB or 2048kB
- Rotational storage: Treat device as rotational storage, like HDD Hard drivers, just leave it disabled, we don't need it
- Add Random: In some cases, the overhead of I/O events contributing to the entropy pool for /dev/random is measurable. In such cases, it may be desirable to set this value to 0
- I/O Stats: Like the name says, it maintains I/O statistics, if you disable it, memory monitoring apps will not work. (I don't need this so I disabled it)
- RQ Affinity: Try to have scheduler request complete on the CPU core they were made from. This can be a power saving feature
Kernel Samepage Merging:
Don't touch this if you don't know what you're doing
Low Memory Killer:
- Adaptive Low Memory Killer: Keep this feature enabled because it'll save you from random freezes (It makes Low Memory Killer aggresive dynamically when a thrashing scenario is detected)
- Low Memory Killer profile: "Agressive" is recommended, if you think that it'll close all your apps you're wrong, we've 3GB of RAM and these are the settings:
* Foreground Applications: 4MB
* Visible Applications: 8MB
* Secondary Server: 16MB
* Hidden Applications: 32MB
* Content Providers: 48MB
* Empty Applications: 64MB
Virtual Memory:
Every detail about this settings are well explained in Kernel Adiutor, but in general there's no need to touch this
Misc:
- Android logging: Disabling this can improve your phone a bit (It's not noticeable)
- Software CRC Control: Is a driver that prevents data corruptions but data blocks can lose up to 30% of perfomance, you can safely turn it off
- FSync: The kernel provides system calls for syncing single files and filesystems which flush the corresponding file buffers to storage. Disabling FSync reduces the number of I/O Opetaions which can improve the responsiveness of the device and reduce battery drain. However, disabling it increases the risk of data loss on a crash/freeze.
If your ROM with my kernel is very stable, you can safely turn off FSync and if you're on f2fs filesystem NEVER turn it off because you gonna have to format EVERYTHING if the data gets corrupt by a crash/freeze
You can always recover your phone in case of data corrupt if you're on ext4 filesystem with TWRP, in wiping section -> select which partitions to wipe -> select one and press on partition settings or more settings.
This is all for now! I'll explain each new feature that I introduce in my kernel here, thanks for reading and I happy twaking!
Spectrum Guide:
Spectrum Kernel Manager!! Thanks to @frap129!!
This amazing app let you select between 4 profiles, Battery, Balanced, Perfomance and Gaming,
all of these configured by me:
Battery: I've set various battery savings configs here, it's designed for the best battery savings and if you don't care about UI lags then this is for you
Balanced: As its name says, a very good balanced profile that evit UI Lags and the battery keeps still awesome, you can use this profile to run games without getting your phone overheating
Perfomance: This is not a pure Perfomance profile like others that simply puts your governor in "Perfomance" and things like that, this profile keeps all the UI Smoothness anytime and it doesn't drains the battery, if you're very UI Lag sensitive then this is your profile. Recommended
Gaming: Pure perfomance, play any game with this profile at maximum power, this profile keeps the FPS constants with blu_active governor, if you don't care about battery life or overheating and just want to play games then this is for you
Also, All this profiles are customizable, look at your internal storage ~/Spectrum/profiles/ folder, there's 4 files for each profile. If you don't wanna mess with all the kernel features then I highly recommend to you Spectrum!
Finally guys! We're updating our G3's!
All of my progress from the begginning to now and the future ones, has been made with my Virtual Machine in the cloud, but I'm running out of credit and I can't develop on my computer.
I'll apreciate a lot if someone can donate to me to keep this project for all our G3's alive, thanks you
Thanks for updating the kernel so I could include it in my LineageOS builds!

I'm glad to hear that
First: Thank you for this fast Kernel.
But I encountered a Problem with the external SD card. After installing this new ArtX Kernel, a Notification about a defect SD appeared, it was rendered unusable, unless formatted. That's not true as other Kernels (stock AEX, stock crDroid, stock RRmx) have no Problem with it.
As I don't want to backup all my data (about 90 gigs, as it is a 128gb card), format and recover it, it's a deal-breaker for me.
My suspicion is that the exFAT filesystem isn't implemented, as an old 64gb card formatted as vfat was accepted without problems.
Is there a solution on the horizon?
PS I don't remember the "old" ArtX Kernel having a Problem with this card, but the G3X having one, if that's any help at all.
Thanks in advance.
Addendum: As reverting back to stock AEX Kernel solved the problem, it is definitely Kernel related.

DESCRIPTION
Hey guys, I have started a custom Kernel based on LineageOS sources with 98% CAF. So I would like to share my own performance and usability improvements with minimal feature and enhancements on top. The intention is to have a minimal light-weight kernel that is very fine tuned for the device.
FEATURES
Minimal Kernel with a stripped defconfig base to be more streamlined and have less memory footprint
User space display color calibration (KCAL) with screen calibrated against iPhone 8 Plus, also helps reducing screen retention
Schedutil governor making use of EAS features with updates from Linux 4.4 and 4.12
Up to date with LineageOS sources for maximum compatibility and security bugfixes
Memory and cache subsystem optimizations, you will feel it
Adaptive LMK enabled by default
Transparent Hugepages are enabled
ZRAM/Swap partition is disabled by default
BFQ IO scheduler set by default to avoid slow-downs on task intensive scenarios
No overclocking was chosen to avoid unnecessary heat, optimizations were focused on other different areas
Kernel Samepage Sharing enabled with deferred timer by default to gain some memory usage optimizations, the process sleeps on regular basis and I've profiled it so that there's no battery drains due to it
Simple temperature controls for msm_thermals exposed
Compiled with GCC 6.x optimized toolchain and -O3 plus other hardware specific flags
Undervolted the Adreno 530 GPU voltage rail to keep things cooler
CAF Rebase on major portions of the Kernel has helped lower the memory footprint a lot
ES9218 Quad DAC automatic toggling working inside the kernel for headphone HIFI playback, please read here for details

SOURCE
V20-Kernel-Gamma GitHub Source
NOTES
Here is a GeekbenchV4 result example : http://browser.geekbench.com/v4/cpu/7618872
These is intended to be used primarily with LineageOS, I have not tested other ROM's
Since LineageOS uses a way newer Bluetooth stack, this Kernel will most likely not work on old ROM's such as ResurrectionRemix
This will not work with LineageOS 15.1, please see the other thread
KNOWN BUGS
When using v1.0.0 will fail to boot if you had Magisk previously installed. Please install something newer if using Magisk.
When using v13.0.0 - v15.x.x infrared remote control will not work.
I would also like to thanks to various people who contribute tremendously such as:
@x86cpu
@EvilHowl
@USA-RedDragon
@savoca
@albinoman887
@emdroidle
@Rashed97

Kernel Special Features:
Version Information
Status: No Longer Updated
Current Stable Version: 46.0.0
Stable Release Date: 2018-07-11
Created 2017-12-10
Last Updated 2018-10-22
CHANGELOG
46.0.0 - Started msm_irqbalance by default on boot, disabled lp11 and enabled allow mdss phy powerdown during idle screen.
45.0.0 - Smoother memlat ramp and tuned the schedTune DVR cpusets a bit for better performance overall.
44.0.0 - More deep sleep enhancements.
43.0.0 - Update to Oreo TouchScreen firmware and more MDSS PLL merge fixes that help deep sleep.
42.0.0 - Missing MDSS Oreo merges are now in place.
41.0.0 - Added IPA_WS as a default in the wakelock blocker, as well as enabling CONFIG_PM_SLEEP which if missing would in turn cause some ueventd wakeups.
40.0.0 - Disabled CONFIG_RMNET_DATA_DEBUG_PKT. Full fix for USB OTG and added missing slimport drivers. Tweaked the random wakeup values, added some extra cpusets based on Marlin's android-cts-8.0_r8/init.common.rc and fixed some BFQ IO possible hang.
39.0.0 - Disabled CONFIG_RMNET_DATA_DEBUG_PKT. Full fix for USB OTG and added missing slimport drivers.
38.2.0 - Removed LGE's battery manager alarms.
38.1.0 - Fixed potential wireless packet loss.
38.0.0 - Further tweaked the wlan_rx_wake wakelock, migrated the audio and thermal workers to power efficient queues, and added an arm64 prefetching optimization for memcpy.
37.0.0 - Better deep sleep enhancements with the charger infrastructure borrowed from the V30 Kernel Oreo sources.
36.0.0 - Full fix for 6a00000.ssusb wakelocks while keeping fast charging enabled.
34.0.0 - Added boeffla_wl_blocker to tame NETLINK wakelock, this wakelock is caused by IPC between the wireless driver in the Kernel and Android. This was the reason why when on wireless the battery would drain more compared than radio. Also disabled OTG as this keeps the phone from deep-sleeping for now.
33.0.0 - Enabled OTG.
32.0.0 - Fixed a bug from Oreo merge that causes video to go green and crash sometimes. Disabled ZRAM from the compilation rather than AnyKernel patch.
31.0.0 - Merged some V20 Oreo Kernel changes in, as well as some DAC enhancements to prevent popping, better USB PD and QC 2.0/3.0 charging code.
30.0.0 - Oreo Kernel changes in, trying to unify the Kernel to keep support for a little while on 14.1.
29.0.0 - Merged msm idle from Linux 4.4 as well as full EAS 1.4 support from Linux 4.4, reduced the memory subsystem timer ramp values for speedier operation.
27.0.0 - Enabled wifi.supplicant_scan_interval on boot, and disabled IPv4 TCP Timestamps and ICMP responses as well as CCKM fast secure roaming.
26.0.0 - Full EAS 1.4 from Wahoo (Pixel 2XL) backported.
25.0.0 - Updated EAS (schedutil, walt, fair scheduler) to be in sync with Wahoo (Pixel 2XL) latest changes.
24.0.0 - Fixed another performance regression in multi-core scores within schedutil.
23.0.0 - Screen brightness is 50% while booting to reduce heat when it is regenerating cache on boot. v22.1.0 was 25% but this was barely visible if you were rebooting under direct sunlight. So went for the safe value.
22.1.0 - Reduced the screen brightness while booting to reduce the heat of the device during cache wipes.
22.0.0 - WALT and schedutil cpufreq commit fixes backported from RenderBroken.
21.0.0 - The GPU Voltage rail undrervolt is now ~60 mV, do not see any problem and games run way cooler.
20.0.0 - After feedback on frequency utilization/distribution I've put 3 WELT commits that should help alleviate this. And enabled some extra configurations from our wireless driver for better power savings.
19.0.0 - Trimmed around ~40 mV from the GPU voltage rails, and updating the wireless stack to DHD 1.80.13 - 2017.06.22, from us997 V16a.
17.0.0 - Increased the multi-core benchmark scores.
16.1.0 - Reverted the binder to be Nougat only, since Oreo support will be on a separate Kernel anyway. Fixed the Infrared Remote Control support that I had broken, and tuned the memory scaling to be more responsive.
15.0.0 - More audio fixes. This audio CAF merging has fixed the speaker-phone that suddenly stops recording or suddenly stops recieving audio from the phone call in LineageOS. Also have increased the schedutil timer values to be similar to the Pixel 2 XL (Wahoo). And finally have fixed a CONFIG_LGE_PM_LGE_POWER_CLASS_CHARGER_SLEEP problem, so that the charger module now sleeps better and uses less power in idle.
14.0.0 - Updated WALT (Window Assisted Load Tracking) fixes aggregated by RenderBroken. Fixed an audio bug introduced in 13.0.0 where headphone insertion could change the sampling rate of other audio sessions. Changed again the schedutil timer values to favor benchmarks a tiny bit and increased the external SD read-ahead and minimum number of requests so that there is better merging when using slow SD cards while keeping the internal storage device in a low-latency configuration.
13.0.0 - Merged CAF audio upstream changes and enabled transparent hugepages.
12.0.0 - Tuned the memory subsystem frequency scaling parameters further down to focus on batter savings as well as the EAS timers.
11.0.0 - Added cpuidle optimizations to idle more, bumped up the memlatency trigger.
10.2.0 - Reintroduced back QuickCharge 2.0 and QuickCharge 3.0 fast charging support into the Kernel.
10.0.0 - Bumped up the Kernel to version 3.18.71.
9.0.0 - Full arm64 arch CAF update done to the Kernel based on CAF LA.UM.6.5.r1-05300-8x96.0. Added support for H918 variant too.
8.2.0 - Partial update to get the Kernel in a big percent that of CAF LA.UM.6.5.r1-05300-8x96.0, no bugs introduced and using a CAF / LineageOS kernel base. Using the binder interface that works both for Android Oreo and Nougat to be prepared for Lineage15. Also fixed a bug that I had introduced in previous versions related to wireless access point, hence why I had pulled versions 7.x from the server.
4.1.0 - Reintroduced into the LineageOS kernel the partial-update in the panel, to gain some power savings and overall performance feeling when refreshing the panel and screen elements.
4.0.0 - Raised the EAS schedutil timers and the memlat governor threshold to kick in faster. This will bring up the responsiveness to similar levels to HMP even when still using EAS. Brought back KSM after profiling on battery utilization, it doesn't hurt as long as a the timer value is between 4000.
3.0.x - Bugfixes and testing with Magisk compatibility, I think there are no more compatibility problems with Magisk after this, had to remove KSM for testing.
1.0.0 - Initial version, with KCAL, and streamlined defconfig based on cm-14.1 kernel sources and minor commits on top.

DESCRIPTION
Hey guys, I have started a custom Kernel based on LineageOS sources to get and share my own performance improvements up and adding minimal feature and enhancements on top. The intention is to have a minimal light-weight kernel that is very fine tuned for the device.
FEATURES
Minimal Kernel with a stripped defconfig base to be more streamlined and have less memory footprint
User space display color calibration (KCAL) with less blue tints by default
Schedutil governor making use of EAS features
Up to date with LineageOS sources for maximum compatibility and security bugfixes
Memory and cache subsystem optimizations, you will feel it
Adaptive LMK enabled by default
ZRAM/Swap partition is disabled by default
BFQ IO scheduler set by default to avoid slow-downs on task intensive scenarios
No overclocking was chosen to avoid unnecessary heat, optimizations were focused on other different areas
Kernel Samepage Sharing enabled with deferred timer by default to gain some memory usage optimizations, the process sleeps on regular basis and I've profiled it so that there's no battery drains due to it
Compiled with GCC 6.x optimized toolchain and -O3 plus other hardware specific flags
Re-introduced stock thermal values and engine for a safer device operation

I don't know how 'in-depth' testing I can do. But I'll be willing to do what I can!
I'll be flashing this soon.
I'm on Desolation ROM, VS995. I'll report back. Thanks for your hard work!
Edit: not necessarily a problem, but it has static on boot.

Oh, I didn't compile specifically for VS995 so it will have static on boot. Since these two are mostly the same devices I might give u a VS995 Kernel next week with that static gone.
Here are some Geekbench results in case anyone is interested : http://browser.geekbench.com/v4/cpu/5506983
Great to have someone finally building an AOSP kernel!
Any chance you'll be compiling for the H918 sometime in the future? No worries if you aren't. I'm just curious =p

That sounds great! I'll look forward to it! But I'm about 12-14hrs in the kernel now, and so far so good! With normal usage.
Have updated Kernel to 1.1.0 version with two minor changes that improve the performance by quite a big. Figured out the OP3 and the Marlin Kernel was using 300 Hz tick timers. But for some reason our Kernel was only using 100 Hz tick's. So two changes in this version.
1. Enable high-res timers for schedulercks
2. arm64: hz: make it configurable

Plus I have decided to go on and change the perfd binary again. I was not aware how much of impact this has to EAS and the fluidity, since with EAS the input freq boost in the Kernel is now gone. You can read more about it here : https://github.com/EAS-Project/android_device_voxpopuli in the README.md. I am not yet using 100% of the capabilities of Vox Populi Power HAL but a lot of features from it turned off for now.

Most likely yes, but after I polish a few features and once I am 100% happy with the performance
Hmm... Oddly enough if I install I get stuck into a boot loop. Not even a LineageOS boot animation. I am and will continue to use Magisk, even flashed all 3.

Oh shoot... I haven't tested it with Magisk on top myself, I wonder if I removed some thing in the defconfig that Magisk needs... Mmmm, both versions give u that same outcome ? Thx for the report!

I only tried the latest one. I did not try without Magisk though or the older version, the all 3 reference was all 3 files you had. gamma/vox/thermal.
I noticed in your thermal, that the camera files are the same as Lineage, so you could take those out. I also took out the mixer one as I bumped those VOL up as it was hard to hear on calls without it. If you do find any adjustments that the op3 or marlin did, we might be able to get those into the Lineage msm8996 kernel. Ideally, the commits from op3 in the Lineage tree, then I can cherry pick it to preserve history. I'm all for getting things into Lineage where we can.

So I got home to try just in case @x86cpu and I was able to flash Magisk-v14.5(1456).zip after all of the 3 files had been flashed on my system and it booted fine.... so I've re-uploaded the Kernel as v1.1.1 in the downloads section just in case...
Wiped /system (as I had su from LineageOS flashed before)
Flashed system with lineage-us996-*.zip
Flashed OpenGapps
Flashed perfd update (2nd of my zips)
Flashed the 'hotfixes' (3rd of my zips)
Flashed gamma-kernel (1st zip)
Flashed Magisk-v14.5(1456).zip
Hit reboot
If you can let me know if the v1.1.1 version works on your side then I can blame the bad upload. If not I can do more experiments to see if there is some other condition that depends on the order of flashing with my AnyKernel approach... and then I can try and replicate and fix it , please do let me know...
UPDATE: I am able to hit the failure now @x86cpu... let me see if AnyKernel needs any update or something to allow to re-install the Kernel if Magisk is already pre-installed. In order to hit it I had to:
Wiped /system (as I had su from LineageOS flashed before)
Flashed system with lineage-us996-*.zip
Flashed OpenGapps
Flashed perfd update (2nd of my zips)
Flashed the 'hotfixes' (3rd of my zips)
Flashed Magisk-v14.5(1456).zip
Flashed gamma-kernel (1st zip)
Hit reboot
Essentially flashing the Kernel last... which might be a common thing that could happen, let me polish that up...
I've uploaded flashable-us996-gamma-kernel-v1.2.0.zip now with an updated AnyKernel script that seems to now be working even with Magisk installed previously. Thanks to @x86cpu for reporting this bug.

I just installed the v1.1.1 before the fix. So. In other words before I saw this update, I just flashed it with no wiping, Desolation rom, and it booted fine, it's just now, in Magisk I can't pass cts or basic integrity. I'll try your updated method and see if that fixes the problem.
Edit: did the above steps, minus wiping twice and flashing the hot fixes twice. Rebooted it. And now I can successfully pass safetynet on the latest gamma kernel!
Edit#2: false hope, my apologies, safetynet apparently isn't passed.
Edit#3: okay. I had a blonde moment. I forgot to wipe my dalvik. It passes now.
What do the HAL's do? And what order should I flash the zips?

Click to expand...

The order doesn't matter as they are independent. And I would suggest you read about the EAS perfd HAL in here : README.md
However keep in mind that I haven't implemented all of the VoxPopuli features from the HAL in the AnyKernel as it needs some SELInux permissions updates (which I can do later on). But without all of those enhancements it will behave like the Pixel HAL.

Caution:
I am not responsible for anything that happends after flashing the work provided here.
Sharing is caring, so according to the (much unwelcomed) rule 12 you can use my open source on GitHub without my explicit consent or credits. But this is where the caring stops as I do not allow you to use any of my own provided files (except for unmodified stock files). Section 3 of this rule states that you can try to bypass my explicit consent by releasing it as your own when you succeed to make significant changes to the work.
Goodluck and happy CopyMaxing.

Changelog
R28
- Updated to DSF source
- Improved performance and efficiency.
Old changelog:
V1 - Initial XDA release, based on 2nd test 38
R2:
- Fixed freezes that was caused to a minority of users on particular roms
- Fast charging fixed to work for everyone
- Potentially improved battery life at the cost of slight overhead
R3:
- Fixups and hiccups
- GPU control added in Synapse
R4:
- Removed Synapse and OC, mtweaks is good enough
- Based on Test 50
R5:
- Oreo release
R6
- Merged N8 March Oreo source
- LED fixed
- WiFi blob detection fixed (still requires a few files due nvram path..)
- Faster booting
- Tweaked for better idle drain and battery life
R7
- Bug fixes caused by N8 merge
R8
- Rebased the kernel by filtering out bad changes for battery life, performance and so on.
- Updated to latest CRD source
- Fixed LED (hopefully definitely)
- Fixed WiFi (works like stock kernel)
- Mount system earlier to boot faster
- Added overclock for cluster1
- Fully Permissive (no longer fake enforcing)
R9
- Removed lots of useless stuff -> faster kernel and less size
- Still CRD7 based with CREF ramdisk (CRED source has worse battery life according to my groups experience)
- More stable LED implementation
- Removed Fsync/CRC toggles because data stability is way more important than this benchmark cheater
R10:
- Fixup of R9
R11
- REQUIRES NEW MODIFIED TWRP FIRST
- New fading led approach -> enabled by default and not bugging anymore. You can control it with Mtweaks V2.9
- Quotas enabled, which works thanks to the new TWRP. More info
- Some fixes and optimizations.
R12
- REQUIRES NEW MODIFIED TWRP
- Middle of rebase, not done yet..
- Manually updated to CRF
- Added CRGB support
- More unification work done (fixes Samsung's screw up by delaying probe after booting up, which would result in an unresponsive lockscreen until init occured.
R13
- REQUIRES NEW MODIFIED TWRP
- Merged CRGB source update (seems the R12 fix was short lived)
- Re-added changes I forgot for R12, e.g. Drivedroid support, OC.
- Fixed WiFi-calling as confirmed by @bininga59
R14
- Requires modified TWRP - See post for explaination
- Almost done rebasing
- Fixed bad code using GCC 7.3 (also fixed booting compiled kernel with 7.x/8x toolchains due bad alignment)
- Reduced kernel overhead, improved security (fully disabled debugfs)
- Removed ability to overclock the big clusters
R15
- Added TWRP patcher: During installation it will detect unmodded TWRP and modify it. If it detects a modified TWRP it will skip this step. If you care for MTP in TWRP then you still must flash the TWRP provided in post #644. The only reason I added this script is because many fail to follow instruction (flash modded twrp and kernel/rom).
- CRGH source update
- Re-added GPU sysfs and underclocked to 112Mhz
- Some under the hood optimizations for more stability, better consumption and idle improvements.
- Probably N9 port ready (untested)
- Still rebasing...
R16
- Linaro 7.3 compiled
- Re-added big cluster OC
- Fixed Gear VR & recording call bugs
- Not N9 ready (requires more ramdisk changes + still waiting for a working port)
R17
- Requires modified TWRP (due to proper Oreo support) -> See post 644
- CRI based
- Forgot the rest
R18
- CRK source drop merged
- Improved touch latency
- Updated LZ4 module to 1.8.3
- Other misc improvements; e.g. improved idle consumption, bug fixes, smoothness, snappiness etc.
R21
- Last kernel to support Oreo.
R23
- Properly upstreamed to 4.4.176 with no cpu bugs etc.
- Compiled with GCC 8 and fixed all buffer overflows -> should improve stability but also has an overall positive effect
- Better idle -> Don't take my word for that as I don't know how upstream will affect the change
- Touchscreen backport from Pixel 3 for better touch latency on S8 devices (too bad S8+ uses a different panel)
- Re-added overclock abillity
- Other minor optimizations that positively affect performance and battery life
R24
- Updated to latest DCSB source
- Upstreamed to 4.4.178*
- Sound control mod backported (requires latest Mtweaks)
- Wakegestures backported: Doubletap2wake, sweep2sleep, sweep2wake.**
- Fixed permissive state to work with banking apps (no reboots)
- Fixes on top of fixes and optimizations that will affect performance and idle drain.
* Still indecisive about upstream
** Enabling gestures will kill AOD touch and hard press to wake
R25
- Dropped upstream as I always was convinced it resulting in worse battery life.
- Switched from Zswap to ZRam.
- Added overclock abillity for little cores to 1898Mhz (fixed this possibility)
- Big cluster min clock is set to 858MHz
- Added GPU OC abillity to 572MHz
- Compiled with my custom compiler to target exynos-cortex (big.LITTLE)
- Some other minor optimizations to improve idle and battery life.
R26
• Compiled with custom GCC 9.1.1
• Updated to the latest available source for S8/N8.
• Selinux: now you can switch enforcing by writing "setenforce 0" in a terminal or by using an app like Mtweaks. This can be useful incase your banking app requires an enforced phone (e.g. rebooting)
• Updated moro sound control: fixes unlinked L/R control and resets
• Wake gestures: added a proximity state check so that an enabled wakegesture cannot wakeup the phone when the proximity sensor is active, like during a phone call.
• Other changes to improve performance, reduce kswapd usage and hopefully preserve a bit more battery life.

FAQ
Q: Does this support non stock roms?
A: The kernel does not support ports, e.g. note 9 port, while it may have the possibility to support note 8 based roms. This kernel will never have AOSP support.
Q: Can you add X to the kernel?
A: No, this is a personal kernel and therefore won't have what I don't want. This is a take it or leave it kernel, so if it doesn't have Spectrum, Flickerfree etc. then I'd leave it.
Q: I lost root
A: The zip contains no root, because rooting is optional. You need to flash Magisk manually after flashing the kernel.
Q: I have a problem!
A: Make sure you use no Xposed framework. If we have that cleared, please post a dmesg and last kmsg of the moment right after the problem occured. You can use Syslog app for that from the play store.
Q: Want my benchmark score?
A: No this is no pissing contest thread who can reach the furthest.
Q: Can I donate you?
A: No, I am doing this to improve my phone in the first place and sharing takes 2 clicks. Not into the money business by putting up a big ass donation button in the first post. Go spend your money on family or yourself instead.
Which build do it base on?
good!!!
Great kernel!!!
Glad to see it here
Best kernel about. Its been a pleasure testing and meeting you bro.
Running this kernel for ages :victory:
This is by far the best kernel for me
This is really good work
Never wanna miss it
Great work I will surely stay forever

So far nobody reported a freeze in the test versions, so I am curious. Do you own a S8(+) F/FD/N variant? If yes, reboot directly in TWRP on the freeze and make a dmesg + last kmsg.
