No Gravity Kernel 2.0 + 4.0 App Trailer
Why is it called NoGravity kernel?
The OnePlus company decided to give the Snapdragon 810 V2.1 to our device. It comes with a little increase in GPU clock speed (from 600MHz to 630MHz) BUT it also comes with a CPU downclock going from 2.0GHz to 1.77GHz on the big cluster to avoid overheating issues. No overclocked kernel has been made for PIE/OREO so this is the reason why I made this kernel. This Kernel is for Performance but it still gets descent battery life due to some added features (see below).
The Kernel will boot using stock (OnePlus 2) CPU frequencies that correspond to the Balanced Profile. Other profiles for battery, performance and gaming can also be switched to in my 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.)

Most of my work will be on Energy Aware Scheduling Kernel version since NGK is really solid and stable,,,
This kernel works on Android 10, PIE and OREO ROMs.
DO NOT FLASH ON STOCK OXYGEN OS!
Initial boot might heat up device a bit, which is normal - Let it settle
I recommend before coming to conclusion, give it at least 2 complete charge cycles and then raise any issue.
Max fully stable overclock is Little/Big 1.8GHz/2.1GHz
Both max 1.9GHz and 2.2GHz may be unstable and are not reacheable using app profiles. They still can be reached using the max overclock toggles the app provide.

More info on EAS and the specific implementation for OnePlus 2
EAS | Energy Aware Scheduling
Notice : I will not tell you everything about it.. I'll just do my best to summarise it up and, most importantly, say what's the implementation of it in my kernel compared to newer phones... I don't know everything and may do some mistakes (english mistakes included ) if I do, let me know but still should be on track. I will highlight important words in bold. Also for better kernel tuning, please use my app as its made for our specific implementation of EAS.
Intro: Well Google mostly wanted a better/smarter algorithm to ramp up frequencies than the current cpu-boost driver.. So they started to make the kernel smarter on their 3.18+ kernel seen on Pixel Phones. They wanted to port EAS to their previous phones (Nexus 5x and 6p) having 3.10 kernel like the OnePlus 2 but they didn't.. They started porting it with a pretty basic implementation with a bad energy model, a pretty old version of the battery oriented Per Entity Load Tracking, a pretty basic Schedtune support too and the old Sched governor instead of the newer SchedUtil governor used on current/newer phones. That basic implementation was actually the first releases here on XDA before 3.0 update.
Energy model: At the base of a good EAS implementation there's an Energy Model containing compute capacities and energy cost tuples for each Cluster (big.Little). That way, its possible to estimate the cost of task placement on CPU. Hmm okay that was a big sentence here.. Well to summarise it up, some tasks need more compute capacity to run nicely (smoothly,fast,etc) so need more power which will cost more to run and depending on the task it may need to run on the Big cluster. I say that the kernel is smarter that way, since it will try to set tasks on cores that needs less power to run while still being fast enough for the task. It will also decide to use a shallow core instead of waking another from deeper since the energy model also specify wakeup costs.
What I did for the Energy Model until now: Since the Angler energy model that was used in first releases was pretty bad, I converted it to a frequency / cost model instead of capacity / cost which is now much easier to manipulate instead of speedbins. I then recalculated costs for each frequencies with some graphs including voltages for every frequencies to determine cost for both Cluster. For overclocked frequencies, I had to extrapolate/interpolate trend lines I had in those graphs. That way, we now have an Energy Model that corresponds better to our OnePlus 2 device. Some changes might need to be done later on, but it seems okay for now.
Sched Governor: EAS's Sched or newer Schedutil both use SMP -> Symmetrical multiprocessing instead of previous HMP -> heterogeneous multi-processor found for interactive, ondemand, etc... HMP and SMP both have in mind that multiple CPUs are running, but on SMP no CPU is selected as the Master CPU.. both CPU cooperate as friends.. Well we all know there is a big difference between our little and big CPU and this is why the governor is not alone in EAS..On the other side, HMP knew exactly which cpu was more powerful and while this is good since its easy to implement and fast, this is why its not too battery friendly..
What I did to Sched governor until now: Well no specific feature comes to my mind, but it got optimised alot by backporting amd upstreaming some part of it from higher kernel versions (mostly 3.18)..
Schedutil Governor: Schedutil is the governor every phone uses right now by default I guess. Sched is not even there anymore if I'm not mistaken.
What I did to Schedutil governor until now: Shedutil got backported from 3.18 to the kernel. From my tests, it's been more stable than Sched for below reasons:
o Took less time for the kernel to settle after booting.
o Frequencies stay low and do not jump everywhere when simply looking at the screen.
o Improved latency
Its now possible to switch between them using my app. I wanted to make a comparison between both but couldnt find enough info on them to really tell you precise differences. I can only say Sched is predecessor of Schedutil so I assume Schedutil can only be more efficient.
Load Tracking: Whether its PELT (Per Entitty Load Tracking) or WALT (window assisted load tracking) both increase efficiency since they do not affect frequencies directly and instead of just placing tasks on any cpu it analyzes it and the amount of energy needed for it is estimated. This smart way of doing things make system quicker since it can run more tasks for less energy. This is what EAS is all about.. smoothest UI possible with lowest impact on battery. PELT is more battery friendly as it ramps frequencies up and down slowly.. On the other side, WALT ramps up and down really fast making UI smoother and snappier since every task is done as fast as possible so cpu can idle and go to sleep faster.
What i did to load tracking: I optimised PELT and added WALT.. Its now possible to switch between them using my app.
Comparison between WALT & PELT
Souce: https://fr.slideshare.net/mobile/linaroorg/walt-vs-pelt-redux-sfo17307
Frequency ramp up
Frequency ramp down
As you can see, WALT ramps up way quicker than PELT leading to smoother UI. Also tasks are done more quickly. On the other side, it's also possible to see that PELT may be better is some specific use cases as when another job needs to be done a little after due to it not ramping down frequencies completely. This way, WALT would need to ramp up again while PELT would be ready.
Schedtune: Exposes 2 tunnables to userspace: schedtune boost and schedtune prefer idle into cgroups. There are actually 4 cgroups background, foreground, rt and top-app. The first tunable (schedtune boost) takes an integer between -100 and 100, 0 being the default value meaning the most energy efficiency which means that it will be using the lowest frequency to do what it needs. An higher value will add an % offset to the normally used frequency. The second tunable (schedtune prefer idle) when set to 0 (default value) will simply do what EAS says it to do. When set to 1 it will prefer setting tasks on idle cores to reduce latency. Pretty easy to say the second one is less energy efficient.
What I did to Schedtune: Some improvements to it have been added for sure since first release. I've set top-app
default value to 1 instead of 0 to bias tasks on big cores. This way, it also improves latency for Dynamic Schedtune Boost.
Background has been set to -10 to reduce its impact. Gaming and Gaming+ profiles are using more aggressive values so they are not recommended for other tasks than gaming as this may give you higher battery drain during normal usage.
Dynamic Schedtune Boost: It's pretty easy to understand and its a pretty nice feature made initially by joshuous on the OnePlus 5 if Im not mistaken. It simply sets a user specified value to schedtune boost dynamically a cgroup so it can go back to 0 afterwards to not hurt battery. It's mostly used in cpu-boost for input boosting.. Then why not just use the input boost that worked well on HMP? Well to that I would say: how do you know the input boost frequency value you've set is the correct one for what your specific usage? Input boost will boost to a user specified value but what if that value is okay for chrome but too high for simply scrolling in a text file? Well that's it.. EAS is able to find the frequency needed depending on usage + the dynamic boost it will simply make things faster and smoother by adding a positive offset to the frequency used but dynamically so it can revert back to 0 afterwards and save battery while phone is actually doing nothing or when your simply looking at the screen.
What I did to dynamic schedtune boost untill now:Well I added it to our kernel by backporting the feature from a pixel kernel and adapted it to our phone. Due to some limitation we can only dynamically boost top-app.. at least for now.. I could add other cgroups quite easilly but its not really needed as top-app is the most important/effective one. I'll add more later if its actually needed.
To tweak it: Use the EAS page in my app... make sure you don't set any frequency boost in any kernel manager, tweak input boost ms and dynamic stune boost value. Note: enabling Dynamic Schedtune Boost in my app will automatically erase any previously set input boost frequency so it works correctly.
PowerHAL: For proper EAS people say it needs proper PowerHAL.. The kernel itself cant make what a PowerHAL can do since it cant read some userspace events and all. Lets say boost on input touches can be done with a good PowerHAL so less job is done by the kernel.
What I did for PowerHAL untill now: Well I'm aware of what a PowerHAL could bring tho no PowerHAL has been done for EAS on for old kernels.. That doesn't mean I couldn't modify a newer one to fit our phone but I made a lot of tweaks in the kernel directly to prevent that. A PowerHAL is compiled with a ROM directly so could be harder to replace. So what I did is put some nice features to mimic PowerHAL behaviours like Dynamic Schedtune Boost, DevFreq boost on app launches, fingerprint boost and more nice features directly in kernel that allows (for some of them) to be tuned by the user.
More features and development can be seen in changelogs.
If you have any questions feel free to post them. If I made any mistake feel free to correct me.

fully working for everyone will do more testing if you want that freq back
Install this Kernel on AOSiP
All fine so far seems very smooth and stable.
The temperature also looks good. I will continue testing but I think this is a promising project. Thank you:good::fingers-crossed:
Does it have under volting support?? So that reducing the voltages can also reduce temps while using the device at OC frequencies.

Thanks for trying my kernel! What a surprise it worked on LineageOS I didn't expect that, I am compiling right now the 1.5 update that will work on LineageOS and AOSP.
Thanks for Update
It is a safety reason that the 1.9GHz stage for little is eliminated. With me the V1.4 ran without problems at 1.9GHz.
V1.5 little max frequenzie is now 1804MHz but its enough. Also min Step 302MHz is fine
Sot is fine with all time overclocked
V1.4 and last time with updated V1.5

for me too it ran without problem, the reason is that it wasn't working for everyone. Some had bootloops. We'll see in the futur...

Intro:
This is the first kernel I've ever developed. I just started developing on android a few months ago so I'm brand new to this. I don't consider myself a developer, I'm just good at figuring things out, all credit goes to the real hard workers coming up with original ideas like Franco, Imo, Flar and Faux. Initially this was built as a kernel to compile with my ROM I'm working on but I decided I would let others get a chance to use it as well. I hope you like it and I won't be offended if you hate it. All ideas are welcome and I'll try to help as best I can. If you wish to use this kernel in a rom , feel free! Although I would love it if you let me know just for my own curiosity.
For those looking for a similar experience, but much closer to stock, I suggest giving Zen Kernel a try!
Goal:Keep kernel as lean as possible while adding certain, desirable features and optimizing for maximum performance and battery life. The default settings should be optimal for a balance of battery and performance without a need to tweak.
Disclaimer:If your phone blows up, its not my fault. If your phone somehow gains perpetual battery life, I'll take full responsibility.

FAQ's
1. How Do I Enable Mako Hotplug?
To enable mako hotplug use your favorite kernel control app like faux or trickster. As of 1.8 it is the default hotplug. In trickster you have to turn off both mpdecision and intelliplug. In faux you need to simply select User Control in the Hotplug Section. The hotplug can be configured using Franko Kernel Updater App.
2. Does This Work With CM12 Theme Engine?
Yes, this works with CM12 Theme Engine and should work on all ROMs properly.
3. How Can I Force All 4 Cores Online All The Time?
First you must enable mako hotplug. Then you need to use Franco's kernel updater app or another app that allows you to tweak mako hotplug settings. In fku app select CPU manager then hotplug control. Change load threshold to 0. Additionally if you just want to make it use 4 cores more often. Lower this number below 80 as desired. This should also be possible to tweak via terminal however I've never used that method.
4. Does This Have D2W, S2W, etc?
Yes, those are part of LK which means they are include in this kernel.
5. Help! I think its making me bootloop!:
This may only apply to specific ROMs and I'm unsure ofnwhy it would change anything but users have reported this to fix the issue. If you are trying a fresh install of a ROM boot on stock kernel first, reboot, then install this kernel.
6. You Broke My Phone! Fix It!:
It will be quite hard for me to figure out what is going on if you don't provide details and a log of what happened. To get a log use any file manager with root support and navigate to sys/fs/pstore I then need the console one.
7. What Kernel Tweaking App Should I Use? What About For Tweaking Screen???:
I now Use synapse as my goto app for kernel tweaking since version 1.3. To control the screen I use the app made by Savoca who created the color control we use http://downloads.codefi.re/savoca/kcal
8. Why Add Zram? We Already Have 3gb Of Ram!
Zram was added in build 1.0 as an experiment of sorts to see how much is was actually being used. V 1.0 introduced a bunch of tweaks to the kernel that essentially make it use more ram in order to give better battery life and performance. Zram was put in place to offset this in a way.
9. Wut Is A LZ4?
LZ4 is a compression algorithm used by the kernel. LZ4 is currently the fastest supported option in the Linux kernel and had to be ported from upstream. It is significantly faster than XZ compression which is what we used prior. The downside is it results in slightly larger file sizes due to a lower compression ratio. However with modern hardware this should be moot. The gains should theoretically be noticed as a general performance bump. Boots should be faster. IO should be marginally faster. Anything that's compressing or decompressing stuff, such as ZRam and encrypted devices will utilize this in a big way. Because its compressing and decompressing so much faster it can also be assumed it is saving battery via less CPU cycles.
10. What Is Strict Aliasing And Why Should I Care?:
One of the big things Linaro does with improving Android's performance is fixing violations of what's known as "the strict aliasing rule." A pointer is said to alias another pointer when they both refer to the same location of memory. This is OK and not an uncommon thing to do. The strict aliasing rule is that pointers of different types should never refer to the same location of memory (aka alias each other). Strict aliasing allows a compiler to make some assumptions when compiling and optimizing code that it otherwise couldn't. It's actually one of the biggest optimizations you can do and it is fairly hard to add which is why most people don't. Here's a nice read up on it http://cellperformance.beyond3d.com/articles/2006/06/understanding-strict-aliasing.html#benefits
11. Come on man. 35mhz is pointless bro!:
A common misconception is that if two frequencies run at the same voltage. They use equal power. In fact this couldn't be less true. The equation for power draw has four variables. Two of which are frequency and voltage. Essentially it is the frequency multiplied by the square of the voltage. Then you would take that and multiply it by a few other things such as capacitance. However that is irrelevant for our purposes as it will not effect the relative results. This means that 35mhz running at 500mv will use about 3x less power than 98mhz at 500mv. Now we say well what about compared to 300mhz? I can stably run that at around 650mv. Maybe slightly less. This equates to about 15x less power usage at 35mhz. Well now that we know that. Who cares? Its not like 35mhz will even get used. Its too low! I beg to differ. I would almost guarantee that if you are not running mpdecision 35 MHz will be within the top 3 most used frequencies. Most likely the top used below sleep. And every time it uses that over 300mhz you are saving 15x the power. Additionally 35mhz also runs at a cache frequency of 35mhz as opposed to 300mhz cache frequency and runs a lower bus speed/voltage saving additional power. The same goes for 98mhz. Hope this helps clear things up.
12. How Do I Disable BlueSleep Wakelock?
Open terminal emulator app. Type su then hit enter then type echo 0 > /sys/module/wakeup/parameters/enable_bluesleep_ws all on one line. It won't say anything but if you turn on Bluetooth and check your wakelocks you shouldn't see the wakelock there anymore. This needs to be set on each boot currently. If you experience Bluetooth connectivity issues don't disable this. To enable it again either reboot or run the same command with a 1 instead of a 0.
13. How Do I Use MultiRom???:
To use multi ROM first you must download the MultiRom App from this location http://tasemnice.eu/bordel/MultiROMMgr-v1.180.apk the play store version doesn't work with shamu yet. Then you will need to open it, go to settings and tap the version number until you are a developer. Then click override manifest URL and for manifest URL enter http://tasemnice.eu/multirom-test/manifest.json the. Go back to the main page. You should now have MultiRom and recovery boxes checked. Click install, reboot etc. To install a ROM. Download a ROM you like, go to twrp, click advanced,MultiRom,add ROM. Select internal storage and the Your zip file. Flash it but don't reboot! After that go back and select "list ROMs" select the ROM u just flashed still and click flash zip and select your gapps,supersu etc. After that simple reboot and select your new ROM on boot use the MultiRom app to manage your ROMs.
More will be added as they come up and I think of them.
Configuration Guide:
The following can be done using your favorite kernel tweaking app. I use synapse.
Clock Speed:
To begin I prefer to leave my max clock speed at the stock 2.649ghz. Set min CPU as low as it can go. As of current release this is 35. For the adventurous you can try 2.88ghz. Often I bump the voltage 12mVolts on 2.88 to be safe.
To find your CPU binning run this command in terminal emulator OR look at the first page in synapse near the bottom:
su (enter)
cat /proc/cpu/msm_acpu_pvs (enter)
(Put a space between cat and /proc)
note that the number may be displayed at the beginning of the next line.
It will then display a number from 0-15. 15 being the best. Don't stress over it too much if you score low, its not the end of the world. It just means you need marginally more voltage to run each frequency.
GPU:
As of Alpha 1.3 the GPU can now be over clocked to 700mhz. This is completely optional. To verify your over clock change the GPU governor to performance and see if it spikes to 700 every so often. If it does it worked! If it doesn't you may need to set the frequency to something else then back to 700 again. It remains to be seen what kind of benefits the GPU over clock will give but it is there for those who want it. The recommended GPU governor is the stock msm adreno one. If you encounter lag in games you can try changing it to performance temporarily while playing that game. Simple on demand is a more performance oriented governor.
Governor:
Most people will probably want to just leave this set to interactive. Its a really good governor that is being actively devolped by CAF, Google, and Franco. It also hooks into Francos CPU Boosting interface. Its "smarter" than OnDemand and generally considered to offer better battery life. If you want even more smoothness some consider OnDemand to provide a bit better performance, however you may get slightly worse battery life. This is because OnDemand ramps up to max frequency when there's is load put on the CPU and then slowly works its way down. Interactive scales through the frequencies on the way up and down which saves battery life but prevents it from jumping to max speed as fast if it is needed. Simms22 recommends using the OnDemand governor with "upthreshold" set to 98 and the sampling rate set to 15000. That is the default setting of the Trinity Kernel. Mistertac made the great suggestion of turning the max screen off frequency down to 600mhz if using the interactiveX governor. This will prevent any misbehaving apps from keeping CPU ramped up while screen is off and give better idle drain. The actual number you would have to type in would be 652800 for the screen off frequency. The Conservative Governor is greatly modified by franco, Its no longer a super slow governor as it once was. It also hooks into his cpu boost control interface meaning you get cpu boost when using it. Conservative prefers the lower frequencies, however so if you find yourself having lag, you may want to switch to another.
PowerSuspend:
The only working options in V1.6 of the PowerSuspend driver are lcd_panel and Userspace which can be found in the miscellaneous section of FauxClock. I suggest leaving it at the default choice of LCD_PANEL. In FauxClock if you navigate to the cpu idle/stats area you will be presented with more options. You should see a list of C-states. For example C0: wfi and C1: retention. These are essentially low power states that the cpu can enter to save power. The higher the C number the deeper the sleep. Last I heard, the optimal configuration was to enable C0, C1, and C3. Paired with lowered Retention voltages, this should give you a very low idle drain.
Hotplugging:
Next go to hot plugging section and disable MPDecision(make poor decision) and enable intelliplug or, enable Mako Hotplug(Franco's) by either selecting user control as your hotplug, or disabling both mpdecision and intelliplug. Tweaking for them is split up below.
IntelliPlug:
FauxClock allows you to further configure intelliplug. If you want more battery set it to Conservative (4) mode which will hotplug the CPU more conservatively and save you battery, essentially this means it will use less cores if it can. For most people, leaving it on Balanced (4) mode will be fine. If you want further battery savings you can set it to EcoPerformance (2) or even EcoConservative (2) which will only use a max of 2 cores. IntelliPlug is able to use a single core unlike Mako Hotplug.
Mako Hotplug:
As far as I know the only way to tweak Mako Hotplug is either through the terminal app, synapse or through Francos app. In Francos app select cpu manager, then Hotplug Control. The main one you will need is load threshold. The default is 80. The higher this number, the more load the cpu needs to be under before it will plug the 3rd and 4th cores. 80 is actually pretty good value for most people and it will use the extra 2 cores when it really needs them. If you want to force all 4 cores on for whatever reason, you can achieve this by setting the load threshold to 0. This will effectively disable hotplugging. Of course you can always find a middle ground as well.
Via Terminal:
The sysfs interface for mako hotplug is...
/sys/devices/virtual/misc/mako_hotplug_control
To adjust... Use echo commands...
Ex:
echo 0 > /sys/devices/virtual/misc/mako_hotplug_control/load_threshold
The above command would set the load threshold to 0.
Thanks Rignfool!
Voltage Control:
Next go to voltage control. I'm a Bin 5 and I can use a 48mVolt undervolt without becoming unstable. Rember! Never set voltages to apply on boot until you have tested them for a few hours first! Most people can probably get away with a 36mVolt undervolt and nearly everyone should use at least a -24mVolt UV. Also remember that if you are running an over clock you may not want to undervolt that frequency. If you find yourself running into freezes or random reboots remove the undervolt!
Thermal:
This kernel comes with the latest IntelliThermal Driver from Faux123, which is a highly configurable thermal driver, as well as Franco's Thermal Driver which is the stock option. It is recommended you use IntelliThermal over Franco's if you wish to customize the values. Change this option under the Thermal Manager section of FauxClock. The optimal settings that I have found are 70 degrees for frequency throttle, and then somewhere between 70 and 80 for core throttle temp, depending on how safe you want to be. Stock is 80 degrees. Leave all cores checked for both frequency throttling and core throttling. I also leave on GPU Thermal Control, but if you encounter periodic lag in games you may wish to disable it. I also leave Core Thermal Control on as well, though I'm not entirely sure what it does lol. Also FYI, the sliders beneath those two options are showing you the current status of them, they are not sliders you can move.....trust me...I tried for like 5 minutes before I realized and felt like a moron....
I/O Settings:
For I/O scheduler select FIOPS. FIOPS is superior to the other schedulers in nearly every way. It is a scheduler designed for flash storage which is what our phones use. My testing has shown that 1536 is the best readahead buffer. Less or more is detrimental.
ZRam:
ZRam is something designed to optimize the ram of a device. What typically happens when a device runs out of space in ram is it is forced to use something called swap. Swap is normally a partition of a hard drive or ssd depending on what is available where the ram can copy some of it's contents to free up space. The problem is even the fastest SSDs are many many times slower than ram. Android by default doesn't have swap, however it does use a low memory killer which essentially goes through and clears out apps that are in ram to free space. ZRam makes a compressed partition inside the ram itself which then acts as a swap partition. Basically when ram begins to fill up. It compresses data and sticks it in a sealed off area of the ram. This let's it stuff way more stuff into ram than normal. To enable ZRam I use fauxclock. Trickster for whatever reason does not work. In FauxClock go to memory settings, then set the Zram size to 300mb and click apply disk size. Then turn it on and set on boot. You have now essentially boosted the available ram via compression!
VM Settings:
There are numerous tweaks you can do to the VM. For this I use FauxClock but IK Kernel Aduitor can do this as well. In FauxClock navigate to memory manager. The first thing to tweak is an option called swappiness. This control is used to define how aggressive the kernel will swap memory pages. Higher values will increase agressiveness. I defaulted this to 10 however the default is 60. This will use more ram but give better performance. Next is VFS Cache Pressure. This controls the tendency of the kernel to reclaim the memory which is used for caching of directory and inode objects. The default used to be 200. Its now defaulted to 10 meaning more ram usage but more performance. Next up is dirty ratio and dirty background ratio. Some things pass through ram and stay there for a bit until they get flushed to the flash storage. These controls essentially dictate how long it should wait before flushing to the flash storage. The longer you can delay it the better performance and battery you achieve, at the cost of ram. Setting these higher will increase ram usage but increase performance. I recommend a background ratio of 30 and a dirty ratio of 50, however feel free to tweak them as you desire.
Color Control:
Next you may want to adjust Screen RGB, value, saturation, hue and contrast. WrinkleFree over in the Lean Kernel thread did extensive testing with a professional grade $1000 screen calibration tool. You can use this app http://downloads.codefi.re/savoca/kcal to control the screen.
For the most truly color accurate screen at D6500K:
Red - 248
Green - 246
Blue - 255
If you prefer a slightly cooler screen and the tuning the iPhone uses which is D7400K:
Red - 237
Green - 235
Blue - 255
More info can be found about color calibration here: http://forum.xda-developers.com/showpost.php?p=57265483&postcount=620
As for saturation. I like to turn it up a bit and make the colors pop a bit more so I leave it around 65. But quite honestly saturation,value,contrast,and hue are going to come down to tweaking it and finding what you like most. Have fun!
These settings are meant to be used as a starting point. Depending on your cpu binning and desires you will probably want to tweak these slightly to fit your needs. I'll add more as new features get added, I learn more, and I think of stuff to add Hope it helps someone!
Sweet! Good work man.

Are you trying to do this for a Benchmark?
Using the Faux app you can first set it to Intelliplug , then Performance (4) Cores and that should get you there.
If not, try setting it that way and reboot. I've noticed with this phone that I've had to reboot a lot for my changes to actually take correctly.
Cpu2 and cpu3 are stuck in performance...
And does anyone know where in sysfs to adjust mako hotplug?

Currently if you disable all hotplugs or if you use fauxclock to set it to usercontrol that enables Franco's mako hotplug. Thats why in an app such as faux you cannot easily force two cores online. However if you use Franco's updster app you can go to CPU manager then hotplug control and if you lower the load threshold it will hotplug more frequently. Setting this to 0 will force all cores online. Additionally as mistertac said. Using b intelliplug on either performance(4) mode or balanced(4) will use all 4 cores pretty frequently as well.
Introduction
This is a kernel for XT1572/XT1575 built from stock sources (marshmallow-6.0.0-release branch) with cherry picks from other kernels and some ports/mods done by me. It started as a personal build tailored to my preferences but just thought I'd share in case somebody might find it useful. My main goal is building the smoothest kernel I can get so performance is top priority.
This kernel is for stock ROM MPH24.49-18*
Disclaimer
Although I have experience with Linux kernels on desktops and servers this is my first Android kernel. I've been running this kernel on my XT1572 for a few days and seems pretty stable but that doesn't mean it's risk free. In fact I wouldn't dare to install it if you don't have a proper backup and some basic skills to deal with unexpected situations.

Donations
Although quite a deal of the important work has been done by the developers mentioned in the Credits section I spend many hours working on this. If you feel like helping me out I'd appreciate some tiny donations to cover some minor expenses.
Thanks to all of you who have donated, it's very much appreciated.
Profiles
One of the FAQ in most kernel related threads is "What are the best settings for .....?". This is the 10 million question since the usage pattern can be very different for each user. However, I understand less experienced users will appreciate some hints in this department, so that's why I'm posting some basic settings you can use as a starting point.
It's your job to further tune them to suit your needs. You should be able to modify these settings with whatever Kernel Control App you like the best, although not all settings are available in every app, in such a case tune those you can. The list is not complete (just the most importante settings) and is loosely based on Kernel Adiutor arrangement.
Please, keep in mind these are subjective values (based of personal preferences or popularity) and some people might like other settings for whatever reasons.

FAQ
I get random reboots, what is happening?
This kernel overclocks both clusters by default (a53: 1536MHz a57:2016MHz) and although this is very safe for most devices some CPUs are in the lowest spot of the binning spectrum and can't handle O/C very well. In such a case use a kernel control app (see the OP for references) to limit the maximum CPU frequencies, play with them until you find stable values for your device.
What are the best settings for battery life/performance/whatever?
That's hard to tell as every user is different. You can find some basic profiles in the OP you can use as a starting point. Notice the differences between then and build you own.
Why do some BIG cluster settings display N/A?
Why can't I change some settings on the BIG cluster?
If you get N/A or weird values when trying to change settings on BIG cores it means both are offline ("hotunplugged"). To work around this select "performance" governor, make your desired changes and then select you previous governor. You can also disable hotplug, make the changes, and enable hotplug again.
DoubleTap2Wake doesn't work sometimes. How can I get it to work all the time?
When device goes into suspend mode first tap is often missed (I suspect this is caused by Moto Sensor Hub). If you tap three times and get the timing right you'll probably make it work most of the time. As an alternative, Sweep2Wake works almost all the time
DT2W/S2W is acting weird or disabling itself
Make sure Moto Display is disabled. Open the Moto app, click on the stars in the top right corner, select Display and set to Off
Can I use this kernel in ROM X/Y/Z?
This is for stock ROM MPH24.49-18 only. It'll probably work on any stock based ROM but not guaranteed.
I use stock ROM but WiFi is not working
Due to some internal changes all modules had to be recompiled (WiFi included). In order to expose the new modules without modifying the system partition I had to implement a hack that requires root. Make sure you're properly rooted.
What's the deal with ZRAM?
ZRAM is a technique to increase memory available to the apps at the expense of CPU time. Memory space from apps not being used is compressed into a memory swap area and uncompressed on the fly whenever needed. As you can imagine this compress/uncompress process burns CPU cycles, potentially leading to worse battery life, lag and higher temperatures. Since this device comes with 3GB I can only think of one scenario where ZRAM can be beneficial: heavy multitaskers who care more about apps not reloading than battery life. For the rest of users enabling ZRAM doesn't make much sense in my opinion, and that's why it's disabled by default.
UPDATE: v0.10 includes an updated ZRAM driver that improves performance significantly. So much so that the benefits seem to outweigh the costs and it's been enabled by default.
What's the deal with KSM/UKSM?
Since many apps use the same libraries/resources it's very likely that at any given time there are multiple copies of the same data on different memory locations. KSM/UKSM tries to take advantage of that fact by scanning memory pages periodically and consolidating that multiple copies into a single shared copy. Much as like ZRAM it can have a good effect on heavy multitasking performance but at the expense of CPU cycles, and thus it's only recommended in the same scenario as ZRAM. Disabled by default
Ok, so do I enable ZRAM/KSM/both/neither?
I honestly think most users will be better off not using neither. If you feel like you need extra RAM I'd try KSM first, then ZRAM. Using both at the same time is overkill unless you are an ultra multitasker, in which case you should probably get a 4GB device anyway
How do I get WiFi on 6.0.1?
It's a modem version mismatch issue, you need to downgrade the modem. See this post.
Love to see more options! Thanks for sharing!!
Yeah this will be very good
Only One think that would be awesome try to implement the double tap to wake

As I said on the OP my main goal is performance/smoothness, so I haven't specifically sought better battery life. That being said I'm getting about the same battery life as stock with better performance, that works for me.
Nevertheless, I'm very interested on how it works for other configurations and usage patterns.
@dirtyhank could you please add hotplugging to the kernel? Preferably one that allows you to select how many cores to run as well as which ones, as in run the two A57s and turn off the four A53s. Currently I'm running two A53s at 1.2Ghz and the remaining four cores are always off.
The screenshot is from Lolipop, and it is the only reason why I havent upgraded to MM. Turning off cores definitely makes a difference on battery life.
Also, if possible, adding a lower speed to the min speed. Will gladly test anything you thow my way. Thanks in advance.
Is there any chance for a CM13 version and a DT2W fork from elementalx?

FAQ
Q: With which ROMs this Kernel is 100 % Compatible ?
A: Currently only with Android 9 custom ROMs, but Samsung stock ROM is recommended.
Q: Is this Kernel 100 % Safe ?
A: Yes.
Q: Will this Kernel Overheat the Phone if I use Highest Settings ?
A: No, you can't do anything wrong. Your phone has hard- and software overheat protection.
Q: How to Revert all Changes Made by this Kernel ?
A: Flash latest 3-parted stock ROM with ODIN or flash the Samsung kernel from my download site.
Q: How to bypass SafetyNet ?
A: Anable MagiskHide in Magisk app.
Q: How i can Tune this Kernel ??
A: Everytime you install or update this kernel you will face an red (demo) app "A2N Kernel Control..." open this app, and it'll redirect you to Google Play to get the full version (blue app).
Q: Can i use and Tune your Kernel with other Kernel Manager Apps ?
A: Yes, but you need first to unlock kernel with the A2N app full version.
Q: I've Installed the Full Version of the App, Will it Change any Kernel Settings by Default if i do not Change them ?
A: No, default app settings = default kernel settings.
Q: I've the Full Version of the A2N Kernel Control App, Do i still need the Demo Version of the App ?
A: Yes, there are some special features in-app-menu like "Fake Enforce" and debugging features for easy bug reports.
Q: How to Charge from 10 % to 100 % In just 1 h ?
A: E.g. set "AC Current Max" and "Maximum Charging Temperature" to the Max.
Q: How to get Max Speed for e.g. Highest FPS in Games ?
A: Set BIG / LITTLE CPU and GPU Freq to the Max, but avoid to use "unsafe" Freq's.
Then set CPU / GPU --> DVFS --> "Maximum Temperature" to the Max.
Now you can even cook an egg on your phone !
Q: Will my Custom A2N Settings Survive if i install Stock Kernel and then going back to A2N Kernel ?
A: Yes, as long as you don't uninstall it.
Q: Can i use your Kernel Control App with other Custom Kernels ?
A: No, it's not universal kernel manager app.
Q: My A2N App is Crashing after an Update, how to fix it ?
A: Re-install it. If it doesn't help, wipe dalvik-cache in recovery.
Q: My A2N App shows: "Please check your internet connection" - But i've good internet connection. - How to fix it ?
A: Settings --> network settings --> use private DNS server like "dns.adguard.com" - confirmed to work by user @Arnz09 - see his post here.
Otherwise send me a pm with the screenshot and you current location (city)
Q: Why I get lower benchmark scores with this kernel compared with the Samsung kernel ?
A: This kernel uses by default Max CPU/GPU DVFS Temp 65 °C to reduce the device heat. You can buy the full version of the A2N app to set the DVFS Temp up to 100 °C to get higher scores than on stock kernel.
Q: Why the Android Battery setting "fast charging" has no effect on this kernel ? - It charges always with around 1500 mA.
A: Because it would conflict with the built-in charger control.
The default charging current of approx. 1500 mA means no fast charging by default, even if you actually see "fast charging" in the notification section. This is also useful to reduce battery stress and device heat. To charge even with higher speed/current than on stock kernel you need to buy the full version of the A2N app.
Q: Why I've to pay money for just changing kernel settings ?
A: Well quality has its price. Also nobody forces you to use this kernel.
You can flash other custom kernels or flash the Samsung stock kernel from my download site. Good luck !
Q: When we get an update ?
A: This kernel is almost 100 % stable and works very well. Also this phone is now a bit "old" and therefore don't expect frequent updates.
Also don't ask for ETA's and if you do anyway, I'll ignore.
Q: How to fix audio stutering ?
A: Increase the PM-QOS-LIT / PM-QOS-BIG Freq in A2N app in debug menu --> "Audio" section.
Q: What is the benefit of editing the voltage table ?
A: to increase OC stability increase voltage and to decrease the device heat, decrease voltage. Last one will improve performance due to less throttling ! So it depends on your needs.
Q: How much is safe to undervolt ?
A: approx -50 mV is considered to be "safe".
Q: How to Report Bugs ?
- Please DO NOT report bugs if you are:
--- using "unsafe" Freqs
--- not using the latest release !
--- not using Samsung stock ROM (based stock ROMs are custom ROMs !)
A: Open the red A2N Kernel Control demo app and check in-app-menu (3 dots) then "Debug" and then on "logcat and dmesg" if you faced an app crash or if some features didn't work.
If the phone rebooted randomly, then tap on "last_kmsg". You will find the logs in your internal storage. After that you can attach them here in your bug report, by clicking "Attach files".

Play playstore app support only galaxy ace 2 ?
unfortunately something went wrong with the s8 app release.
need to contact Google later.
please be patient.
are u going to release a version for sm-g955f? your kernel sounds rly interesting would appreciate that.
thanks! maybe yes ... if many users want it.
G95/ g955/ f/ n？
For now it's only for G950F and only tested to work 100% stable with the CRGH Build.
Tested for very long time on my G950F.
Honestly i don't like to build software for a device i don't own .. and even not to mention to release Software without to test it on my own.
However if'll receive positive Feedback then i'll buy all S8 Variants in order to build a perfect Kernel for you Guys !
But for now lets start with this.
I'll test and update this Kernel on latest available Stock ROM...
So, stay tuned
Thank you very much, I will continue to pay attention to it. I am G955N.
I have s8+ g955f. I know that it is only for s8 but anyway, I tried to test the kernel, it is booting up but I have no touch screen. I would be more than happy to test any test build if you decide to make it for s8+ too in the future.
Στάλθηκε από το SM-G955F μου χρησιμοποιώντας Tapatalk
installed with rom deodex ambasadii deo mod v1.3 and it works perfectly, only with mtweaks I can not regulate much, especially the battery current, moreover, why is there only interactive and deadline scheduler? another interesting feature is the dex only with the cable, I have to buy it so I try it, great job, when the app comes out in the play store I try it better, now I want to test consumption.
@ace2nutzer could you send me the apk of the kernel controller in trial version on telegram, my nikname is @ pablonik79
I really cant wait to use it on s8+. Thx for your efforts #respectthedevs
G955f not available?
If the kernel I only for s8 variant it shouldn't be posted on cross device topic....I think?
But anyway, nice futures so it'll be nice to have a new alternative for both devices. There's not much development in s8/+ especially from kernel side.
Thx for your work

This Kernel is optimized to work best with the Stock ROM, but it's nice to hear that it works as well with custom ROM.
only with mtweaks I can not regulate much, especially the battery current,
Click to expand...
Click to collapse
Yeah that's normal it's a fully optimized custom Kernel, all features works only with the original Kernel Control App from me. Using such "Universal" Kernel Manager Apps can even make your Phone unstable and will not make things better. That's why i build for every Device // Kernel a separate Kernel Control App.
Otherwise i would build also an Universal Kernel App ... but it's not that efficient and this is what u Guys definitely don't want for sure.
moreover, why is there only interactive and deadline scheduler?
Click to expand...
Click to collapse
Because we only need one good working CPU Governor and I/O Scheduler ... right ?
Short and easy explanation:
Interactive: it's the perfect gov for low latency workloads. - So it's perfect for Android to have a smooth and quick response experience.
Deadline: It's optimized for Flash Devices, it's simple and stable - Also appropriate for Android.
All other Gov and I/O are unstable or will decrease the Performance and or battery lifetime ...
(at least not very appropriate for Android .... however there's also I/O sched "ROW" or "FIOPS" which would be also ok for android, but they are not that stable like "deadline" and the difference in I/O Performance isn't that much.
So i've removed them so that u Guys can't change (accidentally) this important Drivers.
when the app comes out in the play store I try it better, now I want to test consumption.

Behold the wall of features
Android Q kernel is based from Google sources Android-Q branch with applied on top of it Samsung's kernel sources.
Since there is no more ELS repository for Android Q kernels.. I made a branch on the same repository on Github called [ZeusELS] which is purely a completely stock kernel with linux upstreamed always to the latest :angel: that's if anyone wanted to develop a new kernel from scratch also.. ZeusELS is based from Google sources Android-Q branch with applied on top of it Samsung's kernel sources too ! :fingers-crossed:
Download links are always at the end of this post
ZeusROM Features for Android Q
[*] It is just simply a replicate of DevBaseROM from @_alexndr but with more debloats and Zeus Kernel ready inside... just flash it and it is ready
Kernel Features for Android Q
Imported N960FXXS4DTA5 kernel sources
Used updated ramdisk N960FXXS4DTA5
The kernel is now compiled with GCC 10.0.1 along with LTO [Link Time Optimization] using the latest updates available for [isl,mpc,mpfr,zlib,etc..] GCC is self compiled with all kind of flags optimizations applied for maximum performance benefits and increase code quality
Using GCC LTO with all fixes and optimizations which leads to faster kernel operations and less kernel code bloating which will lead to less kernel size in which allows me to make room and use O3 kernel optimizations which will increase kernel size a little bit for results in significantly improved hackbench performance, which is a sign that overall performance in the kernel is improved. It works especially well in conjunction with LTO.
Implemented/Using [W.B.T.] Write Back Throttling driver which increases IO performance and smoothness of the kernel operating generally.. what it does is...
[Enable throttling of buffered writeback to make it a lot
more smooth, and has way less impact on other system activity.
Background writeback should be, by definition, background
activity. The fact that we flush huge bundles of it at the time
means that it potentially has heavy impacts on foreground workloads,
which isn't ideal. We can't easily limit the sizes of writes that
we do, since that would impact file system layout in the presence
of delayed allocation. So just throttle back buffered writeback,
unless someone is waiting for it.]
Implemented hybrid poll mode With this hybrid scheme, we can achieve big latency reductions while still using the same (or less) amount of CPU.
Implemented various patches from 4.10/4.14/4.19 imported
Simple LMK! first in the history of Samsung smartphones with all updates and patches applied
Undervolted everything on the SOC from RAM,CPU,Camera,CPU Bus,etc..
Reduced SELinux expensive calls for audit and disabled entirely
Updated SchedUtil to the latest patches & updates
Updated SchedUtilX to the latest patches & updates
Implemented IOwait and Use it + Make IOwait boost more energy efficient
Re-adjusted Samsung values on nearly everything volts,battery,ram,etc..
Using the S10/N10 Values to our beloved Note9 for Exynos hotplugging drivers
Using CPU Assist driver and updated its values
Disabled all kind of Debuggings, loggings, tracings aggressively kernel size is under 30MB!
Boost DevFreq whenever a new frame kicks
Added PowerSuspend Driver which will help on battery saving extensively and integrated it to display driver
Using HTC's Fsync named [Asynchronous Fsync] and made it working as default for Note 9
Implemented Sched Yields to force sleep whenever it kicks in
Moved MMC driver to SCHED_FIFO thread to reduce the impact of
load on IO performance.
Applied O3 compiling flags to Crypto drivers for increase performance
Tuned Up ALMK [Adaptive LowMemoryKiller] values and use it by default
Adapted and Implemented Force Reclaim driver from Lenovo and use it by default
Killed Samsung's poor RBIN memory management
Implemented CMA from Qualcomms devices and Use it as a replacment of Samsung's RBIN here what does it do..
[CMA pages are designed to be used as fallback for movable allocations
and cannot be used for non-movable allocations. If CMA pages are
utilized poorly, non-movable allocations may end up getting starved if
all regular movable pages are allocated and the only pages left are
CMA. Always using CMA pages first creates unacceptable performance
problems. As a midway alternative, use CMA pages for certain
userspace allocations. The userspace pages can be migrated or dropped
quickly which giving decent utilization.]
Introduce and Implement and Use GCMA [Guaranteed Contiguous Memory Allocator] read below what it does..
[While demand for physically contiguous memory allocation is still alive, especially in embedded system, existing solutions are insufficient. The most adapted solution is reservation technique. Though it serves allocation well, it could severely degrade memory utilization. There are hardware solutions like Scatter/Gather DMA and IOMMU. However,
cost of these additional hardware is too excessive for low-end devices. CMA is a software solution of Linux that aims to
solve not only allocation but also memory utilization problem. However, in real environment, CMA could incur unpredictably slow latency and could often fail to allocate contiguous memory due to its complex design. We introduce a new solution for the above problem, GCMA (Guaranteed Contiguous Memory Allocator). It guarantees not only memory space efficiency but also fast latency and success by using reservation technique and letting only immediately discardable to use the area efficiently. It shows 15 to 130 times faster and more predictable allocation latency without system performance degradation compared to CMA.]
Implement binderfs for Andorid IPC
Wakelock Blocker is used by default and it already blocks the needed wakelocks by default
Added DropCache feature which will help with memory management on the long run
Tuned Adaptive LMK to work Asynchronously
Implemented ZRAM Deduplication feature which will..save amount of memory usage by zram. Read below the benefits...
[Android is one of the biggest users to use zram as swap and it's
really important to save amount of memory usage. There is a paper
that reports that duplication ratio of Android's memory content is
rather high. And, there is a similar work on zswap that also
reports that experiments has shown that around 10-15% of pages
stored in zswp are duplicates and deduplicate them provides some
benefits.]
Implemented ZSWAP same-filled pages handling feature look below what does it do..
[Zswap is a cache which compresses the pages that are being swapped out
and stores them into a dynamically allocated RAM-based memory pool. This patch adds a check to identify
same-filled page before compression of the page. If the page is a
same-filled page, set zswap_entry.length to zero, save the same-filled
value and skip the compression of the page and alloction of memory in
zpool. Improvemnt in preformance varies between 19% ~ 32% increased performance in store time & 49% ~ 85% increased performance in loading time]
Implement B-tree function and Made ZSWAP to Use it by default which will lead to the following IO bogo operations: * original: 73778.8 * btree: 393999
WireGuad using the latest version always
Added MoroSound!
Brought a collection of Paranoid Android & Xiaomi patches to our beloved Note9 devices
Tuned UFS net boost table
Speed up scatterlist to roughly a 2x performance gain & Speed up cache entry creation for mbcache2
Implemented some fucntions & drivers from 4.14 Kernel and use it on Note 9 [which have 4.9 Kernel]
Using Jump Lable on the kernel read below what does it do..
[This option enables a transparent branch optimization that makes certain almost-always-true or almost-always-false branch conditions even cheaper to execute within the kernel.
Certain performance-sensitive kernel code, such as trace points, scheduler functionality, networking code and KVM have such branches and include support for this optimization technique.
If it is detected that the compiler has support for "asm goto", the kernel will compile such branches with just a nop instruction. When the condition flag is toggled to true, the nop will be converted to a jump instruction to execute the conditional block of instructions.
This technique lowers overhead and stress on the branch prediction of the processor and generally makes the kernel faster.]
Using Jump Lable Relative References on the kernel read below what does it do..
[Reduce the size taken up by absolute references in jump label
entries themselves and the associated relocation records in the
.init segment, add support for emitting them as relative references
instead.This reduces the size of the __jump_table by 33%, and
gets rid of the RELA section entirely.]
Improve ION cache accounting
Added Fingerprint Boost Driver
Low Memroy Killer features... LMK Fast RUN, OOM Reaper, Process reclaim
Updated ZRAM & ZSWAP with LZ4,ZSTD,LZO compression algorithm
Implemented Devfreq Boost driver and updated it... look below what it does
"This driver boosts enumerated devfreq devices upon input, and allows for
boosting specific devfreq devices on other custom events. The boost
frequencies for this driver should be set so that frame drops are
near-zero at the boosted frequencies and power consumption is minimized
at said frequencies. The goal of this driver is to provide an interface
to achieve optimal device performance by requesting boosts on key
events, such as when a frame is ready to rendered to the display."
Introduced a centralized Energy Model (EM) management framework which aggregates the power values provided by drivers into a table for each performance domain in the system.

Applied PSI driver on RAM , CPU , IO Drivers... see what it does...
[When systems are overcommitted and resources become contended, it's hard to tell exactly the impact this has on workload productivity, or how close the system is to lockups and OOM kills. In particular, when machines work
multiple jobs concurrently, the impact of overcommit in terms of latency and throughput on the individual job can be enormous.
In order to maximize hardware utilization without sacrificing individual job health or risk complete machine lockups, this patch implements a way to quantify resource pressure in the system.]

Using always the latest GCC 10 Build with LTO self compiled
Optimized UKSM function and KSM along with it
Add ROW scheduling algorithm & ROW driver... mechanism of it is...
[The ROW scheduling algorithm will be used in mobile devices as default
block layer IO scheduling algorithm. ROW stands for "READ Over WRITE"
which is the main requests dispatch policy of this algorithm.
The ROW IO scheduler was developed with the mobile devices needs in
mind. In mobile devices we favor user experience upon everything else,
thus we want to give READ IO requests as much priority as possible.
The main idea of the ROW scheduling policy is:
If there are READ requests in pipe - dispatch them but don't starve
the WRITE requests too much.]

Using Galaxy S10 + Note 10 HMP extracted drivers combined and implemented it to our be loved Note 9!
Introduced [Host Performance Booster] HPB driver from Pixel 3! & Adapted it to our Note9!! Please read below what HPB can do...
[HPB is essentially caching of the NAND chip’s FTL (flash translation layer) L2P (logical to physical) mapping tables into the hosts (SoCs) main memory. This allows the host driver to look up the target L2P entry directly without betting on UFS’s limited SRAM to have a cache-hit, reducing latency and greatly increasing random read performance. The authors of the feature showcase an improvement of 59-67% in random I/O read performance due to the new feature. It’s worth to mention that traditional Android I/O benchmarks won’t be able to show this as as those tend to test read speeds with the files they’ve just created.]
(Source of this info ---> Here)
Added Ainur audio driver for those who want to use DTS Audio mods
Applied PSI driver on RAM , CPU , IO Drivers... see what it does...
[When systems are overcommitted and resources become contended, it's hard to tell exactly the impact this has on workload productivity, or how close the system is to lockups and OOM kills. In particular, when machines work
multiple jobs concurrently, the impact of overcommit in terms of latency and throughput on the individual job can be enormous.
In order to maximize hardware utilization without sacrificing individual job health or risk complete machine lockups, this patch implements a way to quantify resource pressure in the system.]

No Gravity Kernel 1.0.0 + 4.3 App Trailer
Hey, NoGravity Kernel dev coming from the good old OnePlus 2 here! I'm a graduating student in computer science and I actually work as a programmer. I made a pretty solid kernel for that old Oneplus device and even added Energy Aware Scheduling (EAS) support to it backporting new features like Dynamic Schedtune Boosting to this old 3.10 kernel. With it being pretty much at its apogee, I need a new challenge on a newer kernel (4.9+) while keeping NGK's mindset of Performance/smoothness while getting decent battery life due to added battery oriented features.
For those who want a to know more about my work here is the link to NoGravity Kernel for OnePlus 2.
The Kernel will boot using stock (Pocophone F1) CPU & GPU frequencies that correspond to the Balance Profile when Magisk is present. Overclocked frequencies can be selected in any kernel manager app. Other profiles for battery, performance and gaming can be switched to in my app.
To tweak the kernel easily, here's my No Gravity app! featuring custom profiles (Battery, Balanced, Performance and Gaming). My app offers some features that cant be found in other kernel tweaking apps. You can find them lower in the thread.)

This kernel should work on any ROM/Ports! Since I love OnePlus and I'm myself a OnePlus 2 user, I will do my best to fully support OOS ports.
Reported to work on: OnePlus 6 Holi Edition, OnePlus 7 OB8 & OB8 Quince, Quarantine Edition. OxygenOS devs do not support custom kernels so if you face any issues with NGK don't post in their groups, post here instead. Latest OOS may have calling issues as reported by some users.
-I recommend before coming to conclusion, give it at least 2 complete charge cycles and then raise any issue.
-I recommend to use my app, franco app or EX Kernel Manager if you need to tweak the kernel further
-CPUs since Snapdragon 845 can't be overclocked from kernel this is why it is removed
-Flash No_Gravity_Kernel-vX.X.zip file in TWRP (Latest TWRP Recovery Recommanded)
-(Optional) - Clear cache and Dalvik => if you do so, Use App Optimization button in NGK App.

Notes:
Max GPU frequency of 835MHz is only reachable manually as I don't consider it fully stable. On the other side, 820MHz Overclock is stable and is used in my profiles.
I wanted to use relatively longer dynamic schedtune boost duration compared to input boosts so made them separate in terms of length.
I would recommend turning off No Gravity app toast notifications from Magisk Manager app.

And many more under the hood changes...
Notes:
Thermal Suspend API : This is a small API I’ve written in the kernel directly (to make sure no background services are running for it) that unsets NGK thermals when screen turns off and enables them back when screen is turned back on. (This fixes some issues on some specific ROMs where screen wouldn’t turn on or phone would random reboot while device sleeps or is charging)
There is now a camera fix version to fix camera on ROMs with Q-Blobs like MIUI Q, so if your camera isn't working flash this one.
Kernel 1.1 Pie Edition:
NoGravity Kernel v1.1 now working on Pie ROMs
Using v1.0 Base
Notes:
This kernel uses v1.0 base so will work on both Android Pie and Q ROMs/Ports/MIUI
From now on releases will be separate in 2 builds: [9] and [10]. People on Android 10 should use [10] builds since it is rebased to Full Q CAF sources even tho [9] build would still work.

Picked port of RCU's taken from 4.14
Updated SDFAT to EXFAT
Removed a CPU boosting driver that could conflict with another
Battery oriented tweaks
Tried to fix random reboots and other issues some people were getting
Always upstreamed to latest! (4.9.206)
And many more under the hood changes...
Notes:
Profiles also have a QSTile for fast switching
If you didn’t already know it was only placebo/performance wouldn’t change, but don’t worry there are other ways to make performance better
If you want charging throttling, you can set it back on here by setting the value to N instead of Y: sys/modules//sys/module/smb_lib/parameters/skip_thermal
MIUI ROM/Port variants may have some issues but I didn't have much testers on those so please send logs if you have issues

Useful stuffs
Clean flashing a kernel:
1. Boot into recovery
2. Wipe dalvik/art cache, cache, system and vendor(if recovery have this option)
3. Reboot into recovery (only needed on some recoveries)
4. Flash latest ROM zip
(Optional) Flash other zips like GApps, DFE, etc depending on ROM and your preference
5. Flash latest Magisk zip
6. Reboot into system (yes boot with stock kernel first)
7. Reboot into recovery
8. Flash latest NGK Kernel zip
9. Reboot and enjoy
Not to be confused with a ROM clean flash!
Do not wipe data or internal storage!
Encryption fix
For the ones who uses an encrypted device, those steps needs to be done to worl properly with NGK:
To those who are facing screen flicker/bootloop upon flashing NGK on an encrypted device.
1. Dirty flash your current ROM and boot into system.
2. change your password to whatever you want then click on "No" when it shows "Secure Start-up".
3. Boot into recovery then flash NGK. You will notice that it will not ask for a password even though you are encrypted.
Taking logs
Screen Freezes:
-Connect phone to PC
-Run following commands in terminal:
[*]adb shell
[*]dmesg
Random Reboots:
-When the random reboot occurs press the TWRP button combo to got straight into TWRP
-Send the pstore folder as a .zip file located in /sys/fs/
Any runtime kernel/app related crashes that doesnt make the device reboot or freeze:
-Use Matlog app on play store
-Start recording before the issue
-Stop recording after the issue
-Send the .zip file created
Charging:
Okay lets break it down for yall.
Every kernel on every device has WARM_TEMP and HOT_TEMP values which are usually always 45 and 50 respectively.
When device reaches 40-42C charging rate will decrease more and more until it reaches about 45C where device will stop charging even if its plugged in for safety reasons. Battery must not charge when they are this hot.
Battery thermal removal: this will prevent throttling before battery reaches about WARM_TEMP. Once battery reaches about 45C there is nothing in the world you can do. So yea battery thermal removal is still safe, just a matter of preference because if charging throttles before reaching 45C it will heat less then continue charging but if charging doesnt throttle yea it will charge charge faster under 45C but may heat more so you may hit 45C faster. So as in every other tweaks it depends on user.
As per my tests I would get about those but that may vary for you:
Battery temp (°C) - Charging rate (mA) tuples
46-1800
45-1800
44-2000
43-2600
42-2800
What else? oh yea here are some tips for you to lower temps (cause yes some of you charge while playing pubg..)
Tips for lowering temps:
-Turn off NGK thermals from NGK APP
Right you all need to understand thermals first.. A lot of users are just asking best thermals, best this, best that.. there is no universal bests..
Thermals will throttle performance depending on heat generated.. so yes there is a gain in performance when using NGK thermals because performance will throttle at higher temperatures. Why do I say it depends? Well someone living in a hot place and is getting high temps and throttling will use NGK thermals so he gets more performance for the same temperature point but there is always throttling else a phone would heat too much in the end and be really unsecure and all. That being said, if your device throttle with stock thermals then you go ngk thermals it will throttle at higher temps but in the end may still throttle and if you hit too high temps it will throttle even harder to keep temps low. For those people using normal thermals would be best since yea performance will throttle but it will prevent the phone from getting higher temps which could lead to more intense throttling. (Can also read about charging above you may want more aggressive thermals that will throttling performance to reduce heat so you can charge phone)
So next tip:
-Reduce Big cluster max frequency as this cluster is a hest generator
-Use another profile than Gaming! (Performance for me is best because its less aggressive, some people prefer balance for gaming)
All in all, try stuffs by yourself I think I did my part guiding you through all this, the best things you can do is the best things for yourself not necessarily the best for others.
Touchscreen Tests (NGK v1.5.5):
Spent a whole week with testers to just sit down and find the firmware to choose and then rebuild the drivers from the groud up.. but first here's an intro
Intro:
Small intro for everyone cause many people confuse many things..
-Panels: We have 3 main panels:
FTS, NVT REV1 & NVT REV2
-Touch firmware: comes in kernel and also in ROMs but kernel will flash its inbuilt firmware if the kernel firmware checksum is different to the one already present in ROM
-Touch Drivers: comes in kernel and those dont have numbers/versions its up to the kernel dev to make changes it those so stop asking for driver version no one can answer that precisely compared to firmware
Tests:
Alright now enough talking, the tests and results.
-Panels:
For FTS panels, using stock xiaomi drivers was fine no touch issues seem to happen since those went out.
For NVT panels, some had touch issues on rev1 and rev2 depending on firmware used while keeping xiaomi stock drivers so below tests were focusing on NVT mostly
-Firmware:
We tried 3 firmware and the ones who remained are 9.1.24 and 10.3.7 since other one gave issues
So I did incremental test builds modifying drivers for both firmware
-Drivers:
For drivers, as said before I reverted all changes to xiaomi stock drivers from their source. Some issues were present for some on both firmware version and different issues on both panel revisions (rev1 and rev2)
-Latency:
some issues was only related to latency and I knew latency was going to be better by optimizing the drivers later on
-Touch issues:
So based on that, I only took account of the issues present between firmware for each driver changes
Part 1:
Part 1 was updating novatech drivers from a CAF source that can be seen in my kernel source. So did that, compiled 2 versions again fixed some small issues here and there like firmware flashing wasnt working, touch didn't work at first and some bootup issues, anyway main thing is that novatech driver were updated a bit with less variable locking and such coding changes making the driver faster. Results after that were good it fixed some people's issues but latency wasnt perfect.
-Part2:
Now was time to optimize the drivers and did for both NVT and FTS (most of those optimizations were seen in previous ngk versions) but needed to add them again and add some more and see how they impact (cause not every optimizations means better results, some optimizations introduced issues)
Conclusion:
So in the end if TLDR
The conclusion was that issues were fixed after some driver changes as some optimizations made them worst, 9.1.24 firmware gave better touch (mostly under load or heat a.k.a for gamers) and didnt impact day to day users hence why NGK uses now 9.1.24 drivers.
BUT that is based on the fact that I reviewed the drivers from official xiaomi source, then updating them, then doing specific optimizations, other kernels may have different results or different ways of doing tests, thats just how I did it.
So yea for people who wont like touch, I will send this cause I did work on it to give better touch to most users and limiting the touch issues. I still dont think its possible to have perfect latency and perfect touch due to our phone but here's what has been done..
Great work as always, glad to see you here! NGK was one of the best kernels for OnePlus 2, I'm excited to see what NGK brings in for Poco. You deserve much more appreciation for your work, I am doing my bit. For whosoever appreciates his work, following is a crowdfunding link that we created for getting Pierre a Pocophone, as he does not own one. Just to be clear, he isn't involved with this anyway, we, the OnePlus 2 family has done this on our own will, as a token of appreciation of all the work he has done for the community.

Havent been tested on Oxygen OS port yet.. Let me know how it goes! I'm not really into screen overclocking unless you want your screen to be damaged in a year... :cyclops:
Nice Work
Will Post it in Poco Official Channel:highfive:
Thanks for the effort! Although it's weird that almost every kernel devs are saying that CPU OC is not possible/necessary in recent SoCs anymore.
Will the source code be available? Can you create a script to easily run the build process for the kernel so that we can mess around with it?
Congratulations bro
Flashed the kernel, but the no gravity app doesn't detect the kernel.
Edit- My bad, it says coming soon in OP.
Legend is now working on poco. So lucky to have you bro.
quick question, if i have drunk optimus installed, how do i change it to this kernel?
and how to update it?
thanks!
Awesome bro... keep it up..
