For STOCK
Hello every one, just sharing my kernel for the H990 so other people can also use it as well as it helps in finding out bugs and issues.
Now, I'm not really a super dev like franco or myfluxi or showp1998 or those other great guys , I'm just some guy who likes to have his device do what he wants and puts what he wants on his device as well as it being some sort of a hobby. came from the galaxy s3 T-mobile, & Xperia M which I've also compiled my kernels on and now here on the LG V20
I am a fan of KISS (keep it simple stupid) but i also want advanced features hence the PARADOX,
this kernel was forked from DOTS which is LGE V10G sources
FEATURES
Compiled with Linaro 7.2 toolchain
Upstreamed (as of posting Linux 3.18.102)
GPU OC - 652mhz, no CPU OC
AUTO SMP Hotplugging
Interactive governor (though it might change in the future) other governors removed
ROW io sched, other ioscheds removedAdreno idler
Adreno Boost
KCAL support
UKSM
CRC on/off (your choice if you want it switched off, allegedely gives a 30% boost)
FSYNC on/off (again your choice if you want it enabled or disabled for performance boost)
Dynamic Fsync ( if you want fsync operations to happen only when screen is off)
powersuspend driver
DriveDroid CD-ROM emulation (use your phone as a Windows10 or any OS for that matter as an INSTALLER)
Westwood as default TCP algorithim
boeflla wakelock blocker (use my version of kernel adiutor to access its settings)
Optimizartions here and there
more to be added soon
KERNEL MANAGEMENT APP IN SECOND POST
DISCLAIMER
I am not responsible for any damage what-so-ever done to your phone, as with any kernel, you accept this risk.
Known BUGS
using PPTP vpn's cause a kernel panic,
light bleeds from the 2nd screen to the main screen due to diffrences in brightness when using Backlight Dimmer
but still not bright enough to burn your eyes when you turn your phone on in your pitch black room

INSTRUCTIONS/HOW TO
same as DOTS for 1st time rooting
Follow the instructions provided by emdroidle here : https://forum.xda-developers.com/v20...-h990-t3624296
At step 16, instead of typing fastboot reboot, just unplug the usb cable, remove battery, wait 5 sec, put the battery back and reboot the phone. This should limit the risk of static screen at reboot.
Once the kernel installed, update your phone to the latest KDZ for your region using KDZ Writer : https://forum.xda-developers.com/v20...riter-t3649818
1st TIME INSTALLING
PLEASE DELETE texfat.ko in /system/lib/modules folder using your root file manager of choice
or run
Code:
[STRIKE]rm /system/lib/modules/texfat.ko[/STRIKE]
after flashing in recovery
For those rooted with custom recovery just flash in TWRP

Yes you can
Hey, nice work! Glad to see some more action.
I am on rev 1, everything runs very smooth. So far only one comment: auto rotation doesn't really work. Can you also test it?
Waiting for updates and thumbs up for the dev!

I'm just glad im getting some feedback, weird auto rotation works fine for me and was not experienced by 2 other people who tested the kernel, whats your model? rev-2 is up btw,
Flashed Rev-2 a couple of hours ago.
All good so far. Will update after a day.
Thank you dev
Hello everyone, just wondering if this kernel is compatible with H990DS ( dual sim card ). Thanks in advance.

Thanks bud!!!!!
Tested rev 2 for 2 days and the phone is a bit warm, drains battery faster and not as responsive as rev 1 so I switch back to it waiting for rev 3. Anyway rev 1 works better for me than original Dots
Thanks buddy!
Just dirty flash from DOTS 1.4 to rev 2 for the backlight dimmer.
Thanks bro:highfive:
Rev 3 is out guys,
changelog

Added an app to control kernel features in second post
its still the same as kernel adiutor app plus an interface to control boeffla wakelock blocker and a different name and icon
Started using rev3 since you posted it, coming form DOTS 1.4 on H990DS. Seems to be behaving a little better, running cool and having a bit better battery life (though some of this might be due to the post_boot.sh mod that's posted on this forum that I installed alongside your kernel). 0 issues encountered, auto rotation works fine.
*when i set backlight dimmer in my screen the edge of top right side lighter than other area.

Yes its described in the bugs on 1st post, its gonna take a while to fix as my classes have resumed, but i will try and fix it in the future
Hi guys, im getting a hard time trying to make sixaxis app work, since the kernel loads bluetooth modules separatelly Im wondering if anyone can try sixaxis compatibility checker with this kernel.
Tried with dots and mk2000 with no luck. Weird sixaxis app works fine with other v20 like h910, h918 but on h990ds is a no go.
Sixaxis compatibility checker is free on the google store.
Thanks!

Supports GPU Overclocking or Undervolting (Thanks to AndreiLux)
pegasusq CPU Governor pegasusq set as default (obviously)
Filesystem Features (Currently Supported)
ExFat (Using Proprietary Samsung Modules) *Stock based RedPill only
Fat32
Ext2/3/4
CIFS (cifs.ko is in /lib/modules)
Ext2Int for N7100 (Thanks to mattiadj for idea and base script that I used to get it fully working on N7100 and RedPill) (ExFAT and FAT32 only) *Stock based RedPill only
I/O Schedulers
SIO (2012 0.2 version) (tweaked for Flash) Set as Default
deadline (tweaked for Flash)
zen (Thanks to bbedward)
noop
row (Thanks to Tanya Brokhman)
Tweaked values in deadline and SIO I/O scheduler to give better than average throughput while attemting to improve latency (if not more aggressive). Based on our initial (indicative, not conclusive... yet) testing, having these in line with the vm dirty, expire, writeback values + ext4 mount options to "schedule" write outs as fast as the system can handle it works quite well to balance throughput with latency expected in a mobile device. We took the big picture view and tested our tweaks instead of copy pasting random "known" good values and challenged some assumptions even we had at the start. The result is a mobile device tuned for average throughput and balanced battery life with good latency (not the lowest latency out there, but given the benefits of better I/O throughput and potential battery savings + extending the lifetime of NAND Based storage I think it was a compromise worth taking) I could have tweaked it for extremely great throughput and battery savings but that wouldn't be fun to use. I hate micro-lags myself.
Our Test Data regarding I/O schedulers and Kernel Tweaks can be found HERE.
The blog post that describes what we are trying to do can be found on my blog post HERE. (Thanks to s2d4)
Memory Features
Custom minfree values tweaked for 2GB RAM
Tweaked vm values in sysctl that's optimized for latency

Performance Patches Enabled
Mike Galbraith's Ultimate CFS Performance Patch (CFS Autogroup)
*More info on this here: https://lkml.org/lkml/2010/11/20/91
Added the CGroup Patch:*Added [PATCH] cgroup: Provides a way of tasks grouping by timer slack value
by Kirill A. Shutemov Based on patch by Jacob Pan. Introduces per cgroup timer slack value
which will override the default timer slack value once a task is attached to a cgroup. It's useful in mobile devices where
certain background apps are attached to a cgroup and minimum wakeups are desired.
Experimental Latency Related Patches
Disabled "fsync disabled" by default
(can be enabled by doing an echo "0" > /sys/class/misc/fsynccontrol/fsync_enabled
in a terminal emulator or as a script for gscript or scriptmanager) (Or use STweaks to toggle it) (Thanks to Ezekeel)
Using the tweaked Ext4 filesystem + scheduler and mount options leaning towards latency + vm values in the kernel
makes the most of the speed of Flash Storage based devices. At the speed at which the data is written to and from the kernel
to the Fast Storage devices, you would only lose up to 1 second worth of data at most IF the kernel crashes.
I don't plan on that happening so I enabled the system to get the maximum possible performance in this area.
Tweaked Ext4 Filesystem (Patches + Mount Options + Tweaked IO Schedulers leaning towards latency)
Tweaked the mount options for Ext4 to adapt to the current focus on latency

All the hardworking Kernel Devs at lkml.org
(Linus Torvalds, Jens Axboe, Mike Galbraith, etc.)
Special Mention to the following:
To my mates at the HyperDroid Dev Team: (who help me test and refine the features of our kernel for our ROM)
D.O.C. (formerly doctorcete) (for the friendship and being an example of diplomacy in
dealing with usual ****storm of questions from users who refuse to search and read)
kristofpetho (for his excellent work on the HyperNote and his patience with dealing with bugs that destroy the user experience)
Arighi (for the initial guidance on how to get the kernel booting and working & a lot of battery driven patches)
AF974 (for the Overcome based Recovery on S2 that's so bad ass I want to stay in recovery all the time.)
petsasj (for his great work on HyperDroidParts for S2 and all future Apps that are just pure awesomesauce!)
sicopat (for letting us use his server and helping us out with a lot of things smali)
s2d4 | phly-phantom | amerikian (for testing everything at the risk of the potentially time sucking Soft Brick...)
Disclaimer: I made this for my personal use and has been personally tested by me and my team (HyperDroid Dev Team).
While it may work for other N7100 International ROM's, we have not tested it personally.
You have the liberty to choose to use this Kernel and by flashing this Kernel you will have
surrendered your right to complain that you lost your Warranty. If you're smart enough to figure
out WHY you need a Custom Kernel, you SHOULD be smart enough to undo it if you need your
device serviced officially. If your device explodes, melts or otherwise disintegrates from its awesomeness
I shall NOT be held responsible.
Reposting the Kernel: Please don't repost this kernel anywhere else.
Keep the download links intact as I have taken the effort to provide fast links for everyone.
If you can't understand English well enough and feel the need to re-post this kernel on
a foreign language web site or forum, please let me know first and link to this page...

Naming convention:
x.y.z
"x and y" means they are stable releases tested by peers worldwide and have proven to be good enough to be a daily driver.
"z" is added to connote its an unstable release that is currenty being tested for new features introduced. Not for the faint hearted.
e.g. 0.2 is a stable release; 0.2.1 is an unstable test release
features in 0.2.1 that make the cut will make it 0.3 or the next stable release and so on...

FAAAQ's
Kernel Frequently Asked & Answered Questions (FAAAQ)
What exactly IS the RedPill?
The RedPill is a custom kernel for the Galaxy Note 2 (N7100) International version. It's aptly named to provide users a choice. This is how I would have built Samsung's stock kernel. So, I used the Samsung Source from their site as a base and added relevant patches that are built on the shoulders of giants... such as arighi, gokhanmoral, Entropy512, AndreiLux, codeworx, netarchy, hacre, franciscofranco, Ezekeel, imoseyon, Erasmux, cattleprod, hardcore, faux123, etc. and all the kernel hackers of the world that work on making this usable for all of us... I claim nothing to be original or created by myself... I simply put together features others have created that I personally would like to see and use in my own device and share it with the world because I can AND choose to do so... While I do bugfix the occasional compile error and test for near perfection, it's nothing compared to those who write most of the code for the Linux kernel. Major props to all of them!
Where is the source for building this Kernel?
You can find the source HERE. I love GPL and We should all support Open Source Software and its Developers. Please Note that Open Source doesn't mean all of this magically wrote and patched itself... it takes a lot of FREE time to do this and would appreciate if you let us know how you've improved the code.If you know what you're doing, you can easily build your own kernel too. *Please let me know if you have any improvements you feel should be included and send me a pull request. *If it tests okay, it may be included in the next release.
FYI, I'm not particularly fond of devs who release their source as tarballs. (I'm looking at 'ya Samsung!) I'm pretty sure you use a tool like git internally to manage all the changes and revisions. Why do you have to make it so hard for those that want to play with the source by releasing it in a tarball instead of publishing it on github or bitbucket? If you're a kernel dev that does this I consider you "open-forced" NOT "open source". If you don't want to use git and can't be bothered with it why not make a patch and upload that instead?
Does the RedPill support ROMs for N7105 and other N7100 variants?
As of the current Revision Released, I will not be working to making it work on a device I don't currently own. I only build kernels I can actually test myself. While "building blind" might work, I prefer to break my own device before someone else's as they probably paid good money and worked hard/smart to be able to afford the device. FYI, I'm also not in favor of devs who build blindly then ask for donations so they can support the device. I want to own my device, not let it be owned by those who donated their hard earned money to get you the device. I've seen too many "devs" build blindly then ask for a donation so they can support the device, only to find a newer, better and faster device comes out and then chooses to buy that instead of the device he built blindly for and actually got donations to buy it. Talk about Bait and Switch!
Why doesn’t the RedPill have high benchmarks?*
That’s done on purpose to keep YOU away. Seriously. The way the VM system is tweaked (dirty ratio’s, minfree values, etc.) + the focus on better latency in any type of load + a lot of other small tweaks all lead to good performance and battery drain in actual use (I like using my device and not keep it sleeping to bloat my battery stats, thank you). This may not give you the benchmark scores you want to be able to show off… which is good since it means YOU stay away from this kernel and continue to rely on benchmarks rather than actual usage.
Why should I even ROOT my device? Is a custom kernel more secure?
With the Exynos-Abuse Exploit out for ANYONE to use, you're probably better off rooting and installing a custom kernel that includes the fix of AndreiLux. (RedPill and Perseus as of this writing) Now I know it will void the warranty, as you all are aware of, but if the only way to secure your device and your personal data (You don't want anyone to see your google search terms and results as well as those "private" moments that you may have kept for yourself just like any normal person) is to root and install a secured kernel, what choice is Samsung giving you?
Can you imagine what a nefarious and talented malware developer could do with this? They could break your system and have a pop-up that says "Pay up to free your system from being one of my mobile drones"... OR "Donate to get the full features of your device" (This one actually happens a lot on XDA... some talented dev gives you partial features to lure you in... then WHAM, BAM, THANK YOU MA'AM... If you want the full features, please donate yada yada yada...) I digress, as always.
Now, would you rather wait till Samsung officially patches this exploit and run the risk of exposing yourself to the risks this exploit opens you up to? Don't assume malware devs aren't rushing their current code to try and pry their way into your system using this exploit. For all we know, they're busy trying to cover up a similar exploit and currently awaiting Play Store approval. Yes, even the Play Store Apps can compromise your system. Even if Samsung does act fast, (not as fast as AndreiLux since he fixed it in a jiffy) how sure are you that your system hasn't been compromised? You wouldn't even know it.
The best reason to root RIGHT NOW is to completely secure your system, now more than ever. If you need to claim a warranty, you can tell them:
a. I had no choice, you messed up, xda-devs cleaned it up.
b. Flash back stock kernel and remove any trace of root and your use of a custom binary.
c. Completely brick your phone and tell Samsung that the exynos-mem exploit was actually used by malware that zapped your system dead.
I'm not a fan of any of these choices since I believe warranties should be honored by the manufacturer, especially if the bug they created was the reason for the claim for warranty in the first place.
How do I know I'm secured from the Exynos-Abuse Exploit?
Don't rely on apps that tell you whether you're vulnerable or not as the low level kernel fix AndreiLux implemented doesn't need to change the permissions of the /dev/exynos-mem.
Try running Chainfires Exploit APK and try getting the exploit to say anything else but "FAILED"... or head over to the thread HERE and download the exynos-abuse binary and run it from a terminal.
$./exynos-abuse

Click to collapse
If your shell changes from $ to # then the exploit was successful, if not then you're safe.
Can the RedPill be OC'd and UV'd?
It can be UV'd and OC'd.By default, I've decided to keep all voltages and clock speeds stock as experience has taught me that NOT ALL DEVICES ARE CREATED EQUAL. You can UV the CPU arm voltages and OC using 3rd party Apps that do that. (SetCPU, VoltageControl)
Can the RedPill GPU be OC'd and UV'd?
Yes. Thanks to AndreiLux. You'll need to use STweaks to fully configure this. YMMV as always.
Why a tweaked deadline and SIO I/O scheduler?
The deadline I/O scheduler by Jens Axboe has proven itself as a low overhead, high throughput and acceptable latency I/O scheduler. *When tweaked for NAND based Mobile devices, it does even better. *While it "starves" writes by default with a 2:1 Read:Write ratio, this can easily be tuned via sysfs.
Why is my favorite governor (whichever it is) not available?
Simplicity is the Ultimate Sophistication, as Leonardo Da Vinci eloquently said. *Based on extensive testing and user feedback, we gathered that these 2 governors included gave the best performance and battery life on our device. Simple choice to have only the best ones available based on actual testing and feedback. *I included only these governors so you all have a simple choice to make in finding your favorite one. *These are all tunable via sysfs so you can skew it towards battery or performance based on what is important for you. *Don't expect uber smoothness and 16 hours screen-on time though... *there will be compromises when leaning towards any of the two factors most users consider important in a kernel.
Why LZO Compression for the Kernel?
It decompresses much faster than any other, bar none. Since the kernel size and compression speed is not an issue when using LZO in the kernel. (You only decompress the zImage when booting. Compression is done when building the kernel) Don't believe me, believe the data right HERE.
Why ARM Topology and sched_mc?*(From linaro.org)
"The sched_mc function adds a power saving awareness to the Linux scheduler which is tuned for performance by default. When sched_mc is enabled, the scheduler tries to gather the running processes in a minimal number of cpus and clusters. This choice of the location of a process is done thanks to the cpu topology function which describes the affinity between cpus."
(more info HERE)
Why is my AndroidOS usage so high?
This is most likely a reporting error from Android itself. Use Better Battery Stats to closely watch what really eats your battery. That has shown to be more reliable. (If I were Android, I'd fold buy out BBS and fold its code in by default) If you still have doubts, do a real world battery test, as some have done, and they saw that their battery consumption actually remained the same or in some cases even improved. YMMV, of course. Let's not fall for "placebos" here and say that "hmmmm.... since AndroidOS must be high than my battery doesn't last as long!"
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Ultimate Version FAAAQ DEPRECATED SINCE MOST FEATURES ARE FOUND ON STABLE
Why SLQB? (According to its author, Nick Piggin)* (Only for the Ultimate Revision)
”SLQB is a slab allocator that focuses on per-CPU scaling, and good performance with order-0 allocations. Fastpaths emphasis is placed on local allocaiton and freeing, but with a secondary goal of good remote freeing (freeing on another CPU from that which allocated).” Using this on the Stable version breaks ExFat from working properly. Thus, the Ultimate version is for those who don't need ExFat support.
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
HyperDroidDevs FAAAQ
Where do I report Issues or Get Community Support?
Use this thread to report issues, preferably with a last_kmsg, dmesg in a text file or a logcat. How do you do those? I'll let you use XDA's brilliant search function. And no, it's not broken, the search function that is. (I've heard that so many times... "Search isn't working so I posted a question here instead...")
Where are the HyperDroidDevs and their Team from?
We are an international team of crazy people who all have real life day jobs that are mostly not related in any way to Android Development. We're crazy enough to spend sleepless nights trying to make our devices (which we all personally own and have NOT been donated) better than how we received it. We come from all over. I am from the Philippines, where it's always FUN to be! We have Devs and Team members from Spain, Greece, France, Finland, Germany, Italy, Netherlands, Canada, USA, India, Poland, Philippines and even more countries.
How do I show my appreciation? Can I donate to you?
You can show your appreciation concretely in several ways:
Pressing the "Thanks" Button on XDA
Follow me on Twitter @sarcastillo and "Like" our Facebook Page
Report issues politely and completely
Donating any amount is completely up to you. *I look at donations as a "tip" for a job well done, rather than a "wage" or a "bounty" to get things done. *And Tipping is always up to you... the tipper. *I won't stop development if you don't donate, that's for sure, as I do this mainly for myself and my HyperDroid mates to begin with. I make more money running my own business than this hobby so “tips” are not a necessity… it just tells me how many people actually find the work useful enough to say thank you via a financial gesture.
This Kernel will ALWAYS be FREE to Download and USE, even if the time spent making it IS NOT FREE. *That's Open Source. (The time people spend on open source projects could have been used to spend more time with their families, for example. But the Devs commitment to get something done right is almost always tugging at him to Dev just a little bit more) *
*I've personally donated to Devs who've done things I would never have been able to figure out at the time they did figure stuff out. *Learning anything new takes time and time, in my book, is more important than money as I can't turn back time, while I can always earn money. SO I donate to Devs who spend their free time making Stuff better and easier for those of us who haven't figured out how to get it done.

Please see my response in Post#18
I would never open Off-Topic threads anywhere. On any forum.
Ladies and Gentlemen,
It gives me great pleasure to introduce to you an unofficial port of the Z1
Pimped Kernel
This is a kernel for CM11 based ROMs and uses -caf. If your ROM isn't faily new and doesn't use -caf then don't expect this kernel to boot. It was built inside Carbon and I have tested in there, it should boot CM/FXF, SlimKat, LiquidSmooth, Carbon, Omni, etc. I don't know how well it will boot PA/PAC/etc that are further away from this codebase but you are welcome to try. As this is a first build so expect some FCs and reboots, and and not all features will work. Please read the OP to see what is on offer. Things that won't work are LCD/Touchscreen/DT2W, and others may be prone to bugs.
This has kernel is built with Linaro SaberMod Toolchain 4.7 and -O2 etc optimisations (not as many as the slimkat kernel). Performance seems good, and the ability to underclock/volt and turn off cores should give extra battery life.
Please don't use this unless you know how to get out of trouble/bootloops/non-boot/lost recovery/etc. I nor Androguide.fr take any responsibility for dead or undead Z-Ultras
Kernel features are controllable through Androguide.fr's Pimp My Z1 app, (thread here).

DT2W/S2W/etc all use a different touch-screen driver than we use on the ZU

When I open camera directly after boot it works fine ,
when not I have also FC
Im using camera kk app and it works fine. Just first time camera is not moving (it stops on first "seen" frame), but it is on every kernel (maybe rom's, maybe app's bug) and after killing it in recent apps and starting again everything works fine
Strange for me is that this kernel has more governors etc, and i always thought that coz it we should have less ram, and there is more than ie unofficial slimkat kernel
Edot: Is there any chance for f2fs version in the future? Its a lot better than ext4, so it can make our ZUs fly even better than now

after a bit of flashing and testing the no outgoing calls is a bug in the test build of Carbon not this kernel so all is good on this front.
This kernel boots the last couple of Carbon builds, back to at least the 19/4 so that's another plus.
I'd not really had the camera issue that many people had had in the last few weeks on the CM based ROMs so it's sort of new for me.
You made it!!! Congrats and THANKS! Perhaps it's time I go back to a non-stock ROM now, just to try this kernel...
I found other problem (at least for me) with pimp my z1. I cant set 2nd core governor, coz it always return to intelliactive last saved? (im not sure as sometimes it stays on last saved sometimes on earlier), now, as i know how it works, its not the problem to set governor I want, but its strange bug. I would use trickster but there I cant set different governors for every core (As i found out set governor is only for first core)
EDIT: Maybe someone answers: What is Pen Mode in this app? If it is what I think we dont need it as our phone support mostly everything as a pen. The same for gloves i think
Has anyone tried this Kernel on CM11, if so any problems?

Next few things:
-
1. After reboot very often CPU governors are changed.
2. Additionaly to setting governors: They are setting itself. Before I set nightmare/nightmare/powersave/powersave and after going back to menu and againd CPU Control it was nightmare/<last saved?>/powersave/powersave. Now after reboot it was nightmare/nightmare/nightmare/nightmare (with per-core on) and after menu->CPU Control nightmare/intelliactive/powersave/powersave (intelliactive wasnt last saved or anything)
3. Sometimes after reboot Pimp my Z1 returns GPU settings to default ones
4. Power Managments, I/O tweaks, Memory managments too - Misc on the other hand are always remembered correctly
Yes I have "set on boot" on. Strage coz mostly (4/6 for now) everything is remembered correctly ie now after next "test" reboot

I'm wonder if it is more the app than the kernel?
I have managed to peg the first core at fill tilt once and another time to have all 4 core online all the time. The second issue can be solved by turning all the options off in Power Management, it's a known race condition by the looks.
~5% battery drain over night, but it looks like google services are causing wakelocks again on my ZU
Its hard to say coz there is bo more apps which can let to use most od options kernel has (ie trickstermod let set governor for all, i/o too for both memories). But i would think its app+phone compatibilty issue not kernel, but not sure about it

After first night it was worse for me - 13%. It coukd be coz kernel was just flashed ot coz my set up, but its too much
But this second core governor annoying.me too. I found out that if i set it few times it stay till sometime after reboot (just after reboot and getting su rights, governors are right(. Anyone has similar problem? Can moving app to system/app helps?

Hey guys,
Here is my second kernel project for you all to try. I did my first kernel project on the Google Pixel/XL.
Some may know me from my ghostpepper\butterfly Interactive governor Tweaks from the HTC 10. And later also the widely used Pnp Mod.
I hope to achieve great performance while maintaining stability with this kernel.
I did a few performance tweaks and audio tweaks.
Features are:
Included blu_active CPU governor (you have to rename system/etc/pnp.xml to system/etc/pnp.xml.bak and reboot in order to use blu_active)
Enabled MAPLE, SIO, SIOPLUS, FIOPS, ZEN, TRIPNDROID, FIFO and DEADLINE IO scheduler
Enabled advanced TCP Congestion Control
Included GPU Boost
S2S across navbar area
KCAL color calibration
Button Mapper Support
Fsync On/Off support
Green Pulsating Notification LED
Fingerprint Double Tap to sleep support
Interface to boost memory bandwith upon turning on the screen to achieve faster wake up time
Slimbus Enhancement may improve audio quality
Button Light Notification from @tbalden
IO Sched Switcher
Interface to boost UFS Storage Controller
Power Efficient Workqueues
Adreno Idler
Fast Charging
Reworked GPU Section
Before flashing don´t forget to backup your Boot partition in TWRP.

Thank you for the nice welcoming
Next release will have some upstream commits
Also you all are welcome to give some feedback.
nice to see that development is kicking up this weekend
Best kernel on Pixel XL nice to see you here. Good luck with everything :good:
So it seems that CPU OC isn’t working quite well with my chip. Tried yesterday 2,5 ghz for the big cluster and it didn’t even make it through boot process.
New release will be this evening.
Please report back how the kernel works for you.
Also please state the model you are on. But it should work for dual and single sim I guess.

Update to 0.2
Hey guys and girls,
here is the update to 0.2
includes all previous features
Changelog:
- patches to loadavg
- Upstream: reimplement mb2cache
- mm: slub: Default slub_max_order to 0
The kernel runs really nice for me.
Download: https://www.androidfilehost.com/?fid=889764386195910663
Have fun with it and a nice day
P.S.: Next release will have some surprises. But I want to make sure it is stable.
Thanks for your work, i will give this a try
So how is everyones experience?
new kernel release will be soon :victory:
Update to 0.2_2
Hey guys and girls,
the promised update is here. It may not seem like much but I managed to put a few new things in the kernel.
I had a play with different IO schedulers. As you may have noticed the new storage of our device is already blazing fast but I tried to make it even faster.
So I managed to built in the maple Io scheduler from @frap129. It results in slightly better IO speeds than stock in my tests. But this is only the first part of the IO journey.
Next release will have another IO gov, but I try to optimize it first and test it extensively.
additionally this kernel now includes the IO sched switcher from @Sultanxda
Description is as follows:
"This driver changes the I/O scheduler for a specified request queue to
Noop when the screen turns off in order to improve power consumption while
the screen is off, as well as reduce resume latency when the screen is
turned back on. After the screen is turned back on, the driver will change
the I/O scheduler back to what it originally was after a 10000ms delay."
This means screen turns on faster and phone will drain less battery when in deep sleep. :good:
In addition to boosting DDR bandwidth we now also give a boost to our storage when the screen gets turned on.
Changelog 0.2_2:
- included maple IO scheduler from @frap129
- included IO switcher from @Sultanxda
- boost ufs storage controller when turning the screen on.
- included BLN from @tbalden ( give him a big thanks!)

I am currently on viper rom because I had to test if the kernel runs on the new base.
*** This kernel is now end-of-life and not supported nor actively developed anymore !!! ***
Hi all,
some of you know me from the other OnePlus or Samsung devices areas, where I provide my kernels already for more than five years to OnePlus 5, 3T, 3, 2, one and X, Galaxy S5, S3 and Note 10.1 users for all sort of platforms (Samsung, Cyanogenmod, Omnirom etc.)
Now I own a OnePlus 5T device and decided to port my kernels also to this device.
Please note:
I am not heading to have as many features as possible implemented, this is not my design goal. If you are more into that, move on to other, good existing kernels. If you are searching for a good mix of improvements and new functions while not sacrificing stability, you are welcome here (see below the history section for more info).
Compatibility
Important: This kernel is only meant to be compatible with official OnePlus OOS and nothing else.
So when the kernel does not run on custom rom XYZ, do not even bother me with it or ask hundred times in the thread for compatibility.
I could not care less about it !!
To add: A community build is NOT an official build supported here. If you use a community build and have issues, don't complain or even report.
Important notes
Read first, especially when you are new to my kernels:
http://wiki.boeffla.de
Boeffla-Kernel uses the anykernel concept = Flash stock kernel of rom first !
This kernel is ONLY compatible to OxygenOs stock, nothing else !!!
If you are using a custom rom that bases on OxygenOs, it might work. However, if it does not work, do not expect me to do tweak to make the kernel running with your favorite rom. I would not do it - my one and only reference is OxygenOs stock.
It is not supposed to be compatible to CM, HydrogenOS etc.
Also note: You have to use Boeffla-Config app which I provide on my homepage to tweak the kernel. 3rd party apps will not be able to unleash the full power of the kernel.
Important: Manually disable battery optimisation for Boeffla-Config app in the rom settings (battery -> battery-optimisation)
Installation
Read the install instructions in the support section on the Boeffla Site.
Support
First read the FAQ section on the Homepage !!!
Click here to learn about all possible kernel settings in the config app (outdated at the moment).
Click here to learn about using the config app.
I will refuse to give support if you do any undervolting/overclocking and experience freezes or hot reboots.
I will also not provide any support if you do not use Boeffla-Config app to tweak the kernel, other 3rd party tweaking apps are known (and intended) to cause issues.
I will refuse to give support if you have xposed framework installed and reporting any kind of weird issues. My opinion to xposed it quite clear: too powerful for >90% of the users that just mess up their system with it.
Otherwise, you can get in touch with me via the support e-mail address: [email protected]
Please provide kernel version, rom version, a detailed issue description and ideally supporting screenshots or log files.
Change logs

Features
Note: This kernel only runs on OOS 4.x.x for the OnePlus 5T - nothing else !!!
Important: Manually disable battery optimisation for Boeffla-Config app in the rom settings (battery -> battery-optimisation)
Support of anykernel concept (only latest kernels) - flash stock kernel before flashing Boeffla
Full integration with Boeffla-Config V2 (you need at least version 2.5.10 or higher !!!) configuration app (get it from http://www.boeffla.de) to configure all kernel settings
Dash charging fully supported

Additional governors: zzmoove, blu_active, impulse, cultivation
Additional schedulers: fiops, bfq, sio, sioplus, fifo, vr, tripndroid, maple, zen
Underclocking CPU and GPU supported
No CPU and GPU overclocking (not planned too)
No CPU and GPU voltage interfaces (not planned too)

History and design targets
Basically I created my first Boeffla-Kernel in 2012 as there was no kernel for the Samsung Galaxy S3 around that had exactly the mix of functionalities that I wanted. I wanted to have full flexibility in undervolting and charge rates for instance, but did not like the sharpness and/or brightness tweaks many kernels have implemented as per default.
Hence, I began to create my own kernel after a while, adding all the features I like. This is the result of my work, which in the end I decided to share with you. I hope you like it as much as I do.
The objective of this kernel is to have a kernel for daily use. It does not aim for best battery life, or best smoothness or best benchmark scores. Also it does not aim to have the broadest feature set available everywhere.
It aims more for a good mix of all, not sacrificing stability and functionality in the end.
And - most important: It aims to stay quite close to stock !!!
These design targets are also valid for the OnePlus kernel here!!!
This said, I will definitely NEVER implement:
things I do personally not need
things I do not like
things that are in any way dangerous
anything which is highly experimental
a CAF based kernel
anything that requires upstreaming of kernel parts to a higher kernel major version
So do not even ask for it if it falls into the listed categories. Everything else I am happy to check and decide.
And: I do not really care about benchmark numbers, they say almost nothing as long as something is not completely wrong. Important for me is the feel-good factor.
I am also not interested in gaming at all, so never expect a gamer kernel. It will just not happen...
Compatibility
To reiterate it again: Flash the kernel only if you are running a compatible rom !!!
Configuration of the kernel
To tweak and configure the kernel, manually load and install the app Boeffla-Config V2 from the downloads section on www.boeffla.de.
You need at least version 2.5.10 or higher for the OnePlus 5T Boeffla Kernels.
Donation
If you like my work, feel free to donate: Donation-Link
If you donate at least 2,49 EUR (to be in line with the donation app prices on Google Play store), you will receive a personal donation code which unlocks some nice little comfort functions in Boeffla-Config V2 on top.
Source code
All sources can be found in my Github repository: http://github.com/andip71
Credits to developers
Of course, I had never been able to create all that by my own. So I want to give credits to the really good developers around, that have given me all the inspiration and from which I cherry picked lots of the implemented functionalities:
* ZaneZam
* eng.st
* flar2
* arter97
* Grarak
* Entropy512
* Faux
* FranciscoFranco
* Ak
* Osm0sis
... I just hope I did not forget someone. If so, please let me know and I will add you of course.
Thanks to all of you for your great work !!!

*** As always - Flash on our own risk! ***
Make sure you flash the correct version depending on your firmware version!
I can and will not take any responsibility for bricked phones or lost data.
It is generally recommended to run a complete Nandroid backup in your custom recovery and safely store your personal data before you flash a new kernel.

Not sure if it is the same problem but in the first release of elementalX kernal, whether the brightness dimmer was enabled or not the brightness at maximum was half of what it should have been.

Ok, issue analyzed, confirmed to be a bug.
Bug is fixed and beta2 already compiling. Stay tuned. And thanks for the report.
(BTW it was not the brightness dimmer but a changed brightness range sent by the rom to the kernel, so the min/max limiter was cutting too early)
Thanks

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..
