Quick question. So the kernel runs at a default of 1512mhz right? And you'd have to manually set it to 1.9ghz if you'd want that speed? Was hoping someone could clarify.

Thanks for clarifying mate. I just flashed it and I'm going to leave it running the way you set it up, don't see a reason to stray away from stock settings. Everything is running smoothly, good job on the kernel man.
I also just noticed that all the default settings are highlighted in bold silly of me to not look properly

Testing this out now, love Franco kernel so this should be a nice kernel to use until he gets his hands on a flo
No issue with root loss for me running CM with superSU, battery is at 92% with 1hour 10min screen on so is looking pretty good, and has been a lot smoother than Faux kernel!
Hi Guys,
Sorry was away on holiday... Got back a day ago - Probably not the best timing for a kernel release

So I look to have resolved the root issue. (fingers crossed)
Can you please give r8 (download here) a try and report back. You will need to flash ROM first if your still on r7.
Have tested it myself, looks to work OK on cm10 and stock.
Thanks
Trying r8, everything seems fine so far, kept root too However I would suggest people try ondemand instead of interactive, it gives as good performance with fewer random CPU spikes and no insane ramping on touch, it's what the nexus 4 uses by default now and i think it's the best balance
with r8 root is working just fine
Hello guys, I just wanted to know how it's going with this Kernel since I'm considering to try out some Kernel's.
Thank's in advance.

Hey @jekk0s Thanks for that.

Is your Git source up to date? I just built your kernel and the version I built has a few less CPU governors then the .img you uploaded
Other then that Kernel works great! Compiled with UberTC-4.9

Think the default governor might not be the best. I'm using intellidemand which makes the phone work smoothly in most situations.
Works great on CM12.1. Is there anyway that I could set the minimum GPU frequency on boot? Maybe using an init.d script?

Very VEEEERY good work . Love the overclock 2.1 GHZ !!!!!! i can see the difference in games . work on Exodus 5.1.1 2016 but , lagging on music , unloking or keyboard use . higher GPU frequencies can be use ? Like 500mhz ,or like same sense kernel (587 MHz :0 )
Sorry for my english ^^
which software you guys using for tuning kernel.
I tried several, after restart its resetting some times even after exiting the app. I am encountering frequent restarts and higher temperature.
Tried clean, still issue persists. I can't live without double tap to wake and sweep to sleep.
Device being secondary, not interested in much performance , I just need basic features and stability. I tried under volt the cpu , it didn't boot then.
Was on ARHD and elementalx before. Was going good.
Recently jumped to cm.
Any suggestions?
I use Ex kernel manager for change my CPU and gpu frequencies , active fastcharge , ....
I hope that the next update propose more gpu frequencies , the currents , and more higher really more than 450
On exodus rom the phone seems stable , but lag on internet or music use (unpleasant) :/ I've try differents gorvernor but no real change ...

Flashify should work fine. I used it myself.
This kernel fixes the TOUCHSCREEN FREEZING bug when playing large games by removing the CGROUPS.
Which also gives us back the RAM it ate (458mb total, now)
Same features with LahKeda's overclocked kernel.
1200mhz Overclock
Kernel Sampage Merging
zRAM
Governors
No bugs.
Source
Credits:
@psych.half for the source
@LahKeda for adding overclock and compiling
(no credit for me. I just found out cgroups is buggy but all the work was from them)
thx so much ive been waiting for this for so long
New Build
Increased zRAM from 92mb to 134mb
Properly enabled KSM (It was included in the previous one but it wasn't enabled by default)
Compressed into boot.img
Set the maximum frequency to 1200mhz by default
Set the minimum frequency to 600mhz by default
Set the governor to "ondemand" by default (If I set "performance", the frequency will only go to 1000mhz even though the script was 1200mhz. I don't know why that happens)
So which kernel is better?... Cm11's default one or this one?
Please provide the sources

Tried it on corpish's last cm 11 build and works fine..
Actually earlier I was using this kernel in slimkat:laugh:
Just bcz of few bug's!!! I reverted to cm 11
Anyway works on CM 11
Thanks again
New Build
Added 1250MHz overclock (no reboots, see uptime)
Enabled memory control cgroups (enabling cgroups fully was causing freeze in playing games so I tried using just the memory resource controller and it works without freezes, cheers)
P.S. Tell me if you guys want governors. I forgot to add it. Only performance is in this kernel.
Nevermind. Here is it. Same as above but with governors.

Can u suggest the best custom rom for this phone?
EDITED: Freezes at 1.3GHz after over 30 hours. If you still wanna try it, I'll keep this here. This build has lowered voltages.
I don't know if I can find a way to get it to work but I'll try anyway.
Final Build
Lowered voltages (Battery life increased)
Updated lowmemorykiller driver (cherry picked from this source)
Unfortunately, 1300MHz was unstable no matter what. Tried different sources, adjusting voltages etc but it seems to be the limit for this device. Also ive noticed some weird artifacts whenever I use it (Which proves that it is unstable since in PC overclocking as well, the cue for unstable overclocking is artifacts)
TLDR; 1250MHz is the farthest we can have.
Deleted. I'm losing my mind.
Try this guys. 1292MHz, Hopefully this would be the last build, After almost 4 days constant, still no reboots.
Edit #1: DO NOT set the governor to ONDEMAND. Performance is perfectly stable but when I set the governor to ondemand, after a couple of hours it rebooted. I don't think this is coincidence with over 100 hours of uptime.
Edit #2: Reuploaded the kernel but this time, performance is the only governor option since it's the only stable one. If you want governors, download the 1250MHz version.
how to overclock
hey buddy,
I have a question, I have rooted my phone it is running android version 4.1.2 and i want to overclock my phone. Can i use this kernel in my existing os version or i have to install cm11 and then overclock it. Please tell me in detail, i am new in rooting and flashing and all that. Please explain in as much detail as possible. Hope a response from you.
Thank u
My model no. GT-S5282
This kernel is the result of a common work with @Leicxan. It can only be used on H990 and was successfully on single sim AND double sim variants. D.O.T.S. kernel is :
- Dirty Santa rooted
- Optimized
- Tweaked
- Stock based
Caution
Nor @Leicxan nor I are responsible for any damage caused to your phone. Any of the action you'll make to flash a kernel theorically voids your warranty. If don't accept any risk, then keep your stock phone
Content
- Based on v10g official LGE sources
- Compiled with UBERTC 7.x Linaro 7.2.1 (since V1.4)
- Dirty Santa root as implemented by @emdroidle
- CPU Governors : performance, powersave, userspace, ondemand, conservative, interactive, darkness, nightmare, zzmove, blu_active, elementalx, chill, dancedance. Default is interactive.
- I/O Schedulers : noop, deadline, cfq, fiops, sio, bfq, zen, maple. Default is zen.
- TCP congestion protocols : htcp, cubic, bic, reno, westwood. Default is westwood.
- Adreno idler
- Adrenoboost
- Exfat Support
- KCAL
- RCTD removed
- Wakelocks management
- Various small optimizations and tweaks
History
V1.0 [11/10] : original version
V1.1 [11/22] : CPU frequency hard limit (for battery drain improvement) and various minor fixes
V1.2 [11/27] : CPU frequency fix, exfat from samsung's open source module, LGE adaptive readahead
V1.3 [12/11] : Upstream Kernel to 3.18.86 thanks to @thirdzcee. Disabled LGE's rctd, ccmd and triton. Disabled some debug configuration. Note : Windows Defender can detect the archive as a Fuerboos trojan, this is a false positive.
V1.4 [01/04] : Fix for kernel crash when using pptp vpn. Upstream Kernel to 3.18.90.
Installation instructions
Follow the instructions provided by @emdroidle here : https://forum.xda-developers.com/v20/development/dirtysanta-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/development/tool-kdz-writer-t3649818
Known bugs
Some users reported issues with SD cards formated with exFat. This is not a general issue. The root cause is not clear (linked to the way the SD card is formated ?).
How to report a problem
It is very important to provide as many details as possible when you report a problem. It means providing :
- the model of your phone
- the version of the kernel and of the KDZ you updated to
- a precise description of the problem and of the circumstances
- logs (logcat & dmesg) : https://forum.xda-developers.com/showthread.php?t=2185929
Q&A
Before asking please :
- read the posts in this thread. The "Search Thread" box is your friend.
- have a look at @xdav20's H990DS Info Bank thread which is full of usefull information : https://forum.xda-developers.com/v20/how-to/h990ds-info-bank-t3703736"
Thanks
@emdroidle for his implementation of Bad Santa on H990
@USA-RedDragon for his werewolf kernel that was inspiring

Can we flash this over an existing kernel via TWRP if we have already rooted?

Click to collapse
Normally yes.. But if there is a problem, you'll have to restart all over, so make a backup of your phone, just in case..
It would be nice if this can be crossed over to H918.
First of all, just want to say thank you to @jahlex and @Leicxan for bringing the long awaited kernel with literally everything I could ask for to our devices.
Upon first install by flashing in TWRP, wiping dalvik/cache and rebooting, my phone goes to the LG screen, then black screens and I get a kernel crash screen that I've taken a photo of here
Any ideas what's causing it? My system version is in my signature. I'm really keen to get this working! For now I've restored my TWRP backup I did before flashing, back to 0.2.3b
Update: Even after the TWRP restore I was still getting the same problem. Immediately I thought it might be a Magisk problem as that's the only other thing I updated before rebooting. It appears I was correct. I used KDZWriter to re-flash the boot & system partitions of my phone (since Magisk modifies the boot image) and it immediately booted okay with my TWRP backup. Booted back into recovery, flashed the kernel as well as a previous Magisk version (14.0 not 14.2) and my other /system apps & mods, wiped cache, rebooted and sat on the LG screen for a while. Then booted into the OS okay. Glad it worked out and I'm keen to see how this kernel goes.
On a sidenote, do you have any plans to bring it to a more up to date version of the linux base kernel?

Magisk 14.2 and 14.3 are beta version, I tried magisk 14.3 but my h990n always boot into bootloader interface..
So just stay with magisk 14, it doesn't have any issue.
For the Linux version, it will take tons of time to do this even we just upstream our kernel (from 3.18.31 to 3.18.79)

Yeah I don't know why 14.0 prompted me to update to a beta version. I know 14.3 added something to do with supporting LG devices better, maybe that broke something. Otherwise I'm quite happy with how things are going ?
And yeah I'm somewhat familiar with how long kernel related things can take, it was more of a question if anything.
I've just installed it now, it works perfectly for now much more reactive i've impression Thank you!!

This is major evolution of this kernel. DirtySanta-h990-1.2-u721-v10g was basically the stock v10g kernel with Dirty Santa root.
Before all, thank you so much guys, that's a great work
For some opinions i have many friends that buy h990ds last year and me too, we concluded if tha kernel was more optimized battery side was more effective than performances, and will be great that CPU and GPU clocks and voltages will be more unlocked if you can do that , thank you again.
great kernel thank you @jahlex :good: and @Leicxan :good: it works perfectly

They've already enabled some overcooked frequencies with this, as seen in their Github commits. If it's battery you're looking for, install the AKT Profiles from the thread, and then choose a balanced or battery saving profile. Since installing those and this kernel, I'm regularly seeing 5-7 hours of screen time.
On a side note @jahlex or @Leicxan if you're looking for a beta tester, feedback, or Guinea pig to help out (that isn't actually building the kernel, that's above my ability to simply modify individual files) I'd love to help wherever possible
Been doing the whole TWRP/Flashing/Kernel/ROM thing since I got my G3 way back in the day.

As @iDefalt said, we already enabled higher max frequency / voltage for both CPU & GPU. We won't go higher because the result would be high risks of unstability and overheating. If you want performance and do not care about battery life, simply switch to performance governor for both CPU & GPU. We use interactive CPU governor by default because it is a good choice considering balance performance / battery life (nightmare & darkness are good choices too). You have plenty of apps to do that, example : https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor.

Been doing the whole TWRP/Flashing/Kernel/ROM thing since I got my G3 way back in the day.

Huge thanks guys! Everything works great, even video recording. Great work!!!
@jahlex @Leicxan
Thank you for the release. I will report back any noteworthy issues.
Please forgive me if the following comment may deemed as a thread hijacking. I would be happy to remove it on your request.
I have just started a new thread in time for H990DS users and others, with useful information and tutorials that would potentially answer the most commonly asked questions or the issues sooner or later you would run into.
Kcal is so nice to finally have, thank you c:

Introduction
Hey guys! This is the kernel myself and my good friend APOPHIS9283 have been working on for OnePlus 5/5t.
- Kernel only supports custom ROMs - final OOS version of 1.0.17 from 07/03/2018 is here in the OP, as is.
- Kernel will always be kept upstream to latest linux-stable
- We do not shy away from features around here. This kernel is LOADED! If you want something minimal, this is not for you. !
- If you have issues, we need logs! If it is an issue that is not able to be logged for some reason or another, please give detailed steps on how to replicate the issue. No logs = no support! Help us help you!
Features
- Upstreamed to latest linux-stable
- Governor options including: alucard, tripndroid, cultivation, impulse, chill, blu_active
- Overclock and underclock support. Kernel boots/defaults to stock frequencies though.
- Dynamic stune boost
- Adreno boost
- Adreno idler
- Wireguard support
- Sweep2Sleep
- LED Settings
- High brightness mode
- sRGB
- I/o schedulers including maple, deadline, bfq and tripndroid
- USB fastcharge
- Boeffla Generic Wakelock Blocker
- TCP congestion avoidance algorithms - Too many options to list!
- Backlight dimmer
- KCAL color control
- Sound control
-i/o switcher
- More I probably forgot, but you get the idea!
Installation
- If on a custom kernel, dirty flash your ROM. Reboot to recovery and flash this after booting with ROM's baked in kernel.
- If on ROM's stock kernel, just wipe kernel app data and flash this in recovery. If needed, flash no-verity after!
- Upgrading from one version to another is as simple as flashing the kernel and no verity if needed. I do recommend wiping kernel app data on each flash - we add things often!

Oh snap!!!! LOL
I'm a hardcore Franken kernel user but I'm going to back that kernel up and give this a shot. It's the first kernel that's intrigued me in a long time. Franken is the standard best kernel for me, so it means something if I can be swayed by your work.

I started with a fresh base from Flash kernel (huge thanks to him), and built it with my idea of how a kernel should be IMO and with user feedback.
Hope you enjoy

All the best with this kernel, especially as its aimed at custom roms rather than OOS.
When Paranoid Android Oreo hits, is there any possibility that you and @wrongway213 would consider doing a version for that ?
If not, then no problem

That would be very nice, if it were possible.
Thanks for the consideration.
That is of course if Paranoid Android Oreo ever materialises...LOL
If you are on a ROM and had broken gestures. Will you flash this and see if it doesnt fix them
Yea this Kernel is great stuff. Can't recommend it enough... I trust it's creator and it works solid. Good job @apophis9283

Gestures should work for all ROMs. Let me know if they don't. A few other tweaks I wanted to get in there. Just wipe your kernel app data. To match my settings just use tripndroid governor.
@wrongway213 what custom rom do you recommend for best kernel effectivity? thanks

I don't think he's tried anything else. I have. I flashed AICP, and CRDROID. Both ran perfect. I like it on LR but I'm not sure it because the kernel is better on one or the other. Just what I prefer to use. I had to flash other roms to make sure everything was working.
This was taken while on AICP. I find this is generally what stats I get
Tested with Aicp, validus and omni all works great
Hi, all XDA members, I built a light-weight kernel for our little monster (hammerhead).
My kernel is based on Unlegacy Kernel. I optimized the kernel for best battery life and performance balance. I tested it on AOSP Extended ROM. It should work on LOS too.
Features:
-Intelliactive governor.
-SIO scheduler.
-25mV Undervolted manually from acpuclock source code. (Only for PV2 CPUs)
-More cooler device.
You can download img from Google Drive link. Flash it via TWRP or fastboot.

Awesome, I'll test and feed you back
thanks for your work
Detail please for features? Thanks
For this build, kernel comes with intelliactive governor.
I will add some features and improvements for best battery life and performance. (In next build i will undervolt it and i will add more governors, I/O schedulers)
Changelog:
(v1.0.2)
-Kernel name banner fixed.
-25mv Undervolted for PV2 CPUs.
(v1.0.1)
-SIO is the default I/O scheduler.
Testing
Can someone confirm that kernel works with LOS?
thanks for the new kernel, but no work in DU 12.2 flashed via twrp.
Any chance you could have your kernel fix phonecall bluetooth audio? It's bugged on every custom ROM right now and it's been theorized it's a kernel issue.

Here is some info on it: https://forum.xda-developers.com/go...nlegacy-android-project-t3593425/post75688720
Xaif fixed a problem with video recording, you should include it in your kernel.

How i should flash it?
Like "boot" or "recovery" ?
Its a kernel it goes flash it as a boot IMG
I flashed this with AEX ROM and it hung at boot
Will a custom kernel enable NTFS and exFat support on Oreo?? No ROM currently works why either of those so u can't use my external hard drives.
Flashed 1.0.2 kernel over us 8.1. The undervolt sold me! If possible, and if you're entertaining ideas, I'd greatly appreciate usb fastcharge support.
I've heard the arguments against it, but in two years I'd never had a problem.
Will it work on Nougat (Los 14.1)?

Is this kernel dead?
Edit: @metahex12 Can you consider adding support to Pie (Unlegacy CAF ROM)?
