Hey @jekk0s Thanks for that.
Just 1 Q
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
Thanks again.

I've updated the github with some more local changes. To enable the governors you'll need to use the m7_defconfig

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?

will the kernel work with android m, please?
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 ...
Do I need to flash it using the command line or can I use Flashify for that? [emoji4]

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

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!

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

Overclocked kernel T530
I have compiled two variants, one for the 4.4.2 rom and another for 4.4.4, CM11 rom.
4.4.2 kernel is tested on the stocklessv5 rom.
The overclocking in this kernel is experimental. Some also claim that overclocking is not possible on this device.
I still feel that there is a speed improvement using my kernel, so whether this comes from the overclocking or from other changes is debatable.
Antutu tests have given me slightly higher scores on the stockless rom than on the CM11 rom.
On stock rom I did get Antutu score at 16800, at the stocklessV5 18367. (these are numbers I have logged a while ago, offcourse results will vary from test to test with antutu.)
On my kernel I typically get around or just below 19000. (highest score so far is 19200)
There is a thread regarding overclocking the LG G2 mini, and I have been looking at the github for that project for ideas.
LG G2 Mini use the same cpu/gpu hardware as the tab4. For comparisation there is posted an image in that thread by someone showing antutu result of 20000 on the LG. But others report they can not replicate that. The LG have lower screen resolution than the Tab4 10.1" so that could explain some of the difference.
About this kernel:
- Overclocking CPU to 1.6Ghz
- Overclocking GPU to 533Mhz
- DVFS is disabled
- Fixed the simple_ondemand GPU govenor crashes
- CPU governors smartassV2 added, enabled interactive govenor
- Compiled with sabermod 4.9 graphite toolchain
For sources, look at github
The 4.4.4 (CM11) kernel: https://github.com/amyren1966/android_kernel_samsung_matissewifi

I have been trying to make one for cm12. But my attempts resulted in a non-booting kernel, so I put it aside for the moment. Perhaps later if I have the time.

I dont know what happens if there are no framebuffer?
But after installing my kernel and I rebooted it just shows the first samsung boot screen, and then goes black, then after a short while it just relaunches twrp recovery.
Other atempts it does go directly to the download mode.
I'm very excited to hear this news. Can anyone confirm if the oc is for real on cm11 or kk? and if so, we must have it working on cm12 for sure. cm12.1 is actually what we're on isnt it? blisspop here, but i see a 5-12-2015 cm 12.1 just dropped so i'm pry gonna run that in the next day or so. Either way, great work! Any type of improvement i see as progress.

hi, please about 4.4.2 with stockless rom v5, if anything become unstable and want go back to previous kernel is it enough to dirty flash stockless rom or there is something that must be deleted manually?
thanx a lot…
thank you can this thing get overclocked more i mean i saw people state they overclocked the tab 1 to 2ghz just asking lol, anyways great job

Finally someone developing a different kernel! Very much appreciated!
Take a look at ExtremeKernel, it adds some bits missing from stock Kernel that would be nice to see here (Extreme seems to be discontinued).
Gonna follow this thread and try it!
@bodafranus thanks for a great kernel! Working here o a40 sd 415 indian variant. Here one bug though.. touch response is not working on ambient display.. it has been fixed in latest commits by Karthik. Kindly include these fixes in next version. Thanks!
Waiting for Alpha1 to try it! When will it be available?
Changelog seems to be promising!!
New version:
alpha1
1. changed governor and HMP scheduler values.
2. added bw_hwmon shenanigans to ramdisk (responsible for controlling some bus frequencies)
3. updated some drivers
4. merge 'caf/LA.BR.1.2.9_rb1.12' (kang from: karthick111)
If you experience any problems, send logs. (some can be found at: /sys/fs/pstore)

That's strange, can you try flashing over latest official Lineage, after a Factory Reset wipe?
Try to grab a logcat while in bootloop, if it persists (see: https://forum.xda-developers.com/showthread.php?t=2274119)
I will check Ambient Display after I fix some issues.

Ok.. I tried it on official lineage 10/4 build with fresh flash and the lm kernel alpha 1 is working without any problem like bootloop/stuck to bootlogo.
i am not using this kernel even not other, but having big trouble with lineage OS, basically cpu core bug i can say and i asked on its respective thread, page 72 and 73, dev and other users helped me but partially solved you can refer if you want to, but i will explain anyway here shortly,
i am using 20170410 built, and kernel adiutor, selinux permissive, i tried switching all possible options like core control, clock speed, governor, other thing, the only thing bug me is governor, like interactive and ondemand, max 1497mhz and min 200mhz i set, but it always on 1497mhz when even idle little process and core directly goes offline when no use, and never downclock, i also found too much over heating when any games or heavy task.
(**this is not bug of this kernel,
and this exactly same paragraph i'll be posting on lineage os thread, so if you like to suggest me about this bug you can in that thread )
so back to main track, will this kernel solve this problem?
also i see alpha 2 change log but no built.

Wrong thread. If you demand CPU power obviously it'll deliver, so expect it with heavy tasks. Overheat is a problem inherently of our device and its chassis, after all metals are good heat conductors...
Check your target_loads and background processes if you encounter this problem while idle.

really appreciate , i am gonna try this right now and sure will giving you some feedback, thanks.
quick feed, changes i see. A46 device
- little cores working very good as expected now, clock speed interactive as on demanded, which i prefer.
-but big core just stay at 1497 mhz constant (which i know its not problem on this kernel, it from lineageos rom that why i tried using this kernel to see fix) but i know someday may be solved by this kernel,
-one more thing i notice on small core, as its clock speed is as on demanded, but all 4 core speed same, instead of individual.
-now no core get automatically shutdown, even if no demand of an individual core. which is good as well as bad (i am kind of confused for this)
that all, this changes i looked as after flash just now.

-but big core just stay at 1497 mhz constant (which i know its not problem on this kernel, it from lineageos rom that why i tried using this kernel to see fix) but i know someday may be solved by this kernel,

-one more thing i notice on small core, as its clock speed is as on demanded, but all 4 core speed same, instead of individual..

actually, its kernel adiutor doing, when i used cpuz, it showed all cpu at 200mhz which i set, and kernel adiutor need 2 full speed core to work smoothly, so kernel throttles to max clock speed of all 4 big core, instead of 2,
so far i am happy, thnks :good:

How is the battery usage in this kernel
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

Tested on SlimKat but it "should" work on cm11 since the source is the same. Try and report back if you can.

@RJinxed
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.

Do you think u can upstream our kernel?
Just a thought :silly:

To be honest, I don't know. All I do is follow lahkeda/corphish's commits in their github. I just learned to edit defconfigs and compile but aside from that, I don't really know what to do.

Same here
I've never compiled kernel for star but for my other device I did
I'm happy to learn stuff :laugh:
Anyway I was never successful enough to upstream my kernel hope u'll be able to do it in future:fingers-crossed:
BTW thanks for the kernel

Hey buddy, I have installed CM 14.1 custom rom. Will this kernel work?

No, this is only compatible for kitkat roms. Also, don't use cm14.1 yet since it's still really buggy.

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
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.

Source code: https://github.com/metahex/android_kernel_lge_hammerhead
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)?
