[KERNEL] [GCC4.8] ThunderKat Kernel | Android 4.4.4 | Nexus 10 | 2014/08/24

Donning a new name in favour of the new delicious version of Android... Welcome to the ThunderKat Project!!
Heavily based of my Flaming Monkey kernel configurations and the stock AOSP kernel source, here's my standalone kernel for the Nexus 10. I will maintain this independently.
It will always remain close to the AOSP exynos kernel for manta (Nexus 10) with a few useful tweaks and additions, but will not have any OC/UV, colour controls and any advanced customisation options. It is a stable kernel and will not have frequent updates.
This kernel uses the AnyKernel method and is ROM independent. I have tested this on 4.4 (Stock & AOSP) based ROMs.
Features:
1. Linux Kernel 3.4.39.
2. Based on AOSP KitKat MR1 kernel source for exynos/manta.
3. Built using the Google ARM GCC 4.8 toolchain with -O3 CFLAGS & AFLAGS optimisations & ARM Cortex A15 build optimisations.
4. Enabled Conservative & Powersave CPU frequency governors (in addition to Interactive, Performance & Userspace). Interactive set as default.
5. Preserve correct sysfs permissions on governor change.
6. KSM (Kernel Samepage Merging) support.
7. NTFS, F2FS, EXT4 xattr (extended attributes) support.
8. Networked file systems support (NFS V3, NFS V4 & CIFS).
9. HIDRAW support (supports non-conformant HID devices).
10. Support for more input devices (keyboards, mice & joysticks) including Logitech Unifying devices.
11. Support for USB serial modems (PPPOE).
12. Support for multi-card readers (multi-lun devices). This allows you to mount multiple cards using a multi-card reader. May need an app like StickMount. (Credit @nvertigo67)
13. Removed SWAP support.
14. Removed some un-needed debugging.
15. Increased thermal throttle limits
16. Scalable CPU frequencies
Changelog [2014/08/24]:
1. Built using Graphite optimized GCC4.8 toolchain
2. Added ROW & SIO I/O schedulers
3. Set ROW as default I/O scheduler
4. Upstream F2FS changes
5. Miscellaneous I/O improvements
Changelog [2014/06/05]:
1. Update to AOSP 4.4.3 kernel source (kitkat-mr2)
2. Added F2FS filesystem support
Changelog [2013/12/15]:
1. Update to AOSP 4.4.1/4.4.2 kernel source (kitkat-mr1)
Changelog [2013/11/21]:
1. Initial release
Information:
1. Flash using a custom recovery (TWRP/CWM).
2. This kernel is ROM independent and uses the AnyKernel method. Hence it uses the current ramdisk. You may have issues if this is flashed after a kernel with a custom ramdisk. If so, reflash your ROM and then flash this kernel.
3. Needs an unlocked bootloader.
4. Make sure you have at least 50% battery charge before flashing this.

Very cool! I will be trying this tomorrow, will have time to play with it. Nice to see KSM in it.

Nicely done. I'm running your kernel as we speak--snappy, snappy! No issues so far. :good:
Only thing left to do now is give it a catchy name like: "The CRAIGINATOR"

Wow, great news, thanks craig!

Thanks...and yes, I will be renaming my ROM and kernel to something more... well, appealing... when I restart the ROM project...

Once I'm at 50% I'll be all over this like a rash

Great job, runs great! Only issue is it defaults to cfq scheduler on boot even when I have it set to run deadline.
More of a preference than an issue.

This kernel is really good, I was very impressed by your previous Rom and look forward to the new Rom you said will be released later in the year (hopefully!). Your hard work is much appreciated. Using your kernel with Carbon Rom right now and it seems very stable.

this kernel works best on my N10. no reboot, no SOD and no battery drain.
my tablet is 10 days up without a single problem or recharge! :good:
i hope it will be continued in the future!

Yes, I will continue supporting this kernel... though there will not be many updates... the aim to to remain close to AOSP, yet provide some useful tweaks and additions... I will be building a newer version soon (having problems with the cross compiler on my work laptop, else I would have done it today)...

Hi!
Can I flash this kernel to the stock ROM?
And revert back when new android version comes out to OTA update?
Thank you

Yes, this will work fine on stock...and you can easily revert back using the boot.img from the factory images provided by Google...

Updated release in OP...

Does this have the latest wifi and or gpu drivers? I know wifi drivers are kernel level, not sure about the gpu though. Anyways, its a very nice and smooth kernel. It's been a baron wasteland in mantaland. I guess Google didn't sell many of these.

I just installed the kernel, very smooth, I was having shutdowns on Trinity latest and RootBox. Hopefully is not a ROM problem and this kernel fixes it, I really like RootBox.
Thanks for the awesome work and support.

I have yet to incorporate the updated wifi and gpu kernel level drivers... I will be working on these soon...

Anyone here with sufficient kernel knowledge to merge the updated mali graphics drivers (http://malideveloper.arm.com/develo...n-source-mali-t6xx-gpu-kernel-device-drivers/)... There are a few updates that are beyond my kernel & C/C++ capabilities... like osk has been replaced by kbase... Please PM me if you can help!! Thanks!

Great work on this kernel! First time reaching 9 hours on screen time. Paired with Mr Robinson AOKP.

[Kernel][TW][AOSP][KK][JB]MaxFour GT-I9500 (5410)[v14]

The first time I made AdaMax was for the Chinese Galaxy S4 Duos GT-I9502. I ported Adam kernel and added more tweaks from other kernels like Persus, halaszk (5420). After several releases, I decidec to spread this kernel to more models. So I built the v8 for both Chinese and international GT-I9500. This thread it for hosting it.
This week, i successed compiling for the s4 with 5410 cpu. As we know GT-I9500, GT-I9502 and SCH-I959. They share almost same compiling configure and their own ramdisk. So I compile them together with almost same features.
At last, I have to make following declarations, AGAIN:
Take your own risk and responsibility on flashing this kernel. I am not responsibale for any loss of your hardware, software, data or warranty.
Read this OP from start to finish before flashing the packages or asking any questions. There is a Q&A section. Any questions already answered will be ignored by me and may be insulted by other members. So save your your keyboard, your time and your data traffic.
No ETAs.
Don't ask me to make this kernel for a specific rom. There are basically only two kinds of roms, AOSP and TouchWiz. So I compile for these two kinds with differnet SDK levels. If it dose not work on some rom, don't blame me and ask me to adapt the rom for it.
If you found a new version, but its download link is not directly showed in this OP, that means it is a version I don't think good enough to be a release. So take your own risk to use it. I will remember your feedback, try to make changes, but not respond with posts.
Thanks to a lot of people, I will add their names here... @wanam, [email protected], @Dees_Troy and Team Win, @AndreiLux
As my habit, I always put the download link first:
v15: https://github.com/maxfu/android_kernel_samsung_exynos5410/releases/tag/v15-9500
File name instruction:
touchwiz: for most used international GT-I9500 with exynos5410 cpu.
aosp: for AOSP KitKat 4.4 roms like CM, ramdisk comes from CM 11
kk442: kernel for KitKat 4.4.2
jb43: kernel for Jelly Bean 4.3
jb442: kernel for Jelly Bean 4.2.2
lite: live version is built with stock zImage and maxfour initrd. It has limited maxfour features. And sometimes selinux f**ks up the STweaks.
boot: system kernel package
recovery: recovery kernel package
kernel: system + recovery combined kernel package
*.tar/*.tar.md5: Odin package
*.zip: CWM/TWRP recovery package
example.1: boot-i9500-aosp kk442-v10f1tc.zip means a system kernel image CWM/TWRP flashable package for international I9500 with TouchWiz KitKat 4.4.2 roms.
example.2: kernel-i9500-aosp-kk442-v10f1tc.tar.md5 means a system recovery combined odin package for international I9500 with AOSP roms like CM.

https://github.com/maxfu/android_kernel_samsung_exynos5410/wiki
https://github.com/maxfu/android_kernel_samsung_exynos5410/releases
I open the issue section for the source code, you can report problems here. Please provide at least version aosp/touchwiz jb/kk.
https://github.com/maxfu/android_kernel_samsung_exynos5410/issues/new
The source code:
You can
git clone https://github.com/maxfu/android_kernel_samsung_exynos5410.git
git clone https://github.com/maxfu/initramfs_samsung_galaxy_s4.git
git clone https://github.com/maxfu/toolchains.git
use the build.sh for exynos in toolchains/script ro build the kernel.
you need to su before build the kernel cause the ramdisk belongs to root.
Since this is a side product of my kernel for GT-I9502 which is the phone I am currently using. I don't actually test this build for GT-I9500, so I really need feedback. And please backup your rom before using this.
Features:
Built with OSRC KK 4.4 source and ramdisk, now it should work on many 4.4 roms.
Contains most features from Adam kernel including Wolfson Audio Control. For I9502 which uses yamaha sound chip, Wolfson Audio Control will be hidden automatically since it does not work.
From v10, the kernel is renamed to MaxFour due to wamam's request.
Kernel + Recovery release at one time, recovery based on TWRP with EFS_GSM (for Chinese Duos devices) support.
Compiled with GCC 4.8 toolchain from Google NDK r9c.
Packed in LZMA format to make smaller images.
Native exfat support based on OSRC exfat source code.
UCI script for STweaks and may be others.
Unlocked some hidden CPU frequency: 2.0GHz, 1.9GHz, 1.8GHz, 1.7GHz, 800MHz, 700MHz for big cores; 1.3GHz, 1.2GHz, 400MHz,
300MHz, 200MHz for little cores. Frequencies over stock like 1.7GHz for big cores and 1.3G for little cores are implemented in tc*/overclock version.
Added more STweaks settings which are not included in Adam kernel, including CPU power management, Tools with reboot options, GPU settings, CPU governor.
Android logger is compiled as standanlone module, so user can disable it completely to save power.
Tc/overclock version contains Persus dvfs for GPU with 700MHz overclock, thanks to AndreaLux.
Built-in Seeder entropy generator to provide lag reduction although it is not significant as it was on Gingerbread.
Built-in busybox with auto-installation.
Optimize on ram.
Added several I/O Schedulers including ZEN and ROW.
Built-in dynamic eMMC read ahead
Built-in Asynchronous Fsync
Compiled with compile flag for Cortex-A15 and NEON
Disable KNOX and SELinux when booting, selinux will be set to permissive with the boot command line.
init.d support.
A lot of changes and fixes.
Disabled a lot of rarely used devices support.
PS:
*1. TC means turbocharged, so it is overclock
Change Log:
v15:
Rebuild with GT-I9502 CHN KK Opensource from OSRC.
Upgrade KSM (Kernel Samepage Merging) to uksm (Ultra KSM) which has Super quiet CPU usage, Ultra scan speed and High CPU efficiency.
Support init.d.
Lower CPU frequencies presented in previous versions, voltage options coming soon.
GPU tweak presented in previous versions.
STweaks cueerntly unsupported, coming soon.
mDNIe and Sound Control coming soon.
AOSP support coming soon.
v14:
Upgrade kernel to 3.4.10
Implement AES-ARM and SHA1-ARM crypto algorithm
Rollback selinux related script to v11
v13:
Rebuilt source tree from HNC6 source.
Most features kept
INT, MIF, MEMIO settings removed, these should not be touched
Should be much better than v12
Fixed video bug for AOSP, I think it is fixed
Upgraded AOSP initramfs, may fix the modem/signal problem
Set ro.secure and ro.adb.secure to 0
Camera lag? Less.
Upgraded busybox
v12:
I don't want to talk about it, this version is totally a rubbish
v11:
STweaks: Added Chinese UI, works on Chinese system, when the language is set to other ones, English UI will show. An templete is provided for more translations.
STweaks: Added boost mode in the Misc tab. The boost mode is found when the news of Samsung cheating on benchmark softwares came out. When a benchmark software is detacted running, the boost mode will be on to allow higher temprature and faster CPU scaling. Simply turn on this mode will not provide any visable change, it should be used with CPU, GPU, INT, MIF clock operations.
STweaks: Added control for Internal, Memory Interface and Memory I/O.
STweaks: Added a button to switch the USB mode to Mass Storage Mode, which is classical mode before GingerBread got out dated.
STweaks: Added a CPU wake lock switch.
STweaks: Added instructiuon of Sound Control being not available on models other than I9500.
STweaks: Added instruction of GPU voltage control being not available on non-tc versions.
Kernel: Added a odin mode. Now we can reboot to download mode with "adb reboot odin". The original commands still work.
v10f1:
initial build for XDA users.
Q&A:
I did not reserve a post for this section, so I will put the Q&A here in the OP.
Q: Which package should I use? A: boot is what you need. recovery is just a side product.
Q: Which version I should use? A: Please the "File name instruction" section in the OP, you will find the answer.
Q: Do I need to wipe the data after I flash? A: Well I don't think you need, but due to some report, wiping data can solve certain problems after flashing this kernel. So whatever you like, please backup data before you flash or wipe.
Q: Which rom does this kernel support? A: I can't tell, please refer to the File name instruction section, if you rom is not mentioned there, it is not supported?
Q: Does this support MIUI? A: Official MIUI is based on touchwiz 4.2.2. So please refer to Q2,3,4.
Q: There is no OC in tc version. A: In the init.rc there is a script limiting the CPU frequency to 1.6GHz, so you should use STweaks to unlock it. Please open /sys/devices/system/cpu/cpu0/cpufreq/UV_uV_table, if there is 2000 1900 1800 and 1700, then there is OC, just unlock it.
Q: Some app FC? A: Usually FCs are not due to the kernel, check the rom first, and settings etc, the kernel should be the last reason, cause it just provide the bridge between the system hal and hardware. Report the fc, I will take a look, but I can not say I can fix it.
Q: Battery life? A: It is due to your habit, just like driving a car, a Toyota Prius can use 10L gas if driven by somebody like Michael Schumacher. As my test, due to my habit with non tc version, it is better than stock.
Q: Do I need STweaks to run the kernel? A: The kernel can run without it, but with it you can have more options.
Q: STweaks shows "unextected error"? A: This situation usually happens at the first time STweaks starts, it is OK. Just go on using STweaks.
Q: STweaks FCs. A: Well this sometimes is due to the kernel, sometimes. Here is something you can do: Wipe the STweaks' data, remove /data/.maxfour and /data/.adamax, check the superuser software and give STweaks root access. And yes you need root access. At last, use normal version.
Q: Auto root? A: Use the CWM zip package. And I would take it out soon. Sometimes it breaks root.
Q: Not actually auto-root with v13? A: Yes, v13 will put a wizard like app which will lead you download SuperSU, only when your rom is not rooted.
Q: Conservative governor stock at certain frequency? A: Don't use it, only ondemand governor is optimized for 5410 with big.little cores.
Q: Can you add something? You must do something? Please do something? A: I take advice, but not demand. The reason is simple: I make this kernel due to my interests, not purchase orders. I am not funded for doing this. If the advice is good, I'd take it. If it is just a personal preference, I have to consider it.
Q: Got very low volume of sound? A: Use stweaks, I9500 has wolfson sound control.
Q: Video color is not correct, got blur faces. A: v13 should have this issue fixed.
Q: No internal storage access permission. A: I will make a workaroung later. For now, remount it with rw option through adb.
Q: Random reboot. A: Well, it exists, I admit. I don't know why. I will look for the reason.
Q: After flashing, the phone won't boot. A: Well, I can't guarantee that this kernel works everywhere. And please check if you are using the correct version.
Q: When is your next release? A: I don't know either.
Q: I flashed, it doesn't work. A: Well, it does not work. I don't know why cause it just don't work. I only answer information-rich questions. Questions like this is only a waster of your keyboard, your time and your data traffic. Please at least tell me which version and what rom you are using.
Q: Anything asked above. A: I will keep silence. Other people may insult for this.
Q: Why don't you answer/respond our questions? A: I am a employee, husband, father and son of someone other than XDA and you.

I kept the feature, so it should show up in STweaks on I9500. I am using 9502 which does not have the feature so I can not test it. When I compile for 9500, sound control is enabled.

Well it is hard to say. If you use the normal version, it should be battery friendly. The tc version is overclocked. Due to my 3DMark result, the overclock version maxied out the First and Second stage tests.

Some Proposals
1. Auto Install Stweaks
2. Clearly describe CPU Options which one for big cores and which for little cores
3. Don't lock GPU Frequency at 532MHz as i see by default ... maybe more relaxed 177-532 settings?
4. SELinux is set to Permissive by default ... maybe set as Disabled?
and maybe some very useful Insecure version please?
ro.secure=0
ro.adb.secure=0
(computer translation)

Hi, I already flashed Adam Kernel on my S4. Can I simply flash this Kernel on recovery or do I need to do something else?

If it is in Adam kernel, then it is here. There is a screen tab in STweaks.

Thanks for the link and especially thanks for being the first Dev to include kexec hard boot patch for D851 in his kernel

Heh, I managed to screw up my MultiROM setup.
Fusion LP was a tertiary ROM. I decided to flash this kernel against it. Almost 10 minutes and it never finished flashing. TWRP was also frozen.
On restart none of the ROMs would boot. Trying to reselect Fusion in MultiROM would fail and freeze/lock TWRP. Seems the partition with Fusion got corrupted.
Got tired of pulling the battery so wound up restoring primary ROM and will start over with MultiROM.
Just one of those things probably unrelated to the kernel itself.
I should have at least backed up the secondary ROM. Oh well. ?

Small update to 1.6.5:
14.01.2015/1.6.5
FauxSound support added
Dynamic read ahead
Download within the OP, have fun

I'm using it with Fusion as primary ROM with no problems. But flashing fusion itself takes close to ten minutes to flash, and the progress bar shows nothing until it's done. I was already on fusion, then flashed RIN and Multirom.

Never mind.

Working well with Euphoria.
Thanks for a great AOSP kernel

I changed my primary SkyDragon ROM then reflashed kexec kernel and multirom. Discovered my CM11 was still there (cool) then reflashed Fusion.
Flashed RIN kernel but this time I waited. It took much longer than the ROM install.
But all is good. Fusion seems to be running great with RIN.
Thanks.

Kernel is working great

I've used this Kernel on about 3 different LP ROM's (clean flash) and on each of them, the pull down menu appears and freezes after ending calls whether its being made or receiving them. If you are able to get out of the menu, the pull down no longer works. You must reboot for everything to return to normal...

Nothing says great batterylife except when it tells me 1 day 19 hours and hasnt been on a charger since 8 am

Nice kernel exelent battery and no complains for now ?

Been off charger all day with light use and its still going strong

[KERNEL] Lucid - b3 [STOCK-LP][D802]

Introduction:
Presenting Lucid Kernel, built from LGE v30d sources. This project started as my personal builds and used daily on my device. Although the project status is beta, it is stable to be used as a daily driver. This is my first time sharing my kernel here at XDA. My main goal for this kernel is to improve what the stock kernel provides and more. I currently don't have any plans to add CPU and GPU overclocking, and tons of cpu governors. The kernel is still base on 3.4.0, but with useful patches from the mainline kernel.
Kernel Main Features:
rev_hotplug custom cpu hotplug driver - online cores based on system load and turn cores off when it is idle
Mpdecision off by default, but can still be activated
User voltage control - by @faux123
boeffla_sound by @Lord Boeffla - speaker and headphone volume control.
Tweaked Ondemand Governor with patches from @stratosk
Stock LG ondemand renamed to lg_ondemand
Motorola's Quickwakeup driver - drop the system back into suspend without fully resuming if the wake reason was a special quick wakeup event.
A lot of under the hood improvements
Advanced TCP congestion control
Loads of I/O Schedulers
Init.d support
Lucid Settings - Script to change hotplug, boeffla_sound, and selinux mode. -inspired by @imoseyon 's lkconfig
*This kernel is compatible only on stock LG lollipop rom(30a, 30b, etc.) with BUMPED recovery and KK Bootloader
Installation:
Backup rom or just boot partition if coming from stock
Download and flash via recovery
Reboot :good:
Downloads:
androidfilehost
**Use your favorite kernel apps to control some kernel settings, but I personally use Kernel Adiutor.
For the hotplug and boeffla sound control, run lucid from terminal emulator app.
Code:
1. Type "su"
2. Type "lucid"
3. Enter a number to select options.
eg. Type "2" if you want to change boeffla_sound settings.
4. All settings changed will be applied immediately and will stick on boot

How I can change sound settings? I tried to use Boeffla sound from Play Store but I have FC;(

I haven't tried the boeffla sound app. But to change the values you may use a terminal emulator and type this;
echo "value left value right" > /sys/class/misc/boeffla_sound/speaker_volume
echo "value left value right" > /sys/class/misc/boeffla_sound/headphone_volume
If you want the settings to stick on boot, edit the 07rev script located at /etc/init.d

first tnx...I love stratosk and his work on n4, so I must try your kernel.
You said in op
"Init.d support - creates init.d script upon installation" where is it?
And how to manage the sound and hotplug... I really have no idea.
tnx again

Thanks for the report. Don't use zram, it causes freezes.

Welcome new dev:good: Thanks for support

Tools?
Thank You,:good:
I'm testing the Kernel.
How can change the voltage? Any tool recommended?
Thank You,

Use Kernel Adiutor to change voltage settings.

any relevant bugs we should know. I'm gonna give it a try asap

None so far, just don't enable zram.

I had a nexus 4 and I very love kernel by stratosk . Nice to know that you have a "Tweaked Ondemand Governor with patches from @stratosk" , i will test it now :good::good::good:

so far so good. charging is at 1610 with stock charger.
edit: it messed up my true stereo mod. channels are now unbalanced and no matter what I edit in mixer_paths it stays the same. also tried using the kernel script and lower speaker to balance stereo channels with no sucess.
maybe you can add a value for left/right channel speaker like you can with headphones
edit2: what I found so far. if I use default mixer_path with no mods the kernel scripts works to lower speaker volume. But when using stereo mod mixer_path it ignores kernel script and cant control speaker volume. wouldnt be such a pain if manually editing mixer_path worked like before I installed your kernel. wich also doesnt.
that beeing said Im left with two options. either use a completely unbalanced stereo mod and cant use boeffla settings. or forget about the mod and use boeffla. thing is I realy like this mod
edit3: multicore geelbench is way low, also notice mortal kombat x a bit slow compared to stock kernel.

@remorema could you try this https://www.androidfilehost.com/?fid=23991606952599326
I added back the control for dual channel speaker volume. Test it. If is still doesn't work, could you link me to this stereo mod you're using?
As for the low multi-core geekbench score, I think it may have something to do with how I allocate processes to each core. The tweak I made should give more power savings, but that could be the effect of it. Delete the 07rev script on your init.d before flashing.

I want to give a try to your kernel but first I want to ask you something if its possible, could be possible to add Samsung patch to wifi, etc like Bckernel explained here: https://github.com/simex31/BC_Kernel_LP_STOCK_D802/commit/bcc698ba11d3d55326d853bbc7abc36c4fcac47e and no audio mod?
I get the best wifi @5ghz and [email protected] with that driver, impossible to get with stock.
Thanks!

I will see what I can do about the wifi, but I personally don't have any problems with it. No sound mod is a no go. You can always disable it if you don't wanna use it.

With Wifi is night and day (some people has the same issues like me, maybe is SEA variant the problem), I discovered it with BCkernel and finally I'm not planning to come back to KK because in KK I had problems at 5Ghz only with [email protected], now in LP my phone is ever connected at 433mhz without a single drop, amazing that driver, the only problem I have with BCkernel is the battery drain, now I'm monitoring it with battery widget pro to compare it with stock.
Last note, the issue with wifi is only at 5ghz, on 2.4 it works fine
Another nice plugin to have is screen calibration (kcal).

[kernel][custom][P905] permiisive with init.d support 06/02/2016

hi guys
i finally was able to make a custom kernel with permissive selinux
it seems that my previous roms were having some missing files thats why the kernel did not function well with them
anyway, now it is working properly and so far no problems
i already included the V1 in my rom
so i made a different thread so that it will not be confusing
changelog:
V1: initial release
permissive selinux
V2: 06/02/2016
added init.d support

thanks for your reply
but do not expect much from me
I am just a beginner and wanted a permissive kernel for my device
I will try to add more features but it might take a long time for me to apply them

Great things don't have to be big and bulky bro [emoji4]
I made a post when i first bought the device asked how to make rom deodexed so xposed could be installed and how hard is the process!!
What I'm trying to say is we just wanted the simplest of things [ofc i don't mean it's easy but things that are straight to the point]
Your kernel is just doing that [emoji111]
Opens the door to further mods!
Best of luck bro [emoji106]

Thank you very much for your work, I'll try.

Hello. First, I wanted to thank you for a job well done!
I am using the kernel for something like one and half a month with KOKO ROM and it is *stable*. And I mean stable as hell! - I don't remember even a single random reboot so far! Of course, switching selinux mode with setenforce command is working like a charm, as well as init.d support. Great, great job!
I personally find P905 (and probably other qcom-based variants) *still* the best tablet on the market so far (in my opinion, ofc ).
I am also really *not* interested in custom CM13 developement as stock ROMs has far more Sammy's specific features like *stable* MultiWindow support or S-Pen stuff and even if it is a good experience, I still find using it a waste of device's potential...
That is why I was personally thinking about adding some most popular custom features, like smartmax governor (which I personally find the best option for Snapdragon 800 devices, but opinions may vary ofc...), some custom hotplug driver (MPDecision sucks...) and first of all - enabling CPU overclock/undervolt (I find default maximum horsepower a little too short for handling more advanced tasks on this awesome but resource-hungry QHD screen; also battery-life is not as awesome as it was two years ago...).
So, I wanted to ask you if you are considering further developement of this stock-based kernel?
Also, if you don't have time/will/attitude to continue this great job, I wanted to ask if you have released any sources on github or something which one may sync and continue the developement?
Thank you in advance for the answer.
Best regards.

Thanks for your words
As i said before
I am a beginner so i do not know how to add the features like other governors or enabling volt control
Furthermore i deleted my source but i can remake it because there are small changes that i made and i remember them
I am currently trying to port features from other snapdragon 800 devices kernels like note 3 and note 10.1 2014 edition
But i still get error on compiling
I will prepare the github source then post a link for it

@esgie
i just uploaded the kernel source with ramdisk each in seperate link
hope it is useful to you
i need help with adding synapse support to the kernel
if you know how to do let me know

Thank you.
I have just configured my developement environment.
I will try to proceed with compilation this weekend. I will also check how to implement synapse support
Hear you soon.

Hi.
I want you to know that I am absolute kernel-beginner, too.
Anyway, I have managed to add some basic features to the kernel.
Here you can download img file and test:
https://drive.google.com/folderview?id=0B2TnsPjj6dl4dHNZN3dBb3o1Zlk&usp=sharing
(as of TWRP 3 img files can be flashed directly to boot partition from recovery; P905 only!!!).
Features:
- setenforce working + init.d support (by Teflanzy)
- some custom schedulers (bfq, fiops, sio)
- custom governor (zzmoove with hotplugging support - I recommend to tune it with Kernel Adiutor using profile_number = 5, disable_hotplug = 0 and disabling mpdecision).
So not much at the moment.
It looks like it's hard to automatically cherry-pick a lot of interesting CM12-compatibile commits, as the samsung kernel source differs a lot from the CM one... I failed to add synapse support as for now but I am looking into the issue. Also, I will post and sync my sources not later than tomorrow.
Sorry, my time is limited and experience is not very big.
I am posting a test version here and if there will be enough feedback we may think about creating a separate topic and try to start some constant developement
