This is my first i9506 Kernel. It is based off the original Samsung lollipop sourcedrop and has some modifications i consider wise compared to pure stock. The aim is set on maximizing the performance and battery life by introducing as few changes as possible to the codebase but as many as necessary. Features that enhance the user experience (e.g Faux Sound) are also included. If you want a specific feature to be included and you think more people would like it, please feel free to ask me to include it.
*THIS PROJECT HAS BEEN DISCONTINUED, feel free to clone the sources*
Supported Roms:
XXUDOA6, XXUDOB5, XXUDOC5, XXUDOD3, XXUDOF2
[ROM][i9506][LP][eXtremely Tweaked][De-bloated]
Darklord S6 Port v3 *needs DOF2 Baseband*
If you want a specific, non-AOSP-based ROM supported, please write it in this thread
If you are a ROM developer you are free to ship this kernel with your ROM, just leave proper credit
Features:
SELinux "Permissive"
SuperSU 2.46 by Chainfire included and automatically installed
Busybox
Init.d Support with Initscript stdout logging and adjustable logsize
KNOX Removal on Install
Arteractive CPU Governor
Snapdragon Optimized memutils
Based on Samsung I9506 XXUDOE2 Sourcedrop
Faux Sound 3.6
Intelli Plug 3.8
Touchboost
eMMC and SDCard read_ahead 2048 KB
Idle GPU Frequency 200 MHz for Battery
Fiops IO Scheduler
FSTRIM Init.d Script. This trims /system /data and /cache at boot.
Built with Linaro GCC 4.9.3/2014.11
Support for XBOX360 Controller with LED and Rumble
Regarding init.d:
The logfile is located at /data/initdlog. The logfile contains date and time, so you can relate the entries with the current boot. What is also logged is which scripts from /etc/init.d were executed and their stdout. If you want an initdscript to write extra stuff to this logfile just add "echo" to your scripts.
[*]You can also specify a maximum log size for /data/initdlog. For this, you need to edit /system/bin/sysinit. The default is 8KB. When the logfile gets too big, it gets deleted and is then recreated at boot.

How to Install:
Just flash the zip with CWM or TWRP. Currently this has only been tested with TWRP 2.8.5.0 and TWRP 2.8.7.0!
After install, SuperSU will ask you to update the su-binaries. Just hit "normal" install, reboot and you are good to go.
If you have WiFi-Issues, please make sure that your Baseband Version is the same as your ROM Version!

Created 2015-03-15
Last Updated 2015-09-10
Source Code:
This project is now hosted on GitHub
The whole toolchain used for building aswell as my zip packaging scripts are available there too
You will even find the latest unmodified stock samsung kernel source there as a branch of my kernel if you dont like dealing with the slow-as-hell samsung servers.
My GitHub Profile
For building the kernel and using the toolchain you need the following software installed:
On 64 bit Linux multilib is required:
lib32-glibc
lib32-gcc-libs
On 32 bit Linux:
glibc
gcc-libs
As prerequisites for The linaro toolchain:
arm-none-eabi-gcc
arm-none-eabi-binutils
General stuff:
gcc
lzop
ncurses
zip
cpio

Work great for me. Much faster than stock kernel. I like
No xposed for TW roms yet.
Amazing!!
Thank you very much for your time and effort.
It works perfect and Viper4 sounds again!!!!
Thank you.
Thanks! Fast and stable!!!
Feature list looks impressive! Will this work with the official Cyanogenmod rom for the i9506?

First unofficial kernel for Galaxy Tab 3 Marvell PXA988, reported works on T210 and T210R variant (T210 version) and T211 (T211 version)
Kernel source: https://github.com/kumajaya/android_kernel_samsung_lt02
Kernel modules source: https://github.com/kumajaya/android_kernel_samsung_lt02_modules
Features:
Based on my kernel commits and modules commits:
Open source exFAT filesystem driver from Samsung OSRC
Configurable touchscreen orientation, so we can use this kernel as touch based recovery kernel
Override 1MB ramdisk size limitation + xz compressed ramdisk. CWM recovery need > 2MB ramdisk, no blackhawk = no CWM/CWM based recovery
Zram support. Update LZO compression library to upstream version, optimized for arm processor
Linaro gcc compiler. Update Marvell P4JB CPU init routines for linaro
Hardcoded ION carveout memory. Old version bootloader will boot this kernel without blank pop up bug!
Using the latest T210R MJ1 GPU, WiFi, bluetooth, and T211 MI3 telephony drivers. This kernel always bring the appropriate kernel modules inside /system/lib/modules to prevent kernel modules incompatibility issue
Single source for all T21x variants, different kernel config, different flashable zip for T211
Integrated self compiled busybox, fstrim applet included for a lag fix
Auto root, no need to flash any root solution
Init scripts support (/system/etc/init.d, /data/local/userinit.d, and /data/local/userinit.sh)
Kernel module loader template /system/etc/init.d/02modules
Post boot template /system/etc/init.post_boot.sh
Zram manager, over "adb shell" or Terminal Emulator:
Code:
su
setprop persist.service.zram 25
to set 25% memory size zram, persistent.
Code:
su
setprop persist.service.zram 0
to disable zram. Needs reboot.

Flashed 1.2 and System Tuner reports that both cores are maxed out (1.2ghz) and do not scale back down. I gave it a few minutes after restart and they remained maxed out. (Wifi off, nothing syncing).
Flashed back to 1.1 and everything looks normal again.
Not sure how reliable System Tuner is.
EDIT: Nevermind...flashed 1.2 again (wiped cache and dalvik) and all is well. Both cores scaling properly now.

I'm seeing similar behavior.
does system tuner allow for adjusting settings? i'm using kernel tuner - http://forum.xda-developers.com/showthread.php?t=1719934
& it was showing the 'min' value for both cores was set to 1205Mhz, the same as the max.
i've backed it down to 312Mhz on both cores & all seems to be good.

I don't think System Tuner does a very good job reporting dual-core devices, but I haven't found a better app yet (still looking).

running great. Thanks man..
Looks like the IR is not working. I'm going to flash back to stock to make sure it works correctly with that.
Edit: IR blaster works on stock but not on this kernel (v1.2).
Let me know if you need any files from me to get a possible fix.
Does this kernel have more cpu governor or/and I/O governor?
EDIT: Oh nevermind i checked your source.

The rom @civato made does not come with this kernel. You will not be able to use Synapse until you flash this kernel.
I guess this is only working for P900, not P905?

It is stated that way in the OP.
Civato,
Thanks for this great kernel and hard work! Installed on my rooted P900 and works so far great. AND it fixes the BT issue with the Logitech keyboard.
Yes. Civato amazing work, logitech keyboard working great with this!
Yes this kernel fix the Bluetooth Problem.
Hi Guys,
Can someone help with a quick install steps list for newbie like me from stock tablet?
I've downloaded both the kernel and source file and put them in the SD card.
I've started under custom recovery mode and selected update from external storage in the menu, and run it for both file but I've got nothing different afterwards and still the famous Bluetooth issue.
Thanks in advance

When you say "Clean start from Latest Samsung source" do you mean the latest 5.0.2 rom P900UEU1COH2_P900XAR1COH2_XAR? Or is this something else entirely? Thank you.

No you are talking about a rom release, This is a kernel release, those sources you download from a other place.
With custom Kernel I had screen flickering under huge CPU load and low battery, so switched back to custom kernel.

Civato can this be dirty flashed over 1.5
Now I'm on 1.8
Everything seems fine. No flickering so far, but with nearly 90% battery. [emoji106]
I will send more feedback this evening with less battery
Nice work! Special THX for fast fix!

What do you mean by screen flickering? Does the screen actually shut down and (then) you have to (manually) switch it on?
Also since custom kernel created the issue to you, why did you "switch back to custom kernel"?

No, I don't must switch on manually.
The screen flickers an half second to black and comes back from self -> it flickers
With stock Kernel and also with 1.8 Kernel the problem is gone.
Tested yesterday with 15% Accu. Everything is fine now. [emoji106]
Edit: I mean "switching back to stiock Kernel" sry for irritations [emoji6]

X3a40 and X3c50/70 modems are different.
You can use each other's ROM as long as you use the correct modem firmware (NON-HLOS.bin file). I flashed S217 from X3a40 in my X3c50 but first replacing NON-HLOS.bin file with the one taken from X3c50 stock ROM.
If you flash the wrong NON-HLOS.bin file all wireless functionality is lost. No SIM recognition, no cell coverage, no WiFi, no bluetooth.
Whatever you do make sure you first backup you QCN.

But it's a kernel, it doesn't flash modem firmware and all that. @vibex3user , check if Wi-Fi is working in 1.1.0, if not, flash the custom ROM again and get me /system/lib/modules folder .

report
After rebooting the device the subscription to the Wi-Fi network get lost, means I have to reenter the password after every reboot. I don't know if it's the kernel like it is or because I changed the TCP congestion fromm cubic to highspeed. I don't have any experience with this feature. I could change back to cubic and check if the network subscription sticks... .

Would a boot.img backup in this case suffice? I haven't flashed the kernel yet but a boot image backup would contain the old kernel as well. The question is mostly if there are any other modifications that are being done.

If you don't have the zip file, I would say, you could restore the boot and system partition from your backup, this should bring back the backuped kernel.

All other partitions are simply not supported
Kernel works great so far. No issues and performance feels good.
What's the best way to switch between SELinux permissive and enforcing on this kernel should one want to experiment with that? Some solutions don't seem to like KNOX but it should be disabled on the kernel, too, right? I'm still struggling to get Magisk Hide working so I'm feeling experimentative.
Hi!
I was looking through @laufersteppenwolf's kernel source and noticed it was compiled with -Os flag and an old toolchain. I decided to recompile it with graphite and -Ofast flags (the highest optimization level) and with a newer toolchain. Though the later failed (All builds with 4.9+ toolchains failed to boot on this device ) it still feels faster than the original build. I have also disabled some debugging options so that the kernel would fit in the boot partition in addition to some performance gain.
Features
Compiled with graphite and -Ofast flags (linaro 4.7.4)
Undervolted Wi-Fi, Vibration, LCD and Touch by 10% (Not sure if they're effective or not)
Disabled some debugging options
Added a lower charging current level (1700mA) to fast charge options (To reduce heating during charge but must be selected by user, Default is 1800)

Hey guys
As you already might have read in either the CM11 dev thread or the Q&A section, I am working on a custom kernel for our T210(R) and T211. It's still in a pretty early stage, but the current build is fully stable, so I thought why not share it
As I'm pretty new to this community, a few words about myself: My (only) device I have been working on is the LG Optimus 4x HD, for which I also made a custom kernel (also named werewolf kernel, who would have thought of that ). Me and 2 other fellow RDs were able to "switch" many blobs with the ones from grouper, which fixed many, many issues we were facing in 4.4 with the stock 4.1 blobs. I am the official maintainer of namelessROM and vanir for the 4x HD, and am also compiling GummyROM, LegoROM, unofficial CM 11 (using grouper blobs) and SlimKat for the 4x HD on a nightly base. And as soon as we have a proper device tree for our tab, I'm sure I can port the Tab3 to all those ROMs
Now, enough chit chatting, let's talk about the kernel
It's based on @ketut.kumajaya's blackhawk kernel (thanks again, mate ) From v004 on we are based on official KitKat sources, with some additions such as:
Features:
Various network tweaks
Entropy tweaks
I/O speed improvements
cortex a9 and neon omtimizations
Added frandom
Tweaked vm dirty ratios
Dynamic read-ahead values
Added I/O schedulers: ROW, SIO, BFQ, FIOPS, V(R)
Optimized AES and SHA1 routines
Added CPU governors: Lionheart, Adaptive, Intellidemand, Hotplug, Hyper
Reduced RAM usage from logger
Updated lowmemkiller
Overclocked to 1.420 GHz by default
Disabled vsync for better 2D performance
Overclocked GPU up to 624MHz (default 416MHz)
Custom user voltage control (CPU)
Undervolted by default (-25mV)
S2W and DT2W (WIP)
Fast Charging
KSM
Bugs:
You tell me!
Installation:
Download the kernel from HERE
Reboot into recovery (recommended to make a nandroid)
Flash the kernel zip
Recommended to wipe /cache
Reboot and enjoy!
And remember to remove phservice if you want to change some CPU/GPU settings yourself

Tweaking Guide
laufersteppenwolf said:
Since v002, we have an updated lowmemorykiller. It behaves a bit snappier than the old one, also with the default minfree values. However, in case you like to tweak your device a bit to make it even more snappy (like me ), I tweaked the minfree values a bit to slightly increase the free RAM without really affecting the multitasking experience. The script can be found in the attachment. All you need to do is to extract the script and place it in your /system/etc/init.d/ folder and that's it. The values will be automatically set on boot.
UV interface
The min possible voltage is 1000mV for now, and the max one is 1400mV. If you want me to lower the min voltage, please let me know.
Also, please note, that the voltage has to be changed in 12.5mV steps. If you apply for example 1110mV, it will be rounded down to 1100mV.
Fast Charge interface
The main interface is inside /sys/kernel/fast_charge/*
/sys/kernel/fast_charge/force_fast_charge (rw)
0 - disabled (default)
1 - use custom mA configured through the sysfs interface (see below)
/sys/kernel/fast_charge/ac_charge_level (rw)
rate at which to charge when on AC (1.8A to 2.3A)
/sys/kernel/fast_charge/usb_charge_level (rw)
rate at which to charge when on USB (0.5A to 1.0A)
/sys/kernel/fast_charge/failsafe (rw)
0 - disabled - allow anything up to 2.3A to be used as AC / USB custom current (USE WITH CAUTION!)
1 - enabled - behaviour as described above (default)
/sys/kernel/fast_charge/version (ro)
display fast charge version information
New kmsg layout
From v008 onwards the kmsg looks a tiny bit different. Instead of displaying the time since boot, it logs the actual time and date.
Now, you may ask yourself: "does that any good?" Sure it does. When you encounter an issue and grab a log, you can send it my way saying "the issue happened at 15:35". It is way harder to find out the exact time (in seconds) since the device booted, right?

Great! Did you upload your source?
I had been working on it to compile with GCC 8, but haven't got enough time to complete the cherry picks

It's on github but I didn't link to it cause it's messy. BTW There is no source code change aside from makefile and defconfig.
BTW, that link is blocked in India, can you upload it somewhere else? and also, cna you provide link to your source?

Sorry for late reply, I'm busy with my thesis these days. I've attached the file to the post. Will send you a link to the source (GitHub) in your PV.
Great! Finally something new for T211/0. Love to see some movement here.
Tried installing on a T210 with TRWP but get an error message. Anyone any ideas?
Tried to attach the error but it won't let me... Error talks about asset failed getprop ro.product.device == lt023g etc
@Samw13
SM-T210 = lt02 wifi Tab
SM- T211 = lt02_3g Tab
So, i have deleted requirement in update-script file and kernel seems to work correctly on t210.
Here's link to edited kernel: https://www.upload.ee/files/10238882/kernel-SM-T210-werewolf-Ofast-UV.zip.html

Is it fully stable on SM-T211??. Is it the final version??
Hi,
@mat1371,
@lol28
Thank you for the kernel for T210R. Stable, overclocked to 1.42Ghz. I have an issue with the settings I make, they don't stick after reboot. I used kernel adiutor, EX kernel manager, Performance tweaker. I have busybox installed.
I've flashed Powerdaemon.disable.zip from Gr8nole, still the same.
Edit:
I've found Gr8nole's suggestion about deleting /system/bin/phservice. I deleted the file, rebooted, changed to governor to lionheart. It seemed to keep the settings.
Thanks!
