[KERNEL][I9195][Stock JB/KK] brisK v6

brisK Kernel​
brisK is a KitKat kernel for stock-based ROMs for the Samsung Galaxy S4 mini LTE (GT-I9195).
It aims to be faster and more a bit more battery-friendly than the stock kernel, while retaining its stability.
To prevent bloat I will only apply useful features like BLN. Adding 10 random governors and schedulers is not useful in my eyes, and is also not the goal of this kernel.
Goals
Stability: The original Samsung kernel is stable, so let's not go too far away from it. This kernel doesn't need bleeding edge code - it just works(TM).
Efficiency: Less power consumption by faster computation.
Battery: A battery drain patch is included, which is not in Samsungs original code.
Speed: Minor changes, for example: Trade some screen smoothness for less kernel overhead. Should not be noticeable, though. Also lowers power consumption slightly.

Installing
To flash any of these zip-files, you need to install a custom recovery on your phone. (For example: http://forum.xda-developers.com/showthread.php?t=2364980 )
Put zip file on your phone or on its microSD
Boot into recovery: Hold "Volume UP", "Home Button", and "Power Button" when it is off or rebooting
MAKE A FULL BACKUP BY USING THE BACKUP-MENU
Select "Install from zip" or something similar
Navigate to your zip file, select it, and flash it
Reboot your phone
Uninstalling
If you want to go back to Samsungs stock kernel or flash another kernel, you need to install "samsung_jb.zip" or "samsung_kk.zip" first.
brisK uses custom kernel modules. When you run on brisK and then directly install another custom kernel which has no custom modules, you will probably experience issues with WLAN and other stuff. To solve this, flash "samsung_jb.zip" or "samsung_kk.zip" (which flashes the stock modules), and THEN flash whatever custom kernel you want. - Of course you do NOT need to do this if you update to a newer version of brisK.

thank !
GREAT !!!
but for governors and schedulers , i agree with you in half ... but "few" of them are very useful !
what do you think about the recent "zen" ...or "row" ( by default in all customs like cyanogenmod ) ?
for you ,what are the "best" (more adapted ) for better compromise in performance/baterry save ?
why you don't add just 1 or 2 among the best of ones ?

Now running on brisK

I agree that some governors might actually improve performance, but there isn't much information available, some people say governor A is better, some say B is best...
But also: Kernel goal nr. 1 is stability, and ondemand is well tested. That's why I probably won't add any new governor before testing them a lot.
Can you suggest any governors? And do you have proof or URLs why they are better? Thanks!
If you want more features, more governors, etc, f4k will probably release a stock kernel soon. So keep an eye out for that!

Zen: I don't know what this does different than other schedulers, I have to read about this first.
I considered "row" when I had an Evo 3D, but I didn't notice a difference between "noop" and "row" in normal daily usage, so I'm not sure yet if I will include it or not - needs more testing.

Same thinking as me ...
ondemand for CPU Gov / No-op for I/O sched , they work great and don`t cause problems

Yes, my experience too!
Although, when I copy big files with "noop", android freezes for the duration of the copy process. That's the nature of "noop", but "row" might actually fix that. But then again: I rarely need to copy big files, so "noop" is okay for now.

NOOP hangs in general when the read/write task becomes too intensive. Consider CFQ if you're going to do a bit write operation, else ROW is better. That my two cent when I tried on my S3 with Boffela kernel.
PS. ZEN hangs even worse than NOOP.

thank for your work...
is your kernel working with old knox-free bootloaders like Silviumik's kernel?
thanks

battery life compared with carbon 4.4.4 ? PLEASE

For now i think no, because he did not remove Knox reference from source, i could be wrong tho !

I just released a new version!
A lot people asked for OTG, so here you go! I added OTG and BLN (untested!!!), thanks to junkyDE!
The highest kernel goal is stability, but I don't have time to test these features right now - maybe I can do one quick emergency fix tomorrow if something breaks, but after that I will probably not respond for 2 weeks or more.
So, have fun and enjoy!
brisK v2
Added OTG support (UNTESTED)
Removed TIMA
Change to XZ compression
Add BLN support (UNTESTED)

I removed TIMA in brisK v2, so.... it -should- work now right?
If it doesn't boot, just restore your boot partition from a backup or re-flash your previous kernel if you had any.

Thanks a lot for your input! Now I know I don't need to consider ZEN, and will stay with NOOP, and aim for ROW when I have time to add it.

I9192?

SilviuMik made a 9192 kernel:
http://forum.xda-developers.com/showthread.php?t=2592308

[KERNEL][13/08/16][CM][UT]KTO Kenzo Kernel[Stable]V1.3

By flashing this kernel, you accept your fate.
This is my personal project, because of the lack of any custom kernels that had the features I want. So let me introduce myself. First of all, I'm noob in kernel developing. I've been using many great kernels on my Desire HD and Nexus 4. I've been hoping for such a kernel for our devices for the last 3 months but as it seems, more time is spent on cooking roms instead of kernel development. So well, here we are. I've been working on that for the last two weeks so, this is probably stable, but the alpha tag will stay at least till more people confirm that it works on different roms.
Initial kernel features:
Compiled with stock toolchain (for now)
Disabled software CRC + option to turn it on
Disabled fsync + option to turn it on
Fixes for high cpu load times, which can cause some governors to not work as they should
Disabled zram - with 2/3 GB of ram in our devices, we don't really need that.
Added Kernel Samepage Merging - off by default
Added FIOPS and SIO i/o schedulers
Added ZZmove and ElementalX cpu governors
Added toggle for Touch boost - you can now turn that off.
Added full KCAL display settings support.
Other optimizations
Safe roms confirmed to be working with the kernel
Official AICP - tested by me
Official RR - tested by @nexuspur (Huge thanks to you mate!)
AOSP+RRO - tested by @sheshuvadrevu
Official AOKP - tested by @DarkHero140
CM by banmeifyouwant - tested by @CodeBreaker13
DU - tested by @Windslash31 and @DarkHero140
Not safe roms
Mokee - giving bootloops
Santosh's CM13 - giving bootloops.
Flashing Instructions
Flash only if you're using CM based roms that follows the official CM device/kernel/proprietary repos! That kernel IS NOT FOR MIUI or AOSP Rom
Make backup of boot in twrp
Flash the kernel zip and reboot
About feature requests
I'm sure that many of you will ask for feature A B C. Please don't mention wake gestures as dt2w and swipe2wake, because I will NOT add them. To rework all the gestures for that is a massive job. Even if it was an easy commit to cherry-pick, I still wont add it, because this is battery drainer. We have FP sensor so use it, or wake the device with the power/volume buttons.
Everything else as request is welcomed, but not guaranteed that it will get in the kernel. Remember this is my project and I'll be adding only features that I find useful.

Kernel Special Features:
Version Information
Status: Stable
Current Stable Version: 1.0
Stable Release Date: 2016-07-11
Created 2016-07-10
Last Updated 2016-07-11

Changelogs:
KTO Stable 1.0
Added adreno idler driver for lowering the GPU power usage
Added the following tcp congestion algorithms: veno, reno, bic, westwood, highspeed, hybla, htcp, vegas, scalable, lp, yeah, illinois (Cubic as default)
Some optimizations here and there
KTO Stable 1.1
Added Alucard and Darkness governors. They both perform well. I'm using Alucard which is tuned a bit.
Some vibration tunes
Changed the toolchain from google's default to @DespairFactor UberToolchain 4.9. Sadly I get bootloops after Miui logo with 5.X so can't even get a logcat. Will debug that in the future.
KTO Stable 1.2
Unlocked 1440MHz for a53 and 1804MHz for a72 cores freqs, just like on Xiaomi's original kernel. (Thanks for the tip @Umang96)
QC 2.0 is added - Haven't seen any change with the stock charger. Temperature is normal. Charging around 1600 mah.
Alucard - tuned one more time for the new freqs.
KTO Stable 1.3
Synched with latest CM sources, so we have new led driver and many bugfixes.
Added hardware CRC32 accelerator
Fixed -2/50% bug for people that had if before
Fixed the sudden 2% battery drop bug
Added power suspend driver
Remove the so called "qc 2.0" fast charging. To be fair, I haven't seen any improvement in charging time, but the batter was going hot. Charge your device overnight.
Some entropy tuning
Other patches for better memory speeds

Let me ask this.. This is from what I guess is for TW and CM roms? Also what is the N910F-N910G, are they international phones? I saw a few roms and was woundering how easy it would be to port them to verizon.. I will download and flash this kernel.. Thanks.

Yes they are international variants of our device. But as far as rom porting, thats beyond what I know how to do right now so I dont want to steer you in the wrong direction with how to do it.

Sweep2Sleep only works right to left not left to right

Running on Paul Rizz, works great, I love this kernel

I'm running Modest ROM and Oscars kernel, I tried xposed but can't get it to work. I was hopping by flashing this kernel that I could use xposed, and maybe battery life it be just a little better.

I can't get Synapse to work with this kernel -- it keeps saying "No UCI support detected". According to the main thread, this means a bad flash. I've reflashed it with the same results.
Any ideas?

CM 13 bootloops with this kernel.

Running smooth for me.

Have you been able to get the ZL Emotion Kernel working properly? I'd love to make the switch from Oscar to have my ZL show proper stats, but I saw a couple of your posts on the main thread that seemed to indicate that it still doesn't show the correct battery stats or have all of the Governors listed in the OP.

Thanks for the kernel!! I'm testing it now and it feels good so far

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... .

Anyway to flash back to Stock Kernel?

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.

Ok nice I will try it then. By the way it is better to use ext4 for other partitions than /data and /cache.

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.

Recompiled & Optimized Werewolf Kernel [SM-T211]

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?

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.

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!
