I recommend using Trickster CPU Mod in Google Play to set your Governor/Scheduler and Cpu Max/Min and to Control your Voltages. It is a great app
For Best Battery Life I recommend Pegasusq Governor and CFQ or ZEN scheduler. You can READ more about other Governors HERE

Enjoy the Kernel and let me know what you guys think!

Running very smooth without any issue

Hiho, want to try it, is it working on the 8010, too?
Gesendet von meinem GT-N7105 mit Tapatalk 2

Great work.
Is it possible to enable the option to mount the device as external storage in USB ( USB mass storage mode ) rather than as MTP mode ?
Thanks

Awesome im your fan on the s3 rom

It's good to have you here, we need kernel developers, thanks.
The only problem I have with Zeus Kernel is that it's ejecting my extFAT formatted micro SD card.

Flashed ok on my N8010.No problems so far
Good to see you here.

Great work, glad to c the 8013 support. Thanks!
Tapped from an annihilated N10.1

What about - hyper - govermor ?
I have it in my sgs 2 and is working the best for me.
Low states and smooth.

Bro I flash it on N8010 and the kernel is too smooth and great but I have a question that when I benchmark my device i score only 3667 without any power saving mode

Benchmarks mean 0 hahhah.... I like to see the actual feel and performance of the device with the kernel

got this on my 8013 and although it is fast and smooth, i lose wifi. it acts like it is connected, but no traffic will go in or out. if I restore to stock kernel, my internet traffic will be fine.
anything i can do to help find why this is happening? (I am on Hyperdrive ROM - also using the kernel installer on that ROM causes this issue)
everything was installed on a clean wipe

Which tool you recomend to oc kernel?

Will I able to use apps2sd script after flasing this kernel?

[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.
Changelog
v6 (brisk_kk-stock_2015-07-28_15-07-08_64d9234.zip)
Removed more KNOX stuff (--> This fixed some random reboots!)
Finally upgraded to new toolchain: Linaro GCC 4.9.4-2015.06 (Cortex-A15)
Thanks @impactor and @SilviuMik for providing help!
v5
Revert default IO scheduler back to CFQ
Apply changes from new released kernel source (GT-I9195_EUR_KK_Opensource.zip - I9195XXUCOA2)
Apply changes from new released kernel source (GT-I9195_EUR_KK_Opensource.zip - I9195XXUCOE4)
Older versions
v4
Fixed USB-to-PC problems by re-enabling some debugging code
v3
Users reported: USB-to-PC (MTP) doesn't work? (Logfiles appreciated)
Apply changes from Samsungs GT-I9195_EUR_KK_Opensource_Update1.zip
Replace stock Wlan module with kk_2.7_rb1.43
Various kernel config changes:
Disable various unused and debugging features
Re-enable heap randomization
Enable "Optimize very unlikely/likely branches"
Set default IO scheduler to noop
Reduce preemption from "Low-latency desktop" to "Desktop"
Disable Samsungs Rooting Restriction
Added init.d support
v2
Added OTG support (UNTESTED) - Edit: NOT WORKING YET
Removed TIMA
Change to XZ compression
Add BLN support (UNTESTED) - Edit: NOT WORKING YET
v1
Added battery drain patches
Optimize kernel for speed, not size
Preparation for init.d support
Permissive SELinux
Future plans
Add proper Prima WLAN driver - Done!
Add a few more optimizations - Done!
Add init.d - Done!
JellyBean Kernel
The old JellyBean kernel is no longer maintained, but it is stable and its uptime was above 2000 hours on my device. I published it here too, in case someone is happy with their JellyBean ROM and wants this.
Features: BLN, Battery drain patches, kernel config optimized, most debugging code deactivated

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.

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.

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

If it doesn't boot, just restore your boot partition from a backup or re-flash your previous kernel if you had any.

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
Cheers

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.

Frequently Asked Questions -
Q ) I like this kernel, can I be a part and contribute to this project ?
It takes many hours to maintain this kernel, If you are a user then donations are appreciated. If you want to contribute to development then you can create your pull requests on my github or pm me with your patch.

Q ) I flashed this kernel, what next ? How and where do I configure kernel related settings ?
Recommended app is Radon kernel control, it offers very easy to use custom profile based tweaking, you may check post #3 for some tuning tips if you like to tune kernel settings yourself.

Q ) Read mode in miui is not working after flashing this kernel ?
Xiaomi hasn't provided the opensource code for this feature, so read mode is not going to work on custom kernels, but you can try going into display tab of radon kernel control app and make a custom profile with R,G,B(254,234,195) and saturation 40 for very similar experience to miui read mode.

Q ) My fingerprint doesn't work, what to do ?
Kenzo comes with two different sensors, fpc and goodix, all nougat roms have fixed support for both sensors, but if you use miui rom and you have goodix sensor then you might need to flash the patch from post #6196.

Click to collapse
Q ) I flashed this kernel, but I want to return to my stock kernel, how to do that ?
If you read flashing instructions in first post, you will see that I asked you to make backup of boot and system partitions before flashing my kernel, now you can restore that backup and you will have your stock kernel back. In case you didn't take a backup, just dirty flash your rom zip without wiping data and that will restore stock kernel and modules.
Click to expand...
Click to collapse
Q ) How much battery backup does this kernel give ? Will it give me x hours of SOT ?
The battery backup depends a lot on your usage, like screen brightness, wifi, 3g/4g data. Changing your kernel or rom will not make battery backup double. If you are just wifi user, your device can give 9+ hrs screen on time. Heavy 3G, 4G, Bluetooth users shouldn't expect huge battery backup. Regarding battery consumption when display is off, I normally lose 2% battery for about 8-9 hours of standby, but if you you keep wifi and data off in night, then you should get 0-1% drain per night.

Kernel tuning tips -
Cpu -
Governor: Interactive for all kind of users, select battery/balanced/gaming mode while installing according to your need, balanced and gaming modes are totally smooth but battery mode might have little lags.
Users who wish to further push battery backup can try using relaxed cpu governor on small cluster, reducing max frequency of small cluster will also improve battery backup.
By default, I use these min cpu frequencies 691Mhz (small cluster) and 883Mhz(big cluster), there is also 400Mhz option but I don't recommend using that since it saves negligible battery.
Input boost and touch boost should be kept on by balanced/gaming users, battery biased users can consider turning them off.
Memory -
Adaptive lmk should be enabled by all users
Z-RAM 512MB with at least 40 swappiness
Z-RAM will increase battery consumption a little bit
Keep Z-RAM off if you need extra battery backup
IO Scheduler -
FIOPS for good performance and battery
Read ahead at least 512 KB on both internal and external
Screen -
Adjust this yourself, I don't know what you like.
Gpu -
Adreno idler - only battery biased users should keep this on.
Adreno boost - gamers or performance biased users should keep this on.
Misc -
Fsync -Enabled for more stability, disabled for more performance.
Vibration intensity - I use 60, select whatever you like here.
Note - All settings are compatible with Radon kernel control.

I am using RADON Kernel From very first Build and to be honest ,
RADON is Awesome In Performance , Super Smooth and Fully Stable Kernel.

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)
Download
laufersteppenwolf said:
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
Notes:
See 2nd post
GPL:
Kernel sources
Kernel Modules (only for v001 - v003)
Used defconfig
Used build script

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.
Here's link to edited kernel: https://www.upload.ee/files/10238882/kernel-SM-T210-werewolf-Ofast-UV.zip.html

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!
