[KERNEL] [4.4] Werewolf kernel v008 [15/02/2015] SM-T210(R) and T211

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 Modules (only for v001 - v003)
Used defconfig
Used build script

Tweaks and other stuff
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?

When changing the CPU gov, you might want to keep THIS (4.1) or THIS (4.4) in mind
Changelog:

- Added KSM (including deferred timer to save battery)
- Tweaked zRAM

sorry guys, I just found the issue... my last commit breaks the GPU module so it doesn't compile, doesn't get copied over into the zip and so does not get replaced on your system, but the new kernel cannot load the stock module as I used another defconfig name...
Will be fixed ASAP
EDIT: Fixed and uploaded

You can check if there is OC available by installing "No-Frills CPU Control" from the google play store

a question about toolchain
@laufersteppenwolf
hi, i would like to know which toolchain you used to build this kernel, a direct link to it would be helpful.
also, using the supplied defconfig can i make [defconfig] and then make -j# or are there additional things to do?
i build kernel for tab3 10 fine but setting up my system for sm-t210 is proving stubborn. there is another project going on
that i would like to learn from and help with, your help would be appreciated.
thank you for reading.

I do not think so, as I'm using the ramdisk from t210, which most likely isn't compatible with t211, and sure not with 4.4.2

for this build, I used CM's 4.6 toolchain, but that'll change soon
I will also push the build script and modules to github ASAP, so just wait for that, as setting up the modules and stuff isn't the most pleasant thing to do

Werewolf is not playing lol so what your saying is that we will be having cm 11 and aosp all the good stuff soon ?

I've used this kernel for 2 days. I have noticed the screen flickers on the 2nd day and while watching a movie (while plugged in) the tab was battery drained battery was 30% when I started watching. Can others confirm this?
Goodside. Battery life is enhanced and performance is the same. Nice work on this

I was experiencing the exact same flickering myself as well, but on stock kernel
This flickering isn't kernel related, but ROM related. Sammy must have screwed up the auto backlight handling, as it only happens at some certain brightness values

No ir blaster

[Kernel][Stock][CAF][05-06] Redmi Note 3 CAF kernel source

Hi,
I recently bought the redmi note 3 and noticed the lack of kernel support, so I decided to share this with you guys:
https://github.com/daeiron/kenzo_caf_kernel
Its a fully functional buildable kernel for stock MIUI.
Changelog:
05-06-2016
- Merge LA.BR.1.3.2_rb3.28
- Fix camera for some?
28-05-2016
- Enable KSM
- Fix fingerprint on 6.5.26 (xiaomi didn't update their kernel source, so have to use fingerprint hal from 6.5.19)
- Update ramdisk
- Other small stuff
21-05-2016
- Merged to LA.BR.1.3.2_rb3.27
- Merged some patches from ido source drop
15-05-2016
- Tested with 6.5.12
- Full kcal support
- Defauls at boot to 400mhz min freq & bfq scheduler
- Fsync toggle
- State_notifier and state_helper (from neobuddy89)
- Backlight dimmer (from flar2)
- A lot of patches and fixes (see git)
04-05-2016
- Merged to LA.BR.1.3.2_rb3.26
- Upstream patched to 3.10.101
- O3 + makefile optimized
- BFQ, Fiops and SIO
- RGB color support (use custom app like kernel adiutor)
- Other patches (see git)
Limitations:
- No color/contrast/reading mode support, seems they didn't release it as part of the kernel
- In kerneladiutor gpu freq displays at 600mhz, this is just a false reading. Check 'cat /sys/class/kgsl/kgsl-3d0/devfreq/cur_freq' for the real frequency
- If you build the kernel and it won't boot try stock toolchain (https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9) with up to this commit e1a8a48e59638c0d24d2214c2a85046068158a08
To build;
- Clone the repo
- Get yourself a toolchain (I use stock google 4.9 up to commit: e1a8a48e59638c0d24d2214c2a85046068158a08)
- Edit user vars in build/build_kernel.sh
- From kernel root run: sh build/build_kernel.sh
- You end up with a flashable zip file in build/dist/
I am planning on keeping the source up to date with CAF and also sync in the latest patches from kernel.org.
Feel free to fork or use, please mention that you did though.
You can find my flashable zip builds here: https://drive.google.com/open?id=0B7XCSgymRoP0ZjJtSkxuS01kYUk

In oneplus one forum, sultanxda build a CM13.0 with CAF kernel and is pretty smooooooooth

Whoah,
Thank you, I was working on the same thing, this will save me a lot of time.

Yay more dev support, maybe in a month I'll figure out the stuff about building kernels and all that
Thanks for this

Thanks m8 great work

Flashed the kernel, feels snappy but has a big bug, system fails to detect simcard.Tested on both miui and aosp.

Hello, can you explain about the big core limitation ?

What's the difference between this kernel, and Jesse's kernel and other kernels like AEL? There are too many kernels in this thread which are mostly the same, except maybe 1-2 minor differences. That doesn't warrant a new kernel, maybe devs should collaborate with each other and keep minimal number of kernels, having so many of them just causes confusion and bloat, especially when all of them are almost the same in features/functionality. I am seeing people create new kernels with tiny modifications, which is just a waste, rather submit them as patches to kernels that many people already use in this thread, like Jesse's or Superkernel.

Nice,thanks for the explanation.
Great that you keep your source near to stock with no uc/oc etc,i believe it's the only way to keep the good performance,and in combination with stock odexed rom i love it.
What's your opinion about the sabermod toolchain,i remember it was better for the battery but linaro for performance.

[ALL][Kernel][8.1][AOSP] LightningZap! Kernel

Greetings all!
Introducing LightningZap! kernel for the Moto Z2 Force. It is based off Pantheon kernel with some of my own little tweaks and enhancements to improve performance and battery life.
Pantheon features:
Upstream kernel from source
Edits to avoid Safetynet/CTS (If you have root, it will fail signature check inherently without SUhide or Magisk hide)
Disabled CRC check
Disabled dm-verity
Over Clock / Under Clock on CPU Frequencies added:
Little CPU: 175 MHz, 230 MHz, 2035 MHz
Big CPU: 175 MHz, 230 MHz, 2476 MHz; 2592 MHz
Slight undervolt (our device is overvolted compared to other msm8998 devices)
UC GPU (added 180 Mhz step for battery savings when web browsing, low GPU usage)
OC GPU (changed 710 MHz to 750 MHz)
Same Adrenoboost tweaks as the Pixel 2 ElementalX kernel.
Wakelock fixes by Boeffla
Added Zen, FIOPS, BFQ, and SIO IO schedulers
LigthningZap! Features:
Insane readahead tweak: No need to raise readahead cache with a kernel tweaker. With this tweak all partitions are set to their maximum readahead possible and is handle by the io-scheduler. This tweak is best used with FIOPS (set by default), BFQ and SIO schedulers. I haven't ran many tests on other schedulers.
LightningZap! sysctl tweaks: Adjust values for kernel system controls for better performance and battery life.
Lionheart governor added: This is the recommended governor for LightningZap! kernels. I have set the dbs_tuners_ins.sampling_rate and min_sampling_rate to 100 (lowest value)so the end user can adjust the values in their favourite kernel tweaker add to suit their needs. It's very simple, when setting the sampling rates, a high number will improve battery life but performance will take a slight hit, and a lower number will increase performance but battery life will take a small hit. Values for these range between 100-1000. This governor is not set by default, but can be set with you favourite kernel tweaking app
Aroma Installer: Same options as in Pantheon kernel for now. More to come as I work them in.
Compiled with Linaro 4.9 only (no clang here)
See second post for fixes, improvements, changelogs, and downloads
Source code: LightningZap! kernel for nash
Flashing Instrcutions:
Device must be rooted with custom recovery (TWRP)
Place LightningZap! kernel for nash on sdcard
Reboot to recovery and flash .zip
Follow on screen prompts
Re-flash root (Magisk)
Reboot, wait 15 minutes, and enjoy
For further adjustments, I recommend Kernel Toolkit
I wasn't going to post this kernel, but since there is very little other support and options going on with this phone, I changed my mind.

He used my LOS base. Will work on LOS, but not other AOSP ROMs. @thomas.raines, you might want to start merging from o8x-caf. Your kernel is at 4.4.132 latest stable is 4.4.138. (Just going off your git). It might make WiFi break with LOS, but @npjohnson stated they will be merging those caf commits in the very near future where you don't need two forks anymore.
Thanks for the USB tethering fix as well. Merged into mine today and sending a release shortly.
Edit: oh, yeah, verity bypass isn't in my kernel anymore, so if you want to add it, you might want to pick it from EX, Franco, or Kirisakura kernels. Didn't see the point, so when I rebased, I didn't pick it in.

I'm using your AOSP branch (I thought)... It's working on AOSiP flawlessly. Thanks for the heads up on the verity bypass. I'm actually working on that now, but not sure if I'm going to or not... Glad I could help with the USB thethering...

If it comes off my source, Motomods should work.

Removed the stale branch. My source just got 4.4.139 merged into it. I use Nathan Chancellor's msm-4.4 tree if you ever don't want to wait for jbats or I to push the Linux-stable commits.

Just merged the 08x-caf branch... Thanks

So if flashed on stock and it broke my Wifi how do I go about fixing it? This Moto Z2 force is like starting all over. I thaught i was good at this once? Other than no WiFi the kernel works great. Thanks for the development this phone needs all it can get.

I got a bootloop. Any advice?
I'm on Lineage OS 15.1-20181106.

Unless OP updated for Treble (mounting /vendor instead of /oem) this won't work on Treble. Any LOS built after August is Treble enabled. Try with DU official.

[Kernel] [EAS] [CAF PIE BASED] [GCC8] LoverOriented Kernel

Why LoverOriented?
There are many programming language which are object-oriented. In Chinese, the pronunciation of "object" is same as "lover", which is more than just a pun. And a tease that a programmer with a girlfriend .
Note: This is not a kernel with a lot of "useless" features, I will only keep those features that really help for our devices. So you just need flash and enjoy, in general, you don't need to use the kernel controll app to care about the configuration of kernel.
Features:
Based on latest caf pie tag with latest upstream merged
Really much optimized to boost battery and performance for your phone
Full EAS supported with sultan's boost
Build with custom gcc-8.2.1 with cpu-specific optimization
QC3.0 Fast charging (Depending on thermal of your rom)
Doubletap2wake
KCAL Advanced color control
Sound control
Underclock CPU/GPU(CPU mix 175mhz and GPU mix 171mhz)
Undervoltage CPU
Wakelock blocker(already disabled some useless by default)
Adjust or disable vibration
Maple i/o schedulers
Westwood tcp congestion algorithm with many tcp fix from upsteam
Zram support with latest upstream lz4 compression algorithm
NTFS r/w, CIFS and NFS support
Performance and power optimizations
FS fsync toggle on/off
sultan's simple android lmk
File system optimization
Improved sound quality, forced use of high resolution to output
Disabled many debug which are useless for users and keep it clean
AND MUCH MORE

Thanks. I must have been blind...

Hello, can you add interactive original scheduling back to the kernel? If so, could you please send me a copy? Thank you. And in the process of using the ROM you compiled, the frequency of this kernel is 175mhz, but the frequency of ROM kernel is 300mhz. I hope you to change it to 175mhz,

The Kernel works with Pie ROMs only?

A Bug:Can't charge on shutdown

Nice kernel and thanks
Worked with 7.1.1 miui, but wifi does not working

Anyone using this kernel on pe unofficial?
