[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

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

About Fast hotplug
Motivation
I wasn't convinced by show-p's msm_mpdecision nor faux123's intelli_plug ( I don't even talk about qcom mpdecision ). I also wanted to start working on a bigger programming project to learn more about kernel developing so I decided to write my own hotplug.
Main features
I tried to make fast hotplug the lightest possible, so that it consumes the less resources possible when it is not needed (mainly at idle). One of the second goals was to make it customizable.
How to use
Deactivate qcom mpdecision (Pimp my Z1 will do this automatically when you choose fast hotplug)
Activate fast_hotplug
Code:
adb shell "echo 1 > /sys/module/fast_hotplug/parameters/fast_hotplug_enabled"
Tune it to your liking
How to configure
Unfortunately, there isn't yet any user friendly application to configure fast hotplug. The only way to configure it is to manually edit the module files with adb or a file editor.
I modified Pimp my Z1 to be compatible with fast hotplug. You can find the modified version at post 12
You can also find all the parameters at
Code:
/sys/module/fast_hotplug/parameters/
and edit them with adb command
Code:
adb shell "echo [COLOR="Navy"]<value>[/COLOR] > /sys/module/fast_hotplug/parameters/[COLOR="Navy"]<variable_name>[/COLOR]"
You can configure the following parameters :
fast_hotplug_enabled : 0 for disabled, 1 for enabled
boost_duration : Duration of boost in ms when screen is touched
threshold_to_boost : Instead of automatically pluging in cores on touch, fast hotplug checks that the load is above this threshold. This avoid cores coming online when reading file or website.
max_cpu_on : Maximum number of online cpu when screen is on
min_cpu_on : Minimum number of online cpu when screen is on
idle_threshold : Threshold under which fast_hotplug will remain almost idle and won't perform any check. This applies when only 1 core is online
plug_in_core_X_threshold : with X between 1 and 3. This is the threshold to plug in coreX.
plug_in_core_X_delay : This is the number of fast_hotplug cycles (see refresh_rate) to skip before pluging in coreX.
plug_out_core_X_threshold : Like plug_in_core_X_threshold but to plug out.
plug_out_core_X_delay
refresh_rate : Time in ms between fast hotplugs checks
screen_off_singlecore : 1 for activated, 0 for deactivated; Allows only one core to be online when screen is off.
If you are using linux, you can easily change the configuration with this small program : https://github.com/pec0ra/fast_hotplug_controller
You will probably want to create init.d script to make your configuration stay after reboot. If enough users want it, I can create an example of script.
Bugs / stability
Due to some conflicts with qcom mpdecision, it is possible that you encounter some bugs / reboots when both are enabled.
Configuration doesn't stick after reboots
Help needed
If you are a java developer (or want to learn ) and want to help in developing an app (or editing an already existing one) to control the hotplug, please send me a pm
Please tell me your impression, your custom configuration and / or your recommendation so that I can make it better in future releases.

Good luck.
Will try as soon as I can. :good:

Welcome! :good:

Regarding this, there is already an app out there that is FOSS, licensed under the GPLv2 license, looks sexy and should be easy to modify. It's called Pimp My Z1, I think it offers pretty much everything you want.
Other than that, cool that you're developing something new, I'll give it a shot!
Edit:
You may want to disable Sony's RIC it prevents you from writing to /system. This should help you.

I can't seen to get notification breath effect,i didn't do the mpdecision step,so could this make the diference?

Is this kernel compatible with franco kernel apps?

I'll see if I can do something with this app when I have more time (I've never made any android app).
Disabling ric is a good idea I'll do this for next version.

No, mpdecision won't affect it. Have you tried it on YadliKernel ? Did it work for all the notifications ? It seems like on abricot kernel they work for most of the notifications but not for sms.

It is probably compatible (I didn't tried it) but you will probably not be able to change most of the configurations since they are not implemented in my kernel. Some configuration from my kernel (like fast hotplug) are also not implemented in the app so you can't change them from there.

There's no printing in the mod I think so dmesg would be useless. I'll try again with WhatsApp. Have you tried it on other kernels? Was it working ?
Edit : ok, maybe there is an error... In this case dmesg could be useful. If you have time you can send it, yes.
And I reconfirm that it works for telegram

Hey, can someone show us the notification mod?

Pimp my Z1
As @B1nny suggested, I tried editing Pimp my Z1 to add fast hotplug support. Everything seems to work and I even added some tweaks for a better support for our Z2 ( some default values were not really compatible with our device ). There are probably bugs for configurations other than fast hotplug. If I have time, I will fix them but for now, please use another app to set your frequencies / governors / voltage or live with the bugs. If you have questions about the app, you could also take a look at the official thread to see if it is already there or maybe just to give the dev a thanks.
I'll probably make a pull request to @Androguide.fr with the changes but until then you can use my own build linked to this post. If you already have the app installed, you will have to uninstall it first because signature is different.
You can see the full source and the changes on my github : https://github.com/pec0ra/Pimp_my_Z1
Special thanks to @Androguide.fr for his great app and to @B1nny for his link

Good news to have a new kernel dev for our beloved Z2 !
However, I've tried to flash your kernel, the flashing process seems to work correctly but actually I stay stuck to the last doomlord advanced stock kernel. Any suggestion ?

You should try to extract the .elf from the zip and flash it via fastboot
Code:
fastboot flash boot <name>.elf
Anyone else experiencing the same issue ? Maybe I did something wrong in my zip.

I think you mean the .img file instead of .elf.
Other than that, the kernel works fine for me. I did manually flash it via fastboot. (because I prefer to flash it via fastboot)
I took a quick look at your updater-script and compared it to Doomlord's updater-script and this is what I found:
Your script tries to write the kernel to this partition:
Code:
/dev/block/platform/msm_sdcc.1/by-name/Kernel
While Doomlord's script writes the kernel to this partition:
Code:
/dev/block/platform/msm_sdcc.1/by-name/boot
Maybe that's the culprit?

Yes, I meant .img. It seems like it'll take some time to get used to this new device. The kernel destination you pointed out is probably the issue, yes. And that's probably the notification problem too. Seems like the kernel never got flashed so it's logical that notification mod doesn't work...
I'll change this tomorrow morning
Maybe someone can test it until then.

That's due to Sony's RIC being enabled by default. If you look at my previous post where I mention it there is a command you can run in ADB to temporarily disable it, not ideal but it will help you rename the file.

First of all, I have spent a lot of hours on this project, trying to obtain the true power of this great device.
This Kernel is designed for optimize battery life and give more performance than stock kernel.
Features
Based on lastest sources, 23.5.A.1.291
DRM injection inside the Zip, you don't need flash DRM Fix, just kernel
OC up to 2,7Ghz
UC for better battery life
Optimized voltage tables and voltage control
Thunderplug v5.4, a load based hotplug and optimized for multi-core devices and it is very battery friendly with a great performance
IntelliThermal v2, a custom thermal control better than stock one
GPU overclock up to 657Mhz
Kcal control
More I/O schedulers like FIOPS, Zen, VR, BFQ...
init.d support
Power suspend driver v1.5
Build with UBERTC 4.9 and some optimizations
More stuff that I don't remember
ToDo
Add more governors
Share interactive governor tuned settings for battery and performance
More GPU optimizations
F2FS support
More battery life optimizations
Maybe Quick Chargue 2.0 support.
Maybe sound optimizations
Installation
Install my lastest TWRP (go here)
Make a backup of the partition System (MUST DO, because the kernel change some modules on system)
Select a version according to your needs. (See below)
If you have a TA partition backup:
Download EliteKernelZ2-(current version).zip and extract the boot.img on your pc.
Use the ta_poc tool by munjeni with your TA partition backup.
Rename the new_boot.img to boot.img and replace it on the EliteKernelZ2-(current version).zip
Boot on FOTAKernel recovery, with the phone power off, press at the same time power key and vol- until the phone vibrates.
Flash your EliteKernelZ2-(current version).zip with the boot.img patched.
Enjoy!

If you don't have a TA partition backup (so you need DRM FIX):
Boot on FOTAKernel recovery, with the phone power off, press at the same time power key and vol- until the phone vibrates.
Flash EliteKernelZ2_D-(current version).zip
Enjoy!

Usage with eXistenZ 5.6.5 and Magisk
eXistenZ 5.6.5 includes a TWRP recovery inside the rom, and we don't need it since we have some options for recovery here, so for remove it download this file and flash it on recovery.
eXistenZ 5.6.5 also includes SuperSU on the rom and for correclty install magisk we need to remove it, so first of all update the SuperSU app on the Play Store, after go to the app and on settings there is an option for uninstall SuperSU and unroot the System, so tap it (Sometimes if it takes more of 3 mins, close the app and do it again), after that reboot the phone and done, SuperSU uninstalled.
Now the installation/upgrade of magisk using my kernel.
Download the lastest magisk zip and magisk uninstaller zip here, put they on SD card.
Reboot on recovery, uninstall magisk with the uninstaller zip if you have it, flash the kernel zip, flash magisk and reboot to system, and done, enjoy magisk.

v3.4.13
Kernel made from scratch, so no special features for now (Sorry guys I do this for a better kernel).
Implemented last_kmsg for a correct bug report.
Updated linux kernel version from 3.4.0 to 3.4.13 (Correclty done and free of strange bugs).
QC 2.0 enabled (don't expect miracles, it is limited on Z2 so it works with some QC 2.0 chargers)
Full compatibility with Magisk, eXistenZ and ta_poc tool.

v3.4.33
Updated linux kernel version from 3.4.13 to 3.4.33.
Enabled a kernel flag for try to enable Assertive Display on Z2 (It just give me logs that help me to know what is happening).
Dropped TWRP inside the kernel, since I have build newest TWRP for Sirus, for FOTAKernel partition. It has more features and it is more bug free than recovery inside the kernel.

FAQs
How to report a bug?
Give me a last_kmsg, current version of the kernel and your rom.
Can I flash over Abricot v8.1?
It seems that flash over Abricot creates bugs and bootloops so make a clean install and enjoy my work
Note:I'm not going to support any user that don't make a clean installation
Now you can contact me at Telegram: #ShadowElite117, easy way to find me fast.

I will try this kernel with the quick charging patch. I hope it works
Post: http://forum.xda-developers.com/xperia-z2/development/sony-secret-revealed-qc-2-0-t3163490

This kernel has potential! will wait for further updates.

All working good,I have a really nice uv for 268mhz - 635 mv stable after 30min of stability test
Btw fiops is set as scheduler after reboot,is it because of your preference or bug in kernel adiutor?

Flashed

It is my personal preference, sony set ROW as default but sometimes has performance drops, fiops is more optimized and better for performance.

Nice! Testing right now, i'll report later

Just look at it

My existenz 4.7 and abricot kernel v8.1 has 59k-60k score points. I have not tried this kernel yet. Really good for you
btw do i have to reset my kernel adiutor before flash new kernel?

Great work, I'll try it asap with @Debuffer's Gov-Tuner Project, which I'm using actually with the stock kernel and works flawlessly.
I'll report the results
Thanks!!

I wonder why mine was so laggy at gpu test,your had the same problem? I think its not kernel related anyway,probably adreno 330 just gets old. ^^
My worked without any reset in kernel adiutor,I only wiped cache and dalvik but I think its not necessary. All previous settings worked without problems.

Yes i had same problem. GPU test was very laggy. Thank you for info, i'll try this kernel.

I would really try your kernel, but I dont have unlocked bootloader yet. Is there any disadvantages by unlocking bootloader? I hear that camera didn't have enhacements like noise cancelling, but I made copy of TA partition. Did your kernel will fix that if I unlock it?

It is stated in title that DRM fix is included so no need to worry about disadvantages. But remember to keep your TA partition copy somewhere safe in case you will want to lock the bootloader someday.

Yes you need to unlock your bootloader, and you should make a TA partition backup, also my Kernel restore the lost functions with DRM injection and if you want your original DRM keys working, also I will put the method, for now I'm on University and I make the post tonight so give me some time for all stuff that I have.

Don't worry about lag on test it is because it is a really heavy test so GPU is fine

Thank you for good job
Is this a big kernel bugs?
It is suitable for everyday use?

Do you have specific parameters that you use to enable all of the features within the kernel, for example, the hotplugs and the flops scheduler...
Do you have a kernel management app that you could recommend to me, for example Kernel Auditor?
Thanks for your contribution toward the Z2 line, I really appreciate it and look forward to more from you !

Screenshot of kernel booted

First impressions are it's really smooth and seems to have great battery life compared to the last kernel I was using so I think this is a WIN. I been pretty busy lately so I haven't been doing much to my phone but I'm glad I can hop on XDA for a few mins and flash something to make my phone perform better without me having to use scripts to improve anything. Good job

Great, thanks for sharing.
Compared to androplus kernel, what are the pro/cons?

Not booting my phone with this kernel. I am using eXzistenZ v8 custom rom. Androplus Kernel v29 is OK.

i can also confirm not working on existenz rom v8.0 but it will work on stock one probably.

I can confirm it working on stock rooted ROM
There might be a slight lag but a fix by turning stamina mode on then off will fix it
Standby time will be reported in a few days

It seems like whatever settings we had before we flash kernel is what it uses as config. So in my findings it keeps the scheduler values and Governor values the same. So I had to edit these values as it did cause a issue. I was using duality kernel prior.

I agree, I suffered noticable lags when I enabled Deez nuts 8 SE and with the kernel at the same time

Holy smokes, works very well on my XZ. I also used your kernel, which is also very fast, thanks!!

Did you will make kernel for Oreo ?

I'm too lazy to upload it and I removed some core features e.g. CPUQuiet, frandom,... because they doesn't work well on stock.

NOTES
1. Use AR_Beast Adiutor to apply settings(prebuilt in kernel zip)
2. Always turn on Apply on Boot and set Delay to 10 seconds or more
3. Always turn on Emulate Init.d option in Kernel Adiutor.
4. If you are facing WiFi/Hotspot issue then check whether your system partition has atleast 20mb free then reflash kernel or Extract wlan.ko from the .zip of kernel (located under system/lib/modules/) and place it in root/system/lib/modules/ overwriting the one already present there. Then, set the permission of the file to rw-r-r and reboot the phone. Use ES File Manager with Root Permission to do this.
5. Facing splashloops(loops on yo logo) then clean flash your rom or wipe data/cache/dalvik-cache
6. Don't use any hotplug along with core control or quad core mode if you wanna use hotplug then disable corecontrol and quad core mode. You can use Core control along with quad core mode.

PRO Sir!!

Thanks for Oreo Support Bro.,

Can we use it for nougat also ?

Will R9 version Support Nougat?
Please reply me. If not which ROM is preferrable to install? Suggest me.

Has anyone tested if this kernel works fluently with NitrogenOS 8.1 ROM ? Please do confirm as this kernel looks so tempting.

The kernel Adiutor mod is broken. Can u give another link.

bro i am using this rom with my nitrogen os shekhawat 20180208 , it works super fine on nitrogen, trust me u can go with this kernel, everything is working fast and smooth

Wlan.co file is missing from the directory you mentioned. Where can I get that file? My wifi/hotspot does not work. Other than this this kernel works perfectly with nitrogen os 8.1.

thanks .. need the link for auditor mod ?
