[KERNEL][AOSP][LINARO-4.8-O3][N80xx][UNDER/OVERCLOCK][FAST CHARGE] MM_alpha-0.6

Hi guys,
since we haven't got any kernel for our omni roms I've decided to make one. For now it's just an alpha but to me seems pretty stable I'm releasing here as a test. Please report what do you think. It's based on "stock" omni kernel with overclock (for now I'm using this commits https://github.com/marco9333/androi...mmit/1d75a501447e609dbb412c350d79ac1ef720a630 and https://github.com/marco9333/androi...mmit/36cf4ca9c78144f336dad4af88049b4a6bf59fac but from next release I'll try @humberos commit https://github.com/humberos/android...mmit/5f768f943d0c420860575e22756b58ff64f0c596 as he suggested See changelog below).
I've tested on Omnirom and @nerdyblonde reported it is working on Carbon, feel free to try on any AOSP based rom (not Samsung based)
Features:
An awful name (I'll try to find a better one)
Different versions for n8000 and n801x
Overclock up to 1600Mhz (booting max freq is 1400Mhz) and underclock to 100 Mhz (booting min freq is 200 Mhz) -> version 0.2 and newer
I've added a (temporary) my commit https://gerrit.omnirom.org/#/c/9555/2 to force cpu frequency range to stock values (I'll decide about merging this in omni rom official builds)
Version 0.1 built with different flags and toolchains but from the next one I'll use only linaro (maybe I'll try sabermod too) See below
See changelog
TODO:
Add fast-charge -> I've almost finished this, I hope to post an update soon (maybe today) DONE
Add underclock (100 Mhz, see humberos commit above) Done.... version 0.2 and up See below
Change installing script to solve possible dialer problems with some roms (unpack modify and repack original boot.img I'll use https://github.com/ModdingMyMind/boot_manipulation but I'll need some time)
Add more schedulers and/or governors (???)
Tell me what would you like to have and I'll think about that
Add thanks to all the developers
DIRECT DOWNLOADS Version 0.6 (LATEST):

HOW TO INSTALL
(*optional) Make a backup (or just keep the original rom zip so you can reflash that to go back to stock omni without losing data)
(*not optional) Use this at your own risk I don't take responsibility for any crash, excessive heat, forced reboot, and whichever problem you could have
Flash the zip in recovery, no need to wipe anything, reboot
Thanks to:
* Omnirom team
* @iofthestorm (is the one who ported and made our devices official with omni)
* @humberos (underclock)
* @Lord Boeffla (overclock)
* @Christopher83 (I'm using his toolchains)
* See my sources on github​

Added underclock down to 100Mhz (Thanks to @humberos)
Added more build flags (Check http://forum.xda-developers.com/showpost.php?p=36693600&postcount=9 for reference)
Version 0.3
Added fastcharge support in kernel drivers(need some testing to check the best currents) -> Disabled by default but can be enabled anytime without reboot(Maybe an entry in Advanced settings??? See next post)
https://github.com/marco9333/androi...mmit/b3e4981b88be28d59ab01052cf3f66d5e411c88b

Now powerkey should switch the screen on faster (no lag between pressing and screen on) All credits to https://github.com/dsc-team/dsc-team-kernel-project Not working
Added some patches from linaro, they should give more battery juice-> got about +400 points with antutu if you believe in benchmarks... I don't
Version 0.4
Changed mounts flags for system,data,cache and preload (with antutu I had about 300 for storage I/O now is around 980-989 with cfq, got better result with row, test it if you find some improvements)
Added some patches from linaro (see my github)
Increased i2c speed with wacom digitilizer(I'll test this tomorrow)
Increased sampling rate of wacom digitalizer (S-PEN should beis smoother (IMHO))
Added init.d script editable by user to set cpu frequency,fast charge and s-pen tweaks(for now)
Fixed Broken charging animation when the tablet is off (I will merge this into official omnirom after some testing, maybe I'll release here before as a preview, if you're curious https://gerrit.omnirom.org/#/c/9658/) ->
Merged into omnirom, if you're using omnirom now this fix is present "by default", if you have another rom the fix is still installed with the kernel (Report if not working)
Backported xpad driver (xbox, xbox 360 and xbox one controller support) from linux 3.17 (Needs testing)
Backported ps2, ps3, ps4 driver from linux 3.17 (Needs testing)
Other minor changes

Reduced hdmi out resolution to 720p and set hdmi audio to 2ch (Quite useless now since hdmi isn't working)
Introduced compiler flags from JustArchi's github and switched to linaro-4.8.4 (should give a performance boost)
Version 0.6
Enabled previous added SMT (http://en.wikipedia.org/wiki/Simultaneous_multithreading)
Patches for conservative and ondemand governors
Added zzmoove governor
Enabled more governors (interactive and adaptive)
Other small changes (check my github)

How to temporary enable fastcharge​You need a rooted device but since you're using a custom rom I assume that you have it
Download a terminal emulator app on google play store
Open it, write su and press enter(superuser or supersu should popup, grant root access)
Write echo 1 > /sys/kernel/fast_charge/fast_charge to enable
Write echo 0 > /sys/kernel/fast_charge/fast_charge to disable
Done
This settings will be reset on startup, if someone is interested I can write a init.d script to set fast_charge on boot just let me know DONE. See below
Stock charging settings AC -> 1800 mAh USB -> 600 mAh
Fast charging settings AC ->1900 mAh USB -> 1500 mAh
How to set kernel parameter on boot (Version 0.4 and up)​
You need root and a root browser (like https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree)
Go to /system/etc/init.d and open 99mm_alpha file (it's a plain text file)
All the settings are commented
First section is for cpu frequency set on boot (by default max freq is the stock one so no overclock, try to set it with a kernel app, if everything is alright you can after modify this file)
The second section is about wacom pen, choose the sampling rate you prefe: higher means more smoothness, but possible higher battery consumption
Last section is for fast charge change the 0 in the last line with a 1 to get fast charge enabled at each boot (you should have echo 1 > /sys/kernel/fast_charge/fast_charge)

This is just for omni Rom correct? I rub carbon rom but I'd like to try it.

I haven't got time to try on other roms but should work with every AOSP based (like Carbon). You can always try it just flash in recovery: if the boot is ok then it's working, if you got a bootloop you can go to recovery and reflash the whole rom without wiping so you won't lose your data (I think doing a backup is better, just in case)

I can confirm the kernel works on Carbon Rom.. Underclocking works great... I don't overclock though.. Thanks for compiling this for us!

Thanks for taking the time to create it and thanks nerdy for testing

Phone fc is quite strange since you are using a n8013 which don't have a modem. In n801x version of the kernel isn't included the modem driver, so this is the cause of that force close IMHO. You can try two things:
Go to settings-> apps-> all-> dialer-> disable -> reboot and check (now phone app is disabled so it shouldn't crash since is not running)
Or download and flash n8000 kernel. (with the modem drivers so the process can't complain anymore)

I have a N8013 as well.. I didn't get any force closes.. I uninstall all system apps I don't use, the dialer being one of them.. I flashed thru TWRP.. Hope you get it working

Ok that would make sense since I never uninstalled the dialer app. Never needed to lol I will try and report back. Thanks.

Couldn't even get there. The FCs happen too quickly. After closing a dialog it immediately appears.

When the message appear do not close the dialog but try to pull down the quicksettings and go to settings from there... If this won't work I'll add a script to kernel zip to clean dialer data (if possible) so you can easily flash directly without further actions

Thanks for this Marco, it works great here- Omnirom on a n8013. :good:
Is there any chance you might take over the omnirom development now that iofthestorm is out of the loop? He mentioned he was up for helping someone who was willing to continue the work on it.

[i9506] [Touchwiz] [Lollipop] FireWork Kernel v0.4.0 *DISCONTINUED*

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.

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?

Good job, latest official nightly boots no problem. The only thing is root access isn't showing in developer options, therefore no root..

A small update (20150531) for a petition made by haloass65.
Recompiled just to enable CPU OC.

Great kernel!
Are there any chances to get in the next version a couple more features?
1. Enable Call Recording
2. Add support for F2FS for /system partition
3. SIO scheduler
4. USB OTG (with Y adapter)
5. GPU OC to 600 MHz / GPU UV

I want to add a lot of stuff but it's hard and I am trying my best!
I tried f2fs on system in my first release. I mean I can modify fstab file to make it mount system as f2fs partition but the problem is with the recovery or the CM-12.1 flasheable zip. I tried to modify the update-script inside it but it did not work, it changed system to ext4 automatically, so I decided to leave it as ext4 without journal for now. If you or someone can make the CM-12.1 flashable zip work with
f2fs, I can modify ramdisk again.

Good job, latest official nightly boots no problem. The only thing is root access isn't showing in developer options, therefore no root..

can you try 20150521-2 version?, It's back Root access under developer options menu.

Nice to see your comments and your own desire to make it even better!
For /system I menat actually to support both ext4 and f2fs, for example as it's done in the f4k's kernel. And yes, of course this means manual modification to every CM12.1 update ZIP - but those, who go the way of /system f2fs migration are normally prepared for that.
As for the schedulers - not only SIO, but also ZEN would be welcome, as well as Lionheart for the governors...

this kernel only works with system(ext4), /data(f2fs) and /cache(f2fs)

So, this means that I can't use this kernel with the stock CM12.1 image?

it won't boot if you have all partitions formatted with ext4 like stock ramdisk CM12.1 brings them.
I could try to implement f4k's script which is capable to detec the type of partition and it does not matter whatever your partitions are.

Thanks, will try 20150531-2 in a couple of days when I get some time and report back then.

Great kernel!
Are there any chances to get in the next version a couple more features?
1. Enable Call Recording
2. Add support for F2FS for /system partition
3. SIO scheduler
4. USB OTG (with Y adapter)
5. GPU OC to 600 MHz / GPU UV
Click to expand...

correct me if I am wrong but Call Recording is more related with Rom, not kernel, isn't it?
I was taking a look at f4k's source for USB OTG, I won't be able to test it because I don't have the cable but I could try to implement it. I am working now with his script to autodetect filesystem partitions.

Call record, to be done properly, should be first correctly supported by the kernel and in most cases needs root (there are of course some exceptions, like Defy Mini default firmware or many China devices, that have it from the stock). Then there are either apps to call this function, or the system (firmware or if you call it ROM) apps, that also may have or may have not this function. But until it's activated in the kernel - apps can't use this function (ok, can't use it properly. There are some cool apps like Boldbeast that are so clever that somehow manage to record calls properly even on the not-rooted devices without standard kernel support for the feature. Don't ask me how they do it' I don't know this secret.. ). BTW the official cm12.1 for serranoltexx has brocken call recording feature since recent nightlies (frm apprs. 20.05.2015), so there is no way to check its internal functionality for now.
For OTG, hence our device don't have the power output on the USB port - we need to use the OTG Y-cable with external power supply. I don't have it atr hand at the moment, but as soon as I get it - will be happy to help testing.
Anyway, so far the kernel is very good and is not over-bloated with too many features. I'd say if we stop on implementing my list of the 5 requested features - this would cover 99.9% needs.
Really, it's great to have a custom kernel that works fine with official CM12.1. Thumbs up for your efforts!

Absolutely pointless to insert these schedulers and governors.
On this phone ATM the FIOPS and DYNABOOST is the best combo that you can get.

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.

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

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)

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:

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?

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.

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!
