Goals and their priorities
- Stability #1
- Battery life #2
- Speed #3
- Extra features #4
- Compatible with GLaDOS Control / Franco Updater App / Trinity Toolbox #4
Donations will soledly be used to buy the applications above mentioned or to share it with the developers I used their work from, so I can test compatability more often.
Everyone can make changes to this kernel. The only thing I will require from you is a SSH key as described in the help from github. This way everyone can contribute to this kernel. Extreme changes to the kernel must be approved by me or someone else I assigned to help me lead this project.
Are you interested to help? Sign up!
Developers list
- Jonas Hendrickx - djjonastybe
Features (what you see and experience) (also future features listed)
- Compiled with latest Linaro Toolchain
- 3.0.41
- CPU: enabled 1500MHz
- GPU: enabled 384MHz
- Fixed several bugs present in the stock kernel
- Custom Voltage
- C4 State (Cores can be turned off) + OSWR
- Customized compiler flags
- Color Control (Ezekeel)
- Vibration Control (Ezekeel)
- Sound Control (Ezekeel)
- Enhanced undervolting MPU/IVA/CORE
- No crappy workaround patches so we have a clean kernel.
Want more features? Want to see something removed? Want to see something changed? Please suggest. I don't eat you alive.
Coming soon
- Improved GPU Scaling 128/256/384MHz (Improved battery)
- Tweaked DRAM timings
- Requested: Trinity color palette source code
- Requested: Live OC (I don't like some aspects of Ezekeel's implementation. I believe some things can be done much shorter and much more efficient.)
This kernel focuses on changing bus speeds, removing useless code, and adding only useful things to the kernel.
Tweaking has been done carefully.
https://github.com/jonashendrickx/MAGURO-JB/tree/android-omap-tuna-3.0-jb-pre1
We do not want to exceed the limitations on our device. Don't ask for 2.0ghz overclocks or 512mhz GPU. It's still a phone and it will always be one. I will add it when I am ready.
Want to contribute to Speedy Kernel? Read the requirements.
Requirements:
- Knowledge of github
- Generate a SSH key and send me the public key: eg id_rsa.pub.
- Know that I can revert your code and accept this. It's still my kernel.
Depending on how much people want to work together on this kernel I might start a kernel which is open for anyone to edit. Only I will setup the repository.
First!
You here too!

Hahaha nice one!, i also sold my NS, and im getting my GN sunday , see ya ssoon
I am wondering how I can activate SLUB. I don't know what Android is using for stock. But apparently some devs use SLQB. I read SLUB is little faster when using Google Search.
I am going to make a first upload.
More features are coming ofcourse.
Uploaded. Please flash with fastboot. I am not going to make update.zip files. I find it faster and more efficient to do it this way. I might look into making update.zip files later
Released. Update.zip also.
Currently I have only enabled the green features. More is coming.
Do you at least know what is SLQB and SLUB ?

Not yet. I don't know how to upload to github. I have spent a few days on it before. I know my way working with the git I cloned. But uploading is still new to me.
Feel free to teach me. I have everything in this folder:
/Android/jb/maguro/omap
I know how to create a SSH key and upload it on my Github page. But then the uploading part doesn't work.
I may take a look into it later.
waiting for next one , interesting...
Uploaded!
PGM app support or not?

Is it possible to include option to turn FSync off?
Sent from my Galaxy Nexus using Tapatalk 2
Looks interesting, I'm installing it now.
Fast Charge would be a nice addition though.
Good to see a Belgian developer join the scene!
I don't know. I think you can turn off FSYNC with GLaDOS Application. I am not sure. I am still new to the Galaxy Nexus mods.
I will take a look into enabling PGM app support if I can disable it for those who don't use it.
Rcbrt thank you! I will try again github tomorrow night or maybe upload everything sunday.

Reverse engineer this ?
Don't know if this will work but as far as I know it's not required by Jelly Bean?
Is this a good Idea ?
I am currently testing it. See my CM10 thread for the latest nightly to try this. This should fix all overclocking issues hopefully
Source code:

very good
Very very very good work guy .....
Why do you want to remove the HAL? As soon as it was fixed we didn't have more problems setting the clocks during screen on/off, so I don't see a reason to remove it and in the end it should cause more problems that its worth.
Steve's comment makes me worried:
Why not just make the code a little smarter and detect this stuff automatically?
Soon we will be using boostpulse in many more places in the framework to improve interactivity in ways that can't be done from the kernel alone.
Click to expand...
Click to collapse
Using boostpulse in the framework is NOT smart at all. I think this stuff should be done in the kernel level only. Other devices have other types of code to boost the frequency when it receives a touch event (all kernel level) instead of merging it to the userspace framework.
===>INTRODUCTION<===
This is my personal kernel based off of ASKP. I cherry-picked a lot of custom commits from many big kernels. I'm new in development, so, any help whatsoever (commits, suggestions, logs, etc etc) would be greatly appreciated
releases will be as frequent as possible, as I'm gone for 7 hours of my day during weekdays.
****FEATURES****
using A.S.K.P as the base<- you get all the features of A.S.K.P+ more
linux kernel 3.101 WITH the Con kalivas patchset for improved performance
L3 cache overclock (116MHZ)
custom RAM OC setup (333MHZ/400MHZ/466MHZ)
gpu oc interface (307/384/512)
optimized CRC32 computing algorithem
optimized square root interger library
custom voltage setup,modified by me personally taking inspiration from the voltage's of other kernels,everything from the GPU voltage to the screen regulator has been tweaked
CPU overclock up to 1.7GHZ
multiple governors i have personally added (this is ALWAYS changing considering what jhonny/grarak/faux/bsmitty/Amperific/boype do to their governor,or what i personally decide to do)
some new IO schedulers have been added
EXFAT is added, 1.2.5 source from dorimanx
updated RWSEM to linux 3.14
numerous enhancements to SLUB including a update to the 3.3 version
MMC software updates/enhancements
GPU side enhancements
HUGEMEM setup (this is a arguement from me personally,the gnex is only a 720P phone,you cannot utilize 1080P with out screen,so even if this is a retarded and dirty hack,i want to use the extra available ram)
ALL kernel logging has been disabled for a increase in speed
Kernel SamePage merging has been updated to linux 3.6 standards with faux's check page patch for improved performance and efficiency
memory Compaction updates for better performance
modified screen colors
imsoyen's SmartReflex 1.5 tuning interface
updated thermal framework drivers from faux & omapzoom
updated android binder.c from omapzoom's 3.8 branch that bsmitty discovered
updated logger from poondog,linux 3.9
graphite and link time optimizations including -o3 and hard float point with NEON with the latest linaro 4,9.1 toolchain from christopher83,compiled with graphite ops on gpu code along with -o3
zcache,zsmalloc and zram updated to linux 3.11 from mpokang kernel with faux's setup for zram
many misc enhancements from AK kernel
many misc OMAP enhancements
the latest WIFI drivers WITH a working hotspot
a modified anykernel zip package that will install a new HOSTAPD binary for working wifi hotspot and new meda_profiles.xml to fully disable 108PTHIS KERNEL USES VERY HIGH CLOCK SPEEDS WITH VERY LOW VOLTAGES,I BUILD THIS KERNEL THROUGH A "PERSONAL" SETUP,IF YOU GET SOD'S/ FREEZES,PLEASE UP YOUR VOLTAGES ON "MPU" BY 25 UNTIL THEY STOP :3
IF YOU'RE GOING TO USE A HOTPLUG GOVERNOR, FOR ALL THAT IS HOLY DO NOT USE MULTICORE POWER SAVING WITH IT. THIS CAUSES ISSUES AND NO BUG REPORTS ARE ALLOWED IF YOU HAVE HOTPLUG WITH MCPS
BUILDS:http://patty.mbqdevelopment.com/Kernels/ASKP Remix/ <- the numbers are going to be in order,the bigger the better XD (thanks to mbq for the generous hosting site,or as i like to call him,"big brother" thanks man :good: )

thanks man,means alot! really do appreciate the support!
Flashing it as I type
Will report soon, it's good to see new kernel from people in this gnex threads
Edit: got my first freeze, lol. Maybe the voltages are too low, I guess?
But I got a couple questions:
1. Did you intended to UV voltages, including IVA? I see it lower than DirtyV and Franco.
2. The frequency steps..... There's a lot of it, but is it correct? There are numerous voltages that are new to me lol like 460, 1480, 1560...
Maybe you could explain just a little bit lol
Edit2: pattyboi did you implemented early suspend on interactive? There's a slight lag when waking up the device
Btw there's pegasusq, too.
This is how it starts you are now entering the Linux twilight zone of the quest for the best kernel patches go get em @pattyboi:)

sorry for the late reply bud,i fell asleep after getting that 2nd build up. the 460 is gonna be removed,as i said im still nooby and i didnt add it right :silly: the rest should be correct as i didnt touch any other one,the uv voltages were just burstlams slight uv on regulators,i havent touched anything with iva,mpu or anything else,ill probabaly bump them up a lil within the nest couple days still gotta wrap my head around how to properly do it lol. but thank you for testing man! & yeah the interactive early suspend i "think" is there,is 7 am so im not entirely sure,if its causing wake lag i might try and switch the interacitves or just remove early suspend,like i said its a big mess i gotta iron out
EDIT ,one more thing,did you disable eco mode? that might cause wake delay because it was for me

Take it easy bud, we're all here learning as well lol
Yeah I'm not using eco mode and intelli-plug, not liking the less-snappier feel lol.
You could take interactive from either bsmitty's or Franco's, I think they're making out the best interactive so far. :good:
Also, this kernel has GPU governor. Is it overclocked as default?
Btw, I'm suggesting to do some wrapping on your OP. Because your kernel has many features inside lol :laugh:
Thanks!

E980 Kernel+
***I am not responsible for you bricking your device or causing any other unwanted outcomes to your device. Be careful and smart. If you don't know what you're doing you probably shouldn't be flashing this.***
This is the E980 Kernel+The end goal here is to have a kernel with more features and potentially much better battery life. I can only guarantee it will work on E980, not sure if it will work on other devices. I also do not know what ROMs it will work on. That is up to you to share. Rule of thumb is, if it's CyanogenMod, it'll work.
Suported Devices:
E980
E988
***If you are interested in building your ROM with my kernel, you have my permission to do so. However, if you could just let me know, that'd be nice. Also a credit would be appreciated but is not necessary either.***

I highly suggest you are rooted and busybox'd.
Note: If flashing fails and you are on a CM11 ROM, you may want to try flashing original kernel or earlier version before reflashing your ROM or clean installing.
To-Do List:
-Faux Sound - Done.
-Governors/IO schedulers - Done.
-More TCP congestion controllers - Done.
-Replacement for Qualcomm's MP-Decision (Intelli-Plug) - Done.
-Support for actual GPU underclocking (Maybe save battery since it always runs at top freq when it doesn't have to.) - In the works.
-Support for undervolting - Removed for now.
-Lower clock speeds than 384 MHz
-Higher clock speeds than 1728 MHz
-Intelli-Thermal - Done.
-Fast Charge - Soon.
-Battery Life eXtender - Soon.
-Knock On/DT2W (May not add due to battery drain issue that comes with)
-Keyboard USB support
-Linaro Performance Toolchain - Done.
-Support for F240 - In the works.
-Anything else?
***Make note I do not know if I can implement all of these but I will try my best***

Toolchain: https://github.com/Snepsts/linaro4.7gcc
HOW TO BUILD
At this point if anybody wants to try out the kernel before I make releases, you are free to compile it yourself. I would like to ask that you do not share compilations just because I like to track how many people download and use the kernel through my goo.gl links and the afh download counter. I don't like it when people rehost my kernel since it gives me misguided numbers on how many people are following my work. It's just personal though, I'm not going to stop you. I just like it because it gives me an idea of how many people are using my work and kind of makes me want to keep working on it since I know how many people still use it.
Anyways, I'll leave instructions to compile right here:
This is assuming you're using a Linux distro (VM or not, has to be 64-bit) Pretty much everybody recommends Ubuntu, and that's fine, but if you want my suggestion Mint runs like a dream. Anyways to building!
You'll need to get the required packages. I forget these off the top of my head, but they're something like this:
Code:
sudo apt-get install -y build-essential kernel-package libncurses5-dev bzip2 abootimg
There might be more, idk. This should get you through the build. Let me know if there's anything else.
Next we'll make a directory and grab the sources.
Go to your main directory to store the android folder in (for tidiness sake), if you have a preference you can do this differently. If you're not sure what you're doing here, just go from where you are (should be your main dir):
Code:
mkdir android
cd ~/android
git clone https://github.com/Snepsts/kernel_e980.git
This might take a while... when it's done you should have a folder called "kernel_e980" in your android directory.
While we're downloading, go get the latest M build or the latest nightly of CyanogenMod: https://download.cyanogenmod.org/?device=e980
This will be useful later.
Now we go grab a toolchain. My favorite is this one: http://www.mediafire.com/?x7lgbeprpg8gn choose the cortex A-15 one. Untar it and move the folder wherever you like. I suggest the android folder to follow the rest of the guide.
Code:
cd ~/Downloads
tar -xvf arm-cortex_a15-linux-gnueabihf-linaro_4.7.4-2014.06-build_2014_09_13.tar.xz
Now move this folder through the GUI (Graphical User Interface), much easier than more commands imo.
Now rename the folder toolchain, just because it's easier.
Now we're ready to build. The username is whatever your Linux username is.
Code:
cd ~/android/kernel_e980
export ARCH=arm
export CROSS_COMPILE=/home/username/android/toolchain/bin/arm-cortex_A15-linux-gnueabihf-
make cyanogenmod_e980_defconfig
All ready to go
One last thing, before you make it, if you are a little more advanced and need to toggle something or do anything else, use:
Code:
make menuconfig
You probably don't need that.
The # means the amount of cores in your computer's processor +1. For example, my Linux virtual machine has 4 cores allocated to it, so I assign it -j5. Now to make the kernel:
Code:
make -j#
And watch the words flyyyyy.
If anything fails, double check you didn't mess up. Also, the current Github build is never guaranteed to succeed.
Once the build is completed, you should see something like:
zImage is created!
Or something. Now go to your Downloads and get the boot.img out of the CyanogenMod build whatever way you wish to.
We'll leave it in the Downloads folder for the sake of the guide:
Code:
cd ~/Downloads
abootimg -x boot.img
Now you should have a zImage, intrid.img, and a bootimg.cfg. Ignore the zImage, move the intrid.img and bootimg.cfg to the ~/android/kernel_e980/arch/arm/boot folder.
Now we finish the kernel:
Code:
cd ~/android/kernel_e980/arch/arm/boot
abootimg --create boot.img -f bootimg.cfg -k zImage -r intrid.img
Done! Your kernel will be the boot.img file.
Replace a current kernel.zip's boot.img with this one, you can use any of the E980Kernel+ .zip folders for this. Just remove the boot.img in that one then put yours in it. I always upload my kernel to Gdrive and then download it to my phone to flash. But whatever you wanna do from here is fine.
And now you have the latest version of E980Kernel+ Unofficial. Yay you!

About E980 Kernel+
In this post we will go over some of the things in this kernel and shed some light on what they do... Let me know if you have any information to contribute or anything else
Intelli-Plug
Intelli-Plug is developed and updated by Faux123.
Intelli-Plug is a hot plug replacement for Qualcomm's proprietary MP-Decision. MP-Decision essentially decides the final factor on clock speeds, when cores go offline, how long they go offline, and they generally manage your CPU. There is a lot of discussion over whether or not Qualcomm's solution to hot plugging is efficient or not. Intelli-Plug is an open-source and updated version of MP-Decision in which anybody can contribute to and improve. It uses different methods for arguably better performance and better battery life. The current version used is optimized for MSM-8960 chipsets (like ours). It is updated and even offers convenient profiles to optimize battery life, performance, balance the two, or do a little between each option. Some of the profiles allow an eco-mode like experience. Eco-mode is a depreciated feature of Intelli-Plug that turned a quad-core processor into a dual-core, effectively optimizing the processor to run like a dual-core and save more battery power. In order to toggle the profiles option without paying 5 dollars for the Faux Clock app, you may use a root explorer (like ES File Explorer), go to sys/module/intelli-plug/parameters/nr_run_profile_sel and input a number anywhere between 0-5.
I prefer this option ON and do not currently have a profile preference. In my experience it improves the overall device (performance/battery life) with no noticeable drawbacks.
Intelli-Thermal
Intelli-Thermal is developed and updated by Faux123.
Intelli-Thermal is a thermal replacement to Qualcomm's proprietary thermal solutions. It is open-source and anybody can contribute to it. It has optimized thermal performance and is arguably more efficient than stock thermal settings. In addition to being an open-source and updated module, Intelli-Thermal offers customization such as: personal selection of cores to throttle at a self-determined value, and a similar selection for cores to offline (minus core 0, since it must be online at all times). Intelli-Thermal allows you to set your own rules (do not set the limit too high) and thermal values are in Celsius.
I prefer this option ON, and set Frequency Throttle Limit to 70 C, Core Offline Limit to 65 C, enable all cores for Frequency Throttling Cores, and enable Cores 2 & 3 for Offline Cores. Rarely do I ever experience heat, and if so it is very minimal. The device may lag or get hot depending on your settings, so please be careful or mindful of what you set. This works better on some ROMs than others.
*** Personal Note: These two are of my favorites because they are optimized and make for a better experience with little to no performance drops. This is just my preference, and it can be chosen to follow as a guideline by your discretion. ***
Multi-Core Power Saving
This is a normal kernel feature.
Multi-Core Power Saving is a basic feature that, depending on the profile selection, groups tasks to a certain amount of cores. 0 is off, so the device runs as normal. 1 is on, and will try to group tasks into single cores or multiple cores at lower frequencies to save power, but will not force it. 2 is aggressive, and depending on the user, may find that this causes a little more lag as the phone really hates using any extra CPU juice for anything, processes may be clustered and slowed down from this, but battery life is also the best at 2.
I prefer this option set to 1, as it has no noticeable lag and seems to still optimize the battery a little more. This option varies from user to user.
Faux Sound Control
Faux Sound Control is developed and updated by Faux123.
Faux Sound Control is a custom feature that enables sound manipulation on the kernel level. This feature will allow you to modify the gain (Make sound louder at the potential cost of music quality or lower for ear protection) and other various settings from a kernel level. This is completely user preference and will vary from user to user.
Intelli-Demand CPU Governor
Intelli-Demand CPU Governor is yet another feature developed and updated by Faux123.
Intelli-Demand means Intelligent On Demand. On Demand is a kernel CPU Governor that comes as the stock setting for most phones. But it tends to be a little less than optimized and such results in sub-par battery life. Intelli-Demand is a tweaked version by Faux that will allow for similar performance and better battery life. It is also popular for gaming as when the GPU 3D load gets heavy it will perform like On Demand as not to interfere with game loads.
This is my current preferred CPU Gov as it has never given me problems and works like a charm.
I/O Scheduling
I/O Schedulers are different ways of controlling the input/output stream of information in with the memory of a phone. These generally do not vary too much in performance or battery-life but everybody seems to have a preferred one. I don't have a favorite and switch between noop, row, and zen from time to time again.
My only preferred setting here is setting the read-ahead buffer to 4096, as it increases speed and performance without any real hit to the battery.
TCP Congestion Control
I am not very well versed in TCP protocol or anything in the sort, but this basically controls how your phone interacts with Wifi/Data packets.
My preference (and, from what I've read, the general consensus) points to the Westwood TCP Congestion Controller. Never had any problems with it, too lazy to benchmark them.
I will add more later, and as I add features to the kernel, I will add explanations! Also, I plan on buying the Faux Clock app soon simply to figure out which profile is which (since the information is nowhere to be found) and then I'll return it and report the numbers back here. Also, whenever Cyanogen decides we're ready for CM12 official, the kernel will be ready for CM12 too. Please bear in mind that I hate updating and am not one with the Github (nor do I have time to learn about Github). Cheers! :good:
GOOD JOB:good::good::good:
And a little cpu overclock like 2ghz plzzzz ^^
Is it possible that you can create a kernel for F240?
Name... Hmmm

Hmmm... You posted the kernel for F240 to be compatible with E980 CM11 ROMs... right? If you can give me source for that I can try and add the same things to it as I am the e980. But I am by no means a dev or anything.

I hope I am able to deliver a kernel to you. By the way, what is the difference between F240 and E980/E988? I know E988 is international. Is F240 Viet or something? And what are hardware differences?

F240 is korean. I really don't know the exact difference between the E98x variants and the F240x. Maybe some kernel thingy.

Yes. VMware using Linux Mint 64-bit. My main machine is a Windows 7 with AMD FX-6350 (3.9 GHz) and 8 GB of RAM.
Here, read the guide mukwing gave me in this thread: http://forum.xda-developers.com/optimus-g-pro/general/making-cm11-0-kernel-e980-t2870820
That should be everything you need. Props to him he knows what he's doing!

I do believe there are some slight hardware differences which is what I read. I'm guessing the kernel you posted tells it to emulate an e980 somehow with the hardware. Maybe do something a little different to behave like e980. I don't really know though, that's just my guess. But yes I'll totally give it a shot if you can give me source.
Name it "Spartan" kernel or "Taco" kernel ?

Is the Taco kernel a reference to the flashaholic thread?
I like Spartan kernel though...
I was thinking of something like the "Ignis" kernel. Ignis is Latin for flame. Or maybe "Phoenix" kernel.
Knock on/double tap to wake please
Just tried to add some governors. Picked them right off of another kernel... I also copied and pasted the kconfig, makefile, and cpufreq.h files hoping that it would be the same... didn't work. Haha, guess I'll try typing in the config stuff myself and see where that gets me.
Adding features is the most headache things haha.
The commits from other device's kernel always not so compatible with e980 kernel.
Even commits from similar device's kernel like oppo n1 or G Pad 8.3 i still can't sucessfully incorporate them.
Without knowledge of programming, hard to find out what's wrong in the code.......
BTW, i have compiled a TWRP which can mount/read/write to F2FS formatted sdcard. But it lack the ability to format the sdcard to F2FS, need to do it in linux.(i am not sharing it because it still have chance of recovery bootloop)

Wow really? Damn I would have thought for sure HTC One kernels would have some similarity (Since we have identical processors).
Guess I'm learning C. I've actually made sense out of some of the programming already, but it's gonna be a ***** to get working. Thanks for the info though.
Good if you know programming language!
Waiting your kernel
But i will stay with stock lg for a while, haha.
Running this with acid and its running great, lost 2% between 11pm-6 in deepsleep:beer:

Machinex
MarkOneHundred
Sheer will .
This is machinex.
This is machinex. I have been working on this kernel for over a year now, and am finally comfortable with its release to the public. This kernel builds on the great work of those who have made this device the powerhouse that it is. There are elements here that you have experienced on every GS4 kernel to date, as well as other devices.
The goal I had for this project was upstreaming/updating/experimentally upgrading as much as I possibly could. I have done so, and will continue to do so.
This kernel is ONLY for TW-based, 5.0.1 roms for the I9505!!! NO I WILL NOT DEVELOP FOR DEVICES I DO NOT OWN, SAVE YOUR BREATH!
OBLIGATORY DISCLAIMER:
THIS KERNEL COULD VERY WELL DESTROY YOUR PHONE, YOUR LIFE, YOUR MARRIAGE, Etc. YOU INSTALL AT YOUR OWN RISK!! XDA AND I ACCEPT NO LIABILITY FOR YOUR DECISION TO USE THIS KERNEL!!For noobs: assume that installing this kernel will cause your phone to grow arms and punch you in the face.
PLEASE READ AND UNDERSTAND THIS OP BEFORE LEAVING USELESS "IT DOESN'T WORK" COMMENTS!
Issues that aren't answered here will be dealt with on a case-by-case basis.
SEE POST #2 FOR UPDATES, CHANGELOGS, and FIXES
SEE POST #3 FOR BATTERY/PERFORMANCE INFO
SEE POST #4 FOR A SHORT SYNAPSE BRIEFING
LOGS OR IT DIDN'T HAPPEN! Context helps too. What were your Synapse Settings?
KNOWN ISSUES Wifi issue is fixed! After a fresh rom install, all you need to do is reboot and the appropriate files are created in /data enjoy! HOTSPOT IS FIXED!!!! Finally! I AM AWARE OF AND WORKING ON LOCKSCREEN PIN BUGS!!
FEATURES:
- Linux 3.4.113 + a LOT of upstreamed subsystem code.
- Automatic Busybox Installation, Version 1.25.1.
- Cpufreq core backported ENTIRELY from mainline 4.13. All Cores operate independantly. Their governors and tunables can all be different.
- Govorners: Due to a highly upstreamed cpufreq core api, not many custom governors for now except for Interactive, Intelliactive, and the *NEW* Schedutil governor, described in the documentation like so:
The "schedutil" governor aims at better integration with the Linux
kernel scheduler. Load estimation is achieved through the scheduler's
Per-Entity Load Tracking (PELT) mechanism, which also provides
information about the recent load [1]. This governor currently does
load based DVFS only for tasks managed by CFS. RT and DL scheduler tasks
are always run at the highest frequency. Unlike all the other
governors, the code is located under the kernel/sched/ directory.
Sysfs files:
* rate_limit_us:
This contains a value in microseconds. The governor waits for
rate_limit_us time before reevaluating the load again, after it has
evaluated the load once.
For a great, comprehensive blog regarding the specifics of each governor, as well as the settings found below, please check out the link I've referenced in post #3.
- HARDLIMIT and THERMAL: Incorporated Yank555's CPU Limiting solution, Hardlimit. ALL hardlimits, cpu boost limits, and thermal limits are now PER CORE. I have included it directly in the core cpufreq code, and it is the primary controller for THERMAL, INPUT BOOST and user controlled hardlimits. Thermal overrides both user-selected and input-boost limits, and you can monitor the limiting in real time. Also, the thermal driver now accounts for each core's temperature, and saves time/lock-contention by skipping core control if the temps are below the frequency limiting value.
-CPU HARDPLUG: A driver I built that hooks into the main cpu hotplug API and allows you to disable any core you want, configurable for screen on/off.
- Hotplugs: MX Hotplug, personally built from scratch and uses a real-time kthread for its calculation work. Intelliplug 15.8 (Personally Updated), Alucard Hotplug, MSM_sleeper, Lazyplug, Blu Plug, and Bricked hotplug.
Hotplug Notes: I changed the names of certain functions in the Alucard and MSM Sleeper hotplugs, so that their tunables could be streamlined in Synapse. Synapse is cleaner and simpler than ever, but if you use a third party app, Alucard and MSM Sleeper's max cores and max cores during suspend settings will not be tunable. So anyone who uses a third party app with this kernel let me know and I'll devise a workaround. Mpdecision removed entirely. The "mpdecision" in our sysfs is actually bricked hotplug.
-GPU:Machinactive, Interactive, Conservative, Ondemand, Performance and Powersave GPU Governors, GPU touchboost (fixed suspend issue), ability to lock the min/max freqs, and more!
-Updated version of fauxsound (5.4) (flar2, alesaiko, me). I limited the options in the code to the 4 controls that actually work for our device, and you'll notice a significant stability improvement. Slimbus:Golden-ratio-based operation is pristine. Sound quality is hardware-perfected. The version number is largely arbitrary and I increment when I make any significant improvements. NO MORE USERSPACE CALCULATIONS NEEDED!!!
-A gamot of colour, brightness, and panel options that I frankly didn't think would be feasible for our device, but it's working! MDNIE HIJACK selection, KCAL, and Cyanogen's generic PCC colour control are implemented in Synapse. Note that MDNIE/KCAL stuff is a battery thief, and I've not tested PCC colour control enough for power consumption to give you a definitive statement on it. Note: PCC values are from 1000 (safety limit) to 32768 (or a number close to that), meaning your tuning control is as FINELY GRAINED as possible for this device. I can't believe Synapse actually supports its ridiculous number of steps (and well, I might add). Faux's generic "colour control presets' are in there and they actually work! The stock colours much more vivid, and lower brightness settings benefit from them as I have modified top brightness to my liking.
-HBM:Qualcomm High Brightness Mode: unlocked! This can be controlled via a checkbox in Synapse, but you can also use flar2's HBM widget from the play store. I tried it before and HBM would flicker, but i pulled off a VERY hacky way of making it userspace controllable. Be careful! Though it doesn't seem to drain the battery or overheat the device, it's purely experimental and could cause Chuck Norris to come to your house and personally smash your phone. Now SEPARATE from autobrightness! "SCREEN FLICKER FIX" on PAGE 2
- Completely upstreamed and overhauled cpu, power, scheduling...you name it. Updated Powersuspend to the point where I had to rename it, because it is now closely integrated with the core suspend/power api. Introducing: Prometheus. The driver now calls suspend directly when you turn the screen off, unless a) music is playing, b) the phone is plugged in or c) you choose to disable the feature.
-All the TCPIP tweaks etc, updates to random/frandom, android-specific autogrouping, limited but significant LMK/OOM updates.
-BACKPORTED "codel" fair-queueing net-scheduler, for a faster/more consistent networking experience.
-persistent ram, kexec-support, fast-charge, etc. Drop Caches button in Synapse is useful.
-Utilizing Qualcomm's built-in QRNGD (qualcomm random number generator daemon) with randomness optimized in the kernel = entropy for days.
-BOOTLOADER: Officially only 5.0.1 Bootloaders are supported. Unofficially, someone tried it with a KK bootloader and it worked fine for him so what do I know?
-COMPLETE Synapse support. Download, update, AND install Busybox On Rails from the PlayStore before you install the kernel for best compatibility and support. UPDATE: FULL Busybox installation is now included in machinex installer script. If you have any issues, still feel free to install Busybox on Rails. Upon kernel installation, you'll find Synapse installed in your system apps. If you want to get rid of it, just remove it from /system/priv-app with your file manager.
-CPU and GPU VOLTAGE Control: Both in Synapse. I DO NOT SUPPORT ISSUES IF YOU CHANGE VOLTAGE. YOU ARE ON YOUR OWN.
MENTIONS:
To those listed here, I cannot express how grateful I am for your assistence, patience, and kindness towards me as I badgered you throughout my journey. Though saying "thank you" doesn't feel like enough, thank you all. If I missed someone here, please tell me.

The Machinex Testing Team! - AMAZING folks, just amazing.
My Awesome Testers from this thread.
Again, I'm sure there's tons more.
On to the fun part then
INSTALLATION INSTRUCTIONS:More importantly, the uninstallation instructions. The install pretty much takes care of itself.
There are two links below that you must download in order to safely have an install/uninstall solution for this kernel. The one labelled "machinex-MarkOneHundred.zip" is the kernel. UPDATE: Busybox On Rails isn't required anymore. The second zip is crucial for uninstalling, aptly named "machinex-uninstaller-Jan12.zip." When this kernel is installed (and everytime it boots), it will rename mpdecision, thermald, thermal-engine, and power.default.so with an appended "-bak" suffix, because they all interfere with the updated power/cpu code in the kernel. If you switch to a different kernel, I INSIST that you flash the uninstaller (or take a look at the scripts yourself and do the stuff manually). ATTENTION: SLIM80'S KERNEL CLEANING SCRIPT IS NO LONGER NECESSARY WHEN FLASHING THIS KERNEL!!!!!! I HAVE INTEGRATED MY OWN CLEANUP PROCESS IN THE INSTALLER!!!!!!!!!!
TLDR: NO NEED FOR BUSYBOX ON RAILS, flash zip. use uninstaller zip to uninstall.
DOWNLOADS:
!!!JANUARY 12, 2017:UPDATE!! NEW UNINSTALLER for EVERY VERSION!!!!
DO NOT MIRROR THESE ELSEWHERE. DO NOT INCLUDE THEM IN YOUR ROM WITHOUT ASKING MY PERMISSION FIRST. I AM HAPPY TO COLLABORATE, NOT TO BE ON THE RECEIVING END OF BUG REPORTS CAUSED BY THIRD PARTY DOWNLOADERS.

(be gentle on my ridiculous commit history, my git skills are shoddy at best).
So keep in mind this a development thread, blah blah blah, but if we all have good discussions (let's TRY to keep it on topic), I'm more than happy to have some fellow nerd friends to talk about my passion with. Heck, I want to use this thread as a chance to meet some other developers who wanna work on stuff together, exchange ideas, learn, and teach me how to get better at git.
Enjoy!

UPDATES NOTICE:
Reset your fuelguage (in Synapse) after every install! WIping your cache and dalvik-cache can be helpful for stubborn apps, as well as wiping the cache of any specific app giving you trouble!
-------------------------------------------------------------------------
UPDATES - MarkOneHundred - October 31, 2017
CHANGELOG:
- Updated memory management to roughly linux 4.4.
- Modified Cpufreq in various ways. Per-Cpu frequency touchboost, per-cpu thermal core tracking and limiting, and governors can now be changed if a cpu core is offline. The governor selected will be applied to the core once it comes back online.
- Implemented Omniboost, a generic touchboost interface that can be used for any driver, so long as driver has an external function that the booster can use.
- Built a new hotplug driver from scratch, mx_hotplug. The driver chooses to on/offline cores based on a combination of system load and current number of scheduler requests (and touch of course). What separates this hotplug driver from others is that it uses a real-time kthread in order to give it an "interactive" type calculation.
- Speaking of which, found and fixed the issues with google's most recent interactive governor, and have added it back. Due to it working perfectly now, I forward-ported Intelliactive as well.
- Updated Hardplug to be more efficient.
- Built a little userspace hotplug driver from scratch for those who just need manual core adjustments.
- Tons of other little fixes and updates, to the kernel itself and to Synapse. Please explore around Synapse for some of the updated features.
- Found and fixed any of the user reported bugs i could.
- Continued with the various core updates to 4.14.
- Updated to my own toolchain, 7.1.1 hardfloat, cortex-A15 optimized (it is similiar enough to krait to give us an edge).
- I will update this if i think of anything else.
Sticky: Kernel base is now pretty much somewhere between 3.16-3.18, however I will keep the versioning at 3.4 for certain functions that depend on kernel_version conditionals. Wifi hotspot disconnect issue still persists, but i'd like to think that one day it will be solved...
Can be found in MachineX Rom by the awesome @Andycar found here: https://forum.xda-developers.com/ga...m-machinex-debloated-nogapps-s6-apps-t3573009
See my poorly formatted wiki for older updates:
https://github.com/robcore/machinex/wiki
-----------------------------------------------------------------------
LOGS
In Synapse, under 'LOGS AND PROFILES,' you will find a button that says ALL LOGS. Please press this button IMMEDIATELY after a bug appears that you would like to report, or after a boot if you get a kernel panic (RR).
From now on, without these logs present, I am no longer able to respond to the issues brought up by users.
FIXES
The following fixes involve sqlite and the "Setting Storage" application, also known as Settings Provider, or "com.android.providers.settings package" You will be working with a file named settings.db, and the 'system' table within.
Synapse Cancelled Fix: Get rid of the init.d scripts that are conflicting with UCI service startup. Also check the SuperSU section below...
Sound Fix: Either don't use an audio mod, or don't use Faux Sound Engine. That's all she wrote.
ScreenFlickerFix: Using an SQLITE DB Editor of your choice (from playstore), navigate to the "system" table and change values for "dim_screen" and "intelligent_screen_mode" to 0. *UPDATE* NOW AVAILABLE IN SYNAPSE UNDER THE "EXTRAS TAB"
ChargingTweak: Same as above but change "adaptive_fast_charging" to 0. This is only IF you are having issues which kernel driver-level fast charge. *UPDATE* NOW AVAILABLE IN SYNAPSE UNDER THE "EXTRAS TAB"
MASSIVE THANKYOU to @Andycar for making the above two fixes possible via Synapse!
SuperSU: I'm seeing a lot of permisison errors. Make sure, when using custom roms and kernels, that SuperSU is set to be as permissive as possible so you don't get knox blocked. Here are the crucial settings:
- ENABLE SU during boot
- DISABLE (untick) Mount namespaces separation
- Install SuperSU into /system
- ENABLE Trust System User
- Though I know many have security issues with the idea of allowing apps by default, doing so will make your experience way faster and provide you with less interuptions. At the very least I would set allow by default for Synapse.
These SU settings are kinda par for the course when it comes to android modding.

For those having gaming issues, try removing them if you have them or adding them if you don't:
debug.performance.tuning=1
persist.sys.ui.hw=1
This might solve some issues for some folks.
---------------------------------------------------------------------------
INSTALLATION NOTE: Your first boot will probably take longer than usual, because this kernel makes significant (but safe, and auto-backed-up) changes to your core operating system.
This kernel includes drivers that TW has been compatible with since JB (I checked),
but didn't update the kernel drivers for (the best example of this is Autosleep). That said, there are userspace controllers like thermald and mpdecision (a binary linked to kernel code)
that interfere with custom governors, hotplug drivers, etc, so I've made the decision to back them up in the kernel script, and have them disabled while using this kernel.
The UNINSTALLER restores everything to the state it was in before flashing machinex, which is why I so strongly emphasize its use.
PERFORMANCE AND POWER-SAVING
Regarding the age-old performance/battery-life settings questions floating around, I'm gonna go ahead and suggest the following website created by a very dedicated fella who started out with the exact line of questioning, and built a genius guide for users of custom kernels. Heck, it's useful for developers too.
His username here is @gsstudios and he is a recognized developer here on XDA. Deserves it too
http://androidmodguide.blogspot.ca/
and on XDA:
http://forum.xda-developers.com/general/general/ref-to-date-guide-cpu-governors-o-t3048957
I encourage you to rate that thread 5 stars, as it is the most comprehensive guide to kernel tunables you ever did see.
Note that I *probably* don't incorporate feature requests, as I have enough on my plate with bringing up the subsystems to a point where I can call this a stable release thread. Don't like it? YOU try backporting linux 3.9 scheduling code to a Samsung 3.4 base
On that note, if anyone here is savvy regarding kernel, C and (not "or") git development, I welcome coding partners because working with a team means better quality, better time management, and a better chance of incorporating fancy tweaks.
Cheers.
SYNAPSE:
Synapse has a default "warning" that comes up the first time you open it.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The initial warning is just a bug in the app because it's just been installed.
It's a design flaw in the app itself.
Synapse bases its stability check on whether the device is rebooted within 2 mins of being turned on.
Synapse does this on first boot for every single kernel that uses it,
because it has no previous internal boot settings to base its decision on,
and also because the app expects saved defaults when none have been established yet.
It is nothing to worry about.
Untick the option in settings called "stability check" going forward.
Breathe.
Does it work?
I'm on imperium kernel on Thor s7 rom, I was wondering if your kernel works with m919, tmo gs4, I was looking forward to trying out your rom.
Thank you

Hey Jeff,
The answer is...maybe/probably. I know that's probably not what you want to hear, but let me explain.
My device is actually an i337m (which is why i included it in the thread title), but I've been using the international kernels and roms without *major* issues ever since I've owned it. This is built from international sources, and it is running well on Albe's awesome 9.0 rom, so I imagine it will perform well for the ported/upgraded roms for our phones.
So if you've been using the international roms/kernels without problems, I see no reason why this wouldn't work for you other than the bugs/current issues listed in the op.

Everyone who uses this, feel free to provide feedback to help me assess what's needed for MarkTwo!
@robcore.
Im gonna try this to imperium rom v15.
So what is the best settings for more battery life ?
Playing clash of clans a few times a day browsing tapatalk and using youtube all day.
I want my device to run cool. Lol
Update:
Got a random reboot from the first initial setup.
==========
Will let it run for a couple of days with the preset default settings.
I will use my old 2600mah for now and later on swap my 7500mah once i get some good battery stats.

Msm sleeper is a pretty sold hotplug for battery. I've noticed power efficient workqueues tend to slow things down/eat battery. Honestly I would try out msm sleeper for battery savings. Just note that games+youtube by design will eat into battery life. I will add some more power conscious governors soon. Also the usual stuff, the power your screen brightness the better, and turning off vibration/haptic will help.

I'm using this Kernel now on my GT-I9505 with THOR S7 v1.5 and so far a stable Kernel for me, many settings and alot settings I had never seen before as I like, very good! Just one thing til yet, Trying to set "Hellsactive" as CPU governor causes a freeze and a full reboot. Otherwise Kernel seems stable, using "Stockdemand" CPU Governor now. Keep going your work!

You know what, the interactive-based governors gave me trouble for the longest time. But I have found the issues in a great patchset, and am working on a fix that should be ready in a couple of hours. Until then EVERYONE STICK TO ONDEMAND-BASED GOVS!!!!

I'm guessing interactive based gov? If so, see my post above, MarkTwo is coming tonight.

Dude thank YOU. I can't tell you how much I appreciate you and the others for testing this out and helping me iron out the remaining bugs, and being so understanding that "interactive based govs are broken" which is super embarrassing. Lol.

Update: simple gpu gov is snappy at stock settings and sooooo much better for battery consumption.
Also if memory serves me correctly, aren't you a cm kinda guy ; )

Nope havent touched anything
There was a failed message when i booted the synapse app.
Something link kernel image failed but not sure should have taken a screencapture and the log.
Either way its working now.

More into like AOSP rom but had to use Tw for camera/video
I just noticed something.
My display colors somewhat changed? I think in a good way. Lol
simple gpu gov in marktwo?

Well it's great to see you here man! Lol with screen colour I made some fixes and changes to sammy's mdnie code. Upon checking the code against their roms, it turns out they've never bothered to fix discrepancies between the values in settings and the driver itself! "Standard" and "dynamic" have been switched this whole time. Also "auto" has been a placebo all along, they have had the backend in place all along but never initialized it in the list of available screen modes. On that note, for even cooler stuff check out the "video_mode" scenario in synapse. It's AWFUL for battery life, but sharpens everything to a crisp. I'm pretty sure kcal helped with color too(?).
As for simple gpu gov, works just fine on MarkOne! Franco's simplification to it made it a freakin' powerhouse while being better for battery somehow.
Building MarkTwo as we speak, then I'll test it and it's out! I'm working on the gov settings in synapse while building too. The tunable settings are ticking me off.
