I've been running my CDMA GN unlocked and rooted for a couple weeks now, and I think I'm ready to jump into the world of non-stock ROMs and kernels. Of course, there's quite a few of them, and there's a ton of stuff in their descriptions that might not make a lot of sense. For instance, here's a sampling of various lines from "franco.kernel" that might as well be a foreign language to me:
Compiled with the optimized Mjolnir compiler with special cflags
.config tweaks to improve multitasking, responsiveness, battery etc
dirty_writeback values tweaked
Cgroup: speed up access to cgroupfs mounted entries in /proc/mounts
block: strict rq_affinity
TUN and CIFS modules added to /system/modules
3.2-rc7 RCUtree backport from imoseyon
I/O-less dirty throttling - backport from 3.2
Hotplug cpu1 is implemented somewhere else

So...first things first: do I need to understand any of this if I'm a user and not a dev, and if so where do I find it? If not, what are some good metrics to help me determine what ROM is closest to what I want? How will I know whether I need a kernel with a ROM or whether it could break something? Note that I'm not really asking for suggestions on specific ROMs or kernels here, since that's pretty much completely subjective. I'm just looking for resources on how and/or where to best educate myself without coming off as bothersome and clueless to the devs if or when I start asking questions.
You typically don't need to understand anything that you can't understand without looking it up. For you only need to read the things that are in plain english not computer speak. In the rom threads you really only need to find a rom that has features you like. None of the kernels out should break anything, and you should be fine just reading the things in Franco's thread such as "improved colors blah blah" if you do want to know something though feel free to PM me and I will try and help

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.***

***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?

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.

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.

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:

** Note: This kernel is end-of-life and will no more be maintained. There will be no LineageOS 15.1 or newer kernel be available anymore **
Hi all,
some of you know me from the Samsung devices area, where I provide my kernels already for more than two years to Galaxy S3 and Note 10.1 users for all sort of platforms (Samsung, Cyanogenmod, Omnirom etc.)
Please note:
I am not heading to have as many features as possible implemented, this is not my design goal. If you are more into that, move on to other, good existing kernels. If you are searching for a good mix of improvements and new functions while not sacrificing stability, you are welcome here (see below the history section for more info).
Compatibility
Important: This kernel is only meant to be compatible with official Cyanogenmod / CyanogenOS and nothing else.
So when the kernel does not run on custom rom XYZ, do not even bother me with it or ask hundred times in the thread for compatibility.
I could not care less about it !!
Important notes
1) When using new anykernel concept Boeffla-Kernel: Flash stock kernel of rom first !
2) Do NOT use TWRP's function to root your device after a clean rom flash!!! The installed supersu version is not up to date and may cause a bootloop with latest COS/CMs kernels !!!
3) Make sure you flash the correct kernel version, depending on whether you use cm11s stock or genuine cm11, COS13.0, COS12.1, COS12.1.1 or genuine CM13 !!!
Also note: You have to use Boeffla-Config app which I provide on my homepage to tweak the kernel. 3rd party apps will not be able to unleash the full power of the kernel.
Saying that, the Boeffla-Sound app in Play Store is not designed to work on the OPO, neither was it developed by me, hence it will never work on the OPO ever. Boeffla-Config is the way to go here !!!
Support
First read the FAQ section on the Homepage !!!
Click here to learn about all possible kernel settings in the config app.
Click here to learn about using the config app.
I will refuse to give support if you do any undervolting and experience freezes or hot reboots.
I will also not provide any support if you do not use Boeffla-Config app to tweak the kernel, other 3rd party tweaking apps are known (and intended) to cause issues.
I will refuse to give support if you have xposed framework installed and reporting any kind of weird issues. My opinion to xposed it quite clear: too powerful for >90% of the users that just mess up their system with it.
Otherwise, you can get in touch with me via the support e-mail address: [email protected]
Please provide kernel version, rom version, a detailed issue description and ideally supporting screenshots or log files.
Change logs
Change logs can be found at the first page of the kernel homepage:
www.boeffla.de
(you can also access them directly in Boeffla-Config V2 by pressing menu and selecting "change log...")

Presets supported in Boeffla-Config by kernel (Extreme power, power, normal, battery friendly and battery saving)
Google gcc 4.8 toolchain used for best stability
Always using latest Initramfs
Always based on latest OnePlus One kernel sources
Note: I do NOT upstream the kernel to higher Linux kernel versions anymore as this usually has zero benefit but likely introduces new issues + is a waste of effort in the end

History and design targets
Basically I created my first Boeffla-Kernel in 2012 as there was no kernel for the Samsung Galaxy S3 around that had exactly the mix of functionalities that I wanted. I wanted to have full flexibility in undervolting and charge rates for instance, but did not like the sharpness and/or brightness tweaks many kernels have implemented as per default.
Hence, I began to create my own kernel after a while, adding all the features I like. This is the result of my work, which in the end I decided to share with you. I hope you like it as much as I do.
The objective of this kernel is to have a kernel for daily use. It does not aim for best battery life, or best smoothness or best benchmark scores. Also it does not aim to have the broadest feature set available everywhere.
It aims more for a good mix of all, not sacrificing stability and functionality in the end.
And - most important: It aims to stay quite close to stock !!!
These design targets are also valid for the OnePlus kernel here!!!
This said, I will definitely NEVER implement:
things I do personally not need
things I do not like
things that are in any way dangerous
anything which is highly experimental
custom hotplugging algorithms
a CAF based kernel
anything that requires upstreaming of kernel parts to a higher kernel major version
So do not even ask for it if it falls into the listed categories. Everything else I am happy to check and decide.
And: I do not really care about benchmark numbers, they say almost nothing as long as something is not completely wrong. Important for me is the feel-good factor.
I am also not interested in gaming at all, so never expect a gamer kernel. It will just not happen...
Compatibility
To reiterate it again: Flash the correct kernel depending on whether you are on stock cm11s or genuine cm11 !!!
Configuration of the kernel
To tweak and configure the kernel, manually load and install the app "Boeffla-Config V2" from the downloads section on www.boeffla.de.
You need at least version 2.1.48 or higher for the OnePlus One Boeffla Kernels.

Hi,
oh yes, zzmoove is already in
Thanks to master @ZaneZam, who was working together with me in the past 2 weeks on that topic.
If you loved my kernel already on the S3, you will even love you have the same kind of "structure" around the kernel. Same config app, same comfort functions there etc etc.
So, ... enjoy
Andi
waaaaaa... my lord.... welcome .... missed u from S3....... so happy...
are we expecting eargasm again ???
Lol, how nice... many "old S3 chaps" here. Good to see you again guys

Not in my plans as I have only one device. So the same goes as long time ago for the S3 and n8000.
One device = only the "official" firmware. This is still my golden rule of thumb
If enough people help me to get a second device, it would change of course.

I know.
But I loose features, and like for a daily driver phone to stay on the official firmware the vendor provides. That is my concept for more than 3 years now and I was always good with it.
So, no intention to change.
The question from other side is (although it is OT): What does CM provide me which CM11s does not have?
I am not missing anything, thats my point
It is not about invites, but paying another 300 bucks is not possible for me this year anymore (spent around 15 k€ for relocations, my car got stolen in February and so on... was an expensive year for me).

No, of course not.
This is technically impossible. There are things in Samsung that do not exist on this hardware (e.g. big parts of boeffla-sound).
And vice versa.
And some are not needed as they are included here by default (e.g. touch wake etc).
If you look carefully at the feature list, you can spot the differences
Andi
Pretty sure you can get the kernel to work with AnyKernel, but of course, when you do this, YMMV. Since it's designed to work best with CM11s, it might perform worse on other ROMs (and then there comes the complaints, bugs, issues, etc.). Besides, I don't see any need for any other ROMs than CM11s. It gives you everything you need.
ive used that kernel until last week on my s3, it was by far the best.
(boeffla sound was great)
hoping for a cm11 version sooner or later for the 1+1 :victory:
I have used your kernel on my s3 for along time, it's awesome! Very happy to see your work on OPO.
Just ask one question, I'm using f2fs with ak kernel on my OPO now, so does this kernel support f2fs filesystem? Cuz i didn't find it on your feature list..
sorry for my english
Hi all,
some of you know me from the OnePlus One or the Samsung devices area, where I provide my kernels already for more than two years to Galaxy S5, S3 and Note 10.1 users for all sort of platforms (Samsung, Cyanogenmod, Omnirom etc.)
Finally I got an OnePlus Two a few weeks ago and decided to start a kernel also for this device.
Please note:
I am not heading to have as many features as possible implemented, this is not my design goal. If you are more into that, move on to other, good existing kernels. If you are searching for a good mix of improvements and new functions while not sacrificing stability, you are welcome here (see below the history section for more info).
Compatibility
Important: This kernel is only meant to be compatible with official OnePlus OOS and nothing else.
So when the kernel does not run on custom rom XYZ, do not even bother me with it or ask hundred times in the thread for compatibility.
I could not care less about it !!
Important notes
When using new anykernel concept Boeffla-Kernel: Flash stock kernel of rom first !
This kernel is ONLY compatible to OxygenOs stock 2.x or 3.x, nothing else !!!
If you are using a custom rom that bases on OxygenOs, it might work. However, if it does not work, do not expect me to do tweak to make the kernel running with your favorite rom. I would not do it - my one and only reference is OxygenOs stock.
It is not supposed to be compatible to LineageOS, CM, HydrogenOS etc.
Also note: You have to use Boeffla-Config app which I provide on my homepage to tweak the kernel. 3rd party apps will not be able to unleash the full power of the kernel.
Support
First read the FAQ section on the Homepage !!!
Click here to learn about all possible kernel settings in the config app (outdated at the moment).
Click here to learn about using the config app (outdated at the moment).
I will refuse to give support if you do any undervolting and experience freezes or hot reboots.
I will also not provide any support if you do not use Boeffla-Config app to tweak the kernel, other 3rd party tweaking apps are known (and intended) to cause issues.
I will refuse to give support if you have xposed framework installed and reporting any kind of weird issues. My opinion to xposed it quite clear: too powerful for >90% of the users that just mess up their system with it.
Otherwise, you can get in touch with me via the support e-mail address: [email protected]
Please provide kernel version, rom version, a detailed issue description and ideally supporting screenshots or log files.

History and design targets
Basically I created my first Boeffla-Kernel in 2012 as there was no kernel for the Samsung Galaxy S3 around that had exactly the mix of functionalities that I wanted. I wanted to have full flexibility in undervolting and charge rates for instance, but did not like the sharpness and/or brightness tweaks many kernels have implemented as per default.
Hence, I began to create my own kernel after a while, adding all the features I like. This is the result of my work, which in the end I decided to share with you. I hope you like it as much as I do.
The objective of this kernel is to have a kernel for daily use. It does not aim for best battery life, or best smoothness or best benchmark scores. Also it does not aim to have the broadest feature set available everywhere.
It aims more for a good mix of all, not sacrificing stability and functionality in the end.
And - most important: It aims to stay quite close to stock !!!
These design targets are also valid for the OnePlus kernel here!!!
This said, I will definitely NEVER implement:
things I do personally not need
things I do not like
things that are in any way dangerous
anything which is highly experimental
f2fs - it is known to cause various issues and compatibility problems
a CAF based kernel
anykernel method to use the ramdisk of the installed rom
anything that requires upstreaming of kernel parts to a higher kernel major version
So do not even ask for it if it falls into the listed categories. Everything else I am happy to check and decide.
And: I do not really care about benchmark numbers, they say almost nothing as long as something is not completely wrong. Important for me is the feel-good factor.
I am also not interested in gaming at all, so never expect a gamer kernel. It will just not happen...
Compatibility
To reiterate it again: Flash the kernel only if you are running a compatible rom !!!
Configuration of the kernel
To tweak and configure the kernel, manually load and install the app "Boeffla-Config V2" from the downloads section on www.boeffla.de.
You need at least version 2.2.03 or higher for the OnePlus Two Boeffla Kernels.

Also I want to thank xda user @magnamentis for the ongoing testing to iron out the stability issues of the first alphas. He was doing that always taking the risk to "ffy" his brand new OP2.
Special thanks as well to @ZaneZam to pinpoint the issue during my absence as I was on business trips most of the time in the past weeks.

*** You want my support? Then stick to my rules ***
Guys, I am receiving more and more completely useless support requests in different threads. Useless because people provide nothing to be able to help, not even the minimal possible information they could give.
Hence, I will now remind anyone again on the support guide lines stated here:
http://boeffla.de/index.php/support/support
Also you need to ensure you follow the installation guide lines incl. trouble-shooting stated here:
http://boeffla.de/index.php/support/installation-how-to
And to cut a long story short: If you do not at least provide what I request in the support guide lines, I will IGNORE YOUR REQUESTS IN FUTURE.
Straight and simple. I have enough of people wasting my time just because they are too lazy to write details.
Period.
Also as a reminder:
you use xposed? -> no support, everything is your own issue
you use a custom rom and not the official stock or CM one? -> good luck, you are on your own
you undervolt or overclock? -> have fun, but without my support
Sorry, this might sound harsh (and it is meant to sound harsh), but you cannot imagine about how crappy support requests can be. Stating something does not work is just not enough.
Please consider that!!!

Hi all,
kernel is now officially released in version 1.0-beta1.
Download link, as always, on the kernel homepage.
Some notes again:
Make sure you have latest Boeffla-Config app running -> 2.02.03 !!!
This is the very very very first kernel version, so expect bugs or issues
Please be nice when you have an issue, this OP2 kernel costed me more grey hairs already than all other kernels I ever built together
Let the fun begin.
Andi
Awesome!! As stated there's no gpu over clocking, however I don't play games on my phone, will I be able to downclock the gpu?
Finally will try and report if any bug welcome to the opt forums andi i was waiting for you (really)

Sure, just for expectation management: Do not expect too much for the start now.
The msm8994 soc development is quite fresh, as well as the device.
So I am not really far where I want to be in future in terms of features etc.
But stuff will come over the time, as it was with the OPO kernels and the S5, S3, Tab 10.1 kernels etc.

great... any possibility to add charging control to increase charging speed.. the only downside of this darn phone.. it feels like it takes for ever to charge... !!
I want to know how to disable CPU cores to save power. It was possible on my nexus 5. but on my nexus 6p and now on my htc 10, I'm not sure if it's possible. I read that it's would need a kernel rewrite or something along those lines.
So does anyone know how to do this? I'm running latest LeeDroid ROM if that helps. thanks :good:
That's what I also wanted to know about the 10.
I had the mind before and there I could run with only one core, if not needed the other three cores. But if I needed power, the 4 cores are running.
It would be great, if there is an option in kernel settings to run all the cores only if they are really needed.
So the 10 is only a battery eater... Especially with sense roms I don't come through the day without charging.
On CM 14 or AOSP the battery is much more better, but with better core management it would be famous.
anyone got any info on this?
less cores doesn't mean better battery life, look at u11, "octa-core" and getting better battery life than 10 and anything else. it's een like if you have less cores, the cores which are online have to do all the work and might end up with locked max freq which will result in heat and more drain. so just keep the core control like it is and maybe just underclock

It is possible to disable cores with the custom kernel, and I believe force them to remain off at boot, but the HTC 10 uses a big/little cluster CPU setup and disabling cores isn't how you want to conserve power in my humble opinion.
The HTC 10 and some other modern devices uses BIG.little core ARM processor technology.
So the hardware and software is optimized to use all the cores to chase the best battery life and performance. I'm guessing that unless it's very specific usage scenarios, if you manage to force disable the cores with a custom kernel, you'll see both performance and battery life drop.
I would highly recommend installing a custom kernel, and tweaking the kernel settings while letting the hardware make full use of the BIG.little cluster system for efficiency. For high performance, I'd recommend one of the sense based kernel's that uses the HTC PnP Manager system. Something like Flar's ElementalX or TBalden's cleanslate kernel.
For battery efficiency, since you're really wanting to customize things for the best efficiency and battery life, try out the Helix kernel, by zeroinfinity. It's using a technology to optimize control of the processor based on "EAS" technology. EAS stands for "Energy Aware Scheduling" and zeroinfinity has written his "Helix Engine" to control the power profiles and thus power consumption of different apps, and you can customize the profiles to put any other apps you have in the profiles you want them.
This was a very basic and non technical summary, you can find tons of info on the kernels in the OP of each kernel thread. I would recommend making a backup with TWRP and trying both ElementalX and Helix kernels and seeing what works best in your usage scenario, before you start trying to force disable cores.
Here's a quick article I found on google, I'm at work and only briefly skimmed it, so no promises it's any good, but you can google BIG.little procs on Android mobile devices to find more imformation. https://community.arm.com/processors/b/blog/posts/ten-things-to-know-about-big-little

was a good read, thanks! based on the quote from below from that website sounds like the little cores can drive the most battery savings the most .... which is my goal.
The LITTLE cores can be implemented to target lower leakage and a more moderate performance point, independently from the physical implementation of the big cores that are often tuned for higher frequency.

and seeing that you were a tester for helix htc 10 kernel, is it designed to with stock based ROM or just any magisk based ROMs? I did see that ASOP is not supported.

Stock based sense roms. I just use it with regular rooted builds of leedroid or viper. It works with magisk and has been built to be fully compatible, however I use it for my normal modded system rooted sense based rom with supersu. I don't use or set up magisk, I'm still kind of old school.
But if you were to use magisk, @ZeroInfinity is running magisk as his daily since the last several builds, and I don't believe it's got any bugs or anything that doesn't work in the magisk build. One of the other team members @p50kombi knows a lot about magisk if you need to know anything further, I just have very limited magisk knowledge I'm general.

Stock based sense roms. I just use it with regular rooted builds of leedroid or viper. It works with magisk and has been built to be fully compatible, however I use it for my normal modded system rooted sense based rom with supersu. I don't use or set up magisk, I'm still kind of old school.
But if you were to use magisk, @ZeroInfinity is running magisk as his daily since the last several builds, and I don't believe it's got any bugs or anything that doesn't work in the magisk build. One of the other team members @p50kombi knows a lot about magisk if you need to know anything further, I just have very limited magisk knowledge I'm general.

Great I also use supersu not magisk, probably same old school thing...also too tough getting things to play nice with magisk IMO. So for supersu do i just install v012 r1 systemless kernel and it should just work w/ leedoird? did you notice any functions on lee droid not working?
also do you underclock? recommend any kernel managers?

It's version 17, you'll download it from this post https://forum.xda-developers.com/showpost.php?p=73068312&postcount=1216 , sorry that link you had shouldn't be there, but systemless is the magisk version but now there's only one version, and the Aroma installer will let you choose the normal non-magisk version.
In the installer, there's a question that asks about installing custom scripts, I use the @ZeroInfinity script, the one from @roger81 and @TotallyAnxious are good too so you can't really go wrong, but I recommend starting with zero's, and you can reflash to experiment once you get going good with it. Rogers is great for battery life but his is a little more custom and extreme, which is why I'd start.
I use EXKM kernel manager, but I really recommend not changing many settings at first. Definitely leave the governor default with this kernel. I would run it like it comes out of the box, and see how your apps and battery life goes, and if you have apps causing a lot of drainage, maybe add them to the helix engine profiles before you start changing clock speeds.
You'll notice with EXKM the core frequencies reported in real time will look different from how it looks with a stock based kernel, but don't let that scare you.
My only other recommendation is if you use any other power saving apps like greenify or doze (I don't use any of them personally but some do) I would first get used to the kernel without them, so you kind of have a better idea of baseline.

Bonus points for being the least confusing AROMA installer I have used! and I used zero's as well. thanks for all your help! and one last thing.. isn't doze built into android nougat? or am I highly misinformed.

It is you're correct, but there's a lot of "super doze" and dozingest doze around" sort of mods and tweaks people use, it's the extra modified stuff I would avoid for now, until baseline is established. However once you get things ironed out, @RogerF81 (if I spelled that Right) has tons of good info on further tweaking. He once tweaked his battery life to something like 7 or 8 hours screen on time with the Helix EAS kernel. That's just showing off.
Glad you like the Aroma installer, it nearly killed the poor dev trying to get it set up when he first started implementing it, he still probably throws keyboards if I ask for a black theme lol.
