Building Falcon Kernel
If you'd like to build Falcon Kernel for yourself you can do so very easily.
You will need a Linux build environment setup. I won't include this but you can read Google's instructions here.
Getting the source
Visit Falcon Kernel kit repo over at: https://github.com/harrynowl/falcon_gemini_2.0
Create a fork of this repository that you can maintain for yourself by pressing the fork button towards the top right.
Now you will need to create a local copy of Falcon Kernel on your build environment. On github click the green clone button to get the clone URL.
Open the terminal and type:
git clone <clone url> -b <branch> <dir>
e.g.
Code:
git clone https://github.com/harrynowl/falcon_gemini_2.0.git -b Nougat mykernel
Now cd into the directory you just cloned the kernel into
Code:
cd mykernel
Building the kernel
Falcon Kernel source code contains two fairly basic scripts to download the toolchain and also run a build.
Start by typing
Code:
./toolchain.sh
When that is done, I'd suggest running through a build to make sure everything is OK.
Code:
./build.sh
Changing the kernel
You can start by changing the Kernel name. Navigate to falcon_gemini_defconfig in arch/arm64/configs and change CONFIG_LOCALVERSION="<name>" to whatever you would like to call the Kernel.
You can now look through other kernel commits and see features you want, and cherry pick their changes.
You can update your changes to github by commiting with git commit and then git push.
This isn't the be-all and end-all of Kernel building, but it's a start.

I installed it on AICP and I got a bootloop. I guess it's only compatible with CyanogenMOD 13 for the moment, and not other ROMs based in cm?

AICP uses a different Ramdisk than this kernel has, so it wont boot.
This will be the same with DU and AOSP.
Let me understand the 32 gb hardware is only limited by software ? the components are the same? i know about de cpu but the other components no

The LPDDR4 frequency is still lower than the 64/128GB version(s). But my testers earlier could confirm this seems to unlock the full potential of the Snapdragon 820 for 32GB phones :good:

Andromeda Kernel
Supported: SM-N910F & SM-N910V
Do not try to flash this on ANY other variant than the N910F (Snapdragon, European)! It might work, but it can fail and end in a bootloop! Testers for SM-N910G wanted!

Frequently asked Questions (FAQ)
Or Questions and answers, since this thread is new.
Q: Can this be flashed on the Exynos Note 4?
A: No, by no means. The Exynos model is completely incompatible, sorry.
Q: And what about other Snapdragon versions?
A: I can't advise to do that, it's untested and might not work. If you know how to handle bootloops and can remove my kernel if it doesn't boot, then you can always try it and tell me how it went. More variants would be awesome.
Q: Yikes, this kernel is too close to stock! What about more features?
A: More features will be included, please check the changelog preview. You can also request features and track the progress. I will make a section on this thread to display the feature request and write if I look at them, make them or - and that might happen - reject them.
- To be updated..
Known Issues / Fixes
Bootloop if you have Viper4Android installed and flashed Andromeda over it
Fix: Uninstall Viper, install Andromeda and then reinstall.
If this issue persists in my future builds, then I'll add an automated script to remove Viper4Android upon installation of the kernel.

Hi, yes of course you can! We are actually working on deeper and more exclusive support for SimpleRom too. Stay tuned for version 2.1, it will be awesome
My kernel is much closer to the stock base, so you might get some more performance squeezed out - especially if you select Intelliactive as your governor - but at the cost of battery. I'm still not so big on features, the last couple of days my compiler decided to give me a hard time :crying:
Only 910F for now though!

I'm not part of their Team, but Pafcholini is teaching me Don't worry, this kernel is not a clone of Nadia. My newest and upcoming build is as fluent as the last one and the batterylife is holding up a ton better too. No compromises on either side, thats my motto!

Andromeda Stable 1.0 released!
Good evening everyone,
it took me a while, but I present you the first Stable build of Andromeda!
Changelog
- FauxSound 3.6 fully integrated
- IntelliPlug 4.0
- Enhancements and battery optimizations (mainly centered around powersuspend and adaptations to the default interactive governor)
- Renamed the Kernel in the settings, the last one was a disaster
- 57% Support with KControl currently (Playstore App)
Click to expand...
Click to collapse
About the Overclocking and Synapse...
I originally intended to include both in this build, but it will still need much more time and work and I didn't want to keep you away from the great upgrades I made in this version, so those two goodies will come later. I can highly recommend trying TricksterMod and KControl, both from the PlayStore.
And a very special announcement...
Perhaps the biggest change is that I recently joined "Team Simple - Simply Awesome" cool and will contribute an adapted version of the Andromeda kernel to SimpleRom, starting with the very close release of it's 2.1 Build. We planned something special - FauxSound is only the cherry on the Audiophile package inbuilt, so be very excited for whats coming up and be sure to try SimpleRom, especially the upcoming 2.1 version!
Oh, btw. I will also open a thread for the SimpleKernel once the Rom is released, to provide an optimized yet very close to stock experience! And there are also plans for an Exynos Build (the N910C), but I need some help with the Exy, so if anyone could lend me a hand, it would be highly appreciated! Now I understand why most devs settle for the Snapdragon..

Wait. Anybody tried the kernel on cm-12.1 and faced same issue of camera FC?
I'm asking this because I have merged some extra CAF stuff only for caf based/cm-12.1 based ROM's not stock, so stock users may face some issues(Didn't know it was related to camera). I'll compile new kernel without CAF for stock users too.

hey, one more thing, mp3 player doesnt play too, oxy 2.0.2, using phonograph, tried again with solid explorer to no avail.
youtube works though.
I was on 2.0.1 and the camera seemed to be fine will try again on 2.0.2 and provide logs if I can

Phone doesn't boot with this Kernel.

Hi oneplus2 people!
This is my modified kernel with some kernel optimizations and some compiler optimizations.
The goal of abyss is to achieve improved performance/battery without the cost of stability.
I will not be overhauling this project with changes that are not logical to add.
This kernel should work on the latest 7.x.x roms like CyanogenMod.
It might work on other roms, but there will be little support for them.
How does one achieve this?
- build kernel with an optimized toolchain
- use compiler optimization flags (experimental)
- remove redundant code
- improve existing code with more efficient code
- etc. (most are not so easy to explain)
This kernel is built with mdalexca's latest UBER GCC 4.9.
Is there actually a performance improvement?
With all the changes added up, there should be. Whether or not one notices the difference is another thing.
For those interested in how the kernel optimizations will benefit/work, please look at my github source and read the commit messages.
For those interested in how the compiler optimizations/hacks will benefit/work, please look at this article.

Frequently Asked Questions:
Is this a custom kernel?
I was asked this question once, and it posed as a real good question. I do not consider abyss to be a "custom kernel" per se, but more so as a modified kernel. The patches and features that go into this kernel do not make it customizable. What they do is improve what has already been implemented. It is like swapping a car's engine for a better one rather than just adding LED flooring lights and fancy car mats.
Can you add [this] and [that] feature?
Something I pride myself with this kernel is that it does not have a bunch of random, useless features or patches mashed into it. Everything put into this kernel is thought out and tested. I see a lot of works being made popular because it has [this] and [that] feature when really, it's nothing revolutionary. As a matter of fact, most things added to any kernel will not make it 5x better than any other kernel. Most of the time, simple is better; and in this case it definitely is!
For me
Thanks! I'll give it a go.
Giving it a go
Yess! Been waiting for this ever since i saw your OP2 repo!
Does this kernel install on a f2fs formatted system?

You can thank @dsst22 for helping with testing, or else you would have waited a very long time :silly:

I have not made any file system changes to the kernel. If the stock CM kernel supports, then this one will too.
Is kcal support present..??

You can probably see how much I've grown as a developer since then too :angel:
Works on a f2fs filesystem based rom. Testing it now...
Edit: No obvious bugs at the moment. Is it possible to implement some sort of charging control. The USB charging speed is super slow (on both this kernel and stock CM kernel).

Nice!! thank you!!
Pretty smooth haven't found any bugs. Love the simplicity.
I can't imagine what it would be like with a little over clock.

I trust the engineers that designed the chip to choose a safe maximum clock speed. Here's a pretty good article on the risks vs benefits, which outline some strong points.
But, if I were to add it, I would set the max value at boot to stay as stock values; so I'll leave it up to @dsst22 to decide.
I'll try this out for you dude. Impressive what you've done.
EAS kernel for op2

I have no intentions to support CAF ROMs. I made this kernel compatible with only lineageOS. If you're using it on another ROM that's your problem
Both of these features work fine on lineageOS

Wasn't aware that this kernel is for lineage because wasn't mentioned
Anyways nice work this was needed since long

I've always developed for lineage so I thought people kinda knew
Will add to the OP

None exist for sd810
I'm on official Nightly, will this have any effect or it requires a change in ROM?
A small fix is required in the device tree. Unfortunately right now there are no ROMs with this fix
You can flash it, it will work fine but I recommend switching to my unofficial builds once I add all the patches to my ROM
In fact there's a lot of work to be done on the ROM. I'll eventually do that too but for now we have a stable EAS kernel
will you continue develope hmp version or only this version?

That needs ROM specific support
It is impossible to add an sepolicy for each ROM
@_LLJY I'm not going to add anything to the kernel that modifies the ROM
The msm8994 does not have an optimal energy configuration for EAS besides anything that was derived from Bullhead which is far different.
I'd stick with HMP anyway. You can still make use of most of the benefits of EAS (except for scaling based off of power of course) to a similar dynamic.
Now, you are welcome to experiment but understand that optimum values are not one size fits all

Well that's why there are 2 kernels
People can pick whatever suits them best
As for EAS it's still smooth without the HAL but a proper energy model is unavailable

Yes, it's okay. But it would be better if you wait the next build cause I'm adding f2fs support

It might be an idea not to include Magisk. Not everyone wants root.
You can add suport to ntfs sd?
