Development Goals:
- stability
- energy savings due to more efficient algorithms (whether theoretical or not is unimportant)
- strictly no overclocking unless approved by the manufacturer or my source base integrates it (also, even if my source base integrates it, expect no support for it)
- no undervolting as well unless the manufacturer approves it since it's relatively pointless IMHO...
- all improvements should require MINIMAL user interaction (e.g. you don't need to do anything except flash the kernel or at the very least use SetCPU or the like to set fixed options)
- stability

In theory, whether it's deodexed or not won't make a difference... I only have official ROM to test... also, is your panel JDI or AUO?

* In other words: It is your choice to use this software,
* I am not responsible for any damage or problems!
FEATURES:
based on HTC source code

INSTALLATION
1. Install zip from TWRP Recovery
2. Reboot!
S-OFF recommended for easy installation
S-ON:
The installer includes a method to flash the boot.img for S-ON devices;
however, some people still have difficulties. If it doesn't work:
1. extract boot.img from the zip, reboot to bootloader and do:
fastboot flash boot boot.img
2. you must still run the installer to get the correct modules for this kernel
First boot will take a while. Let it load all the way, then let it settle in for a few minutes, then reboot again.

When you say that "there is no more r/w protection", does it mean that we can flash hboot or stuff like that in system, and changes will be permanently?

Flashing & Tweaking Instructions (Follow this very carefully!!!):
- Place the zip at the root of your phone's internal storage (This is very important! If you flash the zip from a subfolder, you'll be left without wi-fi!!!)
- Reboot into recovery
- Flash the zip
(Another way: Reboot into recovery without copying the zip, and flash it via adb sideload)
- (Optional) Wipe cache and/or ART cache
- Reboot and have fun!
Coming from another kernel? Then I suggest you to (at least!!!) dirty flash your stock rom and kernel in order to avoid any issues!
Wanna tweak it? Use Kernel Adiutor! (I do NOT support Synapse!!!)

Current Stable Version: R3
Stable Release Date: 2016-07-07
Created 2015-09-07
Last Updated 2016-07-09
F.A.Q. (Read this before crying!!!!)
Q: Why did you develop this kernel?
A: Read the OP.
Q: ERMAHGERD DIS KERNEL SUCKZ, MAH BATTERY IS DEAD IN 30 MINS, PLZ HALP!
A: When I created this kernel, I never had the intention to have it decrease battery life. So before / instead of complaining, go check your f***ing wakelocks and fix them! The kernel isn't responsible for this, your apps and/or services are.
Q: Will this kernel work on AOSP/CM12.1/CM13 ROMs?
A: Go here for that.
Q: Will this kernel work on the GPE ROM?
A: Yes. And it'll also allow you to use this ROM without having to format /data to ext4.
Q: How do I report bugs?
A: If you wanna report a bug, then grab your kernel log - either by pulling /proc/last_kmsg (in case of a random reboot / kernel panic or oops) or copying the output of "dmesg" via shell - and paste it at pastie.org and link it in your post (or save it to a text file and attach it to your post). Don't bother getting logcats, they don't apply for kernel debugging purposes.
Q: How do I flash this?
A: I suggest you scroll up and read the OP. The instructions are there.
Q: How do I tweak this kernel?
A: Download Kernel Adiutor from the Play Store and have fun. For Synapse, scroll up and read the OP first.
Q: This kid is such a n00b!
A: Oh well then, why don't you go work on a kernel yourself, instead of criticizing my work and, by doing so, wasting your time?

Kaminari SuperLite (previously "Optimized Stock Kernel")
Since KaminariLite has been discontinued, and Kaminari has become cleaner regarding features, I've been working on a version closer to the stock kernel, only more optimized.
Enter Kaminari SuperLite!
Diferences between this & the stock kernel:
- Compiled using generic Linaro 5.3 toolchain
- Bumped to Linux version 3.4.112
- Compiled with -O3 and misc optimization flags flags (Same as Kaminari)
- Most if not all of Kaminari's optimizations have been applied
- All governors except Interactive removed
- Supports both stock and GPE roms, regardless of filesystem (f2fs or ext4) used on /data
- Adds init.d support
- Default ZRAM size changed to 400MB
Click to expand...
Click to collapse
Differences between this & Kaminari:
- All governors except Interactive removed
- AutoSMP removed
- All TCP congestion algorithms except Westwood and Reno removed
- Additional I/O schedulers (zen, vr, sio, fiops, bfq) removed
- All non-essential features (FauxSound, Kcal, Dt2w...) have been removed
- Stock PowerHAL has been re-enabled
- Compressed using LZO (Kaminari uses XZ)

So it is only for stock 5.1 right?
Edit: Working smoothly on stock 5.1
Keep it up.
Working great on XT1031 with stock 5.1. Nice job!

No, no plans for aosp/cm support yet - mainly because of my limited knowledge. But i'll consider making a version supporting these two
New build in the works! Just trying to fix a bug where all CPU cores stay online (needless to say that this causes a gigantic battery drain)
New build up!
https://www.androidfilehost.com/?fid=24052804347811341
https://www.androidfilehost.com/?fid=24052804347811344 - "Mori" version - with S2W/DT2W
Changelog here.
I'm getting an update binary execution error with TWRP, with both new builds. I tried disabling the device check in the anykernel.sh but no go. Also, I noticed in the init.kaminari.rc file in the zip, there is a typo in the power mode lines. It has 2 lines for cpu2 and none for cpu3. I just noticed the same thing with Optimus V41 Prime earlier today.

The previous zips i made here worked fine (i flash them through adb sideload). And i just fixed the init.kaminari.sh. Plus i've fixed s2w/s2s in the Mori version (dt2w is still partly broken though).
New build up!
Version: 0.96b
Download: Regular Version | "Mori" Version (DT2W)
Changelog here, but for those who don't wanna go there:
- Fixed s2w (dt2w halfscreen is still broken)
- Fixed derp in init.kaminari.sh
GPE users, please test my builds if you can / feel courageous enough to do it
I give up, except for the first build, they won't flash in recovery for me.

I'll upload a zip without anykernel later. Btw, which version of twrp are you on? And do you have sufficient space in /system? Because this kernel pushes modules to it. I'm on twrp 2.8.7.0 + a modified stock rom, and i've had zero flashing errors so far
For those who are having problems with anykernel, i've uploaded special flashable zips without it.
Version is still 0.96b.

Version 096b flashed without any problems.
Just put the zip in the root of internal storage.
cool everything is just superb @kingkaminari hope you keep updating this kernel
Hi Huawei P9 people!
This is my modified kernel with some kernel optimizations and some compiler optimizations.
The goal of abyss-caf is to compromise stability and improved performance.
I will not be overhauling this project with changes that are not logical to add.
This kernel should work on all stock based roms; there is a separate version for NCS rom.
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
- reduce/increase speed of timers (depends on what type of function)
- etc. (most are not easy to explain)
This kernel is built with Linaro GCC 4.9.4 that is optimized for ARM64 devices.
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.
Personally, I do feel the performance difference. It is easier to notice the difference with lower level specs.
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 to abyss?
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 well 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!
Awesome, will stay tune about new releases, will try the kernel later.
Just for clarify, kernel works in any P9 or just for L09 or L19?

There's no reason that it wouldn't work, but there's always that slight chance. Pretty sure you'll be fine

I have a question though.
Will it conflict with the L Speed app I'm currently using?
And to finish off my day (the start of many of yours), here is my 2nd release for y'all.
Code:
- optimized square root algorithm (3x faster)
- added BFQ io scheduler (now default)
- backported random from Linux 4.2+ (better entropy, better performance)
- utilize power efficient workqueues all over the kernel
- port quickwakeup driver for hisi from moto
- optimized lib patches
- optimized arm64 lib patches
- disabled gentle_fair_sleepers for better UX
- enhanced multicore decision making

Not sure why it would, what tweaks do you have turned on? It should be good to go, I highly doubt anything can go wrong with any sort of non-kernel related tweaks.
this is great news! You have my thanks
For anyone on NCS rom, the kernel will not boot for you. Please test this build out. I will be looking into using an AnyKernel 2.0 flash method for TWRP users so that we don't run into conflicts like these in the future.

Not only my rom, its for all recommended if root is installed.
This is ****ing awesome kwoktopus, so excited to try your work (tomorrow). Finally some more new development for the great P9.
Thanks kwoktopus !

Not exactly sure. If fRomFuture has ramdisk modifications then probably not, I'll have to make a separate version for it. If you would like to try, download both versions of the kernel and try.

If it doesn't work even through fastboot, try flashing my test versions.I will upload it with changes for fRomFuture that may work. Stay posted
edit: i am running low on bandwidth from all the source downloading lately, can someone upload the boot.img from the latest fRomFuture build
Uh...probably super obvious, but do you need unlocked BL and/or root in order to flash the kernel? Ta.

Hi.
I've tried the kernel clean on the NCS ROM 1.2.
Unfortunately, the camera failed to launch and I noticed jerkiness in response.
NxKernel
r4
Yeah, jet another kernel for the falcon!
Why? You might ask and you are right.
I have been experimenting with kernel features, fixes and (alleged) improvements and always tried to create a kernel which I would be happy to use every day on my device. You know the usual stuff: long lasting battery with lag-free performance... It's not easy at all I have to tell. I am not a developer but know my way around Git and programming and researched a lot of sources on the internet looking for kernel stuff. Some patches offer improvements in speed and response time etc, but in reality, many of them do more harm than good when it comes to real-life praxis. In the end, I had a great collection of fixes and patches which I tried (nearly) one-by-one examining the gains and losses of 'em.
All the credits go to the developers of the features - and a little of it to me for putting them together and bringing them to the Moto G.

I suggest Kernel Adiutor to edit the kernel settings. See attached screenshots for the details. The settings that cannot be seen on the pictures are untouched.
I've attached the two json files to import for the two custom controls in Kernel Adiutor, bluedroid_wakelock and USB_fast_charge. To be able to import directly just change the extensions to json.
*For CM13 only! Causes bootloop on CM14 for now.*
Also attached the frandom enabler script (20frandom) that is to be placed in system/etc/init.d wit the permission 0755. Make sure you remove the txt extension first!
Sorry for the extension messing, xda does not allow to upload json files or files without extension... I might move the files to my file host soon.
CPU governor tunables
*to be updated for CM14*
Optimized governor tunables based on soniCron's superb guide. It works with interactive and intelliactive as well and scales fine with overclocking enabled and disabled too.
Basically, it uses 4 optimal frequencies: 300MHz, 998MHz, 1190MHz and 1593MHz if OC enabled. It prevents the CPU jumping a lot between frequencies that do not provide enough performance for a given task. I managed to get 4-5 hours of screen on time with these settings.
Tunables are as following:
Code:
above_hispeed_delay: 20000 998400:60000
boost: 0
boostpulse_duration: 80000
go_hispeed_load: 75
hispeed_freq: 998400
io_is_busy: 1
min_sample_time: 40000
sampling_down_factor: 0
sync_freq: 0

timer_rate: 25000
timer_slack: 80000
two_phase_freq: 998400,998400,998400,998400

No, it doesn't. I haven't really examined this feature as I use only one ROM on my phone. But I might add it in the future if it is requested.

Use Flashify
It has the option to backup the current kernel and can also flash imgs, zips and stuff.
Good to see another kernel available for our old (but seemingly immortal?) phone. Best of luck to you!
Like Kamin4ri said thanks for the kernel i really hope that moto g be immortal best phone that i used for sure, good enough for what i need.
Would be great if it has dt2w...

I did apply some of the settings from the pictures. I chose different scheduler and network TCP algorithm.
I do not have the paid version of Kernel Adiuitor, so I was not able to use the .json files.

Use a mod, kernel adiutor is open source
Hi guys,
I know that this forum is not widely used by ZTE Axon 7 Mini owners, but I still want to share my work the kernel used by the stock firmware.
Most of the parts were of course already based on the work of others, so I will give credits at the end of this thread of course.
Pre-requisites:
Unlocked bootloader
TWRP flashed
Knowledge you do this all at your own risk! I tested this kernel with my EU model, so I don't know if this will work on the US models, too.
Features:
- Based on latest kernel source shared by ZTE (ZTE B2017G Nougat(7.1.1) Kernel(3.10.84))
- Built with GCC 4.9 toolchain
- UC to 499MHz for BIG and 403 MHz for LITTLE (thanks to @flar2)
- OC to 1651 for BIG (again @flar2)
- Additional governors: yankactive, blu-active, impulse
- Additional IO schedulers: Sioplus, Zen, FIOPS. Tweaked Row is set as default
- Additional TCP congestion algorithms with westwood being the default one
- Approx. 30% faster due to CRC calculation and auditing disabling
- Sweep2Sleep on the navigation bar
- frandom RNG
- Sound Control by @flar2
- ZRAM using LZ4 optimized for ARM by default
- Optimized power management driver by @Yank555
- Native exFAT support without needing fuse @dorimanx)
- KCAL
- Vibration control
- uses higher power CPUs to boot (got roughly 3s faster boot time)
- Dynamic Fsync
- Gentle Fair sleepers can be toggled via sysfs and Kernel Adiutor
- Smaller tweaks
To do:
- Switch toolchain
- Remove "dirty" from the kernel name Apparently I need to push all changes to github before compiling(or recompiling the same kernel as soon as I pushed everything)
- Set the phone to accept the lower frequencies without having to set this up in Kernel adiutor
- Alter interactive governor to use full frequency range
- Add D2TS for screen and fingerprint sensor, S2W
- Wakelock reductions
- Maybe BLX, KCAL (even though I don't get the point to implement it) I was curious and did it now, looks nice
- LED and vibration control
- Switch hotplugging mechanism to Lazyplug, hotplugging is not that energy efficient anymore
See the attached picture regarding the CPU stats when using yankactive for example
Credits go to:
@Lord Boeffla @flar2 @dorimanx @Yank555
Unfortunately I didn't give proper credits on my github, I want everyone to know, that none of the features were designed and written by myself, just adapted to work on our phones!

I wouldn't exclude this, but as I am running on stock, I can't confirm or deny...
You could make a backup of your boot and flash it and see what happens, worst thing is that you need to reboot to recovery and restore your backup

You will need to try and see.
It uses anykernel which is good. But aokp and lineage are on android 7.1.2 while stock is on android 7.1.1. There was at least one kernel api change that may cause problems. But I'm not sure.
I'm assuming this package has the wlan module also...?

You mean the prima wifi stuff I have seen in you github? Honestly I didn't feel the need...does it improve the wifi experience or is it just for making it compatible with LineageOS?
No, I mean the kernel module for wifi, /system/lib/modules/pronto/pronto_wlan.ko. If that doesn't match your kernel, it won't load and you won't have wifi.
Note stock has a handful of other kernel modules, but I don't think any of them are needed Most look like they are for testing.

Oh, ok...pronto driver is built into the kernel though, all other modules are really for debugging and testing as far as I could gather, so they are not included (and the phone works fine)
@Askael: As for a custom kernel for Lineage/AOKP etc: as I won't have these OS's on my phone I use as my daily driver, I can of course create one, but it is always published as untested, so there is no point IMHO.
