Another kernel called Franken Kernel, also working on the pixel 4

Tested and working, thank you. Pixel 4 XL

Yea working gravy so far

If there is anyone who is wanting to improve battery, this improved mine. There may have been a problem app on my phone but now my phone actually goes to deep sleep now where it wouldn't before. So give it a try.

So far we have Kirisakura Kernel , Franken Kernel, ElementX Kernel (can get through the EXKM app, may have other source)
I've tried Kiri and Franken, both running good on my device, thank the dev's who made them

which of these improve battery life?

thanks for the heads up! kernel works great on my 4

oh, ok.
then I dunno, pm me an external link for that ? i really want to try change the kernel, but don't want to mess up the device, i could google it but preffer a recommendation of a tutorial by someone who understands more about it than i dunno.
anyway, thanks.
Hello, your kernel is very good, very fluid and good battery consumption in CM13, it would be possible in the future to add support KCAL?, can change the saturation, contrast, etc., thank you for your work.

Great kernel. Has improved battery life quite a bit !
Thanks!! Testing on CM13... Looks good
Good battery consumption.

Great kernel so far, thanks for making a custom kernel for 6.0, I've been waiting for one.
Would it be possible for you to add support for DriveDroid to your kernel?

Your kernel its a dream hahahaha I was waiting for a kernel with fauxsound since I've bought this phone. So, first of all, thank you very much for your kernel and we appreciate your work and your time spent with this kernel. But lets get to the facts:
1) In RR 5.6.0 your kernel cause bootloop;
2) In CM13 (specifically 2015-12-12 build) I had a lot of random reboots and the sound (specifically Play Music and Deezer) sometimes was cracking or just not played;
3) In CrDroid I had the same thing in CM13 but the rom has some serious bugs, so we don't count it;
4) In Nexus Experience 10.0.4 I just had ONE random reboot (take note: the first boot, so lets blame the instability of the rom) and, since then, my phone is working completely perfect.
5) With kernel auditor all of my preferences are saved and sticked after a reboot (in Nexus Experience 10.0.4)
Note: All of the Roms was fresh installed, wiped everything (including internal storage) then installed ROM->GAPPS (NX GApps in Nexus Experience and OpenGApps in the other roms)->KERNEL
Maybe with some work in your kernel and in the newer roms, this phone will gain some fresh air!
Thank you again!
Ps.: not an american guy, so please, I'm sorry for any english mistake

gpl | abyss kernel 5.20 | cm-14.x/cm-13.x

Hi falcon 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 (and maybe 6.x.x) roms like CyanogenMod and any other AOSP based 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)
Built with Linaro GCC 4.9 optimized for Cortex A7 with vfpv4 technology
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 like ours.
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.

Asking for ETA's won't be necessary because I use this kernel as my daily driver.
I do not mind if there's some non-development/off-topic discussion here, just no discussion about other works that is nowhere near related to mine.
Also, please refrain from comparing works here; it really kills the spirit of development. Go do that in some other thread.

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!
Main Patches and Features:
- intelliplug (default hotplug)
- intelliactive governor
- KCAL Control Driver
- kexec hardboot patch for Multirom
- USB Force Fast Charge patch
- Abyss Optimizations (compiler)
- disabled debugging for more performance throughout
- lots of patches for better performance here and there... too many to list
How to install:
Download kernel from Basketbuild
Boot into TWRP recovery
(If you're coming from a different kernel, dirty flash current ROM)
Flash kernel zip
Reboot
Nice job bro ! [emoji3]
Thank you for this awesome kernel [emoji6]

Sorry, I won't be adding underclocking to this kernel. There really isn't much of a need for underclocking a phone. In the long run, battery consumption will not be changed, maybe only at the slightest.
Also, the more frequencies added, the slower a CPU governor works. Most governors run calculations based on cpu load, checking whether or not it needs to move up or down a frequency step. By adding more steps, the cpu will throttle slower.
Just updated the kernel with frandom support. Also added some ramdisk modifications to support it.
More entropy == better performance.

AOSPA [CAF] for Nexus 5

Hello,
As some of you already notice I'm working on AOSPA 7.1.x for Nexus 5. When this project becomes stable AOSPA Team will consider about supporting it officially with me as maintainer of course.
So, I will share with you, my progress so far.
To-do List:
Fix audio effects problem
Rework device repo [need to cleanup]
Fix camera not saving photos
Device specific features:
Switch from mpdecision to autosmp (better battery life)
cpu-boost optimizations
implement task's adj rbtree (LMK improvement)
disabled cpu retention (hh bugfix)
vsync workaround (hh bugfix)
This looks very promising!
this is CAF? can i instal custom kernel like franco kernel?

It's caf based like LineageOS. But no, you can't install franco kernel. only the ones who supports caf roms.
YES, YES! It looks really tempting. Right now, a CAF base is much better for the Nexus 5 than an Aosp one. It's very nice to see something new based on CAF. Hope you will continue this project. Thanks and good luck.
I need someone who has Nexus 5 as second device to test and generate logs when I need as I'm using my n5 as main phone and have to backup and restore every single time.

I just got my 6P screen replaced today so my N5 is once again a backup. I know how to pull logs. If you need a tester I'm all in, send me a PM.
A tester here, as soon as it's ready.
Can't wait :good: good job :highfive:
I've been testing this for Marco during the past 2 weeks and everything works great. You guys have a reason to be excited and I know you won't be disappointed once it is released, which should be soon. I want to thank Marco for letting me be a part of his team and I praise all the hard work he has put into the ROM so it runs perfectly on our device.
I also want to test it, has someone have the latest build link? PM me, thanks

Hey! I read in the Dark ROM CAF threads that a CAF ROM won't work if the screen is replaced by a non-OEM screen. Since PA is based off CAF now, I suppose it will be true for PA too? Can anyone confirm and is yes, is there a workaround or something?

Yes. The fact is true.
Do we need to flash CAF recovery before installing this caf based rom ?
Thanks for all the hard work you guys, this rom has been one of the bests in the history of custom roms and this is a great comeback.
Is it going to be released this week? once again thanks, can't even wait!

Rom + Kernel Combo

Hello Folks...
Motive behind creating this thread is just to let know the new comers / OP5 users of this forum the most preferred / Loved ROM + Kernel combo..
I know there is no such thing called Best ROM , Kernel but just to make life easier for all of us.
Hope this thread helps all the devs from unnecessary questions in their threads like, hows this rom ? hows the battery backup. etc..
So, Please feel free to share your "Preferred" ROM + Kernel combo with some Pros and cons you faced and also some info on the battery backup.
Mods : Please feel free to delete this thread if not useful.

I don't have the device yet (shipment still pending -_-), but currently, I have a Google Pixel XL and I am running PureNexus with EX Kernel.
Once I get the device, I'm going to either install a ROM I find that is closest to PureNexus in terms of features and stability, or RR, as that seems to be one of the more popular ROM options out there.
I may stick with the stock kernel, but I feel like I will find myself installing EX on the OP5 as well.
Also, I definitely need a ROM with OMS support, Substratum ftw!
