Any more details on the governors, hotplugs etc?

good, i think the days of over customized kernel are over. What we really need now is a close to stock, with a few but important feature like kcal.

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.
Regards

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

Hey, could anybody pls post the stock oxygen 2.0.2 boot.img as I dont have the pc with me right now. I need to get the player working till the dev gets this fixed.
Appreciate!

Ready to help you but where can i find that boot.img file??

Anybody willing to test out a new ROM for me? You need to test it right away and report to me ASAP.The user must have a knowledge to trigger a logcat.I asked yesterday about the testers in the CM12.1 thread but I failed to get a suitable reply from any of the OnePlus Two users.PM me for the download links.

I have been waiting for this!!!! Thank you.

No sim detect
Sent from my XT1562 using XDA-Developers mobile app

@mw1man no problems here with dualsim. i converted my single sim to dual today and flashed phoenix kernel over stock.
Also the kernel runs pretty smooth so far. I changed the cpu governor to impulse and lowered the minimum cpu freq of the big cluster to 400 MHz. Will report back!

Apparently hotplugging only works with Interactive Governor. Will continue testing with default settings.

Flash over any kernel, no need to flash stock.

This is great. Was waiting for another msm hotplug kernel. Just flashed on stock and running fine. Lets hope it doesnt reboot when reaching around 30% like ultra kernel did. Up and running. Thanks a lot.

INSTALLATION INSTRUCTIONS​
I Would highly recommend clearing data of your current kernel adiutor/any other apps that you use to control features or better yet since this is a "FLASH AND FORGET" kernel uninstall them you don't need it now.
Download the .zip file from the downloads section.
Reboot into recovery.
Select the zip file and flash.
this kernel is "FLASH AND FORGET" meaning everything is set and optimized by default if you mess up by changing default settings i won't provide any help

Kernel Settings?
i prefer to use stock settings but if you want more battery then change the governor to lionfish but it might lag so i will just ignore those whinny comments about lagging.
Warning -> if you flash this kernel on stock rom! wifi will stop working.
Having problems? or anything you wanna ask? Mention me on your comment.
How to use the features that are implemented in the kernel?
Download kernel adiutor from playstore and give it root permissions.
Explore!.
Saw a feature in some other kernel and you want the same feature too? then request for it in Feature Requests section I'll try my best to bring it for you.

How To Build Your Own Kernel?
*Each Step Is Very Important Be Sure To Follow Each Steps And Do As I Said.
*You Are Gonna A 64bit Linux OS Any Will Do I Use Ubuntu 16.04 LTS.
*Let's Setup Your Build Environment.
*Open Terminal(ctrl+alt+T).
*Now Type "sudo apt-get update" Then Hit Enter And Let It Complete.
*Refer To This Awesome Guide By @akhilnarang To Automatically Install All The Proprietary Things.
*Where "<name-of-script>" Type "ubuntu1604linuxmint18.sh" If You Have Ubuntu 16.04 Then Hit Enter And Let It Complete.
*You'll Need Kernel Sources Again Open Terminal And Type "git clone https://github.com/ShadowReaper1/android_kernel_asus_Z010D.git" And Let It Complete It'll Take A While Depends On Your Internet Speed.
*Now To Compile The Kernel Download A arm64/aarch64 Toolchain You Can Use Any Gcc 4.9 Toolchain I Prefer Google or UBER Toolchain.
*Open Kernel Directory It Should Be Named Like "android_kernel_asus_Z010D" And Open build.sh And Edit The Parts Where "change" Is Written According To Your Toolchain Path And Cpu Cores After Editing Save It.
*It's Time To Compile The Kernel Open Terminal Inside Kernel Directory And Type "bash build.sh" or "./build.sh" Then Choose The Appropriate Options And Sit Back And Wait For It To Complete And You'll Find Your Kernel.zip inside "base_files" Folder.
*What To Do Next? Flash It .
*Add Features As You Like And Fix Bugs.
*Don't Come To Me Crying How To Add This And That I Won't Help In That Matter See Other Kernel's Of Other Devices With Same Specifications Use That As Reference And Cherry Picks Features From Them Resolve The Conflicts For More Information Refer To This Excellent Guide By @eagleeyetom.
*One More Thing Leave A Like And Press That Thanks Button .

550kl and 500kl are different i guess?

I will upload a custom kernel for z00l, in time. Be patient.
The last time I compiled a kernel for linux (pc desktop) was like... 10 years ago, lol. Need some time to get used to the protocol now.
here's a guide, everyone should try their hand at compiling a custom kernel, but make a full phone backup, just in case.

- usb fast charging
- i/o scheduler: fiops, sio, tripndroid etc

NOTES:
*This kernel has been designed with stability and performance enough to get you a
good battery life.It has been specifically designed for normal app usage and multitasking.
*This kernel is not for heavy gaming.Please be aware while playing games/using heavy apps.
*RAM usage,battery life,performance etc. can vary with usage.Please dont complain about any problem if you apps
are wildly running in the background or you dont maintain your device properly.Sometimes it is not the fault of the kernel.
.Please provide proper bugreports(/proc/last_kmsg,dmesg output,/sys/fs/pstore/console-ramoops files can be provided)
otherwise your bugfix request will be ignored.

I will try...

thanks...:good:

it works
I will test the performance for the next few days...
1.if the screen turns off there is an incoming message, the device does not wake up.
(WhatsApp apk)

this is unbelievable a custom kernel for our device many thanks and huge respect God bless you brother. i have 1 request too please try to build Linux 4.9 kernel for this device too in future if you can (maybe it's too much to ask but it's only a request)

ram management is good due to inclusion of swap partition (1gb) and battery seems to be draining fast

Hi, i never used a Kernel before. I used lots of roms but I dont know what is kernel and why is it important. Anyways.
I was wanting to use KCAL app, it seems it's working with it. I have some questions.
1- how to back up my own kernel, so if I want to restore it I can go back to my original kernel.
2- is it just some kind of backend thing, if I install this it will not act like a rom and reset all the data on my phone right?
3- somebody says it have battery drain problem above in the comments. I don't care about battery drain so much but how it drains, like 1% per 2 or 3 minutes is okay but if it's less than this it won't be okay for me.
4- as I said above, I will use it for KCAL app, is there similar great things that I can do with custom kernel? I don't know much about it.
That's all. Sorry for my bad English.
Thanks

1. first backup your boot partition via twrp.
restore if you want to return to your original kernel
2.yups...

thanks bro

All the cpu cores are running at max frequency all the time in this kernel that's why it's draining battery so fast

Does i can flash it on havoc os 10

the battery drain is normal here, actualy is better than the default in custom rom ProjectEva

ProjectEva is the default kernel pre-installed in custom roms for our device. This kernel is better for gaming, but Revvz kernel is better for multtasking, and is for that reason that i use Revvz kernel.

It has not worked for me in HAVOC OS 10, however in roms with Android 9, Evolution type, etc, yes

I installed it after the rom and it gave me brick
I had to reinstall the rom and not install that kernel
I'll try again, thanks
