[KERNEL][AOSP/LOS] SINAI-N4 Kernel

[sudokamikaze]

There's a bad news

I decided to stop development. Sorry about that
I have no time & desire for that...
I've got a job and so on

Instruction: How-to swith back to ROM's kernel:
1. Download fresh build of your rom
2. Go to recovery and perform dirtyflash
3. Wipe cache
4. Reboot to OS

I had to re-open thread and I'll keep it opened until @moriel5 send his changes
I also release last testing changes which worked well

 

[moriel5]

Alright, I have finished with my -50mV undervolt.
No stability issues whatsover, and a consistent drop of 1-2° (I'm guessing about 1.5°) celsius under load.

Now for the last leg of the journey, -75mV.

Unlegacy team pushed their new build which contains my binder changes

So, I've pushed new build(link in OP post) which creates compatibility

Enjoy

@sudokamikaze can you please update binders in aosp build also

Enabling 64-binder requires to update device-tree. Not all maintainers want this and I'm not team member of LIneageOS/ETC
Also if you enable 64-bit binder mode in kernel and device-tree(e.g ROM) doesn't support that - you'll get bootloop

I'm only member of Unlegacy-Android & PixelDust

I've updated build as I said before I stopped development. I'll continue my work in the middle of summer or maybe in the end

Can I flash this kernel to Los 15.1 official build? If not when will it be available

You can't. And there's no plans about that.

Hi there guys! I'm back!

Changelog:
sdcardfs updates from latest kernel_common/3.10 branch (which are already in Unlegacy's & LineageOS' kernel)
Rebased sources, I've made cleanup of unneeded & buggy changes. Now UI works smoother
Optimizations from UA's hammerhead's kernel
F2FS Updates (Probably I've already released a build with it but I don't remember exactly so I decided to mention that again)
Removed spectrum support because I don't really use it and i'm not sure that someone still using it
Ramdisk cleanup. Now kernel flasher hooks into rom better(Especially for Unlegacy-Android rom). It means that kernel settings which I've set in ramdisk will finally work.

I hope that battery drain have disappeared because my battery isn't in perfect condition

And kernel will have Android Pie support as soon as it gets ported to mako

Links are updated! Check them out!

Cheers I am in a mood to throw a great party for you. Kudos to your dedication and thanks a lot.
Will report back soon after installing.

Warning for Unlegacy-Android users

I've made a mistake in ramdisk configuration so you will see MPDecision & Thermald in your KernelAdiutor
And you must disable them - or you will encounter wakeup/performance/batterydrain problems. I'm working on it and I will release new build shortly

 

[sudokamikaze]

Build which fixes those mistakes which I mentioned before is pushed!

 

[bgoel4132]

the latest build along with gcam tool fix and google cam version 3.2 fixed video recording for me in faie nexus rom
which was the only problem in the rom
others please confirm the same

Cool! Did you encounter battery drain?

no i didn't encounter a battery drain.
everything just works fine but yesterday my phone rebooted of no cause and the camera stopped functioning completely on all apps which got fixed after a reboot
dont why this happened the same had happened earlier too but the camera was functioning properly then.

Does this still cause the powerhal spam in catlog relating to touch boost when mpdecision is off? aswell as the mpdecision being unable to change cores and such? Or is that something in the rom that needs to be told to ignore?

Also checking the OP, It says to use the kernel auiditor mod, but that's really old, Will KA-mod reborn also work?

Hello, I'm trying to install this kernel, but everytime I do, when I reboot, I get stuck on the Google screen right before the system boots. I have tried installing this multiple times on top of NitrogenOS and CarbonROM (ROM, then GApps, then Kernel), each time making sure to wipe everything (and no errors occured) except internal storage, but the same thing happens everytime (I get suck on the Google screen when I reboot). I have TWRP 3.1.2-0 installed and all the partitions are formatted as ext4 (though when I press on "format data" I get an error "unable to wipe '/data' -- unknown file system 'auto'. Unable to format to remove encryption.", I don't know if this is related?). I do not get any error during the installation. Any help would be very appreciated!

If you try to flash this kernel on anything lineageOS based remember that the version for lineageOS based ROMs is only supported to android 7 nougat, an Oreo based kernel is only available for AOSP based ROMs.

If you followed this information outlined in the OP already and still have issues proving logs would be a great idea, TWRP has a logging feature where you can grab logs after a failed flash...

Edit: @sudokamikaze nice to see you back man! :highfive:

Well as far as I know, NitrogenOS should be AOSP based and therefore it should work with the AOSP version of the SINAI kernel? Here are the logs as you suggested (fyi I installed NitrogenOS (2018-08-07), then OpenGApps Aroma (2018-08-21) and then SINAI N4 AOSP (2018-08-16)).
