[KERNEL] [11.0.0] Kazuki Kernel [February 18, 2022]

[Kaz205]

Introduction
Kazuki Kernel is a kernel based on Sultan's kernel with some additional modifications aiming to give a better experience than the stock kernel.

Compatibility
This kernel only supports devices running the latest firmware (vendor.img), and will NOT BOOT on anything else.

Features

• Everything from Sultan Kernel
• Backports from Sultan's Pixel 4/XL kernel
• Patches from kdrag0n's Pixel 2/XL kernel
• New set of optimized CPU frequencies and EAS energy model
• Wi-Fi WPA3 support
• Miscellaneous treewide optimizations

Downloads
Latest kernel
Enable support for flip covers (optional)

Credits

• Sultan Alsawaf (Sultanxda/kerneltoast) for his kernel and help
• Danny Lin (kdrag0n) for his patches and freqbench
• Everyone else who I cherry-picked from

Flashing straightaway!
Thanks for your work
Working fast and snappy on taimen running ProtonAOSP 11.4.0

Is anyone successful in flashing on crdroid? What's the experience like

 

[ValKyre]

Flash in walleye run 11.4 proton OS . Boot fail. Auto boot to bootloader
Show notify yellow at the bottom: ERROR: BootLinux Failed: Not Found

 

[Prattham]

Can i use this on Android 10?

Did you flash the kernel correctly? It appears that your boot image is corrupted.

Can i use this on Android 10?

No, only Android 11 phones with the latest firmware are supported.

Download your kernel.
And flash via twrp

 

[Kaz205]

It appears that I had removed important dtb files which made the kernel unbootable on walleye. I uploaded a new build to (hopefully) fix the issue. The new build should be called "Sultan-kernel-plus_20210418-fixup.zip".

EDIT: It's fixed and is safe to flash.

Yay... It boot now. But do u know why it same issue like other kernel ? (kirisakura, sultan old version,...) .
The issue is: when restart, the boot amination very very slow. Some time when the screen of press power key to turn on phone it take 3-5s to open (sometimes not usually) .

 

[Kaz205]

New build is up with some original commits. Nice!

新建了一些原始提交。好的！

希望优化的更好,感谢

any settings for rgb to eliminate the yellowish from white?

 

[Kaz205]

Newwwww build

 

[neekless]

@Kaz205 I've been following your github repo for a while and there was a period of time where you used PELT and is no longer using it. Just wanted to know what are your findings regarding PELT?

Yes it's present.

I initially switched to PELT in hopes of lower jank. However I switched back because it turns out that PELT breaks live frequency stats and that jank is more or less the same as WALT with some proper tuning.

 

[Kaz205]

New build is out with lots of cool changes!

 

[Sui77]

May I use this kernel for 10?

 

[palimatix]

May I use this kernel for 10?

No. Already answered by dev before in this thread... Post#6

hehe less jank

flashed for some testing....
