Greetings!

Okay so here's my feedback according to my experience with this kernel in Unofficial Havoc GSI, the battery life is quite good and the performance also... I can really tell that there's small noticeable things when before and after flashing this kernel. Last, it doesn't overheat my phone easily. That's all! <3

Hi!
I'm working on a clang version of the kernel! I need a tester, i fixed almost all the errors expect oases's errors, but i believe is not important at the moment. Oases stays for Open Adaptive Security ExtensionS, should be a security patch applied to mmc.

I attached the file .img, is at your own risk i don't know if it will boot nor if something is broken.

Expected broken things are related to wifi,bluetooth, maybe gpu and sound.
Is upstreamed to 4.9.253

Give me please a feedback if someone will try!


First try failed

Cheers!

Hello,
I got a bootloop & corrupted patched recovery_ramdisk. In the next step, I got known error "func NO: 11" (recovery image), etc. in fastboot mode. Tested on stock .257.
By the way, this was my last Phenix kernel test. I love my P20 Lite :) .

Hi!
Thank you for your feedback, i'm so sorry for the inconvenient and i understand you if will not do more test. Just a question, was you fully stock? Or have you twrp, magisk? I think the problem is the oases because patch and sign mmc.... maybe is not realizable project...

Thanks you again for the effort to this comunitity @-Alf-

edit : anyway for the moment i will continue upstreaming the kernel, maybe just with gcc

Cheers!
