FAQs :

Q. How to install the kernel?
A. Flash on stock kernel using TWRP, do not dirty flash on any other custom kernel!

Q. How to roll back to stock kernel?
A. Backup your kernel before flashing this, if you feel like going back to stock, just restore it via TWRP.

Q. I'm having bootloop, what should I do?
A. You will face some bootloops on first installation, it'll boot in some time.

TBH, audio-kernel shouldn't be outside techpack.

First thing: that's not how you commit a Linux kernel. You completely destroyed all the commit history, so now no one can see the changes you applied. Second thing: I suppose you didn't even test the kernel you compiled since I don't think you even have the device yourself (the K20). You just have the K20 Pro and for some reason wanted to compile a K20 kernel too after compiling one for the K20 Pro. Third thing: those changes are so minimal and negligible that it wouldn't really make much sense to replace a stock kernel with this. No real reason for users to flash this kernel, but users can do what they want. Post a performance comparison between stock and this and then, only after that, people should really consider if it's really worth it.

Flashed on paranoid. Only issue I have that my screen turn off after a few seconds when unlocking it. This happens only when not used the phone for some minutes.

Edit: unusable for me. Screen turns black all the time

I had mentioned in the initial commit that it was with the v1 baseline not the stock one(If you want to see the full commit history check the raphael repo), secondly this is a test release meaning I want inputs from users!
If you don't like it, don't use it let other users decide what they want.

what the point of testing it if it's very close to stock? did you mean testing it's stability?

Mi sources cause issues even if compiled without any changes! Need to fix those first before adding new features.

[mahmutuslu]

mi room 9.8.15 bootlop

 

[alsartawi]

infinite bootloop on xiaomi.eu 10.3.14.0, also tested on 9.8.15 same bootloop, did you tested your self? if yes on what rom?
edit: i am not complaining from the result of bootlooping, i am just telling the feedback of my tests, we really need a custom kernel of this device, so plz continue your work and ask me when ever you want me to test it, thank you.

AOSP/LOS Test Versions

As I mentioned before, Xiaomi code is a pain to work with!
There is no point in adding more features if you don't have working wifi or other major bug! We need a stable base first.
Interested users can test out new versions on LOS roms, please give it time for first boot!
Flash it via TWRP or fastboot.

On LOS 16 everything works except fingerprint scanner, can't register new one and doesn't work with previous
After flashing test1 -> fastboot
Booted only after flashing test2.
Should I try on fresh installation for fingerprint ?
