[KERNEL] Sphinx Kernel [10/11] [4.9.261] [Clang 11] [13.03.2021] v3.6

milouk · Mar 13, 2021

Introduction
Ahoy everyone,

I decided to share my personal custom kernel with all of you. The main reason i started developing this kernel is to balance performance / battery / security and also add features.

I believe i have included most of the usually requested features. If your feature is not included you can ask for it and i will try to include it as long as you don't ask for ETA's. I am a student and i do this on my spare time.

Pie kernel is based on LineageOS 16.0 sources for dipper and is compiled
with SdClang which is Qualcomm's LLVM Compiler for extra performance. [EOL] - Final Version is 3.1

10 kernel is based on LineageOS 17.1 source for dipper and is compiled
with latest sources from LLVM for Clang 11.

So let's jump to the interesting part!

Notes

I bear absolutely no responsibility. If you brick your device. If you are not sure what a kernel is, how to flash it or how to restore your phone in case something goes wrong then do NOT proceed.
Moreover, you should flash this kernel only over the stock kernel that came with your Rom.

Hello Guys,

I am the developer of Sphinx Kernel for Bullhead.
I bought a Mi 8 but it still hasn't arrived , i am expecting it this week or next week.

However, i have managed to compile a Test kernel for Mi 8 (Dipper) from stock sources.
It is very possible that it won't boot. I would like someone to test whether it boots or not. Currently it contains no customizations but once i know it boots i will start adding features.

P.S You take the risk, if you brick your device i bear no responsibility.

mmm Interesting, im wondering whether the "bug" is in the source itself or in the Anykernel2 config. If i had to guess i would say both of them are correct hahaha. i might change a thing or two and if it doesnt work im going to wait for my mi 8 to arrive. Also which rom did you flash it on?

I used the dipper_user_defconfig, the one which is also supposed to use (is written in commit at github from xiaomi staff)

So here is the log i got from recovery.
The only thing i could see that the boot partition is busy
"No such file or directory
mount: mounting /dev/block/sde48 on /system failed: Device or resource busy"
And one thing.... Maybe the Kernel is for MIUI 9 8.0 (don't know if it exists i am on MIUI 10 Global stable xiaomi.eu)

EDIT:
Excuse me here is the real dmesg

Something in the kmsg...

Failed to setup verity for '/vendor'

This was something which also happened when i used my kernel with magisk, something in vendor did make problems

EDIT:

ok so from the log you sent me i see this

Code:

[    6.517314] init: [libfs_mgr]Failed to get verity metadata '/dev/block/platform/soc/1d84000.ufshc/by-name/vendor': File exists
[    6.517378] init: Failed to setup verity for '/vendor': File exists
[    6.517415] init: Failed to mount required partitions early ...
[    6.517421] init: panic: rebooting to bootloader
[    6.517433] init: Reboot start, reason: reboot, rebootTarget: bootloader
[    6.517446] init: android::WriteStringToFile open failed: No such file or directory
[    6.517460] init: Shutdown timeout: 6000 ms

could you please locate the fstab file of Mi 8 and send it to me? i want to see the boot block name. Also if i had to guess about the kernel not booting id say it has to do with the kernel requiring encryption (?) im not sure ill dig into it
