[Sony Cross-Device General] threader:
NB: This is a development thread!

A few days ago I embarked on merging the latest release from CAF (https://source.codeaurora.org/quic/la/kernel/msm-3.10/?h=LA.BR.1.3.7.c25 - 2021-01-28) with the SonyXperiadev unified kernel (https://github.com/sonyxperiadev/kernel/tree/aosp/LA.BR.1.3.3_rb2.14) which I've come to know quite well these last few years. I've sorted out most merging assumption errors (I think) and seem to have kept all important changes by Sony. It first started showing signs of life yesterday (I initially used 'fastboot boot boot.img' to test and didn't receive logs from /sys/fs/pstore/ in TWRP

Currently it's configured towards Aosp 7.1/8.01, the default branch I wish not to deviate too far from SonyXperiadev with CAF merged. 3.10.108 and booting Aosp 9/10/11 will come later. Right now there's a NULL pointer deference... Somewhere... Causing a fatal crash.

For anyone with motivation to help, it lives here: https://github.com/threader/kernel/tree/xperiadev/aosp/LA.BR.1.3.7.c26 -

First signes of life - log:

Fixed compiling and booting for KVM, included ranchu_defconfig for build targeting emulator - 'qemu-system-aarch64 -machine virt -cpu cortex-a57 -machine type=virt -nographic -smp 2 -kernel arch/arm64/boot/Image' - (interestingly does not happen if you remove "-smp 2")

Edit 2 :

I just built a KVM/ranchu_defconfig version of Sony's LA.BR.1.3.3_rb2.14 (almost) without changes - it outputs the same as the merged CAF-LA.BR.1.3.7_c25 with -smp 2:
