My scenario has no connection to this. Let me explain.

I needed a system comparable to BuildRoot and Yocto to build images and
manage complexity of two toolchains. I.e. I use it only as build system
not as an environment for doing kernel development.

I.e. what I created is

https://gitlab.com/jarkkojs/linux-tpmdd-nixos

which replaces eventually

https://codeberg.org/jarkko/linux-tpmdd-test

What I can do with my environment is essentially along the lines of

1. docker compose up --build
2. qemu-system-x86_64 -M pc -m 2G -drive if=pflash,format=raw,unit=0,file=output/firmware.fd -drive file=output/tpmdd-nixos.qcow2,if=virtio,format=qcow2 -nographic

I use this in Fedora Linux where I do all my kernel development. This
is something I plan to update to MAINTAINERS as a test environment.
