Booting a Rust-Enabled Kernel and Loading the Minimal Module
Before writing anything of your own, you prove the whole chain works: a kernel built with Rust support, started inside an emulator, into which you load the smallest possible Rust module and watch it announce itself in the log. This is the one hello-world moment of the path, and its purpose is not the greeting but the proof, because a toolchain that is half-configured fails later with errors that look like bugs in your driver. After this you have a build-and-boot loop you can repeat in seconds, which is the workbench everything else is built on.
Questions this Concept answers
- Why does this Concept spend a whole stage loading a module that only prints one line to the kernel log?
This Concept is waiting for its first lesson!
