Modular Kernel

Painting a Picture

Imagine we have a kernel, and have a my_mod.c file that defines some module that the kernel can use. This is not meant to be a standalone program, so it doesn’t have a main entrypoint, but instead something like mod_init().

We compile it to a .o file. We want this file to be able to integrate into the kernel without necessarily linking into it.

This requires some semblance of a dynamic linker/loader.
