Modules & the Kernel Build

Not started yet — the monolithic-plus-modules model, writing and building a hello-world module, and the kernel-module Makefile shape from memory. 9 bytes.

What this topic will cover

  • The monolithic-with-modules model vs. a microkernel, and a tour of the source tree (arch/, drivers/, kernel/, mm/, include/).
  • A hello-world module — module_init/module_exit, the __init/__exit markers.
  • The module Makefile — obj-m and make -C .../build M=$(PWD), written from memory.
  • Module tooling — insmod vs. modprobe (and dependency resolution), rmmod, lsmod, modinfo.
  • MODULE_LICENSE and kernel taint, module parameters, and printk log levels as the only debugger available at first.
  • Building a kernel end to end — menuconfig, make, and what vmlinux/zImage/the modules directory each actually are.

Not yet catalogued — check back once this topic is underway.
