  • Linux
  • Operating Systems

I’m reading the book Linux Device Drivers to get up to speed on writing Linux modules; I’ll be using this for an upcoming project, if all goes according to plan. This isn’t much, but if you need to get the most basic of kernel modules built, this is what you need to do.
