Audience

This course is designed for anyone interested in learning how to write device drivers for Linux. Learners should be proficient in the C programming language and be familiar with basic Linux utilities and text editors.

Learning Objectives

At the end of this course, you will be:

  • Familiar with the different kinds of device drivers used under Linux, and know the appropriate APIs through which devices (both hard and soft) interface with the kernel.
  • Able to know how to develop device drivers for Linux systems, and give them a basic understanding and familiarity with the Linux kernel.
  • Able to Learn Device Drivers and Linux Kernel. Since device drivers are an integral part of the kernel. most device drivers use only a subset of kernel functions and one need not learn everything about the kernel to do a device driver. Yet while device drivers do not control important kernel features such as scheduling or memory management, the more you know about how Linux handles such things the better a device driver you can write.
  • Able to learn kernel internals and algorithms and examine the functions which are normally used in device drivers. More details on things such as scheduling, memory management, etc., belong more properly in a higher level treatment (or lower level depending on how you define things).
  • Able to have some forward referencing and digressions. The purpose is to get you into coding as quickly as possible. For example, we will tell you early on how to dynamically allocate memory in the simplest way, so you can actually write code, and then later cover the subject more thoroughly. Furthermore, the order of subjects is flexible, so feel free to vary it according to your interests.
