This course is for Linux developers interested in learning how to write Linux device drivers with robust power management features. Learners should be proficient in the C programming language, be familiar with the basic Linux kernel development environment and have some knowledge of kernel internals, have experience with Linux device drivers, and be comfortable developing in a Linux environment.

Learning Objectives

At the end of this course, you will:

  • Be able to understand how to develop/enhance power efficient device drivers for Linux systems.
  • Familiar with the power management used under Linux, and know the appropriate API.
  • Be Able to learn the power management framework (system-wide and device-runtime).
  • Have some forward referencing and digressions. The purpose is to get you into coding as quickly as possible. Participants will get to know about how to dynamically allocate memory in the simplest way, so they can actually write code, and later cover the subject more thoroughly. Furthermore, the order of subjects is somewhat flexible.
