Optimizing Linux Device Drivers for Power Efficiency (LFD432)



Learn how to develop and enhance power-efficient device drivers for Linux systems.


This course is for Linux developers interested in learning how to write Linux device drivers with robust power management features. Students 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.


You 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 an understanding of Linux device drivers and experience in developing them, equivalent to have already taken LFD331, Developing Linux Device Drivers.
  • Know the basics of compiling and linking programs, constructing Makefiles, etc.; i.e. be comfortable doing application developing in a Linux or UNIX environment.
  • Experience with any major Linux distribution is helpful but not strictly required.


Optimizing Linux Device Drivers for Power Efficiency is designed to show experienced programmers how to develop/enhance power efficient device drivers for Linux systems.

Upon mastering this material, you will be familiar with the power management infrastructure and code used under Linux, and know the appropriate APIs.

The information in this course will work with any major Linux distribution.
