About
Learn how to develop and enhance power-efficient device drivers for Linux systems.
Audience
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.
Course Materials
Authorized printed training materials from The Linux Foundation. As part of your registration, a printed copy of the course manual will be course manual will be provided. If you are attending in person the material will be available onsite on the day the class begins.
Course Description
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.
Prerequisites
- 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.

Why train with The Linux Foundation
The Linux Foundation is the go-to source for training on virtually every aspect of Linux and many other open source technologies. Here are a few things that make The Linux Foundation the right choice for training:
- The Linux Foundation is the non-profit organization that hosts Linux and many other open source projects, employs Linux creator Linus Torvalds and hosts kernel.org (where all Linux kernel updates are released).
- Being so close to the kernel The Linux Foundation is constantly updating training to ensure that the most up-to-date information is being thought. Linux Foundation Training is unique in that all our training courses are designed to work on all major Linux distributions (including RedHat, Ubuntu and SUSE).
- The Linux Foundation does not sell any software or support services so there’s no hidden sales agenda in the training material. The only goal is to help students learn the material.
- When you train with The Linux Foundation, you’re learning from instructors who are comfortable across all major Linux distributions and can answer student questions regardless of the distribution you’re using for the class. You are truly learning from the experts.
