Master the basics of configuring and troubleshooting the Linux kernel. Learn how to read and write proc files, work with loadable kernel modules and source code, and more.
- The Linux kernel is generally considered to be the biggest and most important open source project in the world. The kernel lies at the heart of all distributions of Linux, from super computers to Android phones. It powers millions of web servers and is enabling the Internet of things. I'm Kevin Dankwardt, and for nearly 20 years, I've guided teams in building devices that use the Linux kernel. In this course, I'll show you the basics of what the kernel is and look at how the kernel boots up.
After that, we'll take a look at using and configuring Linux kernel modules. Then we'll write out own module. Finally, I'll show you how to download the source of the Linux kernel and configure and build it for yourself. Working with the kernel of an operating system may sound daunting, but it's easy to get started.
We survey the Linux kernel specification, boot process, and loadable kernel modules. You will practice techniques such as downloading and searching Linux kernel source code and configuring a Linux kernel from scratch. Challenge and solution videos at the end of almost every chapter allow you to test your new Linux skills along the way.
