Course Overview:
This hands-on course focuses on Linux internals and Linux kernel programming. Participants will learn about the Linux kernel architecture, programming in the kernel environment, space considerations and debugging mechanisms. Following this course, participants will be able to develop Linux kernel modules.
Examples are in C.
Who should attend?
The course is suitable for software architects, designers, developers and analysts with Linux experience who need to learn and program in the kernel environment.
Prerequisities:
- Linux experience is a must, including user mode programming (using gcc, Make) and editing
- Programming experience in ANSI C, with the standard library, including sockets programming is also a requirement
