Course Number:  LIN2

Course Description: 

Linux is the fastest growing segment of the OS market today. This course will introduce the participant on how to design, create and implement drivers for character devices, block devices, and network interfaces. Further, participants will also learn the fundamentals of the kernel, how it works, its components, memory management, file system and more.

Objectives: 

By the end of the course the participant will be able to: Design a driver (character, block or network), Build a driver (character, block or network), Build and load modules, Debug a driver, Understand portability issues, Describe timing, Use memory management and DMA, Describe the Linux kernel, Describe how threads work on the Linux Kernel

Benefits: 

Target Audience: 

Prerequisites: 

Practical experience in C programming and at least 6-months practical experience using Linux. An understanding of Operating System architecture is also required.

Course Length:  4 or 5 days

CourseTopics:

Introduction to the Linux Kernel The Kernel Classes of devices and modules Security issues Version Numbering Data Types Use of standard C types Assigning an explicit size to data items Interface-specific types Physical layout of the Kernel source Booting the kernel Before booting The init process The kernel directory The mm directory The fs directory Networking IPC and lib functions Drivers Architecture dependencies The task structure The process table Files and inodes Dynamic memory management Queues and semaphores System time and timers Main algorithms Signals Interrupts Booting the system Timer interrupts The scheduler Implementing system calls How does system calls actually work?
