* Aspiring engineers with 0 to 1 years of relevant experience interested in kernel development or low-level programming.
* Computer science students seeking practical experience in device driver development.
* Junior software developers looking to specialize in Linux kernel programming.

* 20 sessions of 1 hour each.

* The course will conclude with a hands-on project that involves developing a character device driver using C, Linux Internals, Linux command-line tools, and Bash scripting.

Participants will:

* Understand the architecture of the Linux kernel and its module programming.
* Learn the fundamentals of device driver development, focusing on character devices.
* Gain practical experience with kernel module programming, including device registration, file operations, and communication between user space and kernel space.
* Master debugging and testing techniques specific to Linux kernel modules and device drivers.
* Complete a project that demonstrates their ability to develop a fully functional Linux character device driver.

* Basic knowledge of C programming.
* Familiarity with Linux/UNIX command-line interfaces.
* Understanding of fundamental programming concepts and data structures.

* The candidate should hava already finished following training modules...

* Module.000: Linux System Administration...
* Project.001.C Programming and Data Structures on Linux...
* Module.011: Shell Scripting using Bash...
* Project.003: Linux System Programming...

Introduction to Linux Kernel Development

Overview of the Linux kernel, kernel space vs. user space, and the role of device drivers.

Setting Up the Development Environment

Configuring a Linux development environment, including necessary tools and kernel sources.

Basics of Kernel Modules

Writing, compiling, inserting, and removing kernel modules.

Introduction to Device Drivers

Role of device drivers, types of device drivers, and the structure of a character device driver.
