What you'll learn

Write modules to insert in kernel to alter the behavior and functionality of Linux kernel.
Student should be able to compile linux kernel from official git source or download the standalone kernel for compilation
The course introduces the concept of device driver and Major and minor number to effectively write a linux driver as a module or in kernel
In depth explanation of jiffies and utilization of jiffies for getting either timer tick or clock for further work in those areas
Understanding of device file, node, major number, minor number and numerous calls with respect to rebuffs
Understanding of kernel file system and data structure like proc, debuts etc for easy kernel debugging

Description

This course guides a student for the basic understanding of Linux Kernels

Familiarize students with kernel compilations and different ways to achieve the same.

Introduce the character device Driver and explained in details like copy_to_user and copy_from_user

Explained the concept of Jiffies and a practical example of working Jiffies code

Explained in depth about debugfs and its various calls.

Explained in details with the help of power point as to how system call works.

The course provides the various way a system call can be invoked using software interrupt or directly invoking the syscall layer.

At the end of this course students would be well versed in kernel compilation and writing modules on Linux kernel.

This lecture series also guides students as to how to effectively get involved with Linux open source community and write patches which would be accepted upstream.

The course intends to build a niche in students who are devoted in kernel programming but couldn't gather enough resource at single location to build a career out of it.
The intention is to give a build blocks to students to understand the kernel, driver, file system, compilation, module insertion, deletion, device file, communication between user level and kernel level and how to code from kernel perspective rather than general c code.

In depth details of the explanation of concepts to communicate with kernel using either copy_from_user, copy_to_user or using the debugfs or proc fs.

Explained in details how to use virtual machine like VMware fusion of VMware workstation to setup a system for Linux kernel compilation and programming as virtual machines we can take snapshots and if there is problem we can simply revert to older snapshots for quick development, without corrupting the entire Operating system.

Who this course is for:

Students and professional who is willing to make a career in Linux internals and operating system.
Linux enthusiastic who would like to see what is going on in kernel level either due to hobby or curiosity and wanted to build a career out of it
Students who wanted to understand the kernel of other operating system but couldn't do so because of closed source, can learn linux and apply the almost similar concept in other OS
