One of the most commonly used Operating Systems in IT departments of most organisations is Linux. For professionals to work in these departments, it is important not just to know the OS but also its device drivers. Skills on process management, memory management, scheduling, time management and interrupt handling are taught to professionals who enrol for a Linux device drivers course.
Several types of system calls are made in Linux. Candidates need to understand the significance and the various types of system calls. Virtual File System, time management and interrupt handlers are also given substantial attention by the experienced instructors in reputed training institutes. As mentioned above, process management is also considered vital in Linux. It can be understood through multitasking, scheduling algorithms and Linux process scheduler policy.
Target audience for Linux device driver training
Working professionals in the embedded systems field and professionals who wish to develop their programming skills are ideal for this course. Even final year students from MCA/BCA and those in 3rd and 4th year of B Tech. can sit for this training to get a broad perspective of Linux. However, it is essential that candidates enrolling for this training must have a prior knowledge of Linux and shell scripts.
Important objectives of training in Linux device drivers
While you may have read about system calls, scheduling, process management and other features above, there is also much to be learnt about the device drivers themselves. The concept of the device driver is introduced to participants, along with which they also get to know about the different types. The functions for loading or unloading a module are also taught to the candidates. They understand more about the loadable modules and their benefits.
In addition to the above, one must know how to write a device driver program. Different device information is required and candidates get hands on practice on writing the program. Compiling and loading modules, userspace interaction, registering character device drivers and Lcd implementation are some of the other objectives of the Linux device drivers course. Linux can also be known through one of the embedded systems courses.
