A device driver (often referred to as driver) is a piece of software that controls a particular type of device which is connected to the computer system. It provides a software interface to the hardware device, and enables access to the operating system and other applications. There are various types of drivers present in GNU/Linux such as Character, Block, Network and USB drivers.This function registers a major number for character devices. Arguments of this function are self-explanatory. The major argument implies the major number of interest, name is the name of the driver and appears in the /proc/devices area and, finally, fops is the pointer to the file_operations structure.
Linux is a 32-bit multitasking and multimedia operating system that enables applications to access the devices on a system to perform specific functions. It supports a wide range of software from TEX to the C/C++ compiler and TCP/IP. The Linux system provides a complete Unix programming environment which includes standard libraries, programming tools, compilers and debuggers. You can understand the terms like cross platform, target hardware and know how to rebuild Linux to target hardware. We offer training course for students as well as professionals who want to learn about Linux, porting of Linux on ARM9, device driver development, system programming and ARM9 and kernel configuration.
