How do I write a Linux driver?

To build a driver, these are the steps to follow:

1. Program the driver source files, giving special attention to the kernel interface.
2. Integrate the driver into the kernel, including in the kernel source calls to the driver functions.
3. Configure and compile the new kernel.
4. Test the driver, writing a user program.

What are the two types of drivers in Linux?

There are various types of drivers present in GNU/Linux such as Character, Block, Network and USB drivers. In this column, we will explore only character drivers. Character drivers are the most common drivers. They provide unbuffered, direct access to hardware devices.

Where does Linux store drivers?

/lib/modules/ directory
Many Drivers come as part of the distribution’s Kernel. Use Them. These Drivers are stored, as we saw, in the /lib/modules/ directory. Sometimes, the Module file name will imply about the type of Hardware it supports.

Why can’t we use C++ for device driver development in Linux?

That’s why we can use only these two languages for Linux device driver development. We cannot use C++, which is used for the Microsoft Windows kernel, because some parts of the Linux kernel source code (e.g. header files) may include keywords from C++ (for example, delete or new ), while in Assembler we may encounter lexemes such as ‘ : : ’.

What is this course on Linux device driver?

This is course is designed for the freshers or professional who wants to learn or enhance their skills on Linux device drivers. This course contains prerecorded Linux Device Driver video classes or Linux Device Driver video tutorials on linux device drivers concepts , which covers from basic to advance concepts . Below is the course outlines

How do I write a device driver for Linux?

For this reason, writing a device driver for Linux requires performing a combined compilation with the kernel. Another way around is to implement your driver as a kernel module, in which case you won’t need to recompile the kernel to add another driver. We’ll be concerned with this second option: kernel modules.

What is a Linux kernel driver tutorial?

Nevertheless, one of the purposes of this short Linux kernel driver tutorial is to show how to work with logging into the kernel and how to interact with device files. These tools may be simple, but they come in handy for any driver, and to some extent, they make the kernel-mode development process richer.
