Character device driver programming linux
Character device drivers, If for character devices system calls go directly to device drivers, in case of block an analogy from object-oriented programming: if we consider a class inode, You can cat its device file (or open the file with a program) and the driver will put the number of times the device file has been read from into the file. We don't support writing to the file (like echo 'hi' > /dev/hello ), but catch these attempts and tell the user that the operation isn't supported.
Character Device Drivers, Be aware that a file is a kernel level structure and never appears in a user space program. It's not the same thing as a FILE, which is defined by glibc and would The file_operationsstructure is defined in linux/fs.h, and holds pointers to functions defined by the driver that perform various operations on the device. Each field of the structure corresponds to the address of some function defined by the driver to handle a requested operation.

What is the difference between kernel drivers and kernel modules , If you build your kernel statically and disable Linux's dynamic module loading feature, you prevent run-time modification of the kernel code. This provides A Linux kernel driver is a specific type of program that allows hardware and software to work together to accomplish a task. Though Linux is often known as an operating system, a Linux kernel is a component of the Linux system. This Linux kernel operates to manage the system’s processes as efficiently as possible.

Device driver development
Start here to learn fundamental concepts about drivers. You should already be familiar with the C programming language, and you should understand the ideas of function pointers, callback functions, and event handlers. If you are going to write a driver based on User-Mode Driver Framework 1.x, you should be familiar with C++ and COM.
To the IoCreateDevice, we pass in the driver object, a pointer to the Unicode string we want to call the driver, and we pass in a type of driver “UNKNOWN” as it’s not associated with any particular type of device, and we also pass in a pointer to receive the newly created device object.
A key concept in device driver development is something called interrupt handlers – C or assembler functions that are started automatically by the hardware (at any point in time, completely asynchronously from the application software execution) whenever a hardware event is signaled. It works like this:
