I am new to Linux; but I am attempting to understand the device driver architecture with the goal of learning how to write video device drivers.
I am attempting to go through the "How to Write a Linux Device Driver" book at the same time that I am looking at the device driver source code I have downloaded from xfree86.org.
I can see no similarity.
Nowhere do I find a call to register_chrdev().
Why is this?
Is there any current documentation on how to write a video device drivers?
I will greatly appreciate any help you can give.
