    Question need help in writing a device driver


    Hi!

    I am new to writing device drivers, and I would need to write one like this:

    Write a driver similar to the one with a circular buffer, this time blocking on a full buffer. Additio- nally the driver shall notify a program after an empty buffer received some bytes, so the program knows, there is something to read.

    Can anybody help me?

    Thx: Gogo

    Welcome to the forums!

    This looks like a homework question... is it?

    What have you written so far?

    You can check this online book for some tips and advice about your device driver questions.

    Have fun with Linux...

    Well, I haven't gone far yet. I don't really understand the difference between the circular fubber and full buffer.
