Hi Willis,
To get EOF in the application program, you just need to return 0 at your
driver's read function. IMHO, I think that you can use IOCTL to do your
driver easily.

Hi Willis,

Like this:
multi.h
#ifndef MULTI_H
#define MULTI_H
#include linux/ioctl.h
Hi Willis,
How is your FPGA peripheral accessed ? Is it memory-mapped or you need
special IO command ?
If it is memory mapped, maybe you can ask the kernel to map the
registers into your process (using mmap), so you don't have to design
your own device driver.
Btw, I'm currently driver

First, some background. I am working on device drivers for a FPGA that is
