Greetings!
The original code examples of Alessandro Rubini and
Jonathan Corbett's "Linux Device Drivers" were too
long with lot of ifdefs, and I found it difficult to
follow them.
Hence I decided to modify them, and also write simple
application code wherever needed. There are 14 driver
examples that have been written and tested for the 2.4
Linux kernel:
hello-ex1/
init_module and cleanup_module
current-ex2/
prints current process PID
register-chrdev-ex3/
registers character driver
param-ex4/
passing parameters to a driver
read-ex5/
reading from the driver
readminor-ex6/
reading from a specific minor number
write-ex7/
writing to a driver
writeminor-ex8/
writing to a specific minor number
kmalloc-ex9/
kmalloc usage
ioctl-ex10/
simple ioctl example
waitsleep-ex11/
sleep and awakening example
fasync-ex12/
asynchronous reader example
sbull-ex13/
simple block device driver
snull-ex14/
simple network loopback device driver
The examples don't cover all the aspects of Linux
device drivers, but, are meant for newbies who are
entering into the field of device driver programming.
You can get the above code examples from here:

I would appreciate any feedback/suggestions w.r.t the
above.
With regards,
SK
