[Linux-ia64] Driver development document

[Gururaj Ananthateerta]

I am newbie to Linux.
Is there any document which explains howto write linux network drivers for
ia-64.?

Thanks

Gururaj-

The same document that explains how to write IA32 drivers :-)

Seriously, all of the kernel interfaces you should need should
be the same between IA32 and IA64.  It's amazing how many IA64
drivers were created by just re-compiling the IA32 versiion with
no source code changes.

I would recommend starting with the book `Linux Device Drivers'
by Rubini.  It's kind of out of date (written for the 2.0 kernel)
but it gives you a good idea about the basics.

FWIW - It may be good, for someone in the real know, to document how
to modify or write a driver source so it would detect whether it was
running on ia32 or ia64 or even other type system and thereby be able
to take advantage of larger memory models.

From what I understand, many of the current drivers go through
copydown when used in the ia64 architecture and could be improved
upon.

My $0.02 worth of thoughts on this discussion.

There is a refreshed version (for 2.4 kernel) published this year.

There really isn't any need to do so, if you follow the documented
APIs this will work automatically.
