I need to port a Tru64 Character device driver to Linux.
I have begun to read "Linux Device Drivers" and looking at
the source for the Tru64 device driver that needs to be ported.

From looking at the code it is not readly apparent what the hooks into
Tru64 kernel are. I can't even tell if True64 has the same
architecture as the Linux kernel.

What I am looking for is some guidance on the True64 device driver
interface
so I can make a comparison with the Linux interface. Hopefully they
are
simular enough where the port will be fairly straight forward. Yea I
like to dream.

Does anyone have any ideas or practical experience that can help me
out?

You might try hunting down Jym Paradis, who did the Linux kernel port to the
Alpha. He's working in Boston these days, I've seen him here.

You don't say what version of Tru64 the driver you have is written for,
but there are guides to writing device drivers for most versions of tru64
after 4.0 on the web.
Try http://www.tru64unix.compaq.com/docs/pub_page/devdoc_list.html
for a start...
This should give you some insight into what the original author of your
device driver was doing and allow you to start to port the driver.
Hope this helps
