Hi,

 I am trying to write a PCI ethernet driver for FreeBSD 3.4 release.

I have some  questions

 1. How can I convert physical address to virtual address . What I want
is to read the physical address from the device register  and to copy it
to host memory. From my earlier post  I found that I can use vtopys
macro to convert virtual to physical address. Now I want to do the
reverse.

2. What are things should I do if I want the driver to work on alpha
platform also.


Thanks

-Pran
