Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Date: Thu, 08 Oct 1998 11:14:40 -0500 From: Chris Csanady Sender: owner-freebsd-alpha@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I have come across a couple of things while trying to port a driver to the alpha, and was wondering if someone has any insight. First of all.. Is there any way to determine the address length at preproccessor time? Also, on the alpha--what is the proper way to deal with the bus addresses? In particular, are the phsical addresses mapped into 32 bits somehow for the pci bus? I have some 64 bit pci cards and was wondering what would be the best way to handle this.
