You're making life far too hard for yourself. FreeBSD doesn't reward you for trying to kludge things; the infrastructure you're looking for wants you to be using our bus interfaces. Have a look at pmap_mapdev() for what you're trying to do. > Take your average run-to-the mill PCI network driver... like FPA or FXP.

You're picking bad examples to work with, since both those drivers support multiple operating systems. Try a much cleaner driver like, eg. if_tl. -- \\ The mind's the standard \\ Mike Smith \\ of the man. \\ msm...@freebsd.org \\ -- Joseph Merrick \\ msm...@cdrom.com To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
