I  now  have  a  working implementation of my own pcifront based on the
mini-os  implementation,  however I can't seem to find any examples or
documentation  anywhere on how to discover and map the PCI device into
my PV memory map.

Checking  the  Linux  pcifront  driver it seems to be doing IO via the
pciback  driver. This won't work in my situation, I need raw access to
the PCI device memory.

Looking  at  the  GPLPV  drivers as well to see if I can decipher from
them how to do this.

Any suggestions on how to implement direct access to the PCI device?
