I took the PCI Device example from the "FreeBSD Architecture Handbook"
as the base, and I added the necessary functionality for BAR and other
memory mapping. I created also a user-sapce tool, which connects to the
PCI device driver by ioctl() and mmap(), and prints some results.

I prepared a .zip-Archive containing these files, and a Makefile for
the device driver.


Enhanced sources for mypci device driver:

Original sources for mypci device dirver:

If you have questions, then please don't hesitate to send a note to this
thread on this list.

Best regards
