OK, This is the URL for a sample module that implements the mmap device entry point in order to share pages of host memory with a process. It took a lot of digging to figure out how to do this reliably, so start here before trying to figure it out for yourself:-)

I've only tested it on Linux/Intel. It is heavily commented to explain what I think is going on each step of the way.
Comments, corrections welcome. -- Steve Williams steve@icarus.com steve@picturel.com
