I'm new to xen and these days I try to do something with the gntdev, but I don't know how exactly gntdev works.....
It appears that I need to pass grant ref from the GOS in the user space....
I need some instruction on gntdev and a example on memory maping using gntdev would be helpful

thanks in advance
