Hello, I am working on implementing a low level message passing protocol for FreeBSD, although I have a few questions. First, I was wondering if it is possible given a physical address, to copy data to it from a virtual address. Or is a virtual mapping necessary? The other question is how may I map user pages into the kernel? I've looked through vm_map.c, and it seems that support for this is lacking. To get around this for now, I am attempting to use almost exclusively physical address--although am now sure how it will work out.
