From user space access, use mmap.(Note that it won't work for RAM, but that's not what you're trying to do anyways.)
I misunderstood something here; you can in fact remap RAM via /dev/mem. This mapping will be done with the VM_RESERVED flag set, which was not acceptable in the context I heard it discussed, but I guess is ok generally speaking. -- Hollis Blanchard IBM Linux Technology Center ** Sent via the linuxppc-dev mail list.
