[Xen-devel] Xen Platform Device and dom0

[Have_Quick <have_quick@xxxxxxxxx>]

Hello, I'm wondering how one would communicate with the Xen Platfrom Device created with xen_platform.c from within dom0. From domU it seems relatively straightforward to map the resources and read or write to it, however I am confused as to how this would be accomplished from dom0. I guess the root of my confusion is to how qemu devices are handled by the hypervisor, obviously there must be a way to get information out of qemu otherwise things like the emulated network card would not be useful but I'm having trouble understanding how this works. A pointer to the right direction would be very appreciated, thanks.
