xpci —
xpci* at xenbus?
pci* at xpci?
xpci driver is the frontend part of the PCI
pass-through functionality that can be used by Xen guest domains to
communicate with PCI devices.
From a guest point of view, xpci is
similar to a pci(4) bus, except
that the guest talks with the PCI backend driver instead of the real
physical device directly.
When the host domain is NetBSD, the
xpci driver is backed by a
pciback(4) driver within the
dom0.
xpci driver first appeared in
NetBSD 5.1.
xpci driver was written by Manuel
Bouyer
