XPCI(4)               NetBSD/xen Kernel Interfaces Manual              XPCI(4)


NAME
xpci -- Xen frontend paravirtualized PCI pass-through driver
SYNOPSIS
xpci* at xenbus? pci* at xpci?
DESCRIPTION
The xpci driver is the frontend part of the PCI pass-through functional- ity 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.
SEE ALSO
pci(4), pciback(4), xenbus(4)
HISTORY
The xpci driver first appeared in NetBSD 5.1.
AUTHORS
The xpci driver was written by Manuel Bouyer <bouyer@NetBSD.org>.
SECURITY CONSIDERATIONS
As PCI passthrough offers the possibility for guest domains to send arbi- trary PCI commands to a physical device, this has direct impact on the overall stability and security of the system. For example, in case of erroneous or malicious commands, the device could overwrite physical mem- ory portions, via DMA. NetBSD 9.0 January 8, 2011 NetBSD 9.0
