+         The PCI device backend driver allows the kernel to export arbitrary
+         PCI devices to other guests. If you select this to be a module, you
+         will need to make sure no other driver has bound to the device(s)
+         you want to make visible to other guests.
+
+         The parameter "passthrough" allows you specify how you want the PCI
+         devices to appear in the guest. You can choose the default (0) where
+         PCI topology starts at 00.00.0, or (1) for passthrough if you want
+         the PCI devices topology appear the same as in the host.
+
+         The "hide" parameter (only applicable if backend driver is compiled
+         into the kernel) allows you to bind the PCI devices to this module
+         from the default device drivers. The argument is the list of PCI BDFs:
+         xen-pciback.hide=(03:00.0)(04:00.0)
+
+         If in doubt, say m.
