[Xen-devel] [rfc 0/4] ioemu: specify the slot for pass-through devices

[Simon Horman <horms@xxxxxxxxxxxx>]

[ I am "reposting" these because yesterday's initial post
  never made it off my PC ]

Currently a slot may be specified for a hot-plug device,
but not for a pass-through device that is inserted at boot time.
This patch adds support for the latter.

The syntax is:
     BUS:DEV.FUNC[@VSLOT]
     e.g: 0000:00:1d:0@7

This may be important as recent changes that allow any free PCI slot to be
used for pass-through (and hotplug) may case pass-through devices to be
assigned in different locations to before. Amongst other things, specifying
the slot will allow users to move them back, if there is a need.

These changes need the patches that I posted today as the series
"[patch 0/2] ioemu: Allow any unused PCI device to be used for
pass-through"

There is also a xend portion of this patch, which will be posted separately.
