[Xen-devel] PCI Passthru: fn0 exported but not fn1

[Jambunathan K <jambunathan@xxxxxxxxxx>]

Given the following device list,  I am exporting one of the functions to
Dom1 through PCI passthrough.

$ lspci | grep known
04:00.0 Ethernet controller: Unknown device 4040:0002 (rev 25)
04:00.1 Ethernet controller: Unknown device 4040:0002 (rev 25)
04:00.2 Ethernet controller: Unknown device 4040:0002 (rev 25)
04:00.3 Ethernet controller: Unknown device 4040:0002 (rev 25)

If I export just 04:00.0,  it is visible ('lspci') in Dom1. However if I
export just 04:00.1 then it is no more visible in Dom1.

I am using Xen310. As an additional information, I am seeing this
behaviour on my 'new box'. Things were fine on my earlier box. It is
possible that this is a platform specific thing.

If it is a known issue, I would be happy to patch my tree. Otherwise I
can debug this further post some debug logs for your scrutiny.
