Re: [Xen-devel] Re: Fire-wire passthrough with Linux pv-ops (2.6.31.1)

["Mr. Teo En Ming (Zhang Enming)" <space.time.universe@xxxxxxxxx>]

Couldn't pci-stub be used to passthrough the ohci firewire controller?
I had used pci-stub to passthrough the PCI-E x16 graphics card to
Windows guest.

For firewire controller, must it really use pciback for passthrough?
