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

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

Hi Konrad,

So if I try firewire passthrough in pvops dom0 kernel 2.6.30-rc3 it
will not work also because the code for firewire controller
passthrough is non-existent as of now?
