Re: [Xen-devel] [PATCH v4] igd-passthrough-i440FX: convert to realize()

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Since you are at it, could you please let me know how well igd
passthrough works without this bugfix:

http://marc.info/?l=qemu-devel&m=145172165010604

which is about to land in QEMU.  I guess it doesn't work at all?

I am asking because I would like to know the level of support we need to
provide to igd passthrough with the latest QEMU release (2.5).
