Re: [Xen-devel] Ping: [PATCH v5] AMD IOMMU: fix Dom0 device setup failure for host bridges

Okay, understand. The change doesn't impact VT-d side, although some lines are 
actually added. Looks good to me, thanks!

Right, but that's not the question. The issue is that for the AMD side we need 
the new device type, and the question is whether the handling done by Suravee's 
patch for VT-d is correct. I.e.
we're asking for your review of the (unavoidable) VT-d changes in that patch.
