Xen devel - Mar 2010 - IOMMU support in Xen

I am trying to find out what support exists today for hardware IOMMUs in Xen. 
In particular, I am interested in how the IOMMU support is used in guest and
driver domains.

Any information (including pointers to the source code or documents) will be
much appreciated.

Thanks.

AMD + Intel.

Google for "Intel VT-D specification". Take a look at
http://download.intel.com/technology/computing/vptech/Intel(r)_VT_for_Direct_IO.pdf

or  http://developer.amd.com/documentation/articles/pages/892006101.aspx
