I'll point the individual at you and the iommu mailing list, and the CCs. Sadly, I did not write down the full question, nor the person's name (from Microsoft, possibly?) and now seem to have completely forgotten both (it's been a long few months...). If I can find something in the meeting minutes, I'll pass that on. Thanks again for everyone's patience. -- ciao, al ----------------------------------- Al Stone Software Engineer Red Hat, Inc. ahs3@redhat.com -----------------------------------
