In order to move the discussion along productively, please have a look at git://repo.or.cz/qemu/rth.git axp-iommu-1 which is based on your previous patch set. There's stuff in there that's not 100% relevant to the discussion, but these two commits: 0652a74 target-alpha: Implement iommu translation for Typhoon. db50b11 DMA: Use an void* opaque value, rather than upcasting from qdev. are exactly what I'm interested in discussing. r~ -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
