[Xen-devel] [PATCH 00 of 16] [RFC] amd iommu: support ATS device passthru on IOMMUv2 systems
ATS devices with PRI and PASID capabilities can communicate with iommuv2 to
do 2 level (nested) DMA translation and IO demand paging. To do that, both
iommu driver and ats device have to been enabled in guest OS. This patch set
adds initial iommu emulation for hvm guests to support ATS device passthru.
Please review.
Thanks,
Wei
