[RFC v10 00/25] intel_iommu: expose Shared Virtual Addressing to VMs

2020-09-10 Thread Liu Yi L
Shared Virtual Addressing (SVA), a.k.a, Shared Virtual Memory (SVM) on Intel platforms allows address space sharing between device DMA and applications. SVA can reduce programming complexity and enhance security. This QEMU series is intended to expose SVA usage to VMs. i.e. Sharing guest applicati
