[RFC v2 00/22] intel_iommu: expose Shared Virtual Addressing to VM

2019-10-24 Thread Liu Yi L
Shared virtual address (SVA), a.k.a, Shared virtual memory (SVM) on Intel platforms allow address space sharing between device DMA and applications. SVA can reduce programming complexity and enhance security. This series is intended to expose SVA capability to VMs. i.e. shared guest application add
