[PATCH 0/6] IOMMU/DMA map_resource support for peer-to-peer

2015-05-01 Thread wdavis
From: Will Davis Hi, This patch series adds DMA APIs to map and unmap a struct resource to and from a PCI device's IOVA domain, and implements the AMD, Intel, and nommu versions of these interfaces. This solves a long-standing problem with the existing DMA-remapping interfaces, which require th
