From 5ffd229c02731a91d08ca21e76b503c5bbb5c095 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Tue, 21 May 2013 13:33:10 +1000 Subject: powerpc/vfio: Implement IOMMU driver for VFIO VFIO implements platform independent stuff such as a PCI driver, BAR access (via read/write on a file descriptor or direct mapping when possible) and IRQ signaling. The platform dependent part includes IOMMU initialization and handling. This implements an IOMMU driver for VFIO which does mapping/unmapping pages for the guest IO and provides information about DMA window (required by a POWER guest).
