* | powerpc/vfio: Implement IOMMU driver for VFIOAlexey Kardashevskiy2013-06-201-0/+63
|/ | | | | | | | | | | | | | | | | | 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).
