[PATCH] vfio powerpc: implement IOMMU driver for VFIO

2013-03-19 Thread Alexey Kardashevskiy
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 patch implements an IOMMU driver for VFIO which does map
