[PATCH 2/2] vfio powerpc: implemented 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 patch implements an IOMMU driver for VFIO which does map

[PATCH 1/2] vfio powerpc: enabled on powernv platform

This patch initializes IOMMU groups based on the IOMMU configuration discovered during the PCI scan on POWERNV (POWER non virtualized) platform. The IOMMU groups are to be used later by VFIO driver (PCI pass through). It also implements an API for mapping/unmapping pages for guest PCI drivers and

[PATCH 0/2] vfio on power: yet another try

The set includes 2 patches. The first one adds necessary support for VFIO IOMMU support, the second one adds a SPAPR TCE IOMMU driver to VFIO. At the moment we have decided to get rid of DMA64 window properties because we need more API than just 2 properties (such as dynamic window allocation) bu
