| 2013-12-30 | powerpc/iommu: Update constant names to reflect their hardcoded page size |   Alistair Popple | |
| The powerpc iommu uses a hardcoded page size of 4K. This patch changes the name of the IOMMU_PAGE_* macros to reflect the hardcoded values. A future patch will use the existing names to support dynamic page sizes.

| 2013-06-20 | powerpc/vfio: Implement IOMMU driver for VFIO |   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 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).
