[PATCH 6/7] vfio: moving some functions in common file

Some function defined in vfio_iommu_type1.c were common and we want to use these for FSL IOMMU (PAMU) and iommu-none driver. So some of them are moved to vfio_iommu_common.c I think we can do more of that but we will take this step by step. Signed-off-by: Bharat Bhushan bharat.bhus

[PATCH 0/9 v2] vfio-pci: add support for Freescale IOMMU (PAMU)

From: Bharat Bhushan bharat.bhus...@freescale.com PAMU (FSL IOMMU) has a concept of primary window and subwindows. Primary window corresponds to the complete guest iova address space (including MSI space), with respect to IOMMU_API this is termed as geometry. IOVA Base of subwindow is determined

[PATCH 5/9 v2] pci/msi: interface to set an iova for a msi region

This patch defines an interface by which a msi page can be mapped to a specific iova page. This is a requirement in aperture type of IOMMUs (like Freescale PAMU), where we map msi iova page just after guest memory iova address. Signed-off-by: Bharat Bhushan bharat.bhus...@freescale.com --- v2
