This series adds vGPU support to v4.6 Linux host kernel. Purpose of this series is to provide a common interface for vGPU management that can be used by different GPU drivers. This series introduces vGPU core module that create and manage vGPU devices, VFIO based driver for vGPU devices that are created by vGPU core module and update VFIO type1 IOMMU module to support vGPU devices. What's new in v3? VFIO type1 IOMMU module supports devices which are IOMMU capable. This version of patched adds support for vGPU devices, which are not IOMMU capable, to use existing VFIO IOMMU module. VFIO Type1 IOMMU patch provide new set of APIs for guest page translation. What's left to do? VFIO driver for vGPU device doesn't support devices with MSI-X enabled. Please review.
