This series adds Mediated device support to v4.6 Linux host kernel. Purpose of this series is to provide a common interface for mediated device management that can be used by different devices. This series introduces Mdev core module that create and manage mediated devices, VFIO based driver for mediated PCI devices that are created by Mdev core module and update VFIO type1 IOMMU module to support mediated devices. What's new in v4? - Renamed 'vgpu' module to 'mdev' module that represent generic term 'Mediated device'. - Moved mdev directory to drivers/vfio directory as this is the extension of VFIO APIs for mediated devices. - Updated mdev driver to be flexible to register multiple types of drivers to mdev_bus_type bus. - Updated mdev core driver with mdev_put_device() and mdev_get_device() for mediated devices. What's left to do? VFIO driver for vGPU device doesn't support devices with MSI-X enabled. Please review.
