The VFIO documentation is slightly out of date. This minor correction
replaces references to VFIO_IOMMU_X86 with the correct reference to

This is a workaround to make the VFIO_IOMMU_TYPE1 driver usable with
platform devices instead of PCI. A future permanent fix should support
both. This is required in order to use the Exynos SMMU, or ARM SMMU
driver with VFIO.

A VFIO userspace driver will start by opening the VFIO device
that corresponds to an IOMMU group, and will use the ioctl interface
to get the basic device info, such as number of memory regions and
interrupts, and their properties.

This is a preview of the base work, towards VFIO support on ARM platforms

Patch written by Antonios Motakis a.mota...@virtualopensystems.com:
IOMMU groups are expected by certain users of the IOMMU API,
e.g. VFIO. Since each device is behind its own System MMU, we
can allocate a new IOMMU group for each device.

The patches have been compile tested for x86, ARM and PPC
and runtime tested on x86 (Intel VT-d and AMD IOMMU).
Please review.
