Hi Alex,

Here is a draft task list after a short discussion w/ Kevin,
would you please have a look?

	Bus Driver

		{ in i915/vgt/xxx.c }

		- define a subset of vfio_pci interfaces
		- selective pass-through (say aperture)
		- trap MMIO: interface w/ QEMU

	IOMMU

		{ in a new vfio_xxx.c }

		- allocate: struct device & IOMMU group
		- map/unmap functions for vgpu
		- rb-tree to maintain iova/hpa mappings
		- interacts with kvmgt.c


	vgpu instance management

		{ in i915 }

		- path, create/destroy


--
Thanks,
Jike
