This patch series makes the current KVM device passthrough code generic enough so that other IOMMU implementation can also plug into this code. It works by factoring the functions Vt-d code exports to KVM into a generic interface which allows different backends.
This is the third version of the patchset. I rebased these patches onto the 13-patches post of Han Weidongs multiple device assignment work and included changes to the commit-messages according the comments I got from the review. This a basic implementation of a generic interface. It can and should be improved later to support more types of hardware IOMMUs then VT-d and AMD IOMMU. Since I have no VT-d hardware available these patches are only compile tested for now. Please review, comment and test these patches.
