Hi, 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 second version of the patchset. The most important change to the previous version is that this patchset was rebased to the improved API from Han Weidong which supports multiple devices per IOMMU domain. For completeness, this series also includes the patches from Han with some cleanups. So this patchset can be applied on current avi/master tree. For testing this code can also be pulled against avi/master tree from git://git.kernel.org/pub/scm/linux/kernel/git/joro/linux-2.6-iommu.git iommu-api 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.
