This patchset provides IOMMU driver support of shared virtual memory (SVM) virtualization. Generic APIs are introduced in addition to Intel VT-d specific changes, the goal is to have common interfaces across IOMMU and device types for both VFIO and other in-kernel users.
This is the IOMMU portion follow up of the more complete series of the kernel changes to support SVM. Please refer to the link below for more details. https://www.spinics.net/lists/kvm/msg148819.html New in this series are the IOMMU fault notification APIs. At the top level, three new IOMMU interfaces are introduced: - bind PASID table - passdown invalidation - per device IOMMU fault notification The additional patches are Intel VT-d specific, which either implements or replaces existing private interfaces with the generic ones.
