Attached is EPT/VT-d page table sharing patch I mentioned earlier. Basic idea is to leverage 2MB and 1GB page size support in EPT by having VT-d using the same page tables as EPT. When EPT page table changes, flush VT-d IOTLB cache. We are still further testing this patch but would appreciate feedbacks.
