Suravee Suthikulpanit (2):
hw/i386/amd_iommu: Isolate AMDVI-PCI from amd-iommu device to allow
full control over the PCI device creation
hw/i386/amd_iommu: Allow migration when explicitly create the
AMDVI
Add migration support for AMD IOMMU model by saving necessary AMDVIState
parameters for MMIO registers, device table, command buffer, and event
buffers.
Also change devtab_len type from size_t to uint64_t to avoid 32-bit build
issue.
