[PATCH v4 0/2] hw/i386/amd_iommu: Add migration support

Posted by Suravee Suthikulpanit 11 months, 1 week ago

Currently, amd-iommu device does not support migration. This series addresses
an issue due hidden AMDVI-PCI device enumeration. Then introduces migratable
VMStateDescription, which saves necessary parameters for the device.

Changes from v2:
(https://lore.kernel.org/all/20250212054450.578449-1-suravee.suthikulpanit@amd.com)
  * Patch 1: Fix build error
  * Patch 2: Fix 32-bit build issue.

Changes from v2:
(https://lore.kernel.org/all/20250206051856.323651-1-suravee.suthikulpanit@amd.com)
  * Add patch 1/2

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-PCI device
