Verify IOMMU presence and configuration

  • Article

This test does the following validation:

  1. Ensures that at least one IOMMU device is present on the system
  2. Ensure that Virtualization-based Security (VBS) is disabled on the system
  3. Performs basic validation of the IOMMU ACPI tables (DMAR/IVRS) looking for simple inconsistencies and/or divergence from the IOMMU specs
  4. Performs basic validation to ensure that there are no inconsistencies in how IOMMUs are reported in the MADT table vs. in the DMAR/IVRS tables
