Module dmar 

DMAR (DMA Remapping Reporting Structure) types for Intel VT-d discovery.

The DMAR ACPI table describes Intel VT-d remapping hardware to the guest OS. It contains one or more DRHD (DMA Remapping Hardware Unit Definition) structures, each describing a single VT-d remapping unit: its MMIO base, PCI segment, and the set of devices behind it via device scope entries.

Reference: Intel Virtualization Technology for Directed I/O Architecture Specification, Document 774206, §8.
