Definitions for the DMAR, the Direct Memory Access (DMA) Remapping ACPI table.

The structures defined herein are based on Section 8 of Intel’s VT Directed I/O Spec: https://software.intel.com/content/www/us/en/develop/download/intel-virtualization-technology-for-directed-io-architecture-specification.html

Structs

  • DeviceScopePath
  • Dmar
    A wrapper around the DMAR ACPI table ([DmarReporting]), which contains details about IOMMU configuration.
  • DmarAndd
    ANDD: DMAR ACPI Name-space Device Declaration Structure.
  • DmarAtsr
    ATSR: DMAR Root Port ATS (Address Translation Services) Capability Reporting Structure.
  • DmarDeviceScope
    DMAR Device Scope Structure.
  • DmarDrhd
    DRHD: DMAR Hardware Unit Definition Structure.
  • DmarEntryRecord
    Represents the “header” of each dynamic table entry in the [DmarReporting] table.
  • DmarIter
    An Iterator over the dynamic entries of the Dmar. Its lifetime is dependent upon the lifetime of its Dmar instance, which itself is bound to the lifetime of the underlying [AcpiTables].
  • DmarRhsa
    RHSA: DMAR Remapping Hardware Static Affinity Structure.
  • DmarRmrr
    RMRR: DMAR Reserved Memory Region Reporting Structure.
  • DmarSatc
    SATC: DMAR SoC Integrated Address Translation Cache Reorting Structure.
  • DrhdIter
    An Iterator over the dynamic entries (DmarDeviceScopes) of the DmarDrhd. Its lifetime is dependent upon the lifetime of its DmarDrhd instance, which itself is bound to the lifetime of the underlying [AcpiTables].

Enums

  • DmarEntry
    The set of possible sub-tables that can exist in the top-level DMAR table.

Constants

Functions

  • handle
    The handler for parsing the DMAR table and adding it to the ACPI tables list.
