Struct dmar::DmarDrhd

pub struct DmarDrhd<'t> { /* private fields */ }

DRHD: DMAR Hardware Unit Definition Structure.

This table is described in Section 8.3 of the VT Directed I/O Spec.

Implementations

impl<'t> DmarDrhd<'t>

pub fn iter(&self) -> DrhdIter<'t>

Returns an Iterator over the DmarDeviceScope entries in this DRHD, which are variable in both number and size.

pub fn include_pci_all(&self) -> bool

Returns the value of the INCLUDE_PCI_ALL flag, the only bit flag in this DRHD table.

Description from Intel Spec

If false, this remapping hardware unit has under its scope only devices in the specified segment that are explicitly identified through the Device Scope field. The device can be of any type as described by the Type field in the Device Scope Structure including (but not limited to) IOAPIC and HPET.

If true, this remapping hardware unit has under its scope all PCI compatible devices in the specified segment, except devices reported under the scope of other remapping hardware units for the same segment. As such, one can use the Device Scope structures to enumerate IOAPIC and HPET devices under its scope.

pub fn segment_number(&self) -> u16

Returns the PCI segment number associated with this DRHD.

pub fn register_base_address(&self) -> u64

Returns the base address of this DRHD’s remapping hardware register set.
