Struct IntelVtdDmarConfig 

pub struct IntelVtdDmarConfig {
    pub host_address_width: u8,
    pub units: Vec<IntelVtdAcpiConfig>,
    pub ioapic_rid: Option<u16>,
}

DMAR-level configuration for Intel VT-d ACPI table generation.

Groups the DMAR header fields with the per-unit configs.

Fields

host_address_width: u8

Host address width in bits (e.g. 48). DMAR HAW field = width - 1.

units: Vec<IntelVtdAcpiConfig>

Per-unit configurations, one per root complex with an Intel VT-d unit.

ioapic_rid: Option<u16>

IOAPIC PCIe Requester ID (RID) for the DMAR IOAPIC device scope.

When set, a DEVICE_SCOPE_IOAPIC entry is added to the DRHD whose segment (0) and start bus cover this RID, so the guest can locate the IOAPIC’s source ID for interrupt remapping.
