Struct AcpiSmmuConfig 

pub struct AcpiSmmuConfig {
    pub rc_index: u32,
    pub segment: u16,
    pub base: u64,
    pub event_gsiv: u32,
    pub gerr_gsiv: u32,
    pub reserved_iova_ranges: Vec<MemoryRange>,
}

Configuration for the SMMUv3 ACPI IORT node.

Fields

rc_index: u32

Index of the root complex this SMMU covers (matches PcieHostBridge.index). Used to route each RC’s IORT ID mapping to its specific SMMU node.

segment: u16

PCIe segment number of the root complex this SMMU covers. Used as the output_base in the SMMU→ITS ID mapping to produce globally unique ITS device IDs: (segment << 16) | BDF.

base: u64

MMIO base address of the SMMU.

event_gsiv: u32

GIC SPI INTID for the event queue interrupt.

gerr_gsiv: u32

GIC SPI INTID for the global error interrupt.

reserved_iova_ranges: Vec<MemoryRange>

IOVA ranges reserved by the host IOMMU (e.g., MSI windows). When non-empty, an IORT RMR node (or DT reserved-memory entry) is generated so the guest identity-maps these ranges in its S1 page tables.
