Parsed IVHD (I/O Virtualization Hardware Definition) block.

Describes one AMD IOMMU hardware unit and the devices behind it.

Fields

typ: IvhdType

IVHD type (0x10 = legacy, 0x11 = extended).

flags: IvhdFlags

Flags.

length: u16

Length of this IVHD block (including device entries).

device_id: u16

PCI device ID of the IOMMU itself.

capability_offset: u16

Offset into PCI capability space for the IOMMU capabilities.

ioapic_id: u8

I/O APIC ID associated with this IOMMU.

iommu_base: u64

Physical base address of the IOMMU registers.

pci_segment: u16

PCI segment group.

mmio_base: Option<u64>

MMIO base address (only for extended type 0x11).

device_entries_off: u64

Raw pointer to the first device entry in this block.

device_entries_len: usize

Length available for device entries.
