iommu/vt-d: Probe DMA-capable ACPI name space devices

Browse source

Some platforms may support ACPI name-space enumerated devices
that are capable of generating DMA requests. Platforms which
support DMA remapping explicitly declares any such DMA-capable
ACPI name-space devices in the platform through ACPI Name-space
Device Declaration (ANDD) structure and enumerate them through
the Device Scope of the appropriate remapping hardware unit.
