[PATCH v4 10/15] iommu/vt-d: Probe DMA-capable ACPI name space devices

2019-05-24 Thread Lu Baolu
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
