> This allows the upper layers to set a domain to a PASID of a device
> if the PASID feature is supported by the IOMMU hardware. The typical
> use cases are, for example, kernel DMA with PASID and hardware
> assisted mediated device drivers.
>
> The attaching device and pasid information is tracked in a per-domain
> list and is used for IOTLB and devTLB invalidation.
