The `SDID` field identifies the supervisor domain whose memory is accessed by
this transaction.

The `SRL` and `SML` fields along with `operand-1.SSM` field are used to determine
the effective `RCID` and `MCID` provided by the IOMMU for device originated
requests. The determination of the effective `RCID` and `MCID` is as specified
by <<SMQOSID>>. The `SQRID` identifies the QRI for requests originating from the
devices associated with the SD and accompanies the `RCID` and `MCID` in the
requests made by the device to the QRI.
