The transfer controller plays an important role in handling proxy memory protection. There are two access properties associated with a transfer: for instance, the privilege id (system-wide identification assigned to a controller) of the controller initiating the transfer, and the privilege level (user versus supervisor) used to program the transfer. This information is maintained in the PaRAM set when it is programmed in the channel controller. When a TR is submitted to the transfer controller, this information is made available to the EDMA_TPTC and used by the EDMA_TPTC while issuing read and write commands. The read or write commands have the same privilege identification, and privilege level as that programmed in the EDMA transfer in the channel controller.
