Enable Quality of Service (QoS) blocks for Display SubSystem (DSS), by servicing the DSS - DDR traffic from the Real-Time (RT) queue. This is done by setting the DSS DMA orderID to 8. The C7x and VPAC have been overwhelming the DSS's access to the DDR (when it was accessing via the Non Real-Time (NRT) Queue), primarily because their functional frequencies, and hence DDR accesses, were significantly higher than that of DSS. This led the display to flicker when certain edgeAI models were being run. With the DSS traffic serviced from the RT queue, the flickering issue has been found to be mitigated. The am62a qos files are auto generated from the k3 resource partitioning tool. Section-3.1.12, "QoS Programming Guide", in the AM62A TRM[1], provides more information about the QoS, and section-14.1, "System Interconnect Registers", provides the register descriptions.
