Hi all


Does anyone have the manual for Quality of service controller (QoSC) ?


My customer want to check the priority of AXI bus for i.MX7D.

Because When using SDMA, the output image of MIPI DSI was distorted.
So I doubt the priority of AXI.


I understand the QoSC control the priority of the AXI bus.

However, there are no explanation about it.


Could you tell me the detail of the QoSC and how to check the priority of the AXI ?
