The application program initiates the C2H transfer, with transfer length and receive buffer location. The Driver starts the C2H transfer by writing the number of PIDX credits to AXI-ST C2H PIDX direct address 0x18008 (for Queue 0). to initiate data transfer C2H streaming from FPGA to host solely from FPGA fabric (without dma-from-device ...

For this case, if CIDX is 0, the maximum PIDX update would be 6. In the example above, if traffic has already started and the CIDX is 4, the maximum PIDX update is 3. Available descriptors are always <ring size> - 2. At any time, the software should not update the PIDX to more than <ring size> - 2. For example, if queue size is 8, which ...
