How is A10 MSGDMA prefetch enabled core to transfer 128 descptors data from FPGA to CPU?

hello ,

We use Arria10 on our customer board.

In our System, we need implement mSGDAM Core to transfer a bundle of 128 descriptors for data moving from cpu to fpga device . I checked " ug_embeded" user guide, but still not clear about " HOW can mSGDMA perfetch IP realize this "。 What's the procedure to implement this ？

Is there an exampel for mSGDMA prefetched enabled design ? We use Linux on CPU 。

Thanks in advance ~
