With the Cyclone V SoC, how can I use the FPGA fabric to access the HPS DMA?

Hello everyone,

I want to make something that records values that are in my FPGA. I thought of using the Cyclone V SoC DMA, I do have the Altera SoC kit.

With the Cyclone V SoC, how can I use the FPGA fabric to access the HPS DMA? I want to set a trigger in the HPS DMA, so that when I send a signal to high level at FPGA Fabric, the DMA starts to copy a FPGA FABRIC RAM content to the DDR connected in the HPS and visible by the Linux running in the ARM.

*Is this the easiest/fastest way of achieving what I want?
