DMA vs MSGDMA

I am really talking about HPS system. I have the Linaro Linux with my C application. Application is a server that receives images from client over Ethernet. Images are not stored in a flash file system, they are in main memory, ready to DMA'ing to FPGA. (After performing the image processing I will want to DMA data back to the HPS )

I attach a file from Qsys. I will be grateful if you take a look at it and tell me if DMA will work.

I am doing a HPS FPGA project the first time and I'm a little lost in this topic.
