xilinx_axidma
A zero-copy Linux driver and a userspace interface library for Xilinx's AXI DMA and VDMA IP blocks. These serve as bridges for communication between the processing system and FPGA programmable logic fabric, through one of the DMA ports on the Zynq processing system.

Petalinux <---> FPGA using DMA
I recently got this kind of working, using this driver https://github.com/bperez77/xilinx_axidma. Even after using this driver I had to make changes to the auto generated device tree to get it up and running. This driver also comes with a userspace library and examples that work. I was unable to get the axidmatest.c provided by Xilinx to work.

Petalinux <---> FPGA using DMA
I started off by using udmabuf to map regions of my memory to the userspace ensuring that there are no conflicts with the kernel and app.

Petalinux and DMA with Xilinx SoC
Install the u-dma-buf kernel module to map a section of your virtual address space to be contiguous in your physical address space.

[BEGINNER] How to send Ethernet packets from HPS to FPGA on Cyclone V ? (DMA)
Lastly, what I think would be the way - DMA so that the CPU doesn't really have to copy each and every packet into RAM - but I have no idea how to go about this, but I've seen some syscalls that shall be able to tell Linux to actually 'put' packets there (I really am a beginner, sorry guys, I'm trying my best tho!). And I've had a slight experience with u-dma-buf kernel module (https://github.com/ikwzm/udmabuf), which might be the place we wanna Linux to put packets to. Then, we'd give the FPGA the address of the buffer allocated by u-dma-buf and it would simply start the processing from there. Is that correct or am I missing something ?
