Introduction This page gives an overview of AXI PCIe Root Complex driver for the Xilinx AXI PCIe Soft IP, which is available as part of the Zynq and Microblaze Linux distributions. AXI PCIe Soft IP PCI Express (abbreviated as PCIe) is the newest bus standard designed to replace the old PCI/PCI-X and AGP standards. Queue DMA subsystem for PCI Express (Vivado 2019.1) - QDMA Linux Kernel Driver Usage and Debug Guide
I have looked at the Xilinx XDMA driver. But they explicitly state that that's only guaranteed to work on x86 systems. One explanation for that I found was that ARM systems may not be cache coherent, and if the FPGA-as-DMA shoves data into the RAM, the CPU might still used old, cached data.
