Link Status: Check Link Status in lspci to ensure the link is operating at full speed and width. **BEST SOLUTION** Hi, Did you check which interrupt mechanism does dma use? And also xdma driver can be built with poll mode option. Select one of three options for data transport from host to user logic, or user logic to host. 0 (CPM) including DMA (QDMA) and two PCIe Controllers 0 & 1, is hardened in Versal ACAP devices. *Please note that this driver and associated software are supplied to give a basic generic reference implementation only. From Windows: Start > All Programs > Xilinx Design Tools > Xilinx Software Command Line Tool 2018. I'll start with the block diagram of my design. A PCIe DMA translates the stream of . Wupper is specifically designed for the 256 bit wide AXI4-Stream interface of the Xilinx Virtex-7 FPGA Gen3 Integrated Block for PCI Express (PCIe). I suspect you need a PCIe to AXI4 Streaming Bridge (in effect, logic to turn a DMA channel with address into sink and sources of streaming data). Zynq UltraScale+ MPSoC PS-PCIe End Point Driver - Xilinx Wiki - Atlassian PCIe Tips and Tricks - Xilinx Wiki - Confluence Jason Lawley, a Xilinx expert to PCIe application has a great tutorial on getting the best performance with Xilinx’s DMA engine.
