Qdma xilinx.
We recommend qdma for lower latency, we recommend the ethernet ports for consistent latency as there is high overhead for PCIe. It doesn't look like there is a QDMA shell coming for the U280, you should contact your xilinx marketing or sales rep to see if there are any Ethernet enabled shells.

I would like to use the QDMA shell rather than the XDMA shell, as the host to kernel axi streaming interface is a better fit for our existing RTL design than the AXI master interface to DDR. UG1238 (v2019.1) - SDAccel Development Environment states that the U200 supports both "xilinx_u200_qdma_201830_1" and "xilinx_u200_qdma_201910_1" shells ...I have had to make few patches to compile using Yocto for kernel 5.15 for ARM (attached in xilinx_dma.diff) I have run the qdma_run_test_pf.sh together with datafile_16bit_pattern.bin with one queue only and it works for MM H2C and C2H and with ST H2C. It does not with C2H ST.The patch resolves the issue for us. Once applied, the "impossible" timeouts are no longer seen. I'm not working on this code any more, but if your current driver doesn't have this or an equivalent change then I would expect it to show the same problem at least sometimes, with a greater chance of problems in multithreaded programs.The QDMA driver identifies the device, and starts to initialize the contexts, but always freezes at `sel = 2` (`QDMA_CTXT_SEL_HW_C2H`).
