Qdma xilinx.
Unfortunately, we just found out that not all ultrascale+ devices with PCIe blocks can support QDMA. This seems to be the case with the xczu5ev-sfvc784-1-i, as QDMA does not appear in the IP catalog. I even tried swapping the part in the ZCU-106 design to the xczu5ev chip, but this caused a bunch of errors saying that the xczu5ev chip does not ...

Xilinx provides a DPDK poll mode driver based on DPDK v18.11 that runs on a PCI Express root port host PC to interact with the QDMA endpoint IP via PCI Express.
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.
