However, it seems that the QDMA IP supports ATS capability on PF0 only. Are there any ways to enable ATS capability on VFs? If I can configure the PCIe configuration space for VFs, it might be possible.

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 ...QDMA Ethernet Platform.
