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.

Probably rather late for you, but I think there's a bug in qdma_request_wait_for_cmpl()-- it shouldn't assume /** if the call back is not done, request timed out */ as qdma_waitq_wait_event_timeout() is actually wait_event_interruptible(), which can return early if there's a signal pending!But …make. sudo make install. sudo make install-mods. sudo modprobe qdma. shutdown -r now.

With MDMA_PFCH_CACHE_DEPTH=16, less than 15 active queues work flawlessly. 2. When more than 15 queues are “activated” (at the same time or at random times) C2H CMPT interface breaks. Activated here simple means C2H received at least one packet with that QID. 3. Running the DPDK software test application. The below steps describe the step by step procedure to run the DPDK QDMA test application and to interact with the QDMA PCIe device. Navigate to examples/qdma_testapp directory. Run the ‘lspci’ command on the console and verify that the PFs are detected as shown below.
