Hi, Recently, I use an V7-330T to develop a function called virtio-net, though it hard, but it works now. The driver needn't be changed and the add-in card would work as an virtio-net device. Now, I am working on SRIOV, what I want is to use SR-IOV techbology to implement 256 functions. and every function could be used for an VM.I correctly built the QDMA drivers, and they are able to detect my endpoint pci bus at 0005:01 with the name "qdma01000". The qdma.conf file is filled, and I set the maximum number of queue in qmax file. I am also able to create a memory map queue and see it as /dev/qdma01000-MM-0.
