Hi, I apologise in advance for the length of this post... (We currently are developing on version 20.1 of the driver.) We have extended the QDMA driver with network capabilities (similar to as is done in the QEP driver). Since the H2C and C2H interrupts are by default serviced on the same interrupt vector, this means that the TX and RX cannot run …

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.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.Looking for something to do tonight?
