Some additional points to consider. 1. 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.Paper Versus Plastic: Environmental Disadvantages of Each - Paper versus plastic is a hot topic when choosing between plastic bags and paper bags.

QDMA Linux Driver … QDMA driver comes with a command-line configuration utility called “dma-ctl” to manage the driver. The Xilinx QDMA control tool, dma-ctl is a Command Line utility built along with driver and allows administration of the Xilinx QDMA queues. It can perform the following functions. Query the QDMA functions/devices the driver has bound into QDMA driver programs the descriptors with buffer base address and length to be transmitted. QDMA driver updates the H2C ring PIDX and polls the status descriptor for CIDX to be same as PIDX. Upon H2C ring PIDX update, DMA engine fetches the descriptors and passes them to H2C MM Engine for processing.

Once the installation is done, the QDMA devices are visible in Device Manager under Xilinx Drivers -> Xilinx PCIe Multi-Queue DMA. Do the above steps for all QDMA devices available in Device Manager.
