Hello everyone, I'm using QDMA v42 with one activated PF only, and I would like to increase the number of MSIX vectors for this PF to more than 32. Did you figure out how these "tm_dsc" signls work, we are using the qdma with dpdk driver now, at the beginning we use only the "s_axis_c2h_tready" signal as backpressure control, but when in speed test, it seemed that the signal does not have related to each queue, for example, when in 100Gbps flow test with 8 queue, part of the queue is underflow while others overflow. 2、About the size of BRAM, i think it should has something to do with you dpdk queues, you should need one bram with each queue, because you need to count each queue's descriptors to decide whether it has ability to accept user' data. 303268] qdma: probe_one: 0000: 01: 00. How to get the "desktop files" or icon working of the Xilinx 2020. The QDMA shell includes a high-performance DMA that uses multiple queues optimized for both high bandwidth and high.

Unfortunately I was not able to find any document on the real achievable throughput of the XDMA IP in DMA/Bridge mode. Dynamic queue configuration, refer to Interface file, qdma_exports. I can't see any good tutorials which show how to develop such code. Thank you for pointing that out 硬件配置：KU11P，QDMA 3. vh file runs in the simulation. The platform has three physical functions, two physical functions for device management (PF0) and compute acceleration (PF1), and one. The problem is that QDMA does not transfer data to the host after receiving a specific number of requests. 'dmesg' shows the system created only 7 queues for my NVMe device though the NVMeTC has 64 queues Hi all, anyone on this? Is there a patch to fix this issue? Is it possible that the QDMA 3.
