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.QDMA supports three types of C2H stream modes: simple bypass, cache bypass, and cache internal. Currently, I am working on the cache bypass mode with prefetch to send data from the card to the host. The problem is that QDMA does not transfer data to the host after receiving a specific number of requests. It seems that the problem originates ...76647 - Versal Adaptive SoC (Vivado 2021.1 - 2023.1) - PL-PCIE4 QDMA Bridge Mode Root Port Linux Driver Support. ... 65444 - Xilinx PCI Express DMA Drivers and Software Guide; Vivado ML Edition 2023.x - Known Issues; Was this article helpful?

Hi all, What is the minimum latency for a 300-byte packet, for instance, using the QDMA subsystem for PCIe, from host to FPGA (VU9P)? There only seem to be measurements and …I am attempting to configure a QDMA IP block for Tandem PROM configuration, but there is either a bug in the customization interface or it is not yet supported for my device (XCKU15P). I have previously configured an XDMA IP block for Tandem PROM configuration of this same device, and it works in hardware. When I attempt to configure … QDMA Ethernet Platform. The QEP design adds Ethernet support to QDMA based streaming platform. The Ethernet Subsystem is added to the static region of the shell. The platform has three physical functions, two physical functions for device management (PF0) and compute acceleration (PF1), and one physical function (PF2) for Network acceleration. QDMA_C2H_CMPT_COAL_BUF_DEPTH == 00000020. CMPT is the completion context structure. I am using completion entry size of 32B. xivar (Member) 4 years ago. Another observation. If I add a delay between packets at the input stream - usleep (100) - all seems to work well. 1、The latency is not a key parameter to us, and we had not tried the linux driver, so i can not talk about this issue. 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.There are plenty of artictes on the transfer performance of the XDMA IP in DMA mode and or QDMA IPs. Unfortunately I was not able to find any document on the real achievable throughput of the XDMA IP in DMA/Bridge mode. I wanted to ceate a custom DMA on AXI4 specification and for that purpose, using the XDMA in Bridge mode seemed like a good …Hi, I needed the Resource utilization and performance number for XDMA and QDMA on Zynq Ultrascale\+ board.

QDMA Linux Driver … 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. In particular, register QDMA_C2H_BUF_SZ[AXI4-Lite. AXI-Stream. AXI4-MM.
