i can tell you that with the very same QDMA example design on a Linux machine, i don't have this issue. so the VCK190 programmed with the example design is operational. if you can investigate the crash dump file which points to QDMA.sys being the issue maybe you can say what is the problem. i know that Xilinx does not support the QDMA driver ...Airbnb's first-quarter earnings beat Wall Street's targets, but executives warned of a tougher second quarter.

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. Query control and configuration.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. I have been using Xilinx github for my steps : https://xilinx ...
The examples in this tutorial are created using the Xilinx tools running on a Windows 10, 64-bit operating system, Vitis software platform and PetaLinux on a Linux 64-bit operating system. Other versions of the tools running on other Windows installs might provide varied results.
All getting similar numbers. To keep things brief, I am getting the following performance numbers. As you can see, we are only able to get 5.5GB in the C2H path under what seems to be ideal circumstances (according to QDMA performance AR). This is much smaller than the expected performance that is between 10-14 …This page contains resource utilization data for several configurations of this IP core.

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.
