Hi, I needed the Resource utilization and performance number for XDMA and QDMA on Zynq Ultrascale\+ board. Thanks, Akshay MQDMA 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 ...

UG1238 (v2019.1) - SDAccel Development Environment states that the U200 supports both "xilinx_u200_qdma_201830_1" and "xilinx_u200_qdma_201910_1" shells ...We used the QDMA driver on github, released for 2019.1 (That said, we also tried it with a few of our patches and found the same issues). 3. We operate teh QDMA in MM mode (well ST interfaces are also available, but we aren't using them). 4. We start a few queues. 4 queues seems to be enough to cause the bug to happen. 4.

This page contains resource utilization data for several configurations of this IP core. The data is separated into a table per device family. In each table, each row describes a test case. The columns are divided into test parameters and results. The test parameters include the part information and the core-specific configuration parameters.
