We don't have a Xilinx solution for measuring latency.
You could use XRT API calls to measure latency from host->pcie->dma->ddr ack (bvalid)
clEnqueueMigrateMemObjects(handle.commands, 1, …, writeEvent)
… followed by …
Since there is no standard solution, each solution will need to be tailored to meet the needs of the application. Is there any other information you can provide?
