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 documentation related to throughput ... The IP only has options for link speed of 2.5GT/s or 5.0GT/s (Gen1/Gen2). When I change my part to a -2 speed grade, the 8.0GT/s and 16GT/s link speeds then become available. However, the XDMA (DMA/Bridge Subsystem for PCI Express) and the PCIE block (Versal ACAP Integrated Block for PCI Express) both allow for up to 16GT/s Gen4 speeds even ...QDMA USER INTERRUPT. Hello, we are using QDMA IP version 3 (rev.3) with Vivado 2019.2. We noticed that a port called "user interrupt" is available and that it could be used to generate user interrupts.
