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 ... 2. Allocate the Queues to a function¶. QDMA IP supports maximum of 2048 queues. By default, all functions have 0 queues assigned. qmax configuration parameter enables the user to update the number of queues for a PF.

Unfortunately, we just found out that not all ultrascale+ devices with PCIe blocks can support QDMA. This seems to be the case with the xczu5ev-sfvc784-1-i, as QDMA does not appear in the IP catalog. I even tried swapping the part in the ZCU-106 design to the xczu5ev chip, but this caused a bunch of errors saying that the xczu5ev chip does not ...We found that there is a configuration option called comp_timeout, set to 50ms, which should be the value associated to the PCIe "Completion Timeout" parameter.
