The PCIe QDMA can be implemented in UltraScale+ devices. Both the linux kernel driver and the DPDK driver can be run on a PCI Express root port host PC to interact with the QDMA endpoint IP via PCI Express.

We recommend qdma for lower latency, we recommend the ethernet ports for consistent latency as there is high overhead for PCIe. It doesn't look like there is a QDMA shell coming for the U280, you should contact your xilinx marketing or sales rep to see if there are any Ethernet enabled shells.Following today’s news that Lenovo and Alphabet-owned Waymo are sitting out the in-person element of CES 2022, Intel just announced that it’s moving to “minimize” its presence at t...

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. We would like to understand how to correctly interface custom logic with that port and what we should do at driver level (probably in libqdma ...

mmilos (Member) asked a question. October 1, 2020 at 1:18 PM. QDMA v4.0 stream card to host transfers not working. Upon upgrading project from QDMA version 3.0 to version 4.0 i noticed that c2h transfers are no longer working. After further inspection i noticed that s_axis_c2h_cmpt_tready pin is always low which prevents me from sending any data.**BEST SOLUTION** Hi, This should be 16 or 32. We will update the document in the next revision. Thank you for pointing that out. Thanks. 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.
