Qdma xilinx.
Some additional points to consider. 1. With MDMA_PFCH_CACHE_DEPTH=16, less than 15 active queues work flawlessly. 2. When more than 15 queues are “activated” (at the same time or at random times) C2H CMPT interface breaks. Activated here simple means C2H received at least one packet with that QID. 3.
HW also provides ability to interrupt the driver for an incoming mailbox message to a PCIe function. For further details on the mailbox internals and mailbox registers, refer to QDMA_Product_Guide. Physical function (PF) is privileged with full access to QDMA registers and resources, but VFs updates only data handling registers and …For support of Versal QDMA PL-PCIE4 as Root Complex, refer the procedure listed in AR76665; For support of Versal CPM 2021.1 designs as Root Complex, refer the steps listed in AR76664; Change Log 2021.1.
