Drivers and the corresponding documentation are available at DMA IP Drivers.

Note: Starting from 2022.1 release of the Linux driver for QDMA, if a design is using streaming queues, they must be explicitly enabled through API as they are not configured at module load. If a design is using tandem PCIe methodology at power-on, the enablement must occur after Stage 2 is loaded to the device.
Important: 8 MSI-X vectors are needed on all functions (PF/VF) for using QDMA IP driver.
