Proper linux driver version for QDMA v3.0 under vivado 18.3

Good morning

We are implementing a simple system using QDMA Version 3.0, patched with Tactical patch 72013 as per AR# 72013.

We are looking the proper version of Linux software drivers

currently we downloaded the drivers from github "dma_ip_drivers"  but  we have an unexpected behaviour: the board is recognized by the O.S,
but the "qdma_pf" driver (correctly installed in linux) is not loaded and "linked" to the IP.
In fact, the text "Kernel Driver in use: qdma_pf" dies not appear.

This is the report ip status related to the QDMA

This is the block diagram, very simple (QDMA, two memory controller and related memories)

This is the capabilities page of IP customization

Hi @marco_pavesi_mindway ,

The driver from git-hub is the proper driver version.

Can you run the install process from the driver source directory the way you did before? Let us know if the driver gets linked.
