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.

We used the QDMA driver on github, released for 2019.1 (That said, we also tried it with a few of our patches and found the same issues). 3. We operate teh QDMA in MM mode (well ST interfaces are also available, but we aren't using them). 4. We start a few queues. 4 queues seems to be enough to cause the bug to happen. 4. 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. Not able to cross compile QDMA IP Driver for arm64.
