QDMA supports three types of C2H stream modes: simple bypass, cache bypass, and cache internal. Currently, I am working on the cache bypass mode with prefetch to send data from the card to the host. The problem is that QDMA does not transfer data to the host after receiving a specific number of requests. It seems that the problem originates ...

The QDMA shell includes a high-performance DMA that uses multiple queues optimized for both high bandwidth and high packet count data transfers. The QDMA shell provides. * Streaming directly to continuously running kernels * High bandwidth and low latency transfers * Kernel support for both AXI4-Stream and AXI4 Memory Mapped.

Feb 16, 2022 · When debugging user designs that use Xilinx PCI Express Drivers such as QDMA and XDMA, it is helpful to add debug print commands at different parts of the driver source to identify where the unexpected behavior occurs. This helps users to further narrow down the issue, or in most cases the root cause and solution for the issue. 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. [602496.969350] qdma_vf: qdma_mod_init: Xilinx QDMA VF Reference Driver v2023. 1.0. 0.

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.
