However, the XDMA (DMA/Bridge Subsystem for PCI Express) and the PCIE block (Versal ACAP Integrated Block for PCI Express) both allow for up to 16GT/s Gen4 speeds even ... Each function implements one 128B inbox and 128B outbox message buffer. These mailboxes are accessible to the driver via PCIe BAR of its own function. HW also provides ability to interrupt the driver for an incoming mailbox message to a PCIe function.

The XDMA/QDMA Simulation IP core is a SystemC-based abstract simulation model for XDMA/QDMA and enables the emulation of Xilinx Runtime (XRT) to device communication. With thisIP a Xilinx Runtime host application (through OpenCL™ APIs) can communicate with kernels,memories, and streaming resources, but the communication is at the transaction ... The patch resolves the issue for us. Once applied, the "impossible" timeouts are no longer seen. I'm not working on this code any more, but if your current driver doesn't have this or an equivalent change then I would expect it to show the same problem at least sometimes, with a greater chance of problems in multithreaded programs.AMD LogiCORE™ QDMA for PCI Express® (PCIe) は、PCI Express 統合ブロックで使用するための高性能で設定可能な Scatter Gather DMA を実装します。. この IP は、オプションで AXI4-MM または AXI4-Stream ユーザー インターフェイスを提供します。.

It includes the Xilinx QDMA IP and RTL logic that bridges the QDMA IP interface and the 250MHz user logic box. The interfaces between QDMA subsystem and the 250MHz box use a variant of the AXI4-stream protocol. Let us refer the variant as the 250MHz AXI4-stream. U45N has two QDMA subsystems.The Xilinx PCI Express Multi Queue DMA (QDMA) IP provides high-performance direct memory access (DMA) via PCI Express. Xilinx provides a DPDK poll mode driver based on DPDK v18.11 that runs on a PCI Express root port host PC to interact with the QDMA endpoint IP via PCI Express.I correctly built the QDMA drivers, and they are able to detect my endpoint pci bus at 0005:01 with the name "qdma01000". The qdma.conf file is filled, and I set the maximum number of queue in qmax file. I am also able to create a memory map queue and see it as /dev/qdma01000-MM-0. I have been using Xilinx github for my steps : https://xilinx ...Xilinx QDMA Subsystem for PCIe example design is implemented on a Xilinx FPGA, which is connected to an X86 host system through PCI Express. Xilinx QDMA Linux Driver package consists of user space applications and kernel driver components to control and configure the QDMA subsystem.Chemical elements are mapped out in the periodic table. Visit HQDMA driver programs the descriptors with buffer base a In particular, register QDMA_C2H_BUF_SZ[0:15] is a 16-bit field. Can we use the full 16-bit, i.e. the maximum buffer size of 65536 bytes. However, in the Xilinx example device driver code, it has a maximum limit of 0x7000. dmaxfer.c: #define QDMA_ST_MAX_PKT_SIZE 0x7000. Therefore, is there a document that defines the above maximum value.

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 Ethernet Platform. The QEP design adds Ethernet support to QDMA based streaming platform. The Ethernet Subsystem is added to the static region of the shell. The platform has three physical functions, two physical functions for device management (PF0) and compute acceleration (PF1), and one physical function (PF2) for Network acceleration.With the current version of Vivado (2023.1), we cannot select PCIe Gen3 or 4 in the QDMA 5.0 block (Soft-IP on the PL). There are no entries in the selection, and the block automation flow throws an error: ERROR: [IP_Flow 19-3461] Value '8.0_GT/s' is out of the range for parameter 'Pl Link Cap Max Link Speed … QDMA: Up to 2K Queues (All can be assigned to on PF or distributed amongst all 4) (Shared DMA Engines) SR-IOV: XDMA: Not supported.
