The DPDK API does not distinguish between physical and IO virtual addresses, and always refers to either as IOVA, even if no IO memory management unit (IOMMU) is involved to provide the VA part. However, DPDK does distinguish between cases where physical addresses are used as IOVA, and cases...
Encountering the following Kernel Panic when running a containerized DPDK application. The application sends and receives packets over VFs created on a 10G NIC (very low traffic rate). Raw [ 1806.630592] vfio-pci 0000:86:02.0: enabling device (0000 -> 0002) [ 1808.060706] i40e 0000:86:00.0...
在共享内存传输的TransportDescriptor中,除了在TransportDescriptorInterface中定义的数据成员外,还定义了以下成员: 数据成员详细说明 特别说明 rtps_dumpfile: 如果该字段不为空,则所有通过DomainParticipant发送和接收的共享内存流量会被追踪到一个文件中。输出文件格式为tcpdump十六进制文本,可以使用协议分析应用程序(如Wire...

Some improvements in DPDK performance (version 1.7 over version 1.6) are attributable in part to newer processor chips assigning a bigger portion of L1–L2 cache to I/O (and DDIO allows the NIC to write buffer descriptors to that cache24). This creates a high degree of cache locality and ...
