* Prepare physical memory mapping: fill configuration structure with * these infos, return 0 on success. * 1. map N huge pages in separate files in hugetlbfs * 2. find associated physical addr * 3. find associated NUMA socket ID * 4. sort all huge pages by physical address * 5. remap...
编译过程 执行Step 1 首先下载dpdk19.08.2,解压,进入解压目录 cd./dpdk-stable-19.08.2 使用dpdk提供的工具编译 ./usertools/dpdk-setup.sh 输入36 ,回车 报错一 eal/eal_memory.c:32:10: fatal error: numa.h: No such file or directory 报错原因是numa没下载。 解决方式 下载缺失部分 sudoapt-get inst...
FPM: Function Private Memory, 函数私有内存 PBLE: Physical Buffer List Entry 物理缓冲区列表条目 HNS: Hisilicon Network Subsystem, 海思网络子系统 简介 DPDK使用hugetlbfs内核文件系统支持大页的分配。连续的内存段抽象为rte_memseg,如果把rte_memseg中的一部分命名并以供使用,那么称为rte_memzone 在每个进程目...
34.1.1 Memory Copy: Do not Use libc in the Data Plane 内存拷贝:不要再数据面使用lic libc中的很多函数不是为性能设计的。例如 memcpy() 或 strcpy() 不应该被用在 data plane。若是拷贝小结构,性能是个简单的技术,可以被编译器优化。请参阅《VTune ™性能优化要点》来自Interl新闻的建议。
memory: 1000Mi hugepages-1Gi: 12Gi The hugepages allocation is user and application dependent, and must match the amount pre-allocated by the Performance Profile. Refer to theonline documentationfor more details. Scheduling priority In general, a task may need to be run ahead of all theSCHED...

DPDK mbuf is a data structure used in the DPDK (Data Plane Development Kit) to manage network packets efficiently. It represents a single network packet in memory and contains information about its metadata, such as the length of the packet, its destination and source MAC addresses, etc. ...
