DPDK send customized pkt but fail to receive

问题 I'm trying to send customized packages with dpdk, but i find that some package structure will make it fail to receive. For example, i define the package structure like this: union my_pkt{ struct hdr{ uint32_t id; uint32_t name_len; uint64_t tsc; uint8_t name[100]; }__attribute__((__packed__)) pkt_hdr; char buff[500]; }; My server running dpdk can only receive 1st batch of pkts, but the returned value of rte_eth_tx_burst() shows much more packages which have been sent. However , if i modify

前言: 给出DPDK架构的一个全局描述 DPDK的主要目标就是要为数据面快速报文处理应用提供一个简洁但是完整的框架。 用户可以通过代码来理解其中使用的一些技术,并用来构建自己的应用原型或是添加自己的协议栈。 用户也可以替换DPDK提供的原生的选项。 来源: CSDN 作者: cuibin1991 链接: https://blog.csdn.net/cuibin1991/article/details/103610902

DPDK内存(一)存储系统

半腔热情 提交于 2019-12-15 09:08:08
简介 一般而言,存储系统不仅仅指用于存储数据的磁盘、磁带和光盘存储器等,还包括内存和CPU内部的Cache。当处理完毕之后,系统还要提供数据存储的服务。存储系统的性能和系统的处理能力息息相关,如果CPU性能很好,处理速度很快,但是配备的存储系统吞吐率不够或者性能不够好,那CPU也只能处于忙等待,从而导致处理数据的能力下降。 1.系统架构的演进 在当今时代,一个处理器通常包含多个核心(Core),集成Cache 子系统,内存子系统通过内部或外部总线与其通信。 在经典计算机系统中一般都有两个标准化的部分:北桥(North Bridge)和南桥(South Bridge)。它们是处理器和内存以及其他外设沟通的渠道。处理器和内存系统通过前端总线(Front Side Bus,FSB)相连,当处理器需要读取或者写回数据时,就通过前端总线和内存控制器通信。 来源: CSDN 作者: cuibin1991 链接: https://blog.csdn.net/cuibin1991/article/details/103497014

How to run Intel DPDK application in a virtual machine?

守給你的承諾、 提交于 2019-12-13 02:22:46
问题 Anyone managed to run Intel DPDK-based application in a virtual machine? I have an application based on DPDK which I'm trying to bring up inside VirtualBox. Intel mentions paravirtualized network interfaces in its documentation but I could not find any specific instructions related to virtual machine compatibility. The application fails with the following error: EAL: coremask set to 3 EAL: 0 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for that size PANIC in rte_eal_init

问题 I am trying to build a platform using Docker , OVS+DPDK . 1. Set up DPDK + OVS I set up DPDK+OVS using dpdk-2.2.0 with openvswitch-2.5.1 . First, I compile the code of DPDK , set up hugepages. I do NOT bind NIC, because I don't get traffic from outside. Then, I compile the code of openvswitch , set with-dpdk . Start up OVS with the following script: #!/bin/sh sudo rm /var/log/openvswitch/my-ovs-vswitchd.log* export PATH=$PATH:/usr/local/share/openvswitch/scripts export DB_SOCK=/usr/local/var
