dpdk 接口初始化在 dpdk_lib_init 函数中完成,主要步骤包括初始化 dpdk_device_t 结构体,调用 ethernet_register_interface 注册接口,配置网卡参数,并为接口分配收包线程。dpdk 收包通过 input node dpdk_input_node 实现,dpdk_device_input 函数完成实际的收包操作,通常将报文传递给下一个 node,...

Use Intel® VTune™ Profiler to analyze the efficiency of DPDK Event Device pipeline utilization in your DPDK-based application and identify issues, such as inhomogeneous load distribution and worker core underutilization.
绑定网卡选择23 Bind Ethernet device to IGB UIO module输入网卡前面的数字序号,即可绑定该网卡,这里我们有两个需要绑定,eth1和eth2,它们的序号分别是0000:02:06.0和0000:02:07.0绑定完再次查看网卡状态,我们可以看见两个网卡都已经是用于dpdk了:13. 到这一步dpdk的配置都已经结 9、束了,下面可以运行一下dpdk...

--use-device: 仅使用指定的以太网设备。使用逗号分隔 [domain:]bus:devid.func 值,不能与 -b 选项一起使用。 --socket-mem: 从特定插槽上的hugepage分配内存。 -m MB: 内存从hugepage分配,不管处理器插槽。建议使用 --socket-mem 而非这个选项。
