在1028上DPDK怎么使用

shocking

请教下在1028板子上怎么测试OK1028A-C平台的DPDK环境
有具体的配置步骤吗？

1.想把eno0 swp0 swp1 swp2 swp3全部配置成DPDK的转发端口 该怎么配置转发都走DPDK？设备树里面        
port@5 {
                status = "okay";
                /delete-property/ managed;
                /delete-property/ phy-handle;

                fixed-link {
                        speed = <1000>;
                        full-duplex;
                };
        };
};

&enetc_port3 {
        status = "okay";
};

dpdk-devbind -s

Network devices using DPDK-compatible driver
============================================
0000:00:00.0 'Device e100' drv=vfio-pci unused=uio_pci_generic
0000:00:00.6 'Device e100' drv=vfio-pci unused=uio_pci_generic

Network devices using kernel driver
===================================
0000:00:00.2 'Device e100' if=eno2 drv=fsl_enetc unused=vfio-pci,uio_pci_generic
0000:00:00.5 'Device eef0' if=swp2,swp0,swp5,swp3,swp1 drv=mscc_felix unused=vfio-pci,uio_pci_generic

Other Network devices
=====================
0000:00:00.1 'Device e100' unused=vfio-pci,uio_pci_generic

2.增加的swp5是干什么用的？
3.我用dpdk-devbind -s查看网口驱动，意思swp2,swp0,swp5,swp3,swp1是绑定在一个物理设备上的？如果要使用这4个网口走DPDK转发改怎么绑定网口呢？
4.lspci: Unable to load libkmod resources: error -12这报的错是什么原因？


5.l2fwd -c 0x3 -n 1 -- -p 0x3 -q 1 --no-mac-updating  这样能跑起来，-p 0x3是指使用port0和port1，这port0 port1指的是哪2个网卡？我如果要使用swp0,swp1,swp2,swp3是不是改成-p 0xf就行？但是这样会报错,log如下:

6.我在板子上运行 l2fwd -c 0x3 -n 1 -- -p 0x3 -q 1 --no-mac-updating，eno0和swp0上分别接了2台windows PC配置了同一网段IP地址，互ping也不通抓不到包，l2fwd统计里面也没有包增加，是什么原因？

1.您是在什么位置看到的DPDK需要添加SWP5节点的？

   2.目前我们这边测试只是关于手册中的测试，并没有说添加SWP5节点。

   3.关于绑定swp网口的问题，您可以参考一下原厂的LSDK手册里面的介绍，应该可以解答您的问题。

   路径：原厂资料/LSDKUG_Rev20.04.pdf

   4.报错信息的问题我这边帮您找了个相关的报错解决办法，希望可以帮助到您。

   参考链接：lspci: Unable to load libkmod resources: error -12 怎么解决 - 我爱学习网 (5axxw.com)

   5.运行命令报错，这个和您的命令参数配置有关系，您着重看一下-C使用核数，-n内存通道数，还有-p使用的port几。
