DPDK 运行 testpmd 失败。 EAL:no 探测到以太网设备
DPDK run testpmd failed. EAL:no probed ethernet device
我是 dpdk 的新手,在 docker 上使用 dpdk-stable-17.11.2。
OS 是 Ubuntu 14.04,内核是 3.19.0-80-generic。
我按照下面的 dpdk-setup.sh 将 igb_uio 驱动程序绑定到我的设备。
[14] x86_64-native-linuxapp-gcc
[17] Insert IGB UIO module
[18] Insert VFIO module
[19] Insert KNI module
[20] Setup hugepage mappings for non-NUMA systems
[21] Setup hugepage mappings for NUMA systems
[22] Display current Ethernet/Crypto device settings
[23] Bind Ethernet/Crypto device to IGB UIO module
[24] Bind Ethernet/Crypto device to VFIO module
[25] Setup VFIO permissions

BCM57810似乎不受当前版本的Broadcom PMD支持:

作为解决方法,您可以尝试使用受支持的 NIC(如果可能)或虚拟设备(可能要慢得多)。

您没有列出您的命令行选项,但您绝对应该检查它的 lcore 掩码或核心列表或核心映射。以下是 EAL 命令行选项列表:
