在Kubernetes中,rte_eth_dev_configure是用来配置DPDK设备的函数。DPDK(Data Plane Development Kit)是一种用于加速数据包处理的框架,它为高性能网络应用程序提供了底层硬件的访问。 ## 2. rte_eth_dev_configure的作用 rte_eth_dev_configure函数用于配置DPDK设备的端口,包括设置端口的速率、双工模式、MAC地址等。它...

rte_eth_devices rte_eth_devices写入数据位置 main函数启动之后,会调用rte_eal_init,在rte_eal_init中跟ether dev相关的是rte_bus_scan和rte_bus_probe。 1 rte_bus_scan 初步扫描总线,函数如下,对rte_bus_list链表,迭代scan各总线。 1.1 rte_bus_scan...
于是将该机器的DPDK版本也换为20.11.7,再编译DPDK,问题解决。 结论 我后来又在另一台机器上也出现了类似的问题:在rte_eth_dev_start()报错,但最终停在的位置不是libibverbs.so.1,而是libmlx5.so。也是用了同样的方法解决。 最终还是不知道是什么原因导致了这个问题。以后乖乖用20.11.7就好了。
