在main函数的一开始,调用rte_eal_init()获取用户、系统的相关配置信息以及设置基础运行环境,其中包括调用rte_eal_pci_init()来扫描、获取系统中的CPI网卡信息; 首先,初始化pci_device_list链表,后面扫描的到的pci网卡设备信息会记录到这个链表中; 然后,调用rte_eal_pci_scan()扫描系统中的PCI网卡:遍历”/sys/bus...

针对你提出的问题“eal: cannot create lock on '/var/run/dpdk/rte/config'. is another primary process running?”,我们可以按照以下步骤进行分析和解决: 检查'/var/run/dpdk/rte/config'文件的锁状态: 使用lsof或fuser命令来检查是否有其他进程正在使用或锁定该文件。 使用lsof命令: bash sudo lsof /var/ru...

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/* Scan all the buses for registered devices */ in rte_eth_devices ci 迭代 数据 转载 数据探索...
