Hi, I'm new to DPDK.
I have gone through the user guide, set up environment, hugepages. I can get the helloworld app work. Now, when I tried to play with the testpmd app, I got the following issue: [root at localhost dpdk-1.8.0]# build/app/testpmd -c 0x2 -n1 -- -i --nb-cores=1 --nb-ports=0x1 ..... EAL: TSC frequency is ~2594110 KHz EAL: Master core 1 is ready (tid=e07b3840) PMD: ENICPMD trace: rte_enic_pmd_init EAL: PCI device 0000:02:00.0 on NUMA socket -1 EAL: probe driver: 8086:10d3 rte_em_pmd EAL: 0000:02:00.0 not managed by UIO driver, skipping EAL: PCI device 0000:03:00.0 on NUMA socket -1 EAL: probe driver: 8086:10d3 rte_em_pmd EAL: PCI memory mapped at 0x7f06df800000 EAL: PCI memory mapped at 0x7f06df820000 PMD: eth_em_dev_init(): port_id 0 vendorID=0x8086 deviceID=0x10d3 EAL: PCI device 0000:04:00.0 on NUMA socket -1 EAL: probe driver: 8086:10d3 rte_em_pmd EAL: 0000:04:00.0 not managed by UIO driver, skipping EAL: PCI device 0000:05:00.0 on NUMA socket -1 EAL: probe driver: 8086:10d3 rte_em_pmd EAL: 0000:05:00.0 not managed by UIO driver, skipping*PANIC in main(): Empty set of forwarding logical cores - check the core mask supplied in the command parameters* 5: [build/app/testpmd() [0x428ea5]] 4: [/lib64/libc.so.6(__libc_start_main+0xf5) [0x7f06df8e2af5]] ..... It says the core mask is not right. I set it to 0x2 because my CPU only has 2 cores. I don't quite get it. Can someone help me with this? And has anyone else encountered the same issue? Thanks!
