Subject: [dpdk-users] Invalid NUMA socket when running helloworld on VM linux
Date: Sat, 2 Mar 2019 14:51:58 -0800 (PST)	[thread overview]
Message-ID: <fce56772-28bd-4672-8dad-1289f8462c2e@default> (raw)

 

Hi Gurus,

 

I launched a virtual box based linux on my windows, and my PC is thinkpad T480. 

After configured the huge pages as number of 2MBs and the cpu number as 4 on the vm linux, I build DPDK and run the example of hellowworld but get the below output, in which I saw the "invalid NUMA socket". What does it mean and does it matter, as I see the hello from core # is also printed.

 

[~ build]$ sudo ./helloworld 

EAL: Detected 4 lcore(s)

EAL: Detected 1 NUMA nodes

EAL: Multi-process socket /var/run/dpdk/rte/mp_socket

EAL: Probing VFIO support...

EAL: PCI device 0000:00:03.0 on NUMA socket -1

EAL:   Invalid NUMA socket, default to 0

EAL:   probe driver: 8086:100e net_e1000_em

hello from core 1

hello from core 2

hello from core 3

hello from core 0
