Re: [dpdk-users] Issue on Running KNI application

Hi Reshma,

I am getting error, upon executing saying that it's an invalid core mask.

Also please let me know how you are calculating the hexadecimal bitmask for the cores.

./kni -c 0x1E -n 4 -- -P -p 0x3 --config="(0,1,3),(1,2,4)"

EAL: Detected lcore 0 as core 0 on socket 0
EAL: Detected lcore 1 as core 1 on socket 0
EAL: Detected lcore 2 as core 2 on socket 0
EAL: Detected lcore 3 as core 3 on socket 0
EAL: Support maximum 128 logical core(s) by configuration.
EAL: Detected 4 lcore(s)
EAL: lcore 4 unavailable
EAL: invalid coremask

Regards,
Arun Raj

Hi Arun,

Core mask value i.e. -c value should be 0x1E in your command. Because you are using cores 1,2,3,4 so their respective bits must be set to 1 in -c value.

./kni -c 0x1E -n 4 -- -P -p 0x3 --config="(0,1,3),(1,2,4)"

Thanks,
Reshma
