[dpdk-users] rte_eal_init fails with --socket-mem set to more than 192MB per socket

[Sarthak Ray]

Hi,

I am using dpdk-2.1.0 and I am not able to reserve memory beyond 192MB per socket by using --socket-mem option. I see below error logs, though my system has enough free memory.

EAL: Not enough memory available on socket 0! Requested: 256MB, available: 192MB
PANIC in rte_eal_init():

Is there any max limit for reserving memory per socket? If yes, then please suggest me how to increase that limit.

Thanks in advance,
