To clarify, the log message when my application called rte_mempool_create() to
create the "node_pool", and the call succeeded.

Hi,
I have recently started using DPDK. I am working on a project on OcteonTX2 with
DPDK 11.23.01. I am seeing this message from EAL during EAL init, but
everything is working.
EAL: eal_memalloc_alloc_seg_bulk(): couldn't find suitable memseg_list
The system has 96GB of memory. These 2 pools get created and everything works
fine.

You read that right. I’ve got 128*1024*1024 256 byte buffers created for data.
I also see there is still heap left, although pretty low after.

Is there anything wrong with that EAL log? Is there a lurking problem?
Thanks,Don Trotter
