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.

mempool <mbuf_pool>@0x13fed3e00

  flags=10

  socket_id=0

  pool=0x1140300000

  iova=0x13fed3e00

  nb_mem_chunks=1

  size=65535

  populated_size=65535

  header_size=128

  elt_size=10200

  trailer_size=40

  total_obj_size=10368

  private_data_size=128

  ops_index=0

  ops_name: <cn9k_mempool_ops>

  avg bytes/object=10368.558602

mempool <node_pool>@0x1575d8180

  flags=10

  socket_id=-1

  pool=0x19ffffd00

  iova=0x1575d8180

  nb_mem_chunks=2

  size=134217727

  populated_size=134217727

  header_size=128

  elt_size=256

  trailer_size=0

  total_obj_size=384

  private_data_size=0

  avg bytes/object=384.000094

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.

Heap id:0

        Heap name:socket_0

        Free_size:2403644544,

        Greatest_free_size:536870016,

        Alloc_count:293,

        Free_count:5,
