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  ops_index=3  ops_name: <ring_mp_mc>  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        Heap_size:55834574848,        Free_size:2403644544,        Alloc_size:53430930304,        Greatest_free_size:536870016,        Alloc_count:293,        Free_count:5,
Linux free stats.

Is there anything wrong with that EAL log? Is there a lurking problem?
