[dpdk-dev] testpmd errors

Hi All,

    I am trying to install dpdk. Since it says to run test and testpmd to
see if everything works, I ran those apps.

    So far test works fine for me. However when I run testpmd, I get the
following:

    *probe driver: 8086:10c8 rte_ixgbe_pmd
*
*    unbind kernel driver /sys/bus/pci/devices/0000:04:00.0/driver/unbind
*
*    bind PCI device 0000:04:00.0 to igb_uio driver
*
*    Device bound
*
*    map PCI resource for device 0000:04:00.0
*
*    PCI memory mapped at 0x7f0e680e6000
*
*    rte_memzone_reserve_aligned(): No appropriate segment found
*
*    pci_uio_map_resource(): cannot store uio mmap details
*
*    Error - exiting with code: 1
*
*    No probed ethernet devices - check that CONFIG_RTE_LIBRTE_IGB_PMD =y
and that CONFIG_RTE_LIBRTE_IXGBE_PMD=y in your configuration file *

     Below is what I see in dmesg:

     *igb_uio 0000:04:00.0: irq 79 for MSI/MSI-X
*
*     uio device registered with irq 4f

*
*     *My setup is a dell R510 with two quad-core Xeons (E5506), 32 GB
memory. It has 5 NICs of which two are up (eth0: BCM5716 and eth4 Intel
82598EB 10 Gigabit). Both NICs are on the same subnet before I had dpdk
attach to eth4 by running the following command:

     *sudo ./testpmd -c ff -n 4 -r 2 -m 2048 -b 0000:01:00.0*

     0000:04:00.0 is the Intel and 0000:01:00.0 is the Broadcom.

     Originally I was getting the "No probed ethernet devices" because I
had a non-supported NIC, however 82598 is a supported NIC and it seems that
dpdk did bind to the Intel NIC. However, rte_eth_dev_count() somehow still
returns 0. Any help would be great! Thanks!

Just a bit more of information, I am using ubuntu 12.04 server.

Hi, it seems the above error is due to the fact I don't have NUMA enabled
even though half of my cores use socket 0 and half of my cores use socket
1. For some reason all the hugepage allocations are on socket 0 (it makes
sense as I don't have NUMA enabled). Also I am unable to use:

   sudo ./testpmd -c ff -n 4 -r 2 --socket-mem=1024,1024 command to
allocate memory to socket 1 as it is not part of dpdk usage which is weird
(do I have to have NUMA enabled to use this feature?)

I have two Intel quad-core Xeon 5506. I am not sure how to enable NUMA on
them or if these Intel chips even support them. Does anyone know?

Peter
