Sample Application Notes

~~~~~~~~~~~~~~~~~~~~~~~~

|

This section demonstrates how to launch ``testpmd`` with QLogic 578xx
|
||||
devices managed by ``librte_pmd_bnx2x`` in Linux operating system.
|
||||
|
||||
#. Request huge pages:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages/nr_hugepages
|
||||
|
||||
#. Load ``igb_uio`` or ``vfio-pci`` driver:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
|
||||
|
||||
or
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
modprobe vfio-pci
|
||||
|
||||
#. Bind the QLogic adapters to ``igb_uio`` or ``vfio-pci`` loaded in the
|
||||
previous step::
|
||||
|
||||
./usertools/dpdk-devbind.py --bind igb_uio 0000:84:00.0 0000:84:00.1
|
||||
|
||||
or
|
||||
|
||||
Setup VFIO permissions for regular users and then bind to ``vfio-pci``:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
sudo chmod a+x /dev/vfio
|
||||
|
||||
sudo chmod 0666 /dev/vfio/*
|
||||
|
||||
./usertools/dpdk-devbind.py --bind vfio-pci 0000:84:00.0 0000:84:00.1
|
||||
|
||||
#. Start ``testpmd`` with basic parameters:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
./x86_64-native-linuxapp-gcc/app/testpmd -l 0-3 -n 4 -- -i
