This section demonstrates how to launch **testpmd** with Amazon ENA
devices managed by librte_pmd_ena.
Follow instructions available in the document
:ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>` to launch
**testpmd** with Amazon ENA devices managed by librte_pmd_ena.
#. Load the kernel modules:
Example output:
.. code-block:: console
.. code-block:: console
modprobe uio
insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
.. note::
Currently Amazon ENA PMD driver depends on igb_uio user space I/O kernel module
#. Mount and request huge pages:
.. code-block:: console
mount -t hugetlbfs nodev /mnt/hugepages
echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
#. Bind UIO driver to ENA device (using provided by DPDK binding tool):
.. code-block:: console
./usertools/dpdk-devbind.py --bind=igb_uio 0000:02:00.1
#. Start testpmd with basic parameters:
.. code-block:: console
./x86_64-native-linuxapp-gcc/app/testpmd -l 0-3 -n 4 -- -i
Example output:
.. code-block:: console
