ARK Poll Mode Driver
====================
Ingress RX and Egress TX operation is by the nominal DPDK API .
The driver supports single-port, multi-queue for both RX and TX.
-Refer to ``ark_ethdev.h`` for the list of supported methods to
-act upon RX and TX Queues.
-
Configuration Information
-------------------------
Usage Example
-------------
-This section demonstrates how to launch **testpmd** with Atomic Rules ARK
-devices managed by librte_pmd_ark.
-
-#. Load the kernel modules:
-
- .. code-block:: console
-
- modprobe uio
- insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
-
- .. note::
-
- The ARK PMD driver depends upon the igb_uio user space I/O kernel module
-
-#. Mount and request huge pages:
-
- .. code-block:: console
-
- mount -t hugetlbfs nodev /mnt/huge
- echo 256 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
-
-#. Bind UIO driver to ARK device at 0000:01:00.0 (using dpdk-devbind.py):
-
- .. code-block:: console
-
- ./usertools/dpdk-devbind.py --bind=igb_uio 0000:01:00.0
-
- .. note::
-
- The last argument to dpdk-devbind.py is the 4-tuple that indentifies a specific PCIe
- device. You can use lspci -d 1d6c: to indentify all Atomic Rules devices in the system,
- and thus determine the correct 4-tuple argument to dpdk-devbind.py
-
-#. 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
-
- [...]
