Subject: [dpdk-dev] [PATCH v2 07/10] doc: refer PMD compile and test section from liquidio doc
Date: Wed, 12 Apr 2017 00:26:47 +0530 [thread overview]
Message-ID: <1491937010-16553-8-git-send-email-shijith.thotton@caviumnetworks.com> (raw)
In-Reply-To: <1491937010-16553-1-git-send-email-shijith.thotton@caviumnetworks.com>
Refer the section which explains driver compilation and running of
testpmd in Linux, instead of describing it in driver documentation.

-Driver Compilation
-------------------
-
-To compile LiquidIO PMD for Linux x86_64 gcc target, run the following "make"
-command:
-
-.. code-block:: console
-
- cd <DPDK-source-directory>
- make install T=x86_64-native-linuxapp-gcc

-Sample Application Notes
-------------------------
-
-This section demonstrates how to launch ``testpmd`` with LiquidIO® CN23XX
-device managed by ``librte_pmd_lio`` in Linux operating system.
-
-#. Mount huge pages:
-
- .. code-block:: console
-
- mkdir /mnt/huge
- mount -t hugetlbfs nodev /mnt/huge
-
-#. Request huge pages:
-
- .. code-block:: console
-
- echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages/nr_hugepages
-
-#. Load ``vfio-pci`` driver:
-
- .. code-block:: console
-
- modprobe vfio-pci
-
-#. Bind the LiquidIO VFs to ``vfio-pci`` loaded in previous step:
-
- 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 0000:03:00.3 0000:03:08.3
-
-#. Start ``testpmd`` with basic parameters:
-
- .. code-block:: console
-
- ./build/app/testpmd -c 0xf -n 4 -- -i
-
- Example output:
-
- .. code-block:: console
