The QEDE poll mode driver library (**librte_pmd_qede**) implements support
for **QLogic FastLinQ QL4xxxx 25G/40G/100G CNA** family of adapters as well
as their virtual functions (VF) in SR-IOV context. It is supported on
several standard Linux distros like RHEL7.x, SLES12.x and Ubuntu.
It is compile-tested under FreeBSD OS.

More information can be found at `QLogic Corporation's Website
<http://www.qlogic.com>`_.

Prerequisites
-------------

- Requires firmware version **8.10.x.** and management firmware
  version **8.10.x or higher**. Firmware may be available
  inbox in certain newer Linux distros under the standard directory
  ``E.g. /lib/firmware/qed/qed_init_values-8.10.9.0.bin``

- If the required firmware files are not available then visit
  `QLogic Driver Download Center <http://driverdownloads.qlogic.com>`_.

Performance note
~~~~~~~~~~~~~~~~

- For better performance, it is recommended to use 4K or higher RX/TX rings.

Config File Options
~~~~~~~~~~~~~~~~~~~

The following options can be modified in the ``.config`` file. Please note that
enabling debugging options may affect system performance.

- ``CONFIG_RTE_LIBRTE_QEDE_PMD`` (default **y**)

  Toggle compilation of QEDE PMD driver.

- ``CONFIG_RTE_LIBRTE_QEDE_DEBUG_INFO`` (default **n**)

  Toggle display of generic debugging messages.

- ``CONFIG_RTE_LIBRTE_QEDE_DEBUG_DRIVER`` (default **n**)

  Toggle display of ecore related messages.

- ``CONFIG_RTE_LIBRTE_QEDE_DEBUG_TX`` (default **n**)

  Toggle display of transmit fast path run-time messages.

- ``CONFIG_RTE_LIBRTE_QEDE_DEBUG_RX`` (default **n**)

  Toggle display of receive fast path run-time messages.

- ``CONFIG_RTE_LIBRTE_QEDE_FW`` (default **""**)

  Gives absolute path of firmware file.
  ``Eg: "/lib/firmware/qed/qed_init_values_zipped-8.10.9.0.bin"``
  Empty string indicates driver will pick up the firmware file
  from the default location.

Driver Compilation
~~~~~~~~~~~~~~~~~~

To compile QEDE PMD for Linux x86_64 gcc target, run the following ``make``
command::

   cd <DPDK-source-directory>
   make config T=x86_64-native-linuxapp-gcc install

To compile QEDE PMD for Linux x86_64 clang target, run the following ``make``
command::

   cd <DPDK-source-directory>
   make config T=x86_64-native-linuxapp-clang install

To compile QEDE PMD for FreeBSD x86_64 clang target, run the following ``gmake``
command::

   cd <DPDK-source-directory>
   gmake config T=x86_64-native-bsdapp-clang install

To compile QEDE PMD for FreeBSD x86_64 gcc target, run the following ``gmake``
command::

   cd <DPDK-source-directory>
   gmake config T=x86_64-native-bsdapp-gcc install -Wl,-rpath=\
                                        /usr/local/lib/gcc49 CC=gcc49


Sample Application Notes
~~~~~~~~~~~~~~~~~~~~~~~~

This section demonstrates how to launch ``testpmd`` with QLogic 4xxxx
devices managed by ``librte_pmd_qede`` 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`` driver:

   .. code-block:: console

      insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko

#. Bind the QLogic 4xxxx adapters to ``igb_uio`` loaded in the
   previous step:

   .. code-block:: console

      ./usertools/dpdk-devbind.py --bind igb_uio 0000:84:00.0 0000:84:00.1 \
                                              0000:84:00.2 0000:84:00.3

#. Start ``testpmd`` with basic parameters:
   (Enable QEDE_DEBUG_INFO=y to view informational messages)

   .. code-block:: console

      testpmd -c 0xff1 -n 4 -- -i --nb-cores=8 --portmask=0xf --rxd=4096 \
      --txd=4096 --txfreet=4068 --enable-rx-cksum --rxq=4 --txq=4 \
      --rss-ip --rss-udp

SR-IOV: Prerequisites and Sample Application Notes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This section provides instructions to configure SR-IOV with Linux OS.

**Note**: librte_pmd_qede will be used to bind to SR-IOV VF device and Linux native kernel driver (QEDE) will function as SR-IOV PF driver. Requires PF driver to be 8.10.x.x or higher.

#. Verify SR-IOV and ARI capability is enabled on the adapter using ``lspci``:

   .. code-block:: console

      lspci -s <slot> -vvv

   Example output:

   .. code-block:: console

      [...]
      Capabilities: [1b8 v1] Alternative Routing-ID Interpretation (ARI)
      [...]
      Capabilities: [1c0 v1] Single Root I/O Virtualization (SR-IOV)
      [...]
      Kernel driver in use: igb_uio

#. Load the kernel module:

   .. code-block:: console

      modprobe qede

   Example output:

   .. code-block:: console

      systemd-udevd[4848]: renamed network interface eth0 to ens5f0
      systemd-udevd[4848]: renamed network interface eth1 to ens5f1

#. Bring up the PF ports:

   .. code-block:: console

      ifconfig ens5f0 up
      ifconfig ens5f1 up

#. Create VF device(s):

   Echo the number of VFs to be created into ``"sriov_numvfs"`` sysfs entry
   of the parent PF.

   Example output:

   .. code-block:: console

      echo 2 > /sys/devices/pci0000:00/0000:00:03.0/0000:81:00.0/sriov_numvfs


#. Assign VF MAC address:

   Assign MAC address to the VF using iproute2 utility. The syntax is::

      ip link set <PF iface> vf <VF id> mac <macaddr>

   Example output:

   .. code-block:: console

      ip link set ens5f0 vf 0 mac 52:54:00:2f:9d:e8


#. PCI Passthrough:

   The VF devices may be passed through to the guest VM using ``virt-manager`` or
   ``virsh``. QEDE PMD should be used to bind the VF devices in the guest VM
   using the instructions outlined in the Application notes above.
