33 ======================
35 The QEDE poll mode driver library (**librte_pmd_qede**) implements support
36 for **QLogic FastLinQ QL4xxxx 10G/25G/40G/50G/100G Intelligent Ethernet Adapters (IEA) and Converged Network Adapters (CNA)** family of adapters as well as SR-IOV virtual functions (VF). It is supported on
37 several standard Linux distros like RHEL7.x, SLES12.x and Ubuntu.
38 It is compile-tested under FreeBSD OS.
40 More information can be found at `QLogic Corporation's Website

82 - Requires storm firmware version **8.30.12.0**. Firmware may be available
83 inbox in certain newer Linux distros under the standard directory
84 ``E.g. /lib/firmware/qed/qed_init_values-8.30.12.0.bin``
85 If the required firmware files are not available then download it from
86 `QLogic Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
87 For downloading firmware file, select adapter category, model and DPDK Poll Mode Driver.
89 - Requires management firmware (MFW) version **8.30.x.x** or higher to be
90 flashed on to the adapter. If the required management firmware is not
91 available then download from
92 `QLogic Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
93 For downloading firmware upgrade utility, select adapter category, model and Linux distro.
94 To flash the management firmware refer to the instructions in the QLogic Firmware Upgrade Utility Readme document.
96 - SR-IOV requires Linux PF driver version **8.20.x.x** or higher.
97 If the required PF driver is not available then download it from
98 `QLogic Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
99 For downloading PF driver, select adapter category, model and Linux distro.
105 - For better performance, it is recommended to use 4K or higher RX/TX rings.
110 The following options can be modified in the ``.config`` file. Please note that
111 enabling debugging options may affect system performance.
113 - ``CONFIG_RTE_LIBRTE_QEDE_PMD`` (default **y**)
115 Toggle compilation of QEDE PMD driver.
117 - ``CONFIG_RTE_LIBRTE_QEDE_DEBUG_INFO`` (default **n**)
119 Toggle display of generic debugging messages.
121 - ``CONFIG_RTE_LIBRTE_QEDE_DEBUG_DRIVER`` (default **n**)
123 Toggle display of ecore related messages.
125 - ``CONFIG_RTE_LIBRTE_QEDE_DEBUG_TX`` (default **n**)
127 Toggle display of transmit fast path run-time messages.
129 - ``CONFIG_RTE_LIBRTE_QEDE_DEBUG_RX`` (default **n**)
131 Toggle display of receive fast path run-time messages.
133 - ``CONFIG_RTE_LIBRTE_QEDE_VF_TX_SWITCH`` (default **"y"**)
135 A knob to control per-VF Tx switching feature.
137 - ``CONFIG_RTE_LIBRTE_QEDE_FW`` (default **""**)
139 Gives absolute path of firmware file.
140 ``Eg: "/lib/firmware/qed/qed_init_values-8.30.12.0.bin"``
141 Empty string indicates driver will pick up the firmware file
142 from the default location /lib/firmware/qed.
143 CAUTION this option is more for custom firmware, it is not
144 recommended for use under normal condition.
146 Driver compilation and testing
147 ------------------------------
149 Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
152 SR-IOV: Prerequisites and Sample Application Notes
153 --------------------------------------------------
155 This section provides instructions to configure SR-IOV with Linux OS.
157 **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.
159 #. Verify SR-IOV and ARI capability is enabled on the adapter using ``lspci``:
161 .. code-block:: console
167 .. code-block:: console
170 Capabilities: [1b8 v1] Alternative Routing-ID Interpretation (ARI)
172 Capabilities: [1c0 v1] Single Root I/O Virtualization (SR-IOV)
174 Kernel driver in use: igb_uio
176 #. Load the kernel module:
178 .. code-block:: console
184 .. code-block:: console
186 systemd-udevd[4848]: renamed network interface eth0 to ens5f0
187 systemd-udevd[4848]: renamed network interface eth1 to ens5f1
189 #. Bring up the PF ports:
191 .. code-block:: console
196 #. Create VF device(s):
198 Echo the number of VFs to be created into ``"sriov_numvfs"`` sysfs entry
203 .. code-block:: console
205 echo 2 > /sys/devices/pci0000:00/0000:00:03.0/0000:81:00.0/sriov_numvfs
208 #. Assign VF MAC address:
210 Assign MAC address to the VF using iproute2 utility. The syntax is::
212 ip link set <PF iface> vf <VF id> mac <macaddr>
216 .. code-block:: console
218 ip link set ens5f0 vf 0 mac 52:54:00:2f:9d:e8
223 The VF devices may be passed through to the guest VM using ``virt-manager`` or
224 ``virsh``. QEDE PMD should be used to bind the VF devices in the guest VM
225 using the instructions from Driver compilation and testing section above.
229 (Enable QEDE_DEBUG_INFO=y to view informational messages):
231 Refer to the document
232 :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>` to run
233 ``testpmd`` application.
