Subject: [PATCH v6 26/27] net/thunderx: updated driver documentation and release notes
Date: Fri, 17 Jun 2016 18:59:53 +0530 [thread overview]
Message-ID: <1466170194-28393-27-git-send-email-jerin.jacob@caviumnetworks.com> (raw)
In-Reply-To: <1466170194-28393-1-git-send-email-jerin.jacob@caviumnetworks.com>
Updated doc/guides/nics/overview.rst, doc/guides/nics/thunderx.rst
and release notes
Changed "*" to "P" in overview.rst to capture the partially supported
feature as "*" creating alignment issues with Sphinx table

+Running testpmd
+~~~~~~~~~~~~~~~
+
+This section demonstrates how to launch ``testpmd`` with ThunderX NIC VF device
+managed by ``librte_pmd_thunderx_nicvf`` in the Linux operating system.
+
+#. Load ``vfio-pci`` driver:
+
+ .. code-block:: console
+
+ modprobe vfio-pci
+
+ .. _thunderx_vfio_noiommu:
+
+#. Enable **VFIO-NOIOMMU** mode (optional):
+
+ .. code-block:: console
+
+ echo 1 > /sys/module/vfio/parameters/enable_unsafe_noiommu_mode
+
+ .. note::
+
+ **VFIO-NOIOMMU** is required only when running in VM context and should not be enabled otherwise.
+ See also :ref:`SR-IOV: Prerequisites and sample Application Notes <thunderx_sriov_example>`.
+
+#. Bind the ThunderX NIC VF device to ``vfio-pci`` loaded in the previous step:

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Current ThunderX NIC PF/VF kernel modules maps each physical Ethernet port
+automatically to virtual function (VF) and presented them as PCIe-like SR-IOV device.
+This section provides instructions to configure SR-IOV with Linux OS.
+
+#. Verify PF devices capabilities using ``lspci``:
+
+ .. code-block:: console
+
+ lspci -vvv
+
+ Example output:
+
+ .. code-block:: console
+
+ 0002:01:00.0 Ethernet controller: Cavium Networks Device a01e (rev 01)
+ ...
+ Capabilities: [100 v1] Alternative Routing-ID Interpretation (ARI)
+ ...
+ Capabilities: [180 v1] Single Root I/O Virtualization (SR-IOV)
+ ...
+ Kernel driver in use: thunder-nic
+ ...
+
+ .. note::
+
+ Unless ``thunder-nic`` driver is in use make sure your kernel config includes ``CONFIG_THUNDER_NIC_PF`` setting.
+
+#. Verify VF devices capabilities and drivers using ``lspci``:
+
+ .. code-block:: console
+
+ lspci -vvv
+
+ Example output:
+
+ .. code-block:: console
+
+ 0002:01:00.1 Ethernet controller: Cavium Networks Device 0011 (rev 01)
+ ...
+ Capabilities: [100 v1] Alternative Routing-ID Interpretation (ARI)

+ ...
+ Kernel driver in use: thunder-nicvf
+ ...
+
+ .. note::
+
+ Unless ``thunder-nicvf`` driver is in use make sure your kernel config includes ``CONFIG_THUNDER_NIC_VF`` setting.
+
+#. Verify PF/VF bind using ``dpdk_nic_bind.py``:
+
+ .. code-block:: console
+
+ ./tools/dpdk_nic_bind.py --status
+
+ Example output:
+
+ .. code-block:: console
+
+ ...
+ 0002:01:00.0 'Device a01e' if= drv=thunder-nic unused=vfio-pci
+ 0002:01:00.1 'Device 0011' if=eth0 drv=thunder-nicvf unused=vfio-pci
+ 0002:01:00.2 'Device 0011' if=eth1 drv=thunder-nicvf unused=vfio-pci
+ ...
+
+#. Load ``vfio-pci`` driver:
+
+ .. code-block:: console
+
+ modprobe vfio-pci
+
+#. Bind VF devices to ``vfio-pci`` using ``dpdk_nic_bind.py``:
+
+ .. code-block:: console
+
+ ./tools/dpdk_nic_bind.py --bind vfio-pci 0002:01:00.1
+ ./tools/dpdk_nic_bind.py --bind vfio-pci 0002:01:00.2
+
+#. Verify VF bind using ``dpdk_nic_bind.py``:
+
+ .. code-block:: console
+
+ ./tools/dpdk_nic_bind.py --status
+
+ Example output:
+
+ .. code-block:: console

+ ...
+ 0002:01:00.0 'Device a01e' if= drv=thunder-nic unused=vfio-pci
+ ...
+
+#. Pass VF device to VM context (PCIe Passthrough):
+
+ The VF devices may be passed through to the guest VM using qemu or
+ virt-manager or virsh etc.
+ ``librte_pmd_thunderx_nicvf`` or ``thunder-nicvf`` should be used to bind
+ the VF devices in the guest VM in :ref:`VFIO-NOIOMMU <thunderx_vfio_noiommu>` mode.
+
+ Example qemu guest launch command:
+
+ .. code-block:: console
+
+ sudo qemu-system-aarch64 -name vm1 \
+ -machine virt,gic_version=3,accel=kvm,usb=off \
+ -cpu host -m 4096 \
+ -smp 4,sockets=1,cores=8,threads=1 \
+ -nographic -nodefaults \
+ -kernel <kernel image> \
+ -append "root=/dev/vda console=ttyAMA0 rw hugepagesz=512M hugepages=3" \
+ -device vfio-pci,host=0002:01:00.1 \
+ -drive file=<rootfs.ext3>,if=none,id=disk1,format=raw \
+ -device virtio-blk-device,scsi=off,drive=disk1,id=virtio-disk1,bootindex=1 \
+ -netdev tap,id=net0,ifname=tap0,script=/etc/qemu-ifup_thunder \
+ -device virtio-net-device,netdev=net0 \
+ -serial stdio \
+ -mem-path /dev/huge
+
+#. Refer to section :ref:`Running testpmd <thunderx_testpmd_example>` for instruction
+ how to launch ``testpmd`` application.
+
+Limitations
+-----------
+
+CRC striping
+~~~~~~~~~~~~
+
+The ThunderX SoC family NICs strip the CRC for every packets coming into the
+host interface. So, CRC will be stripped even when the
+``rxmode.hw_strip_crc`` member is set to 0 in ``struct rte_eth_conf``.
+
+Maximum packet length
+~~~~~~~~~~~~~~~~~~~~~
+
+The ThunderX SoC family NICs support a maximum of a 9K jumbo frame. The value
+is fixed and cannot be changed. So, even when the ``rxmode.max_rx_pkt_len``
+member of ``struct rte_eth_conf`` is set to a value lower than 9200, frames
+up to 9200 bytes can still reach the host interface.
+
+Maximum packet segments
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The ThunderX SoC family NICs support up to 12 segments per packet when working
+in scatter/gather mode. So, setting MTU will result with ``EINVAL`` when the
+frame size does not fit in the maximum number of segments.
+
+Limited VFs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ThunderX SoC family NICs has 128VFs and each VF has 8/8 queues
+for RX/TX respectively. Current driver implementation has one to one mapping
+between physical port and VF hence only limited VFs can be used.
