MLX5 poll mode driver
=====================
The MLX5 poll mode driver library (**librte_pmd_mlx5**) provides support
for **Mellanox ConnectX-4**, **Mellanox ConnectX-4 Lx** and **Mellanox
ConnectX-5** families of 10/25/40/50/100 Gb/s adapters as well as their
virtual functions (VF) in SR-IOV context.
Information and documentation about these adapters can be found on the
`Mellanox website <http://www.mellanox.com>`__. Help is also provided by the
`Mellanox community <http://community.mellanox.com/welcome>`__.
There is also a `section dedicated to this poll mode driver
<http://www.mellanox.com/page/products_dyn?product_family=209&mtag=pmd_for_dpdk>`__.
.. note::
Due to external dependencies, this driver is disabled by default. It must
be enabled manually by setting ``CONFIG_RTE_LIBRTE_MLX5_PMD=y`` and
recompiling DPDK.
Implementation details
----------------------
Besides its dependency on libibverbs (that implies libmlx5 and associated
kernel support), librte_pmd_mlx5 relies heavily on system calls for control
operations such as querying/updating the MTU and flow control parameters.
For security reasons and robustness, this driver only deals with virtual
memory addresses. The way resources allocations are handled by the kernel
combined with hardware specifications that allow it to handle virtual memory
addresses directly ensure that DPDK applications cannot access random
physical memory (or memory that does not belong to the current process).
This capability allows the PMD to coexist with kernel network interfaces
which remain functional, although they stop receiving unicast packets as
long as they share the same MAC address.
This means legacy linux control tools (for example: ethtool, ifconfig and
more) can operate on the same network interfaces that owned by the DPDK
application.
Enabling librte_pmd_mlx5 causes DPDK applications to be linked against
libibverbs.
Features
--------
- Multi arch support: x86_64, POWER8, ARMv8.
- Multiple TX and RX queues.
- Support for scattered TX and RX frames.
- IPv4, IPv6, TCPv4, TCPv6, UDPv4 and UDPv6 RSS on any number of queues.
- Several RSS hash keys, one for each flow type.
- Configurable RETA table.
- Support for multiple MAC addresses.
- VLAN filtering.
- RX VLAN stripping.
- TX VLAN insertion.
- RX CRC stripping configuration.
- Promiscuous mode.
- Multicast promiscuous mode.
- Hardware checksum offloads.
- Flow director (RTE_FDIR_MODE_PERFECT, RTE_FDIR_MODE_PERFECT_MAC_VLAN and
RTE_ETH_FDIR_REJECT).
- Flow API.
- Multiple process.
- KVM and VMware ESX SR-IOV modes are supported.
- RSS hash result is supported.
- Hardware TSO.
- Hardware checksum TX offload for VXLAN and GRE.
- RX interrupts.
- Statistics query including Basic, Extended and per queue.
- Rx HW timestamp.
- Tunnel types: VXLAN, L3 VXLAN, VXLAN-GPE, GRE.
- Tunnel HW offloads: packet type, inner/outer RSS, IP and UDP checksum verification.
Limitations
-----------
- For secondary process:
- Forked secondary process not supported.
- All mempools must be initialized before rte_eth_dev_start().
- Flow pattern without any specific vlan will match for vlan packets as well:
When VLAN spec is not specified in the pattern, the matching rule will be created with VLAN as a wild card.
Meaning, the flow rule::
flow create 0 ingress pattern eth / vlan vid is 3 / ipv4 / end ...
Will only match vlan packets with vid=3. and the flow rules::
flow create 0 ingress pattern eth / ipv4 / end ...
Or::
flow create 0 ingress pattern eth / vlan / ipv4 / end ...
Will match any ipv4 packet (VLAN included).
- A multi segment packet must have less than 6 segments in case the Tx burst function
is set to multi-packet send or Enhanced multi-packet send. Otherwise it must have
less than 50 segments.
- Count action for RTE flow is **only supported in Mellanox OFED**.
- Flows with a VXLAN Network Identifier equal (or ends to be equal)
to 0 are not supported.
- VXLAN TSO and checksum offloads are not supported on VM.
- VF: flow rules created on VF devices can only match traffic targeted at the
configured MAC addresses (see ``rte_eth_dev_mac_addr_add()``).
.. note::
MAC addresses not already present in the bridge table of the associated
kernel network device will be added and cleaned up by the PMD when closing
the device. In case of ungraceful program termination, some entries may
remain present and should be removed manually by other means.
Statistics
----------
MLX5 supports various of methods to report statistics:
Port statistics can be queried using ``rte_eth_stats_get()``. The port statistics are through SW only and counts the number of packets received or sent successfully by the PMD.
Extended statistics can be queried using ``rte_eth_xstats_get()``. The extended statistics expose a wider set of counters counted by the device. The extended port statistics counts the number of packets received or sent successfully by the port. As Mellanox NICs are using the :ref:`Bifurcated Linux Driver <linux_gsg_linux_drivers>` those counters counts also packet received or sent by the Linux kernel. The counters with ``_phy`` suffix counts the total events on the physical port, therefore not valid for VF.
Finally per-flow statistics can by queried using ``rte_flow_query`` when attaching a count action for specific flow. The flow counter counts the number of packets received successfully by the port and match the specific flow.
Configuration
-------------
Compilation options
~~~~~~~~~~~~~~~~~~~
These options can be modified in the ``.config`` file.
- ``CONFIG_RTE_LIBRTE_MLX5_PMD`` (default **n**)
Toggle compilation of librte_pmd_mlx5 itself.
- ``CONFIG_RTE_LIBRTE_MLX5_DLOPEN_DEPS`` (default **n**)
Build PMD with additional code to make it loadable without hard
dependencies on **libibverbs** nor **libmlx5**, which may not be installed
on the target system.
In this mode, their presence is still required for it to run properly,
however their absence won't prevent a DPDK application from starting (with
``CONFIG_RTE_BUILD_SHARED_LIB`` disabled) and they won't show up as
missing with ``ldd(1)``.
It works by moving these dependencies to a purpose-built rdma-core "glue"
plug-in which must either be installed in a directory whose name is based
on ``CONFIG_RTE_EAL_PMD_PATH`` suffixed with ``-glue`` if set, or in a
standard location for the dynamic linker (e.g. ``/lib``) if left to the
default empty string (``""``).
This option has no performance impact.
- ``CONFIG_RTE_LIBRTE_MLX5_DEBUG`` (default **n**)
Toggle debugging code and stricter compilation flags. Enabling this option
adds additional run-time checks and debugging messages at the cost of
lower performance.
- ``CONFIG_RTE_LIBRTE_MLX5_TX_MP_CACHE`` (default **8**)
Maximum number of cached memory pools (MPs) per TX queue. Each MP from
which buffers are to be transmitted must be associated to memory regions
(MRs). This is a slow operation that must be cached.
This value is always 1 for RX queues since they use a single MP.
Environment variables
~~~~~~~~~~~~~~~~~~~~~
- ``MLX5_GLUE_PATH``
A list of directories in which to search for the rdma-core "glue" plug-in,
separated by colons or semi-colons.
Only matters when compiled with ``CONFIG_RTE_LIBRTE_MLX5_DLOPEN_DEPS``
enabled and most useful when ``CONFIG_RTE_EAL_PMD_PATH`` is also set,
since ``LD_LIBRARY_PATH`` has no effect in this case.
- ``MLX5_PMD_ENABLE_PADDING``
Enables HW packet padding in PCI bus transactions.
When packet size is cache aligned and CRC stripping is enabled, 4 fewer
bytes are written to the PCI bus. Enabling padding makes such packets
aligned again.
In cases where PCI bandwidth is the bottleneck, padding can improve
performance by 10%.
This is disabled by default since this can also decrease performance for
unaligned packet sizes.
- ``MLX5_SHUT_UP_BF``
Configures HW Tx doorbell register as IO-mapped.
By default, the HW Tx doorbell is configured as a write-combining register.
The register would be flushed to HW usually when the write-combining buffer
becomes full, but it depends on CPU design.
Except for vectorized Tx burst routines, a write memory barrier is enforced
after updating the register so that the update can be immediately visible to
HW.
When vectorized Tx burst is called, the barrier is set only if the burst size
is not aligned to MLX5_VPMD_TX_MAX_BURST. However, setting this environmental
variable will bring better latency even though the maximum throughput can
slightly decline.
Run-time configuration
~~~~~~~~~~~~~~~~~~~~~~
- librte_pmd_mlx5 brings kernel network interfaces up during initialization
because it is affected by their state. Forcing them down prevents packets
reception.
- **ethtool** operations on related kernel interfaces also affect the PMD.
- ``rxq_cqe_comp_en`` parameter [int]
A nonzero value enables the compression of CQE on RX side. This feature
allows to save PCI bandwidth and improve performance. Enabled by default.
Supported on:
- x86_64 with ConnectX-4, ConnectX-4 LX and ConnectX-5.
- POWER8 and ARMv8 with ConnectX-4 LX and ConnectX-5.
- ``txq_inline`` parameter [int]
Amount of data to be inlined during TX operations. Improves latency.
Can improve PPS performance when PCI back pressure is detected and may be
useful for scenarios involving heavy traffic on many queues.
Because additional software logic is necessary to handle this mode, this
option should be used with care, as it can lower performance when back
pressure is not expected.
- ``txqs_min_inline`` parameter [int]
Enable inline send only when the number of TX queues is greater or equal
to this value.
This option should be used in combination with ``txq_inline`` above.
On ConnectX-4, ConnectX-4 LX and ConnectX-5 without Enhanced MPW:
- Disabled by default.
- In case ``txq_inline`` is set recommendation is 4.
On ConnectX-5 with Enhanced MPW:
- Set to 8 by default.
- ``txq_mpw_en`` parameter [int]
A nonzero value enables multi-packet send (MPS) for ConnectX-4 Lx and
enhanced multi-packet send (Enhanced MPS) for ConnectX-5. MPS allows the
TX burst function to pack up multiple packets in a single descriptor
session in order to save PCI bandwidth and improve performance at the
cost of a slightly higher CPU usage. When ``txq_inline`` is set along
with ``txq_mpw_en``, TX burst function tries to copy entire packet data
on to TX descriptor instead of including pointer of packet only if there
is enough room remained in the descriptor. ``txq_inline`` sets
per-descriptor space for either pointers or inlined packets. In addition,
Enhanced MPS supports hybrid mode - mixing inlined packets and pointers
in the same descriptor.
This option cannot be used with certain offloads such as ``DEV_TX_OFFLOAD_TCP_TSO,
DEV_TX_OFFLOAD_VXLAN_TNL_TSO, DEV_TX_OFFLOAD_GRE_TNL_TSO, DEV_TX_OFFLOAD_VLAN_INSERT``.
When those offloads are requested the MPS send function will not be used.
It is currently only supported on the ConnectX-4 Lx and ConnectX-5
families of adapters. Enabled by default.
- ``txq_mpw_hdr_dseg_en`` parameter [int]
A nonzero value enables including two pointers in the first block of TX
descriptor. This can be used to lessen CPU load for memory copy.
Effective only when Enhanced MPS is supported. Disabled by default.
- ``txq_max_inline_len`` parameter [int]
Maximum size of packet to be inlined. This limits the size of packet to
be inlined. If the size of a packet is larger than configured value, the
packet isn't inlined even though there's enough space remained in the
descriptor. Instead, the packet is included with pointer.
Effective only when Enhanced MPS is supported. The default value is 256.
- ``tx_vec_en`` parameter [int]
A nonzero value enables Tx vector on ConnectX-5 only NIC if the number of
global Tx queues on the port is lesser than MLX5_VPMD_MIN_TXQS.
This option cannot be used with certain offloads such as ``DEV_TX_OFFLOAD_TCP_TSO,
DEV_TX_OFFLOAD_VXLAN_TNL_TSO, DEV_TX_OFFLOAD_GRE_TNL_TSO, DEV_TX_OFFLOAD_VLAN_INSERT``.
When those offloads are requested the MPS send function will not be used.
Enabled by default on ConnectX-5.
- ``rx_vec_en`` parameter [int]
A nonzero value enables Rx vector if the port is not configured in
multi-segment otherwise this parameter is ignored.
Enabled by default.
- ``vf_nl_en`` parameter [int]
A nonzero value enables Netlink requests from the VF to add/remove MAC
addresses or/and enable/disable promiscuous/all multicast on the Netdevice.
Otherwise the relevant configuration must be run with Linux iproute2 tools.
This is a prerequisite to receive this kind of traffic.
Enabled by default, valid only on VF devices ignored otherwise.
- ``l3_vxlan_en`` parameter [int]
A nonzero value allows L3 VXLAN and VXLAN-GPE flow creation. To enable
L3 VXLAN or VXLAN-GPE, users has to configure firmware and enable this
parameter. This is a prerequisite to receive this kind of traffic.
Disabled by default.
Firmware configuration
~~~~~~~~~~~~~~~~~~~~~~
- L3 VXLAN and VXLAN-GPE destination UDP port
.. code-block:: console
mlxconfig -d <mst device> set IP_OVER_VXLAN_EN=1
mlxconfig -d <mst device> set IP_OVER_VXLAN_PORT=<udp dport>
Verify configurations are set:
.. code-block:: console
mlxconfig -d <mst device> query | grep IP_OVER_VXLAN
IP_OVER_VXLAN_EN True(1)
IP_OVER_VXLAN_PORT <udp dport>
Prerequisites
-------------
This driver relies on external libraries and kernel drivers for resources
allocations and initialization. The following dependencies are not part of
DPDK and must be installed separately:
- **libibverbs**
User space Verbs framework used by librte_pmd_mlx5. This library provides
a generic interface between the kernel and low-level user space drivers
such as libmlx5.
It allows slow and privileged operations (context initialization, hardware
resources allocations) to be managed by the kernel and fast operations to
never leave user space.
- **libmlx5**
Low-level user space driver library for Mellanox ConnectX-4/ConnectX-5
devices, it is automatically loaded by libibverbs.
This library basically implements send/receive calls to the hardware
queues.
- **Kernel modules**
They provide the kernel-side Verbs API and low level device drivers that
manage actual hardware initialization and resources sharing with user
space processes.
Unlike most other PMDs, these modules must remain loaded and bound to
their devices:
- mlx5_core: hardware driver managing Mellanox ConnectX-4/ConnectX-5
devices and related Ethernet kernel network devices.
- mlx5_ib: InifiniBand device driver.
- ib_uverbs: user space driver for Verbs (entry point for libibverbs).
- **Firmware update**
Mellanox OFED releases include firmware updates for ConnectX-4/ConnectX-5
adapters.
Because each release provides new features, these updates must be applied to
match the kernel modules and libraries they come with.
.. note::
Both libraries are BSD and GPL licensed. Linux kernel modules are GPL
licensed.

Quick Start Guide on OFED
-------------------------
1. Download latest Mellanox OFED. For more info check the `prerequisites`_.
2. Install the required libraries and kernel modules either by installing
only the required set, or by installing the entire Mellanox OFED:
.. code-block:: console
./mlnxofedinstall --upstream-libs --dpdk
3. Verify the firmware is the correct one:
.. code-block:: console
ibv_devinfo
4. Verify all ports links are set to Ethernet:
.. code-block:: console
mlxconfig -d <mst device> query | grep LINK_TYPE
LINK_TYPE_P1 ETH(2)
LINK_TYPE_P2 ETH(2)
Link types may have to be configured to Ethernet:
.. code-block:: console
mlxconfig -d <mst device> set LINK_TYPE_P1/2=1/2/3
* LINK_TYPE_P1=<1|2|3> , 1=Infiniband 2=Ethernet 3=VPI(auto-sense)
For hypervisors verify SR-IOV is enabled on the NIC:
.. code-block:: console
mlxconfig -d <mst device> query | grep SRIOV_EN
SRIOV_EN True(1)
If needed, set enable the set the relevant fields:
.. code-block:: console
mlxconfig -d <mst device> set SRIOV_EN=1 NUM_OF_VFS=16
mlxfwreset -d <mst device> reset
5. Restart the driver:
.. code-block:: console
/etc/init.d/openibd restart
or:
.. code-block:: console
service openibd restart
If link type was changed, firmware must be reset as well:
.. code-block:: console
mlxfwreset -d <mst device> reset
For hypervisors, after reset write the sysfs number of virtual functions
needed for the PF.
To dynamically instantiate a given number of virtual functions (VFs):
.. code-block:: console
echo [num_vfs] > /sys/class/infiniband/mlx5_0/device/sriov_numvfs
6. Compile DPDK and you are ready to go. See instructions on
:ref:`Development Kit Build System <Development_Kit_Build_System>`
Performance tuning
------------------
1. Configure aggressive CQE Zipping for maximum performance:
.. code-block:: console
mlxconfig -d <mst device> s CQE_COMPRESSION=1
To set it back to the default CQE Zipping mode use:
.. code-block:: console
mlxconfig -d <mst device> s CQE_COMPRESSION=0
2. In case of virtualization:
- Make sure that hypervisor kernel is 3.16 or newer.
- Configure boot with ``iommu=pt``.
- Use 1G huge pages.
- Make sure to allocate a VM on huge pages.
- Make sure to set CPU pinning.
3. Use the CPU near local NUMA node to which the PCIe adapter is connected,
for better performance. For VMs, verify that the right CPU
and NUMA node are pinned according to the above. Run:
.. code-block:: console
lstopo-no-graphics
to identify the NUMA node to which the PCIe adapter is connected.
4. If more than one adapter is used, and root complex capabilities allow
to put both adapters on the same NUMA node without PCI bandwidth degradation,
it is recommended to locate both adapters on the same NUMA node.
This in order to forward packets from one to the other without
NUMA performance penalty.
5. Disable pause frames:
.. code-block:: console
ethtool -A <netdev> rx off tx off
6. Verify IO non-posted prefetch is disabled by default. This can be checked
via the BIOS configuration. Please contact you server provider for more
information about the settings.
.. note::
On some machines, depends on the machine integrator, it is beneficial
to set the PCI max read request parameter to 1K. This can be
done in the following way:
To query the read request size use:
.. code-block:: console
setpci -s <NIC PCI address> 68.w
If the output is different than 3XXX, set it by:
.. code-block:: console
setpci -s <NIC PCI address> 68.w=3XXX
The XXX can be different on different systems. Make sure to configure
according to the setpci output.
Notes for testpmd
-----------------
Compared to librte_pmd_mlx4 that implements a single RSS configuration per
port, librte_pmd_mlx5 supports per-protocol RSS configuration.
Since ``testpmd`` defaults to IP RSS mode and there is currently no
command-line parameter to enable additional protocols (UDP and TCP as well
as IP), the following commands must be entered from its CLI to get the same
behavior as librte_pmd_mlx4:
.. code-block:: console
> port stop all
> port config all rss all
> port start all
Usage example
-------------
This section demonstrates how to launch **testpmd** with Mellanox
ConnectX-4/ConnectX-5 devices managed by librte_pmd_mlx5.
#. Load the kernel modules:
.. code-block:: console
modprobe -a ib_uverbs mlx5_core mlx5_ib
Alternatively if MLNX_OFED is fully installed, the following script can
be run:
.. code-block:: console
/etc/init.d/openibd restart
.. note::
User space I/O kernel modules (uio and igb_uio) are not used and do
not have to be loaded.
#. Make sure Ethernet interfaces are in working order and linked to kernel
verbs. Related sysfs entries should be present:
.. code-block:: console
ls -d /sys/class/net/*/device/infiniband_verbs/uverbs* | cut -d / -f 5
Example output:
.. code-block:: console
eth30
eth31
eth32
eth33
#. Optionally, retrieve their PCI bus addresses for whitelisting:
.. code-block:: console
{
for intf in eth2 eth3 eth4 eth5;
do
(cd "/sys/class/net/${intf}/device/" && pwd -P);
done;
} |
sed -n 's,.*/\(.*\),-w \1,p'
Example output:
.. code-block:: console
-w 0000:05:00.1
-w 0000:06:00.0
-w 0000:06:00.1
-w 0000:05:00.0
#. Request huge pages:
.. code-block:: console
echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages/nr_hugepages
#. Start testpmd with basic parameters:
.. code-block:: console
testpmd -l 8-15 -n 4 -w 05:00.0 -w 05:00.1 -w 06:00.0 -w 06:00.1 -- --rxq=2 --txq=2 -i
Example output:
.. code-block:: console
