- HW offloaded `ethdev Rx queue` to `eventdev event queue` packet injection
- Support Rx interrupt
- Inline IPsec processing support
+- :ref:`Traffic Management API <otx2_tmapi>`
Prerequisites
-------------
See :doc:`../platform/octeontx2` for setup information.
-Compile time Config Options
----------------------------
-
-The following options may be modified in the ``config`` file.
-
-- ``CONFIG_RTE_LIBRTE_OCTEONTX2_PMD`` (default ``y``)
-
- Toggle compilation of the ``librte_pmd_octeontx2`` driver.
Driver compilation and testing
------------------------------
Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
for details.
-To compile the OCTEON TX2 PMD for Linux arm64 gcc,
-use arm64-octeontx2-linux-gcc as target.
-
#. Running testpmd:
Follow instructions available in the document
.. code-block:: console
- ./build/app/testpmd -c 0x300 -w 0002:02:00.0 -- --portmask=0x1 --nb-cores=1 --port-topology=loop --rxq=1 --txq=1
+ ./<build_dir>/app/dpdk-testpmd -c 0x300 -w 0002:02:00.0 -- --portmask=0x1 --nb-cores=1 --port-topology=loop --rxq=1 --txq=1
EAL: Detected 24 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
With the above configuration, higig2 will be enabled on that port and the
traffic on this port should be higig2 traffic only. Supported switch header
- types are "higig2" and "dsa".
+ types are "higig2", "dsa" and "chlen90b".
- ``RSS tag as XOR`` (default ``0``)
Setting this flag to 1 to select the legacy mode.
For example to select the legacy mode(RSS tag adder as XOR)::
+
-w 0002:02:00.0,tag_as_xor=1
- ``Max SPI for inbound inline IPsec`` (default ``1``)
``ipsec_in_max_spi`` ``devargs`` parameter.
For example::
+
-w 0002:02:00.0,ipsec_in_max_spi=128
With the above configuration, application can enable inline IPsec processing
on 128 SAs (SPI 0-127).
+- ``Lock Rx contexts in NDC cache``
+
+ Lock Rx contexts in NDC cache by using ``lock_rx_ctx`` parameter.
+
+ For example::
+
+ -w 0002:02:00.0,lock_rx_ctx=1
+
+- ``Lock Tx contexts in NDC cache``
+
+ Lock Tx contexts in NDC cache by using ``lock_tx_ctx`` parameter.
+
+ For example::
+
+ -w 0002:02:00.0,lock_tx_ctx=1
+
.. note::
Above devarg parameters are configurable per device, user needs to pass the
parameters to all the PCIe devices if application requires to configure on
all the ethdev ports.
+- ``Lock NPA contexts in NDC``
+
+ Lock NPA aura and pool contexts in NDC cache.
+ The device args take hexadecimal bitmask where each bit represent the
+ corresponding aura/pool id.
+
+ For example::
+
+ -w 0002:02:00.0,npa_lock_mask=0xf
+
+.. _otx2_tmapi:
+
+Traffic Management API
+----------------------
+
+OCTEON TX2 PMD supports generic DPDK Traffic Management API which allows to
+configure the following features:
+
+#. Hierarchical scheduling
+#. Single rate - Two color, Two rate - Three color shaping
+
+Both DWRR and Static Priority(SP) hierarchial scheduling is supported.
+
+Every parent can have atmost 10 SP Children and unlimited DWRR children.
+
+Both PF & VF supports traffic management API with PF supporting 6 levels
+and VF supporting 5 levels of topology.
+
