MVPP2 Poll Mode Driver
======================
-The MVPP2 PMD (librte_pmd_mvpp2) provides poll mode driver support
+The MVPP2 PMD (**librte_net_mvpp2**) provides poll mode driver support
for the Marvell PPv2 (Packet Processor v2) 1/10 Gbps adapter.
Detailed information about SoCs that use PPv2 can be obtained here:
* https://www.marvell.com/embedded-processors/armada-70xx/
* https://www.marvell.com/embedded-processors/armada-80xx/
-.. Note::
-
- Due to external dependencies, this driver is disabled by default. It must
- be enabled manually by setting relevant configuration option manually.
- Please refer to `Config File Options`_ section for further details.
-
Features
--------
chance to start in a sane state.
- MUSDK architecture does not support changing configuration in run time.
- All nessesary configurations should be done before first dev_start().
+ All necessary configurations should be done before first dev_start().
- RX queue start/stop is not supported.
DPDK environment.
-Config File Options
--------------------
-
-The following options can be modified in the ``config`` file.
-
-- ``CONFIG_RTE_LIBRTE_MVPP2_PMD`` (default ``n``)
-
- Toggle compilation of the librte mvpp2 driver.
-
- .. Note::
-
- When MVPP2 PMD is enabled ``CONFIG_RTE_LIBRTE_MVNETA_PMD`` must be disabled
-
-
Building DPDK
-------------
MUSDK will be installed to `usr/local` under current directory.
For the detailed build instructions please consult ``doc/musdk_get_started.txt``.
-Before the DPDK build process the environmental variable ``LIBMUSDK_PATH`` with
-the path to the MUSDK installation directory needs to be exported.
+The path to the MUSDK installation directory needs to set in meson, shown in the
+command below.
For additional instructions regarding DPDK cross compilation please refer to :doc:`Cross compile DPDK for ARM64 <../linux_gsg/cross_build_dpdk_for_arm64>`.
.. code-block:: console
- export LIBMUSDK_PATH=<musdk>/usr/local
- export CROSS=<toolchain>/bin/aarch64-linux-gnu-
- export RTE_KERNELDIR=<kernel-dir>
- export RTE_TARGET=arm64-armv8a-linuxapp-gcc
+ meson -Dlib_musdk_dir=/path/to/musdk build ninja -C build
- make config T=arm64-armv8a-linuxapp-gcc
- sed -i "s/MVNETA_PMD=y/MVNETA_PMD=n/" build/.config
- sed -i "s/MVPP2_PMD=n/MVPP2_PMD=y/" build/.config
- make

.. _flowapi:
PPv2 offers packet classification capabilities via classifier engine which
can be configured via generic flow API offered by DPDK.
-For an additional description please refer to DPDK :ref:`Generic flow API <Generic_flow_API>`.
+
+The :ref:`flow_isolated_mode` is supported.
+
+For an additional description please refer to DPDK :doc:`../prog_guide/rte_flow`.

2. Create meter profile:
parent is called a non-leaf (root).
MVPP2 PMD supports two level hierarchy where level 0 represents ports and level 1 represents tx queues of a given port.
