Prerequisites
-------------
-There are three main pre-requisities for executing DPAA2 PMD on a DPAA2
-compatible board:
-
-1. **ARM 64 Tool Chain**
-
- For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/6.4-2017.08/aarch64-linux-gnu/>`_.
-
-2. **Linux Kernel**
-
- It can be obtained from `NXP's Github hosting <https://github.com/qoriq-open-source/linux>`_.
-
-3. **Rootfile system**
-
- Any *aarch64* supporting filesystem can be used. For example,
- Ubuntu 15.10 (Wily) or 16.04 LTS (Xenial) userland which can be obtained
- from `here <http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04.1-base-arm64.tar.gz>`_.
-
-As an alternative method, DPAA2 PMD can also be executed using images provided
-as part of SDK from NXP. The SDK includes all the above prerequisites necessary
-to bring up a DPAA2 board.
-
-The following dependencies are not part of DPDK and must be installed
-separately:
-
-- **NXP Linux SDK**
-
- NXP Linux software development kit (SDK) includes support for family
- of QorIQ® ARM-Architecture-based system on chip (SoC) processors
- and corresponding boards.
-
- It includes the Linux board support packages (BSPs) for NXP SoCs,
- a fully operational tool chain, kernel and board specific modules.
-
- SDK and related information can be obtained from: `NXP QorIQ SDK <http://www.nxp.com/products/software-and-tools/run-time-software/linux-sdk/linux-sdk-for-qoriq-processors:SDKLINUX>`_.
-
-- **DPDK Extra Scripts**
-
- DPAA2 based resources can be configured easily with the help of ready scripts
- as provided in the DPDK Extra repository.
-
- `DPDK Extras Scripts <https://github.com/qoriq-open-source/dpdk-extras>`_.
+See :doc:`../platform/dpaa2` for setup information
Currently supported by DPDK:
-- NXP SDK **17.08+**.
-- MC Firmware version **10.3.1** and higher.
+- NXP LSDK **19.08+**.
+- MC Firmware version **10.18.0** and higher.
- Supported architectures: **arm64 LE**.
- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
The following options can be modified in the ``config`` file.
Please note that enabling debugging options may affect system performance.
-- ``CONFIG_RTE_LIBRTE_FSLMC_BUS`` (default ``n``)
+- ``CONFIG_RTE_LIBRTE_FSLMC_BUS`` (default ``y``)
- By default it is enabled only for defconfig_arm64-dpaa2-* config.
Toggle compilation of the ``librte_bus_fslmc`` driver.
-- ``CONFIG_RTE_LIBRTE_DPAA2_PMD`` (default ``n``)
+- ``CONFIG_RTE_LIBRTE_DPAA2_PMD`` (default ``y``)
- By default it is enabled only for defconfig_arm64-dpaa2-* config.
Toggle compilation of the ``librte_pmd_dpaa2`` driver.
- ``CONFIG_RTE_LIBRTE_DPAA2_DEBUG_DRIVER`` (default ``n``)
Toggle display of debugging messages/logic
-- ``CONFIG_RTE_LIBRTE_DPAA2_USE_PHYS_IOVA`` (default ``y``)
+- ``CONFIG_RTE_LIBRTE_DPAA2_USE_PHYS_IOVA`` (default ``n``)
Toggle to use physical address vs virtual address for hardware accelerators.
Done

+* Use dev arg option ``drv_loopback=1`` to loopback packets at
+ driver level. Any packet received will be reflected back by the
+ driver on same port. e.g. ``fslmc:dpni.1,drv_loopback=1``
+
+* Use dev arg option ``drv_no_prefetch=1`` to disable prefetching
+ of the packet pull command which is issued in the previous cycle.
+ e.g. ``fslmc:dpni.1,drv_no_prefetch=1``
