DPAA Poll Mode Driver
=====================
this pool.
+Whitelisting & Blacklisting
+---------------------------
+
+For blacklisting a DPAA device, following commands can be used.
+
+ .. code-block:: console
+
+ <dpdk app> <EAL args> -b "dpaa_bus:fmX-macY" -- ...
+ e.g. "dpaa_bus:fm1-mac4"
+
Supported DPAA SoCs
-------------------
Prerequisites
-------------
-There are three main pre-requisities for executing DPAA PMD on a DPAA
-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>`_.
-
-4. **FMC Tool**
-
- Before any DPDK application can be executed, the Frame Manager Configuration
- Tool (FMC) need to be executed to set the configurations of the queues. This
- includes the queue state, RSS and other policies.
- This tool can be obtained from `NXP (Freescale) Public Git Repository <https://github.com/qoriq-open-source/fmc>`_.
-
- This tool needs configuration files which are available in the
- :ref:`DPDK Extra Scripts <extra_scripts>`, described below for DPDK usages.
+See :doc:`../platform/dpaa` for setup information
-As an alternative method, DPAA 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 DPAA 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>`_.
-
-
-.. _extra_scripts:
-
-- **DPDK Extra Scripts**
-
- DPAA 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>`_.
-
-Currently supported by DPDK:
-
-- NXP SDK **2.0+**.
-- Supported architectures: **arm64 LE**.
- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>`
to setup the basic DPDK environment.
In case the application is configured to use lesser number of queues than
configured above, it might result in packet loss (because of distribution).
+- ``DPAA_PUSH_QUEUES_NUMBER`` (default 4)
+
+ This defines the number of High performance queues to be used for ethdev Rx.
+ These queues use one private HW portal per queue configured, so they are
+ limited in the system. The first configured ethdev queues will be
+ automatically be assigned from the these high perf PUSH queues. Any queue
+ configuration beyond that will be standard Rx queues. The application can
+ choose to change their number if HW portals are limited.
+ The valid values are from '0' to '4'. The valuse shall be set to '0' if the
+ application want to use eventdev with DPAA device.
