5 NXP DPAA2 Eventdev Driver
6 =========================
8 The dpaa2 eventdev is an implementation of the eventdev API, that provides a
9 wide range of the eventdev features. The eventdev relies on a dpaa2 hw to
10 perform event scheduling.
12 More information can be found at `NXP Official Website
13 <http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/qoriq-arm-processors:QORIQ-ARM>`_.
18 The DPAA2 EVENTDEV implements many features in the eventdev API;
20 - Hardware based event scheduler
37 There are three main pre-requisities for executing DPAA2 EVENTDEV on a DPAA2
40 1. **ARM 64 Tool Chain**
42 For example, the `*aarch64* Linaro Toolchain <https://releases.linaro.org/components/toolchain/binaries/4.9-2017.01/aarch64-linux-gnu>`_.
46 It can be obtained from `NXP's Github hosting <https://github.com/qoriq-open-source/linux>`_.
48 3. **Rootfile system**
50 Any *aarch64* supporting filesystem can be used. For example,
51 Ubuntu 15.10 (Wily) or 16.04 LTS (Xenial) userland which can be obtained
52 from `here <http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04.1-base-arm64.tar.gz>`_.
54 As an alternative method, DPAA2 EVENTDEV can also be executed using images provided
55 as part of SDK from NXP. The SDK includes all the above prerequisites necessary
56 to bring up a DPAA2 board.
58 The following dependencies are not part of DPDK and must be installed
63 NXP Linux software development kit (SDK) includes support for family
64 of QorIQ® ARM-Architecture-based system on chip (SoC) processors
65 and corresponding boards.
67 It includes the Linux board support packages (BSPs) for NXP SoCs,
68 a fully operational tool chain, kernel and board specific modules.
70 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>`_.
72 - **DPDK Extra Scripts**
74 DPAA2 based resources can be configured easily with the help of ready scripts
75 as provided in the DPDK Extra repository.
77 `DPDK Extras Scripts <https://github.com/qoriq-open-source/dpdk-extras>`_.
79 Currently supported by DPDK:
82 - MC Firmware version **10.0.0** and higher.
83 - Supported architectures: **arm64 LE**.
85 - Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
89 Some part of fslmc bus code (mc flib - object library) routines are
90 dual licensed (BSD & GPLv2).
92 Pre-Installation Configuration
93 ------------------------------
98 The following options can be modified in the ``config`` file.
99 Please note that enabling debugging options may affect system performance.
101 - ``CONFIG_RTE_LIBRTE_PMD_DPAA2_EVENTDEV`` (default ``y``)
103 Toggle compilation of the ``lrte_pmd_dpaa2_event`` driver.
105 - ``CONFIG_RTE_LIBRTE_PMD_DPAA2_EVENTDEV_DEBUG`` (default ``n``)
107 Toggle display of generic debugging messages
112 To compile the DPAA2 EVENTDEV PMD for Linux arm64 gcc target, run the
113 following ``make`` command:
115 .. code-block:: console
117 cd <DPDK-source-directory>
118 make config T=arm64-dpaa2-linuxapp-gcc install
123 The dpaa2 eventdev is exposed as a vdev device which consists of a set of dpcon
124 devices and dpci devices. On EAL initialization, dpcon and dpci devices will be
125 probed and then vdev device can be created from the application code by
127 * Invoking ``rte_vdev_init("event_dpaa2")`` from the application
129 * Using ``--vdev="event_dpaa2"`` in the EAL options, which will call
130 rte_vdev_init() internally
134 .. code-block:: console
136 ./your_eventdev_application --vdev="event_dpaa2"
144 DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
145 ``Supported DPAA2 SoCs``.
150 DPAA2 EVENTDEV driver requires event port 'x' to be used on core 'x'.
