The dpaa2 eventdev is an implementation of the eventdev API, that provides a wide range of the eventdev features. The eventdev relies on a dpaa2 hw to perform event scheduling.
More information can be found at NXP Official Website.
The DPAA2 EVENTDEV implements many features in the eventdev API;
See NXP QorIQ DPAA2 Board Support Package for setup information
Currently supported by DPDK:
Note
Some part of fslmc bus code (mc flib - object library) routines are dual licensed (BSD & GPLv2).
The following options can be modified in the config file. Please note that enabling debugging options may affect system performance.
CONFIG_RTE_LIBRTE_PMD_DPAA2_EVENTDEV (default y)
Toggle compilation of the lrte_pmd_dpaa2_event driver.
To compile the DPAA2 EVENTDEV PMD for Linux arm64 gcc target, run the following make command:
cd <DPDK-source-directory>
make config T=arm64-dpaa2-linuxapp-gcc install
The dpaa2 eventdev is exposed as a vdev device which consists of a set of dpcon devices and dpci devices. On EAL initialization, dpcon and dpci devices will be probed and then vdev device can be created from the application code by
Example:
./your_eventdev_application --vdev="event_dpaa2"
For enabling logs, use the following EAL parameter:
./your_eventdev_application <EAL args> --log-level=pmd.event.dpaa2,<level>
Using eventdev.dpaa2 as log matching criteria, all Event PMD logs can be enabled which are lower than logging level.
DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the Supported DPAA2 SoCs.
DPAA2 EVENTDEV can support only one eventport per core.
