CN9K REE Regexdev Driver
|
||
|
|
==============================
|
||
|
|
|
||
|
|
The CN9K REE PMD (**librte_regex_cn9k**) provides poll mode
|
||
|
|
regexdev driver support for the inbuilt regex device found in the **Marvell CN9K**
|
||
|
|
SoC family.
|
||
|
|
|
||
|
|
More information about CN9K SoC can be found at `Marvell Official Website
|
||
|
|
<https://www.marvell.com/embedded-processors/infrastructure-processors/>`_.

Features
|
||
|
|
--------
|
||
|
|
|
||
|
|
Features of the CN9K REE PMD are:
|
||
|
|
|
||
|
|
- 36 queues
|
||
|
|
- Up to 254 matches for each regex operation
|
||
|
|
|
||
|
|
Prerequisites and Compilation procedure
|
||
|
|
---------------------------------------
|
||
|
|
|
||
|
|
See :doc:`../platform/cnxk` for setup information.
|
||
|
|
|
||
|
|
Device Setup
|
||
|
|
------------
|
||
|
|
|
||
|
|
The CN9K REE devices will need to be bound to a user-space IO driver
|
||
|
|
for use. The script ``dpdk-devbind.py`` script included with DPDK can be
|
||
|
|
used to view the state of the devices and to bind them to a suitable
|
||
|
|
DPDK-supported kernel driver. When querying the status of the devices,
|
||
|
|
they will appear under the category of "REGEX devices", i.e. the command
|
||
|
|
``dpdk-devbind.py --status-dev regex`` can be used to see the state of
|
||
|
|
those devices alone.
