|

Once the required VFs are enabled, to be accessible from DPDK, VFs need to be
|
||||
bound to vfio-pci driver.
|
||||
|
||||
Device Setup
|
||||
------------
|
||||
|
||||
The OCTEON TX2 SDP End Point VF 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 "Misc (rawdev)
|
||||
devices", i.e. the command ``dpdk-devbind.py --status-dev misc`` can be
|
||||
used to see the state of those devices alone.
|
||||
|
||||
Device Configuration
|
||||
--------------------
|
||||
|
||||
Configuring SDP EP rawdev device is done using the ``rte_rawdev_configure()``
|
||||
API, which takes the mempool as parameter. PMD uses this pool to send/receive
|
||||
packets to/from the HW.
|
||||
|
||||
The following code shows how the device is configured
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
struct sdp_rawdev_info config = {0};
|
||||
struct rte_rawdev_info rdev_info = {.dev_private = &config};
|
||||
config.enqdeq_mpool = (void *)rte_mempool_create(...);
|
||||
|
||||
rte_rawdev_configure(dev_id, (rte_rawdev_obj_t)&rdev_info);
