Broadcom FlexSparc Crypto Poll Mode Driver
|
|
==========================================
|
|
|
|
The FlexSparc crypto poll mode driver (BCMFS PMD) provides support for offloading
|
|
cryptographic operations to the Broadcom SoCs having FlexSparc4 unit.
|
|
Detailed information about SoCs can be found at `Broadcom Official Website
|
|
<https://www.broadcom.com/products/ethernet-connectivity/network-adapters/smartnic>`__.
|
|
|
|

Installation
|
|
------------
|
|
Information about kernel, rootfs and toolchain can be found at
|
|
`Broadcom Official Website <https://www.broadcom.com/products/ethernet-connectivity
|
|
/network-adapters/smartnic/stingray-software>`__.
|
|
|
|
.. Note::
|
|
To execute BCMFS PMD, it must be compiled with VFIO_PRESENT flag on the
|
|
compiling platform and same gets enabled in rte_vfio.h.
|
|
|
|
The BCMFS PMD may be compiled natively on a Stingray platform or
|
|
cross-compiled on an x86 platform. For example, below commands can be executed
|
|
for cross compiling on x86 platform.
|
|
|
|
.. code-block:: console
|
|
|
|
cd <DPDK-source-directory>
|
|
meson <dest-dir> --cross-file config/arm/arm64_stingray_linux_gcc
|
|
cd <dest-dir>
|
|
ninja
|
|
|
|
Initialization
|
|
--------------
|
|
The supported platform devices should be present in the
|
|
*/sys/bus/platform/devices/fs<version>/<dev_name>* path on the booted kernel.
|
|
To get BCMFS PMD executing, device node must be owned by VFIO platform module only.
|
|
For example, below commands can be run to get hold of a device node by VFIO.
|
|
|
|
.. code-block:: console
|
|
|
|
SETUP_SYSFS_DEV_NAME=67000000.crypto_mbox
|
|
io_device_name="vfio-platform"
|
|
echo $io_device_name > /sys/bus/platform/devices/${SETUP_SYSFS_DEV_NAME}/driver_override
|
|
echo ${SETUP_SYSFS_DEV_NAME} > /sys/bus/platform/drivers_probe
|
|
|
|
Limitations
|
|
-----------
|
|
|
|
* The session-oriented APIs are supported but the session-less APIs are not.
|
|
* CCM is not supported.
|
|
|
|
Testing
|
|
-------
|
|
|
|
The symmetric crypto operations on BCMFS PMD may be verified by running the test
|
|
application:
|
|
|
|
.. code-block:: console
|
|
|
|
./dpdk-test
|
|
RTE>>cryptodev_bcmfs_autotest
