The command "meson build" causes a deprecation warning with meson 0.64.0. WARNING: Running the setup command as `meson [options]` instead of `meson setup [options]` is ambiguous and deprecated. Therefore fix the examples in the documentation.

ARMv8 Crypto Poll Mode Driver
|
|
=============================
|
|
|
|
This code provides the initial implementation of the ARMv8 crypto PMD.
|
|
The driver uses ARMv8 cryptographic extensions to process chained crypto
|
|
operations in an optimized way. The core functionality is provided by
|
|
a low-level library, written in the assembly code.
|
|
|
|
Features
|
|
--------
|
|
|
|
ARMv8 Crypto PMD has support for the following algorithm pairs:
|
|
|
|
Supported cipher algorithms:
|
|
|
|
* ``RTE_CRYPTO_CIPHER_AES_CBC``
|
|
|
|
Supported authentication algorithms:
|
|
|
|
* ``RTE_CRYPTO_AUTH_SHA1_HMAC``
|
|
* ``RTE_CRYPTO_AUTH_SHA256_HMAC``
|
|
|
|
Installation
|
|
------------
|
|
|
|
To build DPDK with this virtual crypto PMD, the user is required to:
|
|
|
|
* Download AArch64 crypto library source code from
|
|
`here <https://github.com/ARM-software/AArch64cryptolib>`_.
|
|
|
|
* Build the ``AArch64cryptolib`` library:
|
|
|
|
.. code-block:: console
|
|
|
|
make
|
|
|
|
* Add path to `libAArch64crypto.pc` in `PKG_CONFIG_PATH` environment variable:
|
|
|
|
.. code-block:: console
|
|
|
|
export PKG_CONFIG_PATH=<path_to_AArch64cryptolib>/pkgconfig/:$PKG_CONFIG_PATH
|
|
|
|
* Build DPDK:
|
|
|
|
.. code-block:: console
|
|
|
|
meson setup build
|
|
ninja -C build
|
|
|
|
The corresponding device can be created only if the following features
|
|
are supported by the CPU:
|
|
|
|
* ``RTE_CPUFLAG_AES``
|
|
* ``RTE_CPUFLAG_SHA1``
|
|
* ``RTE_CPUFLAG_SHA2``
|
|
* ``RTE_CPUFLAG_NEON``
|
|
|
|
Initialization
|
|
--------------
|
|
|
|
Use ``--vdev "crypto_armv8"`` in the EAL options to create virtual crypto device.
|
|
|
|
User can use app/test application to check how to use this PMD and to verify
|
|
crypto processing.
|
|
|
|
Test name is cryptodev_sw_armv8_autotest.
|
|
|
|
Limitations
|
|
-----------
|
|
|
|
* Maximum number of sessions is 2048.
|
|
* Only chained operations are supported.
|
|
* AES-128-CBC is the only supported cipher variant.
|
|
* Cipher input data has to be a multiple of 16 bytes.
|
|
* Digest input data has to be a multiple of 8 bytes.
