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
|
|
------------
|
|
|
|
In order to enable this virtual crypto PMD, user must:
|
|
|
|
* Download ARMv8 crypto library source code from
|
|
`here <https://github.com/caviumnetworks/armv8_crypto>`_
|
|
|
|
* Export the environmental variable ARMV8_CRYPTO_LIB_PATH with
|
|
the path where the ``armv8_crypto`` library was downloaded
|
|
or cloned.
|
|
|
|
* Build the library by invoking:
|
|
|
|
.. code-block:: console
|
|
|
|
make -C $ARMV8_CRYPTO_LIB_PATH/
|
|
|
|
* Set CONFIG_RTE_LIBRTE_PMD_ARMV8_CRYPTO=y in
|
|
config/defconfig_arm64-armv8a-linux-gcc
|
|
|
|
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
|
|
--------------
|
|
|
|
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.
