4 AESN-NI Multi Buffer Crypto Poll Mode Driver
5 ============================================
8 The AESNI MB PMD (**librte_crypto_aesni_mb**) provides poll mode crypto driver
9 support for utilizing Intel multi buffer library, see the white paper
10 `Fast Multi-buffer IPsec Implementations on IntelĀ® Architecture Processors
11 <https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/fast-multi-buffer-ipsec-implementations-ia-processors-paper.pdf>`_.
13 The AES-NI MB PMD has current only been tested on Fedora 21 64-bit with gcc.
15 The AES-NI MB PMD supports synchronous mode of operation with
16 ``rte_cryptodev_sym_cpu_crypto_process`` function call.

85 To build DPDK with the AESNI_MB_PMD the user is required to download the multi-buffer
86 library from `here <https://github.com/01org/intel-ipsec-mb>`_
87 and compile it on their user system before building DPDK.
88 The latest version of the library supported by this PMD is v0.55, which
89 can be downloaded from `<https://github.com/01org/intel-ipsec-mb/archive/v0.55.zip>`_.
91 .. code-block:: console
96 The library requires NASM to be built. Depending on the library version, it might
97 require a minimum NASM version (e.g. v0.54 requires at least NASM 2.14).
99 NASM is packaged for different OS. However, on some OS the version is too old,
100 so a manual installation is required. In that case, NASM can be downloaded from
101 `NASM website <https://www.nasm.us/pub/nasm/releasebuilds/?C=M;O=D>`_.
102 Once it is downloaded, extract it and follow these steps:
104 .. code-block:: console
112 Compilation of the Multi-Buffer library is broken when GCC < 5.0, if library <= v0.53.
113 If a lower GCC version than 5.0, the workaround proposed by the following link
114 should be used: `<https://github.com/intel/intel-ipsec-mb/issues/40>`_.
116 As a reference, the following table shows a mapping between the past DPDK versions
117 and the Multi-Buffer library version supported by them:
119 .. _table_aesni_mb_versions:
121 .. table:: DPDK and Multi-Buffer library version compatibility
123 ============== ============================
124 DPDK version Multi-buffer library version
125 ============== ============================
126 2.2 - 16.11 0.43 - 0.44
128 17.05 - 17.08 0.45 - 0.48
131 18.05 - 19.02 0.49 - 0.52
134 ============== ============================
140 In order to enable this virtual crypto PMD, user must:
142 * Build the multi buffer library (explained in Installation section).
144 To use the PMD in an application, user must:
146 * Call rte_vdev_init("crypto_aesni_mb") within the application.
148 * Use --vdev="crypto_aesni_mb" in the EAL options, which will call rte_vdev_init() internally.
150 The following parameters (all optional) can be provided in the previous two calls:
152 * socket_id: Specify the socket where the memory for the device is going to be allocated
153 (by default, socket_id will be the socket where the core that is creating the PMD is running on).
155 * max_nb_queue_pairs: Specify the maximum number of queue pairs in the device (8 by default).
157 * max_nb_sessions: Specify the maximum number of sessions that can be created (2048 by default).
161 .. code-block:: console
163 ./dpdk-l2fwd-crypto -l 1 -n 4 --vdev="crypto_aesni_mb,socket_id=0,max_nb_sessions=128" \
164 -- -p 1 --cdev SW --chain CIPHER_HASH --cipher_algo "aes-cbc" --auth_algo "sha1-hmac"
169 For AES Counter mode (AES-CTR), the library supports two different sizes for Initialization
172 * 12 bytes: used mainly for IPsec, as it requires 12 bytes from the user, which internally
173 are appended the counter block (4 bytes), which is set to 1 for the first block
174 (no padding required from the user)
176 * 16 bytes: when passing 16 bytes, the library will take them and use the last 4 bytes
177 as the initial counter block for the first block.
