6 NXP DPAA CAAM (DPAA_SEC)
7 ========================
9 The DPAA_SEC PMD provides poll mode crypto driver support for NXP DPAA CAAM
15 SEC is the SOC's security engine, which serves as NXP's latest cryptographic
16 acceleration and offloading hardware. It combines functions previously
17 implemented in separate modules to create a modular and scalable acceleration
18 and assurance engine. It also implements block encryption algorithms, stream
19 cipher algorithms, hashing algorithms, public key algorithms, run-time
20 integrity checking, and a hardware random number generator. SEC performs
21 higher-level cryptographic operations than previous NXP cryptographic
22 accelerators. This provides significant improvement to system level performance.
24 DPAA_SEC is one of the hardware resource in DPAA Architecture. More information
25 on DPAA Architecture is described in :ref:`dpaa_overview`.
27 DPAA_SEC PMD is one of DPAA drivers which interacts with QBMAN to create,
28 configure and destroy the device instance using queue pair with CAAM portal.
30 DPAA_SEC PMD also uses some of the other hardware resources like buffer pools,
31 queues, queue portals to store and to enqueue/dequeue data to the hardware SEC.
36 SEC provides platform assurance by working with SecMon, which is a companion
37 logic block that tracks the security state of the SOC. SEC is programmed by
38 means of descriptors (not to be confused with frame descriptors (FDs)) that
39 indicate the operations to be performed and link to the message and
40 associated data. SEC incorporates two DMA engines to fetch the descriptors,
41 read the message data, and write the results of the operations. The DMA
42 engine provides a scatter/gather capability so that SEC can read and write
43 data scattered in memory. SEC may be configured by means of software for
44 dynamic changes in byte ordering. The default configuration for this version
45 of SEC is little-endian mode.
50 The DPAA PMD has support for:
54 * ``RTE_CRYPTO_CIPHER_3DES_CBC``
55 * ``RTE_CRYPTO_CIPHER_AES128_CBC``
56 * ``RTE_CRYPTO_CIPHER_AES192_CBC``
57 * ``RTE_CRYPTO_CIPHER_AES256_CBC``
58 * ``RTE_CRYPTO_CIPHER_AES128_CTR``
59 * ``RTE_CRYPTO_CIPHER_AES192_CTR``
60 * ``RTE_CRYPTO_CIPHER_AES256_CTR``
61 * ``RTE_CRYPTO_CIPHER_SNOW3G_UEA2``
62 * ``RTE_CRYPTO_CIPHER_ZUC_EEA3``
66 * ``RTE_CRYPTO_AUTH_SHA1_HMAC``
67 * ``RTE_CRYPTO_AUTH_SHA224_HMAC``
68 * ``RTE_CRYPTO_AUTH_SHA256_HMAC``
69 * ``RTE_CRYPTO_AUTH_SHA384_HMAC``
70 * ``RTE_CRYPTO_AUTH_SHA512_HMAC``
71 * ``RTE_CRYPTO_AUTH_SNOW3G_UIA2``
72 * ``RTE_CRYPTO_AUTH_MD5_HMAC``
73 * ``RTE_CRYPTO_AUTH_ZUC_EIA3``
77 * ``RTE_CRYPTO_AEAD_AES_GCM``
88 For blocking a DPAA device, following commands can be used.
90 .. code-block:: console
92 <dpdk app> <EAL args> -b "dpaa:dpaa_sec-X" -- ...
93 e.g. "dpaa:dpaa_sec-1"
95 or to disable all 4 SEC devices
96 -b "dpaa:dpaa_sec-1" -b "dpaa:dpaa_sec-2" -b "dpaa:dpaa_sec-3" -b "dpaa:dpaa_sec-4"
101 * Hash followed by Cipher mode is not supported
102 * Only supports the session-oriented API implementation (session-less APIs are not supported).
107 DPAA_SEC driver has similar pre-requisites as described in :ref:`dpaa_overview`.
109 See :doc:`../platform/dpaa` for setup information
112 - Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
118 For enabling logs, use the following EAL parameter:
120 .. code-block:: console
122 ./your_crypto_application <EAL args> --log-level=pmd.crypto.dpaa:<level>
124 Using ``pmd.crypto.dpaa`` as log matching criteria, all Crypto PMD logs can be
125 enabled which are lower than logging ``level``.
127 Enabling debug prints
128 ---------------------
130 Use dev arg option ``drv_dump_mode=x`` to dump useful debug prints on HW sec
131 error. There are 3 dump modes available 0, 1 and 2. Mode 0 means no dump print
132 on error, mode 1 means dump HW error code and mode 2 means dump HW error code
133 along with other useful debugging information like session, queue, descriptor
135 e.g. ``dpaa_bus:dpaa_sec-1,drv_dump_mode=1``
