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``
64 * ``RTE_CRYPTO_AUTH_SHA1_HMAC``
65 * ``RTE_CRYPTO_AUTH_SHA224_HMAC``
66 * ``RTE_CRYPTO_AUTH_SHA256_HMAC``
67 * ``RTE_CRYPTO_AUTH_SHA384_HMAC``
68 * ``RTE_CRYPTO_AUTH_SHA512_HMAC``
69 * ``RTE_CRYPTO_AUTH_MD5_HMAC``
73 * ``RTE_CRYPTO_AEAD_AES_GCM``
81 Whitelisting & Blacklisting
82 ---------------------------
84 For blacklisting a DPAA device, following commands can be used.
86 .. code-block:: console
88 <dpdk app> <EAL args> -b "dpaa_bus:dpaa-secX" -- ...
89 e.g. "dpaa_bus:dpaa-sec0"
91 or to disable all 4 SEC devices
92 -b "dpaa_sec:dpaa-sec0" -b "dpaa_sec:dpaa-sec1" -b "dpaa_sec:dpaa-sec2" -b "dpaa_sec:dpaa-sec3"
97 * Chained mbufs are not supported.
98 * Hash followed by Cipher mode is not supported
99 * Only supports the session-oriented API implementation (session-less APIs are not supported).
104 DPAA_SEC driver has similar pre-requisites as described in :ref:`dpaa_overview`.
105 The following dependencies are not part of DPDK and must be installed separately:
109 NXP Linux software development kit (SDK) includes support for the family
110 of QorIQ® ARM-Architecture-based system on chip (SoC) processors
111 and corresponding boards.
113 It includes the Linux board support packages (BSPs) for NXP SoCs,
114 a fully operational tool chain, kernel and board specific modules.
116 SDK and related information can be obtained from: `NXP QorIQ SDK <http://www.nxp.com/products/software-and-tools/run-time-software/linux-sdk/linux-sdk-for-qoriq-processors:SDKLINUX>`_.
118 * **DPDK Extras Scripts**
120 DPAA based resources can be configured easily with the help of ready scripts
121 as provided in the DPDK Extras repository.
123 `DPDK Extras Scripts <https://github.com/qoriq-open-source/dpdk-extras>`_.
125 Currently supported by DPDK:
128 * Supported architectures: **arm64 LE**.
130 * Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
132 Pre-Installation Configuration
133 ------------------------------
138 Basic DPAA config file options are described in :ref:`dpaa_overview`.
139 In addition to those, the following options can be modified in the ``config`` file
140 to enable DPAA_SEC PMD.
142 Please note that enabling debugging options may affect system performance.
144 * ``CONFIG_RTE_LIBRTE_PMD_DPAA_SEC`` (default ``n``)
145 By default it is only enabled in defconfig_arm64-dpaa-* config.
146 Toggle compilation of the ``librte_pmd_dpaa_sec`` driver.
148 * ``CONFIG_RTE_DPAA_SEC_PMD_MAX_NB_SESSIONS``
149 By default it is set as 2048 in defconfig_arm64-dpaa-* config.
150 It indicates Number of sessions to create in the session memory pool
151 on a single DPAA SEC device.
155 To compile the DPAA_SEC PMD for Linux arm64 gcc target, run the
156 following ``make`` command:
158 .. code-block:: console
160 cd <DPDK-source-directory>
161 make config T=arm64-dpaa-linuxapp-gcc install
166 For enabling logs, use the following EAL parameter:
168 .. code-block:: console
170 ./your_crypto_application <EAL args> --log-level=pmd.crypto.dpaa:<level>
172 Using ``pmd.crypto.dpaa`` as log matching criteria, all Crypto PMD logs can be
173 enabled which are lower than logging ``level``.
