MRVL Crypto Poll Mode Driver ============================ The MRVL CRYPTO PMD (**librte_crypto_mrvl_pmd**) provides poll mode crypto driver support by utilizing MUSDK library, which provides cryptographic operations acceleration by using Security Acceleration Engine (EIP197) directly from user-space with minimum overhead and high performance. Features -------- MRVL CRYPTO PMD has support for: * Symmetric crypto * Sym operation chaining * AES CBC (128) * AES CBC (192) * AES CBC (256) * AES CTR (128) * AES CTR (192) * AES CTR (256) * 3DES CBC * 3DES CTR * MD5 * MD5 HMAC * SHA1 * SHA1 HMAC * SHA256 * SHA256 HMAC * SHA384 * SHA384 HMAC * SHA512 * SHA512 HMAC * AES GCM (128) Limitations ----------- * Hardware only supports scenarios where ICV (digest buffer) is placed just after the authenticated data. Other placement will result in error. * Before running crypto test suite it is advised to increase limit of opened files: .. code-block:: console ulimit -n 20000 Installation ------------ MRVL CRYPTO PMD driver compilation is disabled by default due to external dependencies. Currently there are two driver specific compilation options in ``config/common_base`` available: - ``CONFIG_RTE_LIBRTE_MRVL_CRYPTO`` (default ``n``) Toggle compilation of the librte_pmd_mrvl driver. - ``CONFIG_RTE_LIBRTE_MRVL_CRYPTO_DEBUG`` (default ``n``) Toggle display of debugging messages. During compilation external MUSDK library, which provides direct access to Marvell's EIP197 cryptographic engine, is necessary. Library sources are available `here `__. Alternatively, prebuilt library can be downloaded from `Marvell Extranet `_. Once approval has been granted, library can be found by typing ``musdk`` in the search box. For MUSDK library build instructions please refer to ``doc/musdk_get_started.txt`` in library sources directory. MUSDK requires out of tree kernel modules to work. Kernel tree needed to build them is available `here `__. Initialization -------------- After successfully building MRVL CRYPTO PMD, the following modules need to be loaded: .. code-block:: console insmod musdk_uio.ko insmod mvpp2x_sysfs.ko insmod mv_pp_uio.ko insmod mv_sam_uio.ko insmod crypto_safexcel.ko - `musdk_uio.ko`, `mv_pp2_uio.ko` and `mv_sam_uio.ko` are distributed together with MUSDK library. - `crypto_safexcel.ko` is an in-kernel module. - `mvpp2x_sysfs.ko` can be build from sources available `here `__. The following parameters (all optional) are exported by the driver: * max_nb_queue_pairs: maximum number of queue pairs in the device (8 by default). * max_nb_sessions: maximum number of sessions that can be created (2048 by default). * socket_id: socket on which to allocate the device resources on. l2fwd-crypto example application can be used to verify MRVL CRYPTO PMD operation: .. code-block:: console ./l2fwd-crypto --vdev=net_mrvl,iface=eth0 --vdev=crypto_mrvl -- \ --cipher_op ENCRYPT --cipher_algo aes-cbc \ --cipher_key 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:0f \ --auth_op GENERATE --auth_algo sha1-hmac \ --auth_key 10:11:12:13:14:15:16:17:18:19:1a:1b:1c:1d:1e:1f Example output: .. code-block:: console [...] AAD: at [0x7f253ceb80], len= P ID 0 configuration ---- Port mode : KR MAC status : disabled Link status : link up Port speed : 10G Port duplex : full Port: Egress enable tx_port_num=16 qmap=0x1 PORT: Port0 - link P ID 0 configuration ---- Port mode : KR MAC status : disabled Link status : link down Port speed : 10G Port duplex : full Port: Egress enable tx_port_num=16 qmap=0x1 Port 0, MAC address: 00:50:43:02:21:20 Checking link statusdone Port 0 Link Up - speed 0 Mbps - full-duplex Lcore 0: RX port 0 Allocated session pool on socket 0 eip197: 0:0 registers: paddr: 0xf2880000, vaddr: 0x0x7f56a80000 DMA buffer (131136 bytes) for CDR #0 allocated: paddr = 0xb0585e00, vaddr = 0x7f09384e00 DMA buffer (131136 bytes) for RDR #0 allocated: paddr = 0xb05a5f00, vaddr = 0x7f093a4f00 DMA buffers allocated for 2049 operations.
