26. ZTE Storage Data Accelerator (ZSDA) Poll Mode Driver

The ZSDA crypto PMD provides poll mode Cipher and Hash driver support for the following hardware accelerator devices:

  • ZTE Processing accelerators 1cf2

26.1. Features

The ZSDA SYM PMD has support for:

Cipher algorithms:

  • RTE_CRYPTO_CIPHER_AES_XTS

  • RTE_CRYPTO_CIPHER_SM4_XTS

Hash algorithms:

  • RTE_CRYPTO_AUTH_SHA1

  • RTE_CRYPTO_AUTH_SHA224

  • RTE_CRYPTO_AUTH_SHA256

  • RTE_CRYPTO_AUTH_SHA384

  • RTE_CRYPTO_AUTH_SHA512

  • RTE_CRYPTO_AUTH_SM3

26.2. Limitations

  • Only supports the session-oriented API implementation (session-less API is not supported).

  • No BSD and Windows support.

  • Queue-pairs are thread-safe on Intel CPUs but queues are not: within a single queue-pair all enqueues to the Tx queue must be done from one thread and all dequeues from the Rx queue must be done from one thread, but enqueues and dequeues may be done in different threads.

26.3. Installation

The ZSDA crypto service is built by default with a standard DPDK build.

26.4. Testing

ZSDA SYM crypto PMD can be tested by running the test application:

cd ./<build_dir>/app/test
./dpdk-test -l1 -n1 -a <your zsda bdf>
