14. Marvell NITROX Crypto Poll Mode Driver

The Nitrox crypto poll mode driver provides support for offloading cryptographic operations to the NITROX V security processor. Detailed information about the NITROX V security processor can be obtained here:

14.1. Features

Nitrox crypto PMD has support for:

Cipher algorithms:


Hash algorithms:


14.2. Limitations

  • AES_CBC Cipher Only combination is not supported.
  • 3DES Cipher Only combination is not supported.
  • Session-less APIs are not supported.

14.3. Installation

For compiling the Nitrox crypto PMD, please check if the CONFIG_RTE_LIBRTE_PMD_NITROX setting is set to y in config/common_base file.


14.4. Initialization

Nitrox crypto PMD depend on Nitrox kernel PF driver being installed on the platform. Nitrox PF driver is required to create VF devices which will be used by the PMD. Each VF device can enable one cryptodev PMD.

Nitrox kernel PF driver is available as part of CNN55XX-Driver SDK. The SDK and it’s installation instructions can be obtained from: Marvell Technical Documentation Portal.
