4 | help | ||
5 | Enables the driver module for Freescale's Cryptographic Accelerator | ||
6 | and Assurance Module (CAAM), also known as the SEC version 4 (SEC4). | ||
7 | This module adds a job ring operation interface, and configures h/w | ||
8 | to operate as a DPAA component automatically, depending | ||
9 | on h/w feature availability. | ||
10 | |||
11 | To compile this driver as a module, choose M here: the module | ||
12 | will be called caam. | ||

46 | raising an interrupt, in the range 1-255. Note that a selection | ||
47 | of 1 functionally defeats the coalescing feature, and a selection | ||
