fallback mechanism in HASH drivers implimentetion

Hi , I am trying to understand the SHA1 (asynchronous) driver , I am not really sure regarding below mentioned scenarios,please can some help me with this? #1: When driver needs to use fallback mechanism and how does it work? #2: when do driver needs to use methods like import/export ? BR, Sris

Understanding HASH(SHA) Driver implementation

Hi , I am trying to analyze Linux Kernel Crypto Interface with respective to hashing(ahash for SHA1 in particular) . I am looking at omap-sham.c/atmel-sha.c as reference,which is in open source linux/driver/crypto.I need some inputs in understanding following . #1: If It need to handle a scenario
