[PATCH 0/5] crypto: atmel-sha: fix registration issue and other bugs
From: Cyrille Pitchen
Date: Fri Jan 15 2016 - 09:49:11 EST
This series of patches fixes many issues such as the algo registration failure
or the broken support of context switches.
This series was applied to linux-next and tested on a sama5d2 xplained
ultra board. We now pass the tcrypt tests in the following modes:
- 2: sha1
- 6: sha256
- 11: sha384
- 12: sha512
- 33: sha224
The context switch fix was tested with a userspace program using the cryptodev
module. This single thread program computes the SHA256 hashes of many files
by splitting then into fixed size chunks. The chunks of each file are
processed by calling 'update' operations using a round robin algorithm.
However, the .import() / .export() implementation was NOT tested!
Nonetheless the last patch is needed to fix the registration issue, otherwise
atmel_sha_probe() would still fail.
