Subject: [PATCH v3] crypto: tcrypt - add skcipher speed for given alg
Date: Fri,  7 Jun 2024 15:30:48 +0100
Message-ID: <20240607143128.2740633-1-sergey.portnoy@intel.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Allow to run skcipher speed for given algorithm.
Case 600 is modified to cover ENCRYPT and DECRYPT
directions.

Example:
   modprobe tcrypt mode=600 alg="qat_aes_xts" klen=32

If succeed, the performance numbers will be printed in dmesg:
   testing speed of multibuffer qat_aes_xts (qat_aes_xts) encryption
   test 0 (256 bit key, 16 byte blocks): 1 operation in 14596 cycles (16 bytes)
   ...
   test 6 (256 bit key, 4096 byte blocks): 1 operation in 8053 cycles (4096 bytes)

v2->v3

- modifying case 600, instead of using separate cases for
  encrypt/decrypt
