Subject: [PATCH] crypto: tcrypt - add skcipher speed for given alg
Date: Thu,  9 May 2024 12:36:11 +0100
Message-ID: <20240509113703.578583-1-sergey.portnoy@intel.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Allow to run skcipher speed for given algorithm.
Two separate cases are added to cover ENCRYPT and DECRYPT
directions.

Example:
   modprobe tcrypt mode=611 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)
