This patch increases the interleave factor for parallel AES modes to 4x. This improves performance on Cortex-A57 by ~35%. This is due to the 3-cycle latency of AES instructions on the A57's relatively deep pipeline (compared to Cortex-A53 where the AES instruction latency is only 2 cycles). At the same time, disable inline expansion of the core AES functions, as the performance benefit of this feature is negligible. Measured on AMD Seattle (using tcrypt.ko mode=500 sec=1): Baseline (2x interleave, inline expansion) ------------------------------------------ testing speed of async cbc(aes) (cbc-aes-ce) decryption test 4 (128 bit key, 8192 byte blocks): 95545 operations in 1 seconds test 14 (256 bit key, 8192 byte blocks): 68496 operations in 1 seconds This patch (4x interleave, no inline expansion) ----------------------------------------------- testing speed of async cbc(aes) (cbc-aes-ce) decryption test 4 (128 bit key, 8192 byte blocks): 124735 operations in 1 seconds test 14 (256 bit key, 8192 byte blocks): 92328 operations in 1 seconds Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
