Add more optimized XTS code for aesni_intel in 64-bit mode, for smaller stack usage and boost for speed. tcrypt results, with Intel i5-2450M: 256-bit key enc dec 16B 0.98x 0.99x 64B 0.64x 0.63x 256B 1.29x 1.32x 1024B 1.54x 1.58x 8192B 1.57x 1.60x 512-bit key enc dec 16B 0.98x 0.99x 64B 0.60x 0.59x 256B 1.24x 1.25x 1024B 1.39x 1.42x 8192B 1.38x 1.42x I chose not to optimize smaller than block size of 256 bytes, since XTS is practically always used with data blocks of size 512 bytes. This is why performance is reduced in tcrypt for 64 byte long blocks. Cc: Huang Ying <ying.huang@intel.com> Signed-off-by:Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by:

Add more optimized XTS code for camellia-aesni-avx, for smaller stack usage and small boost for speed. tcrypt results, with Intel i5-2450M: enc dec 16B 1.10x 1.01x 64B 0.82x 0.77x 256B 1.14x 1.10x 1024B 1.17x 1.16x 8192B 1.10x 1.11x Since XTS is practically always used with data blocks of size 512 bytes or more, I chose to not make use of camellia-2way for block sized smaller than 256 bytes. This causes slower result in tcrypt for 64 bytes. Signed-off-by: -

This patch adds AVX optimized XTS-mode helper functions/macros and converts serpent-avx to use the new facilities. Benefits are slightly improved speed and reduced stack usage as use of temporary IV-array is avoided. tcrypt results, with Intel i5-2450M: enc dec 16B 1.00x 1.00x 64B 1.00x 1.00x 256B 1.04x 1.06x 1024B 1.09x 1.09x 8192B 1.10x 1.09x Signed-off-by: -

These modules require AVX support in assembler, so add new check to Makefile for this. Other option would be to use CONFIG_AS_AVX inside source files, but that would result dummy/empty/no-fuctionality modules being created. Signed-off-by:

This change is required for post SEC-5.0 devices which have RNG4. Setting RDB in security configuration register allows CAAM to use the "Random Data Buffer" to be filled by a single request. The Random Data Buffer is large enough for ten packets to get their IVs from a single request. If the Random Data Buffer is not enabled, then each IV causes a separate request, and RNG4 hardware cannot keep up resulting in lower IPSEC throughput if random IVs are used. Signed-off-by:

The Kconfig entry for CAAM's hash algorithm implementations has always selected CRYPTO_AHASH. But there's no corresponding Kconfig symbol. It seems it was intended to select CRYPTO_HASH, like other crypto drivers do. That would apparently (indirectly) select CRYPTO_HASH2, which would enable the ahash functionality this driver uses.
