arm64/crypto: GHASH secure hash using ARMv8 Crypto Extensions This is a port to ARMv8 (Crypto Extensions) of the Intel implementation of the GHASH Secure Hash (used in the Galois/Counter chaining mode). It relies on the optional PMULL/PMULL2 instruction (polynomial multiply long, what Intel call carry-less multiply).

arm64/crypto: AES-ECB/CBC/CTR/XTS using ARMv8 NEON and Crypto Extensions This adds ARMv8 implementations of AES in ECB, CBC, CTR and XTS modes, both for ARMv8 with Crypto Extensions and for plain ARMv8 NEON. The Crypto Extensions version can only run on ARMv8 implementations that have support for these optional extensions. The plain NEON version is a table based yet time invariant implementation. All S-box substitutions are performed in parallel, leveraging the wide range of ARMv8's tbl/tbx instructions, and the huge NEON register file, which can comfortably hold the entire S-box and still have room to spare for doing the actual computations. The key expansion routines were borrowed from aes_generic. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Herbert Xu <herbert@gondor.apana.org.au>

arm64: crypto: increase AES interleave to 4x 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>

crypto: crc32 - Add ARM64 CRC32 hw accelerated module This module registers a crc32 algorithm and a crc32c algorithm that use the optional CRC32 and CRC32C instructions in ARMv8. Tested on AMD Seattle. Improvement compared to crc32c-generic algorithm: TCRYPT CRC32C speed test shows ~450% speedup. Simple dd write tests to btrfs filesystem show ~30% speedup.
