      crypto: poly1305 - Add a four block AVX2 variant for x86_64 · b1ccc8f4

      consecutive Poly1305 blocks in parallel using AVX2 instructions.

      crypto: poly1305 - Add a SSE2 SIMD variant for x86_64 · c70f4abe
      Martin Willi authored
      Implements an x86_64 assembler driver for the Poly1305 authenticator. This
      single block variant holds the 130-bit integer in 5 32-bit words, but uses
      SSE to do two multiplications/additions in parallel.
      
      When calling updates with small blocks, the overhead for kernel_fpu_begin/
      kernel_fpu_end() negates the perfmance gain. We therefore use the
      poly1305-generic fallback for small updates.
      
      For large messages, throughput increases by ~5-10% compared to
      poly1305-generic:

      Martin Willi authored
      The AVX2 variant of ChaCha20 is used only for messages with >= 512 bytes
      length. With the existing test vectors, the implementation could not be
      tested. Due that lack of such a long official test vector, this one is
      self-generated using chacha20-generic.
