      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:

      Adds individual ChaCha20 and Poly1305 and a combined rfc7539esp AEAD speed
      test using mode numbers 214, 321 and 213. For Poly1305 we add a specific
      speed template, as it expects the key prepended to the input data.
