#
# The module implements "4-bit" GCM GHASH function and underlying
# single multiplication operation in GF(2^128). "4-bit" means that
# it uses 256 bytes per-key table [+128 bytes shared table]. GHASH
# function features so called "528B" variant utilizing additional
# 256+16 bytes of per-key storage [+512 bytes shared table].
# Performance results are for this streamed GHASH subroutine and are
# expressed in cycles per processed byte, less is better:
#
# gcc 3.4.x(*) assembler
#
# P4 28.6 14.0 +100%
# Opteron 19.3 7.7 +150%
# Core2 17.8 8.1(**) +120%
# Atom 31.6 16.8 +88%
# VIA Nano 21.8 10.1 +115%
#
# (*) comparison is not completely fair, because C results are
# for vanilla "256B" implementation, while assembler results
# are for "528B";-)
# (**) it's mystery [to me] why Core2 result is not same as for
# Opteron;
# May 2010
#
# Add PCLMULQDQ version performing at 2.02 cycles per processed byte.
# See ghash-x86.pl for background information and details about coding
# techniques.
#
# Special thanks to David Woodhouse for providing access to a
# Westmere-based system on behalf of Intel Open Source Technology Centre.

#
# Overhaul: aggregate Karatsuba post-processing, improve ILP in
# reduction_alg9, increase reduction aggregate factor to 4x. As for
# the latter. ghash-x86.pl discusses that it makes lesser sense to
# increase aggregate factor. Then why increase here? Critical path
# consists of 3 independent pclmulqdq instructions, Karatsuba post-
# processing and reduction. "On top" of this we lay down aggregated
# multiplication operations, triplets of independent pclmulqdq's. As
# issue rate for pclmulqdq is limited, it makes lesser sense to
# aggregate more multiplications than it takes to perform remaining
# non-multiplication operations. 2x is near-optimal coefficient for
# contemporary Intel CPUs (therefore modest improvement coefficient),
# but not for Bulldozer. Latter is because logical SIMD operations
# are twice as slow in comparison to Intel, so that critical path is
# longer. A CPU with higher pclmulqdq issue rate would also benefit
# from higher aggregate factor...
#
# Westmere 1.78(+13%)
# Sandy Bridge 1.80(+8%)
# Ivy Bridge 1.80(+7%)
# Haswell 0.55(+93%) (if system doesn't support AVX)
# Broadwell 0.45(+110%)(if system doesn't support AVX)
# Skylake 0.44(+110%)(if system doesn't support AVX)
# Bulldozer 1.49(+27%)
# Silvermont 2.88(+13%)
# Knights L 2.12(-) (if system doesn't support AVX)
# Goldmont 1.08(+24%)
# March 2013
#
# ... 8x aggregate factor AVX code path is using reduction algorithm
# suggested by Shay Gueron[1]. Even though contemporary AVX-capable
# CPUs such as Sandy and Ivy Bridge can execute it, the code performs
# sub-optimally in comparison to above mentioned version. But thanks
# to Ilya Albrekht and Max Locktyukhin of Intel Corp. we knew that
# it performs in 0.41 cycles per byte on Haswell processor, in
# 0.29 on Broadwell, and in 0.36 on Skylake.
#
# Knights Landing achieves 1.09 cpb.
