-# This module implements support for Intel AES-NI extension. In
-# OpenSSL context it's used with Intel engine, but can also be used as
-# drop-in replacement for crypto/aes/asm/aes-x86_64.pl [see below for
-# details].

-# Performance.
-#
-# Given aes(enc|dec) instructions' latency asymptotic performance for
-# non-parallelizable modes such as CBC encrypt is 3.75 cycles per byte
-# processed with 128-bit key. And given their throughput asymptotic
-# performance for parallelizable modes is 1.25 cycles per byte. Being
-# asymptotic limit it's not something you commonly achieve in reality,
-# but how close does one get? Below are results collected for
-# different modes and block sized. Pairs of numbers are for en-/
-# decryption.
-#
-# 16-byte 64-byte 256-byte 1-KB 8-KB
-# ECB 4.25/4.25 1.38/1.38 1.28/1.28 1.26/1.26 1.26/1.26
-# CTR 5.42/5.42 1.92/1.92 1.44/1.44 1.28/1.28 1.26/1.26
-# CBC 4.38/4.43 4.15/1.43 4.07/1.32 4.07/1.29 4.06/1.28
-# CCM 5.66/9.42 4.42/5.41 4.16/4.40 4.09/4.15 4.06/4.07
-# OFB 5.42/5.42 4.64/4.64 4.44/4.44 4.39/4.39 4.38/4.38
-# CFB 5.73/5.85 5.56/5.62 5.48/5.56 5.47/5.55 5.47/5.55
-#
-# ECB, CTR, CBC and CCM results are free from EVP overhead. This means
-# that otherwise used 'openssl speed -evp aes-128-??? -engine aesni
-# [-decrypt]' will exhibit 10-15% worse results for smaller blocks.
-# The results were collected with specially crafted speed.c benchmark
-# in order to compare them with results reported in "Intel Advanced
-# Encryption Standard (AES) New Instruction Set" White Paper Revision
-# 3.0 dated May 2010. All above results are consistently better. This
-# module also provides better performance for block sizes smaller than
-# 128 bytes in points *not* represented in the above table.
-#
-# Looking at the results for 8-KB buffer.
-#
-# CFB and OFB results are far from the limit, because implementation
-# uses "generic" CRYPTO_[c|o]fb128_encrypt interfaces relying on
-# single-block aesni_encrypt, which is not the most optimal way to go.
-# CBC encrypt result is unexpectedly high and there is no documented
-# explanation for it. Seemingly there is a small penalty for feeding
-# the result back to AES unit the way it's done in CBC mode. There is
-# nothing one can do and the result appears optimal. CCM result is
-# identical to CBC, because CBC-MAC is essentially CBC encrypt without
-# saving output. CCM CTR "stays invisible," because it's neatly
-# interleaved wih CBC-MAC. This provides ~30% improvement over
-# "straghtforward" CCM implementation with CTR and CBC-MAC performed
-# disjointly. Parallelizable modes practically achieve the theoretical
-# limit.
-#
-# Looking at how results vary with buffer size.
-#
-# Curves are practically saturated at 1-KB buffer size. In most cases
-# "256-byte" performance is >95%, and "64-byte" is ~90% of "8-KB" one.
-# CTR curve doesn't follow this pattern and is "slowest" changing one
-# with "256-byte" result being 87% of "8-KB." This is because overhead
-# in CTR mode is most computationally intensive. Small-block CCM
-# decrypt is slower than encrypt, because first CTR and last CBC-MAC
-# iterations can't be interleaved.
-#
-# Results for 192- and 256-bit keys.
-#
-# EVP-free results were observed to scale perfectly with number of
-# rounds for larger block sizes, i.e. 192-bit result being 10/12 times
-# lower and 256-bit one - 10/14. Well, in CBC encrypt case differences
-# are a tad smaller, because the above mentioned penalty biases all
-# results by same constant value. In similar way function call
-# overhead affects small-block performance, as well as OFB and CFB
-# results. Differences are not large, most common coefficients are
-# 10/11.7 and 10/13.4 (as opposite to 10/12.0 and 10/14.0), but one
-# observe even 10/11.2 and 10/12.4 (CTR, OFB, CFB)...

-#
-# While Westmere processor features 6 cycles latency for aes[enc|dec]
-# instructions, which can be scheduled every second cycle, Sandy
-# Bridge spends 8 cycles per instruction, but it can schedule them
-# every cycle. This means that code targeting Westmere would perform
-# suboptimally on Sandy Bridge. Therefore this update.
-#
-# In addition, non-parallelizable CBC encrypt (as well as CCM) is
-# optimized. Relative improvement might appear modest, 8% on Westmere,
-# but in absolute terms it's 3.77 cycles per byte encrypted with
-# 128-bit key on Westmere, and 5.07 - on Sandy Bridge. These numbers
-# should be compared to asymptotic limits of 3.75 for Westmere and
-# 5.00 for Sandy Bridge. Actually, the fact that they get this close
-# to asymptotic limits is quite amazing. Indeed, the limit is
-# calculated as latency times number of rounds, 10 for 128-bit key,
-# and divided by 16, the number of bytes in block, or in other words
-# it accounts *solely* for aesenc instructions. But there are extra
-# instructions, and numbers so close to the asymptotic limits mean
-# that it's as if it takes as little as *one* additional cycle to
-# execute all of them. How is it possible? It is possible thanks to
-# out-of-order execution logic, which manages to overlap post-
-# processing of previous block, things like saving the output, with
-# actual encryption of current block, as well as pre-processing of
-# current block, things like fetching input and xor-ing it with
-# 0-round element of the key schedule, with actual encryption of
-# previous block. Keep this in mind...
-#
-# For parallelizable modes, such as ECB, CBC decrypt, CTR, higher
-# performance is achieved by interleaving instructions working on
-# independent blocks. In which case asymptotic limit for such modes
-# can be obtained by dividing above mentioned numbers by AES
-# instructions' interleave factor. Westmere can execute at most 3
-# instructions at a time, meaning that optimal interleave factor is 3,
-# and that's where the "magic" number of 1.25 come from. "Optimal
-# interleave factor" means that increase of interleave factor does
-# not improve performance. The formula has proven to reflect reality
-# pretty well on Westmere... Sandy Bridge on the other hand can
-# execute up to 8 AES instructions at a time, so how does varying
-# interleave factor affect the performance? Here is table for ECB
-# (numbers are cycles per byte processed with 128-bit key):
-#
-# instruction interleave factor 3x 6x 8x
-# theoretical asymptotic limit 1.67 0.83 0.625
-# measured performance for 8KB block 1.05 0.86 0.84
-#
-# "as if" interleave factor 4.7x 5.8x 6.0x
-#
-# Further data for other parallelizable modes:
-#
-# CBC decrypt 1.16 0.93 0.93
-# CTR 1.14 0.91 n/a
-#
-# Well, given 3x column it's probably inappropriate to call the limit
-# asymptotic, if it can be surpassed, isn't it? What happens there?
-# Rewind to CBC paragraph for the answer. Yes, out-of-order execution
-# magic is responsible for this. Processor overlaps not only the
-# additional instructions with AES ones, but even AES instuctions
-# processing adjacent triplets of independent blocks. In the 6x case
-# additional instructions still claim disproportionally small amount
-# of additional cycles, but in 8x case number of instructions must be
-# a tad too high for out-of-order logic to cope with, and AES unit
-# remains underutilized... As you can see 8x interleave is hardly
-# justifiable, so there no need to feel bad that 32-bit aesni-x86.pl
-# utilizies 6x interleave because of limited register bank capacity.
-#
-# Higher interleave factors do have negative impact on Westmere
-# performance. While for ECB mode it's negligible ~1.5%, other
-# parallelizables perform ~5% worse, which is outweighed by ~25%
-# improvement on Sandy Bridge. To balance regression on Westmere
-# CTR mode was implemented with 6x aesenc interleave factor.
-
-# April 2011
-#
-# Add aesni_xts_[en|de]crypt. Westmere spends 1.33 cycles processing
-# one byte out of 8KB with 128-bit key, Sandy Bridge - 0.97. Just like
-# in CTR mode AES instruction interleave factor was chosen to be 6x.
