+# ====================================================================
+# Written by Andy Polyakov <appro@openssl.org> for the OpenSSL
+# project. The module is, however, dual licensed under OpenSSL and
+# CRYPTOGAMS licenses depending on where you obtain it. For further
+# details see http://www.openssl.org/~appro/cryptogams/.
+# ====================================================================
+#
+# This module implements support for AES instructions as per PowerISA
+# specification version 2.07, first implemented by POWER8 processor.
+# The module is endian-agnostic in sense that it supports both big-
+# and little-endian cases. Data alignment in parallelizable modes is
+# handled with VSX loads and stores, which implies MSR.VSX flag being
+# set. It should also be noted that ISA specification doesn't prohibit
+# alignment exceptions for these instructions on page boundaries.
+# Initially alignment was handled in pure AltiVec/VMX way [when data
+# is aligned programmatically, which in turn guarantees exception-
+# free execution], but it turned to hamper performance when vcipher
+# instructions are interleaved. It's reckoned that eventual
+# misalignment penalties at page boundaries are in average lower
+# than additional overhead in pure AltiVec approach.

+# CBC encrypt/decrypt performance in cycles per byte processed with
+# 128-bit key.

+# G4e 35.5/52.1/(23.8) 11.9(*)/15.4

+# POWER7 32.3/42.9/(18.4) 18.5/23.3
+#
+# (*) This is ~10% worse than reported in paper. The reason is
+# twofold. This module doesn't make any assumption about
+# key schedule (or data for that matter) alignment and handles
+# it in-line. Secondly it, being transliterated from
+# vpaes-x86_64.pl, relies on "nested inversion" better suited
+# for Intel CPUs.
+# (**) Inadequate POWER6 performance is due to astronomic AltiVec
+# latency, 9 cycles per simple logical operation.

+# ====================================================================
+# Written by Andy Polyakov <appro@openssl.org> for the OpenSSL
+# project. The module is, however, dual licensed under OpenSSL and
+# CRYPTOGAMS licenses depending on where you obtain it. For further
+# details see http://www.openssl.org/~appro/cryptogams/.
+# ====================================================================
+
+# SHA256/512 for PowerISA v2.07.
+#
+# Accurate performance measurements are problematic, because it's
+# always virtualized setup with possibly throttled processor.
+# Relative comparison is therefore more informative. This module is
+# ~60% faster than integer-only sha512-ppc.pl. To anchor to something
+# else, SHA256 is 24% slower than sha1-ppc.pl and 2.5x slower than
+# hardware-assisted aes-128-cbc encrypt. SHA512 is 20% faster than
+# sha1-ppc.pl and 1.6x slower than aes-128-cbc. Another interesting
+# result is degree of computational resources' utilization. POWER8 is
+# "massively multi-threaded chip" and difference between single- and
+# maximum multi-process benchmark results tells that utlization is
+# whooping 94%. For sha512-ppc.pl we get [not unimpressive] 84% and
+# for sha1-ppc.pl - 73%. 100% means that multi-process result equals
+# to single-process one, given that all threads end up on the same
+# physical core.
