|
||
+# ====================================================================
|
||
+# 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.

+# 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.
