crypto: vmx - Add support for VMS instructions by ASM
OpenSSL implements optimized ASM algorithms which support VMX instructions on Power 8 CPU. These scripts generate an endian-agnostic ASM implementation in order to support both big and little-endian. - aesp8-ppc.pl: implements suport for AES instructions implemented by POWER8 processor. - ghashp8-ppc.pl: implements support for GHASH for Power8. - ppc-xlate.pl: ppc assembler distiller. These code has been adopted from OpenSSL project in collaboration with the original author (Andy Polyakov <appro@openssl.org>). Signed-off-by: Leonidas S. Barbosa <leosilva@linux.vnet.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2#
3# ====================================================================
4# Written by Andy Polyakov <appro@openssl.org> for the OpenSSL
5# project. The module is, however, dual licensed under OpenSSL and
6# CRYPTOGAMS licenses depending on where you obtain it. For further
7# details see http://www.openssl.org/~appro/cryptogams/.
8# ====================================================================
9#
10# This module implements support for AES instructions as per PowerISA
11# specification version 2.07, first implemented by POWER8 processor.
12# The module is endian-agnostic in sense that it supports both big-
13# and little-endian cases. Data alignment in parallelizable modes is
14# handled with VSX loads and stores, which implies MSR.VSX flag being
15# set. It should also be noted that ISA specification doesn't prohibit
16# alignment exceptions for these instructions on page boundaries.
17# Initially alignment was handled in pure AltiVec/VMX way [when data
18# is aligned programmatically, which in turn guarantees exception-
19# free execution], but it turned to hamper performance when vcipher
20# instructions are interleaved. It's reckoned that eventual
21# misalignment penalties at page boundaries are in average lower
22# than additional overhead in pure AltiVec approach.

14# Accurate performance measurements are problematic, because it's
15# always virtualized setup with possibly throttled processor.
16# Relative comparison is therefore more informative. This initial
17# version is ~2.1x slower than hardware-assisted AES-128-CTR, ~12x
18# faster than "4-bit" integer-only compiler-generated 64-bit code.
19# "Initial version" means that there is room for futher improvement.
