crypto: arm/sha512 - accelerated SHA-512 using ARM generic ASM and NEON
This replaces the SHA-512 NEON module with the faster and more versatile implementation from the OpenSSL project. It consists of both a NEON and a generic ASM version of the core SHA-512 transform, where the NEON version reverts to the ASM version when invoked in non-process context. This patch is based on the OpenSSL upstream version b1a5d1c65208 of sha512-armv4.pl, which can be found here: https://git.openssl.org/gitweb/?p=openssl.git;h=b1a5d1c65208 Performance relative to the generic implementation (measured using tcrypt.ko mode=306 sec=1 running on a Cortex-A57 under KVM): input size block size asm neon old neon 16 16 1.39 2.54 2.21 64 16 1.32 2.33 2.09 64 64 1.38 2.53 2.19 256 16 1.31 2.28 2.06 256 64 1.38 2.54 2.25 256 256 1.40 2.77 2.39 1024 16 1.29 2.22 2.01 1024 256 1.40 2.82 2.45 1024 1024 1.41 2.93 2.53 2048 16 1.33 2.21 2.00 2048 256 1.40 2.84 2.46 2048 1024 1.41 2.96 2.55 2048 2048 1.41 2.98 2.56 4096 16 1.34 2.20 1.99 4096 256 1.40 2.84 2.46 4096 1024 1.41 2.97 2.56 4096 4096 1.41 3.01 2.58 8192 16 1.34 2.19 1.99 8192 256 1.40 2.85 2.47 8192 1024 1.41 2.98 2.56 8192 4096 1.41 2.71 2.59 8192 8192 1.51 3.51 2.69 Acked-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

+# SHA512 block procedure for ARMv4. September 2007.
+
+# This code is ~4.5 (four and a half) times faster than code generated
+# by gcc 3.4 and it spends ~72 clock cycles per byte [on single-issue
+# Xscale PXA250 core].
+#
+# July 2010.
+#
+# Rescheduling for dual-issue pipeline resulted in 6% improvement on
+# Cortex A8 core and ~40 cycles per processed byte.
+
+# February 2011.
+#
+# Profiler-assisted and platform-specific optimization resulted in 7%
+# improvement on Coxtex A8 core and ~38 cycles per byte.
+
+# March 2011.
+#
+# Add NEON implementation. On Cortex A8 it was measured to process
+# one byte in 23.3 cycles or ~60% faster than integer-only code.
+
+# August 2012.
+#
+# Improve NEON performance by 12% on Snapdragon S4. In absolute
+# terms it's 22.6 cycles per byte, which is disappointing result.
+# Technical writers asserted that 3-way S4 pipeline can sustain
+# multiple NEON instructions per cycle, but dual NEON issue could
+# not be observed, see http://www.openssl.org/~appro/Snapdragon-S4.html
+# for further details. On side note Cortex-A15 processes one byte in
+# 16 cycles.
+
+# Byte order [in]dependence. =========================================
+#
+# Originally caller was expected to maintain specific *dword* order in
+# h[0-7], namely with most significant dword at *lower* address, which
+# was reflected in below two parameters as 0 and 4. Now caller is
+# expected to maintain native byte order for whole 64-bit values.

+@ ====================================================================
+@ 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/.
+@
+@ Permission to use under GPL terms is granted.
+@ ====================================================================
+
+@ SHA512 block procedure for ARMv4. September 2007.
+
+@ This code is ~4.5 (four and a half) times faster than code generated
+@ by gcc 3.4 and it spends ~72 clock cycles per byte [on single-issue
+@ Xscale PXA250 core].
+@
+@ July 2010.
+@
+@ Rescheduling for dual-issue pipeline resulted in 6% improvement on
+@ Cortex A8 core and ~40 cycles per processed byte.
+
+@ February 2011.
+@
+@ Profiler-assisted and platform-specific optimization resulted in 7%
+@ improvement on Coxtex A8 core and ~38 cycles per byte.
+
+@ March 2011.
+@
+@ Add NEON implementation. On Cortex A8 it was measured to process
+@ one byte in 23.3 cycles or ~60% faster than integer-only code.
+
+@ August 2012.
+@
+@ Improve NEON performance by 12% on Snapdragon S4. In absolute
+@ terms it's 22.6 cycles per byte, which is disappointing result.
+@ Technical writers asserted that 3-way S4 pipeline can sustain
+@ multiple NEON instructions per cycle, but dual NEON issue could
+@ not be observed, see http://www.openssl.org/~appro/Snapdragon-S4.html
+@ for further details. On side note Cortex-A15 processes one byte in
+@ 16 cycles.
+
+@ Byte order [in]dependence. =========================================
+@
+@ Originally caller was expected to maintain specific *dword* order in
+@ h[0-7], namely with most significant dword at *lower* address, which
+@ was reflected in below two parameters as 0 and 4. Now caller is
+@ expected to maintain native byte order for whole 64-bit values.
