Not really:-( Itanium2 has 6 -// integer ALU ports, i.e. it's 2 ports wider, but it's not enough to -// spin twice as fast, as I need 8 IALU ports. Amount of floating point -// ports is the same, i.e. 2, while I need 4. In other words, to this -// module Itanium2 remains effectively as "wide" as Itanium. Yet it's -// essentially different in respect to this module, and a re-tune was -// required. Well, because some intruction latencies has changed. Most -// noticeably those intensively used: -// -// Itanium Itanium2 -// ldf8 9 6 L2 hit -// ld8 2 1 L1 hit -// getf 2 5 -// xma[->getf] 7[+1] 4[+0] -// add[->st8] 1[+1] 1[+0] -// -// What does it mean? You might ratiocinate that the original code -// should run just faster... Because sum of latencies is smaller... -// Wrong! Note that getf latency increased. This means that if a loop is -// scheduled for lower latency (as they were), then it will suffer from -// stall condition and the code will therefore turn anti-scalable, e.g. -// original bn_mul_words spun at 5*n or 2.5 times slower than expected -// on Itanium2! What to do? Reschedule loops for Itanium2? But then -// Itanium would exhibit anti-scalability.

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/. -# ==================================================================== - -# On PA-7100LC this module performs ~90-50% better, less for longer -# keys, than code generated by gcc 3.2 for PA-RISC 1.1. Latter means -# that compiler utilized xmpyu instruction to perform 32x32=64-bit -# multiplication, which in turn means that "baseline" performance was -# optimal in respect to instruction set capabilities. Fair comparison -# with vendor compiler is problematic, because OpenSSL doesn't define -# BN_LLONG [presumably] for historical reasons, which drives compiler -# toward 4 times 16x16=32-bit multiplicatons [plus complementary -# shifts and additions] instead. This means that you should observe -# several times improvement over code generated by vendor compiler -# for PA-RISC 1.1, but the "baseline" is far from optimal. The actual -# improvement coefficient was never collected on PA-7100LC, or any -# other 1.1 CPU, because I don't have access to such machine with -# vendor compiler. But to give you a taste, PA-RISC 1.1 code path -# reportedly outperformed code generated by cc +DA1.1 +O3 by factor -# of ~5x on PA-8600. -# -# On PA-RISC 2.0 it has to compete with pa-risc2[W].s, which is -# reportedly ~2x faster than vendor compiler generated code [according -# to comment in pa-risc2[W].s]. Here comes a catch. Execution core of -# this implementation is actually 32-bit one, in the sense that it -# operates on 32-bit values. But pa-risc2[W].s operates on arrays of -# 64-bit BN_LONGs... How do they interoperate then? No problem. This -# module picks halves of 64-bit values in reverse order and pretends -# they were 32-bit BN_LONGs. But can 32-bit core compete with "pure" -# 64-bit code such as pa-risc2[W].s then? Well, the thing is that -# 32x32=64-bit multiplication is the best even PA-RISC 2.0 can do, -# i.e. there is no "wider" multiplication like on most other 64-bit -# platforms. This means that even being effectively 32-bit, this -# implementation performs "64-bit" computational task in same amount -# of arithmetic operations, most notably multiplications. It requires -# more memory references, most notably to tp[num], but this doesn't -# seem to exhaust memory port capacity. And indeed, dedicated PA-RISC -# 2.0 code path provides virtually same performance as pa-risc2[W].s: -# it's ~10% better for shortest key length and ~10% worse for longest -# one. -# -# In case it wasn't clear. The module has two distinct code paths: -# PA-RISC 1.1 and PA-RISC 2.0 ones. Latter features carry-free 64-bit -# additions and 64-bit integer loads, not to mention specific -# instruction scheduling. In 64-bit build naturally only 2.0 code path -# is assembled. In 32-bit application context both code paths are -# assembled, PA-RISC 2.0 CPU is detected at run-time and proper path -# is taken automatically. Also, in 32-bit build the module imposes -# couple of limitations: vector lengths has to be even and vector -# addresses has to be 64-bit aligned. Normally neither is a problem: -# most common key lengths are even and vectors are commonly malloc-ed, -# which ensures alignment. -# -# Special thanks to polarhome.com for providing HP-UX account on -# PA-RISC 1.1 machine, and to correspondent who chose to remain -# anonymous for testing the code on PA-RISC 2.0 machine. - -$0 =~ m/(.*[\/\\])[^\/\\]+$/;

For further -# details see http://www.openssl.org/~appro/cryptogams/. -# ==================================================================== - -# December 2007 - -# The reason for undertaken effort is basically following. Even though -# Power 6 CPU operates at incredible 4.7GHz clock frequency, its PKI -# performance was observed to be less than impressive, essentially as -# fast as 1.8GHz PPC970, or 2.6 times(!) slower than one would hope. -# Well, it's not surprising that IBM had to make some sacrifices to -# boost the clock frequency that much, but no overall improvement? -# Having observed how much difference did switching to FPU make on -# UltraSPARC, playing same stunt on Power 6 appeared appropriate... -# Unfortunately the resulting performance improvement is not as -# impressive, ~30%, and in absolute terms is still very far from what -# one would expect from 4.7GHz CPU. There is a chance that I'm doing -# something wrong, but in the lack of assembler level micro-profiling -# data or at least decent platform guide I can't tell... Or better -# results might be achieved with VMX... Anyway, this module provides -# *worse* performance on other PowerPC implementations, ~40-15% slower -# on PPC970 depending on key length and ~40% slower on Power 5 for all -# key lengths. As it's obviously inappropriate as "best all-round" -# alternative, it has to be complemented with run-time CPU family -# detection. Oh! It should also be noted that unlike other PowerPC -# implementation IALU ppc-mont.pl module performs *suboptimaly* on -# >=1024-bit key lengths on Power 6. It should also be noted that -# *everything* said so far applies to 64-bit builds! As far as 32-bit -# application executed on 64-bit CPU goes, this module is likely to -# become preferred choice, because it's easy to adapt it for such -# case and *is* faster than 32-bit ppc-mont.pl on *all* processors. - -# February 2008 - -# Micro-profiling assisted optimization results in ~15% improvement -# over original ppc64-mont.pl version, or overall ~50% improvement -# over ppc.pl module on Power 6. If compared to ppc-mont.pl on same -# Power 6 CPU, this module is 5-150% faster depending on key length, -# [hereafter] more for longer keys. But if compared to ppc-mont.pl -# on 1.8GHz PPC970, it's only 5-55% faster. Still far from impressive -# in absolute terms, but it's apparently the way Power 6 is... - -# December 2009 - -# Adapted for 32-bit build this module delivers 25-120%, yes, more -# than *twice* for longer keys, performance improvement over 32-bit -# ppc-mont.pl on 1.8GHz PPC970. However! This implementation utilizes -# even 64-bit integer operations and the trouble is that most PPC -# operating systems don't preserve upper halves of general purpose -# registers upon 32-bit signal delivery. They do preserve them upon -# context switch, but not signalling:-( This means that asynchronous -# signals have to be blocked upon entry to this subroutine. Signal -# masking (and of course complementary unmasking) has quite an impact -# on performance, naturally larger for shorter keys. It's so severe -# that 512-bit key performance can be as low as 1/3 of expected one. -# This is why this routine can be engaged for longer key operations -# only on these OSes, see crypto/ppccap.c for further details. MacOS X -# is an exception from this and doesn't require signal masking, and -# that's where above improvement coefficients were collected. For -# others alternative would be to break dependence on upper halves of -# GPRs by sticking to 32-bit integer operations... - -$flavour = shift; - -if ($flavour =~ /32/) { - $SIZE_T=4; - $RZONE= 224;

V8plus achitecture? What kind of beast is that? - * A. Well, it's rather a programming model than an architecture... - * It's actually v9-compliant, i.e. *any* UltraSPARC, CPU under - * special conditions, namely when kernel doesn't preserve upper - * 32 bits of otherwise 64-bit registers during a context switch. - * - * Q. Why just UltraSPARC? What about SuperSPARC? - * A. Original release did target UltraSPARC only. Now SuperSPARC - * version is provided along. Both version share bn_*comba[48] - * implementations (see comment later in code for explanation). - * But what's so special about this UltraSPARC implementation? - * Why didn't I let compiler do the job? Trouble is that most of - * available compilers (well, SC5.0 is the only exception) don't - * attempt to take advantage of UltraSPARC's 64-bitness under - * 32-bit kernels even though it's perfectly possible (see next - * question). - * - * Q. 64-bit registers under 32-bit kernels? Didn't you just say it - * doesn't work? - * A. You can't adress *all* registers as 64-bit wide:-( The catch is - * that you actually may rely upon %o0-%o5 and %g1-%g4 being fully - * preserved if you're in a leaf function, i.e. such never calling - * any other functions. All functions in this module are leaf and - * 10 registers is a handful. And as a matter of fact none-"comba" - * routines don't require even that much and I could even afford to - * not allocate own stack frame for 'em:-) - * - * Q. What about 64-bit kernels? - * A. What about 'em? Just kidding:-) Pure 64-bit version is currently - * under evaluation and development... - * - * Q. What about shared libraries? - * A. What about 'em? Kidding again:-) Code does *not* contain any - * code position dependencies and it's safe to include it into - * shared library as is. - * - * Q. How much faster does it go? - * A.

The reasons -# for undertaken effort are multiple. First of all, UltraSPARC is not -# the whole SPARCv9 universe and other VIS-free implementations deserve -# optimized code as much. Secondly, newly introduced UltraSPARC T1, -# a.k.a. Niagara, has shared FPU and concurrent FPU-intensive pathes, -# such as sparcv9a-mont, will simply sink it. Yes, T1 is equipped with -# several integrated RSA/DSA accelerator circuits accessible through -# kernel driver [only(*)], but having decent user-land software -# implementation is important too. Finally, reasons like desire to -# experiment with dedicated squaring procedure. Yes, this module -# implements one, because it was easiest to draft it in SPARCv9 -# instructions... - -# (*) Engine accessing the driver in question is on my TODO list. -# For reference, acceleator is estimated to give 6 to 10 times -# improvement on single-threaded RSA sign. It should be noted -# that 6-10x improvement coefficient does not actually mean -# something extraordinary in terms of absolute [single-threaded] -# performance, as SPARCv9 instruction set is by all means least -# suitable for high performance crypto among other 64 bit -# platforms. 6-10x factor simply places T1 in same performance -# domain as say AMD64 and IA-64. Improvement of RSA verify don't -# appear impressive at all, but it's the sign operation which is -# far more critical/interesting. - -# You might notice that inner loops are modulo-scheduled:-) This has -# essentially negligible impact on UltraSPARC performance, it's -# Fujitsu SPARC64 V users who should notice and hopefully appreciate -# the advantage... Currently this module surpasses sparcv9a-mont.pl -# by ~20% on UltraSPARC-III and later cores, but recall that sparcv9a -# module still have hidden potential [see TODO list there], which is -# estimated to be larger than 20%... - -# int bn_mul_mont( -$rp="%i0"; # BN_ULONG *rp, -$ap="%i1"; # const BN_ULONG *ap, -$bp="%i2"; # const BN_ULONG *bp, -$np="%i3"; # const BN_ULONG *np, -$n0="%i4"; # const BN_ULONG *n0, -$num="%i5"; # int num); - -$bits=32; -for (@ARGV) { $bits=64 if (/\-m64/ || /\-xarch\=v9/); } -if ($bits==64) { $bias=2047; $frame=192; } -else { $bias=0; $frame=128; } - -$car0="%o0"; -$car1="%o1"; -$car2="%o2"; # 1 bit -$acc0="%o3"; -$acc1="%o4"; -$mask="%g1"; # 32 bits, what a waste... -$tmp0="%g4"; -$tmp1="%g5"; - -$i="%l0"; -$j="%l1"; -$mul0="%l2"; -$mul1="%l3"; -$tp="%l4"; -$apj="%l5"; -$npj="%l6"; -$tpj="%l7"; - -$fname="bn_mul_mont_int"; - -$code=<<___; -.section ".text",#alloc,#execinstr - -.global $fname -.align 32 -$fname: - cmp %o5,4 ! 128 bits minimum - bge,pt %icc,.Lenter - sethi %hi(0xffffffff),$mask - retl - clr %o0 -.align 32 -.Lenter: - save %sp,-$frame,%sp - sll $num,2,$num ! num*=4 - or $mask,%lo(0xffffffff),$mask - ld [$n0],$n0 - cmp $ap,$bp - and $num,$mask,$num - ld [$bp],$mul0 ! bp[0] - nop - - add %sp,$bias,%o7 ! real top of stack - ld [$ap],$car0 ! ap[0] ! redundant in squaring context - sub %o7,$num,%o7 - ld [$ap+4],$apj ! ap[1] - and %o7,-1024,%o7 - ld [$np],$car1 ! np[0] - sub %o7,$bias,%sp ! alloca - ld [$np+4],$npj ! np[1] - be,pt `$bits==32?"%icc":"%xcc"`,.Lbn_sqr_mont - mov 12,$j - - mulx $car0,$mul0,$car0 ! ap[0]*bp[0] - mulx $apj,$mul0,$tmp0 !prologue! ap[1]*bp[0] - and $car0,$mask,$acc0 - add %sp,$bias+$frame,$tp - ld [$ap+8],$apj !prologue! - - mulx $n0,$acc0,$mul1 !

But the rest, whole Sun -# UltraSPARC family and brand new Fujitsu's SPARC64 V, all support -# VIS extension instructions used in this module.

It should also be noted that SPARC64 V features -# out-of-order execution, which *might* mean that integer multiplier -# is pipelined, which in turn *might* be impossible to match... On -# additional note, SPARC64 V implements FP Multiply-Add instruction, -# which is perfectly usable in this context... In other words, as far -# as Fujitsu SPARC64 V goes, talk to the author:-) - -# The implementation implies following "non-natural" limitations on -# input arguments: -# - num may not be less than 4; -# - num has to be even; -# Failure to meet either condition has no fatal effects, simply -# doesn't give any performance gain. - -# TODO: -# - modulo-schedule inner loop for better performance (on in-order -# execution core such as UltraSPARC this shall result in further -# noticeable(!) improvement); -# - dedicated squaring procedure[?]; - -###################################################################### -# November 2006 -# -# Modulo-scheduled inner loops allow to interleave floating point and -# integer instructions and minimize Read-After-Write penalties.
