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.

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...

This -# results in *further* 20-50% perfromance improvement [depending on -# key length, more for longer keys] on USI&II cores and 30-80% - on -# USIII&IV. - -$fname="bn_mul_mont_fpu"; -$bits=32; -for (@ARGV) { $bits=64 if (/\-m64/ || /\-xarch\=v9/); } - -if ($bits==64) { - $bias=2047; - $frame=192; -} else { - $bias=0; - $frame=128; # 96 rounded up to largest known cache-line -} -$locals=64; - -# In order to provide for 32-/64-bit ABI duality, I keep integers wider -# than 32 bit in %g1-%g4 and %o0-%o5. %l0-%l7 and %i0-%i5 are used -# exclusively for pointers, indexes and other small values... -# 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); - -$tp="%l0"; # t[num] -$ap_l="%l1"; # a[num],n[num] are smashed to 32-bit words and saved -$ap_h="%l2"; # to these four vectors as double-precision FP values. -$np_l="%l3"; # This way a bunch of fxtods are eliminated in second -$np_h="%l4"; # loop and L1-cache aliasing is minimized... -$i="%l5"; -$j="%l6"; -$mask="%l7"; # 16-bit mask, 0xffff - -$n0="%g4"; # reassigned(!) to "64-bit" register -$carry="%i4"; # %i4 reused(!) for a carry bit - -# FP register naming chart -# -# ..HILO -# dcba -# -------- -# LOa -# LOb -# LOc -# LOd -# HIa -# HIb -# HIc -# HId -# ..a -# ..b -$ba="%f0"; $bb="%f2"; $bc="%f4"; $bd="%f6"; -$na="%f8"; $nb="%f10"; $nc="%f12"; $nd="%f14"; -$alo="%f16"; $alo_="%f17"; $ahi="%f18"; $ahi_="%f19"; -$nlo="%f20"; $nlo_="%f21"; $nhi="%f22"; $nhi_="%f23"; - -$dota="%f24"; $dotb="%f26"; - -$aloa="%f32"; $alob="%f34"; $aloc="%f36"; $alod="%f38"; -$ahia="%f40"; $ahib="%f42"; $ahic="%f44"; $ahid="%f46"; -$nloa="%f48"; $nlob="%f50"; $nloc="%f52"; $nlod="%f54"; -$nhia="%f56"; $nhib="%f58"; $nhic="%f60"; $nhid="%f62"; - -$ASI_FL16_P=0xD2; # magic ASI value to engage 16-bit FP load - -$code=<<___; -.section ".text",#alloc,#execinstr - -.global $fname -.align 32 -$fname: - save %sp,-$frame-$locals,%sp - - cmp $num,4 - bl,a,pn %icc,.Lret - clr %i0 - andcc $num,1,%g0 ! $num has to be even... - bnz,a,pn %icc,.Lret - clr %i0 ! signal "unsupported input value" - - srl $num,1,$num - sethi %hi(0xffff),$mask - ld [%i4+0],$n0 ! $n0 reassigned, remember? - or $mask,%lo(0xffff),$mask - ld [%i4+4],%o0 - sllx %o0,32,%o0 - or %o0,$n0,$n0 ! $n0=n0[1].n0[0] - - sll $num,3,$num ! num*=8 - - add %sp,$bias,%o0 ! real top of stack - sll $num,2,%o1 - add %o1,$num,%o1 ! %o1=num*5 - sub %o0,%o1,%o0 - and %o0,-2048,%o0 ! optimize TLB utilization - sub %o0,$bias,%sp ! alloca(5*num*8) - - rd %asi,%o7 ! save %asi - add %sp,$bias+$frame+$locals,$tp - add $tp,$num,$ap_l - add $ap_l,$num,$ap_l !
