[Qemu-devel] [PATCH v2 00/67] target/arm: Scalable Vector Extension


From: Richard Henderson
Subject: [Qemu-devel] [PATCH v2 00/67] target/arm: Scalable Vector Extension
Date: Sat, 17 Feb 2018 10:22:16 -0800

This is 99% of the instruction set.  There are a few things missing,
notably first-fault and non-fault loads (even these are decoded, but
simply treated as normal loads for now).

The patch set is dependant on at least 3 other branches.
A fully composed tree is available as

  git://github.com/rth7680/qemu.git tgt-arm-sve-7

There are a few checkpatch errors due to macros and typedefs, but
nothing that isn't be obvious as a false positive.

This is able to run SVE enabled Himeno and LULESH benchmarks as
compiled by last week's gcc-8:

$ ./aarch64-linux-user/qemu-aarch64 ~/himeno-advsimd
mimax = 129 mjmax = 65 mkmax = 65
imax = 128 jmax = 64 kmax =64
cpu : 67.028643 sec.
Loop executed for 200 times
Gosa : 1.688752e-03 
MFLOPS measured : 49.136295
Score based on MMX Pentium 200MHz : 1.522662

$ ./aarch64-linux-user/qemu-aarch64 ~/himeno-sve 
mimax = 129 mjmax = 65 mkmax = 65
imax = 128 jmax = 64 kmax =64
cpu : 43.481213 sec.
Loop executed for 200 times
Gosa : 3.830036e-06 
MFLOPS measured : 75.746259
Score based on MMX Pentium 200MHz : 2.347266

Hopefully the size of the patch set isn't too daunting...
