Looking for Ryzen owners to test SHA acceleration.

Ryzen CPUs have HW accelerated SHA, something Intel's mainstream CPUs won't have until Cannonlake.

Requirements:
  Ryzen CPU
  Linux
  Compiler version with support for sha
  Openssl development package with support for sha
  Cpuminer-opt source code with support for sha

I can provide the last one. GCC is supposed to have support for -msha starting in v 5, and Openssl added support in 2014
so both should be available in Ubuntu 16.04.

The following algos use sha256 and should benefit from HW acceleration: sha256t, lbry, skein, myr-groestl, m7m.

Intel J3455 ASRock J3455M with 1866 memory dual channel
--benchmark results

lbry         Total: 5287.13 kH, 1341.57 kH/s, 43C
sha256t      Total: 4643.44 kH, 6343.56 kH/s, 42C
skein         Total: 15.05 MH, 3223.62 kH/s, 45C
myr-groestl   Total: 7336.60 kH, 1480.04 kH/s, 44C
m7m         Total: 254.99 kH, 38.28 kH/s, 45C

Thanks but that CPU doesn't have HW SHA. This information is displayed
when the program starts.

Compiling is still the biggest challenge to using SHA. Few Linux distros include openssl 1.1 which added SHA support.

It looks like HW SHA to me? This is only a 10w CPU.
