There are some addtional instructions apart from bare armv8,
also there is armv8.1, armv8.2.

Most the processor would support crc, except X-gene 1.</pre>

    We have had these tune files sent by other folks in the past. Does
    this settle all the questions from back then ?<br>
    <br>
    <pre>It was sent couple months ago, you can find the discussion in various
threads, e.g.:
<a href="http://lists.openembedded.org/pipermail/openembedded-core/2015-October/111318.html">http://lists.openembedded.org/pipermail/openembedded-core/2015-October/111318.html</a>
