Log message:
Planting the first seed for OpenBSD/powerpc64.

As support for additional hardware platforms brings opportunities to find (and fix) bugs on other, more established environments, this is definitely an interesting development. Of course it is still currently very much in its infancy, so don't drag out your POWER9 systems just yet, unless you're ready to roll up your sleeves and get some diffs submitted. Thanks to Mark for working on this port!

    Just curious, would this prospective release support the Apple PowerMac G5 architecture?

      I am wondering the same thing.

      Note that there is already support for PowerMac G5 through the macppc port. I have an iMac G5 succesfully running OpenBSD/macppc.

        That's 32-bit mode though, isn't it?
