    >Why would an x64-native MorphOS need to run on "a software based hypersvisor on a X64 system"?

    Because I use VM boxes to run multiple OS'.

    >using QEMU's mac99 virtualization with KVM-PR, that is.

    Or other virtualizations. I'd like to see something emulating a P5040 based X5000.

    >Why not run this potential little-endian PPC64 version of MorphOS on bare metal (PowerNV) instead of boxed?

    Everything on Power4-9 runs with the hypervisor enabled, even if its only running a single thread.

    >> we could even devote a few threads to emulating X64 [...],
    >> for simultaneous Power and X64 threads via the hypervisor

    >I'm not sure the hypervisor can help with emulating x64 on POWER.

    Niether am I, I haven't had the time to study it well enough, but what little I have covered gives me the impression it will be the core of ourability to run X64 and PPC code concurrently.

    >>no doubt OS4 as well as all we would need would be P50X0 emulation

    >OS4 already runs fine on QEMU's Sam460 emulation. Btw, QEMU already has P50X0/e5500 emulation but that >isn't enough to run OS4 as there's more to a board/system than just the CPU.

    Frankly, I not that concerned as to what the emulated system is, I'd just like to beable to freak out OS4 fanatics by being able to run their OS as part of the type of system I've described.

    >> or better yet e6500 core emulation

    >OS4 doesn't run on e6500.

    No, but MorphOS could, and Linux does.

    >> PCIe slots that are four generations ahead of Tabor

    >3 generations.

    Correct, PCIe v1.0 vs v4.0, so not four generations, but only three. However, if the specs I have are correct, PCIe v1.0 has a transfer rate of 250MB/sec vs PCIe v4.0's transfer rate of 1969MB/sec.
    Or about eight times the bandwidth per lane, with Tabor (and Samantha) only supplying 4 PCIe lanes to the video card while Blackbird's expansion slots provide 8 or 16 lanes.
    In other words, a potential of almost 16 times the bandwidth.

    Yes, this step would be relatively simple.

    So the facility is there if we hook into it? Cool!

    To me, this looks like the superior platform, not X64.
