  • This adds micro-benchmarks useful for tuning virtio ring layouts.
    Three layouts are currently implemented:

    - virtio 0.9 compatible one
    - an experimental extension bypassing the ring index, polling ring
    itself instead
    - an experimental extension bypassing avail and used ring completely

    Typical use:

    sh run-on-all.sh perf stat -r 10 --log-fd 1 -- ./ring

    It doesn't depend on the kernel directly, but it's handy
    to have as much virtio stuff as possible in one tree.
