      tools/virtio: add ringtest utilities · 481eaec3
      Michael S. Tsirkin authored
      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.
