tools/virtio: add ringtest utilities

2016-01-26T08:18:30Z

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.

tools/virtio: fix byteswap logic

2015-12-07T15:28:10Z

commit cf561f0d2eb74574ad9985a2feab134267a9d298 ("virtio: introduce virtio_is_little_endian() helper") changed byteswap logic to skip feature bit checks for LE platforms, but didn't update tools/virtio, so vring_bench started failing. Update the copy under tools/virtio/ (TODO: find a way to avoid this code duplication). Cc: Greg Kurz Signed-off-by: Michael S. Tsirkin
