platform_kernel-5.15/tools/virtio/ringtest/README

Partial implementation of various ring layouts, useful to tune virtio design.
Uses shared memory heavily.

Typical use:

# sh run-on-all.sh perf stat -r 10 --log-fd 1 -- ./ring
tools/virtio: add ringtest utilities 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.
