Just a few minor comments. Note though that I only have time to do a brief review of this and haven't read the relevant section of the spec.

Nit: M_WAITOK means this cannot fail. May be slightly clearer to use mallocarray() instead.

514

A virtqueue_poll() variant with a timeout param could be useful in general.

Thanks for the review @bryanv.
Regarding:

"A virtqueue_poll() variant with a timeout param could be useful in general."

I was thinking exactly the same while doing this, but being a first time contributor to freeBSD, I was not sure how easily acceptable would have been to post a change related to some core system (like virtio) inside this series,
so I went for a custom solution at first. I can certainly post subsequently a patch to add a virtqueue_poll timeout variant to the virtio-core and make use of it in here, once this is merged/landed.

Sure, a separate follow on commit is fine.

Removed needless checks on malloc, using mallocarray

Using mallocarray() and dropping the retval check since invoked as M_WAITOK

I'm a bit late to the party, but is there a reason why this module wasn't hooked into the build system?

see https://cgit.freebsd.org/src/tree/sys/modules/virtio/Makefile
and for example, https://cgit.freebsd.org/src/tree/sys/modules/virtio/network/Makefile

andrew added a comment.Apr 18 2024, 12:27 PM

It's not very useful as a module as it provides infrastructure other devices need, e.g. their clock, or a reset line. If it was a module these drivers would fail to attach if they were built into the kernel.
