Sorry about the walls of text earlier — those were LLM-assisted and I shouldn't have posted them that way.

Just following up on the comment above. It looks like any issue with running was fixed by getting the latest snapshot, and doesn’t look like it was any issue with virtiofs — the driver runs fine on current main.

Hi Emil, I've been pondering this a bit in the last few weeks, trying to learn a bit as I'm going along, and as is probably fairly obvious, with the help of a LLM. I feel like I've made a bit of progress:

Thanks Emil — this is what I was looking for. I just built from the virtiofs branch and got the full stack compiling on main: fusefs.ko, the vtfs transport, and virtiofs.ko all build cleanly. The only needed fix is SRCS+= vnode_if.h in sys/modules/virtiofs/Makefile, so the standalone module build emits the generated header before compiling virtiofs_vfsops.c.

Hi Emil — thanks for this, I'm keen to get virtio-fs working on FreeBSD!! Anything I can do to help, please let me know!
