💅 VIO9P(4) — Kernel Interfaces Manual edition 💅

okay so bestie, this is the vio9p page from the Kernel Interfaces Manual, and it's literally the VirtIO 9p front-end driver's whole moment. let's get into it 🫶✨

✨ NAME ✨

vio9p — the VirtIO 9p front-end driver. that's the name, no cap 💖

---

🦋 SYNOPSIS 🦋

vio9p* at virtio?

that's it. that's the synopsis. short and iconic 💅

---

🌸 DESCRIPTION 🌸

so when you team it up with mount_9p(8), the vio9p driver enables a NetBSD system running as a VM guest to mount an exported file system by the host via virtio-9p. it's giving bridge-to-the-host energy 🫶

it exports a 9p end-point of virtio-9p via a character device file for mount_9p(8). yes bestie, that's the whole job ✨

each exported file system is assigned a character device and accessible via /dev/vio9p0, /dev/vio9p1 and so on, respectively, in exporting order by the host. so the order the host exports them in is the order you get the devices — slay 🌈

---

🎀 FILES 🎀

• /dev/vio9p? — the device file path pattern, bestie 💖

---

🔥 EXAMPLES 🔥

the following command mounts the first exported file system by the host at /mnt/9p:

# mount_9p -cu /dev/vio9p0 /mnt/9p

ate. no notes. 💅🔥
