STRUCT VDUSE_VQ_STATE(9)

✨ struct vduse_vq_state(9) ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — today's main character is struct vduse_vq_state, and it's literally the virtqueue state. no cap. 💅

---

🌸 NAME 🌸

struct vduse_vq_state — virtqueue state 💖

---

🦋 SYNOPSIS 🦋

struct vduse_vq_state {
    __u32 index;
    union {
      struct vduse_vq_state_split split;
      struct vduse_vq_state_packed packed;
    };
 };

like, that's the whole vibe. copy it exactly, don't touch it, she's perfect already ✨

👑 Members 👑

• index — the virtqueue index 🍓 (which virtqueue we're talking about, iykyk)
• {unnamed_union} — anonymous. that's it. that's the whole description. she has no name and she doesn't need one 🙈
• split — split virtqueue state 🧚 (the split-flavoured state, living inside that anonymous union)
• packed — packed virtqueue state 🔥 (the packed-flavoured one, same union, different vibe)

lowkey important: split and packed are in an anonymous union together, so it's one or the other in there — not both chilling at the same time. 🫶

mwah 💋 that's a wrap! this iconic little page ships from ./include/uapi/linux, dated October 2026, and it's filed under struct vduse_vq_state(9) — periodt. 🫶✨🎀
