STRUCT IOMMU_DESTROY(9)

💅 NAME 💅

okay so welcome to the Kernel API Manual, bestie — today’s main character is struct iommu_destroy(9), and its NAME vibe is literally:

struct iommu_destroy - ioctl(IOMMU_DESTROY)

that’s it, that’s the name, slay 💖

---

✨ SYNOPSIS ✨

here’s the exact struct, no edits, no cap:

struct iommu_destroy {
    __u32 size;
    __u32 id;
 };

---

🧚 Members 🧚

• size — sizeof(struct iommu_destroy) — literally the size of this struct, periodt 💅
• id — the iommufd object ID to destroy. Can be any destroyable object type. 🦋

---

🦋 Description 🦋

okay so the actual job is tiny but powerful: Destroy any object held within iommufd. That’s the whole description. It’s giving “bye bestie” energy to any object held within iommufd, and honestly? iconic. 💅✨

mwah 💋 — this page comes from the ./include/uapi/linux source/version, dated October 2026, and it’s still struct iommu_destroy(9) at the end. 🫶✨
