STRUCT IOMMU_FAULT(9)

💖 struct iommu_fault(9) 💖

okay bestie, so this is a page straight out of the Kernel API Manual and it's about struct iommu_fault(9) — the generic fault data struct, no cap. it's lowkey tiny but she's iconic 🎀

---

✨ NAME ✨

struct iommu_fault — generic fault data. that's it, that's the vibe 🦋

---

🌸 SYNOPSIS 🌸

struct iommu_fault {
    u32 type;
    struct iommu_fault_page_request prm;
};

look at her. two members. main character energy fr 💅

---

👑 MEMBERS 👑

• type — the fault type, and it comes straight from enum iommu_fault_type. literally the vibe check of the whole struct ✨
• prm — the Page Request message, and it only shows up when type is IOMMU_FAULT_PAGE_REQ. so like, conditional member representation, iykyk 🫶

heads up babe: this one's just a struct definition, so there are no options, no exit statuses, and no signals to worry about. we stay safe out here 💅
