ENUM IOMMU_HWPT_PGFAULT_FLAGS(9)

💅 enum iommu_hwpt_pgfault_flags — Kernel API Manual ✨

okay so bestie, this is the page for enum iommu_hwpt_pgfault_flags from the Kernel API Manual, and it's literally just two little enum constants that tell you stuff about a page fault. tiny page, big vibes. let's get into it 🫶

---

🌸 NAME 🌸

enum iommu_hwpt_pgfault_flags — the flags that go with struct iommu_hwpt_pgfault, no cap 💅

---

✨ SYNOPSIS ✨

here's the whole enum, exactly as it lives, both members and nothing else:

enum iommu_hwpt_pgfault_flags {
    IOMMU_PGFAULT_FLAGS_PASID_VALID ,
    IOMMU_PGFAULT_FLAGS_LAST_PAGE
};

look at her. two flags. immaculate. 🎀

---

🦋 Constants 🦋

• IOMMU_PGFAULT_FLAGS_PASID_VALID — this one's saying the pasid field inside the fault data is valid, so you can actually trust it. it's giving "yes bestie, that field is real" 💖
• IOMMU_PGFAULT_FLAGS_LAST_PAGE — and this one means it's the last fault of a fault group. like the final text in the group chat, the group is done after this one 🫡

---

👑 SEE ALSO 👑

the kernel file this all lives in is ./include/uapi/linux/iommufd.h, and honestly the whole iommufd friend group shows up in here, so let's do the roll call 🌈

ngl this page is short but she ate. go read struct iommu_hwpt_pgfault(9) next if you wanna see where these flags actually get used 🍓

and that's the whole thing! this page lives at ./include/uapi/linux, dated October 2026, and it's enum iommu_...gfault_flags(9) — mwah, see you in the next one 😭💖🧚
