ENUM IOMMU_VEVENTQ_FLAG(9)

💅 enum iommu_veventq_flag(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ this is the page for enum iommu_veventq_flag — yes that's a whole mouthful, we're doing it, stay with me 🫶

---

🌸 NAME 🌸

enum iommu_veventq_flag — literally just the flag for struct iommufd_vevent_header, no cap 💖

---

✨ SYNOPSIS ✨

enum iommu_veventq_flag {
    IOMMU_VEVENTQ_FLAG_LOST_EVENTS

};

look at her. one (1) member. main character energy 👑

---

🎀 Constants 🎀

• IOMMU_VEVENTQ_FLAG_LOST_EVENTS — the vEVENTQ has lost vEVENTs 😭 that's it, that's the whole vibe. events went missing. gone. not me crying about dropped vEVENTs 💀

---

🦋 SEE ALSO 🦋

okay this list is long long, but every single one of these is iconic in her own way, so here we go, no skipping, i promised 🫶

that's sixty-one entries and yes i counted, we don't do half measures here 💅🔥

also heads up: this page lives under ./include/uapi/linux and it's dated October 2026, so like… future vibes 🌈

and that's the whole page bestie, you ate that 🍓 stay hydrated, read your headers, and remember: if IOMMU_VEVENTQ_FLAG_LOST_EVENTS is set, the vEVENTQ has lost vEVENTs and you should probably go look at that 🙈💜
