ENUM IOMMU_VEVENTQ_TYPE(9)

✨ enum iommu_veventq_type(9) ✨

okay so bestie, this is a page straight out of the Kernel API Manual, section 9, and it's literally just a little enum that tells the kernel which flavor of virtual event queue you're talking about 🎀 it's giving "small but mighty", honestly.

---

💖 NAME 💖

enum iommu_veventq_type — Virtual Event Queue Type 🌸

Like yeah it's giving "just a type", but it's the type that tells everyone whose event queue we're vibing with 💅

---

🦋 SYNOPSIS 🦋

enum iommu_veventq_type {
    IOMMU_VEVENTQ_TYPE_DEFAULT ,
    IOMMU_VEVENTQ_TYPE_ARM_SMMUV3 ,
    IOMMU_VEVENTQ_TYPE_TEGRA241_CMDQV

};

three constants, no cap. that's the whole squad 💜

---

👑 Constants 👑

okay here's the lineup, one by one, no skipping, we don't do that here:

• IOMMU_VEVENTQ_TYPE_DEFAULT — Reserved for future use 🫶 like it's literally just sitting there holding a seat for someone who hasn't shown up yet. iconic placeholder behavior.
• IOMMU_VEVENTQ_TYPE_ARM_SMMUV3 — ARM SMMUv3 Virtual Event Queue ⭐ that's your ARM SMMUv3 vibes.
• IOMMU_VEVENTQ_TYPE_TEGRA241_CMDQV — NVIDIA Tegra241 CMDQV Extension IRQ 🔥 yes, Tegra241, yes CMDQV, yes the extension IRQ.

that's it. three. all accounted for. periodt 💅

ngl bestie, you don't have to read all of those right now. but they're there. iykyk 💀

and that's the whole page!! sign-off time: this lil masterpiece lives in ./include/uapi/linux, dated October 2026 🎀 go forth and queue your virtual events, queen 👑💖
