STRUCT IOMMU_SVA(9)

🦋 struct iommu_sva(9) 🦋

okay so bestie, welcome to the Kernel API Manual page for struct iommu_sva — it's giving "handle to a device-mm bond" and honestly? iconic. 💅

---

✨ NAME ✨

struct iommu_sva — handle to a device-mm bond 💖

Like, that's the whole name. Short, sweet, slays.

---

✨ SYNOPSIS ✨

struct iommu_sva {
    struct iommu_attach_handle      handle;
    struct device                   *dev;
    refcount_t users;
 };

lowkey just three fields and a dream, no cap. 🎀

---

✨ Members ✨

so the manpage sets up a whole Members section and then… leaves it empty 😭 not a single line of description. fr fr, this is what the original gives us — no member descriptions, none. So here's what we do know, straight from the struct itself and nothing more:

• handle — of type struct iommu_attach_handle
• dev — a struct device *
• users — a refcount_t

that's it, that's the section. the descriptions are a mystery for the ages 👑 (we don't invent lore here, iykyk.)
