STRUCT VDUSE_IOVA_RANGE_V2(9)

💖 struct vduse_iova_range_v2(9) — from the Kernel API Manual, bestie 💖

okay so picture this: you're poking around the kernel API manual and this little struct pops up. her whole job? describing an IOVA range — like [start, last] — but specifically when API_VERSION >= 1. that's the vibe check. older versions, she's not your girl. 🎀

struct vduse_iova_range_v2 — the IOVA range [start, last] if API_VERSION >= 1. that's it, that's the whole personality 🫶

🌸 SYNOPSIS 🌸

look at her. iconic. four fields, zero drama:

struct vduse_iova_range_v2 {
    __u64 start;
    __u64 last;
    __u32 asid;
    __u32 padding;
};

🦋 Members 🦋

• start — where the IOVA range starts, like the opening scene of your fave show ✨
