STRUCT DRM_PAGEMAP_IOVA_STATE(9)

✨ NAME ✨

Okay bestie, welcome to the Kernel API Manual page for struct drm_pagemap_iova_state — aka DRM pagemap IOVA state. 💅

That’s the name, that’s the vibe, no cap.

---

🌸 SYNOPSIS 🌸

struct drm_pagemap_iova_state {
    struct dma_iova_state dma_state;
    unsigned long offset;
};

---

💖 Members 💖

• dma_state — DMA IOVA state. Yep, that’s the whole note, periodt.
• offset — Current offset in IOVA. It’s giving “where are we right now” energy. 🎀

---

🦋 DESCRIPTION 🦋

This structure acts as an iterator for packing all IOVA addresses within a contiguous range. That’s literally its whole main-character job: walk the range, pack the IOVAs, slay. ✨

No extra lore, no side quests — it’s an iterator for a contiguous IOVA range, fr fr.
