intel_gvt_f...tracked_mmio(9)

💅 intel_gvt_for_each_tracked_mmio — a kernel API manual moment 🎀

okay so bestie, we're in the Kernel API Manual today and the entry is intel_gvt_f...tracked_mmio(9) — yes the title is abbreviated with the little dots, that's just how the header rolls, don't come for me. The actual function name is the full one below, iykyk. ✨

🌸 NAME 🌸

intel_gvt_for_each_tracked_mmio — iterate each tracked mmio. that's it, that's the vibe. literally a loop-de-loop over your tracked mmio. 🌀

---

✨ SYNOPSIS ✨

int intel_gvt_for_each_tracked_mmio (struct intel_gvt *gvt , int
(*handler)(struct intel_gvt *gvt, u32 offset, void *data) , void *data
);

no cap, that's the whole signature — three args, one function pointer in the middle doing main character energy. 👑

---

🦋 ARGUMENTS 🦋

• gvt — a GVT device. that's your whole little graphics-virtualization situation, hand it over. 🖥️
• handler — the handler. yes that's the entire description in the original and honestly? iconic minimalism. it's the callback, bestie, the thing that runs per-mmio. 💅
• data — private data given to handler. your lil bag of snacks passed along to the callback so it has context. 🍓

---

⭐ RETURN ⭐

Zero on success, negative error code if failed. that's it. 0 = slay, negative = not slay, go check your error code. 😭

lowkey reminder bestie: this is kernel graphics virtualization land, so keep the exact names and exact types — no renaming, no "fixing", the compiler does not care about your aesthetic. 💀

mwah, that's the page! this little number lives under ./drivers/gpu/drm/i915/gvt, dated October 2026, and it's filed as intel_gvt_f...tracked_mmio(9) — same abbreviated title as the top, we love a full-circle moment. take care of her, she's iconic. 🎀🧚💜
