💅 intel_dpt_suspend — bestie's guide to suspending DPT FB memory mappings ✨

okay so like, this is the intel_dpt_suspend(9) manpage from the Kernel API Manual and honestly it's giving "short but crucial" energy 🎀

🌸 NAME 🌸

intel_dpt_suspend — suspend the memory mapping for all DPT FBs during system suspend 💤

like literally, when the system goes night-night, this is the function that handles the DPT framebuffer memory mapping situation 🦋

---

✨ SYNOPSIS ✨

void intel_dpt_suspend (struct intel_display *display );

no cap, that's the whole signature 💅

---

🎀 ARGUMENTS 🎀

• display — display device instance 🖥️✨ (the main character of this whole operation, fr fr)

💖 DESCRIPTION 💖

okay so here's the tea ☕ — this function suspends the memory mapping during system suspend for all framebuffers that are mapped to HW via a GGTT->DPT page table 🔥

⚠️ important bestie alert ⚠️ — this function must be called before the mappings in GGTT are suspended by calling i915_ggtt_suspend. like, order matters here, no cap. don't do it the other way around or it's giving chaos 💀

and that's the whole vibe! 💜

this iconic little page lives in ./drivers/gpu/drm/i915/display and was dated October 2026 — so mark your calendars bestie, the future called and it's all about DPT suspend 🫶✨🍓
