intel_frontbuffer_flip(9)

💅 intel_frontbuffer_flip(9) — Kernel API Manual, but make it make sense

okay bestie, welcome to the Kernel API Manual entry for intel_frontbuffer_flip(9) — yes that whole title is the header, we're not copying it twice, we're better than that 🎀

---

✨ NAME ✨

intel_frontbuffer_flip — a synchronous frontbuffer flip, no cap 🫶

---

🌸 SYNOPSIS 🌸

void intel_frontbuffer_flip (struct intel_display *display , unsigned
frontbuffer_bits );

literally that's the whole signature, she's petite 💅

---

🦋 ARGUMENTS 🦋

• display — the display device 💖 like, the actual thing you're poking at
• frontbuffer_bits — the frontbuffer plane tracking bits ✨ these are the little flags that say which planes we're keeping tabs on

---

🔥 DESCRIPTION 🔥

okay so here's the vibe: this function gets called after scheduling a flip on obj 📌 say it with me — after scheduling, not during, not before, after 💀

it's built for synchronous plane updates — the kind that will happen on the next vblank and which will not get delayed by pending gpu rendering ⭐ that's the whole point, no waiting around for the gpu to finish its thing, it goes off on the next vblank periodt 👑

and the best part?? it can be called without any locks held 🙈 no lock anxiety, no "wait do i hold the mutex", none of that — she's chill like that 🧚

---

💜 SEE ALSO 💜

• Kernel file ./drivers/gpu/drm/i915/display/intel_frontbuffer.c — the source, go read her 📖
• frontbuffer tracking(9)
• frontbuffer_flush(9)
• intel_frontbuffer_queue_flush(9)
• intel_frontbuffer_track(9)

like a little friend group of frontbuffer functions, iykyk 🌈

ngl if you're flipping frontbuffers synchronously and you skipped the vblank part, go back and reread the description bestie, it's all there 😭

and that's the page!! cute sign-off time 🎀 this beauty lives in ./drivers/gpu/drm/i915/display, dated October 2026, and yeah her name is still intel_frontbuffer_flip(9) — iconic, no notes 💖✨🦋
