DRM_CAP_ATOM...NC_PAGE_FLIP(9)

💖 DRM_CAP_ATOM...NC_PAGE_FLIP(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes this is the kernel docs, yes it's a whole vibe, and yes the title got truncated in the terminal like a text message that got cut off at the worst possible moment 💀 (it's DRM_CAP_ATOM...NC_PAGE_FLIP(9), that's just how it renders, we move)

---

✨ NAME ✨

DRM_CAP_ATOMIC_ASYNC_PAGE_FLIP

and that's it. that's the whole name section. no little dash-description after it, no nothing — the manpage literally just hits you with the constant and dips 🫶 so we're keeping it exactly like that, no cap.

---

🌸 SYNOPSIS 🌸

DRM_CAP_ATOMIC_ASYNC_PAGE_FLIP

just the one line, standing there, looking iconic 👑

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — if this thing is set to 1, then the driver supports DRM_MODE_PAGE_FLIP_ASYNC for atomic commits. that's the whole flex. that's the entire personality. one sentence, and it ate 💅

so like: value 1 = yes bestie, async page flips are a thing here. anything else and, well, the manpage didn't say, and i'm not about to make stuff up 🙈

like, 42 references plus a file path?? she's booked and busy 😭🔥 read them, they're all part of the lore.

real talk though — literally every name above is copied character-for-character from the page, so if you're grepping for one of these, it's in there, untouched, slaying in its original spelling 💜

and that's the page!! mwah 🫶 before you go: the source line down at the bottom was ./tools/perf/trace/beauty/incl... (yes, also truncated, we love a consistent aesthetic 💀) and it was dated October 2026, with DRM_CAP_ATOM...NC_PAGE_FLIP(9) chilling on the right side. that's the footer, that's the sign-off, go forth and flip some pages asynchronously bestie 🌈⭐
