DRM_PRIME_CAP_EXPORT(9)

💅 DRM_PRIME_CAP_EXPORT(9) ✨

okay bestie, welcome to the Kernel API Manual — yes the whole manual, we're in it, and this little page is the main character today 🎀

---

🌸 NAME 🌸

DRM_PRIME_CAP_EXPORT — literally just the name, no fancy subtitle, the manpage is serving minimalism 💅

---

✨ SYNOPSIS ✨

DRM_PRIME_CAP_EXPORT

that's it. that's the whole synopsis. icon behavior honestly 👑

---

🦋 DESCRIPTION 🦋

okay so here's the tea 🍓 — this is a bit, and if this bit is set in DRM_CAP_PRIME, then the driver supports exporting PRIME buffers via the DRM_IOCTL_PRIME_HANDLE_TO_FD ioctl. no cap, that's the whole vibe check. 🔥

and starting from kernel version 6.6, this bit is always set in DRM_CAP_PRIME — so like, it's giving "always on, never off" energy 💀✨

💀 reminder that if you're skimming, the whole point is the DRM_IOCTL_PRIME_HANDLE_TO_FD ioctl and that 6.6 "always set" glow-up. everything else is supporting cast 🧚

and that's the page!! mwah 💖 this one was brought to you by ./tools/perf/trace/beauty/incl... (yes, the footer really does truncate it like that, we don't make the rules 🙈) dated October 2026, and the title card is DRM_PRIME_CAP_EXPORT(9) — read it, love it, cite it in your bug report, slay 🌈⭐👑
