drm_crtc_commit_wait(9)

💫 drm_crtc_commit_wait(9) 💫

okay bestie, welcome to the Kernel API Manual 💅 this one's called drm_crtc_commit_wait — a tiny lil function with main character energy. it's a 9-section kernel page, so buckle up 🎀

---

✨ NAME ✨

drm_crtc_commit_wait — literally just waits for a commit to complete. that's it. that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

int drm_crtc_commit_wait (struct drm_crtc_commit *commit );

---

✨ ARGUMENTS ✨

• commit — the drm_crtc_commit you're waiting on. hand it over and let it cook 🍓

---

✨ DESCRIPTION ✨

so the whole point: this function waits for a given drm_crtc_commit to actually get programmed into the hardware and flipped to. like, genuinely waits. no cap. it's the "are we there yet" of atomic commits 😭

---

✨ RETURN ✨

• 0 on success 🎉
• a negative error code otherwise 💀

ngl bestie, if you're calling this from a context where blocking is rude, that's on you — the page just says it waits, and waiting is what it does 🙈

---

that's the whole page, fr fr 💖 it lives over in ./drivers/gpu/drm and this version is dated October 2026. mwah, go wait on that commit, you got this 🌈⭐
