drm_atomic_h...async_commit(9)

🎀 NAME 🎀

drm_atomic_helper_async_commit — commit state asynchronously, no cap 💅

okay so this page is drm_atomic_h...async_commit(9) from the Kernel API Manual, and it's literally the async-commit bestie of the DRM atomic helper family. let's get into it ✨

---

✨ SYNOPSIS ✨

void drm_atomic_helper_async_commit (struct drm_device *dev , struct drm_atomic_commit *state );

---

💅 ARGUMENTS 💅

• dev — the DRM device, obvi 🫶
• state — the driver state object, the main-character struct of this whole situation 💖

---

🦋 DESCRIPTION 🦋

This function commits a state asynchronously — meaning it's not vblank synchronized, bestie. not even a little. ⭐

Use it on a state only when drm_atomic_async_check succeeds. fr fr, that's the vibe check you cannot skip. 🙈

Async commits are not supposed to swap the states like normal sync commits do — they just do in-place changes on the current state. that's the whole gig. 💀

TODO, straight from the source: Implement full swap instead of doing in-place changes. 😭
