drm_atomic_commit_init(9)

✨ drm_atomic_commit_init(9) ✨

okay so bestie, welcome to the drm_atomic_commit_init page from the Kernel API Manual — yes we're in kernel land today and honestly it's giving main character energy 🔥

---

🌸 SYNOPSIS 🌸

int drm_atomic_commit_init (struct drm_device *dev , struct
       drm_atomic_commit *state );

like, that's the whole vibe: it returns an int, it takes a struct drm_device * and a struct drm_atomic_commit *, and that's it 💅

---

🎀 ARGUMENTS 🎀

• dev — the DRM device, aka the whole entire display situation you're working with 🖥️
• state — the atomic state, the thing being filled in, the star of the show ⭐

---

💖 DESCRIPTION 💖

So this is the default implementation for filling in a new atomic state. Like, it's the out-of-the-box way to set up a fresh state, no cap.

⚠️ real talk though: this should only be used by drivers which are still subclassing drm_atomic_commit and haven't switched to drm_private_state yet. if you're on the new stuff, this is not your moment bestie 🙈
