💅 drm_kunit_h..._state_alloc(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this page is literally about drm_kunit_helper_atomic_state_alloc, and no, we're not abbreviating it, it's the whole vibe. 🎀

---

✨ NAME ✨

drm_kunit_helper_atomic_state_alloc — Allocates an atomic state 🦋

---

🌸 SYNOPSIS 🌸

struct drm_atomic_commit * drm_kunit_helper_atomic_state_alloc (struct
kunit *test , struct drm_device *drm , struct drm_modeset_acquire_ctx
*ctx );

like, look at that signature. iconic. no notes. 💅

---

🎀 ARGUMENTS 🎀

• test — the test context object, aka the main character of this whole situation 👑
• drm — the device you're allocating the state for 🖥️
• ctx — the locking context for that atomic update 🔒

---

🦋 DESCRIPTION 🦋

So what it does: it allocates an empty atomic state ✨. Empty. Blank slate. fresh start energy. 🫶

and here's the important bit, bestie, pay attention —

the state is tied to the kunit test context, which means you must not call drm_atomic_commit_put on it 😭 it literally gets done automatically. not you. the test context handles it. stay in your lane, it's giving delegation. 💀

---

🔥 RETURN 🔥

• an ERR_PTR on error 🙈
• a pointer to the newly allocated state otherwise — slay ⭐
