💅 drm_bridge_g...urrent_state(9) — Kernel API Manual, bestie

okay so welcome to the group chat, this is the page for drm_bridge_get_current_state — it lives in the Kernel API Manual and honestly? it's a short one. a little snack. a lil bite-sized baddie. let's get into it 🎀

---

✨ NAME ✨

drm_bridge_get_current_state — get the current bridge state, that's it, that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

struct drm_bridge_state * drm_bridge_get_current_state (struct
drm_bridge *bridge );

like, you hand it a bridge, it hands you back a struct drm_bridge_state *. iconic behavior fr fr 👑

---

💖 ARGUMENTS 💖

• bridge — the bridge object. that's the one. the main character of this function call 🫶

---

⭐ DESCRIPTION ⭐

okay so listen close because this is the important part, no cap:

This function must be called with the modeset lock held. 💀

like literally must. not "should", not "probably fine", must. hold the modeset lock, bestie. do not come in here unlocked, that's not the vibe.

and then what do you get? The current bridge state — or NULL if there is none. that's it. sometimes there's a state, sometimes there's not, and the function is very chill about both 😌✨
