💅 drm_atomic_...bridge_state(9) — Kernel API Manual 💅

okay bestie, welcome to the drm_atomic_...bridge_state(9) page. This one lives in the Kernel API Manual, and it is lowkey tiny — but every single detail is coming with us. ✨

💖 NAME 💖

drm_atomic_get_old_bridge_state — get old bridge state, if it exists

🌸 SYNOPSIS 🌸

struct drm_bridge_state * drm_atomic_get_old_bridge_state (const struct
       drm_atomic_commit *state , struct drm_bridge *bridge );

🎀 ARGUMENTS 🎀

• state — the global atomic state object, bestie.
• bridge — the bridge to grab.

🦋 DESCRIPTION 🦋

This function returns the old bridge state for the given bridge, or NULL if the bridge is not part of the global atomic state. That's it — short and iconic. 💅
