drm_atomic_get_bridge_state(9)

💖 drm_atomic_get_bridge_state(9) 💖

okay so this is the Kernel API Manual, bestie, and we're folding that manual name right in near the top because we're not doing boring repeated headers today. This page is all about drm_atomic_get_bridge_state, and it's lowkey iconic. 💅✨

🌸 NAME 🌸

drm_atomic_get_bridge_state — get bridge state. that's the whole name bit, short and slay. 🎀

📜 SYNOPSIS 📜

struct drm_bridge_state * drm_atomic_get_bridge_state (struct
drm_atomic_commit *state , struct drm_bridge *bridge );

🫶 ARGUMENTS 🫶

• state — global atomic state object. 💫
• bridge — bridge to get state object for. 🎀

🔮 DESCRIPTION 🔮

okay so here's the tea: this function returns the bridge state for the given bridge, and it will allocate that state if needed. It also grabs the relevant bridge lock to make sure that the state is consistent. lock behavior is giving responsible main character energy, fr fr. 🔒✨

🌀 RETURN 🌀

Either the allocated state or the error code encoded into the pointer. When the error is EDEADLK, then the w/w mutex code has detected a deadlock and the entire atomic sequence must be restarted. no cap, that's a whole restart moment 😭🔥
