✨ drm_atomic_helper_bridge_duplicate_state(9) ✨

okay bestie, so this is a page from the Kernel API Manual and it's literally all about one lil helper: drm_atomic_helper_bridge_duplicate_state. it's giving "small function, big responsibilities" and honestly? iconic. 🎀

💖 NAME 💖

drm_atomic_helper_bridge_duplicate_state — Duplicate a bridge state object 🦋

🌸 SYNOPSIS 🌸

struct drm_bridge_state * drm_atomic_helper_bridge_duplicate_state
(struct drm_bridge *bridge );

like, that's the whole vibe. one function, one pointer in, one shiny state pointer out. slay. ✨

🎀 ARGUMENTS 🎀

  • bridge — the bridge object. that's it. that's the whole argument. she's low maintenance, we love her 💅

🔥 DESCRIPTION 🔥

so what does she actually do? bestie, she allocates a brand new bridge state and initializes it with the current bridge state values. no cap — fresh object, copied values, done. 🫶

this helper is meant to be used as a bridge drm_bridge_funcs.atomic_duplicate_state hook, specifically for bridges that don't subclass the bridge state. so if your bridge is out here living a simple un-subclassed life, this is the hook for you. periodt. 👑
