💅 drm_atomic_b...chain_enable(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie — buckle up 🎀

🌸 NAME 🌸

drm_atomic_bridge_chain_enable — literally turns on every single bridge in the encoder chain 💖

✨ SYNOPSIS ✨

void drm_atomic_bridge_chain_enable (struct drm_bridge *first_bridge ,
struct drm_atomic_commit *state );

🫶 ARGUMENTS 🫶

• first_bridge — the bridge control structure, aka your starting point, your main character 🦋
• state — the atomic state that's being committed rn, no cap ✨

🔥 DESCRIPTION 🔥

So what it does: it calls the drm_bridge_funcs.atomic_enable op for all the bridges in the encoder chain — starting from the first bridge and going all the way to the last, in order, periodt 💅

And the timing? These get called after drm_encoder_helper_funcs.atomic_enable finishes. Like, sequence matters, iykyk ⭐

💀 NOTE 💀

the bridge you pass in should be the one closest to the encoder — not me stressing about this, but like, actually do this 🙈
