drm_atomic_h...e_pre_enable(9)

okay so bestie 💖 welcome to the Kernel API Manual page for drm_atomic_helper_commit_encoder_bridge_pre_enable(9) — the header shortens it to drm_atomic_h...e_pre_enable(9), and honestly fair 💀. This one is giving “bridge chain pre-enable era” and we’re gonna get into it ✨

💅 NAME 💅

drm_atomic_helper_commit_encoder_bridge_pre_enable — pre-enable bridges 🌉💖

✨ SYNOPSIS ✨

void drm_atomic_helper_commit_encoder_bridge_pre_enable (struct
       drm_device *dev , struct drm_atomic_commit *state );

🎀 ARGUMENTS 🎀

• dev — DRM device 🖥️
• state — atomic state object being committed ✨

🦋 DESCRIPTION 🦋

Okay so the tea ☕: this function loops over the connectors 🔁 and, if the CRTC needs it, pre-enables the entire bridge chain 🌉💖. That’s literally the whole plot. No cap.

🌈 SEE ALSO 🌈
