💅 drm_bridge_hpd_disable(9) 💅

Kernel API Manual energy, but make it group-chat 💖

---

🌸 NAME 🌸

drm_bridge_hpd_disable — disable hot plug detection for the bridge 🎀

---

✨ SYNOPSIS ✨

void drm_bridge_hpd_disable (struct drm_bridge *bridge );

---

🎀 ARGUMENTS 🎀

• bridge — the bridge control structure 🎛️

---

🦋 DESCRIPTION 🦋

Okay so bestie, this is the “turn the hot plug detection callback off” function 💅 It calls drm_bridge_funcs.hpd_disable if that's implemented, and it unregisters the hot plug detection callback that was previously registered with drm_bridge_hpd_enable. Clean, simple, iconic ✨

Once this function returns, the callback will not be called by the bridge when an output status change occurs. So like… the callback is officially off the group chat 🫶

Hot plug detection is supported only if the DRM_BRIDGE_OP_HPD flag is set in bridge->ops.

This function shall not be called when the flag is not set. That's not a vibe, that's a rule 💀 Please respect it.
