✨ devm_drm_dp_hpd_bridge_alloc(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one's a lil function called devm_drm_dp_hpd_bridge_alloc, and it's literally the moment a HPD DisplayPort bridge gets born. 🎀 buckle up, it's short and it slays.

🌸 NAME 🌸

devm_drm_dp_hpd_bridge_alloc — allocate a HPD DisplayPort bridge 💅

---

🦋 SYNOPSIS 🦋

struct auxiliary_device * devm_drm_dp_hpd_bridge_alloc (struct device
*parent , struct device_node *np );

---

✨ ARGUMENTS ✨

• parent — the device instance that's providing this bridge 🫶 like, this is the one doing the giving
• np — the device node pointer that corresponds to this bridge instance 🧚 the lil pointer bestie that matches this bridge

---

💖 DESCRIPTION 💖

so what this does is create a simple DRM bridge, and it sets the type to DRM_MODE_CONNECTOR_DisplayPort — no cap, that's the whole vibe. this bridge is main character energy in the chain because it terminates the bridge chain and it's the one that's able to send the HPD events. 👑

---

🔥 RETURN 🔥

it gives you back a bridge auxiliary device pointer, or an error pointer — so like, always check it, bestie, IS_ERR() is your friend 🙈
