intel_dp_is_edp(9)

💖 NAME 💖

Okay bestie, meet intel_dp_is_edp from the Kernel API Manual ✨ — it answers the question: is the given port attached to an eDP panel (either CPU or PCH)? 👑

🌸 SYNOPSIS 🌸

bool intel_dp_is_edp (struct intel_dp *intel_dp );

🎀 ARGUMENTS 🎀

• intel_dp — the DP struct 🫶 (that's the one and only argument, no cap).

🦋 DESCRIPTION 🦋

If a CPU or PCH DP output is attached to an eDP panel, this function will return true, and false otherwise. Literally that simple, bestie 💅.

⚠️ Real talk: this function is not safe to use prior to encoder type being set. Do not skip that part, okay? 😭
