intel_hpd_trigger_irq(9)

💖 NAME 💖

okay so bestie, welcome to the intel_hpd_trigger_irq(9) page from the Kernel API Manual — yes, that manual. This one is literally about triggering an hpd irq event for a port. That’s the whole vibe. 👑

✨ SYNOPSIS ✨

void intel_hpd_trigger_irq (struct intel_digital_port *dig_port );

🎀 ARGUMENTS 🎀

• dig_port — digital port. That’s the port in question, and it’s giving main character energy for this call. 🫶

🌸 DESCRIPTION 🌸

So here’s the tea: this function triggers an HPD interrupt event for the given port, emulating a short pulse generated by the sink, and then it schedules the dig port work to handle it. No cap — that’s exactly what it does. 💅

bestie, this isn’t some vague “do something with the port” situation; it’s specifically an HPD interrupt event, specifically emulating the sink’s short pulse, and specifically scheduling the dig port work to handle it. The details are the moment. ✨
