✨ ledtrig_cpu(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 you're reading the page for ledtrig_cpu, section 9 (that's the kernel API girly section, iykyk 🧚). It's literally about making a CPU pop off a little event so an LED goes blink-blink. iconic behavior, no cap.

🌸 NAME 🌸

ledtrig_cpu — emit a CPU event as a trigger 🎀

like, it's the thing that sends out a CPU event as a trigger. that's the whole vibe fr fr.

---

⭐ SYNOPSIS ⭐

void ledtrig_cpu (enum cpu_led_event ledevt );

yes queen, that's the exact signature, don't come for me 🫶 returns void, takes one enum cpu_led_event named ledevt.

🦋 ARGUMENTS 🦋

• ledevt — the CPU event you wanna emit 💅 that's it, that's the argument. the event goes in, the vibes come out.

---

🔥 DESCRIPTION 🔥

So here's the tea ☕: this function emits a CPU event on a CPU core 💻✨. And because it's a trigger, that event will trigger a bound LED to turn on or turn off 🌈. That's literally it — CPU core does a thing, the LED reacts. main character energy from both of them honestly 👑.

no extra lore, no secret side quests, just emit + trigger + LED does its little on/off moment 💡🫶.
