✨ viortc_class_alarm_irq_enable(9) ✨

okay so this is a page from the Kernel API Manual, section 9 — yes, that section 9, the kernel-functions one 🫶 — and it's all about one tiny little function. don't let the giant name scare you, bestie, it's literally just "turn the alarm interrupt on or off" and honestly? iconic behaviour 💅

🎀 NAME 🎀

viortc_class_alarm_irq_enable — the RTC class op alarm_irq_enable. that's it, that's the whole vibe. it's the class operation that flips the alarm IRQ ✨

---

🌸 SYNOPSIS 🌸

int viortc_class_alarm_irq_enable (struct device *dev , unsigned int
enabled );

like, look at her. gorgeous. takes two things, gives you back an int 💖 (yes, the spacing is exactly like that, i don't make the rules 😭)

🦋 ARGUMENTS 🦋

• dev — the virtio device. this is your main character right here 👑 the virtio device you're doing the thing to.
• enabled — enable or disable the alarm IRQ. that's the whole switch, bestie: on mode or off mode 🌈

⭐ CONTEXT ⭐

Process context. so like, normal-process vibes only. you're not in some weird interrupt place, you're just... in a process, doing your thing 🧚

💜 RETURN 💜

• Zero on success — slay, it worked 💅
• negative error code otherwise — not slay, something went wrong 😭 (negative, so you will notice)
