generic_han...x_domain_irq(9)

💅 NAME 💅

generic_handle_demux_domain_irq — okay so this is the girl that goes and invokes the handler for a hardware interrupt of a demultiplexing domain. That's the whole job bestie, that's what she does ✨

Oh and hi, welcome to the Kernel API Manual — you're gonna slay this one, trust 💖

---

🌸 SYNOPSIS 🌸

bool generic_handle_demux_domain_irq (struct irq_domain *domain ,
irq_hw_number_t hwirq );

Like, she takes two things and hands you back a bool. Clean, simple, iconic 👑

---

🎀 ARGUMENTS 🎀

• domain — the domain where to perform the lookup. That's the vibe check zone, the place she's gonna go searching 🔍
• hwirq — the hardware interrupt number to convert to a logical one. Your raw number walks in, a logical one walks out, it's giving glow-up 💅

---

🦋 RETURN 🦋

She gives you True on success. But if the lookup has failed? false, bestie. That's it. That's the whole mood 😭
