💅 NAME 💅

Bestie, welcome to irq_domain_get_irq_data(9) — yes, this is that page, and it lives in the Kernel API Manual. ✨ The whole serve is: get the irq_data associated with @virq and @domain. That's the assignment. Iconic.

unsigned int virq );

🎀 ARGUMENTS 🎀

• domain — the domain to match. 🎯
• virq — the IRQ number to get irq_data for. 🔢
