πŸ’… irq_domain_set_info(9) πŸ’…

Okay bestie, welcome to the Kernel API Manual β€” yes, the manual name is literally Kernel API Manual, we're in the kernel club now πŸŽ€. This page is about one very specific little function that sets up all the interrupt info for a virtual IRQ, and honestly? It's giving β€œone stop shop” energy ✨.


πŸ’– NAME πŸ’–

irq_domain_set_info β€” literally sets the complete data for a @virq in @domain πŸ’…. That's the whole vibe. No cap.


✨ SYNOPSIS ✨

void irq_domain_set_info (struct irq_domain *domain , unsigned int virq
, irq_hw_number_t hwirq , const struct irq_chip *chip , void *chip_data
, irq_flow_handler_t handler , void *handler_data , const char
*handler_name );

Like, yes, it's a long signature β€” but she's iconic for it πŸ‘‘.


πŸŽ€ ARGUMENTS πŸŽ€

  • domain β€” the interrupt domain to match. Think of it as the group chat this IRQ belongs to 🫢.
  • virq β€” the IRQ number. The virtual one, bestie πŸ’«.
  • hwirq β€” the hardware interrupt number. The original, the real one, the main character πŸ”₯.
  • chip β€” the associated interrupt chip. The hardware bestie that handles the actual work πŸ’….
  • chip_data β€” the associated interrupt chip data. Extra lil’ context for the chip πŸ“.
  • handler β€” the interrupt flow handler. The one who knows the flow, fr fr 🌊.
  • handler_data β€” the interrupt flow handler data. More context for the handler, because she needs her details too 🧚.
  • handler_name β€” the interrupt handler name. Name her, don't leave her unnamed 😭.

That's the whole friend group right there 🌈. Go read them, bestie β€” they all ate πŸ’–.
