STRUCT IRQ_DOMAIN_CHIP_GENERIC_INFO(9)

✨ NAME ✨

okay bestie, meet struct irq_domain_chip_generic_info — the Generic chip information structure 💅. this is straight from the Kernel API Manual, section 9, and it’s giving “blueprint for your generic interrupt chip info” energy ✨.

✨ SYNOPSIS ✨

here’s the struct in all its iconic glory, no cap — every field exactly as it appears:

       struct irq_domain_chip_generic_info {
           const char              *name;
           irq_flow_handler_t handler;
           unsigned int            irqs_per_chip;
           unsigned int            num_ct;
           unsigned int            irq_flags_to_clear;
           unsigned int            irq_flags_to_set;
           enum irq_gc_flags       gc_flags;
           int (*init)(struct irq_chip_generic *gc);
           void (*exit)(struct irq_chip_generic *gc);
        };

🎀 Members 🎀

okay, member-by-member vibe check, bestie:

• name — Name of the generic interrupt chip 🫶
• handler — Interrupt handler used by the generic interrupt chip ✨
• irqs_per_chip — Number of interrupts each chip handles (max 32) 🔥
• num_ct — Number of irq_chip_type instances associated with each chip 💅
• irq_flags_to_clear — IRQ_* bits to clear in the mapping function 🌸
• irq_flags_to_set — IRQ_* bits to set in the mapping function 🌈
• gc_flags — Generic chip specific setup flags 🎀
• init — function pointer int (*init)(struct irq_chip_generic *gc); Function called on each chip when they are created. Allow to do some additional chip initialisation. ✨
• exit — function pointer void (*exit)(struct irq_chip_generic *gc); Function called on each chip when they are destroyed. Allow to do some chip cleanup operation. 🧚
