STRUCT TI_SCI_RM_IRQ_OPS(9)

💅 struct ti_sci_rm_irq_ops(9) 💅

okay bestie, this is a page from the Kernel API Manual and it's literally all about struct ti_sci_rm_irq_ops — the IRQ management operations struct. yes, the whole thing. let's get into it 🫶

---

✨ NAME ✨

struct ti_sci_rm_irq_ops — IRQ management operations

like... the operations. for managing IRQs. it's giving "the plug for your interrupts" energy 💅

---

🌸 SYNOPSIS 🌸

here's the whole struct, no cap, every function pointer exactly as it lives:

struct ti_sci_rm_irq_ops {
    int (*set_irq)(const struct ti_sci_handle *handle, u16 src_id, u16
src_index, u16 dst_id, u16 dst_host_irq);
    int (*set_event_map)(const struct ti_sci_handle *handle, u16 src_id,
u16 src_index, u16 ia_id, u16 vint, u16 global_event, u8
vint_status_bit);
    int (*free_irq)(const struct ti_sci_handle *handle, u16 src_id, u16
src_index, u16 dst_id, u16 dst_host_irq);
    int (*free_event_map)(const struct ti_sci_handle *handle, u16
src_id, u16 src_index, u16 ia_id, u16 vint, u16 global_event, u8
vint_status_bit);
 };

four function pointers, all returning int, all taking const struct ti_sci_handle *handle first because obviously the handle is the main character ✨

🎀 Members 🎀

okay so here's the cast, one by one:

• set_irq — Set an IRQ route between the requested source and destination. that's it, that's the vibe: source ➡️ destination, route established 🔥
• set_event_map — Set an Event based peripheral irq to Interrupt Aggregator. event-based peripheral irq, meet the Interrupt Aggregator. you're gonna be mapped together 💖
• free_irq — Free an IRQ route between the requested source and destination. yes with the period, it's very final about it 💀 the route? gone. released. bye bestie 👋
• free_event_map — Free an event based peripheral irq to Interrupt Aggregator. also with a period. also very final. the event map gets freed, no notes 🙈
