STRUCT TI_SCI_INTA_VINT_DESC(9)

📦 version 7.3.1, in nixpkgs unstable

💖 struct ti_sci_inta_vint_desc(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, that's the actual manual name, and yes, we're getting into it. today's main character is struct ti_sci_inta_vint_desc, and it's literally the description of a virtual interrupt coming out of the Interrupt Aggregator. that's the whole vibe. 🎀

✨ NAME ✨

struct ti_sci_inta_vint_desc — the description of a virtual interrupt coming out of the Interrupt Aggregator. no cap, that's what it is. 🦋

🌸 SYNOPSIS 🌸

like, here's the whole shape of her:

struct ti_sci_inta_vint_desc {
    struct irq_domain *domain;
    struct list_head list;
    unsigned long event_map[BITS_TO_LONGS( MAX_EVENTS_PER_VINT)];
    struct ti_sci_inta_event_desc events[MAX_EVENTS_PER_VINT];
    unsigned int parent_virq;
    u16 vint_id;
 };

copy that exactly, don't be out here retyping it from memory bestie 😭

💅 Members 💅

she's got six fields and every single one is important, so let's do a little lineup, okay?

  • domain — pointer to the IRQ domain that this vint belongs to. like, her home base. 🏠
  • list — the list entry for the vint list. she's on a list. iconic behaviour. 📋
  • event_map — a bitmap used to manage the allocation of events to the vint. it's the little allocator brain. 🧠
  • events — an array of event descriptors that are assigned to this vint. the whole squad. 👯
  • parent_virq — the Linux IRQ number that gets attached to the parent. 🫶
  • vint_id — the TISCI vint ID. that's it, that's the field. 🔥
ngl, this is a struct in the kernel, so please treat her fields with respect — they're not just cute names, they're Real Data. 💀

🌈 SEE ALSO 🌈

the kernel file to go peek at: ./drivers/irqchip/irq-ti-sci-inta.c — and then the whole friend group:

okay that's the whole page, bestie, you ate that 🫶 and a lil sign-off for the credits: this one lives in ./drivers/irqchip, dated October 2026, and it's the struct ti_sc...ta_vint_desc(9) page from the Kernel API Manual. periodt. 👑✨
