💖 struct vic_device(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ — today's main character is struct vic_device, aka the VIC PM device. yes it's a struct, yes it's important, and yes we're gonna get through it together 🫶

🌸 NAME 🌸

struct vic_device — the VIC PM device. that's it, that's the vibe. lowkey iconic naming ngl 💅

✨ SYNOPSIS ✨

struct vic_device {
    void __iomem    *base;
    int irq;
    u32 valid_sources;
    u32 resume_sources;
    u32 resume_irqs;
    u32 int_select;
    u32 int_enable;
    u32 soft_int;
    u32 protect;
    struct irq_domain *domain;
 };

like, look at her. ten fields. flawless. no notes 🔥

🎀 Members 🎀

okay so here's the cast, one by one, no skips, no cuts 💖

  • base — the register base for the VIC. the home address, the whole foundation of the operation fr fr.
  • irq — the IRQ number for the base of the VIC. every queen needs her number, and this is hers.
  • valid_sources — a bitmask of valid interrupts. the guest list, basically — if you're not on it, you're not getting in 🙈
  • resume_sources — a bitmask of interrupts for resume. the "we'll be right back" list, curated with care ⭐
  • resume_irqs — the IRQs enabled for resume. yes bestie, not the same thing as resume_sources, we do not conflate them, we've been over this 😭
  • int_select — save for VIC_INT_SELECT. it's a save slot. she's holding the value down for later 💅
  • int_enable — save for VIC_INT_ENABLE. another save slot, another icon 👑
  • soft_int — save for VIC_INT_SOFT. the soft interrupt's little safety deposit box 🎀
  • protect — save for VIC_PROTECT. protection detail stays protected, periodt.
  • domain — the IRQ domain for the VIC. the whole neighborhood, the whole community, the whole kingdom honestly 🌈

four functions, all slay, all worth your time 🫶

ngl this whole page lives in ./drivers/irqchip, and it's dated October 2026. so yes, technically this is a future bestie sending you love from the irqchip directory 💜 stay hydrated, read your source files, and remember: the VIC is not like other girls 💅✨

bye bestie!! 🦋💖🎀
