📦 version 7.3.1, in nixpkgs unstable

💅 irq_domain_alloc_irqs_parent — NAME ✨

okay so bestie, this is a page from the Kernel API Manual, and the function is irq_domain_alloc_irqs_parent — it allocates interrupts from the parent domain. that's the whole vibe. your domain's parent has the goods, and this function goes and gets 'em 🫶

🌸 SYNOPSIS 🌸

int irq_domain_alloc_irqs_parent (struct irq_domain *domain , unsigned
int irq_base , unsigned int nr_irqs , void *arg );

like, look at her. four params, returns an int, main character energy fr fr 💅

🎀 ARGUMENTS 🎀

  • domain — the domain below which interrupts must be allocated. so she's the one sitting under the parent, and everything gets allocated underneath her. queen of hierarchy 👑
  • irq_base — the base IRQ number. the starting point, the origin story, the place where the numbering begins ✨
  • nr_irqs — number of IRQs to allocate. how many we're grabbing. no cap, you gotta tell her 🙈
  • arg — allocation data, and it's arch/domain specific — meaning it's giving "you know your own architecture best, i don't know her" 💀

🦋 SEE ALSO 🦋

so there's a whole friend group here, and they all live in the kernel file ./kernel/irq/irqdomain.c — go say hi to the gc:

okay that's the whole page bestie, ily, go allocate some interrupts responsibly 🧚💖

this lil cutie lives in ./kernel/irq, and the manual page is dated October 2026 — so jot that down, it's irq_domain_a..._irqs_parent(9), periodt. 💜
