💅 irq_domain_free_irqs_parent — a vibe check

okay so real talk, bestie, we're deep in the Kernel API Manual today and this one is a lil function called irq_domain_free_irqs_parent. It's literally the "give the interrupts back to your parent" moment — the cleanup era, the Marie Kondo of IRQ land 🧹✨

✨ NAME ✨

irq_domain_free_irqs_parent — no cap, this is the one that frees interrupts from the parent domain 💖

🌸 SYNOPSIS 🌸

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

she's void, she takes three things, she returns nothing, and honestly? iconic behavior 👑

🎀 ARGUMENTS 🎀

  • domain — the domain below which the interrupts have to be freed, like the cool older sibling domain that everything hangs off of 🦋
  • irq_base — the base IRQ number, the starting line, the origin story ✨
  • nr_irqs — how many IRQs we're freeing, the headcount, the guest list 💅

🦋 SEE ALSO 🦋

like, everything is connected, iykyk — these are all in the kernel file ./kernel/irq/irqdomain.c and here's the whole squad, no gatekeeping 🔥

that's the whole page bestie, go free those parent-domain interrupts and slay 💜🫶 this lil number lives under ./kernel/irq and the manual's dated October 2026 — see u in the next one, mwah 💋
