irq_domain_pop_irq(9)

📦 version 7.3.1, in nixpkgs unstable

💜 irq_domain_pop_irq(9) — the kernel API manual, bestie edition 💜

Okay so picture this: you're deep in the kernel API manual (section 9, obviously), and you need to undo a hierarchy push. That's this function. It's giving cleanup era. Let's go. ✨

🌸 NAME 🌸

irq_domain_pop_irq — remove a domain from the top of a hierarchy, no cap.

🎀 SYNOPSIS 🎀

int irq_domain_pop_irq (struct irq_domain *domain , int virq );

🦋 ARGUMENTS 🦋

  • domain — the domain you're removing. Like, the one getting popped off the top. Bye bestie 💅
  • virq — the irq you're removing the domain from. That's the one losing its top layer.

✨ DESCRIPTION ✨

So this is literally the undo button for a call to irq_domain_push_irq. Push it, pop it, balance restored, the universe is healing. 🌈

Important vibe check: you must call this either before request_irq or after free_irq. Not in between, not mid-flight, not "whenever feels right." Timing is everything, iykyk. ⏰
