irq_domain_deactivate_irq(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, this is irq_domain_deactivate_irq(9) straight outta the Kernel API Manual ✨. It’s the “ok we’re done here” move for an interrupt, and the recursive part is literally in the name, so yeah — main character energy. 💅

💖 NAME 💖

irq_domain_deactivate_irq — call domain_ops->deactivate recursively to deactivate interrupt. periodt. 🫶

🌸 SYNOPSIS 🌸

void irq_domain_deactivate_irq (struct irq_data *irq_data );

🎀 ARGUMENTS 🎀

  • irq_data — the outermost irq_data associated with interrupt. That’s the one you’re passing in, bestie. 🦋

✨ DESCRIPTION ✨

It calls domain_ops->deactivate to program interrupt controllers to disable interrupt delivery. That’s the whole plot: the controllers get programmed to stop delivering that interrupt. No cap. 🔥
