✨ xudc_irq(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for xudc_irq — yes we're doing kernel interrupt handlers today and yes it's giving main character energy 💅. Pull up a chair, this one's short but it's important.

🌸 NAME 🌸

xudc_irq — the main interrupt handler. that's it, that's the whole vibe. she handles interrupts. she's the main one. periodt 💖

🦋 SYNOPSIS 🦋

irqreturn_t xudc_irq (int irq , void *_udc );

look at her go ✨ two args, returns an irqreturn_t, no cap.

🎀 ARGUMENTS 🎀

  • irq — the interrupt number. literally just the number of the interrupt that fired, that's her whole job here 🫶
  • _udc — a pointer to the usb device controller structure. yes it's a void * and yes you're gonna cast it, iykyk 🙈

💜 RETURN 💜

returns IRQ_HANDLED after the interrupt is handled 👑

like, once she's done handling it. that's the whole return story. handled = handled, fr fr.
