ibmvmc_handle_event(9)

💅 NAME 💅

ibmvmc_handle_event — okay so this is the interrupt handler for crq events, bestie. That's the whole vibe.

✨ SYNOPSIS ✨

irqreturn_t ibmvmc_handle_event (int irq , void *dev_instance );

🎀 ARGUMENTS 🎀

• irq — the number of the irq you're handling. And like… it's not used. At all. Lowkey just there for the vibes, bestie 🙈
• dev_instance — the crq_server_adapter that received the interrupt. That's the main character right there 👑

🌸 DESCRIPTION 🌸

So what it does is: it disables interrupts and then schedules ibmvmc_task. That's it, that's the whole personality ✨

And it always returns IRQ_HANDLED. No cap, no exceptions, always. Periodt 💅
