ne_event_handler(9)

💅 ne_event_handler(9) — Kernel API Manual energy

okay so bestie, welcome to ne_event_handler — it's a section 9 kernel API page and it's giving "tiny function, big job" ✨

🌸 NAME 🌸

ne_event_handler — the interrupt handler for out-of-band events coming from a PCI device 🎀

The tea: this interrupt does not supply any data in the MMIO region. Nope, zero payload, nothing to read. What it actually does is notify a change in the state of any of the launched enclaves. That's it, that's the whole vibe check 👑

✨ SYNOPSIS ✨

irqreturn_t ne_event_handler (int irq , void *args );

🦋 ARGUMENTS 🦋

• irq — the received interrupt for an out-of-band event 🔥
• args — the PCI device private data structure, aka where the good stuff lives 🫶

💜 CONTEXT 💜

Interrupt context. Periodt — you're in interrupt context, act accordingly 😭

⭐ RETURN ⭐

• IRQ_HANDLED — returned on handled interrupt ✅
