notify_remote_via_irq(9)

🎀 NAME 🎀

okay so bestie, this is notify_remote_via_irq(9) from the Kernel API Manual 🫶 — the whole vibe is: send event to remote end of event channel via irq ✨ like, that's the function's entire main-character job 💅

🌸 SYNOPSIS 🌸

void notify_remote_via_irq (int irq );

🦋 ARGUMENTS 🦋

• irq — irq of event channel to send event to 💌 so yeah, that's the event channel irq getting the event, no cap.

✨ DESCRIPTION ✨

So unlike notify_remote_via_evtchn, this one is safe to use across save/restore 🎀 periodt. And if the connection is broken? Notifications on a broken connection are silently dropped 😭 — they just get dropped silently, zero dramatic noise. Ngl, that's the whole tea. 🍓
