vfio_ccw_sch_event(9)

🌸 NAME 🌸

Okay so bestie, this is vfio_ccw_sch_event(9) from the Kernel API Manual — and it's literally here to process subchannel event. That's the whole vibe. 💅

---

✨ SYNOPSIS ✨

int vfio_ccw_sch_event (struct subchannel *sch , int process );

---

🫶 ARGUMENTS 🫶

• sch — the subchannel. Yep, struct subchannel *, no cap. 🦋
• process — non-zero if the function is called in process context. Important detail, bestie, don't skip it. ✨

---

💖 DESCRIPTION 💖

So an unspecified event occurred for this subchannel. Not a specific named event — just an event, okay? 🌈

Adjust data according to the current operational state of the subchannel. That's the assignment. Do it right. 💅

Return zero when the event has been handled sufficiently — or -EAGAIN when this function should be called again in process context. Both outcomes are valid, it's giving "depends on the moment" energy. 👑

Bestie note: -EAGAIN is not a failure vibe here — it literally means "call me again in process context." Periodt. 💖
