vme_irq_generate(9)

✨ vme_irq_generate(9) ✨

okay so bestie, welcome to the vme_irq_generate page of the Kernel API Manual — this is the one where we make a VME interrupt happen on purpose 💅 literally manifesting an interrupt into existence, no cap.

---

🌸 NAME 🌸

vme_irq_generate — generate a VME interrupt 🎀

---

🦋 SYNOPSIS 🦋

int vme_irq_generate (struct vme_dev *vdev , int level , int statid );

---

✨ ARGUMENTS ✨

• vdev — a pointer to the VME device struct vme_dev that's been assigned to your driver instance 🫶 like, this is your device, the one you were given, don't go grabbing somebody else's.
• level — the interrupt priority at which to assert the interrupt 🔥 highkey important: this is the priority, so pick it with intention.
• statid — the interrupt vector to associate with the interrupt ⭐ this is the vector, matching up with the interrupt you're firing off.

---

💖 DESCRIPTION 💖

Generate a VME interrupt of the provided level and with the provided statid 💀 that's it, that's the whole thing.

So you hand it a level, you hand it a statid, and it asserts a VME interrupt with exactly those. iconic behavior honestly 👑 it's giving "one job, done well."

---

🌈 RETURN 🌈

• Zero on success — slay, it worked 🎉
• -EINVAL if you passed an invalid vme device, an invalid level, or if the function is not supported 🚩

also: hardware specific errors are possible too 😭 so like, don't come for this function if the hardware itself is being weird — sometimes it's not the code, it's the vibes of the silicon.
