vme_irq_request(9)

🌸 NAME 🌸

okay so bestie, welcome to the vme_irq_request(9) page from the Kernel API Manual 💖

vme_irq_request — Request a specific VME interrupt. 💅

---

✨ SYNOPSIS ✨

lowkey here's the exact signature, no cap:

       int vme_irq_request (struct vme_dev *vdev , int level , int statid ,
       void (*callback)(int level, int statid, void *priv_data) , void
       *priv_data );

---

🎀 ARGUMENTS 🎀

• vdev — Pointer to VME device struct vme_dev assigned to driver instance. like, this is your device's whole identity bestie 🫶
• level — Interrupt priority being requested. the priority vibe check ⭐
• statid — Interrupt vector being requested. the vector in question, periodt 🎀
• callback — Pointer to callback function called when VME interrupt/vector received. this is the function that gets pinged when the interrupt/vector shows up 📞
• priv_data — Generic pointer that will be passed to the callback function. your lil extra data package, hand-delivered to the callback 🍓

---

💅 DESCRIPTION 💅

Request callback to be attached as a handler for VME interrupts with provided level and statid.

so the whole vibe is: you're asking for your callback to be attached as the handler for VME interrupts that match the level and statid you gave. it's giving "put me on the interrupt guest list" ✨

---

🫶 RETURN 🫶

• 0 — Zero on success. slay, it worked 💖
• -EINVAL — on invalid vme device, level or if the function is not supported. not it 😭
• -EBUSY — if the level/statid combination is already in use. occupied, bestie, try another combo 💀
• Hardware specific errors also possible. yeah, hardware can absolutely do its own thing 🙈
