💖 pvr_device_irq_init(9) — the Kernel API Manual moment 💖

okay so bestie, welcome to the Kernel API Manual page for pvr_device_irq_init(9) — yes the whole thing is literally about getting the IRQ situation sorted for a PowerVR device, and it's lowkey iconic. let's get into it 🎀

---

✨ NAME ✨

pvr_device_irq_init — Initialise IRQ required by a PowerVR device 🌸

like, it sets up the interrupt request stuff that a PowerVR device needs. that's the vibe. periodt.

---

🦋 SYNOPSIS 🦋

int pvr_device_irq_init (struct pvr_device *pvr_dev );

copy it exactly, bestie, don't be cute with it 💅

---

🍓 ARGUMENTS 🍓

• pvr_dev — Target PowerVR device. that's the one you're pointing at, the main character of this function call 👑

---

🔥 RETURN 🔥

so here's what you get back, and there are three possible moods:

• 0 on success — slay, it worked ✨
• Any error returned by platform_get_irq_byname — so if that call fumbles, you're getting its error, no cap 😭
• Any error returned by request_irq — same deal, that call's error comes straight back to you 💀

ngl bestie, the error handling here is essentially "whatever those two functions said, that's the answer." no extra wrapping, no nothing. iykyk 🫶
