pvr_device_init(9)

✨ pvr_device_init(9) ✨

okay so bestie, we're deep in the Kernel API Manual today and the star of the show is pvr_device_init(9) — literally the glow-up ritual for a PowerVR device 🎀

---

💅 NAME 💅

pvr_device_init — Initialize a PowerVR device. that's it, that's the vibe. we're waking this thing up ✨

---

🌸 SYNOPSIS 🌸

int pvr_device_init (struct pvr_device *pvr_dev );

---

🦋 ARGUMENTS 🦋

• pvr_dev — Target PowerVR device. like, the one you're actually doing this to. the main character of this operation 👑

---

🧚 DESCRIPTION 🧚

so if this function returns successfully, congrats bestie — the device will have been fully initialized 💖 full send, no notes.

otherwise (and this is the responsible part), any parts of the device that got initialized before an error occurred will be de-initialized before returning. she cleans up after herself, periodt. no half-initialized messes left lying around 🌈

---

⚠️ NOTE ⚠️

okay ngl, the initialization steps currently taken are the bare minimum required to read from the control registers. that's it. that's the whole list.

the device is unlikely to function until further initialization steps are added. so like... don't expect fireworks yet 🔥 (or, you know, do expect nothing, which is worse 😭)

the original says, and I quote, [This note should be removed when that happens.] — so bestie, when the extra init steps land, this whole warning block gets deleted 🫶

---

⭐ RETURN ⭐

• 0 on success 🎉
• Any error returned by pvr_device_reg_init
• Any error returned by pvr_device_clk_init, or
• Any error returned by pvr_device_gpu_init

so basically: zero is the slay outcome, anything else means one of those three said "not today" 💀
