💅 pvr_fw_fini(9) — bestie's guide to shutting down the firmware processor

okay so real talk, this one lives in the Kernel API Manual (yes that's the manual name, we're fancy like that) and it's basically the "okay we're done here, everybody out of the pool" function for the PowerVR firmware processor. ✨

---

🌸 NAME 🌸

pvr_fw_fini — shuts down the firmware processor and frees all the memory that was hanging out with it. like when you finally close all 47 tabs and the laptop stops screaming at you. 😌

---

🦋 SYNOPSIS 🦋

void pvr_fw_fini (struct pvr_device *pvr_dev );

returns nothing (void), takes exactly one pointer, periodt.

---

🎀 ARGUMENTS 🎀

• pvr_dev — the target PowerVR device, i.e. which device we're cleaning up. you gotta tell it who's getting the shutdown treatment, no cap. 👑

ngl there's only the one argument, so there's genuinely no way to mess this up. that's the vibe check passing fr fr.

💀 one tiny thing before you go: this page literally only documents what it does (shutdown + free), so don't go assuming anything about ordering or error behaviour that isn't written here. iykyk, stay in your lane bestie.
