💅 pvr_cr_read64(9) — Kernel API Manual 💅

okay bestie, gather round, because we're about to read a whole entire 64-bit register from a PowerVR device and honestly? iconic behavior. ✨

🌸 NAME 🌸

pvr_cr_read64 — read a 64-bit register from a PowerVR device. that's it, that's the vibe. 💖

---

🦋 SYNOPSIS 🦋

u64 pvr_cr_read64 (const struct pvr_device *pvr_dev , u32 reg );

like, you hand it a device and a register, and it hands you back a u64. slay. 🎀

💅 ARGUMENTS 💅

• pvr_dev — target PowerVR device. the main character we're reading from. 👑
• reg — target register. the exact spot we're peeking at. 🔍

⭐ RETURN ⭐

the value of the requested register. no cap, that's literally what you get back. 💫
