radeon_regis...atpx_handler(9)

💅 NAME 💅

okay so bestie, welcome to the radeon_register_atpx_handler page — it's from the Kernel API Manual (yes, the radeon_regis...atpx_handler(9) one, the name got truncated by the terminal and honestly who among us). This function's whole entire job? register with vga_switcheroo. that's it. that's the vibe. 🦋

---

✨ SYNOPSIS ✨

void radeon_register_atpx_handler (void );

literally no parameters, no returns, just vibes and a void where the arguments should be. icon behavior honestly. 🎀

---

🫶 ARGUMENTS 🫶

• void — no arguments. none. zero. the function said "i need nothing from you" and honestly? respect. 💅

---

🔥 DESCRIPTION 🔥

so what does it actually do, you ask? it registers the PX callbacks with vga_switcheroo — and yes, that applies to all asics. every single one. no exceptions, no cap. 🔥

think of it as handing your graphics-switching homework over to the vga_switcheroo teacher so the hybrid graphics situation can actually get handled properly. it's giving main character energy for the PX callback pipeline. ✨
