---

🌸 SYNOPSIS 🌸

int radeon_atpx_power_state (enum vga_switcheroo_client_id id , enum
       vga_switcheroo_state state );

lowkey that's the whole vibe right there, no cap 🫶

🦋 ARGUMENTS 🦋

• id — the GPU you wanna power down/up, bestie. like, which one. that one. 👉
• state — the power state you're requesting ✨ (0 = off, 1 = on, iconic numbering iykyk)

💖 DESCRIPTION 💖

So what does it do? It executes the necessary ATPX function to power down/up the discrete GPU (all asics). that's it, that's the whole job 💅

Returns 0 on success, error on failure. so basically: 0 = we ate, error = not me, not today 😭
