💅 intel_vgpu_opregion_base_write_handler(9) 💅

okay so this is a page from the Kernel API Manual, and honestly? it's a little icon of a function. bestie, we're talking about the Opregion base register write handler — the lil guy who handles writes to the opregion base register. main character energy fr ✨

🌸 SYNOPSIS 🌸

int intel_vgpu_opregion_base_write_handler (struct intel_vgpu *vgpu ,
       u32 gpa );

that's it. that's the whole vibe check. 💖

🎀 ARGUMENTS 🎀

• vgpu — a vGPU. literally just a vGPU. it's the star of the show 👑
• gpa — guest physical address of opregion 📍 (yes, physical, not virtual — keep up bestie)

⭐ RETURN ⭐

Zero on success 🎉 — and if it flops, you get a negative error code. no cap, negative means bad vibes. 😭

ngl if you see a negative number coming back, something did not slay. check it. 💀
