💅 NAME 💅

intel_vgpu_emulate_mmio_read — ok so bestie, this is the one that emulates an MMIO read ✨ (yes, the whole vibe is "pretend the read happened, but make it virtual").

🎀 SYNOPSIS 🎀

int intel_vgpu_emulate_mmio_read (struct intel_vgpu *vgpu , u64 pa ,
       void *p_data , unsigned int bytes );

🌸 ARGUMENTS 🌸

• vgpu — a vGPU 🫶 like, the virtual GPU we're doing all this for, main character energy fr.
• pa — guest physical address 📍 the spot in guest-physical-land we're reading from.
• p_data — data return buffer 🍓 the lil bucket where the data comes back to you.
• bytes — access data length 📏 how many bytes this access is asking for, no cap.

👑 RETURN 👑

Zero on success 💖, negative error code if failed 😭 — so like, 0 = slay, anything negative = it's giving struggle.
