intel_vgpu_...e_mmio_write(9)

okay bestie, welcome to intel_vgpu_...e_mmio_write(9) from the Kernel API Manual — this is the page for intel_vgpu_emulate_mmio_write, and it is literally about emulating an MMIO write. no cap, let’s get into it 💅✨

🎀 NAME 🎀

• intel_vgpu_emulate_mmio_write — emulate MMIO write. that’s the whole vibe, and it ate 💖

🌸 SYNOPSIS 🌸

here’s the signature, exactly as written, bestie — do not come for the spacing:

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

✨ ARGUMENTS ✨

• vgpu — a vGPU 🫶 like, the vGPU in question.
• pa — guest physical address. yep, that pa 💫
• p_data — write data buffer. it’s giving “here’s the data we’re writing” 🎀
• bytes — access data length. how many bytes, bestie 🔢

💅 RETURN 💅

Zero on success, negative error code if failed. so 0 is the slay result, and a negative error code means it did not slay 😭 periodt.
