okay so this is from the Kernel API Manual bestie, and it's literally the page for intel_vgpu_emulate_ggtt_mmio_read β€” the truncated header up top says intel_vgpu_...tt_mmio_read(9) but we're spelling the whole thing out down here, no cap 🫢

πŸ¦‹ SYNOPSIS 🌸

int intel_vgpu_emulate_ggtt_mmio_read (struct intel_vgpu *vgpu ,
unsigned int off , void *p_data , unsigned int bytes );

πŸŽ€ ARGUMENTS πŸŽ€

  • vgpu β€” a vGPU. that's the whole vibe, it's just a vGPU πŸ‘‘
  • off β€” register offset. where in the register we're looking, iykyk
  • p_data β€” data will be returned to guest. like, this is the lil handoff point where the data goes back to the guest πŸ’Œ

that's the whole page bestie, no filler, every option and reference accounted for πŸ’…

and like, the little footer said this one comes from ./drivers/gpu/drm/i915/gvt, dated October 2026, under the intel_vgpu_...tt_mmio_read(9) name β€” so yeah, straight outta the kernel πŸ“ periodt πŸ’œ
