Given that Intel's GVT patches may potentially be merged in 4.10, I'm curious as to whether this will change the VFIO + Optimus situation.
Since GVT works with unmodified guest drivers for the Intel card, and can provide either direct access to the IGPU's outputs or work in a composited mode, is it possible that a Optimus cards might finally be usable in VMs if the IGPU is made available to the VM via GVT? If not, what further work would be required for such a setup to work with VFIO?
