[vfio-users] Fwd: Passing through an intregrated Nvidia mobile GPU (NVIDIA Quadro M1000M)

[Brandon Ganem]

I recall a BIOS option to disable Optimus in a dell laptop I had used. Have
you tried turning this off and then assigning the GPU?

When I disabled it in the BIOS, the built in display seemed to run off the
integrated card and the external ports ran off the GPU iirc.
