I’m looking forward to you reply. > I'm no kernel dev, but it's worth mentioning a lot of infrastructure for GPU virtualisation was merged in 4.10; specifically the GVT functionality written by Intel which makes use of the VFIO mediated device framework which itself landed in 4.9, I believe (I could be mistaken). It may be worth while asking on the intel-gvt-dev list [1] too, as we would surely all benefit from having standard interfaces for virtual GPUs regardless of hardware vendor. You may wish to have a look at the following files & directories in the kernel source tree: Documentation/vfio-mediated-device.txt drivers/vfio/mdev/ drivers/gpu/drm/i915/gvt/ None of this is specifically related to nouveau, but there's certainly some common infrastructure (mdev) that could be utilised.
