virtio-gpu basically needs a sg_table for the bo, to tell the host where the backing pages for the object are. So the gem shmem helpers are a perfect fit. Some drm_gem_object_funcs need thin wrappers to update the host state, but otherwise the helpers handle everything just fine. Once the fencing was sorted the switch was surprisingly easy and for the most part just removing the ttm code. v4: fix drm_gem_object_funcs name.

This is the virtual GPU driver for virtio. It can be used with

|
QEMU based VMMs (like KVM or Xen).

If unsure say M.
