Stop using ttm helpers, use the virtio_gpu_array_* helpers (which work on the reservation objects directly) instead. Also store the object array in struct virtio_gpu_vbuffer, so we explicitly keep a reference of all buffers used instead of depending on ttm_bo_put() checking whenever the object is actually idle before releasing it. New workflow: (1) All gem objects needed by a command are added to a virtio_gpu_object_array. (2) All reservation objects will be locked (virtio_gpu_array_lock_resv). (3) virtio_gpu_fence_emit() completes fence initialization. (4) fence gets added to the objects, reservation objects are unlocked (virtio_gpu_array_add_fence, virtio_gpu_array_unlock_resv). (5) virtio command is submitted to the host. (6) The completion callback (virtio_gpu_dequeue_ctrl_func) will drop object references and free virtio_gpu_object_array. v6: rewrite most of the patch.

Stop using ttm helpers, use the virtio_gpu_array_* helpers instead. Due to using the gem reservation object it is initialized and ready for use before calling ttm_bo_init. So we can simply use the standard fencing workflow and drop the tricky logic which checks whenever the command is in flight still. v6: rewrite most of the patch.

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.
