We'll need these parameters when allocating a dma_fence. The use case for this is multiple synchronizations timelines. The maximum number of timelines per 3D instance will be 32. Usually, only 2 are needed -- one for CPU commands, and another for GPU commands. As such, we'll need to specify these parameters when allocating a dma_fence. vgdev->fence_drv.context is the "default" fence context for 2D mode and old userspace.
