This memleak will grow quickly, being possible to see the
following line in dmesg after few minutes of life in the
virtual machine:
[ 706.217388] kmemleak: 10731 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
The patch will remove the line to allow the cleanup
function do its job.

This c
drm/virtio: Conditionally allocate virtio_gpu_fence
We don't want to create a fence for every command submission. It's
only necessary when userspace provides a waitable token for submission.
This could be:
1) bo_handles, to be used with VIRTGPU_WAIT
2) out_fence_fd, to be used with dma_fence apis
3) a ring_idx provided with VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK
+ DRM event API
4) syncobjs in the future
The use case for just submitting a command to the host, and expecting
no response. For example, gfxstream has GFXSTREAM_CONTEXT_PING that
just wakes up the host side worker threads. There's also
CROSS_DOMAIN_CMD_SEND which just sends data to the Wayland server.
This prevents the need to signal the automatically created
virtio_gpu_fence.
In addition, VIRTGPU_EXECBUF_RING_IDX is checked when creating a
DRM event object. VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK is
already defined in terms of per-context rings. It was theoretically
possible to create a DRM event on the global timeline (ring_idx == 0),
if the context enabled DRM event polling. However, that wouldn't
work and userspace (Sommelier). Explicitly disallow it for
clarity.

drm/virtio: Wait for each dma-fence of in-fence array individually
Use dma-fence-unwrap API for waiting each dma-fence of the in-fence array
individually. Sync file's in-fence array always has a non-matching fence
context ID, which doesn't allow to skip waiting of fences with a matching
context ID in a case of a merged sync file fence.

drm/virtio: Refactor and optimize job submission code path
Move virtio_gpu_execbuffer_ioctl() into separate virtgpu_submit.c file,
refactoring and optimizing the code along the way to ease addition of new
features to the ioctl.
The optimization is done by using optimal ordering of the job's submission
steps, reducing code path from the start of the ioctl to the point of
pushing job to virtio queue. Job's initialization is now performed before
in-fence is awaited and out-fence setup is made after sending out job to
virtio.
