[Qemu-devel] [PATCH v4 04/29] dmabuf: add y0_top, pass it to spice

[Marc-André Lureau]

Some scanouts during boot are top-down without it.

y0_top is set from VHOST_USER_GPU_DMABUF_SCANOUT code path in the last
patch of this series.

In current QEMU code base, only vfio/display uses dmabuf API. But the
VFIO query interface doesn't provide or need that detail so far.
