Adding multihead support turned out to not be that easy. There are
corner cases like a single framebuffer spawning both heads. Also it
would be useful to somehow hint to the guest which heads it

Adding multihead support turned out to not be that easy. There are

Add VFIO_DEVICE_QUERY_GFX_PLANE ioctl command to let user query and get
a plane and its related information. So far, two types of buffers are
supported: buffers based on dma-buf and buffers based on region.
This ioctl can be invoked with:
1) either DMABUF or REGION flag. Vendor driver returns a
