Expand description

VFIO_DEVICE_QUERY_GFX_PLANE - _IOW(VFIO_TYPE, VFIO_BASE + 14, struct vfio_device_query_gfx_plane)

Set the drm_plane_type and flags, then retrieve the gfx plane info.

flags supported:

VFIO_GFX_PLANE_TYPE_PROBE and VFIO_GFX_PLANE_TYPE_DMABUF are set to ask if the mdev supports dma-buf. 0 on support, -EINVAL on no support for dma-buf.
VFIO_GFX_PLANE_TYPE_PROBE and VFIO_GFX_PLANE_TYPE_REGION are set to ask if the mdev supports region. 0 on support, -EINVAL on no support for region.
VFIO_GFX_PLANE_TYPE_DMABUF or VFIO_GFX_PLANE_TYPE_REGION is set with each call to query the plane info.
Others are invalid and return -EINVAL.

Note:

Plane could be disabled by guest. In that case, success will be returned with zero-initialized drm_format, size, width and height fields.
x_hot/y_hot is set to 0xFFFFFFFF if no hotspot information available

Return: 0 on success, -errno on other failure.
