An additional interface to a wl_surface object, which allows the
|
||
|
|
client to attach additional metadata to the surface.
|
||
|
|
|
||
|
|
If the wl_surface associated with the virtio_gpu_surface_metadata_v1 is

destroyed, all virtio_gpu_surface_metadata_v1 requests except 'destroy'
|

|
|
raise the protocol error no_surface.

|
|
|
||
|
|
If the virtio_gpu_surface_metadata_v1 object is destroyed, the metadata
|
||
|
|
state is removed from the wl_surface. The change will be applied
|
||
|
|
on the next wl_surface.commit.
