<description summary="Internal protocol for buffer sharing using Vulkan external memory">
This protocol is used internally by Qt for implementing the
qt_server_buffer extension on hardware that supports Vulkan external memory .
This protocol is not part of the Qt API. It exists purely as an
implementation detail and may change from version to
version without notice, or even be removed.

<event name="server_buffer_created">
<description summary="vulkan buffer information">
Informs the client about a newly created server buffer.
The "fd" argument is a POSIX file descriptor representing the
underlying resources of a Vulkan device memory object as defined
in the GL_EXT_memory_object_fd extension.
