<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.
