+ <description summary="protocol for providing explicit synchronization">
+ This protocol allows clients to request explicit synchronization for
+ buffers. It is tied to the Linux DRM synchronization object framework.
+
+ Synchronization refers to co-ordination of pipelined operations performed
+ on buffers. Most GPU clients will schedule an asynchronous operation to
+ render to the buffer, then immediately send the buffer to the compositor
+ to be attached to a surface.
+
+ With implicit synchronization, ensuring that the rendering operation is
+ complete before the compositor displays the buffer is an implementation
+ detail handled by either the kernel or userspace graphics driver.
+
+ By contrast, with explicit synchronization, DRM synchronization object
+ timeline points mark when the asynchronous operations are complete. When
+ submitting a buffer, the client provides a timeline point which will be
+ waited on before the compositor accesses the buffer. The client can also
+ provide a timeline point that the compositor will signal when it no longer
+ needs to access the buffer contents for the purposes of the surface commit.
+
+ Linux DRM synchronization objects are documented at:
+ https://dri.freedesktop.org/docs/drm/gpu/drm-mm.html#drm-sync-objects
+
+ Warning! The protocol described in this file is currently in the testing
+ phase. Backward compatible changes may be added together with the
+ corresponding interface version bump. Backward incompatible changes can
+ only be done by creating a new major version of the extension.
