+    Version 3 - April 11, 2018
+
+Number

+    127
+
+Extension Type
+
+    EGL display extension
+
+Dependencies
+
+    Requires the EGL_KHR_stream extension.
+
+    Requires either the EGL_KHR_stream_cross_process_fd or 
+    EGL_NV_stream_remote extensions.
+    
+    This extension is written based on the wording of version 27 of 
+    the EGL_KHR_stream extension.
+
+Overview:
+
+    The EGL_KHR_stream_cross_process_fd and EGL_NV_stream_remote 
+    extensions do not guarantee that when the state of the EGLStream
+    object representing one endpoint of the stream changes, 
+    the state of the other endpoint will immediately reflect 
+    that change. Depending on the implementation, there may be some
+    latency in the propagation of state changes.
+
+    This latency will not affect any applications which rely solely
+    on the stream itself for communication. State changes made on 
+    one side will eventually be visible on the other side, 
+    and can then be responded to.
+
+    This only affects applications which use some additional means of 
+    communication outside of the stream itself, which may encounter 
+    race conditions. In particular, if an application inserts a frame
+    into a stream, then sends a message to the other side indicating 
+    that the frame is ready, the other side may encounter an error if
+    it tries to acquire the frame and it is not yet available.
+
+    One solution is to force all operations that change state of one 
+    endpoint to behave synchronously, and not return until the change
+    is reflected on the other endpoint. However this adds undesirable 
+    delays for the majority of applications and operations where such 
+    synchronization is not required. This extension instead provides
+    a means for applications to explicitly invoke such 
+    synchronization only where required.
+
+New types
+
+    None
+
+New Procedures and functions
+
+    EGLBoolean eglStreamFlushNV(
+        EGLDisplay       dpy,
+        EGLStreamKHR     stream); 
+
+New Tokens
+    
+    None
+
+Add a new subsection "3.10.x EGLStream flush" at the end of section 
+"3.10 EGLStreams" in EGL_KHR_stream extension.
+
+    The command
+
+        EGLBoolean eglStreamFlushNV(
+            EGLDisplay       dpy,
+            EGLStreamKHR     stream);
+
+    When called with either producer or consumer endpoint of the 
+    stream, will block until any state changes made to this endpoint 
+    prior to the call are visible on the EGLStream object of the other
+    endpoint.
+
+    On success, EGL_TRUE will be returned. On failure, EGL_FALSE will
+    be returned and an error will be generated.
+
+        - EGL_BAD_STREAM_KHR is generated if <stream> is not a valid
+          EGLStream.
+
+        - EGL_BAD_STATE_KHR is generated if <stream> is in
+          EGL_STREAM_STATE_DISCONNECTED_KHR state.
+
+        - EGL_BAD_DISPLAY is generated if <dpy> is not a valid
+          EGLDisplay.
+
+        - EGL_NOT_INITIALIZED is generated if <dpy> is not initialized.
+
+Issues
+
+    1.  When both producer and consumer are connected to a single 
+        EGLStream object, what happens when eglStreamFlushNV is called?
+
+        RESOLVED: The function returns without any blocking.
