+
+ EGL Extension #not assigned
+
+Dependencies
+
+ Reguires EGL 1.4 or later. This extension is written against the
+ wording of the EGL 1.4 specification.
+
+ EGL_KHR_base_image is required.
+
+Overview
+
+ This extension provides entry points for binding and unbinding the
+ wl_display of a Wayland compositor to an EGLDisplay. Binding a
+ wl_display means that the EGL implementation should provide one or
+ more interfaces in the Wayland protocol to allow clients to create
+ wl_buffer objects. On the server side, this extension also
+ provides a new target for eglCreateImageKHR, to create an EGLImage
+ from a wl_buffer
+
+ Adding a implementation specific wayland interface, allows the
+ EGL implementation to define specific wayland requests and events,
+ needed for buffer sharing in a EGL wayland platform.
+
+IP Status
+
+ Open-source; freely implementable.
+
+New Procedures and Functions
+
+ EGLBoolean eglBindWaylandDisplayWL(EGLDisplay dpy,
+ struct wl_display *display);
+
+ EGLBoolean eglUnbindWaylandDisplayWL(EGLDisplay dpy,
+ struct wl_display *display);
+
+New Tokens
+
+ Accepted as <target> in eglCreateImageKHR
+
+ EGL_WAYLAND_BUFFER_WL 0x31D5
+
+Additions to the EGL 1.4 Specification:
+
+ To bind a server side wl_display to an EGLDisplay, call
+
+ EGLBoolean eglBindWaylandDisplayWL(EGLDisplay dpy,
+ struct wl_display *display);
+
+ To unbind a server side wl_display from an EGLDisplay, call
+
+ EGLBoolean eglUnbindWaylandDisplayWL(EGLDisplay dpy,
+ struct wl_display *display);
+
+ eglBindWaylandDisplayWL returns EGL_FALSE when there is already a
+ wl_display bound to EGLDisplay otherwise EGL_TRUE.
+
+ eglUnbindWaylandDisplayWL returns EGL_FALSE when there is no
+ wl_display bound to the EGLDisplay currently otherwise EGL_TRUE.
+
+ Import a wl_buffer by calling eglCreateImageKHR with
+ wl_buffer as EGLClientBuffer, EGL_WAYLAND_BUFFER_WL as the target,
+ and an empty attribute_list.
