| EGL Extension #not assigned |
| |
| Dependencies |
| |
| Requires 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 an implementation specific wayland interface, allows the |
| EGL implementation to define specific wayland requests and events, |
| needed for buffer sharing in an 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, |
| NULL context and an empty attribute_list. |
