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.
