(jgennis 'at' google.com) Status Draft. Version Version 1, September 20, 2012 Number EGL Extension #XXX Dependencies Requires EGL 1.0 This extension is written against the wording of the EGL 1.4 Specification Overview Android supports a number of different ANativeWindow implementations that can be used to create an EGLSurface. One implementation, which is used to send the result of performing window composition to a display, may have some device-specific restrictions. Because of this, some EGLConfigs may be incompatible with these ANativeWindows. This extension introduces a new boolean EGLConfig attribute that indicates whether the EGLConfig supports rendering to an ANativeWindow for which the buffers are passed to the HWComposer HAL as a framebuffer target layer. New Types None. New Procedures and Functions None. New Tokens Accepted by the <attribute> parameter of eglGetConfigAttrib and the <attrib_list> parameter of eglChooseConfig: EGL_FRAMEBUFFER_TARGET_ANDROID 0x3147 Changes to Chapter 3 of the EGL 1.4 Specification (EGL Functions and Errors) Section 3.4, Configuration Management, add a row to Table 3.1.

EGL_FRAMEBUFFER_TARGET_ANDROID is a boolean indicating whether the config may be used to create an EGLSurface from an ANativeWindow for which the buffers are to be passed to HWComposer as a framebuffer target layer.
