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. + + Attribute Type Notes + ------------------------------ ------- --------------------------- + EGL_FRAMEBUFFER_TARGET_ANDROID boolean whether use as a HWComposer + framebuffer target layer is + supported + + Section 3.4, Configuration Management, add a row to Table 3.4. + + Attribute Default Selection Sort Sort + Criteria Order Priority + ------------------------------ ------------- --------- ----- -------- + EGL_FRAMEBUFFER_TARGET_ANDROID EGL_DONT_CARE Exact None + + Section 3.4, Configuration Management, add a paragraph at the end of the + subsection titled Other EGLConfig Attribute Descriptions. + + 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. + + Section 3.4.1, Querying Configurations, change the last paragraph as follow + + EGLConfigs are not sorted with respect to the parameters + EGL_BIND_TO_TEXTURE_RGB, EGL_BIND_TO_TEXTURE_RGBA, EGL_CONFORMANT, + EGL_LEVEL, EGL_NATIVE_RENDERABLE, EGL_MAX_SWAP_INTERVAL, + EGL_MIN_SWAP_INTERVAL, EGL_RENDERABLE_TYPE, EGL_SURFACE_TYPE, + EGL_TRANSPARENT_TYPE, EGL_TRANSPARENT_RED_VALUE, + EGL_TRANSPARENT_GREEN_VALUE, EGL_TRANSPARENT_BLUE_VALUE, and + EGL_RECORDABLE_ANDROID. + +Issues + + +Revision History + +#1 (Jamie Gennis, September 20, 2012) + - Initial draft. |
