| Version 2, July 23, 2014 |
| |
| Number |
| |
| EGL Extension #76 |
| |
| Dependencies |
| |
| EGL 1.2 is required. |
| |
| EGL_KHR_image_base is required. |
| |
| This extension is written against the wording of the EGL 1.2 |
| Specification. |
| |
| Overview |
| |
| This extension enables using a Tizen native buffer (struct |
| native_buffer) as an EGLImage source. |
| |
| New Types |
| |
| None. |
| |
| New Procedures and Functions |
| |
| None. |
| |
| New Tokens |
| |
| Accepted by the <target> parameter of eglCreateImageKHR: |
| |
| EGL_NATIVE_BUFFER_TIZEN 0x32A0 |
| |
| Changes to Chapter 3 of the EGL 1.2 Specification (EGL Functions and Errors) |
| |
| Add to section 2.5.1 "EGLImage Specification" (as defined by the |
| EGL_KHR_image_base specification), in the description of |
| eglCreateImageKHR: |
| |
| "Values accepted for <target> are listed in Table aaa, below. |
| |
| +-------------------------+--------------------------------------+ |
| | <target> | Notes | |
| +-------------------------+--------------------------------------+ |
| | EGL_NATIVE_BUFFER_TIZEN | Used for Tizen native_buffer objects | |
| +-------------------------+--------------------------------------+ |
| Table aaa. Legal values for eglCreateImageKHR <target> parameter |
| |
| ... |
| |
| If <target> is EGL_NATIVE_BUFFER_TIZEN, <dpy> must be a valid display, |
| <ctx> must be EGL_NO_CONTEXT, <buffer> must be a pointer to a valid |
| native_buffer object (cast into the type EGLClientBuffer), and |
| attributes other than EGL_IMAGE_PRESERVED_KHR are ignored." |
| |
| Add to the list of error conditions for eglCreateImageKHR: |
| |
| "* If <target> is EGL_NATIVE_BUFFER_TIZEN and <buffer> is not a |
| pointer to a valid native_buffer, the error EGL_BAD_PARAMETER |
| is generated. |
| |
| * If <target> is EGL_NATIVE_BUFFER_TIZEN and <ctx> is not |
| EGL_NO_CONTEXT, the error EGL_BAD_CONTEXT is generated. |
| |
| * If <target> is EGL_NATIVE_BUFFER_TIZEN and <buffer> was created |
| with properties (format, usage, dimensions, etc.) not supported by |
| the EGL implementation, the error EGL_BAD_PARAMETER is generated." |
| |
| Issues |
| |
| 1. Should this extension define what combinations of native_buffer |
| properties implementations are required to support? |
| |
| RESOLVED: No. |
| |
| The requirements have evolved over time and will continue to change with |
| future Tizen releases. The minimum requirements for a given Tizen |
| version should be documented by that version. |
