* EGL_MUTABLE_RENDER_BUFFER_BIT_KHR and whose active EGL_RENDER_BUFFER (as |

* opposed to any pending, requested change to EGL_RENDER_BUFFER) is |
|
* EGL_SINGLE_BUFFER. |
|
* |
|
* If buffer_mask contains __DRI_IMAGE_BUFFER_SHARED, then must contains no |
|
* other bits. As a corollary, a __DRIdrawable that has a "shared" buffer |
|
* has no front nor back buffer. |
|
* |
|
* The loader returns __DRI_IMAGE_BUFFER_SHARED in buffer_mask if and only |
|
* if: |
|
* - The loader supports __DRI_MUTABLE_RENDER_BUFFER_LOADER. |
|
* - The driver supports __DRI_MUTABLE_RENDER_BUFFER_DRIVER. |
|
* - The EGLConfig of the drawable EGLSurface contains |
|
* EGL_MUTABLE_RENDER_BUFFER_BIT_KHR. |
|
* - The EGLContext's EGL_RENDER_BUFFER is EGL_SINGLE_BUFFER. |
|
* Equivalently, the EGLSurface's active EGL_RENDER_BUFFER (as |
|
* opposed to any pending, requested change to EGL_RENDER_BUFFER) is |
|
* EGL_SINGLE_BUFFER. (See the EGL 1.5 and |
|
* EGL_KHR_mutable_render_buffer spec for details about "pending" vs |
|
* "active" EGL_RENDER_BUFFER state). |
|
* |
|
* A shared buffer is similar to a front buffer in that all rendering to the |
|
* buffer should appear promptly on the screen. It is different from |
|
* a front buffer in that its behavior is independent from the |
|
* GL_DRAW_BUFFER state. Specifically, if GL_DRAW_FRAMEBUFFER is 0 and the |
|
* __DRIdrawable's buffer_mask is __DRI_IMAGE_BUFFER_SHARED, then all |
|
* rendering should appear promptly on the screen if GL_DRAW_BUFFER is not |
|
* GL_NONE. |
|
* |
|
* The difference between a shared buffer and a front buffer is motivated |
|
* by the constraints of Android and OpenGL ES. OpenGL ES does not support |
|
* front-buffer rendering. Android's SurfaceFlinger protocol provides the |
|
* EGL driver only a back buffer and no front buffer. The shared buffer |
|
* mode introduced by EGL_KHR_mutable_render_buffer is a backdoor though |
|
* EGL that allows Android OpenGL ES applications to render to what is |
|
* effectively the front buffer, a backdoor that required no change to the |
|
* OpenGL ES API and little change to the SurfaceFlinger API. |

|
* |
|
* To support this extension: |

|
* - The driver should create at least one __DRIconfig with |

* __DRI_ATTRIB_MUTABLE_RENDER_BUFFER. This is strongly recommended but |
|
* not required. |
|
* |
|
* - The driver must be able to handle __DRI_IMAGE_BUFFER_SHARED if |

* returned by __DRIimageLoaderExtension:getBuffers(). |
|
* |
|
* - When rendering to __DRI_IMAGE_BUFFER_SHARED, it must call |
|
* __DRImutableRenderBufferLoaderExtension::displaySharedBuffer() in |
|
* response to glFlush and glFinish. (This requirement is not documented |
|
* in EGL_KHR_mutable_render_buffer, but is a de-facto requirement in the |
|
* Android ecosystem. Android applications expect that glFlush will |
|
* immediately display the buffer when in shared buffer mode, and Android |
|
* drivers comply with this expectation). It :may: call |
|
* displaySharedBuffer() more often than required. |
|
* |
|
* - When rendering to __DRI_IMAGE_BUFFER_SHARED, it must ensure that the |
|
* buffer is always in a format compatible for display because the |
|
* display engine (usually SurfaceFlinger or hwcomposer) may display the |
|
* image at any time, even concurrently with 3D rendering. For example, |
|
* display hardware and the GL hardware may be able to access the buffer |
|
* simultaneously. In particular, if the buffer is compressed then take |
|
* care that SurfaceFlinger and hwcomposer can consume the compression |
|
* format. |
