[Mesa-dev] [PATCH 2/3] egl_dri2: add support for Android

Tue Aug 23 20:10:35 PDT 2011
Add platform_android.c that supports _EGL_PLAFORM_ANDROID. It works
with drm_gralloc, where back buffers of windows are backed by GEM
objects.
In Android a native window has a queue of back buffers allocated by the
server, through drm_gralloc. For each frame, EGL needs to
dequeue the next back buffer
render to the buffer
enqueue the buffer
After enqueuing, the buffer is no longer valid to EGL. A window has no
depth buffer or other aux buffers. They need to be allocated locally by
EGL.
