[Mesa-dev] [RFC 00/10] EGL_ANDROID_blob_cache RFC

[Tapani Pälli]

Hi;

This series enables EGL_ANDROID_blob_cache extension. Overall approach
is to skip linking of shader programs by utilizing functionality of
ARB_get_program_binary extension.

2 first patches are separate and could be pushed in, rest is RFC and 
last patch is additional debug patch that makes Mesa use this cache 
for all EGL apps.

With the last patch I've verified functionality on desktop using 
following apps: glmark2-es, Synmark, glbenchmark2.7.0 (could not make
new gfxbench versions work with EGL ..) and a 3rd party OpenGL ES 2.0
game engine that has relatively complex shaders.

*BUT* there are big issues when using this on Android. Main issue is
that textures are missing from some of the hwui (library used to render
android ui elements) programs. I'm continuing to debug this but wanted
to share to approach and see if someone might spot issues with the
implementation.

Any comments appreciated, thanks!
