[Mesa-dev] [PATCH 0/7] EGL_ANDROID_blob_cache

[Tapani Pälli]

Hello;

Here's a refactored series of EGL_ANDROID_blob_cache. Now cache 
functions are stored in disk_cache struct and the functionality 
called within existing disk_cache put/get code. Problems/errors 
that existed with earlier series are gone.

On Android cache index file is created to MESA_GLSL_CACHE_DIR 
and blobs are  generated under '/data/user_de/0' in application 
specific paths:

androidia_64:/ # find /data/user_de/0/ -name *shader*
/data/user_de/0/com.android.settings/code_cache/com.android.opengl.shaders_cache
/data/user_de/0/com.android.gallery3d/code_cache/com.android.opengl.shaders_cache
/data/user_de/0/com.android.systemui/code_cache/com.android.opengl.shaders_cache
/data/user_de/0/com.rovio.angrybirdsspace.ads/code_cache/com.android.opengl.shaders_cache

(this part is managed by Android but may be interesting to know).

Also SurfaceFlinger manages its own cache as seen in the log output:
01-15 07:40:26.329  2129  2129 D SurfaceFlinger: shader cache generated - 24 shaders in 57.687504 ms

I'm not sure if /sdcard is sane default but I've tried everything 
else (/cache, /data/cache) and failed because of permission errors.

Thanks;

Tapani Pälli (7):
  dri: add interface for EGL_ANDROID_blob_cache extension
  egl: add support for EGL_ANDROID_blob_cache
  disk cache: add callback functionality
  disk cache: support setting MESA_GLSL_CACHE_DIR at compile time
  i965: add __DRI2_BLOB support and set cache functions
  android: ignore MESA_GLSL_CACHE_DISABLE setting
  android: set '/sdcard/' as MESA_GLSL_CACHE_DIR by default
