[Mesa-dev] [PATCH] mesa: Declare _mesa_meta_begin()/end() as public
Chad Versace
chad at chad-versace.us
Thu Aug 18 13:39:50 PDT 2011
Declare _mesa_meta_begin()/end() in meta.h so that drivers can write
custom meta-ops (such as HiZ resolves for i965).
This necessitates moving the the META_* macros into meta.h. To prevent
naming collisions, this commit renames each macro to be MESA_META_*.
