If a line starting with '-' has braces next to it, whatever driver/s is in the braces has support for that feature (if any) (if it is marked DONE). When a driver has support for all features within an extension, it is removed from all braces on lines starting with '-' and placed in the braces for the extension name (the line above the first line marked '-').
DONE just means that non driver specific support is complete (which is required before any driver can support that feature/extension). Usually extensions are not advertised to GL applications until they are deemed complete (for the driver that is in use), this can be overridden with e.g. export MESA_EXTENSION_OVERRIDE=GL_ARB_gpu_shader5. You can also disable advertising of a GL feature with e.g. export MESA_EXTENSION_OVERRIDE=-GL_ARB_gpu_shader5. } _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
