What does "write flush" mean? At least for Gen6+: #define PIPE_CONTROL_RENDER_CACHE_FLUSH (1<<12) If this is invalid before Ironlake, let's change the comment, otherwise ignore. #define PIPE_CONTROL_INSTRUCTION_CACHE_FLUSH (1<<11) /* Gen6+ */ Ben _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
