* gallium: interface changes necessary to implement transform feedback (v5)Marek Olšák2011-12-1524-89/+210
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Namely: - EXT_transform_feedback - ARB_transform_feedback2 - ARB_transform_feedback_instanced The old interface was not useful for OpenGL and had to be reworked. This interface was originally designed for OpenGL, but additional changes have been made in order to make st/d3d1x support easier. The most notable change is the stream-out info must be linked with a vertex or geometry shader and cannot be set independently. This is due to limitations of existing hardware (special shader instructions must be used to write into stream-out buffers), and it's also how OpenGL works (stream outputs must be specified prior to linking shaders). Other than that, each stream output buffer has a "view" into it that internally maintains the number of bytes which have been written into it. (one buffer can be bound in several different transform feedback objects in OpenGL, so we must be able to have several views around) The set_stream_output_targets function contains a parameter saying whether new data should be appended or not. Also, the view can optionally be used to provide the vertex count for draw_vbo. Note that the count is supposed to be stored in device memory and the CPU never gets to know its value. OpenGL way | Gallium way ------------------------------------ BeginTF = set_so_targets(append_bitmask = 0) PauseTF = set_so_targets(num_targets = 0) ResumeTF = set_so_targets(append_bitmask = ~0) EndTF = set_so_targets(num_targets = 0) DrawTF = use pipe_draw_info::count_from_stream_output v2: * removed the reset_stream_output_targets function * added a parameter append_bitmask to set_stream_output_targets, each bit specifies whether new data should be appended to each buffer or not. v3: * added PIPE_CAP_STREAM_OUTPUT_PAUSE_RESUME for ARB_tfb2, note that the draw-auto subset is always required (for d3d10), only the pause/resume functionality is limited if the CAP is not advertised v4: * update gallium/docs v5: * compactified struct pipe_stream_output_info, updated dump/trace

* mesa: implement DrawTransformFeedback from ARB_transform_feedback2Marek Olšák2011-12-1526-98/+205
| | | | | | | | | | | | | | It's like DrawArrays, but the count is taken from a transform feedback object. This removes DrawTransformFeedback from dd_function_table and adds the same function to GLvertexformat (with the function parameters matching GL). The vbo_draw_func callback has a new parameter "struct gl_transform_feedback_object *tfb_vertcount". The rest of the code just validates states and forwards the transform feedback object into vbo_draw_func.

* glsl: Fix crashes caused by Bison error messages involving "'%'".Kenneth Graunke2011-12-131-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Invalid shaders containing the character % at an unexpected location would cause Bison to call yyerror with a message of: syntax error, unexpected '%' Bison expects yyerror() to take a string, while _mesa_glsl_error() is a printf-style function. This hit the classic printf string escape issue: _mesa_glsl_error(loc, state, "unexpected '%'"); // invalid! _mesa_glsl_error(loc, state, "%s", "unexpected '%'"); // correct. This caused assertion failures after ralloc_asprintf_append called vsnprintf to determine the length of the text that would be printed: vsnprintf would see the invalid format and return -1, an invalid length. The solution is to define a proper yyerror() wrapper function that calls _mesa_glsl_error with the "%s". Since we compile with -p "_mesa_glsl", yyerror is defined as: #define yyerror _mesa_glsl_error So we have to #undef yyerror in order to be able to declare it.
