* util: add helper function util_dump_draw_infoMarek Olšák2012-01-052-0/+34

* u_format: implement fetch_rgba_uint and fetch_rgba_sint for integer formatsMarek Olšák2012-01-053-4/+32
| | | | | | | | | | | | | Fetching int as float and vice versa is not allowed. Fetching unsigned int as signed int and vice versa is not allowed either. Doing conversions like that isn't allowed for samplers in OpenGL. The three hooks could be consolidated into one fetch hook, which would fetch uint as uint32, sint as sint32, and everything else as float. The receiving parameter would be void*. This would be useful for implementing vertex fetches for shader model 4.0, which has untyped registers. Reviewed-by: Dave Airlie <[email protected]>
* u_vbuf: translate per-vertex, per-instance, and constant attribs separatelyMarek Olšák2012-01-051-104/+236
| | | | | | | We don't wanna convert per-instance or constant (zero-stride) attribs into ordinary vertex attribs. More importantly, the translation of instance attribs now finally works.

| | | | | | | | | | | | inv_swizzles is used in lp_tile_soa.py to create lp_tile_soa.c, we overwrite swizzles if they are already set. This results in the i8 format getting alpha instead of red, and the l8 format getting blue instead of red.

* gallium: interface changes necessary to implement transform feedback (v5)Marek Olšák2011-12-151-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* gallium: separate out floating-point CAPs into its own enumMarek Olšák2011-11-221-1/+1
| | | | | | | | | | | | | | | The motivation behind this is to add some self-documentation in the code about how each CAP can be used. The idea is: - enum pipe_cap is only valid in get_param - enum pipe_capf is only valid in get_paramf Which CAPs are floating-point have been determined based on how everybody except svga implemented the functions. svga have been modified to match all the other drivers. Besides that, the floating-point CAPs are now prefixed with PIPE_CAPF_.

* u_vbuf_mgr: correctly compute max vertex count from hw buffersMarek Olšák2011-11-202-26/+34

* util/draw: replace assertions with conditionals in util_draw_max_index()Brian Paul2011-11-151-8/+24
| | | | | | | | | | | | | | Don't assert/die if a VBO is too small. Return zero instead. For debug builds, emit a warning message since this is an unusual situation that might indicate that there's a bug in the app. Note that util_draw_max_index() now returns max_index+1 instead of max_index. This lets us return zero to indicate that one of the VBOs is too small to draw anything. Fixes a failure with the new piglit vbo-too-small test. Reviewed-by: José Fonseca <[email protected]>
