* draw: replace assert(0) with debug_warn_once()Brian Paul2012-01-073-6/+6
| | | | | | If the assertion was hit, it probably meant that we were unable to allocate or map a vertex buffer. Instead of dying in a debug build, issue a warning and continue.

* draw: fix piglit base vertex + user vertex array testsDave Airlie2012-01-061-1/+1
| | | | | | | | | | | | | This fixes draw-elements-base-vertex user_varrays draw-elements-instanced-base-vertex user_varrays for softpipe with no llvm support (DRAW_USE_LLVM=false) I'm not sure if this is the correct answer, but these tests were showing a max_index of 7, then trying to fetch up to 43, maybe it should be fixing max_index earlier somewhere to take care of this.

* gallium/draw: fix two side handlingDave Airlie2011-12-191-18/+9
| | | | | | | | | | | | The code didn't handle the case where front wasn't specified in the vertex shader outputs, but back was. In that case we were doing a copy from back to non-existant front, this code checks we have existant front/backs and only does the copy when they both exist.

* gallium: interface changes necessary to implement transform feedback (v5)Marek Olšák2011-12-154-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* util/draw: replace assertions with conditionals in util_draw_max_index()Brian Paul2011-11-151-5/+15
| | | | | | | | | | | | | | 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]>

* draw/llvm: set draw->pt.user.planes field in draw_set_clip_state()Brian Paul2011-10-111-1/+2
| | | | | | | | | | | | | Previously it was getting set in draw_set_mapped_constant_buffer() but if there were no shader constants, that function wasn't called. So the pt.user.planes field was null and we died when we tried to access the clip planes in the LLVM-generated code. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=41663 Note: This is a candidate for the 7.11 branch. Reviewed-by: José Fonseca <[email protected]>
* draw/llvm: fix hard-coded number of total clip planesBrian Paul2011-10-115-14/+23
| | | | | | | | Instead of 12 use DRAW_TOTAL_CLIP_PLANES. The max number of user-defined clip planes was increased to 8 so the total number of planes is 14. This doesn't fix any specific bug, but clearly the old code was wrong. Reviewed-by: José Fonseca <[email protected]>

* draw: fix edge flag handling in clipper (for unfilled tris/quads/polygons)Brian Paul2011-06-081-5/+57
| | | | | | | | | | | | | | | | | | | | Previously, we were errantly drawing some interior edges of clipped polygons and quads. Also, we were introducing extra edges where polygons intersected the view frustum clip planes. The main problem was that we were ignoring the edgeflags encoded in the primitive header's 'flags' field which are set during polygon/quad ->tri decomposition. We need to observe those during clipping. Since we can't modify the existing vert's edgeflag fields, we need to store them in a parallel array. Edge flags also need to be handled differently for view frustum planes vs. user-defined clip planes. In the former case we don't want to draw new clip edges but in the later case we do. This matches NVIDIA's behaviour and it just looks right. Finally, note that the LLVM draw code does not properly set vertex edge flags. It's OK on the regular software path though.
