2010-10-21draw: implement primitive splitting for primitive restartBrian Paul
2010-08-25draw: specialized cliptesting routinesKeith Whitwell
2010-08-25gallium: Use draw_set_index_buffer and others.Chia-I Wu
Update all drivers to use draw_set_index_buffer, draw_set_mapped_index_buffer, and draw_vbo. Remove draw_set_mapped_element_buffer and draw_set_mapped_element_buffer_range.
2010-08-25draw: Add draw_set_index_buffer and others.Chia-I Wu
This commit adds draw_set_index_buffer, draw_set_mapped_index_buffer, and draw_vbo. The idea behind the new functions is that an index buffer should be a state. draw_arrays and draw_set_mapped_element_buffer are preserved, but the latter will be removed soon.
2010-08-16draw_llvm: fix segfaults on non-SSE2 CPUs where it is disabled (v2)Luca Barbieri
Changes in v2: - Change function name Currently draw_llvm refuses to create itself on non-SSE2 CPUs due to an alleged LLVM bug. However, this is implemented improperly, because other parts of draw still attempt to access draw->llvm, resulting in segfaults. Instead, put the check in debug_get_option_draw_use_llvm, check that before calling draw_llvm_create, and then check whether draw->llvm is non-null everywhere else.
2010-08-16draw: Replace vcache by vsplit.Chia-I Wu
vcache decomposes primitives while vsplit splits primitives. Splitting is generally easier to do and is faster. More importantly, vcache depends on flatshade_first to decompose. The outputs may have incorrect vertex order which is significant to GS.
2010-08-16draw: Replace varray by vsplit.Chia-I Wu
vsplit is a superset of varray. It sets the split flags comparing to varray.
2010-08-16draw: Add new util function draw_pt_trim_count.Chia-I Wu
draw_pt_trim_count is renamed from trim in draw_pt.c.
2010-08-16draw: Simplify frontend interface a little.Chia-I Wu
The run method is simplified to take the start vertex and the vertex count.

first working version of arb_geometry_shader4
2010-06-23draw: don't try to precalculate the pipeline output primitiveKeith Whitwell
We were previously calculating a value which was either the geometry shader output primitive or the application's input primitive, and passing that to the various front/middle/back components for use as the ultimate rendering primtive. Unfortunately, this was not correct -- if the vcache decomposition path is active and geometry shaders are *not* active, we can end up with a third primitive -- specifically the decomposed version of the input primitive. Rather than trying to precalculate this, just let the individual components inform their successors about which primitive type they are recieving.
2010-06-09geometry shaders: make gs work with changable primitives and variable number ↵Zack Rusin
of vertices lots and lots of fixes for geometry shaders. in particular now we work when the gs emits a different primitive than the one the pipeline was started with and also we work when gs emits more vertices than would fit in the original buffer.
2010-06-07draw: don't use llvm engine when geometry shaders activeKeith Whitwell
They aren't implemented for llvm.

2010-04-19draw: Implement index bias.José Fonseca
2010-04-11scons: Make LLVM a black-white dependency.José Fonseca
Now that draw depends on llvm it is very difficult to correctly handle broken llvm installations. Either the user requests LLVM and it needs to supply a working installation. Or it doesn't, and it gets no LLVM accelerate pipe drivers.
2010-04-07draw: init draw->pt.middle.general = NULL just to be safeBrian Paul
This field should be null from the initial calloc() of the draw context, but let's be safe (and improve understanding of the code).
2010-04-06gallium/draw: add additional DRAW_LLVM checkBrian Paul

2010-02-17gallium: remove redundant nr_components field from pipe_vertex_elementRoland Scheidegger
This is a property of the associated src_format pipe format. Hence use util_format_get_nr_components to query this when necessary instead.

2009-12-14gallium: more work for edgeflags changesRoland Scheidegger
fixes, cleanups, etc. not working yet
2009-12-09gallium: first steps to treat edgeflags as regular vertex elementKeith Whitwell
The idea here is to eliminate the set_edgeflags() call in pipe_context by treating edgeflags as a regular vertex element. Edgeflags provoke special treatment in hardware, which means we need to label them in some way, in this case we'll be passing them through the vertex shader and labelling the vertex shader output with a new TGSI semantic (TGSI_SEMANTIC_EDGEFLAG).

2009-06-19draw: use u_reduced_prim() functionBrian Paul
2009-03-13gallium: consolidate bypass_vs and bypass_clipping flagsKeith Whitwell
The draw module provides a similar interface to the driver which is retained as various bits of hardware may be able to take on incremental parts of the vertex pipeline. However, there's no need to advertise all this complexity to the state tracker. There are basically two modes now - normal and passthrough/screen-coords.

2008-07-04gallium: fix trim() function bug when count < firstBrian Paul
If the user called glDrawArrays(GL_TRIANGLES, count=1), trim() returned a very large integer because of the unsigned arithmetic.
