2010-09-25draw: Fullfil the new min_lod/max_lod/lod_bias/border_color dynamic stateJosé Fonseca
2010-09-23draw: Prevent clipped vertices overflow.José Fonseca
Some pathological triangles cause a theoritically impossible number of clipped vertices. The clipper will still assert, but at least release builds will not crash, while this problem is further investigated.
2010-09-23draw: don't apply flatshading to clipped tris with <3 vertsKeith Whitwell
If a triangle was completely culled by clipping, we would still try to fix up its provoking vertex.
2010-09-21draw: new draw_fs.[ch] filesBrian Paul
2010-09-20draw: check bitshift against PIPE_MAX_SHADER_OUTPUSBrian Paul
2010-09-20draw: fix test for using the wide-point stageBrian Paul
As it was, we weren't obeying the draw->pipeline.point_sprite state. Fixes point sprites in llvmpipe driver.
2010-09-17gallium: rework handling of sprite_coord_enable stateBrian Paul
Implement the pipe_rasterizer_state::sprite_coord_enable field in the draw module (and softpipe) according to what's specified in the documentation. The draw module can now add any number of extra vertex attributes to a post-transformed vertex and generate texcoords for those attributes per sprite_coord_enable. Auto-generated texcoords for sprites only worked for one texcoord unit before. The frag shader gl_PointCoord input is now implemented like any other generic/texcoord attribute. The draw module now needs to be informed about fragment shaders since we need to look at the fragment shader's inputs to know which ones need auto-generated texcoords. Only softpipe has been updated so far.

2010-09-14gallium: introduce get_shader_param (ALL DRIVERS CHANGED) (v3)Luca Barbieri
Changes in v3: - Also change trace, which I forgot about Changes in v2: - No longer adds tessellation shaders Currently each shader cap has FS and VS versions. However, we want a version of them for geometry, tessellation control, and tessellation evaluation shaders, and want to be able to easily query a given cap type for a given shader stage. Since having 5 duplicates of each shader cap is unmanageable, add a new get_shader_param function that takes both a shader cap from a new enum and a shader stage. Drivers with non-unified shaders will first switch on the shader and, within each case, switch on the cap. Drivers with unified shaders instead first check whether the shader is supported, and then switch on the cap. MAX_CONST_BUFFERS is now per-stage. The geometry shader cap is removed in favor of checking whether the limit of geometry shader instructions is greater than 0, which is also used for tessellation shaders. WARNING: all drivers changed and compiled but only nvfx tested
2010-09-09draw: minor reformattingBrian Paul
2010-09-02draw: Include missing headers in draw_vs_aos.h.Vinson Lee
Include tgsi_exec.h for TGSI_EXEC_NUM_TEMPS. Include draw_vs.h for draw_vs_varient.
2010-08-28draw: Include missing header in draw_vs_llvm.c.Vinson Lee
Include p_screen.h for completely type to pipe_screen.

2010-08-25draw: Remove UNDEFINED_VERTEX_ID checks in emit pathes.Chia-I Wu
UNDEFINED_VERTEX_ID is used by draw_pipe_vbuf to decide whether a vertex has been emitted or not. The non-pipeline pathes do not use it (they tell the frontend the max vertex count when prepare() is called).
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.
2010-08-22draw: reduce the size of the llvm variant keyKeith Whitwell
2010-08-22draw: Don't assert if indices point outside vertex buffer.José Fonseca
This is valid input, and asserting here does causes the test suites that verify this to crash. Also, the assert was wrongly accepting the case max_index == vert_info->count which, IIUC, is the first vertex outside the buffer. Assuming the vert_info->count is precise (which often is not the case).
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.
2010-08-16drwa: Fix polygon edge flags.Chia-I Wu
Fix a copy-and-paste error introduced by f141abdc8fdbff41e16b0ce53fa3fa8fba32a7f9.
2010-08-16draw: No need to make max_vertices even.Chia-I Wu
Triangle strip alternates the front/back orientation of its triangles. max_vertices was made even so that varray never splitted a triangle strip at the wrong positions. It did not work with triangle strips with adjacencies. And it is no longer relevant with vsplit.
2010-08-16draw: Remove DRAW_PIPE_MAX_VERTICES and DRAW_PIPE_FLAG_MASK.Chia-I Wu
The higher bits of draw elements are no longer used for the stipple or edge flags.
2010-08-16drwa: Add PRIMITIVE macro to vsplit.Chia-I Wu
PRIMITIVE is used by the indexed path to flush the entire primitive with custom vertex count checks. It replaces the existing fast path.
2010-08-16draw: last_vertex_last is always true for GS and SO.Chia-I Wu
That is, OpenGL decomposition rule is assumed. There should be a pipe_context state to specify the rules.
2010-08-16draw: Remove varray and vcache.Chia-I Wu
They have been deprecated by vsplit.
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 vsplit frontend.Chia-I Wu
vsplit is based on varray. It sets the split flags when a primitive is splitted. It also has support for indexed primitives. For indexed primitives, unlike vcache, vsplit splits the primitives instead of decomposes them.
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.
2010-08-16draw: Add prim flags to middle ends.Chia-I Wu
Update the middle end interface to pass the primitive flags from the frontends to the pipeline. No frontend sets the flags yet.
2010-08-16draw: Add flags to draw_prim_info.Chia-I Wu
A primitive may be splitted in frontends. The splitted primitives should convey certain flag bits so that the decomposer can correctly decide the stipple or edge flags. This commit adds flags to draw_prim_info and updates the decomposer to honor the flags. Frontends and middle ends will be updated later.
2010-08-08draw: Remove unused variable.José Fonseca
2010-08-08draw: Use the correct type for integersnobled
Two integers were being operated on as a vector of floats in draw_llvm_generate(). This bug got uncovered by fixing this bug: http://bugs.freedesktop.org/29407
2010-08-07draw: Add an assertion to varray's version of trim().Chia-I Wu
Assert that "first" is always smaller than "count" and add reasoning. It would be better to simply fix trim(), but it is used in tight loops right now.
2010-08-07draw: Fix draw_pt_split_prim for primitives with adjacency.Chia-I Wu
Some primitives with adjacency have their "incr" wrong.
2010-08-07draw: Assert that only the first vetex may have flags set.Chia-I Wu
642d5ba79abc6a231a5fdabb3454b9b082b0d7f8 removed flags masking for vertices other than the first one. Add assertions to be on the safe side.
2010-08-06draw: Avoid mixed declarations and code.Chia-I Wu
Do not expand LOCAL_VARS to void expression. Otherwise, declarations and code will be mixed when more variables are declared in FUNC_ENTER. This fixes fdo bug #29416.
2010-08-06draw: Remove unnecessary vertex flag ANDs.Chia-I Wu
Vertex flags are a contract between vcache and the pipeline. They are set only for the first vertex of a primitive.
2010-08-06draw: Mask out vertex flags in GS and stream output.Chia-I Wu
This fixes out-of-bound access to the vertices.
2010-08-06draw: Include draw_decompose_tmp.h in draw_pt_decompose.h.Chia-I Wu
Use draw_decompose_tmp.h to replace pipeline primitive decomposer.
2010-08-06draw: Include draw_decompose_tmp.h in draw_so_emit_tmp.h.Chia-I Wu
Use draw_decompose_tmp.h to replace stream out primitive decomposer.
2010-08-06draw: Include draw_decompose_tmp.h in draw_gs_tmp.h.Chia-I Wu
Use draw_decompose_tmp.h to replace GS primitive decomposer.
2010-08-06draw: Include draw_decompose_tmp.h in draw_pt_vcache_tmp.h.Chia-I Wu
Use draw_decompose_tmp.h to replace vcache primitive decomposer. As the new decomposer supports primitives with adjacency, vcache_triangle_adj and vcache_line_adj (and their variants that have flags) are added.
2010-08-06draw: Add draw_decompose_tmp.h.Chia-I Wu
Including draw_decompose_tmp.h defines a primitive decomposer. It is intended to replace the existing vcache/so/gs/pipe decomposers. This is based on draw_pt_vcache_tmp.h.
2010-08-04draw: Fix return type of draw_translate_vinfo_size.Vinson Lee
Fixes typo from commit b609cfc7c9c38f26e7e6d6f7dd5dd6d38f4ed209.
2010-08-04draw: Fix the edge flags of flatshade_first polygons.Chia-I Wu
This bug can be triggered by rendering polygons with glProvokingVertexEXT(GL_FIRST_VERTEX_CONVENTION_EXT); glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);
2010-08-03draw: check for instance divisors in vcache_check_run()Brian Paul
When we have instance divisors we don't really know which vertex elements we'll be fetching ahead of time. This fixes a bug in instanced drawing which was exposed by the new draw_vbo() code because of max_index not being ~0 as often as it used to be. The test for max_index >= DRAW_PIPE_MAX_VERTICES often hid this problem before.
2010-08-03draw: added a commentBrian Paul
2010-08-03draw: use instance divisor in draw_print_arrays()Brian Paul
