* Fix invalid extern "C" around header inclusion.Mark Janes2015-03-051-0/+8
| | | | | | | | | | | System headers may contain C++ declarations, which cannot be given C linkage. For this reason, include statements should never occur inside extern "C". This patch moves the C linkage statements to enclose only the declarations within a single header. Reviewed-by: Jose Fonseca <jfonseca@vmware.com>

* mesa: Change args to vbo_count_tessellated_primitives.Paul Berry2012-12-181-1/+2
| | | | | | | | | | | | | | No functional change--this simply paves the way to allow futures patches to call vbo_count_tessellated_primitives() during error checking, before the _mesa_prim struct has been constructed. This will be needed for GLES3, which requires draw calls to fail if there is not enough space available in transform feedback buffers to accommodate the primitives to be drawn.

| | | | | | | | | | | | | | | | | | In the future we'd like to treat vertex arrays as a state and not as a parameter to the draw function. This is the first step towards that goal. Part of the goal is to avoid array re-validation for every draw call. This commit adds: const struct gl_client_array **gl_context::Array::_DrawArrays.

* vbo: introduce vbo_get_minmax_indices functionYuanhan Liu2012-01-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | Introduce vbo_get_minmax_indices() function to handle the min/max index computation for nr_prims(>= 1). The old code just compute the first prim's min/max index; this would results an error rendering if user called functions like glMultiDrawElements(). This patch servers as fixing this issue. As when nr_prims = 1, we can pass 1 to paramter nr_prims, thus I made vbo_get_minmax_index() static. v2: per Roland's suggestion, put the indices address compuation into vbo_get_minmax_index() instead. Also do comination if possible to reduce map/unmap count v3: per Brian's suggestion, use a pointer for start_prim to avoid structure copy per loop.

* mesa: Add count_tessellated_primitives() function.Paul Berry2011-12-201-0/+3
| | | | | | | | | | | This function computes the number of primitives that will be generated when the given drawing operation is performed. It accounts for the tessellation that is performed on line strips, line loops, triangle strips, triangle fans, quads, quad strips, and polygons, so it is suitable for implementing the primitive counters needed by transform feedback.

* mesa: implement DrawTransformFeedback from ARB_transform_feedback2Marek Olšák2011-12-151-1/+3
| | | | | | | | | | | | | | 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.
* vbo: Redeclare bind_array() as non-static vbo_bind_array()Chad Versace2011-10-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is necessary because i965 will need to call vbo_bind_array() when cleaning up after a buffer resolve meta-op. Detailed Explanation -------------------- The vbo module tracks vertex attributes separately from the gl_context. Specifically, the vbo module maintins vertex attributes in vbo_exec_context::array::inputs, which is synchronized with gl_context::Array::ArrayObj::VertexAttrib by vbo_bind_array(). vbo_draw_arrays() calls vbo_bind_array() to perform the synchronization before calling the real draw call, vbo_context::draw_arrays. Intel hardware accomplishes buffer resolves with a meta-op. Frequently, that meta-op must be performed within glDraw* in the moment immediately before the draw occurs (The hardware designers hate us...). After performing the meta-op, but before calling vbo_bind_array(), the gl_context's vertex attributes will have been restored to their original state (that is, their state before the meta-op began), but the vbo module's vertex attribute are those used in the last meta-op. Therefore we must manually synchronize the two with vbo_bind_array() before continuing with the original draw command (that is, the one requested with glDraw*). See brw_predraw_resolve_buffers(), which will be added in a future commit. Reviewed-by: Brian Paul <brianp@vmware.com> Signed-off-by: Chad Versace <chad@chad-versace.us>

* vbo: Fix GLES2 glVertexAttrib.Chia-I Wu2010-12-081-13/+13
| | | | | | | | | Attribute 0 has no special meaning in GLES2. Add VertexAttrib4f_nopos for that purpose and make _es_VertexAttrib* call the new function. Rename _vbo_* to _es_* to avoid confusion. These functions are only used by GLES, and now some of them (_es_VertexAttrib*) even behave differently than vbo_VertexAttrib*.

* i965: Don't rebase the index buffer to min 0 if any arrays are in VBOs.Eric Anholt2010-10-121-0/+1
| | | | | | | | | There was a check to only do the rebase if we didn't have everything in VBOs, but nexuiz apparently hands us a mix of VBOs and arrays, resulting in blocking on the GPU to do a rebase. Improves nexuiz 800x600, high-settings performance on my Ironlake 41% (+/- 1.3%), from 14.0fps to 19.7fps.

* vbo: Avoid extra validation of DrawElements.Eric Anholt2009-08-121-1/+5
| | | | | | | | | | | | | This saves mapping the index buffer to get a bounds on the indices that drivers just drop on the floor in the VBO case (cache win), saves a bonus walk of the indices in the CheckArrayBounds case, and other miscellaneous validation. On intel it's a particularly a large win (50-100% in my app) because even though we let the indices stay in both CPU and GPU caches, we still end up waiting for the GPU to be done with the buffer before reading from it. Drivers that want the min/max_index fields must now check index_bounds_valid and use vbo_get_minmax_index before using them.
