* mesa: Add a new GetTransformFeedbackVertexCount() driver hook.Kenneth Graunke2013-10-311-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DrawTransformFeedback() needs to obtain the number of vertices written to a particular stream during the last Begin/EndTransformFeedback block. The new driver hook returns exactly that information. Gallium drivers already implement this by passing the transform feedback object to the drawing function, counting the number of vertices written on the GPU, and using draw indirect. This is efficient, but doesn't always work: If vertex data comes from user arrays, then the VBO module needs to know how many vertices to upload, so we need to synchronously count. Gallium drivers are currently broken in this case. It also doesn't work if primitive restart is done in software. For normal drawing, vbo_draw_arrays() performs software primitive restart, splitting the draw call in two. vbo_draw_transform_feedback() currently doesn't because it has no idea how many vertices need to be drawn. The new driver hook gives it that information, allowing us to reuse the existing vbo_draw_arrays() code to do everything right. On Intel hardware (at least Ivybridge), using the draw indirect approach is difficult since the hardware counts primitives, rather than vertices, which requires doing some simple math. So we always use this hook. Gallium drivers will likely want to use this hook in some cases, but want to use the existing draw indirect approach where possible. Hence, I've added a flag to allow drivers to opt-in to this call. v2: Make it possible to implement this hook but only use this path when necessary (suggested by Marek).

* vbo: access VBO memory more efficiently when building display listsBrian Paul2013-10-161-8/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Use GL_MAP_INVALIDATE_RANGE, UNSYNCHRONIZED and FLUSH_EXPLICIT flags when mapping VBOs during display list compilation. This mirrors what we do for immediate-mode VBO building in vbo_exec_vtx_map(). This improves performance for applications which interleave display list compilation with execution. For example: glNewList(A); glBegin/End prims; glEndList(); glCallList(A); glNewList(B); glBegin/End prims; glEndList(); glCallList(B); Mesa's vbo module tries to combine the vertex data from lists A and B into the same VBO when there's room. Before, when we mapped the VBO for building list B, we did so with GL_MAP_WRITE_BIT only. Even though we were writing to an unused part of the buffer, the map would stall until the preceeding drawing call finished. Use the extra map flags and FlushMappedBufferRange() to avoid the stall.

| | | | | | | | | | | | | | | The main GL context's swtnl_im field is the VBO module's vbo_context structure. Using the name "swtnl" in the name is confusing since some drivers use hardware texturing and lighting, but still rely on the VBO module for drawing. v2: Forward declare the type and use that instead of void * (suggested by Eric Anholt). v3: Remove unnecessary cast (pointed out by by Topi Pohjolainen).

| | | | | | | | | | | | | | | | | | | | | | | The derived _PrimitiveRestart enable flag combines the PrimitiveRestart and PrimitiveRestartFixedIndex enable flags. However, DrawArrays is not supposed to do FixedIndex restart: From the OpenGL 4.3 Core specification, section 10.3.5 (page 302): "If PRIMITIVE_RESTART_FIXED_INDEX is enabled, primitive restart is not performed for array elements transferred by any drawing command not taking a type parameter, including all of the *Draw* commands other than *DrawElements*." The OpenGL ES 3.0 specification agrees by omission: "When DrawElements, DrawElementsInstanced, or DrawRangeElements transfers a set of generic attribute array elements to the GL..."
