* mesa: allow buffers to be mapped multiple timesMarek Olšák2014-02-258-56/+81
| | | | | | | | | | | | | | | | | | | OpenGL allows a buffer to be mapped only once, but we also map buffers internally, e.g. in the software primitive restart fallback, for PBOs, vbo_get_minmax_index, etc. This has always been a problem, but it will be a bigger problem with persistent buffer mappings, which will prevent all Mesa functions from mapping buffers for internal purposes. This adds a driver interface to core Mesa which supports multiple buffer mappings and allows 2 mappings: one for the GL user and one for Mesa. Note that Gallium supports an unlimited number of buffer and texture mappings, so it's not really an issue for Gallium. v2: fix unmapping in xm_dd.c, remove the GL errors there v3: fix the intel driver (by Fredrik) Reviewed-by: Fredrik Höglund <[email protected]>

* mesa: Rename ElementArrayBufferObj to IndexBufferObj.Kenneth Graunke2014-02-032-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | DirectX and most hardware documentation use the term "Index Buffer" to refer to a buffer containing indexes into arrays of vertex data, which allows random access to vertex data, rather than sequential access. OpenGL uses a different term for this concept: "Element Array Buffer". However, "Index Buffer" has become much more widespread. A quick Google search shows 29,300 hits for "Element Array Buffer" vs. 82,300 hits for "Index Buffer." Arguably, "Index Buffer" is clearer: an "element of an array" (or list) usually refers to an actual item stored in the array, not the index used to refer to it. The terminology is also already used in Mesa: some VBO module code for dealing with ElementArrayBufferObj names local variables "ib".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When reading through the Mesa drawing code, it's not immediately obvious to me that "ArrayObj" (gl_array_object) is the Vertex Array Object (VAO) state. The comment above the structure explains this, but readers still have to remember this and translate accordingly. Out of context, "array object" is a fairly vague. Even in context, "array" has a lot of meanings: glDrawArrays, vertex data stored in user arrays, gl_client_arrays, gl_vertex_attrib_arrays, and so on. Using the term "VAO" immediately associates these fields with the OpenGL concept, clarifying the situation and aiding programmer sanity.

* 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.
