* vbo: Clean up unused variables in the vbo module.Mathias Froehlich2011-10-223-16/+1
| | | | | Remove some unused or unused but set variables from the vbo module.
* vbo: Redeclare bind_array() as non-static vbo_bind_array()Chad Versace2011-10-182-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <[email protected]> Signed-off-by: Chad Versace <[email protected]>
* mesa: Add dd_function_table::PrepareExecBeginChad Versace2011-10-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This hook allows the driver to prepare for a glBegin/glEnd. i965 will use the hook to avoid avoid recursive calls to FLUSH_VERTICES during a buffer resolve meta-op. Detailed Justification ---------------------- When vertices are queued during a glBegin/glEnd block, those vertices must of course be drawn before any rendering state changes. To enusure this, Mesa calls FLUSH_VERTICES as a prehook to such state changes. Therefore, FLUSH_VERTICES itself cannot change rendering state without falling into a recursive trap. This precludes meta-ops, namely i965 buffer resolves, from occuring while any vertices are queued. To avoid that situation, i965 must satisfy the following condition: that it queues no vertex if a buffer needs resolving. To satisfy this, i965 will use the PrepareExecBegin hook to resolve all buffers on entering a glBegin/glEnd block. -------- v2: Don't add dd_function_table::CleanupExecEnd. Anholt and I discovered that hook to be unnecessary. Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Chad Versace <[email protected]>
* mesa/vbo: Treat attribute 0 and vertex as the sameIan Romanick2011-10-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is supported by the pseudo-code on pages 27 and 28 (pages 41 and 42 of the PDF) of the OpenGL 2.1 spec. The last part of the implementation of ArrayElement is: if (generic attribute array 0 enabled) { if (generic vertex attribute 0 array normalization flag is set, and type is not FLOAT or DOUBLE) VertexAttrib[size]N[type]v(0, generic vertex attribute 0 array element i); else VertexAttrib[size][type]v(0, generic vertex attribute 0 array element i); } else if (vertex array enabled) { Vertex[size][type]v(vertex array element i); } Page 23 (page 37 of the PDF) of the same spec says: "Setting generic vertex attribute zero specifies a vertex; the four vertex coordinates are taken from the values of attribute zero. A Vertex2, Vertex3, or Vertex4 command is completely equivalent to the corresponding VertexAttrib* command with an index of zero." Fixes piglit test attribute0.

* Revert "vbo: Don't discount stride == 0 for testing all varyings in VBOs."Eric Anholt2011-10-011-1/+2
| | | | | | | | | | | | | | | | | This reverts commit d631c19db47181129811080bfa772b210d762d4d. The commit was broken, and ended up returning false all the time because nobody in the world binds every single possible vertex array. On further reflection, we don't want to discount stride == 0: This function is just used for deciding to calculate whether to compute the bonuds on the index, and there's no sense in computing index bounds when stride == 0. For the separate question of "how much data do I upload for this vertex element?", the i965 driver was fixed to upload the data. Fixes a regression of about 2x in 3DMMES, and most importantly, makes Hammerfight playable.

* vbo: Don't discount stride == 0 for testing all varyings in VBOs.Eric Anholt2011-06-231-2/+1
| | | | | | | | | | | | | | | | | In fixed function, stride == 0 (e.g. glColor4f() outside of the draw call) would get turned into uniform inputs, which is why it was ignored originally in this test. For shaders, drivers end up seeing a need to upload stride == 0 data, and get confused by needing to upload when vbo_all_varyings_in_vbos() returned true. In the 965 driver case, it wouldn't bother to compute the min/max index, and uploaded nothing if the min/max wasn't known. We've talked about removing the ff stride=0-into-uniforms code, so this check shouldn't be missed once that's gone.

| | | | | | | | | | | | | | See piglit dlist-fdo31590.c test and http://bugs.freedesktop.org/show_bug.cgi?id=31590 In this case we had node->prim_count=1 but node->count==0 because the display list started with glBegin() but had no vertices. The call to glEvalCoord1f() triggered the DO_FALLBACK() path. When replaying the display list, the old condition basically no-op'd the call to vbo_save_playback_vertex_list call(). That led to the invalid operation error being raised in glEnd(). NOTE: This is a candidate for the 7.10 branch.
