* 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.

* vbo: Don't bother checking for stride == 0 for "any varying in a VBO".Eric Anholt2011-06-231-2/+1
| | | | | | | We would still want to consider that data as being in a VBO even if we managed to produce this case, which as far as I know we can't. Reviewed-by: Brian Paul <[email protected]>

* vbo: remove node->count > 0 test in vbo_save_playback_vertex_list()Brian Paul2011-06-081-9/+11
| | | | | | | | | | | | | | 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.

* mesa/st: Prevent 'end' < 'start' in vbo_exec_DrawRangeElementsBaseVertex()José Fonseca2011-04-071-1/+6
| | | | | | | | We adjust 'end' to fit into _MaxElement, but that may result into a 'start' value bigger than 'end' being passed downstream, causing havoc. This could be seen with arb_robustness_draw-vbo-bounds, due to an application bug.

* vbo: add vbo_always_unmap_buffers()Brian Paul2011-03-013-1/+22
| | | | | | Drivers can call this function as needed. It tells the VBO module to always unmap the current glBegin/glEnd VBO when we flush. Otherwise it's possible to be in a flushed state but still have the VBO mapped.

* vbo: Fix GLES2 glVertexAttrib.Chia-I Wu2010-12-082-34/+48
| | | | | | | | | 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*.
* vbo: Drop second ATTR macro.Chia-I Wu2010-12-081-27/+1
| | | | | There is no need to have a special version of ATTR for !FEATURE_beginend, since 81ccb3e2ce708619f4c23537a237d61bdffdd35f.
* vbo: Avoid unnecessary copy to/from current in vertex format upgrade.Francisco Jerez2010-11-062-48/+63
| | | | | | | | | | | | | | | | | Rebuilding the vertex format from scratch every time we see a new vertex attribute is rather costly, new attributes can be appended at the end avoiding a copy to current and then back again, and the full attr pointer recalculation. In the not so likely case of an already existing attribute having its size increased the old behavior is preserved, this could be optimized more, not sure if it's worth it. It's a modest improvement in FlightGear (that game punishes the VBO module pretty hard in general, framerate goes from some 46 FPS to 50 FPS with the nouveau classic driver).

* Drop the "neutral" tnl moduleKristian Høgsberg2010-10-141-7/+7
| | | | | | | Just always check for FLUSH_UPDATE_CURRENT and call Driver.BeginVertices when necessary. By using the unlikely() macros, this ends up as a 10% performance improvement (for isosurf, anyway) over the old, complicated function pointer swapping.
