2010-01-26vbo: if 'end' is out of bounds, clamp itBrian Paul
If we determine that the 'end' parameter to glDrawElements() is out of bounds, clamp it to the max legal index value.
2010-01-26vbo: clamp DrawElements start/end to max possible valuesBrian Paul
Some apps are sloppy with their start/end values. Clamp them to max possible values to prevent problems later.

2009-12-08vbo: fix array index out of bounds error, and fix evaluator prioritiesBrian Paul
Fixes bug 25525. Plus, the GL_NV_vertex_program evaluators alias and override the convential evaluator maps, so set their state after the conventional maps.
2009-12-01vbo: make flush recursion check code per-contextBrian Paul
This fixes invalid failed assertions when running multi-threaded apps.

2009-11-04vbo: fix out-of-bounds array accessBrian Paul
The exec->vtx.inputs[] array was being written past its end. This was clobbering the following vbo_exec_context::eval state. Probably not noticed since evaluators and immediate mode rendering don't happen at the same time. Fixed the loop in vbo_exec_vtx_init(). Changed the size of the vbo_exec_context::vtx.arrays[] array. Added a bunch of debug-build assertions. Issue found by Vinson Lee.

2009-10-14mesa: added MESA_VERBOSE option 'draw' to debug glDrawArrays/Elements, etc.Brian Paul
2009-10-07mesa: rename display list functionsBrian Paul
_mesa_alloc_instruction() sounded like it was related to vertex/fragment program instructions, but it wasn't.
2009-09-30mesa/main: New feature FEATURE_beginend.Chia-I Wu
This feature corresponds to the Begin/End paradigm. Disabling this feature also eliminates the use of GLvertexformat completely.
2009-09-30mesa/main: Make FEATURE_dlist follow feature conventions.Chia-I Wu
As shown in mfeatures.h, this allows users of dlist.h to work without knowing if the feature is available.
2009-09-30mesa/main: Make FEATURE_evaluators follow feature conventions.Chia-I Wu
As shown in mfeatures.h, this allows users of eval.h to work without knowing if the feature is available.
2009-09-30mesa/main: New feature FEATURE_arrayelt.Chia-I Wu
This allows the removal of AEcontext.

2009-09-24vbo: limit number of warnings to 10Brian Paul
Otherwise some apps will emit tons of warnings.
2009-09-21vbo: added comment about max array indexBrian Paul
2009-09-21vbo: restore some lost warning outputBrian Paul
2009-09-21vbo: disable the GL_ARB_draw_elements_base_vertex rebase pathBrian Paul
This was introduced with commit 92d7ed8a20d4a018ce5324e6537ae7b478b9e5bf. It causes rendering of stray polygons (with sw rendering at least) when running the OGL Distilled / Picking demo (click on an object). This needs additional debugging to fix/restore. Found one suspect thing: in _tnl_draw_prims() there's some mixed signed/ unsigned arithmetic/comparing at line 422 that may be incorrect.
2009-09-21mesa: refine the error checking vbo_exec_DrawRangeElements()Brian Paul
If the 'end' index is out of bounds issue a warning as before. But instead of just no-op'ing the draw call, examine the actual array indices to see if they're OK. If the max array index is out of bounds, issue another warning and no-op the draw call. Otherwise, draw normally. This is a debug build-only feature since it could impact performance. This "fixes" the missing torus in the OGL Distilled / Picking demo.

2009-09-01mesa: Make MultiDrawElements submit multiple primitives at once.Eric Anholt
Previously, MultiDrawElements just called DrawElements a bunch of times. By sending several primitives down the pipeline at once, we avoid a bunch of validation. On my GL demo, this improves fps by 2.5% (+/- .41%) and reduces CPU usage by 70.5% (+/- 2.9%) (n=3). Reviewed by: Ian Romanick <ian.d.romanick@intel.com>
2009-08-28vbo: Fix array pointer calculation for MapBufferRange-mapped vertex data.Eric Anholt
We would end up with the offset from the start of the mapping rather than the offset from the start of the buffer.

2009-08-12vbo: Avoid extra validation of DrawElements.Eric Anholt
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.

2009-07-02vbo: If MapBufferRange fails, try MapBuffer instead.Corbin Simpson
Fixes segfaults with radeon winsys. (Probably libdrm_radeon doing something that it shouldn't.)
2009-06-30mesa/vbo: fix compile and replay of nodes ending in a FALLBACKKeith Whitwell
Where vbo save nodes are terminated with a call to DO_FALLBACK(), as in the case of a recursive CallList which is itself within a Begin/End pair, there two problems: 1) The display list node's primitive information was incorrect, stating the cut-off prim had zero vertices 2) On replay, we would get confused by a primitive that started in a node, but was terminated by individual opcodes. This change fixes the first problem by correctly terminating the last primitive on fallback, and the second by forcing the display list to use the Loopback path, converting all nodes into immediate-mode rendering. The loopback fix is a performance hit, but avoiding this would require a fairly large rework of this code.
