* mesa: Enable true refcounting for NullBufferObj.Michal Krol2010-02-092-2/+22
| | | | | | | | This object can be shared with another context, so we cannot just delete it when the owning context is being destroyed. Ensuring that buffer objects are properly refcounted guarantees NullBufferObj is destroyed when all references to it are removed.
* mesa: Fix null buffer object reference counting.José Fonseca2010-02-091-0/+11
| | | | | | | | Always use _mesa_reference_buffer_object, and never call ctx->Driver.DeleteBuffer() directly to prevent dangling pointers to the null buffer object. This fixes crash/assertions in sharedtex_mt and Autodesk Mudbox.

* vbo: Fix up in-place splitting for non-contiguous/indexed primitives.Francisco Jerez2010-02-031-51/+62
| | | | | | | | | | | | | | The in-place splitting code wasn't dealing with index buffers at all (and it was being called from vbo_split_prims for too big index buffers, causing some occasional corruption). Additionally, it wasn't taking into account primitives arrays with non-contiguous indices (e.g. given prim[0].start = 0 and prim[1].start = max_verts, it would happily call back the driver with (max_index - min_index) still greater than max_verts, causing infinite recursion). It still doesn't handle too large indexed vertex buffers: use vbo_split_copy for that.
* vbo: fix missing state validation bugsBrian Paul2010-01-291-14/+14
| | | | | | | | | | | | | | | Commit 2708ddfb06a36d8568e2aa130bf1f7d551fcd309 caused a few regressions. We need to check/validate state after calling bind_arrays() because it might set the _NEW_ARRAYS flag if the varying VP inputs change. The symptom of this problem was some attribute arrays being ignored (or interpreted as constant-valued) in glDrawRangeElements or glMultiDrawElements. A follow-on patch will add some additional asserts to try to catch this kind of thing in the future. (cherry picked from commit 3cba779e16935f7c3a0bfd8af48bd5e015068e96)
* mesa: Warn when indices are out of bounds, but do not skip the draw in debug ↵Brian Paul2010-01-291-3/+1
| | | | | | | | | | | | builds. The driver (or preferably the hardware) should handle out of bounds indices. If there are problems then it's better to detect those in the debug builds. (cherry picked from commit e3257912e006120f6ab611e77005eed1a464030a)

* vbo: if 'end' is out of bounds, clamp itBrian Paul2010-01-261-0/+4
| | | | | If we determine that the 'end' parameter to glDrawElements() is out of bounds, clamp it to the max legal index value.
* vbo: clamp DrawElements start/end to max possible valuesBrian Paul2010-01-261-0/+10
| | | | | Some apps are sloppy with their start/end values. Clamp them to max possible values to prevent problems later.

| * vbo: fix array index out of bounds error, and fix evaluator prioritiesBrian Paul2009-12-081-12/+21
| | | | | | | | | | | | | | 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.

| * vbo: fix out-of-bounds array accessBrian Paul2009-11-043-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | 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.

* | vbo: disable the GL_ARB_draw_elements_base_vertex rebase pathBrian Paul2009-09-211-1/+4
| | | | | | | | | | | | | | | | | | | | | | 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.

* mesa: Make MultiDrawElements submit multiple primitives at once.Eric Anholt2009-09-012-0/+162
| | | | | | | | | 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 <[email protected]>

* | vbo: Avoid extra validation of DrawElements.Eric Anholt2009-08-127-75/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
