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.

2009-05-08mesa/st: cope with non-ibo index data in st_draw_feedback.cKeith Whitwell
Previously only non-indexed or indicies-in-a-vbo cases were handled in this code. This change adds the missing regular indices-in-memory case.
2009-03-09st: use pointer_to_offset() cast wrapper to convert pointers to uintBrian Paul
Silences warnings with 64-bit builds. See comments for details.
2009-03-04gallium: Unify reference counting.Michel Dänzer
The core reference counting code is centralized in p_refcnt.h. This has some consequences related to struct pipe_buffer: * The screen member of struct pipe_buffer must be initialized, or pipe_buffer_reference() will crash trying to destroy a buffer with reference count 0. u_simple_screen takes care of this, but I may have missed some of the drivers not using it. * Except for rare exceptions deep in winsys code, buffers must always be allocated via pipe_buffer_create() or via screen->*buffer_create() rather than via winsys->*buffer_create().
