27 * The HW has native support for occlusion queries, with the query result
28 * being loaded and stored by the TLB unit. From a SW perspective, we have to
29 * be careful to make sure that the jobs that need to be tracking queries are
30 * bracketed by the start and end of counting, even across FBO transitions.
32 * For the transform feedback PRIMITIVES_GENERATED/WRITTEN queries, we have to
33 * do the calculations in software at draw time.
