Kenneth Graunke 3eb6258db7 i965/query: Cache whether the batch references the query BO. Chris Wilson noted that repeated calls to CheckQuery() would call drm_intel_bo_references(brw->batch.bo, query->bo) on each invocation, which is expensive. Once we've flushed, we know that future batches won't reference query->bo, so there's no point in asking more than once. This patch adds a brw_query_object::flushed flag, which is a conservative estimate of whether the batch has been flushed. On the first call to CheckQuery() or WaitQuery(), we check if the batch references query->bo. If not, it must have been flushed for some reason (such as being full). We record that it was flushed. If it does reference query->bo, we explicitly flush, and record that we did so. Any subsequent checks will simply see that query->flushed is set, and skip the drm_intel_bo_references() call. Inspired by a patch from Chris Wilson. According to Eero, this does not affect the performance of Witcher 2 on Haswell, but approximately halves the userspace CPU usage.
