i965: Add a driconf option to disable flush throttling.
Normally when submitting the first batch buffer after a flush, we check whether the GPU has completed processing of the first batch buffer of the previous frame. If it hasn't, we wait for it to finish before submitting any more batches. This prevents GPU-heavy and CPU-light applications from racing too far ahead of the current frame, but at the expense of possibly lower frame rates. Sometimes when benchmarking we want to disable this mechanism. This patch adds the driconf option "disable_throttling" to disable the throttling mechanism. Reviewed-by: Eric Anholt <>
