On SandyBridge, the BLT commands were split from the RENDER commands as well as the BSD split inherited from Ironlake. So we need to make sure we do exercise each ring, and in order to do so we also need to make sure each batch takes longer to execute than it takes for us to submit it. v2: Exercise each ring sequentially.
