Hi all, We finished a round of tests for AIM7 workload for the patch v5 by LKP, the result is as follows:

For power, we can see some benefits. In perticular, the stddev indicates the variation is smaller than v3.16-rc7 (all subtests are done at least for 5 times). To Jason, the format or specific metric is not directly comparable with your tests. If you can specify how to get the same look as your tests, we are happy to try.
